Pig feed for latter fattening period and preparation method thereof

Abstract

The invention belongs to the field of feed and in particular relates to a pig feed for the latter fattening period. The pig feed disclosed by the invention comprises corn flour, distillers' grains of Baijiu, wheat bran, soybean meal, peanut meal, peanut vine meal, sesame seed meal, rapeseed dregs, palm meal, rice bran, sweet potatoes, potatoes, sweet potato vine meal, brown seaweed, a complex enzyme preparation, a complex-probiotic agent, citric acid, sodium carboxymethyl cellulose, edible salt, fishbone dust, shell powder, calcium carbonate, lysine, methionine, ginger powder, premix, soybean dietary fiber flour, green feed and chitosan. The feed formula disclosed by the invention has the innovation that the green feed is added, so that the absorption and digestion ability of pigs in the latter fattening period is improved, the growth speed of the pigs is improved, and the disease resistance of the pigs in the latter fattening period is improved. In addition, a variety of feeds which are difficult to digest and absorb are fermented and transformed into components which are easy to digest and absorb, and the growth of the pigs in the latter fattening period is facilitated.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a special feed for fattening late pigs, and also relates to a preparation method of the above-mentioned late fattening pig feed. Background technique [0002] The fattening pigs are divided into the early stage of fattening, 25-60 kg is the early stage of fattening, and 60-100 kg is the late stage of fattening. [0003] After the weight of the pig reaches 60 kg in the late fattening period, the physiological function is gradually improved, the digestive system has been greatly developed, the ability to digest various substances and the absorption of various nutrients in the feed have been greatly improved, the nervous system and The body's resistance to various external stimuli is also greatly enhanced and more comprehensively developed, and it also has greater adaptability to the surrounding environment. During this period, the growth rate is the fastest. We should seize the opportunity o...

Problems solved by technology

2. Unbalanced protein and amino acid levels In order to reduce production costs and improve economic benefits, the protein level of growing and finishing pigs is generally low in the later stage. If the protein level of the feed is reduced and the amino acid level is not balanced, it will greatly affect the later stage. weight gain

3. The content of crude fiber is unreasonable. The content of crude fiber has a great relationship with the feed intake of pigs. At present, the most troublesome thing in pig production is the low feed intake of growing and finishing pigs in the later stage

In the early growth process of fattening pigs, in order to prevent diseases, producers add long-term large doses of antibiotics to the feed. Although this can improve the animal’s disease resistance, it will also cause some bacteria to develop drug resistance. Once these bacteria cause disease , It is quite difficult to treat, and often causes endogenous infection and superinfection, which reduces the body's immunity and disease resistance, and hinders the normal growth and development of the body in the later stage.
