Nutrient supplement for first-delivery sows as well as preparation method and use method of nutrient supplement

Abstract

The invention provides a nutrient supplement for first-delivery sows, and belongs to the technical field of breeding of first-delivery sows. The nutrient supplement comprises 100-200 parts of poly-isomaltose, 100-200 parts of baking soda, 50-100 parts of probiotics, 60-150 parts of chitosan oligosaccharides, 100-150 parts of L-Lysine monohydrochloride, 50-100 parts of methionine, 50-120 parts of calcium lactate, 0.1-0.3 part of zinc glycinate, 0.08 -0.12 part of manganese glycinate, 0.01-0.03 part of cupric glycinate, 50-100 parts of an acidulant, 150-200 parts of vitamin E, 10-15 parts of vitamin A, 2-3 parts of vitamin D3 and 10-500 parts of silicon dioxide. A preparation method of the nutrient supplement comprises the following steps of weighing the components in parts by weight, sequentially adding the components in parts by weight to a mixing machine in the sequence from the big components to the small components, performing uniform mixing, and performing subpacking with a non-toxic bag. According to the nutrient supplement, the physical development of the first-delivery sows can be promoted, the firstborn stress of the first-delivery sows can be reduced, the body storage of the first-delivery sows can be strengthened, the food consumption of the sows at the early period of a lactation period can be increased, the disease resistance of the first-delivery sows at a perinatal period can be strengthened, the syndromes of the sows for second pregnancy can be alleviated, the service life of the sows can be prolonged, and the rejection rate of the sows can be reduced.

Description

technical field [0001] The invention belongs to the technical field of first-parity sow feeding, and specifically relates to a nutrition enhancer for first-parity sows and a preparation and use method thereof. Background technique [0002] At present, my country's pig industry is transforming into large-scale, intensive, and specialized production methods. Sow feeding management is a key link in pig production, and the feeding management of first-born sows is an important key point. The dietary nutrition level of first litter sows not only directly affects the feed intake of first litter sows during lactation and the production performance of suckling piglets; The update eliminated the turnover rate. [0003] The feeding of first litter sows is different from that of multiparous sows, and their nutritional needs are different from those of multiparous sows. First litter sows are usually mated at 200 days of age and weigh about 120kg, but their body development is immature,...

AI Technical Summary

Problems solved by technology

However, the first-litter sows selected for breeding now have the characteristics of thin backfat and fast growth. Therefore, it is difficult to ensure the fat reserves required for breeding first-litter sows, and it is necessary to improve the nutrition of the first-litter sow feed levels without being able to use the same diet as sows

This leads to the phenomenon of high primiparous stress, low feed intake, and poor disease resistance in the first litter sows, and the phenomenon of short service life and high elimination rate
