Effect Of Betaine On Animal Performance
Dec 12, 2017

Earlier Hurtung (1953) reported that the addition of betaine dialysate concentrate to whole plant-based diets significantly increased the growth rate of single-crown white Lo Lo red broilers. Studies by Pesti (1979) showed that addition of 0.23% betaine hydrochloride to diet consisting mainly of corn and soybean meal (23% crude protein, 13.38 MJ / kg metabolic energy, 0.37% methionine, 0.74% The daily gain of 21-day-old broilers increased by 14.53% and the feed-to-weight ratio decreased by 5.56%. In 1992, James added 500,1000,1500 mg / kg betaine to the same basal diet (0.37% methionine, 0.69% sulfur methionine, 0.31% methionine, 0.64% sulfur amino acids) Methionine compared to the results showed that the growth rate of broiler chickens basically the same, and feed conversion efficiency of slightly better betaine. In Sweden, similar results were obtained with the addition of 1100 mg / kg betaine to the same amount of methionine on wheat and soybean meal-based diets. Studies by Eprotrn (1986) showed that adding betaine 622 mg / kg to diet containing methionine 0.35% increased total egg production by 2% for LSL hens aged 24-36 weeks and reduced egg-to-egg ratio by 2%.

Finnish sugar company research shows that: 0.5% to 1.5% of betaine products added to several kinds of fish and shrimp feed, found on the Atlantic salmon, rainbow trout, red tilapia, trout, eel and shrimp and other crustaceans Has a significant stimulating effect. As with the rainbow trout test, betaine increases initial body weight by 0.15 g of rainbow trout, increases weight gain and feed conversion efficiency by about 20% after 8 weeks, and improves juvenile adaptability and survival. Another example is the Atlantic salmon test, betaine can increase the gain of 31.9%, reduce the feed coefficient of 24.60%. According to the research by Yan Youli (1993), 0.3% betaine (98%), 0.5% and 0.3% crude betaine hydrochloride (67%) were added to second-grade carp feed with crude protein of 31.69% and crude fat of 3.89% And boutique (98%) respectively. The average tail weight increased by 49.32%, 41.78% and 43.84% respectively, and the feed conversion coefficient decreased by 24.16%, 22.13% and 14.13% respectively. Zhang Yangjun (1991) studies have shown that the use of betaine instead of the appropriate amount of choline chloride in feed, shortens the feeding time of Macrobrachium rosenbergii 1/4 ~ 1/2, increased feeding capacity, 150 days Macrobrachium average body length increased 27.63%, the average tail weight increased by 20.27% and the feed coefficient decreased by 8%. Carp trials conducted by the Bureau of Fisheries in Chaoyang District, Beijing showed that 0.3% betaine increased yield by 30% and addition of 0.10% betaine compound increased yield by 38%.
