Farmer experiences with goat raising in Lao PDR: implications for improving husbandry and sustaining viable systems

ABSTRACT Goat raising has increased in Lao People’s Democratic Republic due to meat demand from Vietnam. Goat production is low input using free grazing and minimal husbandry. Technical constraints are well known but socio-cultural contexts are poorly understood. This paper describes qualitative research on farmer’s motivations, experiences and learning pathways, to improve goat husbandry. Semi-structured interviews were conducted with 30 smallholder goat farmers in Lao’s South-Central province of Savannakhet. The interviews revealed that farmers relied on their experiences and observations of goat raising in their communities to make their management decisions. Trial and error was a valued learning strategy. Farmers took guidance from the exchange of goat raising experiences with other goat farmers and preferred participatory learning that fostered discussion in familiar village settings. Lao smallholder goat farming systems are a product of compromise across a number of resources. Project interventions that required low investments of labour, land or capital were most readily implemented and adapted by farmers. This study questions the assumption that project interventions are inherently optimal and beneficial for smallholder farming systems. Recommendations propose how farmer’s experiences, constraints and preferences can be incorporated into development approaches to ensure management system changes reflect the desires of smallholder farmers.

Analysis of Reproductive Performance of Female Peranakan Etawa Goats in Toari District, Kolaka Regency

The Peranakan Etawa Goat, a type of livestock highly sought after in Indonesia, particularly in the region of Southeast Sulawesi, is renowned for its ability to reproduce and adapt to the local environment. This research was conducted between April and July 2023 in the Toari District, Kolaka Regency, deliberately chosen as one of the centers of Peranakan Etawa Goat production. The population under study consisted of female Peranakan Etawa Goats owned by farmers in the villages of Ranojaya, Wonua Raya, and Rahabite. Data collection was carried out through direct interviews with respondents and secondary data collection from relevant agencies. The observed variables included the Reproductive Performance of the Peranakan Etawa Goats, such as Estrus Signs, Puberty, Mating (S/C), and Birth (litter size), which were then organized and presented in percentage form. Descriptive analysis was conducted to depict the characteristics and findings of the data. The findings indicate that the reproductive performance of Peranakan Etawa Goats in the Toari District is suboptimal, with puberty achieved at the age of 8-9 months and the duration of estrus ranging from 24-36 hours

The role of goat production in smallholder systems in Lao PDR: implications for improving productivity and scaling up production

Context Rising demand from Vietnam for Lao goat meat has triggered a rapid increase in goat numbers in Lao Peoples Democratic Republic (Lao PDR). Despite the increased market opportunity for smallholder farmers in Laos, goat production remains low input within free-grazing management systems. Aims Qualitative research was conducted to explore the role that goat production plays in farmers’ livelihood strategies and farming systems, including the benefits and associated trade-offs, so as to inform development approaches to improve goat husbandry and productivity. Methods Semi-structured interviews were conducted with 30 smallholder goat farmers across five villages in southern-central Laos. Interview transcripts were analysed using grounded theory methodology with the assistance of the Nvivo 12 software program. Key results The interviews showed that goats were a profitable and liquid asset for farmers. Income from goats was used for small expenses that occurred frequently or at short notice, such as household loans or debts, utility and medical costs and buying food and clothing for family members. Goats had socio-cultural purposes, with some farmers preferring to consume goats during celebratory occasions over other livestock species. Managing goats was easy and benefited the wider farming system by providing goat manure to fertilise crop plantations. Conclusions Goat productivity and goats’ unique subsistence and socio-cultural roles can be enhanced by improving goat kid management, goat-house design and cleaning, and by implementing disease management. These activities can be low input. Implications The government policy and future development projects in Laos should focus on increasing goat productivity rather than increasing the scale of farmers’ goat enterprises. The majority of farmers may not benefit from significantly increasing the scale of their goat enterprises because of trade-offs associated with free-grazing management, including goats damaging crops or becoming lost or involved in accidents such as dog attacks and car accidents.

