Embodiment 1

[0037] Get 300 breeds that are outside Sanyuan "Du Changda", healthy growing pigs with a body weight of 80 ± 2.3kg, and randomly divide them into 5 treatment groups, wherein, the first group is the control group, and each treatment group has 6 repetitions. Each replicated 10 pigs, and the pigs were fed at a temperature range of 30°C to 35°C. The experimental diet was formulated according to the nutritional requirements of pigs in the United States NRC (2012).

[0038] The premixed feed is provided with different combinations of astragalus superfine powder, L-carnitine, vitamin C, vitamin E, tea polyphenols, methionine chromium, yeast selenium, sodium selenite, zinc sulfate monohydrate, zinc protein, copper sulfate pentahydrate and protein copper were added to the diets of the five treatment groups, and the test period was 40 days. During the test period, the feeding management procedures and immunization procedures were carried out according to the conventional commercial pig ...

Abstract

The invention relates to a premixed feed capable of relieving heat stress of growing and fattening pigs. The premixed feed comprises the following components in percentage by weight: 4-6 percent of 98% L-lysine hydrochloride, 5-8 percent of sodium bicarbonate, 2-4 percent of 50% choline chloride, 5-20 percent of ultrafine astragalus powder, 2-4 percent of an acidifying agent, 1-1.2 percent of composite vitamins, 2-3 percent of a trace element additive and 64-78 percent of a carrier. Compared with the prior art, the premixed feed disclosed by the invention has the advantages that the palatability of the feed can be obviously improved, the daily intake of the pigs is increased, the physiological status of bodies under a condition of heat stress is effectively changed, harmful bacteria are reduced, the possibility of constipation, fever and poisoning of the pigs is effectively reduced, and a healthy digestive tract is formed; furthermore, the acid-base balance of liquid environments inside and outside cells can be adjusted, and thus healthy and quick growth of the growing and fattening pigs is facilitated.

Description

technical field [0001] The invention relates to a premixed feed, in particular to a premixed feed for alleviating heat stress of fattening pigs. Background technique [0002] In modern animal husbandry production, especially in the hot summer season, high temperature and high humidity is a common and influential stressor - heat stress. Heat stress refers to the sum of non-specific physiological responses made by the thermal environment to any requirements put forward by the body when the body is in a high-temperature environment. Heat stress changes various physiological and biochemical reactions of animals, reduces growth performance, product quality, reproductive performance and immune performance, and brings serious economic losses to the breeding industry. With the general increase of global temperature, the degree of production intensification and the continuous improvement of animal welfare requirements, the problem of heat stress has attracted people's attention. ...
