Effects of Protective Compound Acidifier on Growth Performance of Weaned
At present, in our country generally the implementation of piglets 3 to 4 weeks of age weaning, which can easily lead to piglets "early weaning syndrome", manifested as loss of appetite, digestive disorders, diarrhea, growth retardation and low rate of nutritional conversion. On the one hand, due to weaning piglet digestive system development is not perfect, lack of gastric acid secretion, on the other hand feed dairy products can not meet the nutritional needs of piglets, resulting in reduced lactic acid, resulting in piglets gastrointestinal pH significantly increased, and further Digestive enzyme activity is reduced, proteaseogen activation is limited, so the fish meal, soybean meal and other protein feed can not be well digested. Feed digestion is not complete, for the small intestine bacterial proliferation and provides a substrate, which appeared intestinal dysfunction, piglets dehydration diarrhea, loss of appetite and growth retardation and other early symptoms of weaning syndrome.
However, the growth rate of piglets from weaning to 10 to 11 weeks of age determines the performance of the late harvest and the best carcass quality. Therefore, to strengthen piglets nutrition, raising piglets growth rate by the farmers attention. Weaning piglets dietary additives in the acid, can supplement the lack of gastric acid secretion, improve the activity of digestive enzymes, lactic acid bacteria and other probiotics to promote the reproduction of harmful microbial proliferation, to overcome or alleviate the weaning syndrome. The effects of adding acidifier on the growth, gastrointestinal acidity and digestive enzyme activity of piglets were studied by adding 0.1% and 0.3% compound acidifier as control.
1 Materials and methods
1.1 Experimental animals and design
A total of 6 treatments of 72 weeds of 28 days of age (6 ± 1.03) kg were randomly divided into three groups according to the principle of similarity and similarity, and each treatment 2 Repeat, each repeated 12 pigs, male (castrated boar) mother half mixed feed. Feeding period 28d.
1.2 acidifier
The protective compound acidizing agent is produced by Guangdong Lvyuan Feed Technology Co., Ltd. and Biogenic Biotechnology (Shenzhen) Co., Ltd., whose main components are protected phosphoric acid, lactic acid, citric acid, fumaric acid, excipient silica, It is characterized by adding to the feed and will not react with the nutrients of the feed, do not produce gas and water.
1.3 Basic diets and nutritional levels
Basal diet and nutrient levels are shown in Table 1. The control group and the control group were the same diet, the control group without acidifier, test group A to add 0.1% acidifier, test group B to add 0.3% acidifier.
