Breeding method for increasing ewe lambing rate of Boer goats

Abstract

The invention mainly relates to the technical field of ecological breeding, and discloses a breeding method for increasing the ewe lambing rate of Boer goats. The method includes the steps of earthworm supply, growth promotion, breeding sheep polyculture, breeding sheep separated culture, artificial insemination and ewe management. The breeding method for increasing the ewe lambing rate of the Boer goats in high-altitude areas is simple, the physique of ewes can be basically improved, the pregnancy capacity of the ewes is improved, the ewe lambing rate is naturally increased, the average lambing rate reaches 294%, and the breeding efficiency of the Boer goats is obviously improved. In spring, stocking areas of breeding sheep of the Boer goats are defined in the high-altitude areas, variouskinds of forage are rich in nutrient, and feeding of the breeding sheep is facilitated; then earthworms are put in the stocking areas, so that soil loosening in the high-altitude areas is promoted, and the growth of the forage is accelerated.

Description

technical field [0001] The invention mainly relates to the technical field of ecological breeding, in particular to a breeding method for improving the lambing rate of Boer goat ewes in high altitude areas. Background technique [0002] Boer goat is native to South Africa and is known as the "King of Meat Goat" in the world. It is a famous high-quality lean goat in the world and an excellent breed of meat goat; Boer goat is large in size and grows fast; Strong strength, more lambs; high slaughter rate, more meat; tender meat, good palatability; resistance to rough feeding, strong adaptability; strong disease resistance and genetic stability, so the demand for Boer goats is very high. However, the lambing rate of Boer goats is only 190~230% at present, and the breeding efficiency is low, especially in the high sea wave area with an altitude of 300~1000m. [0003] Existing patent document CN 104542458 A discloses a kind of ecological breeding method of Boer goat, in order to ...

[0002] The Boer goat is native to South Africa and is known as the "King of Meat Goats" in the world. It is a famous high-quality lean goat in the world and an excellent breed of meat goat. Strong force, more lambs; high slaughter rate, more meat; tender meat, good palatability; rough feeding resistance, strong adaptability; strong disease resistance and stable genetics, etc., so the demand for Boer goats is very high Large, often in short supply, but the current lambing rate of Boer goats is only 190-230%, and the breeding efficiency is low, especially in high-altitude areas with an altitude of 300-1000m

[0003] The existing patent document CN 104542458 A discloses an ecological breeding method for Boer goats, which is to increase the growth rate of Boer goats and shorten the breeding time, but the lambing rate of Boer goats is about 206%, which will not be significantly improved. Lambing rate of Boer goats; patent document CN 105766792 A discloses a breeding method for Boer goats. The ewes are treated 15 days before breeding, and the short-term treatment has little improvement in the ewes' physique. Even if the number of embryos is increased by drug hormones, it will have an adverse effect on the health of the embryos and postpartum lambs, affecting the survival rate
