Utilization Patterns of Milk and Milk Products among Various End Users in Karnataka, India: A Comparative Analysis

The utilization patterns of milk and milk products in Karnataka were investigated through a study of 100 farmers and 50 consumers. The focus was on how milk was retained, consumed and transformed into various products. It was found that significant variation existed in milk production and consumption across different herd sizes. Small, medium, and large farmers were reported to produce an average of 33.80, 45.18 and 66.26 liters of milk per day, respectively, with family consumption accounting for 19.23 per cent, 17.37 per cent and 15.84 per cent of their production. Larger herds were associated with increased milk production, which allowed for a greater surplus to be sold. Utilization patterns showed that small farmers retained 6.5 liters of milk daily, consuming 32.94 per cent as liquid milk and converting 64.23 per cent into curd, with minimal ghee production. In contrast, large farmers retained 10.5 liters daily, consuming 43.80 per cent as liquid milk and converting 53.12 per cent into curd. This indicated a trend towards higher liquid milk consumption and varying product transformation depending on herd size. Consumer data indicated that rural households spent an average of ₹141.18 on 2.41 kg of milk products daily, while urban households spent ₹142.10 on 2.25 kg. Despite higher costs, urban consumers spent more on liquid milk, whereas rural consumers allocated more to curd and ghee. These findings reflected regional price differences and consumption preferences. Overall, the study highlighted the complex dynamics of milk utilization, with varying consumption patterns and product transformations observed across different farmer categories and consumer demographics. This information was deemed crucial for optimizing milk production and distribution strategies in Karnataka.

Effects of brewery by-products based silage on productive performance of crossbred dairy cows.

The present study aimed to evaluate the effect of an increasing levels of brewery by-products based silage on productive performances of 3/4 Friesian x Boran mid-lactating cows. Experimental cows had similar in initial milk yield (11.7 ± 1.0), average days in milk (81.7 ± 6.1) and live weight (LW, 430.7 ± 40.3kg) but different in parities (2-5).The dietary treatments were arranged randomly in 4 × 4 Latin Square Design that included ad libitum natural pasture hay feeding for all treatments as a roughage source plus a commercial dairy concentrate mix supplemented at 0.5kg DM (dry matter)/liter of milk produced/day for cows in the control group (T1) and 0.3, 0.5 and 0.7kg DM of brewery by-products based silage per liter of milk yield/cow/day for cows in T2, T3 and T4 groups, respectively. The study revealed that the daily milk yield of experimental cows was influenced by dietary treatments with relatively higher daily milk yield being recorded (P < 0.05) for cows in the T4 (13.9l) followed by T3 (13.8l). Milk composition of cows remained unchanged (P > 0.05) except for fat percentage of the milk that showed a declining trend (P < 0.05) with incremental inclusion levels of brewery by-products based silages. The highest net income (NI, 437.9 Eth. Birr) and marginal rate of return (MRR, 800.7%) was obtained for cows receiving brewery by-products based silage at the rate of 0.7kg/liter of milk yield as compared to cows in the other treatment groups. Further study is required on the long term effect of brewery by-products based silage supplementation on productive, reproductive performance, and milk microbial qualities.

DETERMINATION OF THE CARBON FOOTPRINT OF ANIMAL WASTE AND CLIMATE CHANGE; KARAMAN EXAMPLE

Climate change is a major concern around the world. In this context, the carbon footprint of animal waste is of critical importance for sustainability and climate change management. The aim of this study is to estimate the carbon footprint resulting from animal breeding and animal waste in the Karaman region. In the study, 2022 data was used and there are 1019277 sheep and 81368 cattle for Karaman. In the study, Tier 1 and Tier 2 approaches were used to estimate methane gas emissions related to both enteric fermentation resulting from animal digestive processes and manure management. According to the results of the study, the results obtained using Tier 1 and Tier 2 approaches are as follows: 0.4924-0.5014 kg CO2e per 1 liter of milk for Cattle. For sheep, it is 4.5167-6.5627 kg CO2e per 1 kg of meat. For goat, it is 5.0813-6.0231 kg CO2e per 1 kg of meat. These results can be taken into account when creating strategies to reduce methane gas emissions. It is recommended to add better quality and high energy content foods to the feed ration, especially to reduce enteric fermentation. In addition, this study is a resource for relevant researchers working in the field in calculating the carbon loads of animal waste and is thought to be a guide for decision makers and practitioners.

