Evaluation of Substitution of Noug Seed Cake with Pigeon Pea Dried Leaves as a Supplement Feed in Fattening Oxen Based on Teff Straw Basal Diet at Haik Agricultural Research Sub-Center, Ethiopia

The experiment was conducted to evaluate substitution of noug seed cake with dried pigeon pea leaves on feed intake and weight gain of local old oxen. A total of 25 local old oxen (Bos indicus) with 7-8 years old and an initial mean body weight of 300.2±19.25 kg (mean±SD) were used for the study. The experiment was carried out for 105 days including 15 days of acclimatization period. The design employed for this experiment was randomized complete block design with five replications. The dietary treatments were T1= Teff straw ad libtum +Wheat bran + Pigeon pea (25%)+ Noug seed cake(75%) ; T2= Teff straw ad libtum + Wheat bran + Pigeon pea (50%)+ Noug seed cake (50%); T3=Teff straw ad libtum + Wheat bran + Pigeon pea (75%)+ Noug seed cake(25%); T4= Teff straw ad libtum + Wheat bran +Pigeon pea (100%); T5= Teff straw ad libtum +Wheat bran + Noug seed cake (100%). The result showed that crude protein content of Pigeon pea dried leaves (24.47%), noug seed cake (31.92%) and wheat bran (15.98%) can satisfy ruminant production requirement. Total dry matter, teff straw and nutrient intake were statically highly significant (P<0.01, P<0.001, P<0.001) respectively between treatment groups but supplement intake was not statically significant (P>0.05) among treatment groups. The average total DM intakes of all treatment groups were ranged from 7.29 to 8.09 kg/d/head. There were no significant differences(P>0.05) in initial body weight gain, final body weight gain, total body weight gain and average daily body weight gain among different combinations of treatment groups. The average daily weight gain (675.56 g), gross benefit (2159.96 ETB) and marginal revenue 1.11ETB of treatment 2 was higher than other treatment groups. Therefore, it is recommended that fattening of old local oxen using supplement combination levels of teff straw+ wheat bran+ 50%pigeon pea+ 50% noug cake resulted better body weight gain and good benefit.

Protein supplements increased feed intake and enhanced growth of Yankasa sheep fed Congo grass (Brachiaria ruziziensis)

This study compared the feed intake and performance of Yankasa sheep fed Congo grass (Brachiaria ruziziensis) basal diet with different protein supplements of Cotton Seed Cake (CSC), PalmKernel Cake (PKC), Brewer'sDriedGrain (BDG) and sole B. ruziziensis grass (control). Sixteen (16) Yankasa sheep weighing between 21.63 and 22.23kg and aged about 12 months were randomly allotted to treatment diets. The total dry matter and crude protein intake were highest (P<0.05) in sheep on CSC supplement (996.33 and 118.56g) while the control diet had the least feed intake (796.4 and 57.90g).The total live weight gain (TLWG) increased (P<0.05) from 0.91kg in sheep fed Congo grass solely (control) to 2.50kg in those fed Cotton Seed Cake, while feed conversion ratio reduced from 52.50 in Congo grass to 29.15 inCSC treatment. It is concluded from this experiment that Yankasa sheep utilizedCSC better thanPKC,BDGandBrachiaria ruziziensis (control). It is therefore recommended that Brachiaria ruziziensis should be supplemented withCotton SeedCake at a rate of 250g/d for better intake and liveweight in Yankasa sheep production.

Haematological and serum biochemical indices of broiler chickens fed roselle seed meal (Hibiscus sabdariffa l.) As replacement for groundnut cake

This study was carried out to evaluate the haematological and blood biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) diet as replacement for groundnut cake (GNC). Proximate composition of the test diet and experimental diets were conducted to determine their nutrient contents. Four diets were formulated for the broiler chickens. The Diet 1 served as the control diet while diets 2, 3 and 4 contained 8%, 16% and 24% with Roselle seed cake (RSC) diets respectively as replacement for groundnut cake (GNC). A total of 120, one day-old Ross broiler chicks were randomly allotted to four dietary treatments with four replicates and each treatment consisted of 30 birds in a Completely Randomized Design (CRD). Feed and water were provided for the birds ad libitum. The blood parameters measured are haemoglobin, packed cell volume, red blood cell, white blood cell, heteropils, lymphocytes, monocytes, eosinophils, basophils and band cell. The results from the parameters measured for blood quality showed no significant (P?0.05) differences for haemoglobin level, packed cell volume (PCV), white blood cell (WBC), across the treatments. But the red blood cell (RBC), heterophils and lymphocytes had a significant difference across the dietary treatments and this implies that Roselle seed cake (RSC) inclusions in the diets of the birds had a positive effect on the oxygen carrying capacity, immunity level and antibodies producing capacity of the birds. The blood biochemical parameters measured are total protein, albumin, cholesterol, creatinine, triglycerides, HDL and LDL. The parameters measured showed no significant (P?0.05) differences in total protein (TP), creatinine, high density level (HDL) and low density level (LDL) across dietary treatment while albumin and cholesterol had significant differences (p>0.05) across the dietary treatments. RSC can replace GNC at 16% dietary inclusion levels.

