Embodiment Construction
[0027] The technical scheme of the present invention will be specifically described below in conjunction with embodiment:
[0028] 1. Preparation of biological preparations for improving the quality of laying chickens
[0029] Eliminate the preparation of laying chicken quality improver and carry out by the component formula that table 1 adopts (unit in table 1 is parts by weight):
[0030] Table 1: Formula composition of quality improver for chicken hens eliminated
[0031]
[0032] The preparation method: mix the above-mentioned components uniformly so that the coefficient of variation of uniformity (CV) is less than 5%, so as to obtain the meat quality improver. At the same time, it is used in animal experiments to verify its application effect.
[0033] 2. Animal experiments:
[0034] 1. Experimental animals and grouping
[0035] (1) Animals: 3,600 Jinghong No. 1 laying hens were eliminated at the age of 400 days, and were provided by Dachang Chicken Cooperative.

The invention belongs to the field of feed additives, and relates to a biological agent for improving meat quality of obsolete laying hens as well as a preparation method and application of the biological agent. The meat quality improvement biological agent comprises lactobacillus acidophilus, lactobacillus bulgaricus, bifidobacterium infantile, vitamin E and palm oil, and the preparation method comprises the following steps of uniformly mixing the components, adding 0.1-0.3% of the improved biological agent into the livestock and poultry feed according to the total weight of the feed. The improved biological agent disclosed by the invention can be used as a substitute of antibiotics, eliminates drug residues, improves the quality of chicken and egg products, remarkably improves the content of inosinic acid and intermuscular fat in the muscles of laying hens, and makes the chicken smooth, tender and tasty; The biological agent can also be used for preventing and treating laying hen diarrhea, improving immunity and disease resistance, reducing the death and culling rate of laying hens in the egg laying period, and improving the feed conversion rate and egg laying performance. The henhouse environment can be purified, and the ecological environment can be protected and improved.
Description
technical field [0001] The invention relates to a biological preparation for improving the quality of eliminated laying chickens, belonging to the field of feed additives. Background technique [0002] At present, the breeding quantity of commercial layer chickens at home and abroad tends to be stable, the production structure is gradually improved, the number of large-scale layer farms is gradually increasing, and the breeding technology and equipment level of large-scale layer farms are improved. The production efficiency of laying hens has been improved. However, in order to pursue the greatest economic benefits, most of them adopt high-density cages, which will cause the laying hens to be in a state of stress for a long time and be stimulated by many unfavorable factors. It was eliminated by chicken farms due to the early decline in egg production capacity. In fact, the eliminated layer chicken has the characteristics of high protein, low fat, and low cholesterol. The ...