Indigenous Goat Populations in Northwestern and Western Zones of Tigray Region, Ethiopia: Characterization of Major Husbandry Practices and Kidding Patterns

The survey was conducted before the war (before October 2020) in Tigray Region, Ethiopia. Goats are highly concentrated in the lowland areas than in the highlands of Ethiopia. Sample households of Begait (102), Hassan (106) and Arado (181) goats were randomly involved in the face-to-face interview. Statistical Package for Social Sciences software was used for data analysis. Illiterate respondents were in Begait (42%), Hassan (29%) and Arado (55%). Cattle and goats were the major economic sources in Begait (10.19±9.1 Tropical Livestock Unit (TLU), 4.30±2.8 TLU) and Arado (4.77±3.2 TLU, 1.27±0.9 TLU) respondents. The mean flock size of Arado goat population (12.65±9.9) was significantly (P<0.005) lower than the mean flock sizes of Begait (43.02±28.1) and Hassan (70.29±52.6) populations. Animals went to water source in most respondents (100.0% of Begait, 67.0% of Hassan and 87% of Arado), and river was the major water source for the animals of about 47% of Begait, 43% of Hassan and 79.0% of Arado respondents. Animals of about 56% of Hassan and 57% of Arado respondents travelled a distance of 1-5 Kilometer (Km) to obtain water, and dry season daily watering frequency of once a day was dominantly practiced in about 88% of Begait and 83% of Hassan respondents. Diseases and external parasites were reported in Begait (96%, 85%), Hassan (98%, 90%) and Arado (67%, 87%) respondents which affected indigenous goat productivity. There was no access to veterinary service centers (VSCs) in about 47% of Begait, 65% of Hassan and 93% of Arado respondents, and some respondents in about 24% of Begait and 17% of Hassan travelled a distance of greater than 10 Km to reach VSCs. Own buck use for mating and buck birth in own flocks were exhibited in Begait (93%, 85%), Hassan (95%, 76%) and Arado (38%, 35%) respondents, respectively. Uncontrolled mating and buck use outside of own flock were practiced in Begait (70%, 73%), Hassan (43%, 65%) and Arado (100.0%, 100.0%) respondents due to most goats graze in communal lands, respectively. Unknown buck to does ratio was practiced in 41% of Begait and 39% of Hassan respondents. Unknown buck to does ratio and a ratio of one buck to all does in the flock were practiced in Arado (8%, 67%) respondents, respectively, and crossbreeding was highly practiced in Begait respondents (41%). The dominant kidding months of Begait and Arado goat populations were in September up to November whilst that of Hassan goat population were in October up to December. Castration and traditional castration method were practiced in Begait (54%, 54%), Hassan (39%, 37%) and Arado (70%, 64%) respondents, respectively. Community education, access to water, access to VSC, buck to doe ratio, kidding pattern improvement and castration to control inbreeding need critical attention.

Genome-wide single nucleotide polymorphisms reveal the genetic diversity and population structure of Creole goats from northern Peru

Goat farming constitutes a significant source of income for farmers in northern Peru. There is currently an absence of information about the genetics of Peruvian Creole goats that would enable us to understand their origins and genetic spread. The objective of this study was to estimate the genetic diversity of Creole goats from northern Peru using SNP markers. This study involved the collection of 192 male Creole goats from three key goat production geographical departments in northern Peru. These goat samples were genotyped using the GGPGoat70k SNP panel. To explore the genetic influence of other breeds on Peruvian Creole goats, our dataset was combined with previously published SNP genotypes. External data set includes multiple breeds genotypes sampled from Argentina, Brazil, Spain, and Alpine breed from Italy, France, and Switzerland. After quality control 52,832 autosomal SNPs were used to assess genetic diversity in the Peruvian goats. For the population structure analysis of the merged data 20,513 common SNPs were used. Estimations for expected heterozygosity (He), observed heterozygosity (Ho), and inbreeding coefficient (FIS) were computed for the Peruvian groups. AMOVA, principal component analysis and ADMIXTURE were conducted to evaluate the population structure in the two data sets, Peru and merged. The results revealed a considerable genetic diversity, with Ho values ranging from 0.40 to 0.41 for the Peruvian sampling groups, and inbreeding coefficient was notably low for Peruvian goat. The population structure analysis demonstrated a distinction (p < 0.05) from other breeds. These findings suggest a level of genetic differentiation of the Peruvian goat population among other breeds, although further research is needed considering samples from other Peruvian areas. We expect this study will contribute to define genetic management strategies to prevent the loss of genetic diversity in Peruvian goat populations and for upcoming advancements in this field.

