Embodiment 1

[0024] A breeding method for improving the lambing rate of Boer goats, comprising the following steps:

[0025] (1) Preferable ewe lamb: the selected ewe lamb is in good health, and its female parent is a ewe with the first twins;

[0026] (2) Management of ewe lambs after weaning: feed 75% leguminous forage, 24% concentrate feed and 1% premixed feed, the total amount of feeding is 3% of ewe lamb's weight, and the premixed feed contains 4% Sophora japonica extract, 1.2% ramie root powder, 0.8% medicinal thenardite and 94% carrier, keep enough drinking water, add 0.2% miracle fruit extract to drinking water;

[0027] (3) Management of ewes one month before mating: feed 67% leguminous forage, 30% concentrated feed and 3% premixed feed, and the total amount of feeding is 3.2-3.5% of ewe's body weight, of which pre-mixed feed The mixed feed contains 2% angelica extract, 3.2% ramie root powder, 1.2% mung bean extract, 0.6% medical thenardite and 93% carrier, keep enough drinking w...

Embodiment 2

[0034] A breeding method for improving the lambing rate of Boer goats, its ewes produce single births, and the postpartum management is as follows, and other breeding methods are the same as in Example 1:

[0035] 1 month postpartum management: feed 80% juicy feed, 18% concentrated feed and 2% premixed feed, the total amount of feeding is 6% of the ewe's body weight, and the premixed feed contains 1% angelica extract Ramie root powder, 2% ramie root powder, 2% kava extract and 95% carrier, keep enough drinking water, the drinking water is clear water, and the water temperature is not lower than 40 ℃.

[0036] In a breeding farm in Anhui, weaned lambs were selected and managed according to the above methods in spring ewes. The number of experiments was 20, and the experiment period was 30 months. The ewe lambs were in estrus for the first time at the age of 5 months, and different ewes The estrus period is within 8 days before and after mating. One month before breeding, the av...

Abstract

The invention discloses a breeding method for increasing a Boer goat lambing rate. The breeding method includes steps: optimal female lamb selection, after-ablactation female lamb management, female goat management one month before mating, early-gestation management, management two month before parturition, management one month after parturition, transitional period management and later-period management. Compared with the prior art, the breeding method has the advantages that by optimal selection and management method optimization according to physiological features of the female goats at different stages, the female lambs quickly grow to adult female goats being excellent in physical energy and uniform in oestrus, gonadotropin secretion is promoted, and conception rate and double lamb bearing probability are increased beneficially; compound juicy feed is adopted for conditioning after lambing, and after traditional period management, next-time mating can be carried out; due to appropriate nutrient addition in a management process, the female goats are kept healthy, and the average lambing rate is up to 260-280%, so that economic benefits of farmers are increased evidently.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a breeding method for improving the lambing rate of Boer goats. Background technique [0002] Boer goat is known as the "King of Meat Goats". It is a famous goat that produces high-quality lean meat in the world. Delicacy, adaptability and other characteristics, with the improvement of people's demand for mutton quality, Boer goats have also begun to be raised on a large scale. But because after giving birth, due to improper management, usually can influence the lambing rate of Boer goat, in order to improve lambing rate in prior art, generally can carry out drug injection, like this not only may influence the health condition of Boer goat parent, long-term The use will also produce drug resistance, and cannot effectively and continuously solve the problem of lambing rate of Boer goats. Contents of the invention [0003] The purpose of the invention ...