Identifying strategies to enhance the milking and operator efficiency of herringbone and rotary parlor systems in Ireland

International trends of increasing dairy herd sizes coupled with scarcity of labor has necessitated the enhancement of labor efficiency for dairy production systems. This study quantified the effects of infrastructure, automation, and management practices on the milking and operator efficiency of herringbone and rotary parlors used on pasture-based farms in Ireland. Data from 592 milkings across 26 farms (16 herringbones and 10 rotaries) was used. The metrics of cows milked per hour (cows/h), cows milked per operator per hour (cows/h per operator) and liters of milk harvested per hour (L/h) described milking efficiency. The metrics of total process time per cow (TPT, s/cow), milk process time per cow (MPT, s/cow), work routine time (WRT, s/cow), cluster time (CT, s/cluster), and attachment time per cow (ATC, s/cow) described operator efficiency. Automations investigated were backing gates, cluster flush, plant wash, cluster removers (ACRs), feeders, entry gates, rapid-exit, and teat spray. Additional operator presence at milking was also investigated. Herringbone and rotary parlors were assigned to quartiles from their cows/h per operator values to examine infrastructure, automations, and management practices variations. Fourth quartile herringbones based on cows/h per operator values (Q4) averaged 93 cows/h per operator using average system sizes of 24 clusters with 5 parlor automations. Q4 rotaries averaged 164 cows/h per operator using average system sizes of 47 clusters and an average CT of 13 s/cluster. Cows/h per operator values for Q4 herringbone and rotary parlors were 82% and 54% higher, respectively, than values observed on Q1 parlors, indicating the considerable potential to improve efficiency. To determine if infrastructure, automations, or additional operators at milking significantly affected operator efficiencies, general linear mixed models were developed. For parlor infrastructure, additional clusters had greater significance on operator efficiencies (MPT) for herringbones (-1.3 s/cow) as opposed to rotaries (-0.2 s/cow). Hence, increases in system size was likely to result in improved efficiencies for herringbones but less so for rotaries. For automations, ACRs significantly reduced herringbone TPT, CT, and WRT values by 13.3 s/cow, 18.9 s/cluster, and 32.6 s/cow, respectively, whereas rapid-exit significantly lowered CT by 18.6 s/cluster. We found no significant effect on rotary TPT, MPT, CT, or WRT values from the use of automatic teat sprayers. An additional operator at milking was found to significantly reduce herringbone TPT but not MPT or CT. For rotaries, a second operator had no significant effect on TPT, MPT, CT, or WRT values. We documented strong negative correlations between operator efficiencies (TPT, MPT) and milking efficiency (cows/h) for both herringbone (-0.91, -0.84) and rotaries (-0.98, -0.89). Strong negative correlations between the herringbone automation count and TPT (-0.80), MPT (-0.72), and CT (-0.75) suggested highly automated parlors were likely to achieve greater operator efficiencies than less automated parlors. The strong negative correlation (-0.81) between rotary milking efficiency (cows/h) and CT suggested lower CT values (i.e., rotation speed) resulted in increased milking efficiency. In conclusion, our study quantified the effects of parlor infrastructure, automation, and management practices on the milking and operator efficiency of herringbone and rotary parlors.

ИЗМЕНЕНИЕ МИНЕРАЛЬНОГО СОСТАВА МОЛОКА КОРОВ ПОД ВЛИЯНИЕМ БРИКЕТОВ-ЛИЗУНЦОВ

The aim of the study is to investigate the degree of influence of environmentally friendly lick briquettes Amirasol G(S)-Z and Amirasol G(S)-L on the mineral composition of milk, milk productivity and milk fat content of Caucasian brown cows of the mountain biogeochemical province of the Republic of Dagestan in the autumn-winter and spring-summer periods of keeping. During the use of lick briquettes in the diets of cows during the year, their positive effect on the mineral composition of milk, milk productivity and milk fat content was revealed. Moreover, a reliable increase was established in the milk of the experimental group of cows in the concentration of macroelements potassium, sodium, magnesium, calcium, phosphorus, respectively, by 12.17; 155.10; 52.82; 46.18; 93.96 %; microelements iron, zinc, manganese, copper, cobalt, iodine (CBI), selenium, respectively, by 101.84; 113.96; 256.01; 130.47; 265.85; 530.0; 275.91 % compared to the control group, compared to the average level of the physiological norm – by 19.66; 39.70; 5.84; 82.12; 92.96; 98.94; 83.17; 80.11; 94.08; 47.67; 210.89;109.73 %. In the control group of cows, the concentration of macro- and microelements was below the lower limit of the norm, with the exception of potassium and manganese, which were higher by 29.01 and 10.04 %, respectively, compared to the lower limit of the physiological norm. The use of lick briquettes in the diets of dairy cows during the year also contributed to an increase in milk productivity by 6.23 %, milk fat content by 5.0 % (0.20 abs.%), an additional 0.49 liters of milk per head per day were obtained on average for the group. The economic effect was 80,460 rubles, or 2,682 rubles per head during the experiment.

