Agro-industrial wastes pose great economic and environmental hazards, while the economic success of aquaculture is threatened by the unsustainability of fishmeal use. The aims of the present study were to bio-convert agro-industrial wastes through vermicomposting, and then evaluate the potential of the by-products in promoting aquaculture nutrition. Coffee husks (CH), barley wastes (BW), and kitchen wastes (KW) were pre-composted and inoculated with earthworms, Eisenia fetida, and then vermicomposted for 70 days under a controlled environment. The vermicomposting by-products, i.e., earthworms and vermicast, were amalgamated in the ratio of 1:5 into bedding and then analyzed. There were neither earthworm mortalities nor significant difference (P>0.05) in cocoons produced by E. fetid in all treatments. The earthworms grown in KW attained the highest average weight gain of 27.8±0.7g, followed by CH (24.9±0.6g) and BW (24.8±0.7g). Earthworms grown in CH and BW had significantly higher (P<0.05) nutritional attributes. All experimental wastes produced vermicast with carbon and nitrogen ratios within the preferred agronomic limit of 20. The nutritional profile of the BW bedding was comparable with that of Caridina nilotica meal and was within the recommended dietary requirements of fish. The wastes can be bio-converted through vermicomposting into various forms appropriate for providing aquaculture nutrition.

An experiment was conducted to determine the effects of using Avocado seed meal (ASM) as a feed ingredient in broiler chickens feed. One hundred and twenty (120), one day-old cobb breed of broiler chickens were used. There were four (4) experimental diets with diet 1 (T1) serving as the control treatment with no inclusion of avocado seed meal (0.00). Diets 2,3 and 4 contained 0.50,1.00 and 1.50% inclusion of ASM, respectively. The experiment was arranged in a completely randomized design (CRD) with three (3) replicates per treatment. Each treatment had 30 birds with 10 birds per replicate. There were significant (P<0.05) differences in final weight and average weight gain as T2 with 0.50% inclusion of ASM was significantly (P<0.05) higher for final weight (1338.33) and average weight gain (1290.33) than other treatments. While final weight (973.30) and average weight gain (925.33) in T4 with 1.50% inclusion of ASM was significantly lower. There was no significant difference among initial weight, feed intake and FCR. Among all the biochemical parameters observed, only magnesium and urea were significantly different. Mg content was significantly higher in T4 (32.33) and the least was observed in T1 (1.80) while urea content was significantly higher in T1 (1.80) and the least was observed in T3 (1.03). From the performance parameters that was obtained, it was recommended that 0.50% of ASM should be used for broiler production in terms of body weight.

The effects of the population density of adult African, giant land snail, Archachatina marginata on the egg-laying capacity and the growth of the brooders and hatchlings were investigated for 9 months. Ten culture pens were stocked with snails at 20%, 40%, 50%, 80% and 100% capacity with each group in 2 replicates. Average weight gain of brooders was highest in pens stocked at 40% population density while the lowest was in pen stocked at 100%. Average number of eggs laid per snail and average number of eggs per pen followed the same trend in the study. The highest average number of eggs laid per pen was obtained in pens stocked at 60% population density (586) while the least was from pens at 20% population density. The result was the same for the average number of eggs laid per snail i.e. 7.5 eggs in pens stocked at 60% and 4.1 eggs in pens stocked at 20%. There was no significant difference in the weights of hatchlings in the different pens.

