Pig feed for early stage of fattening and preparation method of pig feed

Abstract

The invention belongs to the field of feed, and particularly relates to pig feed for the early stage of fattening. The pig feed comprises corn flour, beer vinasse, wheat bran, soybean meal, peanut meal, peanut vine bran, sesame seed meal, rapeseed meal, palm meal, rice bran, sweet potatoes, potatoes, sweet potato vine bran, brown seaweed, complex enzyme preparations, compound probiotic preparations, citric acid, sodium carboxymethylcellulose, salt, fishbone meal, shell powder, calcium carbonate, lysine, methionine, ginger powder, premix, soybean dietary fiber flour, green feed and chitosan. The pig feed has the advantages that the green feed is added into the formula of the feed innovatively, digestion and absorption capabilities of pigs in the early stage of fattening are improved, growth speed of the pigs is increased, and disease resistance of the pigs in the early stage of fattening is improved; various kinds of feed not easy to digest and absorb is fermented into ingredients easy to digest and absorb, and growth of the pigs in the early stage of fattening is facilitated.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special feed for pigs in the early fattening period, and also relates to a preparation method of the pig feed in the early fattening period. Background technique [0002] 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 early stage of fattening. [0003] The goal of feeding and management of fattening pigs is to increase daily gain, shorten the fattening period, reduce the feed-to-weight ratio, and increase the lean meat rate, but the most important stage for commercial fattening pigs is the early stage of pigs. As the saying goes: Newborn weighs 1 tael, weaning weighs 1 catty, and the slaughter will be 10 catties more. This fully demonstrates the importance of the early growth of pigs in the entire pig production. [0004] Animals eat for energy. Generally speaking, the more energy a pig consumes dai...

[0009] 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

[0010] 3. Crude fiber content 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.

[0011] 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.