Estimation of economic equations as a management tool in feedlot dairy farming

The aim of this study was to evaluate Pearson's linear correlations between productive and economic indicators as well as to estimate economic equations as tools in dairy farming. We used the database of the Research Group, registered with CNPq under the title ‘Animal and Forage Production in Piaui’, which consisted of two experiments with feedlot lactating cows. Economic and productive indicators were employed. Correlations were determined by Pearson’s linear correlation analysis, using the ‘t’ test. Equations were estimated via regression, using Saeg software (Statistical and Genetic Analysis System), considering α = 0.05. Based on concepts related to Pearson's linear correlation and dairy farming management, we were able to find correlations that allowed us to estimate simple, yet very informative equations, which facilitated the interpretation of the management of a dairy farm. Among the studied variables, net present value, internal rate of return, the cost per liter of milk produced and net margin were those which most contributed to the estimation of equations.

Estimation of economic losses due to leptospirosis in dairy cattle

There are few studies that effectively quantify the economic losses resulting from problems caused by leptospirosis in naturally infected dairy cattle. Given this gap, the objective of this study was to propose and apply a method to quantify the economic losses resulting from productive and reproductive problems in a commercial dairy herd naturally infected by Leptospira spp. For this study, the zootechnical and economic indicators at a property with Jersey cattle were analyzed during the period from 2014 to 2017. The leptospirosis outbreak occurred in 2014, and the therapeutic approach was carried out between 2015 and 2017, with the latter considered the year of control of the outbreak. The adopted integrated control strategy consisted of dividing the herd according to the serological results obtained through the microscopic agglutination test, the treatment of reagents with streptomycin, and vaccination against leptospirosis of non-reagent heifers and cows. The method used to evaluate the economic indicators of the property was the calculation of the gross margin by taking into account the implicit and explicit cost parameters associated with the manifestation of leptospirosis. The prevalence rate of leptospirosis decreased from 49.4 % in 2015 to 21.6 % in 2017. There was a reduction in the abortion rate (from 40.00 % in 2014 to 9.00 % in 2017), in the stillborn rate (from 2.63 % in 2014 to 1.69 % in 2017) and an increase in the calving rate (from 65.00 % in 2014 to 86.00 % in 2017). In addition, there were increases in the number of lactating cows (from 38 in 2014–57 in 2017) and the mean times of lactation duration, which increased from 275 days in 2014–295 days in 2017. As a result, the average annual production of milk increased from 164,655 liters in 2014–248,521 liters in 2017. In 2014, when treatment hadn’t yet started, the gross margin per liter of milk sold, considering implicit and explicit costs, was US$0.00. In 2015 and 2016, US$0.27 and US$0.30 were obtained, respectively, for this variable. In 2017, with the disease under control on the property, the gross margin per liter of milk reached US$0.36. The gross margin per liter of milk sold was higher in the period when the disease was controlled, showing losses of up to 84 % of the gross margin during the outbreak. Immediate treatment of positive cows and preventive measures had a significant impact on improving the productive and economic efficiency of the property.