Introduction:  Malnutrition is a pathological state of deficiency or excess of nutrients. Under-nutrition indicates a state wherein the weight for age, height for age, and weight for height indices are below-2 Z-score of the National Centre for Health Statistics (NCHS) norms. In children aged <5 years under nutrition is one of the most common causes of morbidity and mortality. There is significant increase in the risk of case fatality rate in severe acute malnutrition (SAM) children suffering from diarrhoea, measles, and pneumonia. Revised estimates with the use of the new WHO Child Growth Standards in developing country situations has resulted in a 2–4 times increase in the number of infants and children falling below-three standard deviation (3SD) weight for height/length as compared to that of using the former NCHS reference. Material and Methods:  The study was conducted on sample size of 100 children and were then followed up for the period of 2 months to assess the nutritional status during the period of initial stay and the entire follow-up period using available records of anthropometric indicators of the admitted children recruited in the study at the Nutrition Rehabilitation Center (NRC). Weight at admission and discharge and daily weights were recorded from the NRC registers; average weight gain was calculated. Results: A total of 100 patients were included in the study of which 54 (54%) were girls and 46 (46%) were boys. The mean age duration for the entire group was 26.45 ± 12.23 months; for boys 25.87 ± 12.54 months and for girls 23.66 ± 12.88 months. 51% of the parents of the admitted children were illiterate, 48% had received education up to primary school, and 1% of the parents were graduates. 49% of the parents of the admitted children were daily wage labourers, while 36% of the mothers were housewives. The average weight gain for the study group during their stay at the centers was 9.34 ± 4.33 g/kg/day; for boys the average weight gain being 8.11 ± 5.27 g/kg/day and for girls 10.29 ± 5.99 g/kg/day. The mean MUAC at admission was 11.38 ± 0.96 cm and at discharge it was 11.99 ± 1.68 cm. The difference was observed to be statistically significant (P<0.001). Dropout rates of 10%, 32%, 48%, and 70% were obtained for the four follow-up visits conducted 15 days, 30days, 45  days , and 60 days from the day of discharge. Conclusion: Children belonging to illiterate mothers have the highest rates of malnutrition. There was a significant difference between mean weight at discharge and the mean weight at admission for the entire study group which is really satisfying the need of NRC.

Na ovinocultura há a necessidade de se adaptar às novas tecnologias para obtenção de produtos com qualidade cada vez melhor. Os probióticos são suplementos alimentares contendo micro-organismos ruminais e intestinais viáveis que, em quantidade adequada, produzem efeitos benéficos na saúde dos pequenos ruminantes. O objetivo do trabalho foi avaliar o desempenho e parâmetro ruminal, através do uso de probiótico, em borregas mestiças Dorper suplementadas a pasto. Foram utilizadas 57 borregas mestiças Dorper, com idade entre 6 a 12 meses, sendo separadas em dois grupos: GC (grupo controle), com 28 animais, e GT (grupo tratado), com 29 borregas. Todos permaneceram em dois piquetes contendo capim-estrela e capim Aruana, sendo que houve revezamento semanalmente entre os grupos para cada pastagem. Uma vez ao dia, os dois grupos receberam concentrado energético-proteico equivalente a 1,5% de peso vivo por animal, disponibilizada em cochos, e somente o GT recebeu probiótico em pó na quantidade de 5g por animal, misturado à ração. Realizou-se análise bromatológica dos pastos e concentrado. No dia inicial (D0) e final do experimento (D45), foi feita classificação do escore corporal. Os animais foram pesados no dia inicial (D0), dia 7 (D7), dia 15 (D15), dia 30 (D30) e no dia último dia (D45), obtendo-se o ganho médio de peso diário (GMPD) e o peso médio. Avaliou-se o suco ruminal no último dia do experimento (D45). Não houve diferença significativa no desempenho entre os grupos, entretanto, o parâmetro ruminal demonstrou resultados superiores no grupo tratado. Palavras-chave: Escore Corporal. Ganho de Peso Médio. Liquido Ruminal. Saccharomyces cerevisiaeAbstractIn sheep farming, farmers need to adapt to the new technologies to obtain better quality products. Probiotics are dietary supplements containing viable ruminal and intestinal microorganisms, which in adequate amount can produce beneficial effects on the small ruminants health. The aim of the study was to evaluate the permormance and ruminal parameter by probiotic use in crossbred Dorper lambs supplemented to pasture. 57 crossbreed Dorper lambs were used, aged 6 to 12 months and they were separated into two groups: GC (control group), with 28 animals, and TC (treated group) with 29 lambs. They remained in Cynodon plectostachyus and Panicum maximum cv. Aruana piquet and there was a weekly relay between groups for each pasture. Once a day both groups received concentrate equivalent to 1.5% of live weight per animal, available in troughs and only the GC received probiotic in the amount of 5g per animal, mixed with feed. A bromatological analysis of the pasture and concentrate was made. On the initial day (D0) and on the end of the experiment (D45), the body score was made in all animals. They were weighed on the initial day (D0), day 7 (D7), day 15 (D15), day 30 (D30) and on the last day of experiment (D45). The average weight gain and the mean weight were performed on all days of the experiment . The ruminal fluid was evaluated on the last day of the experiment (D45). There was no significant difference in performance between the groups and the ruminal parameter showed superior results in the treated group.Keywords: Body Score.