Haematological and serum biochemical indices of broiler chickens fed roselle seed (Hibiscus sabdariffa l.) cake based diet as replacement for soyabean meal

Feeding trial experiment was carried out to evaluate the haematological and serum biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) as replacement of a conventional protein source. Proximate composition was done to determine the nutrient content of RSC and experimental diets. The experiment contained graded levels of RSC replacing soya bean cake (SBC). One hundred and twenty (120) day old Ross broiler chickens were used in a Completely Randomized Design (CRD). The broiler chicks were assigned to five dietary treatments with three replicates each with 8 birds per replicate and 24 birds per treatment. Five isonitrogenous and isocaloric diets were formulated for the broiler straight diet. Diet 1 served asthe control diet while diets 2, 3, 4 and 5 contained 8%, 16%, 24% and 32% RSC respectively. Data were collected and analyzed using analysis of variance and the mean was separated using Duncan multiple range test. The findings from the study showed that there were no significant (P?0.05) differences in all the parameters measured for haematology across dietary treatment means except for the white blood cell. The blood biochemical composition showed no significant (P?0.05) differences in total protein, high density lipoprotein, low density lipoprotein and creatinine across dietary treatments. RSC as an alternative feedstuff can replace soya bean cake at 24% in the diet of broiler chickens for improved haematological and blood biochemical of broilers. Roselle seed cake can replace SBC at the broiler chicken straight ration at 75% (24% dietary RSC) inclusion for better performance.

Development and Evaluation of Deoiled Seed Cake and Paddy Straw Amended Potting Media for the Cultivation of Tomato and Cucumber

The present study aimed to analyse the potential of six Deoiled cakes (DOCs) (2.5, 5, 7.5 and 10% (v/v)) and Paddy straw (PS) (10% (v/v)) as potting media (PM) amendments and its subsequent effect on the physical and nutritional properties of the PM and plant health. The study focussed on two transplantable horticulture crops, cucumber (Cucumis sativus L.) and tomato (Solanum lycopersicum L.) using coir pith (CP) and vermicompost (VC) as the base material of PM. Among 6 DOCs tested, neem (2.5%) and niger cake (5%) were found to be significant in improving the plant growth of both the crops tested. Further, PS powder amendment to selected PM improved the plant growth, up to 10% (v/v). However, at higher concentrations, PS amendment recorded decreased shoot and root length. Two optimized potting media, DPM-1 (CP + VC + Neem cake + PS:77.5 + 10 + 2.5 + 10% (v/v)) and DPM-2 (CP + VC + Niger cake + PS:75 + 10 + 5 + 10% (v/v)) were evaluated in comparison to peat-based two commercial potting media (CPM-1 and CPM-2). DPM-1 and DPM-2 recorded, bulk density (0.29 and 0.28 g/cm3), water holding capacity (59.87 and 59.02%), and % solid (16.63 and 15.37%), air porosity (23.50 and 25.61%), total porosity (83.37 and 84.63%), Ec (2.64 and 2.76 mS/cm), and pH (6.56 and 6.40), respectively. However, all these parameters were within the recommended range of ideal PM. Tomato and cucumber seedlings were grown in both DPMs showed significant improvement in growth and macro and micronutrients in comparison to CPMs and control.

The Milk Thistle Seed Cakes and Hempseed Cakes are Potential Feed for Poultry.

Simple SummaryIn accordance with Commission Regulation (EC) No 726/2004, the use of antibiotics as stimulators of animal growth and performance has been banned in all European Union countries since 2006 (due to the elimination of antibiotic residues from the human food chain). Due to this ban, many scientists are studying alternative approaches to the use of various biologically active substances with a growth-promoting effect. A promising direction is the use of alternative feeds containing bioactive compounds or mixtures of natural origin, or the use of phytoadditives or plant extracts, probiotics, prebiotics, symbiotics or oilseed by-products, such as hempseed cakes and milk thistle seed cakes, in animal nutrition.The aims of this work were to summarize the nutritional value of the milk thistle seed cakes and hempseed cakes and describe the influence on selected performance parameters, metabolism and animal health from inclusion of these non-traditional feeds into diets. It seems more appropriate to apply the extract of the bioactive substances complex to the livestock diets than addition of expellers or other forms of plants processing. The seed expellers, etc. mostly worsened the chickens’ performance parameters with higher doses in diets, while most of the work using the extract yields had positive results on animal performance.