Milking to 2030: Economic and sustainability prospective of the Mexican dairy sector

Objective: This study aims to assess the productive and economic performance of the Mexican milk sector, particularly focusing on small and medium-scale dairy farms, and examining pessimistic, base, and optimistic scenarios. Design/methodology/approach: Employing a statistical univariate method with time series analysis (ARIMA), we analyzed productive efficiency and price behavior in Mexican dairy systems. Deterministic and stochastic estimations for production volume, milk price, and cattle inventory from 2021 to 2030 were established using confidence intervals to construct pessimistic (lower interval), base (mean), and optimistic (upper interval) scenarios. Results: The evaluated period witnessed an estimated 10.27% increase in production, equivalent to 576 million liters of milk, with an average annual growth rate of 1.0922%. Milk prices displayed an upward trend, with average prices of $0.66, $0.69, and $0.72 under pessimistic, base, and optimistic scenarios, respectively. In 2030, a 22% price increase compared to 2021 was observed. Considering a base price of $0.45 USD per liter in 2030, costs under pessimistic, base, and optimistic scenarios were $1,658.21, $1,756.43, and $1,855.31, resulting in profits of $1,160.75, $1,229.50, and $1,022.45 from milk sales. Cattle inventory exhibited an upward trend, paralleling milk volumes and prices. Limitations on study/implications: The study's use of a univariate method may incompletely capture market dynamics complexity, potentially underestimating the impact of external market forces and global economic conditions on milk prices. Findings/conclusions: To secure forecasted milk volumes in base and optimistic scenarios, maintaining and enhancing good management practices is crucial. Additionally, addressing the imperative to augment production efficiency and improve environmental sustainability and animal welfare is essential.

Production Risk Analysis of Dairy Production Cooperative, Bogor, West Java

Abstract Bogor Dairy Production Cooperative (KPS Bogor) is one of the largest dairy cooperatives in Indonesia. Consisting of 127 active members, KPS Bogor produces an average of 78.8 liters of milk per farmer daily. However, the quantity and quality of milk produced fluctuate significantly, leading to income fluctuations for dairy farmers. This situation might indicate production risks faced by dairy farmers. This research aims to analyze the production risk KPS Bogor dairy farmers face. The study analyzes the variance level, coefficient of variation (CV), and the lower limit of dairy farming in KPS Bogor. The results showed that the production risk faced by dairy farmers was categorized as the “very high” category, with a CV value of 0.27 or 27 percent. Sensitivity analysis shows that dairy farmers at KPS Bogor faced the highest risk when the milk price reached the highest price, about 43 percent. Meanwhile, the lowest risk might occur from the production risk.

Milk productivity of queens, growth of purebred and crossbred young animals of the southern beef breed

Relevance. The safety of lambs is the most important factor affecting the efficiency of the industry. It is of particular relevance for multiple breeds. The level of dairy productivity of ewes is one of the factors affecting the growth and development of lambs, their safety before weaning. Milk productivity is positively correlated with the dynamics of the live weight of lambs.The aim of the study was to study the milk content of crossbred ( 1/2 southern meat and 1/2 Katum) and purebred (southern meat) ewes, the effect of this indicator on the growth of lambs.Methods. The objects of the study were purebred (n = 46), crossbred ( n = 30) ewes and their lambs. To determine the amount of milk produced by a ewe over 20 days, the increase in live weight of lambs during this period was multiplied by a factor of 5 (on average, up to 5 liters of milk are required for an increase of 1 kg). In multiple-fetal ewes, milk production was determined by multiplying the sum of the growth of all lambs in the litter by 5.Results. The number of lambs in the litter and the genotype of the ewes have a statistically significant effect on the live weight of lambs at birth and the milk production of ewes. Lambs born alone in a litter exceeded double lambs by 18.1% and triple lambs by 22.6% in live weight. Multiple ewes are superior in milk production to ewes with one lamb. In terms of the amount of milk produced in 20 days, ewes with triplets exceeded their peers with one lamb by 2.24 times, and with twins — 1.52 times. Crossbred (1/2 southern meat and 1/2 katumskaya) ewes are higher in milk productivity than the maternal breed.

Reproducible isolation of bovine mammary macrophages for analysis of host pathogen interactions

