Problems solved by technology

Most of the previous research on this aspect was to increase the content of nutrients in sow feed, such as amino acids, vitamins, minerals, etc., but after so many years of development, these conventional researches have reached a bottleneck period. There is not much room for growth performance in piglets
At the same time, there have been more and more diseases in sows in recent years, and it is difficult to prevent and control them. The health of sows has become a bottleneck factor restricting the development of the pig industry.

Embodiment 1

[0017] A feed additive for sows for improving the weaning weight of piglets. The main components are chitosan oligosaccharide and maltodextrin, wherein the mass content of chitosan oligosaccharide is 10%, and the mass content of maltodextrin is 90%. The polymerization degree of the chitosan oligosaccharide is 2-10, and the mass purity is more than or equal to 85%.

[0018] Select 40 sows with similar parity and good health, and randomly divide them into two groups, namely control group and test group, with 20 sows in each group. The control group was fed with basal rations, and the basal rations of the test group were supplemented with 300 g / t full-price feed of the feed additive for sows of the present invention. The experimental period started at gestation day 86 of sows and ended when piglets were weaned at 20 days of age. The feeding and management of sows is carried out according to routine procedures. The test results are as follows:

Embodiment 2

[0028] A feed additive for sows for improving the weaning weight of piglets. The main components are chitosan oligosaccharide and maltodextrin, wherein the mass content of chitosan oligosaccharide is 20%, and the mass content of maltodextrin is 80%. Wherein the degree of polymerization of the chitosan oligosaccharide is 2-10, and the mass purity is more than or equal to 85%.

[0029] 40 healthy sows with similar parities were selected and randomly divided into two groups, namely the control group and the experimental group, with 20 sows in each group. The control group was fed with basal rations, and the basal rations of the test group were supplemented with 200 g / t full-price feed of the feed additive for sows of the present invention. The experimental period started from the 80th day of gestation of the sows and ended when the piglets were weaned at 20 days of age. Feeding management is carried out in accordance with the normal feeding and management methods of the farm. T...

Embodiment 3

[0038] A sow feed additive for improving the weaning weight of piglets, the main components are chitosan oligosaccharide and maltodextrin, wherein the mass content of chitosan oligosaccharide is 5%, and the mass content of maltodextrin is 95%. Wherein the degree of polymerization of the chitosan oligosaccharide is 2-10, and the mass purity is more than or equal to 85%.

[0039] A total of 197 binary mixed sows with similar parities were selected and randomly divided into two groups, namely the control group and the test group, with 98 sows in the control group and 99 sows in the test group. The control group was fed with basal rations, and the basal rations of the test group were fed with 500 g / t full-price feed of the feed additive for sows of the present invention. The experimental period started at gestation day 90 of sows and ended when piglets were weaned at 28 days of age. The feeding and management of sows is carried out according to routine procedures. The test resul...

Abstract

The invention relates to a sow feed additive for improving the weaning weight of a piglet and an application scheme of the sow feed additive, belonging to the field of animal feeds and being applied to the industry of livestock breeding. The sow feed additive for improving the weaning weight comprises main ingredients of 5-20 percent of chitosan oligosaccharide and the balance of maltodextrin. The application scheme of the sow feed additive for improving the weaning weight of the piglet specifically comprises the step: at a start of 80th-90th days of gestation of the piglet, after adding the sow feed additive in a diet of a sow, feeding the sow until the lactation is ended. In the application scheme, the addition amount of the sow feed additive is specifically as follows: 200-500g of the sow feed additive is added in each ton of the diet of the sow. The sow feed additive disclosed by the invention is simple in use method, and remarkable in weaning weight of the piglet.

Description

technical field [0001] The invention relates to a sow feed additive for improving the weaning weight of piglets and an application scheme thereof, which belongs to the technical field of animal feed and is applied to the animal husbandry industry. Background technique [0002] Suckling piglets are the fastest growth and development period in the life of pigs, and the weaning weight of piglets directly affects the subsequent growth and development of pigs. There is a saying in the industry, "weaning weighs 1 catty, and slaughter weighs 10 catties", which is enough to illustrate the importance of weaning weight of piglets to pig raising under the modern business model. Studies have shown that the feed nutrition status of sows during pregnancy and lactation will directly affect the growth and development of piglets before and after birth. Therefore, the quality of feeding and management of sows during pregnancy and lactation directly affects the growth of suckling piglets and ...
