“…Yan & Qiu (1998) reported that the highest SGR was observed for O. nilotica (initial body weight: 5 g) fed the diets containing 8 and 10 g kg −1 betaine, and the lowest FCR at the betaine level of 8 g kg −1 . Kasper et al. (2002) also reported that addition of 5 g kg −1 betaine to tilapia diet led to a significant increase in feed consumption.…”

An 8‐week feeding experiment was conducted to determine the effect of dietary betaine levels on the growth performance and hepatic intermediary metabolism of genetically improved farmed tilapia (GIFT) strain of Nile tilapia Oreochromis niloticus (mean initial body weight: 78.3 ± 1.3 g, means ± SD). Six practical diets were formulated with the incorporation of betaine at the levels of 0 (control), 5, 10, 15, 20 and 25 g kg−1. Survival showed no significant differences among the treatments (P > 0.05). The highest and lowest weight gain (WG) and specific growth rate (SGR) were observed for fish fed the diets containing 5 and 0 g kg−1 (control) betaine, respectively. Feed intake showed similar trend with WG and SGR. In contrast, feed conversion ratio was the lowest when dietary betaine level was 5 g kg−1. In general, dietary betaine supplementation showed no significant effect on hepatic composition of tilapia. Condition factor and viscerosomatic index tended to increase with increasing dietary betaine levels from 0 to 5 g kg−1 and then decline when dietary betaine levels further increased from 5 to 25 g kg−1. In contrast, hepatosomatic index declined with increasing dietary betaine levels (P < 0.05). Dietary betaine levels significantly influenced several hepatic enzymatic activities, including succinate dehydrogenase, lactate dehydrogenase, malic dehydrogenase, lipoprotein lipase and hepatic lipase, suggesting that dietary betaine addition had significant effects on nutrient metabolism in the liver. Based on the second‐order polynomial regression analysis of WG, 12.5 g kg−1 of dietary betaine level seemed optimal for genetically improved farmed tilapia strain of O. niloticus.

“…Generally, the addition of betaine to fish diets increased feed consumption, while the addition of betaine in the presence of choline (c+b) led to the best growth performance, FCR and PER. Kasper et al . (2002) reported that addition of 0.5% betain to tilapia diet led to a significant increase in feed consumption.…”

“…The aquaria were aerated by air pump to supply the oxygen needed. Basal diets A (31% CP; according to tilapia requirement NRC 1993) and B (24% CP; according to tilapia minimum balance amino acid requirement NRC 1993) were supplemented with 0.3% choline chloride to cover tilapia requirement for choline according to (Kasper, White & Brown 2002). Diets A c+b and B c+b were supplied with 0.3% choline and betaine 0.5% according to (Xue & Cuir 2001).…”

Effect of mixed protein schedules combined with choline and betaine on the growth performance of Nile tilapia (Oreochromis niloticus)

Reducing feed cost has been a major issue in fish nutrition. Mixed protein schedules have been proposed as one of the methods successfully tested in many fish species to reduce feed cost. Meanwhile, the effect of dietary choline and betaine supplementation on fish performance was assessed. The aim of the present study was to investigate the effect of mixed protein schedules, combined with choline and betaine, on Nile tilapia performance. This experiment was conducted in a (4 × 3) factorial arrangement of treatments. Four mixed protein schedules were examined, in the presence of choline 0.3% and/or betaine 0.5%. The four mixed protein schedules were achieved by alternating diet (A; 31%CP) and diet (B; 24%CP) as follows: (6 days‐A), (5 days‐A/1 day‐B), (4 days‐A/2 days‐B) and (3 days‐A/3 days‐B). The results indicated that in the presence of betaine 0.5% and choline 0.3%, the optimal mixed protein schedule for tilapia was (3A/3B). Fish fed on the 4A/2B or 3A/3B schedules utilized protein more efficiently than fish fed on the (6A) schedule. Fish fed diets supplemented with betaine (b) only showed the highest energy retention. The lowest feed cost was recorded for fish fed on (3A/3B) in the presence of betaine 0.5% and choline 0.3% in fish diet.

“…Além disso, a colina é requerida para a síntese de lipoproteínas, responsável pelo transporte de gordura do fígado para outros tecidos, o que impede o acúmulo de lipídios nesse órgão. Em trabalhos realizados por Roem et al (1990), Shiau & Lo (2000), Kasper et al (2000Kasper et al ( , 2002, Vieira et al (2001) e El-Husseiny et al (2008 foi demonstrada a importância da metionina ou da colina no desempenho e concentração de lipídio hepático em tilápias; porém, as interações entre a metionina e a colina sobre a morfologia hepática não foram avaliadas. A deposição de lipídio no fígado de peixes cultivados é frequentemente intensa e indica desbalanço nutricional das dietas artificiais (Takashima & Hibiya, 1995).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos da metionina e colina sobre o desempenho produtivo e a morfologia do fígado de tilápia-do-nilo. Durante 87 dias, 160 peixes da linhagem Supreme, com peso vivo médio inicial de 77±0,8 g, distribuídos igualmente em 16 tanques de 1.000 L cada, foram cultivados em sistema com recirculação de água. Os peixes foram alimentados com rações, peletizadas, três vezes ao dia, até saciedade aparente. Foram utilizadas quatro rações com 33% de proteína bruta e 3.000 kcal kg -1 de energia digestível: controle, sem suplementação; suplementação com 3.000 mg kg -1 de metionina; com 2.000 mg kg -1 de colina; com 3.000 mg kg -1 de metionina e 2.000 mg kg -1 de colina. Não foi observado efeito do fornecimento de metionina ou colina sobre o ganho de peso diário, conversão alimentar, rendimento de filé, índice hepatossomático e gordura visceral. Os peixes alimentados com dietas suplementadas com colina e metionina tiveram menor teor de gordura nos filés e redução de inclusões lipídicas no tecido hepático. A suplementação com colina e metionina não afeta o desempenho produtivo de juvenis de tilápia-do-Nilo, mas a colina tem ação na utilização do lipídio hepático, evidenciada pela redução de inclusões lipídicas.Termos para indexação: Oreochromis niloticus, aminoácido, fígado, músculo, peixe, vitamina. Performance and hepatic morphology of Nile tilapia juveniles fed methionine and choline supplemented dietsAbstract -The objective of this work was to evaluate the effects of methionine and choline on the productive performance and on the liver morphology of Nile tilapias. During 87 days, 160 Supreme strain fish, with average weight of 77±0.8 g, equally distributed in 16 tanks with 1,000 L each, were cultivated in a recirculating water system. The fish fed on pelleted diets three times a day until apparent satiation. Four diets with 33% crude protein and 3,000 kcal kg -1 digestible energy were used: control, without supplementation; supplemented with 3,000 mg kg -1 methionine; with 2,000 mg kg -1 choline; with 3,000 mg kg -1 methionine and 2,000 mg kg -1 choline. No effects of methionine or choline supplements were observed on daily weight gain, feed conversion, fillet yield, hepatosomatic index and visceral fat. Fish fed on diets supplemented with choline and methionine had lower fat content in the fillets and reduction of lipidic inclusion in the hepatic tissue. Choline and methionine supplementation does not affect productive performance of Nile tilapia juvenile; however, choline has an important action for hepatic lipid utilization, as evidenced by the reduction of lipidic inclusions.