BackgroundMacrophages residing in milk are vital during intramammary infections. This study sought to develop a method enabling the investigation of macrophage responses to pathogens. Streptococcus uberis is the predominant cause of bovine mastitis UK-wide and its pathogenesis is unusual compared to other intramammary pathogens. Previous studies utilise macrophage cell lines, isolated bovine blood derived monocytes, or macrophages from raw milk through complex or inconsistent strategies such as fluorescence activated cell sorting (FACS), centrifugation and selective adherence, and CD14 antibody-microbeads. The centrifuge steps required in the initial stages often damage cells. Thus, the aim of this study was to develop a reliable, reproducible, and cost-effective method for isolating mammary macrophages from milk in a way that allows their culture, challenge with bacteria, and measurement of their response ex-vivo.ResultsThis method achieves an average yield of 1.27 × 107 cells per litre of milk. Whole milk with somatic cell range of 45–65 cells/µL produced excellent yields, with efficient isolations accomplished with up to 150 cells/µL. This strategy uses milk diluted in PAE buffer to enable low-speed centrifugation steps followed by seeding on tissue-culture-treated plastic. Seeding 1,000,000 milk-extracted cells onto tissue culture plates was sufficient to obtain 50,000 macrophage. Isolated macrophage remained responsive to challenge, with the highest concentration of IL-1β measured by ELISA at 20 h after challenge with S. uberis. In this model, the optimal multiplicity of infection was found to be 50:1 bacteria:macrophage. No difference in IL-1β production was found between macrophages challenged with live or heat-killed S. uberis. Standardisation of the production of IL-1β to that obtained following macrophage stimulation with LPS allowed for comparisons between preparations.ConclusionsA cost-effective method, utilising low-speed centrifugation followed by adherence to plastic, was established to isolate bovine mammary macrophages from raw milk. This method was shown to be appropriate for bacterial challenge, therefore providing a cost-effective, ex-vivo, and non-invasive model of macrophage-pathogen interactions. The optimal multiplicity of infection for S. uberis challenge was demonstrated and a method for standardisation against LPS described which removes sample variation. This robust method enables, reproducible and reliable interrogation of critical pathogen-host interactions which occur in the mammary gland.

Intramammary treatment of clinical mastitis quarters with ceftiofur does not cause anbiotic residues in adjacent untreated quarters.

The study was carried out in dairy cows to elucidate whether treatment of clinical mastitis quarters with Spectramast® LC (ceftiofur hydrochloride, 125 mg, Zoetis) created a reason for discarding milk from adjacent untreated healthy quarters. The antibiotic was infused once daily in the affected mammary quarter for four days. Forty-nine cows were evaluated after diagnosis of clinical mastitis in three or fewer udder quarters. In all cases, quarters that did not receive treatment had milk samples collected one day after the end of treatment. All milk samples from untreated quarters were below the maximum permissible limit for the presence of antibiotic residues after analysis with the BetaStar S Combo test. Pharmacokinetic and pharmacodynamic characteristics may explain this finding. We conclude that it is feasible to use milk from untreated quarters of animals that have been treated with Spectramast® LC. We also reiterate the need to carry out tests with other pharmacological bases, and that the results found in this experiment cannot be extrapolated to other drugs.Dairy cattle have considerable importance in the development of the Brazilian economy, being directly linked to economic and social progress. In the first half of 2020, 12.1 billion liters of milk were produced in Brazil and in 2019, there was a new record of 25.01 billion liters produced (IBGE, 2020). This production comes from a wide variety of production systems, coming from smallholder farmers as well as from large companies that use the latest technologies available on the market. Dairy production is a complex activity. For one to obtain economical success, several aspects must be monitored. Maintaining the health of animals is a top priority, and the literature suggests that various diseases are a common challenge for dairy producers. Mastitis is the main disease that affects dairy cows, responsible for considerable economic loss and significant zootechnical and productive challenges (Ruegg, ). It is considered the second leading cause of cow culling in dairy herds, behind reproductive problems. Mastitis is characterized by infection of the mammary gland and may or may not occur with inflammation, generating changes in the mammary tissue and properties of the milk. It is classifield into clinical or subclinical mastitis, according to presence or absence of clinical signs, and into contagious or environmental based on the causative agent (Correa et al., ).

Evaluation of Lipin 1 polymorphisms for genetic markers in association with performance traits in Azikheli buffalo

