Additive to relieve weanling stress of piglets and feeding method thereof

Abstract

The invention discloses an additive to relieve weanling stress of piglets and a feeding method thereof. The additive comprises the following components by weight: 20-40 parts of glucose, 5-10 parts of sodium chloride, 3-10 parts of glycine, 0.1-0.5 part of potassium citrate, 0.1-1 part of monopotassium phosphate, 2-10 parts of potassium sorbate, 5-15 parts of lactic acid, 0.5-5 parts of citric acid and 2-10 parts of tea polyphenols. The feeding method of the additive is by preparing the additive into an additive solution, then preparing the additive solution and a creep feed into liquid creep feed for feeding weaned piglets . The additive can effectively improve the palatability of liquid creep feed, improve feed intake and daily weight gain of weaning piglets, and alleviate weaning induced growth retardation; at the same time, the additive prolongs preservation time of liquid creep feed, and reduces the workload of workers, so that the application of liquid creep feed in production become a reality.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to an additive and a feeding method for relieving weaning stress of piglets. Background technique [0002] Piglets are prone to weaning stress after weaning. The main reasons are: psychological stress and changes in the environment (mixing groups and leaving sows); changes in nutrient intake, from liquid breast milk to solid feed; changes in the way nutrients are digested, small Molecules to large-grained plant starch and protein; beneficial intestinal bacteria decrease, harmful bacteria increase; loss of maternal antibody protection, immune function decline, etc. The weaning stress of piglets leads to a sudden decrease in feed intake of weaned piglets, insufficient energy intake of piglets, atrophy of intestinal villi of weaned piglets, growth stagnation or even negative growth of piglets, often accompanied by diseases such as diarrhea, and an increase in the proportion of d...

Problems solved by technology

However, since the nutrient level of the creep feed is very high, and the temperature of the nursery needs to be around 30 degrees, under high temperature and high humidity conditions, the nutrients in the creep feed are easily oxidized, deteriorated and corrupted. The deteriorated feed will inevitably affect the health of weaned piglets, causing Diarrhea and other diseases lead to growth retardation; it is reported that when the ambient temperature is greater than 30 degrees, the porridge-like feed will be obviously oxidized and deteriorated (fat oxidative rancidity and protein corruption) after being stored for more than 3 hours, which requires feeding every 3 hours. Replacing the feed and cleaning the trough within hours greatly increases the labor intensity of the workers, making it impossible for most pig farms to achieve