Goat flock abortion: a retrospective study at Abergelle Agricultural Research Center, Tigray, Ethiopia

BackgroundSmall ruminants are the principal component of livestock production in Tigray region, Ethiopia. But their productivity is affected by various factors. According to farmers and expert observation, goat abortion is among the leading causes of production losses in Tanqua-Abergelle district. However, study findings that examine the extent of distribution and economic impact of abortion cases in goats in the district are scarce. This retrospective study investigated the occurrence of abortion and its associated risk factors in three goat breed types at Abergelle Agricultural Research Center goat breeding site over a seven year period. The study included a total of does above one year old, and data were collected from a casebook that was specifically prepared for abortion cases. A thorough follow up was conducted to identify abortion cases. Additionally, a community survey was conducted in selected villages where the research center is located.ResultsThe overall abortion proportion was 29.8% in the goat farm. Begait goat breeds had the highest abortion proportion (50.9%, CI 0.36–0.64) in 2015/16. Multivariate logistic regression analysis identified year, season, age and breed as major risk factors of abortion occurrence at flock level. Accordingly, the likelihood of goats experiencing abortion during the dry season (proportion = 34) was 1.87 times higher compared to those in the wet season (proportion = 22.8). Begait breeds had a higher incidence of abortion (proportion 37.5%, OR 4.87, CI 2.49–10.35) compared to other breeds. Age was negatively associated with abortion, suggesting that older goats (OR = 0.67) had a higher relative risk than younger goats (OR = 0.57). Moreover, the study noted a high incidence of abortion during the years 2014/15 to 2016/17 (proportion = 35.7–39.7). Within-breed analysis revealed that age and season were significant risk factors for Abergelle and Begait breeds, respectively by using a multivariate logistic regression analysis. A community survey indicated that 89.7% households responded their goats experienced abortion.ConclusionsThis study highlighted the high prevalence of goat abortion at Abergelle and identifies important risk factors associated with its occurrence. The findings can inform targeted interventions to reduce abortion rates and improve goat productivity in the district.

Optimizing Feed Formulation Strategies for Attaining Optimal Nutritional Balance in High-Performing Dairy Goats in Intensive Farming Production Systems

Abstract Genetic factors play a pivotal role in shaping feed formulation strategies for dairy goats, influencing milk production, composition, and overall productivity through the modulation of genetic parameters and polymorphisms associated with milk protein fractions and yield. Moreover, environmental challenges, including heat stress and feed availability fluctuations, pose significant hurdles in achieving optimal nutrition and performance, necessitating precision livestock farming and the utilization of local by-products to mitigate their impact on herd health and productivity. In addition, nutritional interventions, such as supplement utilization and alternative feed incorporation, offer promising avenues for addressing specific deficiencies and enhancing overall performance, from fatty acid supplementation to herbal feed additives, while balancing rations to meet evolving nutritional needs and ensuring long-term sustainability remains paramount for optimizing herd nutrition, health, and performance in intensive dairy goat production systems. The aim of this study was to explore the multifaceted influences of genetic factors, environmental challenges, and nutritional interventions on feed formulation strategies and overall herd nutrition, health, and performance in intensive dairy goat production systems.

Seroprevalence and risk factors of Toxoplasma gondii in sheep and goats of North West Province, South Africa

