Technical Field

The invention belongs to the technical field of animal feed additives, and particularly relates to a chicken feed additive compounded by taurine and glycocyamine.

Background

Taurine, chemical name 2-aminoethanesulfonic acid, is dissolved in water and 95% ethanol, and exists in cytoplasm liquid of animal tissue, and research shows that the taurine can be combined with bile to form bile components, thereby promoting fat emulsification; taurine is the main free amino acid in retina, and the lack of taurine in animals can cause visual function reduction; taurine also acts as a neurotransmitter or hormone, and has a wide range of nutritional and regulatory effects on the cardiovascular system. After the taurine is added into the daily ration of the chicks, the weight is increased, the feed conversion rate is improved, and the taurine serving as a feed additive has positive effects on the growth performance and the immune function of the chicks, but has little effect on adult laying hens.

Guanidinoacetic acid, chemical name nmiglycine, is generally white or yellowish crystalline powder or flake crystalline, and is a creatine direct precursor. Murakami et al added guanidinoacetic acid at various doses of 0.06% -0.24% to quail ration for meat breed, found that guanidinoacetic acid in quail eggs is linearly increased and can increase the content of guanidinoacetic acid in muscle of hatched quails, and subsequently showed that the addition of guanidinoacetic acid can increase the reproductive performance and the content of creatine in quail offspring muscle creatine.

Although the addition of taurine or guanidinoacetic acid to animal feed has many benefits on the growth of animals, the simultaneous addition of taurine and guanidinoacetic acid to chicken feed as a chicken feed additive is not known, nor is the effect on the growth and egg production of chickens.

The daily ration comprises 60% of corn, 9.5% of corn cob powder, 23% of soybean meal, 1% of calcium bicarbonate, 5% of shell powder, 0.5% of salt, 0.2% of vitamin and 0.8% of methionine. The additives with different formulas are added into the basic ration in different proportions, and the control group is only fed with the basic ration.

The proportion gradient of the addition amount of taurine in the basic ration is set to be 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4% and 1.6%; the proportion gradient of the additive amount of the glycocyamine in the basic ration is set to be 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4% and 1.6%; taking 10 laying hens as an experimental group, counting the total number of eggs laid within 10 days, and calculating the laying rate: the total egg laying amount is 100% per 100X.

The experimental results are shown in fig. 1-2, and the maximum laying rate is obtained when the addition amount of taurine and the addition amount of glycocyamine are both 1.0%.

Example 2
