Breeding sheep breeding methods and precautions

I. Construction of sheep shed for breeding sheep

Sheep sheds should be ventilated, sunny and dry, with a suitable ambient temperature of 18-20℃. The general ram's enclosure is a single pen for breeding, and should ensure that each ram occupies an area of 1.5-2.0 square meters, so as to prevent the decline of sexual reflexes of rams caused by the mixing of males and females, but also to avoid mutual fights between rams and the consumption of physical strength, and the ram's house should be far away from the ewe's house, to avoid the impact of the foraging.

The enclosure material should also be strong, because some rams have greater strength, if they smell the odor of the ewe in heat, they will jump the fence, resulting in promiscuous mating. The area of the sports ground should not be less than 2 times of the area of the sheep shed to ensure the proper movement of the rams.

Breeding sheep selection

1. Selection principles

In the selection of breeding sheep, it is necessary to choose those rams whose appearance is in line with the characteristics of the breed, and whose spirit is vigorous and robust, especially pay attention to the observation of reproductive organs and eliminate single testes and cryptorchid rams.

Secondly, the selected rams should be identified by genealogy, and individuals whose ancestors have hereditary diseases and inbreeding cannot be selected.

2. Selection method

When selecting rams, it is necessary to adopt the practice of keeping many selected rams. After purchasing a number of lambs, two screenings are carried out, the initial screening at 3 months of age when weaning, selecting those individuals with good physical development, and then the second screening at 6 months of age, selecting those individuals with fast average daily weight gain and obvious secondary sexual characteristics, which mainly refers to the testicles of the rams to be well-developed.

Staying more selected has its advantages, the rams selected by themselves grew up in the farm, and are very adaptable to the environment of the sheep farm, which also means that when the rams enter the breeding period, there is less stress and the good index of the progeny will be higher.

Feeding and Management of Breeding Rams

1. Adopt suitable feeding methods: Combine the local climate characteristics, nearby pasture resources and the actual feeding situation of the farm to choose suitable feeding methods and do a good job of staged feeding. In the spring and winter when the temperature is low and there is a lack of pasture, the supply is seriously insufficient, this period is not suitable for grazing and feeding, so this stage should be taken to feed in a sheltered way, in order to provide sufficient nutrition for the breeder. Every morning and evening feeding grass, but also in good weather for a moderate amount of grazing, the main purpose is to increase the amount of exercise of breeding sheep, in order to enhance physical fitness, to maintain better fertility; in the season of pasture greening can be chosen to house-feeding and grazing feeding mode, in the morning and afternoon grazing, noon and evening rest, after the collection of grazing should pay attention to the supplemental feeding, in order to make its intake of comprehensive and adequate nutrition. In the season of abundant pasture and good climate, you can choose to feed by complete grazing and reduce the amount of supplemental feeding in order to reduce the cost of production. But even so, the amount of supplemental feeding should be carried out according to the different stages of meat goats at night rest.

2. Combined group: different physiological stages of breeding sheep should be divided into groups, according to the production requirements of the breeding flock can be divided into rams, empty ewes, pregnant ewes, lactating ewes and reserve ewes, in order to facilitate the management of the different physiological stages of the breeding of sheep according to the nutritional requirements of the provision of appropriate feed, but also to avoid the phenomenon of breeding, fighting, and can be effective in maintaining the order of the group.

3. Scientific and reasonable provision of feed: feeding meat breeder sheep feed requirements of comprehensive nutrition and rich variety, mainly forage and concentrate feed, while with the feeding of silage, silage is mainly processed from corn and other crop residues or pasture, hay is dry straw or dry pasture, concentrate feed can be used for breeder special premix, or can be processed and prepared by themselves. According to the different physiological stages of the meat breeder sheep in the scientific and reasonable provision of feed, generally empty ewes, reserve ewes and pre-pregnancy ewes can be used with the same feed formula, lactating ewes and pregnant ewes use the same feed formula. The supply of concentrate feed should be put according to the body weight of meat breeding sheep.

Breeding sheep breeding precautions

1. Pregnant ewes should be fed lees carefully. Pregnant ewes should not be fed feeds that are too acidic or contain alcohol, such as white wine lees and silage, or they will be prone to abortion, weak lambs and other problems.

2. Ewes should not be too fat. Under the condition of housed feeding, if you feed too much and the ewes lack of exercise, it will cause the ewes to be too fat to affect the normal reproduction, and it will be easy to have the problems of delayed oestrus, mating difficulties, low fertility, and production difficulties.

3. Separate the male and female pens and keep good records. Breeding males and females in separate pens as much as possible can avoid inbreeding, make full use of breeding sheep, and keep good breeding records. Good breeding records can be a good projection of the ewe's due date, to ensure the survival rate of lambs.

4. Postpartum ewe care. After giving birth, give the ewes brown sugar bran soup in time to replenish water, provide energy, rationalize the intestinal tract, and observe whether the fetal coat is normally discharged, if it is not normally discharged, it needs to be injected with uterotonin, and anti-inflammatory drugs are injected for 3 consecutive days, which can effectively prevent the ewes from developing postnatal inflammation.
