Problems solved by technology

[0004] Modern sows spend most of their production time in the positioning pen, which limits the activities of sows and affects their physical fitness
In addition, the current batch timed insemination process for sows expects to obtain more litter size by promoting follicle development, resulting in increased stress in sows in late pregnancy
These all have a negative impact on the labor process of sows during farrowing. At present, there is no effective method to alleviate it.

Embodiment 1

[0022] 1. Test animals and additives

[0023] The sows are Dan line grown-up binary sows with 3-4 parity. Glucosamine (Glucosamine, GlcN) selected for the test in this example is a food-grade raw material with a purity of 99%, purchased from Zhengzhou Kangyuan Chemical Products Co., Ltd.

[0024] 2. Grouping and handling of sows

[0025] The production process of the pig farm is batch production. According to the production process, one batch is selected to carry out the test. The sows of this batch are randomly divided into 4 treatment groups according to the stalls in the breeding house, and each group of pigs is subjected to 1 treatment. , 4 treatments were: control group (without adding GlcN), 18 g / head / day GlcN group, 24 g / head / day GlcN group and 30 g / head / day GlcN group, the addition time was at the end of pregnancy One month (85 days of gestation to parturition), GlcN was added to the hopper using a measuring cup, and entered into the trough at the same time as the fe...

Abstract

The invention provides application of GlcN in shortening the birth process of female animals. And in the last month of the pregnant female livestock, adding the glucosamine into the feed every day according to 18-30g per female livestock per day, and feeding the female livestock with the glucosamine per female livestock per day. The invention provides a novel application of glucosamine, and the glucosamine is used for shortening the delivery process of female animals, shortening the delivery time of the animals, reducing the probability of stifling caused by suffocation death of the animals in the delivery process in the process of staying in the birth canal, and reducing the death of fetuses.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to the application of GlcN in shortening the laboring process of female animals. Background technique [0002] Modern industrialized pig raising has extremely high production efficiency, with many sows littering (12-16 per litter), high physical consumption, frequent parity, short recovery interval, and great physiological pressure on sows. If the labor process is long during labor, it will lead to fatigue during labor, easy dystocia, and dystocia. It will also increase the degree of injury to the birth canal of the sow. If the labor process is too long, it will cause excessive physical exertion, acidosis, and cause fetal distress and even dystocia. Increased cesarean section rate and risk of delivery. How to effectively shorten the labor process is a technical problem that needs to be solved urgently. [0003] Glucosamine (Glucosamine, GlcN), molecular formula C 6 H 13 NO 5 ,...