Abstract This study aims to improve the production performance of Murrah buffalo which covers average weight gain, feed consumption, and feed conversion by increasing probiotic feed. The research was conducted on the herd of Murrah buffalo at Kelok Rambai, Kapau Village, West Sumatera, Indonesia. Fifteen Murrah buffaloes with three to five years of age were used in the research. There were three treatments conducted including P1 = basal feed + probiotics; P2 = P1 + concentrate (cassava leaf pellet); and P3 = P1 + commercial concentrate (pellet). All three treatments were also given 7 cc/head/month of probiotics. The results of the study with probiotic feeding on Murrah buffalo showed the average feed consumption of P2 (36.55), P3 (35.99), P1 (35.74) and daily weight gain (DWG) P2 (1.09 kg/head/day), P3 (0.91 kg/head/day), P1 (0.55 kg/head/day) did not show a significant difference, while in feed conversion, P2 (0.68 ), P1 (0.46), P3 (0. 31) it showed a significant difference (p>0.05). This study concludes that the provision of basal ration plus cassava leaf pellets showed significant results on feed conversion in Murrah buffalo but did not show significant differences in feed consumption and DWG. However, it showed a substantial enough average of P2 that could be used as a feed supplement in Murrah buffalo.

Background: The study of the zootechnical performance of Tilapia cabrae and Oreochromis schwebischi was carried out at the Mbolet fish farm in Lambaréné in Gabon in order to evaluate the growth and reproductive performance of these two species. Methods: For this purpose, 226 fish (113 of T. cabrae with an average weight of 30.55±9.5 g and 113 O. schwebischi with an average weight of 20.64±10.5 g), were distributed in four 6 m2 tanks with two replicates per species for the growing phase which lasted 60 days. For the reproductive phase, 42 selected mature fish, including 6 males and 36 females of each species, were placed in six 2 m2 ponds with three replicates per species for 78 days. Result: The survival rate, the number of reproductions per species and the absolute, relative and system productivities were determined. It was found that the average weight gain, daily individual growth and specific growth rate were significantly (p less than 0.05) higher in T. cabrae, 48.1±5.51 g, 0.8±0.092 g/day and 1.57±0.066% g/day respectively, than in O. schwebischi, 27.11±9.23 g, 0.45±0.15 g/day and 1.38±0.051% g/day respectively. At the end of reproduction, the absolute productivity of T. cabrae (234.75±24.71 larvae/female/egg-laying) was significantly higher (p less than 0.05) than that of O. schwebichi (104.68±46.64 larvae/female/laying). System productivity was significantly higher (p less than 0.05) in O. schwebichi (11.34±2.29 larvae/m2/day) compared to that of T. cabrae (4.12±1.73 larvae/m2/day). Thus, on a fish farm, the use of these species may be possible.