BackgroundThe protozoan parasite Toxoplasma gondii causes toxoplasmosis, one of the most prevalent parasitic zoonotic diseases with significant economic and public health implications worldwide. Infection with the parasite has a significant adverse effect on sheep and goat production and can frequently go undetected in the herd, resulting in abortions and weak or dead offspring. Although there are few studies on seroprevalence and risk factors associated with T. gondii infections in livestock in other provinces of South Africa, there is no data in the North West province. Therefore, a cross-sectional study was conducted to investigate the seroprevalence of T. gondii and risk factors associated with exposure in sheep and goats of the North West province of South Africa. Sera from 439 livestock (164 sheep and 285 goats) were collected and analysed for the presence of T. gondii IgG antibodies using indirect ELISA (Enzyme-linked immunosorbent assay). An assessment of potential risk factors in farms associated with seropositivity was also conducted using a structured questionnaire.ResultsOut of the 439 tested sheep and goats, 13.9% (61/439) were positive for IgG antibodies against T. gondii. Sheep and goats had seroprevalences of 19.5% (32/164) and 10.5% (29/275) respectively. In the multivariable logistic regression model, the risk of acquiring T. gondii was significantly higher in the mixed breed [Odds ratio (OR) = 71.07; 95% confidence interval (CI): 266.8-1893.1; p < 0.011)] animals than white dorper sheep and in farms that burn or bury aborted material (OR = 42.04; CI: 179.9-982.5; p = 0.020) compared to those that only burn aborted material. The risk was lower for the farms in Kagisano-Molopo (OR = 0.00; CI: 0.0-25.4; p = 0.015) and Mahikeng (OR = 0.00; CI: 0.0-4.9; p < 0.001) local municipalities than Greater Taung local municipality, and for the animals that drink water from dams (OR = 0.03; CI: 0.2–58.8; p = 0.021) than those that drink from boreholes.ConclusionThe seroprevalence and risk factors associated with transmission observed show that T. gondii infection is widespread in sheep and goats of the North West province.

Effects of adaptive duration to salinity in drinking water on behavior, weight gain and blood biochemical parameters in growing goats.

This experiment aimed to determine the effect of adaptive duration to saline water on behaviors, weight gain and blood biochemical parameters in growing goats. The experiment was arranged in a completely randomized design, which included four treatments with five animals per group. The goats were administered either fresh water (control) or seawater with a salinity of 1.5%, with varying durations of adaptation to seawater. The adaptive durations included an abrupt change (A0) from fresh water to seawater with a salinity of 1.5% or stepwise adaptation either 4 (A4) or 7 (A7) days of increasing saline concentrations. The results showed that dry matter intake in the non-adapted goats (A0 group) was lower than that of the control group or the adapted goats throughout the experiment (p<0.05). In contrast, water intake from drinking saline water was greater than that in the control group (p<0.05). Body weigh did not differ among the treatments; however, non-adapted goats exhibited a lower weight gain than the adapted goats (p<0.05). The goats in the A0 and A4 groups exhibited increased plasma levels of urea, AST, and ALT compared with the control and A7 groups. However, blood electrolyte levels remained unchanged and were within the normal range for goats. Therefore, it is concluded that the stepwise adaptation to seawater with a salinity of 1.5% for 21 days has no influence on productivity and health status of goats.

Associations between Climate Variability and Livestock Production in Botswana: A Vector Autoregression with Exogenous Variables (VARX) Analysis

The changing climate has a serious bearing on agriculture, particularly livestock production in Botswana. Therefore, studying the relationship between climate and livestock, which at present is largely missing, is necessary for the proper formulation of government policy and interventions. This is critical in promoting the adoption of relevant mitigation strategies by farmers, thereby increasing resilience. The aim of this research is to establish associations between climate variability and livestock production in Botswana at the national level. The paper employs time series data from 1970 to 2020 and the Vector Autoregression with Exogenous Variables (VARX) model for statistical analysis. The trend shows that both cattle and goat populations are decreasing. The VARX model results reveal that cattle and goat populations are negatively associated with increasing maximum temperatures. Cattle respond negatively to increased minimum temperatures as well, while goats tend to respond positively, implying that livestock species react differently to climatic conditions due to their distinct features. The results of the roots of the companion matrix for cattle and goat production meet the stability condition as all the eigenvalues lie inside the unit circle. The study recommends further intervention by the government to deal with increasing temperatures, thereby addressing the dwindling populations of goats and cattle, which have significant contributions to the household economies of smallholders and the national economy, respectively.

Relationship Polymorphism of STAT5A Gene in Performance Production of Local Goats

The study was conducted on a sample of 30 local goats in Diyala governorate / Canaan district in one of the goat breeders' fields in the region for the period from 13/11/2022 to 1/5/2022 to determine the genotype of the gene STAT5A EXON-7 and Its relationship to milk production (daily milk production-DMP and total milk production-TMP) and growth traits (birth weight-BWT, weaning weight-WWT and total weight gain-TWG). The analysis showed three-point mutations (CC=18 CT=12 C47064T AA=17 AT=13 A47088T and GG=15 GA=15 G47162A). There was no significant effect of the genotypes of the three mutations on all studied traits DMP, TMP, BWT, WWT, TWG, and body dimensions of the newborn at birth and weaning, body dimensions of the newborn at birth and weaning. Keywords: Local goats, milk production, gene STAT5A EXON-7.

