Technical points of raising sheep in rural areas

(1) after weaning in time and reasonably dividing the lambs into groups at the age of 2 ~ 3 months, the mother and son should be weaned separately, which can quickly restore the physique of ewes and achieve the goal of early estrus, early mating, prolific and high yield. At the same time, exercise the lamb's ability to live independently in time. The weaned lambs are reasonably grouped and raised in circles according to male and female, size, strength and weakness, so as to prevent the strong ones from getting stronger and the weak ones from getting weaker, affecting the overall development level and uniformity.

(2) timely breeding and improving the reproduction rate of ewes refers to the determination of the age of the first mating of sheep and the time of mating after estrus. It is not only an effective way to improve the reproduction rate, high yield and high yield of ewes, but also the key to improve the efficiency of breeding. Sheep are generally bred for the first time at the age of 15 months. Early mating will affect the growth and development of ewes, thus reducing the reproductive performance of ewes. The time of mating after estrus: estrus in the afternoon, mating in the next morning, 8-12 hours interval, mating again. At the same time, it is necessary to make good breeding records to prevent unnecessary economic losses caused by mismatching or not remembering the date of delivery.

Reasonable preparation of forage feed is the basis for the success of large-scale farmers. Straw, seedling rattan and lotus husk rice straw of mature crops in agricultural areas contain a lot of lignin and poor palatability, but they are the main source of roughage for raising sheep in agricultural areas, which must be dealt with reasonably. It is necessary to correctly use the techniques of silage, ammoniation and alkalization to deal with crop straw, and it is strictly forbidden to feed mouldy forage grass and unclean ammoniated and alkalized forage grass due to improper silage. In the preparation of roughage, we should strictly prevent the coarse fodder from being powdered too fine. The production practice has proved that long-term feeding of over-fine roughage is easy to cause ruminating disorder and internal diseases such as forestomach relaxation, accumulated food, dysphoria and so on. The length of roughage can regurgitate normally when the length of roughage is 1cm or 3cm. The preparation of concentrate feed should be based on local feed resources, different sheep breeds and different growth stages. After preparation, the energy, protein, minerals and vitamins in the feed should meet the needs of growth, reproduction and lactation at different stages. The ratio of ammonia to sulfur in the feed should reach 7: 8 ∶ 1, and the ratio of calcium to phosphorus should reach 1: 2 ∶ 1. When feeding non-protein nitrogen feed, thiamine must be supplemented, otherwise it will cause the improper proportion of ammonia and sulfur in the rumen, which can not be effectively used by rumen microorganisms and can not achieve the desired goal.

(4) reasonable supplementary feeding to ensure the normal growth and development of sheep raising sheep in agricultural areas, mostly by the combination of house feeding and grazing. Especially in winter, it is generally based on house feeding, if not timely and reasonable supplementary feeding, it is difficult to meet the needs of sheep growth and development. Therefore, sheep raising in rural areas must provide reasonable supplementary feeding to the sheep. Supplementary feeding should depend on the season and the fat condition of breeding rams, ewes, adult sheep and lambs. Put an end to the phenomenon of sheep growing and losing weight for half a year, and ensure that the fat condition of the sheep is always in the middle and upper level. This is conducive to normal sheep breeding sheep due to the intake of a large number of undephenolized or improperly processed cottonseed cake and cotton leaves will cause poisoning. The disease mostly occurs in the main producing areas of cotton. If the cottonseed cake is added improperly in the feed, poisoning will occur. Haas.