<p>The aim of this study was to evaluate and compare the performance of Brangus calves at weaning under grazing conditions, and determine the influence of the sex on its performance. This study was conducted in the Cartago municipality (Colombia), in a herd dedicated to the production of beef with Brangus breed. The data were analyzed by ANOVA with a 95% significance using the statistical software InfoStat 2015. Full records of second lactation cows that were served by the same bull were evaluated to reduce the error factor. The variables evaluated were: weight at birth, weight at weaning, meat production index and average daily gain (ADG). The following model of age at weaning was considered as a covariate: Yij=u+Ti+BXij+Eij. The weight at birth was 33.22±1.86 and 31.88±0.89 kg for males and females respectively, weight at weaning was 246.00±51.69 and 225.81±21.78 kg respectively, rate of production was 0.64±0.12 and 0.62±0.05% respectively, ADG was 890±280; 850±100 grams/day respectively, and age at weaning of 251.78±44.01 and 228.19±16.30 days respectively. Only statistical significant difference for weight at birth (p=0.0286) was observed. In conclusion, both males and females Brangus showed differences in birth weight; however, differences in meat production levels are not significant since these reach at weaning similar weight, meat production index and average weight gain. In this sense, the productive trend may be similar at post-weaning stage, being feasible to employ both males and females interchangeably for the production of beef; additionally, the heifers can arrive faster at age for bull service.</p>

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.

Aim. To optimize the methane digestion process while using different recipes of substrate components of ag- ricultural origin. Methods. The chemical composition of separate components of the substrate of agricultural by-products, industrial wastes, fats of the agrorefi nery and corn silage was studied. Dry (organic) mass, crude protein (fat) fi ber, loose ash, nitrogen-free exhaust were estimated in the components and the productivity of biogas was determined along with the methane content. These data were used as a basis for daily recipes of the substrate and the analysis of biogas production at the biogas station in Kostkowice. Results. The application of by-products of agricultural production solves the problem of their storage on boards and in open containers, which reduces investment costs, related to the installation of units for their storage. Conclusions. The return on investment for obtaining electric energy out of agricultural biogas depends considerably on the kind of the substrate used and on technological and market conditions.

The blood profile and histology of selected tissues (kidney, lungs, intestine, and epididymis) of Balami Sheep fed Shea Cake meal supplement was investigated. A total of thirty-two (32) sheep of the average weight range of 11.75-14.75kg comprising an equal number (16) of males and females were randomly allotted to four dietary treatments in a completely randomized experimental design with eight sheep per treatment for twelve weeks duration. Treatment 1 (T1) was a control diet and had zero inclusion level of Shea cake meal (SCM), while treatments 2,3, and 4 had 10%,15%, and 20%  inclusion of SCM, respectively. At the twelfth week of the experiment, two blood samples of 5ml each were taken from each animal from the jugular vein. The first set was preserved in Ethylene Diamine Tetra Acetic Acid (EDTA) bottle for haematological parameters, while the second samples were preserved without EDTA for serum examination. Representative samples of tissues were randomly selected and slaughtered for gross microscopic examination. There was a significant difference (P<0.05) at various levels of inclusion for parameters investigated. The white blood cell (WBC), Red blood cell (RBC), and Packed cell volume (PCV) recorded the highest values at T3 (15% inclusion level) (13.42 x109/L), 2.92x1012/L, 3.75%, respectively). The serum parameters were significantly(p <0.05)different among the treatments. Total protein ranges from 54.78(mg/dl) (T1) - 60.51(mg/dl) (T2), Cholesterol70.15(mg/dl) (T1) - 78.00(mg/dl) (T4). Iron ranges from 58.15(ug/dl) (T1) - 62.88(ug/dl) (T3).The histopathology of tissues (kidney, lungs, intestine, and epididymis) showed no alteration across the treatments (P= .05) in the gross microscopic examinations. No lesion was observed in the lungs, kidney, epididymis, and intestine. The results showed that shea cake meal posed no health risk to Balami sheep and as such recommended as a good supplement in the diets of the sheep.
