Pig feed additive for later period of fattening

Abstract

The invention belongs to the field of feed, and particularly relates to a pig feed additive for later period of fattening. The pig feed additive comprises complex enzyme preparations, compound probiotic preparations, gulfweed powder, chitosan, acidulant, plant extract and green feed. The pig feed additive has the advantages that the multiple probiotic preparations, the multiple complex enzyme preparations, the green feed and the plant extract are added in the formula of the feed, so that multiple substances beneficial to growth and development of pigs are provided to pig feed for the later period of fattening, ecological balance in intestinal tracts of the pigs in the later period of fattening can be maintained, absorption of microelements can be improved, growth and development of intestinal immune organs can be promoted, animal antibody level and macrophage activity can be improved, humoral immunity and cellular immunity of bodies can be enhanced, invasive pathogenic bacteria can be killed timely, immunity of animals to various diseases can be improved, and morbidity and mortality can be lowered greatly.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a special feed additive for fattening late pigs. 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 of fast fattening, provide timely high-quality compound feed to meet the growth 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.
