Application of cholic acids in animal husbandry
A. Effects of cholic acids on the performance of piglets
In order to ensure enough energy in piglets fed diet, need to add in the feed formulation in fat, however, Zi liver function is not perfect, bile acid secretion, digestion and absorption of fat is very limited and undigested fat easily cause diarrhea, in the feed to add bile acids can solve the problem of piglets in fat digestion. The Ohio State University Reinhart, (1989) in weanling pig diets adding 0.3% bile acid significantly increased body weight gain and feed intake, fat intake and fat table absorption amount increased, nitrogen intake and nitrogen storage allowance also significantly increased (P < 0.01).
B. effects of cholic acids on the production performance of poultry
Bile acid can effectively improve the performance of poultry.Gomez (1979), reported that feed add bile acid, the white Plymouth Rock chicken fat apparent digestibility increased 2.l%. bile acid can improve broiler on fat utilization (Pullen, l983).
Fatty liver of laying hens are laying hens common a nutritional and metabolic diseases, affect liver function and serious caused by rupture of liver cells, liver hemorrhage and death. Suffering from fatty liver of chickens is difficult to appear laying peak, to the aquaculture industry brings great economic losses, in feed to add extra bile acid can prevent fatty liver caused a series of problems, conducive to healthy hens, prolong the duration of egg laying peak.
C. effects of cholic acids on the growth of aquatic animals
Feed add bile acid can improve the nutritional value of snapper feeds. The weight gain rate of 45.73% ~ 68.6% higher than the control group, improve feed utilization 10.86% ~ 21.88% (disciple pill repair, 1981). Systems such as (2003) in the feed to add 100 mg / kg of Likang (bile acids), Allogynogenetic silver crucian carp growth rate increased by 5.1%, feed conversion rate was increased by 22.9%, reduce the proportion of visceral, fish feed ratio has been increased. Ishihara Xiura (1987), also found that feed add bile acid, improve Pagrosomus major color, improve the commodity value of the fish farming.
D. the effect of cholic acids on the appearance and quality of animal fur
Bile acids can increase the absorption of fat and fat soluble vitamins in animals, thereby improving the quality of animal fur.
In short, bile acid as a feed additive, can effectively alleviate the fat and fat soluble vitamins due to indigestion caused by a variety of problems, improve the conversion rate of fat, reduce the cost of feed.
