Problems solved by technology

Due to factors such as lack of breeding technology, nutritional deficiencies, and diseases, female donkeys usually have a successful pregnancy in the second to fourth estrus period, and even repeated infertility, and the survival rate of donkey foals is not high, so the interval between foals is longer
Female donkeys give birth once a year and a half or two years, and most of them only give birth to one foal. The overall reproductive rate is low, which affects the development of the donkey industry
[0004] In order to improve the reproductive rate of female donkeys, the method used in the prior art is mainly to increase the amount of concentrated feed in the feed. This single method is not effective and it is difficult to obtain ideal results.

Embodiment 1

[0035] A breeding method for donkeys in the northern agro-pastoral staggered belt, which includes:

[0036] The stages of staged rearing are divided into four stages: 1-3 months of gestation, 4-9 months of pregnancy, 10 months of pregnancy to the 15th day before the expected date of delivery, and 15th day before the expected date of delivery to the date of birth of the foal. Among them, the refined feed for 1-3 months of pregnancy accounts for 18% of the total weight of the diet, and the protein content of the whole diet is 11.1%; the refined feed of 4-9 months of pregnancy accounts for 24% of the total weight of the diet, and the protein content of the entire diet is 11.4%; the refined feed of the 10 months of pregnancy to the 15th day before the expected date accounts for 29% of the total weight of the diet, and the protein content of the entire diet is 11.7%; from the 15th day before the expected date to the date of the colt, the total weight of the diet is reduced by 30% compa...

Embodiment 2

[0067] A breeding method for donkeys in the northern agro-pastoral staggered belt, which includes:

[0068] The stages of staged rearing are divided into four stages: 1-3 months of gestation, 4-9 months of pregnancy, 10 months of pregnancy to the 15th day before the expected date of delivery, and 15th day before the expected date of delivery to the date of birth of the foal. Among them, the refined feed for 1-3 months of pregnancy accounts for 19% of the total weight of the diet, and the protein content of the whole diet is 11.2%; the refined feed of 4-9 months of pregnancy accounts for 25% of the total weight of the diet, and the protein content of the entire diet is 11.5%; the refined feed of the 10 months of pregnancy to the 15th day before the expected date accounts for 30% of the total weight of the diet, and the protein content of the entire diet is 11.8%; from the 15th day before the expected date to the date of the production of the foal, the total weight of the diet is re...

Embodiment 3

[0099] A breeding method for donkeys in the northern agro-pastoral staggered belt, which includes:

[0100] The stages of staged rearing are divided into four stages: 1-3 months of gestation, 4-9 months of pregnancy, 10 months of pregnancy to the 15th day before the expected date of delivery, and 15th day before the expected date of delivery to the date of birth of the foal. Among them, the refined feed for 1-3 months of pregnancy accounts for 20% of the total weight of the diet, and the protein content of the whole diet is 11.3%; the refined feed of 4-9 months of pregnancy accounts for 26% of the total weight of the diet, and the protein content of the entire diet is 11.6%; the refined feed of the 10 months of pregnancy to the 15th day before the expected date accounts for 31% of the total weight of the diet, and the protein content of the entire diet is 11.9%; from the 15th day before the expected date to the date of the colt, the total weight of the diet is reduced by 35% compa...

Abstract

The invention discloses a method for raising donkeys with interlaced farming and animal husbandry in northern China, and belongs to the technical field of livestock raising. The technical scheme adopted by the present invention to solve the technical problem includes the following steps: feeding pregnant female donkeys in stages, adopting the mode of "house feeding + grazing + health care"; feeding lactating female donkeys in stages, adopting "house feeding + extended grazing" +Health care” mode of feeding; newborn foals suck colostrum first, and from the 6th day to 6 months after birth, adopt the “breastfeeding + breast substitute” mode of feeding; the foals are weaned after 6 months of age, and the weaned The latter foals are raised in the mode of "house feeding + grazing + health care". The feeding method provided by the present invention adopts stage-by-stage feeding during the gestation period and lactation period of the female donkey, fully considers the needs of the growth and development of the donkey foal in different stages, and improves the survival rate of the donkey foal after birth; Supplementing milk replacer powder at 6 days can effectively guarantee the growth and development of donkey foals after birth and improve the survival rate of reproduction.

Description

Technical field [0001] The present invention belongs to the field of livestock breeding technology, in particular to a breeding method of a northern agricultural and pastoral staggered donkey. Background [0002] Donkeys are single-stomach herbivores, mild temperament, easy to tame, strong endurance, small stride, fast pace, excellent pulling force, long continuous labor life, with excellent service performance. Donkey meat is delicious and delicious, the meat is tender and juicy, and has therapeutic and health effects. Donkey skin is the only legal raw material for the production of traditional Chinese medicine ejiao, which has important medicinal value. The composition and protein contained in donkey milk are close to human milk, and have the characteristics of low fat, high milk protein and high lactose. Short donkeys and miniature donkeys can be used as companion donkeys due to their small and docile bodies. Donkeys are resistant to disease, tolerant to rough feeding, and pre...