КОЗЛЯТИНА: ПОЛЬЗА И ПОТЕНЦИАЛ

The purpose of research is to summarize and systematize data on the nutritional value of goat meat, benefits for human health and the potential for goat meat production. Objectives: to determine the benefits of goat meat as a source of dietary protein for human consumption; to explore the potential of goat meat production in the world. The study searched the electronic databases of Google Scholar, PubMed, ScienceDirec and Elibrary.ru, aimed at raising awareness about the goat population, emphasizing the advantages of goats over other farm animals, exploring the potential of goat meat production, as well as the benefits of goat meat for human consumption. To study the scientific literature on the problem, the method of comparative analysis was used. Goat meat is a good source of dietary protein for humans and has relatively low total fat, saturated fatty acids and cholesterol, making it a healthy food. The high concentration of iron in goat meat makes it possible to recommend this meat to pregnant women. The health-promoting chemical composition of meat meets consumer expectations for healthy eating, which explains its growing popularity and increased demand. Although goat meat is considered a lean red meat that is low in cholesterol and saturated fatty acids, some consumers mistakenly believe that goat meat is inferior in quality to beef, pork or lamb. This review aims to find evidence to support the favorable nutritional profile of goat meat and its health benefits. It is important to present goat meat as a unique product, emphasizing its na¬turalness and health benefits to consumers locally, regionally and internationally due to the animals being raised in natural conditions with very little use of pharmaceutical drugs. The hypoallergenic nature of goat meat suggests the prospects of its use in the production of baby food and as a resource in the meat industry in the production of gourmet meat products. Research is needed to improve the meat productivity of goats.

A Review on Current Scenario of Goat Population and Production in Rajasthan, India

The present assessment focuses on the goat industry in Rajasthan, with an emphasis on population and productivity. In India, the goat industry produces 1.21 million tons of goat meat (13.8%), 0.18 million tons of skins, and 6.26 million tons of milk (3%). Goats make up 50% of the total livestock population in Rajasthan and are the dominant species. As of 2019, there were 20.84 million goats in Rajasthan, which represents a 3.81% decrease from the previous census in 2012. Rajasthan produced a total of 3.10 million tons of goat milk and 95.23 thousand tons of goat meat in 2022-2023. The purpose of this review is to shed light on the current goat situation in Rajasthan and encourage entrepreneurship to establish more goat farms to improve the economic status of goat farmers in the region.

Total Replacement of Soybean Meal with Sundried Soymilk Residue in the Total Mixed Ration has a Negative Impact on Intake, Digestibility, and Milk Production in Dairy Goats.

This study aimed to evaluate whether total replacement of soybean meal (SBM) with sundried soymilk residue (SSR) in a total mixed ration (TMR) affects intake, digestibility, milk production, and blood metabolites in dairy goats. A total of 12 healthy Saanen dairy goats (40.12 ± 5.80 kg of BW) in midlactation (31.23 ± 10.12 days) were used in a randomized complete design (n = 4 goats/group). Dietary treatments were based on a TMR as follows: control TMR without SSR (CON) or SBM-based TMR with 50% or 100% of SSR replacing SBM (SSR-50 and SSR-100, respectively). All goats had ad libitum access to feed and clean water throughout the experiment. The dry matter (DM) intake decreased (p < 0.05) with the increasing replacement ratio of SBM and was lowest in the SSR-100 group. Similarly, organic matter (OM) digestibility was lowest (p < 0.05) in the SSR-100 group. However, the digestibility of DM, CP, NDF, and ADF did not change (p > 0.05) by dietary treatments. Compared with CON, the milk yield decreased significantly (p < 0.05) with increasing replacement ratio of SBM. In contrast, milk composition such as total solids, solids-not-fat, milk fat, lactose, protein, and pH were not influenced (p > 0.05) by feeding dietary SSR. Compared with other treatments, blood glucose concentration was lower (p < 0.05) in the SSR-100 group. In contrast, packed cell volume, glucose, and plasma urea nitrogen concentrations did not differ (p > 0.05). The results indicated that SSR could replace SBM in a TMR at less than 50%. Thus, the present study provides support for further investigation to enhance the utilization of soybean waste as an alternative protein source in the TMR for dairy goats and potentially other ruminants.

