Problems solved by technology

However, weaned piglets lack the energy and glutamine required for nucleotide synthesis, which results in a shortage of endogenous nucleotides and requires supplementation of exogenous nucleotides
[0007] At present, there are many reports on the single application of prebiotics, probiotics and nucleotides, but few reports on the combined application of these three

Embodiment 5

[0035] Test animals and groups:

[0036] A total of 300 weaned piglets with similar body weight and about 30 days old were selected and randomly divided into 5 groups according to their initial body weight, which were control group and experimental group 1-5. There were 6 replicates in each group, and 10 pigs in each replicate. Each treatment was fed with the corresponding diet, and the whole experiment was free to eat and drink. The feeding and management methods were determined according to the specific conditions of the test site.

[0037] Control group: the basal diet was determined according to the conditions of the test site, without any change, and its formula and nutritional components are shown in Table 2;

[0038] Test group 1: Add 0.1wt% of the feed additive in Example 1 to the basic diet formula;

[0039] Test group 2: Add 0.1wt% of the feed additive in Example 2 to the basic diet formula;

Abstract

The invention discloses application of a feed additive in promoting intestinal development of weaned piglets. The additive is prepared from the following components in parts by weight: 1-6 parts of prebiotics, 1-6 parts of probiotics and 1-5 parts of nucleotide. According to the feed additive disclosed by the invention, reasonable proportioning of the prebiotics, the probiotics and the nucleotideis realized, the intestinal development of weaned piglets is effectively improved, the immunity is enhanced, and the influence of weaning stress of the piglets on intestinal metabolism is reduced; diarrhea of weaned piglets is reduced, the survival rate is increased, and antibiotics are replaced; the feed conversion rate is improved, and the economic value is improved. The application is of greatsignificance to modern scientific, intensive and large-scale pig raising production.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to the application of a feed additive in promoting intestinal development of weaned piglets. Background technique [0002] The research and application of feed formula for early weaned piglets is directly related to the growth and performance of weaned piglets in the future. In my country, compared with the traditional weaning age of piglets, weaning at the age of 21 to 35 days is generally called early weaning, and weaning before 21 days is called super early weaning. However, early weaned piglets, especially ultra-early weaned piglets, face problems such as immature digestive tract, poor gastrointestinal function, immune insufficiency, and low disease resistance, and weaning is also related to the physiological, psychological, environmental and nutritional status of piglets. These will cause piglet allergies, decreased feed intake, low feed utilization, and delayed growth and develo...
