Mục tiêu của nghiên cứu nhằm cung cấp thông tin về đánh giá ảnh hưởng của việc sử dụng phụ phẩm thân lá gai làm thức ăn cho bò tại Quảng Ngãi. Giống cây gai xanh AP1 được thu hoạch lúc 50 - 54 ngày tái sinh sau lứa cắt thứ nhất. Cây sau khi thu hoạch được chia thành các bộ phận gồm lá, thân, rễ đem sấy khô ở 600C để phân tích thành phần hoá học. Đồng thời, phụ phẩm thân và ngọn lá được phơi khô nghiền bột hoặc được ủ chua để thực hiện thí nghiệm nuôi dưỡng trên bò. Thí nghiệm thực hiện trên 15 bò lai BBB (BBB x Lai Brahman) bố trí vào 03 nghiệm thức, 5 bò/nghiệm thức. Nghiệm thức 1 (NT1) bò được ăn thức ăn theo hiện trạng trong nông hộ, nghiệm thức 2 (NT2) ngoài thức ăn của nông hộ cho ăn thêm 0,3% khối lượng cơ thể (theo vật chất khô) bột thân lá gai, nghiệm thức 3 (NT3) ngoài thức ăn của nông hộ cho bò ăn thêm 0,3% khối lượng cơ thể thân lá gai ủ chua. Kết quả nghiên cứu cho thấy, các bộ phận khác nhau của cây gai xanh có thành phần hoá học khác nhau. Bò cho ăn thêm bột thân lá gai và thân lá gai ủ chua đã làm tăng lượng ăn vào, tuy nhiên, tăng khối lượng của bò không có sự sai khác thống kê giữa bò có cho ăn thêm bột thân lá gai cũng như cho ăn thêm thân lá gai ủ chua so với bò nuôi theo hiện trạng. Với kết quả nghiên cứu này, có thể kết luận rằng phụ phẩm thân lá gai có thể sử dụng làm thức ăn cho bò. ABSTRACT The objective of this study was to provide the information of the using AP1 ramie foliage in the diet on performance of beef cattle in Quảng Ngãi province. AP1 ramies were harvested at 50-54 days after the first cutting, the harvested ramie were divided into parts including leaves, stems and roots, and these parts were dried at 60oC then to chemistry composition analysis. The by-products of foliage were made to powder of ramie foliage and foliage silage for cattle feeding. Total 15 BBB crossbred (BBB x Brahman) were carried out by using complete randomized design, with 3 treatments (5 cattle/treatment). The first treatment, the cattle were fed the feed in household (based diet); the second treatment, based diet plus ramie foliage powder at 0.3% of BW (DM basis), and the third treatment we based diet plus ramie foliage silage at 0.3% of BW. The results showed that the difference of leaves, stems and roots, and by-product from the leaves and stems were different nutritional composition. Feed intake of cattle improved when supplementation ramie foliage powder or foliage silage (P<0.05). However, average daily weight gain of cattle was not significantly different (P>0.05). With these results, it could be concluded that the ramie (Boehmeria nivea L.) foliage should be considered and used for cattle feeding.

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, growing, and end periods, the effects of peppermint powder on average daily weight gain, feed conversation ratio, and mortality rate were studied. The results of the present study showed that over a production period of 42 days peppermint had a significant effect on average daily weight gain and feed conversation ratio when compared with the control group ( P < .05). The level of 4.5 g/kg had the highest average daily weight gain (52.78 g), and control treatment with 46.98 g had the least average daily weight gain among different levels of peppermint. The level of 4.5 g/kg and 6 g/kg of peppermint had the least mortality compared to control treatment during training period ( P < .05). From this experiment, we can conclude that treatment with 4.5 g/kg peppermint powder has better performance and carcass characteristics in broilers.