Growth Performance of Heteroclarias Juveniles Fed Graded Levels of Autoclaved Castor Seed (Ricinus communis L.) Cake Based Diets

An 84 day feeding trial was conducted on the juveniles (42.51±0.09g) of hybrid catfish, Heteroclarias, in order to evaluate the nutritional potential of 30 minutes autoclaved castor seed cake isonitrogenous (40% crude protein) and isocaloric (3212Kcal/Kg) diets replacing soybean meal at 0, 12.5, 25, 37.5 and 50%, the diets being designated D1, D2, D3, D4 and D5 respectively. Prior to this, the castor seeds (Ricinus communis L.), ZiboCastor No. 3 variety, collected from Ado-Ekiti metropolis, Nigeria were subjected to 0, 20, 30 and 40 minutes autoclaved at 121oC, dehauled, grounded, oil extracted to form cake, then the proximate and antinutrients analysis were carried out. The preliminary tests on the seeds revealed 30 minutes level of autoclaved seeds was the best. The growth performance result showed that there were significant differences (p<0.05) in the mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and apparent net protein utilization (NPU) among the various diet levels with the progressive decline in the values of each parameter (except FCR that showed progressive increment) along the trend of increment of castor seed cake inclusion (D1, 0%; D2, 12.5%; D3, 25%; D4, 37.5% and D5, 50%). The survival rate followed the same trend of declination with the highest percentage recorded for D1 (93.33±6.67%), followed by D2 (83.33±3.33%), D3 (76.57±3.33%), D4 (66.67±3.33%) and D5 (60.00±5.77%) respectively. Hence the best growth performance and nutrient utilization was shown in D1 (control) followed by D2. It is therefore recommended that autoclaved castor seed cake at 121oC be included at not more than 12.5% inclusion level to reduce cost of feed without necessarily compromising fish growth rate.

Wilt disease management of pigeonpea caused by Fusarium oxysporum f. sp. udu of Eastern U.P.

Wilt disease (Fusarium oxysporum f. sp. udum) is one of the most destructive soil-borne diseases of Pigeon pea. Field experiments were conducted at supervision of Asha Bhagwan Bax Singh P.G. College Ayodhya, during Kharif seasons of 2017 and 2018 in the farmer's field of Ayodhya and Ambedkarnager district of Uttar Pradesh, to find out different integrated management levels of control schedule for pigeon pea wilt disease. All treatments had a significant effect on disease incidence, seed yield and disease index in both the consecutive years of experimentation. Nine Seed treatment combinations viz. T1- Trichoderma viride alone @ 12g/kg seed, T2- Thiram + Carbendazim + Trichoderma viride + Rhizobium @ 13 g /kg, T3- Thiram + Carbendazim+ Trichoderma viride + Rhizobium + Soil application of Trichoderma viride @ 10 g/kg, T4- Carbendazim 50 % WP (ST) @ 5.0 g/kg, T5- Carbendazim 25 % WP + mancozeb50 % WP (ST) @ 3.0 g/kg, T6- Neem seed cake (SA) @ 5.0q/ha.. T7- Castor seed cake (SA) @ 6.0q/ha, T8- neem seed cake (SA) + [carbendazim 25 % WP + mancozeb 50 % WP] (ST) + azoxystrobin 23 EC (SD) + Soil application of Trichoderma viride @ 20 kg / ha + 1 kg/ ha +3 g / kg seed + 12 g / kg seed +12 g and T9- untreated control were evaluated against wilt disease of pigeon pea on the popular variety Bahar. T8- neem seed cake (SA)+ carbendazim 25 % WP + mancozeb 50 % WP (ST) + azoxystrobin 23 EC (SD) + Soil application of Trichoderma viride @ 20 kg / ha + 1 kg/ ha +3 g / kg seed + 12 g / kg seed +12 g was found most effective with minimum wilt incidence 2017 and 2018 (3.40 % and 5.50 %), reduction over control (%) 93.99 & 90.86 and disease index 61.76 & 61.48 % and recorded maximum yield 2017 and 2018 (2160 and 2100 kg/ha), respectively followed by T3- Thiram + Carbendazim+ Trichoderma viride + Rhizobium + Soil application of Trichoderma viride @ 10 g/kg, 10.90 and 11.60 % wilt incidence, reduction over control (%) 80.74 & 80.73 and disease index 55.17 & 55.26 % with yield kg/ha was 1740 kg /ha and 1860 kg/ha.

