In recent years, the market has changed rapidly, and prices have risen madly, which has caused a great impact on the chicken industry. Feed cost is the largest expenditure in chicken production, accounting for about 70% of the cost. To pursue high economic benefits, we must ensure low input and high output, and master the appropriate input-output ratio. This requires the aquaculture production manager to always make the best and most suitable feed formula according to the changes in the market raw material price, in order to continuously improve the production efficiency.
It is well known that due to the influence of gossypol and palatability in cotton aphid, the amount of cotton aphid added to the feed of pigs is subject to certain restrictions. For egg breeders, the traditional addition of cotton aphid generally does not exceed 4%, but in recent years, the relevant data have reported that the amount of cotton aphid can not exceed 10%, whether such a large amount will be given to the egg breeder Does the production performance have an adverse effect?
In this regard, we have made a comparative test. The results show that it is feasible to increase the maximum amount of cotton aphid in the compound feed in the later stage of egg production. The production performance is not affected, and the comprehensive economic benefits. It is also considerable. We added 5% (control group) and 8% (experimental group) of cotton aphid in the late stage of egg breeder (400 days to 440 days old), and analyzed the performance under the same environment based on experimental data. Impact. The results were compared by experimental data: the death rate was 0.5% lower than that of the control group. The experimental rate of egg yield was 2.1% lower than that of the control group, and the egg production rate was basically unaffected. The experimental group was 0.1% higher than the control group. The fertilization rate of the experimental group was 0.79% higher than that of the control group, the dead embryo rate experimental group was 0.04% higher than the control group, and the hatching rate experimental group was 0.03% higher than the control group.
Comparison of economic benefits: the cost of laying eggs for each healthy mother: the experimental group is 0.03 yuan lower than the control group, that is, the 8% cotton mites added to the feed are priced less than the 5% cotton mites. . Although the experimental group provided 0.44 fewer eggs than the control group, the death rate was 0.5%, the fertilization rate was 0.79%, the dead embryo rate was 0.04%, and the hatching rate was 0.03%. Economically, the cost of laying eggs for each healthy mother is 0.03 yuan. Comprehensive analysis, the experiment of adding 8% cotton aphid in the middle and late feed of the egg breeder was successful, and the cost of laying eggs per healthy mother was 0.03 yuan lower than that of adding 5% cotton aphid.