Lipin 1 regulates lipid metabolism in mammary glands. Genetic variation in lipin 1 gene is thought to effect milk production in dairy animals. This study aimed to investigate the association of SNPs in the exon 6 and 8 of the lipin 1 gene with milk yield in Azikheli buffalo from Swat, Pakistan. Azikheli buffaloes raised in a farm were selected based on their milk yield records. Three buffaloes were selected from the high milk yielding group with an average production of 12.96 ± 0.83 liters per day, and three from low yielding group producing 6.12 ± 0.28 liters of milk per day. Genomic DNA was extracted from the blood samples of these buffaloes, which were used to amplify exon 6, 8 the adjacent introns (6, 7 and 8) of the lipin 1 gene. The PCR products was sequenced through sanger sequencing. A total of 45 SNPs were found in the targeted regions of the lipin 1 gene in both high and low yielding buffaloes. Overall, four missense variants (g.62048T>C; Met399Thr and g.62069C>A; Pro406His) were found in the exon 8 of lipin 1 gene in Azikheli buffalo. Milk yield was positive correlated with SNP g.62048T>C; Met399Thr that was more frequent (0.83 vs 0.33) in high milk yielding buffaloes compared to the low yielding group. SNP g.62069C>A; Pro406His was unique to low milk yielding buffaloes suggesting its negative association with milk yield. Moreover, the visualization of 3D structure of the lipin I protein constructed using Phyr2 web server and the Missense 3D analysis identified no structural damages caused by the reported SNPs on the target protein. In conclusion, SNPs g.62048T>C; Met399Thr and g.62069C>A; Pro406His could serve as potential genetic markers for increasing milk productivity in buffaloes.

FOOT-AND-MOUTH DISEASE AND ITS EFFECT ON MILK YIELD: AN ECONOMIC ANALYSIS ON CATTLE AND BUFFALO HOLDERS IN HYDERABAD, SINDH

An investigation of the impact of foot-and-mouth disease (FMD) on milk production among cattle and buffalo farmers was conducted in Hyderabad, Sindh, Pakistan. 120 farmers who owned buffaloes participated in the study, equally distributed across the upper and lower parts of Hyderabad. Clinical symptoms led to the initial suspicion of FMD, which was later validated by field tests or laboratory findings. Prior to FMD, a buffalo produced an average of 12 liters of milk every day. However, throughout the course of the next 60 days, milk output drastically dropped after the commencement of the clinical illness. In one region, the projected milk loss per buffalo during this time was about 250 liters, whereas in the other, it was about 210 liters. According to the study, the total milk loss for the 120 lactating cattle and buffaloes was about 5,914,800 Pakistani rupees. Based on the supposition that cow milk was worth around 250 PKR per liter and buffalo milk about 200 PKR, this computation was made. This demonstrates the FMD's significant economic impact on local milk production. The expected benefit-to-cost ratio for immunizing all animals in the two locations was calculated to be 6.1 under the assumption that giving a high-quality vaccine that corresponds to the circulating FMD strains might avoid clinical illness.

The effect of liquid feeding period on the growth performance of calves

In this research, health records of calves born in a private dairy cattle farms with a capacity of 400 dairy cows in Ereğli between October 2020 and October 2021 were evaluated. The data determined in the 70 days from birth to weaning of the calves were recorded individually. The birth and weaning weights of the calves were measured at monthly intervals with a sensitive electronic scale up to 100 kilograms. Calves were barned in individual calf hutches and roughage and concentrate feed were offered separately and freely in front of them. Calves received colostrum from their mothers for 3 days. For 70 days, they were fed totally 6 litres of milk twice a day. Commercial calf growth feed with 18% crude protein and 2800 Kcal/kg ME energy was purchased and high quality alfalfa grass produced in the farm was used in calf feeding. Health observations of the calves were made by the technician by scoring cough, nasal discharge, condition of eyes and ears and faeces according to the results of the health observations.

Türkiye’nin Kuzeydoğu Anadolu Bölgesinde Buzağı Yetiştirme Uygulamaları: Erzurum İli Horasan İlçesi Örneği

The aim of this study was to assess calf rearing methods applied in 500 cattle farms in the Horasan district of Erzurum province. Data used in this study were obtained through face-to-face interviews with cattle breeders. In 69.5% of the enterprises operating within Horasan county, the exact quantity of milk consumed by calves could not be determined due to the fact that they are fed by nursing from their mothers. On the other hand, the proportions of farms feeding calves 1, 2, 3, 4, 5 and 6 liters of milk per day were determined as 0.4%, 0.6%, 5.7%, 3.6%, 8.9%, and 11.3%, respectively. In 38.4% of cattle enterprises in the county, calves were fed with milk while their mothers were being milked, whereas in 27.6% of cattle farms, calves were weaned at 4 months of age, and in 24.3% at 5 months. Furthermore, it was also observed that the most of breeders (72.7%) considered the birth weight of calves as a criterion to decide on the quantity of milk to be provided to them. On these farms, the methods of feeding colostrum to calves were by sucking their mothers with a percentage of 54.3%, followed by bottle feeding with a percentage of 45.5% and the bucket method with a very low percentage of 0.2%. Furthermore, calves in Horasan County usually begin to be given calf starter feed either at the age of 2 weeks (28.3%) or 3 weeks (28.1%), while dry hay is generally introduced to the most of calves (42.0%) at the age of 2 weeks. In conclusion, some inaccuracies in calf rearing practices were identified in Horasan county of Erzurum province and solutions were proposed to address these problems.

