Preparation Technology of Ecological Feed

1. Timely weaning and reasonable grouping

After 2 months to 3 months of age, the mother and son should be weaned separately, which can quickly restore the physique of the ewe, achieve the goal of early estrus and early mating, prolific and high yield, and exercise the independent living ability of the lamb in time. @ 229 lambs are reared in groups and circles reasonably according to male and female, size and strength, so as to prevent the strong from getting stronger and the weak from getting weaker, affecting the overall level of development and evenness.

2. timely breeding to improve the reproduction rate.

Early mating will affect the growth and development of ewes, thus reducing the reproductive performance of ewes. The time of mating: estrus in the afternoon, mating in the next morning, with an interval of 8 hours to 12 hours, and mating again. At the same time, mating records should be made to prevent unnecessary economic losses caused by mismatch or unclear delivery date.

3. Make use of resources and prepare feed reasonably.

Correct use of silage, ammoniation, alkalization and other technologies to deal with crop straw, it is strictly forbidden to feed moldy and deteriorated forage grass due to improper silage and to wash unclean ammoniated and alkalized forage grass; strictly prevent coarse fodder powder from being too fine. Production practice has proved that long-term feeding of over-fine roughage is easy to cause ruminating disorders, forestomach relaxation, accumulated food, gas and other diseases in sheep. The length of roughage for raising sheep is 1 cm ~ 3 cm, and the sheep can regurgitate normally after feeding. The preparation of concentrate feed should be based on local feed resources, different breeds of sheep and different growth stages. After preparation, the energy, protein, minerals and vitamins in the feed should meet the needs of sheep in different stages of growth, reproduction and lactation. The ratio of ammonia to sulfur in the feed should reach 7 ∶ 1 to 8 ∶ 1, and the ratio of calcium to phosphorus should reach 1 ∶ 1 to 2 ∶ 1. When feeding non-protein nitrogen feed, thiamine must be supplemented.

1 proposal of ecological feed

The environmental pollution caused by animal husbandry production mainly comes from the excretion of livestock and poultry manure and the residue of harmful substances in food, which is rooted in feed. In order to maximize the production performance of livestock and poultry, livestock and poultry breeders and feed producers often deliberately increase the dietary protein concentration in feed preparation, resulting in an increase in the excretion of nitrogen in feces and urine. Do not pay attention to the enrichment of mineral elements, trace elements and toxic and harmful substances in feed and the discharge of imperfect substances in livestock and poultry, resulting in excessive residues of harmful substances in livestock and poultry food, and raising sheep is harmful to human health. after the discharge of phosphorus, copper, arsenic, zinc and drug additives, it causes soil and water pollution and deteriorates people's living environment.

With the further deepening of animal nutrition research and the continuous enhancement of human awareness of environmental protection, solving the public nuisance of livestock and poultry products and reducing the environmental pollution of livestock and poultry have been put on the agenda. Ecological feed is to use the theories and methods of ecological nutrition to carry out strict quality control from the process of raw material selection, formula design, processing and feeding, focusing on the public pollution of livestock and poultry products and reducing the environmental pollution of livestock and poultry products. and implement animal nutrition regulation and control, so as to control the possible pollution of livestock and poultry products and environmental pollution, so that the feed can achieve the effect of low cost, high benefit and low pollution.
