Embodiment 1

[0024] 1. Materials

[0025] 1.1 Feed material glucosamine (purity ≥ 97%)

[0026] 1.2 Animals grow up dual sows (a large breeding pig farm in Beijing)

[0027] 2. Methods and results

[0028] 2.1 Experimental design

[0029] In the sow feeding experiment, 120 long-term white binary sows with the same age and parity were selected and randomly divided into 4 groups, 30 in each group. Each group is randomized to one of the treatments in Table 1. The feeding stage and addition amount of each group are shown in Table 1. The composition of the late pregnancy feed except grape aminoglucosamine is shown in Table 2. The sows in the gestation 85 to delivery stage are fed per head per day. The average feeding amount is 3 kg.

Abstract

The invention provides new application of glucosamine, and specifically provides application of the glucosamine as a feedstuff raw material in improving the production performance of livestock. The glucosamine feedstuff raw material used in the feedstuff of sows can improve the number born alive and the rate born alive of the sows without changing the average weight of newborn individuals, and especially, the glucosamine obviously improves the number born alive and promotes the reproductive efficiency of the sows; and the glucosamine can effectively improve the number born alive at weaning, the weight of litter at weaning and the average weight of individuals at weaning, and especially the glucosamine obviously improves the number born alive at weaning and the average weight of individuals at weaning, thereby increasing the economic benefit in feeding sows.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to the application of glucosamine to improve the production performance of livestock. Background technique [0002] Feed raw materials refer to feed substances (including carriers and diluents) that are derived from animals, plants, microorganisms or minerals and are used for processing and making feed but are not feed additives. There are many kinds of feed raw materials. In the process of designing and producing feed, those that are easy to obtain, low in cost, have synergistic effects and avoid antagonistic effects are often selected for feed preparation to ensure animal health and meet the requirements of animal health. Production needs. [0003] Glucosamine (GluN), a compound in which one hydroxyl group of glucose is replaced by an amino group, molecular formula C 6 h 13 o 5 N, also known as glucosamine. Glucosamine is an important component necessary for the synthesis of...