Effect of consuming solely poultry-by-products by grower pigs, instead of conventional feeds was the focus of this study. Thirty–six Large White male pigs of 6 weeks 5.7 – 7.5kg were fed Boiled Dead Birds (BDB) (T3), Boiled Hatchery Waste BHW (T2) and conventional pig food PKC (T1). Thus, there were three treatments with 12 pigs per treatment. The pigs were reared for 10 weeks over which the chemical composition, performance and digestibility studies, carcass and organ function, serum and haematological status, and physico – chemical analysis and palatability were evaluated. The study was arranged as a completely randomized design. Daily weight gain, daily feed intake and body weight gain had highest (P<0.05) values of 107.45g. 105.31g and 4513.00g inT1 compared to T2 (37.52g, 63.39g and 1580.00g) and T3 (60.00g, 63.30g and 2520.00g) respectively. Pigs on T3 performed best in physico – chemical evaluation having the lowest (P<0.05) for thermal and cold shortening, cooking loss and thaw rigor but highest (P<0.05) values for water holding capacity than for T1 and T2. Lymphocyte values and white blood cell were best for T3 while T1 had highest in monophils. The T3 had lowest significant cholesterol value (106.80 mg/dL), than T2 (336.76 mg/dL) and T1 (123.88 mg/dL) while T1 did best (P<0.05) in glucose content (84.92 mg/dL), compared to T2 (60.22 md/dL) and T1 (66.63 mg/dL). The T1 had the highest palatability scores (P<0.05) for palatability status than T2 and T3. T1 performed bestin palatability scores, performance evaluation and carcass and organ characteristics, while T2 and T3 led to higher physico – chemical properties, serum and haematological parameters, which had positive significant effect on the health status of the pigs.

A 30-day experiment was conducted with 240 unsexed broiler starters to determine the effect of cocoyam tuber meal on growth and serum mineral profile. Four diets were formulated at 0%, 10%, 20% and 30% of cocoyam tuber meal. The birds were assigned the four treatment diets in a completely randomized design and replicated 3 times with 20 birds per replicate. Feed and water were supplied ad-libitum. Data were collected on average daily feed intake, average daily weight gain, feed conversion ratio and blood was sampled from each treatment group, data obtained were analysed statistically. The performance of the broiler starter birds showed significant (p<0.05) difference among the treatment groups. Average daily weight gain was improved (p<0.05) by cocoyam inclusion at 30% inclusion level. FCR of the birds in treatment groups were significantly (p<0.05) better than the control. The parameters of serum mineral profile maintained a significant (P<0.05) difference among the treatments and showed a good evidence of body structural components of the birds. These results showed that inclusion of cocoyam tuber meal had a beneficial effect on performance and structural components of broiler starters. Cocoyam tuber meal inclusion level at 30% was recommended for optimum broiler starter birds.

The majority of lamb losses occur within the first two weeks of life, with cold stress being a major cause of lamb morbidity and mortality. This study investigated the effect of insulating lamb jackets on newborn lambs. One hundred and four newborn lambs were randomly allocated by birth date to two treatment groups, (a) non-jacketed (n = 52) or (b) jacketed (n = 52), for fourteen days after birth. The live weights of lambs were recorded regularly up to 21 days, and average daily weight gains were calculated from these data. For the first two days after recruitment to the study, surface and body temperatures of lambs were also recorded. The jackets significantly increased the lambs’ surface temperatures, providing a warmer microclimate and reduced cold stress for jacketed lambs. There was no significant effect of the insulating jackets on estimated body temperatures, live weights or average daily weight gain of the lambs in this study. There were no detrimental effects of the jackets, and no rejection of lambs occurred.

