Breeding techniques of Duper Sheep

Dupo sheep breeding is favored by farmers because of its high yield. At the same time, how to breed and breed Dupo sheep is a great knowledge, so how to raise Dupo sheep well?

In the production of Dupo sheep, the use of improved breed hybridization can improve the lambing rate, lamb survival rate and body weight. As the male parent of hybrid Duper sheep (especially the terminal male line) must have the characteristics of early maturity, rapid growth and development, and the female parent should choose the improved breed with high fecundity and long estrous season. It is necessary to arrange the time of breeding and lambing in the northern part of our province, the environmental temperature changes greatly in April every year, and the lamb mortality rate is relatively high, so in production, we should try our best to arrange the lambing time from January to March to avoid the lamb being born in April. Do a good job in the feeding and management of pregnant ewes if ewes can get adequate and reasonable nutrition during pregnancy, the lambs will be big, physically strong, strong in disease resistance and easy to manage. Pay attention to the starting exercise of lambs, that is, they are allowed to eat high-quality hay or grass freely at the age of 10 days, and the mixed concentrate is free from the age of 20 days. The mixture should be based on digestible corn (2447, 6.00, 0.25%), wheat bran, plus fried soybeans (4798, 17.00, 0.36%), salt and trace elements, and avoid using vegetable cakes, cotton cakes and so on. It is necessary to provide clean drinking water and allow it to drink freely, especially in the high temperature season, the lambs should not be short of water, otherwise it will lead to loss of appetite, and the rumen of the weaned lambs will be fully developed when they are about 7 weeks old, and the roughage can be digested better. Previously weaned lambs cannot get enough nutrition only by eating roughage, preferably at the age of 3 months or so. Special care should be given after weaning until it fully adapts to the conditions of grazing or house feeding and then fattens and propagates.

During the breeding period, the ration of breeder ram raised in Duper sheep is 35% Mel 40% for Gramineae hay, 20% Mel 25% for succulent feed, 45% for concentrate feed, and 3 Mel for 4 times a day and 4 times for drinking water. Exercise for 6 hours per day. During the breeding period of Dupo sheep, ewes are responsible for mating, pregnancy, lactation and other tasks, and should maintain a good nutritional level, so as to achieve the purpose of multiple births, prolificacy, more life and more strength. During pregnancy, ewes should mainly protect their fetuses, forbid feeding moldy, spoiled and rotten feed, and forbid drinking cold water to avoid jumping, chasing and startling. Lactating ewes focus on the first two months, with twin-lambed ewes, supplying 0.6 ml 0.8 kg of concentrate, 1.0 kg of high-quality hay, 0.5 kg of carrots, and 0.4 kg of concentrate for single lambs, 0.5 kg of high-quality hay and 0.5 kg of carrots per day. During the breeding period, the growth and development of lambs is the fastest and the plasticity is great. The quality of raising will directly affect the growth and development of the lambs at this stage. After the lamb can eat feed, the feed diversification is required, and it is best to feed the formula as follows: corn 50%, wheat bran 20%, rapeseed cake 5%, soybean cake 15%, bone meal 2%, salt 1%, fish meal 4%, white sugar 2.5%, auxin 0.5%.
