Small Tail Han Sheep Breeding Management Technology

November 28, 2019

Small-tailed sheep breeding management should pay attention to the following aspects:

First, scientific breeding rams: nutrient requirements during the breeding period full price, palatable, easy to digest. Rich in protein in the diet, the ram has a strong sexual function, a large amount of seminal fluid, strong sperm motility, a high density, and easy quaternization for breeding. 80 to 100 kilograms of male rams, 1.5 kilograms of concentrate per day, quality hay to feed, 1 kilogram of juicy feed. On the non-breeding date, concentrates and succulent feeds are reduced by one-third each, and the medium nutrient level can be maintained.

Ewe: Different physiological stages require separate materials. Under the planned lambing situation, the ewes after weaning have an empty period of positive value when the grass is flourishing. Generally, they do not make up forage, and they can restore their constitution only by doing a good job of grazing. From the first half of the breeding season, appropriate feeding may be appropriate to promote ovulation of the ewes. Pre-pregnancy fetus needs less nutrition, and it is also a feeding season. After grazing, only a small amount of feed can meet the nutritional needs. After one hundred days of pregnancy, the fetus develops rapidly and the ewes need to accumulate nutrients. In addition to grazing, daily supplements should be about 0.4 kg of concentrate, 1.5 kg of juicy material, quality hay to meet needs, and appropriate amounts of salt must be fed. And bone meal. In the plain farmland, there is no need to put pastures in place, and it is necessary to intensify exercise. The amount of concentrate and juicy ingredients in the diet will increase by one third. Nursing ewes fed 0.5 kg of concentrate per day, 1 kg of juicy material, and sufficient quality of hay. In the late lactation period, lambs will eat grass and eat ewes. Ewes can be fed properly. If there is insufficient nutrition, feed a small amount of concentrate.

Lambs: Within one month of age lambs are mainly breast-feeding. After the first month of age, lambs gradually feed on food, supplemented by breastfeeding. The lambs can be weaned after two months. The lambs after weaning should be easy to digest, palatable, and rich in nutrition. Weaning should continue feeding for three weeks during weaning, and about 0.3 kg of concentrate should be fed daily. Youth rams should be raised slightly higher than ewes.

Second, management

1, the main attention to the following points: (1) species of rams fed alone. Massage the testicles daily during the breeding period, weigh regularly, fix the hoof, cut the eyelids, and don't feed before the seeds are mixed. (2) Diligently check the estrus condition of the ewe's sheep to prevent misalignment. (3) For gravid ewes banned, anti-fighting, banned eating ice grass and ice. (4) Pay attention to ewe lambs hygiene and dirt removal, and often check the breast status of nursing sheep. (5) Strengthen lamb care. Ensure that the lamb eats colostrum, and if necessary, carry out manual nursing or find a nanny sheep for feeding. Pay attention to the health status of the lamb. (6) The grounds of the pens shall be kept clean, dry, well ventilated, with proper sun exposure and moderate temperature. Trough, sink clean. Grass, water and materials are clean to prevent fodder poisoning. Pay attention to grazing security. Timing hoof, shearing, castration.

2. Breeding and breeding seasons and initial mating age: Small-tailed Han sheep breeding is mostly carried out in autumn and winter. Ewes have more estrus between August and October. Rams have no significant mating season, but autumn is the climax of sexual activity. Ewes are estrus 4 to 6 months old and can also be bred, but as a breeding ground, it is advisable to reach the age of full. The ram is 1.5 years old as the best breeding age. Male and female ewes should not be mated prematurely. Estrus and Pregnancy: The estrus cycle of the ewes is about 18 days, and the duration of each estrus is about 30 hours. Ovulation begins late in estrus. 12 to 24 hours after estrus is easy to fetus. Normal ewes no longer have estrus after conception. The average period of pregnancy is 150 days. If you want to have an annual output of two children, you can do it at the right time in April and early October of that year.

Delivery and lambing: The ewes in the pregnant ewes are significantly enlarged on the 15th day before delivery, and the breasts are ruddy and plump, and the vulva swollen slightly. 2 to 3 days before delivery, the nipples are straight, and the breasts can extrude a small amount of yellow milk. About one day before delivery, the muscles of the ewes' tails were significantly concave. Frequent supineness, frequent urination, vulva discharge mucus and constant anger and tweet. The lambs are laid within half an hour after rupture of the amniotic membrane.
