How to formulate ecological feed? Key technical points explained in detail
1. Wean in time and group reasonably
After lambs reach 2 to 3 months of age, separate the mother from the lambs for weaning. This allows the ewes' condition to recover quickly, achieving the goals of early estrus, early mating, and high yield with multiple births, while also promptly training the lambs' ability to live independently; @#@229@#@ for lambs after weaning, group them reasonably by sex, size, and strength in separate pens to prevent the strong from becoming stronger and the weak from becoming weaker, which would affect the overall development level and uniformity.
2. Mate at the right time to improve the reproduction rate
Mating too early will affect the ewe's own growth and development, thereby reducing the ewe's reproductive performance. Mating time: if estrus occurs in the afternoon, mate the next morning, with an interval of 8 to 12 hours, then mate once more. At the same time, keep good mating records to prevent mismating or unclear delivery dates that cause unnecessary economic losses.
3. Use resources and formulate feed reasonably
Correctly use silage, ammoniation, alkalization, and other techniques to treat crop straw, and strictly prohibit feeding forage that has become moldy and deteriorated due to improper silaging, as well as ammoniated or alkalized forage that has not been rinsed clean; strictly prevent coarse feed from being ground too fine. Production practice has proven that long-term feeding of overly fine coarse feed can easily cause rumination disorders in sheep, as well as diseases such as rumen atony, feed impaction, and bloating. The length of coarse feed for sheep farming should be 1 cm to 3 cm, so that sheep can ruminate normally after eating. The formulation of concentrate feed should be based on local feed resources and reasonably adjusted according to different sheep breeds and different growth stages. After formulation, the energy, protein, minerals, and vitamins in the feed must meet the needs of sheep at different stages of growth, reproduction, and lactation. The ammonia-to-sulfur ratio in the feed should reach 7:1 to 8:1, and the calcium-to-phosphorus ratio should reach 1:1 to 2:1. When feeding non-protein nitrogen feed, sulfur and ammonia must be supplemented.
1 The proposal of ecological feed
The pollution caused by livestock production to the environment mainly comes from livestock and poultry manure and urine excreta and the residue of toxic and harmful substances in food, and its root lies in feed. In order to maximize the production performance of livestock and poultry, livestock and poultry raisers and feed producers often intentionally increase the dietary protein concentration in feed formulation, causing increased nitrogen excretion in manure and urine; they do not pay attention to the accumulation of mineral elements, trace elements, and toxic and harmful substances in livestock and poultry bodies or the excretion of incompletely digested substances, resulting in excessive harmful substance residues in livestock and poultry food. Sheep farming endangers human health. After phosphorus, copper, arsenic, zinc, and pharmaceutical additives are excreted, they cause water and soil pollution and worsen people's living environment.
With the further deepening of animal nutrition research and the continuous enhancement of human environmental awareness, solving the public hazards of livestock and poultry products and reducing livestock and poultry pollution to the environment have been put on an important agenda. Ecological feed is the use of ecological nutrition theories and methods to address issues such as public hazards of livestock and poultry products and reducing livestock and poultry pollution to the environment, carrying out strict quality control throughout the processes of raw material selection, formula design, processing, and feeding, and implementing animal nutrition regulation, thereby controlling possible public hazards of livestock and poultry products and environmental pollution, so that feed achieves the effects of low cost, high benefit, and low pollution.