Nutritional Evaluation of Roselle (Hibiscus sabdariffa L.) and its Application in Biscuit Supplementation

Roselle (Hibiscus sabdariffa L.) plant was analyzed for its chemical and nutritional characteristics of plant parts (seeds, seeds cake, leaves, stems and roots) as well as the effect of the replacement of wheat flour with roselle powder at different ratios either from roselle seeds cake (0, 10, 20 and 30%) or roselle leaves powder (0, 2.5, 5 and 7.5%) on the nutritional and quality properties of biscuits. The obtained results proved that roselle seed, cake and leaves is a rich source of valuable nutrients, i.e., protein (12.32 – 29.06%), lipids (4.45 – 27.83%), ash (5.53 – 15.13%) and crude fiber (14.52 – 20.53%) as well as higher content of essential minerals. Potassium, calcium and phosphorus are to be the highest concentration in roselle parts, it ranged between 7.94-46.30 mg/g (potassium), 5.29-28.80 mg/g (calcium) and 3.23-22.10 mg/g (phosphorus), other studied elements are at the lowest values. Total phenolic compounds ranged between 155.04-3288.33 ppm as gallic acid, so it was the highest in roselle leaves being 3288.33 ppm followed by stem (2086.78 ppm); however it could be used as natural antioxidant. In corporation of roselle cake or leaves powder in biscuit formula improved the nutritional profile and physical characteristics of biscuits. Increasing the incorporation of roselle cake or leaves powder, it increased the nutritive value of prepared biscuit. On the other hand, cocoa biscuit recorded the highest values of the physical properties than vanilla biscuit. Sensory evaluation revealed that the best replacement ratio was 10% 0f roselle cake and 2.5% of roselle leaves which gave suitable attributes for panelists which scored the highest level of biscuit quality. From the obtained results, roselle could be become an excellent economic and valuable source of the nutritional factors which can be used in food supplementation. It is worth mentioning that, roselle seeds and cake are considered a good source of protein and can replace animal protein, especially for vegetarians.

Charcoal Yield and Fixed Carbone Content of Jatropha Seed Cake Pyrolysis: Effect of Preheating Temperature, Extraction Pressure and Seed Form

The pyrolysis characteristics of cake from whole, kernels and crushed jatropha seed (Charcoal yield, fixed Carbone content, mineral matter) were assessed. The pyrolysis process consisted in introducing into an oven, at 300°C for 15 minutes, a 25 ml ceramic crucible containing 5 g of cake (2% water content) coated in pre-weighed aluminum foil. The main results were as follow. The highest charcoal yield (75,76±1,53%) was obtained with cake from crushed seeds preheated at 100°C associated to the extraction pressure of 15000 pounds. The highest fixed Carbone (18,64%) was registered with biochar from kernels cake obtained at the preheating temperature/extraction pressure couple of 25°C-15000 Pounds. The highest mineral matter content (Mg, Ca, P and K) are recorded in charcoal from the kernel cake pyrolysis. Seed form significantly affected the cake yield and biochar yield. The pH of jatropha biochar (7,5-10) are alkaline which can be useful for acid soil fertilization in Cameroon.

Effect of Feeding Different Mixtures of Short Milled Wheat and Sesame Seed Cake on Intake, Digestibility, and Live Bodyweight Changes for Abergelle Sheep in Tigray

Background: The use of agro-industrial by-products is an alternative to enhance the performance of animals. Objective: To improve feed intake, digestibility, and live bodyweight changes for Abergelle sheep fed different mixtures prepared using short milled wheat and sesame seed cake mixtures. Methods: The experiment was designed using yearling male rams and was divided into four blocks based on initial live weight and assigned to each dietary feed randomly. The diets were prepared at a level of 0, 120, 240, and 360 gram dry matter base/day for diet1, diet2, diet3, and diet4, respectively, with a proportion of 65:35 (short milled wheat: sesame seed cake) combinations. Digestibility trial was conducted for 7 consecutive days following the 90 days feeding stage. Results: Total dry matter and nutrient intake were significant (P<0.001) in the order of diet4> diet3> diet2 level of supplementation than the control group (diet1). Feed conversion efficiency and final bodyweight gain were significant (P<0.01) for the supplemented groups. Apparent digestibility of crude protein was observed highest in diet4 (81.32) and lowest in diet1 (61.55). Similarly, dry matter and organic matter digestibility were significantly higher in diet4 (74.47, 76.38) and lowest in diet1 (58.71, 60.42), respectively. In general, supplementation with different levels of sesame seed cake and short milled wheat improves the biological performance of Abergelle sheep. Conclusion: The growth performance of rams can be realized supplementing with diets prepared using short milled wheat and sesame seed cake mixtures.