Gonadotropin supplementation improved in vitro developmental capacity of Egyptian goat oocytes by modulating mitochondrial distribution and utilization

Goat production in Mediterranean countries is economically and socially significant. The study investigated the impact of hCG supplementation on the in vitro maturation, fertilization, and mitochondrial activity of goat oocytes. In total, 2356 good cumulus-oocyte complexes (COCs) were recovered from 476 freshly collected goat ovaries. Selected oocytes were incubated in IVM medium and supplemented with hCG at varying concentrations depending on the experimental group for 24 hours at 38.5 ° C, 5% CO2 and 95% humidity. The first group (G1) was allocated as a control group, while the G2 and G3 groups were supplemented with 10 and 20 IU/mL hCG, respectively. The maturation rate was calculated using Hoechst 33342 staining in addition to cumulus expansion and the first polar body extrusion rates. The fertilization rate was evaluated. Moreover, mitochondrial activity was assessed using Mito-Tracker fluorescent staining. The results indicated a higher rate (P≤0.05) of nuclear maturation in G3 (82.5%) than in G2 (65.9%) and the control group (64.8%). Furthermore, fertilization rate was significantly improved in G3 (18.7%) compared to G2 (10.6%) and the control group (9.5%). Notably, the percentage of diffuse patterns of mitochondrial distribution increased in G3 (73.3%) compared to G2 (13.3%) and the control group (6.7%). In the same trend, the fluorescent mitochondrial intensity was higher in G3 (95%) and G2 (89.2%) compared to the control group (79.9%). In conclusion, supplementing the IVM medium with 20 IU/mL of hCG improved goat oocytes' maturation and fertilization rates by modulating cytoplasmic distribution and promoting the utilization of oocyte mitochondria.

Evaluation of the effect of therapeutic durations on small ruminant bacterial pneumonia

BackgroundSheep and goat production in Ethiopia is hindered by numerous substandard production systems and various diseases. Respiratory disease complexes (RDC) pose a significant threat to the productivity of these animals. Pneumonia is a common manifestation of respiratory disease complexes and often necessitates a prolonged course of antibiotic treatment. This study aimed to optimize and propose the ideal duration of therapy for pneumonia in sheep and goats.MethodsThe study was conducted from February to June 2021 at the Veterinary Teaching Hospital of the College of Veterinary Medicine and Agriculture, Addis Ababa University. The study recruited 54 sheep and goats presented to the hospital for treatment with a confirmed RDC as determined based on clinical signs and bacteriological methods. The animals were randomly allocated to 5 groups each group receiving 10% oxytetracycline (Phenxyl, Phenix, Belgum) intramuscularly for a duration of 3, 4, 5, 6 and 7 consecutive days. The treatment outcomes were assessed by recording vital signs (body temperature, respiratory rate, heart rate, coughing, and nasal discharges), performing lung ultrasonography (L-USG) as well as collection of nasal swabs for bacterial isolation and molecular identification before and after completion of the treatment. An ordered logistic regression model with random effects was employed to determine the optimal therapeutic duration, taking into account the cumulative scores of the outcome variables across the different groups.ResultsAmong the 54 sheep and goats treated with 10% oxytetracycline, a total of 74.07% (95% CI, 60.35–85.04) achieved complete recovery, as confirmed through clinical, ultrasound, and bacteriological methods. In Group 1 (G1), out of 12 sheep and goats, 8 (83.0%) recovered completely; in Group 2 (G2), out of 11 animals, 9 (82.0%) recovered completely; in Group 3 (G3), out of 11 animals, 10 (93.0%) recovered completely; in Group 4 (G4), out of 9 animals, 9 (100.0%) recovered completely; and in Group 5 (G5), out of 11 animals, 10 (91.0%) recovered completely. Bacteriological examination of nasal swabs indicated involvement of M. hemolytica in 27 (50.00%) and P. multocida in 13 (24.07%) of pneumonic animals. Detection of specific marker genes confirmed only five of the presumptive M. hemolytica isolates, whilst no isolates tested positive for P. multocida. Post-treatment samples collected from recovered animals did not yield any M. hemolytica nor P. multocida. Based on results from clinical signs, L-USG, and bacterial infection variables, the group of sheep and goats treated for seven consecutive days (G5) showed the highest recovery score compared to the other groups, and there was a statistically significant difference (coefficient (β) = − 2.296, p = 0.021) in variable score between G5 and G1. These findings suggest that the administration of 10% oxytetracycline for a full course of seven consecutive days resulted in symptomatic and clinical recovery rates from respiratory disease in sheep and goats.

