Bile Acids for laying hens

Application of bile acids on breeders

At present, in theproduction of breeders, the quality of breeding management is generally judged through production indicators such as the qualified rate of breeder eggs, the hatcheryrate, the rate of mortality, and the potential for laying eggs. With the continuous improvement of breeds and breeding methods, these production indicators seem to have reached their peak. However, due to the restrictions of breeding management conditions, it is difficult to maximize the performance of indicators such as breeder mortality and egg production potential.

The phenomenon of "two highs" (high egg production rate and high death rate) and "one low" (significantly low number of eggs for hens to be housed) is common in breeder farms, which is caused fromour neglecting the mortality ratebut emphasizing on production rate, therefore, the breeder farm should specifically control the mortalityrate at the beginning of laying and the cumulative mortalityrate during the entire laying period. To solve this problem, we must first control the occurrence of chicken trauma at the beginning of production, and then extend the laying cycle of breeders to prevent early molting and reduce the late elimination rate of breeders. In the end, tracing back to the source, the health of the breeder itself is the focus that we need to pay attention to throughout the breeding process, which directly determines the production performance and benefits of the farm.

Breeders may face stress, excess energy, nutritional deficiencies, viral diseases, hepatobiliary diseases, heavy metals, aflatoxins and other factors during breeding, which seriously endanger theirhealth. As the largest detoxificationorgan, while functioning, the liver is also damaged to someextent, which in turn affects the production of breeders. Bile acid secreted by the liver not only has functions of emulsifyingfat, promotingthe digestion and absorption of fats, but also stimulates the liver to produce a large amount of thin bile, which excretes toxins and heavy metals, and relieves the burden on the liver. However, from the current nutritional level of breeders, bile acids secreted by the chickens cannot fully meet the needs of the chicken body, which requires addition of bile acids. In this regard, we have conducted relevant tests on the production of broilers and liver health with the addition of bile acids. The test results are shown in the following table:



From the data in Tables 1 and 2, it can be known that both parallel experiments have shown that after adding bile acids, the number of daily deaths is significantly reduced, and the number of deaths is reduced; the egg production rate is maintained smoothly; the double yolkrate and shell breaking rate have a downward trendbut the egg weight hasan increasing trend.

Broiler breeders have a high mortality rate, which ismainlycaused by liver problems. Liversyndrome caused by toxin accumulation is the main cause, mainly reflectingas liver rupture and hepatomegaly. The general solution is not significantly improved, butthe mortalityrate is not significantly reduced. The addition of bile acidscan promote the digestion and absorption of fat, maintain normal bile acid liver-intestinal circulation, reduce fatty liver caused by excessiveenergy and nutrition; stimulate the liver to produce a large amount of thin bile, expel toxins out of the body, and reduce the damage caused by toxins to the liver, andfinally, improve liver health, maintain chicken body health, and reduce the mortality rate of breeders. Bile acidscan promote the absorption of fat-soluble vitamins (VD3), and can improve the quality of egg shells to a certain extent. Bile acidscan increase the activity of endogenous emulsifiers and lipases, release the potential energy of the feed, and improve the production performance in the late laying period. Bile acid can increase the activity of thyroid hormones, which can effectively prevent the excessive deposition of abdominal fat in the late growth period of hens, thereby prolonging the laying cycle and improving the laying performance.

In short, long-term intake of bile acids in breeders can effectively improve liver health, increase egg production, reduce mortality, and increase economic returns.