Development of a Portable Cool Box to Increase Milk Distribution Capacity

The SN Multipurpose Cooperative has a business of collecting pure cow's milk from dairy farmers. Milk is processed by cooling it to a certain temperature. Pure milk from cooperatives sent to milk factories can be rejected by milk factories for various reasons so that dairy farmers experience losses. The SN Multi-Business Cooperative carries out business development, namely pure milk is further processed by the cooperative into ready-to-drink processed milk products. Business development in the field of processing pure milk products will provide a greater selling value compared to pure milk sold directly to milk factories. Distribution and delivery of processed milk to consumers is carried out using motorbikes. To carry processed milk, every motorbike rider uses a basket bag made of thick cloth which is placed on the back and contains around 30 liters of milk. Inside this bag, ice cubes are placed to maintain the temperature of the processed milk. Over a long period of time the ice cubes will melt into water and seep into the basket bag and damage the basket bag. With the development of a portable toll box, it is possible to maintain milk temperature for longer as well as anthropometric arm length and upwards. The cool box installed on the motorbike is equipped with foam in the cooling box. The distributed capacity is greater to 64 liters.

Analysis of the Technical and Economic Performance of Dairy Farms in Algerian Conditions: The Case of the Wilaya of Tizi-Ouzou

The aim of this work is to carry out a comparative study of the costs of milk production for the two zones, plain and mountain, in the region of Tizi-Ouzou. Sixty-four farmers living in both areas were interviewed and surveyed. With an average of 12.5 cows per farm, there was no difference in the number of dairy cows between the two zones (P=0.586). Fodder consumption was 24.8 and 30.9 kg/cow/day in the mountain and plain areas respectively, a significant difference (P&lt;0.0001). Milk productivity was not significantly different (P = 0.202) between farmers in the two areas. The average was 21.7 litres per cow per day. The total cost of producing one litre of milk was 41.05 AD/L and 35.5 AD/L respectively, a significant difference (P &lt; 0.0001) between the two areas. The cost of feeding differs significantly (P &lt; 0.0001) between the two areas. Feed is more expensive in the mountains than in the lowlands (37.62 vs. 30.81 AD/L). The cost of buying hay was the most significant difference in feeding costs (P = 0.002). These costs were 17.43 vs. 12.73 AD/ha, respectively. There is a small difference in the cost of farm labour (P=0.095). It is lower in the mountain area (0.64 vs. 1.19 AD/L) than in the plain area. The main item in the total cost of milk production is the cost of feed. It represents 90 % and 85 % respectively in the mountain and in the plain areas. Forage area is a limiting factor for the development of milk production in the Tizi-Ouzou region. In the context of territorial development, it is proposed to develop fodder and silage production in regions of Algeria where there is an abundance of arable land and to transfer this fodder to dairy basins such as Tizi-Ouzou to feed dairy farms.

Selected Parameters Affecting the Electricity Consumption of Automatic Milking Systems

Abstract The paper presented is aimed at the determination of electricity consumption at selected dairy farms during milking employing automatic milking systems (AMS). The research was focused on the determination of electricity consumption during the performance of essential activities that are related to the AMS utilization, i.e., electricity consumption by a single AMS unit per day, by a single assembly compressor per day, by a single AMS unit and a single assembly compressor per day, per milking, and per 1 litre of milk. Measurements were conducted at eight dairy farms in Central Europe that house dairy cows of the black-spotted Holstein cattle breed. The cattle groups assessed comprised 95 to 105 animals subjected to milking over the entire observed period. On the basis of the measurements conducted, it was observed that the average amount of energy consumed per 1 litre of milked milk was 0.0232 kWh over the entire observed period. Regarding the essential activities, the results obtained indicate that the energy consumption throughout the year is relatively balanced, despite the fact that it is affected by a wide range of factors, including chiefly the herd management, as well as overall organization of entire farm, milk yield, health status of cattle, current climatic conditions, fodder quality, etc.
