Nutrient Compositions

This study evaluated the growth performances and nutrient compositions of pabda Ompok bimaculatus (Bloch, 1797) in a recirculating aquaculture system (RAS) and a closed aquaculture system (CAS). The average daily weight gain (ADG) and specific growth rate (SGR) of pabda in RAS (ADG: 0.18 g/d; SGR: 3.40 %/d) was 3.61- and 1.41-folds higher than that of the CAS (ADG: 0.05 g/d; SGR: 2.40 %/d). Fish had significantly higher level of PUFA (Poly-unsaturated fatty acid) in CAS (41%) than in RAS (33%). The ratio between omega-3 and omega-6 fatty acids in RAS and CAS were 0.73 and 0.69, respectively. This study’s results have demonstrated that the culture of pabda in RAS is more suitable than CAS in terms of growth. J. Asiat. Soc. Bangladesh, Sci. 47(1): 1-12, June 2021

This study was conducted to compare the effect of different ratio of omega-3:omega-6 in total mix ration to blood metabolites and reproductive performance of ewes. A total of 25 young ewes were randomly assigned to five experimental groups and five replications : R0 (without omega-3:omega-6), R1 (omega-3:omega-6 1:8), R2 (omega-3:omega-6 1:6), R3 (omega-3:omega-6 1:3), R4 (omega-3:omega-6 1:2). The parameters measured were feed intake, productive performance, blood glucose and cholesterol pre-mating period. Parameters of characteristic estrous measured were onset of estrous, length of estrous and estrous response. The result showed that ratio of omega-3 and omega-6 1:2 have a greatest daily weight gain and feed efficiency. Ratio of omega-3 and omega-6 1:2 have blood glucose lowest, but highest blood cholesterol. Addition of omega-3 cause to delays onset of estrous. The conclusion is greatest length of estrous, estrous response and pregnacy rate on ratio of omega-3 and omega-6 1:2 in ration.

Experiment was conducted to evaluate the high density culture of Mystus cavasius and its effects on growth performances, survival rate and proximate composition of the fish in recirculating aquaculture system. Fishes were cultured at 571, 714, 857 and 1000 fries/m3 as the initial stocking density. No significant differences (p > 0.05) were found in specific growth rate, average daily gain, food conversation ratio, protein efficiency ratio, condition factor (k) and survival rate (%) of fish under the culture period of 120 days among the different stocking densities. The average survival rate was ≥ 99% among the treatments at the end of the culture period. The moisture contents were between 77.10 and 77.75%, ash content was 2.58 and 2.61%, crude protein was 15.86 and 16.07%, crude lipid was 5.45 and 5.68% with no significant differences (p > 0.05) among the treatments. There were no significant variations in DO, TAN, NO3-N, NO2-N and pH among the treatments during culture. This study showed that stocking density of at least 1000 fries/m3 was the best option as the total gain was highest compared to other lower densities under similar facilities. Dhaka Univ. J. Biol.

The effects of five levels of aflatoxin B1 (0, 25, 50, 100 and 200 ppb) and three (15, 30 and 45 days) culture durations on the growth performances and residue concentration in Thai koi, Anabas testudineus was investigated in indoor plastic tanks. Significant differences were found in 100 and 200 ppb treatment groups in average daily weight gain (ADG, g/d) and specific growth rate (SGR, %/d) compared to those of control, 25 and 50 ppb treatments group. Body muscle in 200 ppb treatment group had significantly higher concentration of aflatoxin B1 (AFB) residue than in the 100 and 50 ppb treatments. Control and 25 ppb treatments group did not have any residue. Total protein and fat contents decreased compared to control, 25 and 50 ppb treatments group. The results suggested that the level of contamination by 50, 100 and 200 ppb aflatoxin B1 in the feed of Thai koi fingerlings may concentrate in the body muscle at a level of above human health hazards. Any feeds with even 50 ppb AFB1 should not be used as feed for raising food fishes. Dhaka Univ. J. Biol. Sci. 28(1): 37-47, 2019 (January)

Um fator diferencial na produção de bovinos é a compreensão da contribuição individual dos ácidos graxos e do papel dos lipídeos nos ruminantes, tanto na forma de análise (ácido graxo ou extrato etéreo), conceitos relacionados às características de ômega 3, ômega 6 e ácido linoleico conjugado na bio-hidrogenação, no metabolismo pós-absorção, bem como no conteúdo e composição dos ácidos graxos em relação à matéria seca dos alimentos. Sabe-se que diversos fatores podem afetar o teor, digestibilidade e degradabilidade das fibras presente na forragem, e o mesmo ocorre com os lipídeos. As diferenças entre os valores dos compostos presentes nos lipídeos podem ocorrer dependendo do ambiente, região do país ou fase de colheita e por isso, torna-se importante obter a análise da composição de ácidos graxos dos alimentos lipídicos, para que dessa maneira seja possível otimizar a utilização deste nutriente na dieta de animais ruminantes. Sendo assim, a proposta dessa revisão será trazer a discussão sobre o tema e abordar um entendimento sobre o conteúdo e composição de ácidos graxos dos ingredientes que compõem a dieta dos animais ruminantes, com ênfase na influência exercida no desempenho produtivo, imunonutrição, e no produto final (carne ou leite).