Analysis of consumption preference of goat products in different regions of Mexico

Objective: To characterize and determine the consumption preferences for goat products in different regions of Mexico. Design/methodology/approach: An exploratory study was carried out through a survey addressed to 300 consumers. The sample was obtained through convenience sampling. The semi-structured questionnaire was divided into the following sections: sociodemographic information, willingness to consume, type of derivative products known, and frequency of consumption. The Kruskal-Wallis test was applied to determine significant variables. Results: It was found that milk, cheese, and meat are the most relevant foods for goat consumption. These products are ideal for expanding the diversification of consumption in Mexican regions. Limitations on study/implications: To deepen the analysis of the sociodemographic and consumption characteristics, it is necessary to consider a greater number of variables. Findings/conclusions: Knowing the products that are consumed most frequently allows more effective and efficient strategies to be generated and, in turn, opens the pattern for consumption diversification.

Cactus species and tree forage hay in the diet of dairy goats.

The purpose of this study was to evaluate the influence of the association of Opuntia stricta (OS) or Nopalea cochenillifera (NC) with Moringa hay (MY) or Leucaena hay (LY) on nutrient intake, ingestive behavior, serum biochemistry, and milk production and composition of dairy goat. Eight multiparous Saanen goats were used, with an average of 68 ± 8 days in milk and 48.5 ± 6kg of initial weight, fed with the following treatment diets: OS + MY; OS + LY; NC + MY, and NC + LY. The treatments were distributed in a double Latin square, in a 2 × 2 factorial scheme (two varieties of cactus and two of hay). Goats fed with NC had higher (P < 0.05) intakes of dry matter, crude protein, neutral detergent fiber (NDF), and non-fibrous carbohydrates. There was no influence (P > 0.05) on milk production, but goats fed with OS produced milk with higher (P < 0.05) fat content and presented higher (P < 0.05) feed efficiency. There was no effect (P > 0.05) of the hay type on the nutrient intake and milk production and composition of goats, but the animals fed with MY had higher (P < 0.05) serum cholesterol levels and greater efficiency of NDF rumination. Goats fed with OS showed greater feeding and rumination efficiency. Our results indicated that both cactus species could be successfully included in the diet of low yielding dairy goats fed 18.4% concentrate.

Relevance of Individual Data When Assessing the Gastrointestinal Nematode Infection Level, Nutritional and Productive Variables in a Tropical Farm Context: The Median Isn't the Message.

We evaluated the relationship between individual and herd GIN infection level, nutrition, production performance and anemia parameters in a tropical farm context. Fifty-four female goats were monitored to assess their body condition score (BCS, nutritional status indicator), live weight (LW) and LW gain (LWG, both used as production level indicators), FAMACHA© and hematocrit (HT, both used as anemia indicators). Goats browsed for 4 h in a tropical forest and received balanced feed and chopped grass. The eggs per gram of feces (EPG) indicated the GIN burden, with fecal samples obtained at 7:00 (AM) and 15:00 h (PM.) from each goat at six sampling points during the study. The variables and their relationship with GIN burdens were analyzed using Kruskall-Wallis, ANOVA and Friedman tests and Spearman correlations. The fecal samples obtained in the AM and PM can be equally representative of parasitic burdens (similar and highly correlated). However, the EPG of individual goats from periods of 30 days apart can be considered independent. The BCS and LWG varied between sampling times (p < 0.05), whereas EPG, LW and HT did not (p > 0.05). The GIN burden was negatively correlated with HT and BCS (-0.21, p = 0.01 for each one). The individual pattern of infection demonstrates the true impact of GINs on their hosts. Additionally, feeding and nutritional status may present important variations influencing the performance of the goats more than the impact of GINs under the farm conditions of the present study. However, GIN infection contributed to the variation in goat health and productivity in this tropical farm.
