“…At 9 weeks of age, in our study, the birds fed the organic diet supplemented with betaine had significantly lower body weights than birds on the other organic diets. It is feasible that the potentially beneficial effects of betaine were negated by the fishmeal in the diet, which would have provided choline (Kidd et al, 1997). However, the inability of betaine to compensate for suboptimal levels of methionine are consistent with the findings of McDevitt et al (2000).…”

The effects of organic diets, with or without supplements of betaine, saponin, fructo-oligosaccharide and methionine, on the health, performance and gut flora of pullets were investigated. A comparison was also made between birds fed organic diets and those fed a non-organic diet. Day-old Lohmann Tradition pullets were reared in 24 groups of 64 chicks indoors until 11 weeks, and then in 48 groups of 24 to 27 chicks with access to range until 17 weeks of age. Groups of birds were fed one of eight diets, a conventional rearing diet with supplementary amino acids, an organic basal diet, organic basal plus methionine and organic basal supplemented with one of the test ingredients. At most stages of growth the birds fed the conventional diet and those fed the basal diet with methionine performed better than those that had no supplemental methionine. Other dietary treatments had no consistently significant effect on growth, the microbial populations within the gastro-intestinal tract of the birds or the number of parasite eggs excreted. After 5 weeks with access to range, the birds that were fed three out of five diets regarded as deficient in sulphur amino acids achieved similar weights (P . 0.05) to birds that received diets adequate in sulphur amino acids. Health and welfare of birds fed organic diets was not adversely affected; however, an investigation of birds housed in larger flocks and taken into the laying phase, when physical demands on birds are greatest, is required.

“…While the limited physical movement might be associated with reduced energy expenditure, the pigs might also be exposed to a higher level of stress due to artificial confinement and feed restriction, compared to animals maintained either in group pens or in larger pens on ad libitum feeding. It has been previously suggested that betaine has positive effects on growth and metabolism in animals that are exposed to various physiological stresses (Virtanen 1995; Barak et al, 1997;Kidd et al, 1997;Junnila et al, 2000).…”

“…The use of betaine as an ingredient in livestock diets is not a new concept. It was initially introduced to the feed industry as a replacement for methionine and choline in poultry and fish diets, where it is presumed to act both as methyl donor and as an osmoprotectant (Kidd et al, 1997). In swine, it has been suggested that betaine reduces carcass fat deposition (Cadogan et al, 1993;FernandezFıgares et al, 2002).…”

Dietary betaine may reduce carcass fat in growing pigs. We explored the effects of betaine on short-term growth and in vivo and in vitro fatty acid oxidation. Pigs were housed in metabolism crates and fed diets containing either 0% (control), 0.125% or 0.5% betaine at 80% of ad libitum energy intake. Fatty acid oxidation was measured during intravenous infusions of 1-C-palmitate and in hepatocytes incubated in the presence or absence of betaine and carnitine. 13CO and palmitate isotopic enrichments were determined by mass spectrometry. Pigs consuming 0.125% and 0.5% 2 betaine for at least 9 days had growth rates that were 38% and 12% greater than controls, respectively. Feed efficiency was also improved with betaine. Fasting increased palmitate oxidation rates 7-8-fold (P-0.01), but betaine had no effect in either the fed or fasted state (P)0.1). For hepatocytes, carnitine but not betaine enhanced palmitate oxidation. This response suggests that previously observed reduction in adipose accretion must be via a mechanism other than oxidation. Betaine had no effect on plasma non-esterified fatty acids or urea nitrogen. Under the confinement conditions in this study, dietary betaine improved animal growth responses, but it had no apparent effect on either whole body or hepatic fatty acid oxidation. ᮊ

“…Outro doador de grupamento metilado é a colina, vitamina essencial na transmissão de impulsos nervosos para as membranas celulares (Kidd, 1997). A demanda constante de grupos metilados conciliado à baixa concentração celular, faz com que ocorra a oxidação mitocondrial da colina à betaína (Remus, 2000).…”

RESUMOO objetivo deste trabalho foi avaliar o efeito da inclusão de betaína em dietas sobre o desempenho e morfometria intestinal de frangos de corte, durante os períodos de 1 a 7 e 8 a 21 dias de idade. Foram utilizados 1.408 pintos de corte machos Cobb, distribuídos aleatoriamente em 4 tratamentos com 16 repetições de 22 aves, em quatro câmaras climáticas. Os tratamentos foram: i) controle positivo -dieta formulada de acordo com as exigências nutricionais da ave; ii) controle negativo -com redução nos níveis de metionina e colina; iii) controle negativo + suplementação de 0,092% de betaína em substituição parcial de metionina e total da colina iv) controle negativo + suplementação de 0,1% de betaína natural em substituição parcial de metionina e total da colina. O consumo de ração, o ganho de peso e a conversão alimentar foram avaliados aos sete e 21 dias de idade. Aos 25 dias avaliaram-se as variáveis altura e profundidade de cripta jejunal, em que os resultados obtidos foram submetidos à análise de variância e teste de comparação de médias; já os resultados obtidos com a suplementação da betaína nas rações demonstraram efeitos positivos apenas no consumo de ração na fase de 1 a 7 dias e altura dos vilos da mucosa do jejuno na fase de 8 a 21 dias. A suplementação de 0,1% betafin (96% de betaína natural) na ração proporcionou melhorias nas características morfológicas do intestino delgado de frangos de corte.

Were used 1,408 Cobb male broiler, randomly assigned into 4 treatments with 16 replicates of 22 birds in environmental chambers. The treatments were: i) positive control -diet formulated according to the nutritional requirements of the birds; ii) negative control -with reduction levels of methionine and choline; iii) negative control + 0.092% supplementation of betaine in substitution of methionine and total choline; iv) negative control + 0.1% supplementation of natural betaine to replace partial methionine and total choline. Were evaluated feed intake, weight gain and feed conversion at 7 and 21 days old. At 25 days were evaluated crypt height and depth of jejunum. The results were analyzed by ANOVA and mean comparison test. The results obtained with the supplementation of betaine in the feed only demonstrated a positive effect on feed consumption during 1 to 7 days, and villous height of the jejunum in the period of 8 to 21 days. Supplementation of 0.1% betafin (96% natural betaine) in the diet provided significant improvements in the morphological characteristics of the small intestine of broilers.