A study was conducted to determine the efficacy of three most commonly used growth promoters from different pharmaceutical companies on growth performance of hybrid walking catfish (Clarias batrachus × Clarias gariepinus). The experiment was done in the wet laboratory of the Department of Aquaculture, BAU, Mymensingh, with a total of 10 aquaria and 160 fish having mean initial weight of 6.3 ± 0.48 g. The three growth promoters, “Charger gel” from Fishtech (BD) Ltd., “Growth gel” from Advance Agrotech (BD) Ltd. and “Hepaprotect-aqua” from Renata Animal health Ltd., were used in separate nine (9) aquaria at recommended, lower dose and higher dose respectively. One aquarium was used as control (diet without any growth promoter). The fish were fed with paragon nursery floating feed at 20% of body weight in each aquarium for 28 days. Doses of Charger gel were given as 80, 60 and 100 mg/20 g feed/day, that of Growth gel, 0.14, 0.12 and 0.16 ml/20 g feed/day and of Hepaprotect-aqua, 30, 15 and 50 mg/20 g feed/day. Re-circulatory system was used throughout the experimental period. By applying recommended, lower and higher dose of “Charger gel”, mean final weights were found as 23.0, 21.9 and 35.9 g; average daily weight gain as 0.60, 0.56 and 1.06 g and specific growth rate (SGR) as 2.01, 1.93 and 2.70% respectively. For “Growth gel”, mean final weights were found as 22.8, 17.3 and 31.1 g; average daily weight gain as 0.59, 0.39 and 0.88 g and SGR as 1.99, 1.57 and 2.48 % respectively. For “Hepaprotect-aqua”, mean final weights were found as 24.2, 17.5 and 28.2 g; average daily weight gain as 0.64, 0.40 and 0.78 g and SGR as 2.09, 1.58 and 2.32% respectively. In all the cases survival rates were 100%. All the three growth promoters showed better results at their higher doses in comparison to their results in lower and recommended doses. However, in average Charger gel showed the best result than the other two growth promoters. This information on the efficacy study of growth promoters needs to be disseminated to the farmers for improved fish production.Asian J. Med. Biol. Res. March 2017, 3(1): 103-108

The experiment was conducted to optimize the dose of 17?-methyl testosterone (MT) during masculinization of tilapia (Oreochromis niloticus) fry. Five treatments were designed with various doses of hormone to find out the most effective one. The treatments were designated as T1 (0 mg MT/kg), T2 (40 mg MT/kg), T3 (50 mg MT/kg), T4 (60 mg MT/kg) and T5 (70 mg MT/kg). MT was administered orally by using nursery feed and Ethanol (as hormone carrier solvents) diet to tilapia fry for 28 days in hapa. After completion of the trial period of 28 days nursing of the experimental fry was continued for further 2 months with commercial feed. At the end of experiment the sex ratio was      determined by examining gonad after dissecting the fish. Growth performance was monitored by recording the morphometric characteristics i.e. weight gain (g), average daily weight gain (g). The analysis of growth data showed significant variation in weight, % weight gain, SGR (% /day) of fish among the different treatments. SGR increases with the increase of hormone dose. The present study demonstrated that all MT receiving treatments showed a significantly (p<0.01) higher male proportion (94.28%) than control (48.57%). The dose of 60 mg MT/kg of feed resulted in maximum male population (94.28%). The result indicated that the optimum dose of MT hormone was 60 mg /kg with a feeding period of 28 days after hatching.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11052   J. Bangladesh Agril.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

This studywas carried out to determine the utilization and the optimumlevel of offer of bitter leaf (Vernonia amygdalina) meal (BLM) by West African Dwarf (WAD) goats. In a 20-week trial, twenty four WAD goats of both sexes, 5-7 months old, were randomly allotted to four treatments of graded levels of BLM(0% BLM(Control diet), 15% BLM, 30% BLMand 45% BLMdiets) in a completely randomized design to determine the utilization of bitter leafmeal as feed for goats. The dietswere used as supplements to a basal ration of Panicummaximum. Two digestibility trials were carried out. The digestible ether extract intake and digestible organic matter of goats on 0% BLM were significantly (P<0.05) higher than the values obtained for goats on bitter leaf meal diets. The average daily weight gain (g/day) for goats on 0% BML was significantly (P<0.05) higher than that of others. There were significant (P<0.05) differences in the percentage mortality of the goats fed experimental diets. The percentagemortality of goats on 30% and 45%BLMwere significantly (p<0.05) higher than that of others. It is concluded that bitter leafmeal can be included in the diets of (WAD) goats up to15%without any deleterious effect.