Investigation on Polymer Composite Materials Wear Reinforced by Microparticles of Jatropha Curcas L. Waste

The subject of the paper is a research on the wear resistance by friction against loosely fixed abrasive particles on a polymer composite material reinforced by waste microparticles from a pressing process of Jatropha curcas L. seeds with concentration from 5 to 20 wt.%. The seed pressing waste was used in form of Whole seeds cake (WSC), Seed shells (SS) and Seed kernels cake (SKC). The waste, which is difficult to further utilize for its inability to use as feed, arises at the pressing process of Jatropha Curcas L. seeds. A matrix of composite materials was epoxy-based. The wear tests were performed by the device Tester T-07 according to GOST 23.208-79. An addition of the filler significantly increased the wear resistance by friction against a rubber wheel with loosely fixed abrasive particles of sand. The wear resistance was increased up of 69% to 82% at tested polymer composite systems against matrix (resin). Composites materials with the filler Whole seeds cake (WSC) achieved the best results.

Substituting urea by organic wastes for improving maize yield in alkaline soil

Nitrogen (N) deficiency is a very common problem of alkaline soils. Incorporation of organic residues with urea could be promising practice for improving soil properties and crop yield. This study was aimed, to evaluate the responses of two maize cultivar (Azam and Jalal) to organic wastes and Urea (sole organic residues i.e. seed cake (SC), poultry manure (PM), press mud (PrM) and mineral nitrogen (urea) and their combinations with urea (25%, 50% or 75%) applied at 150 kg N ha−1 under field conditions. Significant differences were recorded for leaf area index, plant height, number of grains ear−1, 1000 grain weight, biological and grain yield to N sources. Maize cultivar Jalal performed significantly better than Azam for all tested traits. The performance of both cultivars was significantly better when N was applied as either SC/PM with urea at 25:75, SC and PM with urea at 25:25:50, 100% sole urea, SC/PrM with urea at 50:50, or all organic N sources (25%) with urea (75%). Integration of organic wastes with urea gave the higher maize yield however, it was similar to the yield obtained from sole urea but due to allied environmental and health hazards, the sole use of urea could not be encouraged.

Durian Seed Cake As A Solution For Using Durian Seed Waste

KEJITAN (Kue Biji Durian or Durian Seed Cake) is a processed cake made from durian seed flour.

The step taken is a raw material survey, which is a survey related to the availability of raw materials for making durian seed flour. Then, a survey is carried out related to products that are sold in the market and are in demand by consumers. Then after the production phase, marketing of KEJITAN products is carried out through mass media such as Instagram, Whatsapp and direct sales to consumers around the city of Mataram. Publications through online mass media aim to introduce KEJITAN products to all groups, seeing social media users from all walks of life. The output produced by the KEJITAN business is the realization of a business in the form of processed products made from durian seed flour which has not been touched by its existence and has health and economic benefits, fostering a love for consuming processed products made from waste.Keywords: Durian, waste, flour

Slow pyrolysis of Defatted Seeds Cakes of African star apple and silk cotton for production of bio-oil

The prospect of de-oiled seed cakes of African star apple (ASA) and Silk cotton (SCS) as a source of bio-oil was investigated using slow pyrolysis. The study was carried out at a temperatures range of 300–450 °C with a heating rate of 10 °C min−1 for 60 min residence period in a nitrogen atmosphere. The optimum bio-oil yields for SCS (33.1%) and for ASA (48.3%) were achieved at 400 °C. The Bio-char yield decreases from 300 °C to 450 °C (38%–28%) for ASA seedcake which could be due to greater primary decomposition of the biomass samples. A similar trend also observed for SCS with a lowest bio-char yield of 32% at 450 °C. The GC-MS analysis showed that ASA bio-oil has an acids (25.15%), phenolics (18.35%), and hydrocarbons (18.58%) as the major compounds. N-containg compounds (38.17%), carboxylic acid (23.79%), and phenolic (16.57%) were the dominant compounds in SCS bio-oil. The FT-IR absorption peak showed at 1660 cm−1 (C = N stretching) with higher intensity for SCS bio-oil. At optimum temperature 400 °C, 72% of ASA feedstock was converted into bio-oil and gaseous products (conversion), while 68% conversion was obtained from SCS at optimum temperature 400 °C.
