Winter Fattening Measures and Techniques

First, the sheep sheep fattening winter should follow the basic principles (a) fattening group principle. All the male and female lambs that are not used for breeding and old, weak, thin, and remnant sheep that are eliminated can be used as fattening. First, they are castrated, dewormed, exterminated, and hoofed. Then they are grouped and grouped according to their age, strength, and strength. In this way, it is conducive to the stability of the sheep and the growth and development of the sheep. However, in general, young sheep gain weight faster than older sheep and have a good fattening effect. Lambs grow at the fastest rate from 1 to 8 months of age, and mainly grow muscles. Weaning lambs are selected as fattening sheep, and the fat lamb produced has good meat quality and high efficiency. Therefore, after the lambs are identified as weaned, the lambs that are not suitable for planting are grouped according to sex and body weight, and then grouped. The adult sheep that are eliminated are grouped and fattened according to their age and body weight. It facilitates the deployment of feed based on different conditions for nutritional requirements.
(b) highlight the principle of efficiency. The size of economic benefits is the key to measuring the success or failure of mutton sheep fattening, rather than blindly pursuing the maximization of daily gain. Especially under the conditions of house feeding and fattening, maximizing the weight gain of mutton sheep is often based on high-concentrate diets. Maximizing daily weight gain of mutton sheep does not necessarily mean obtaining the best economic benefit. Therefore, when setting the expected fattening intensity, we must use the best economic efficiency as the only measure. The production should be based on the standard of feeding, combined with the growth and development characteristics of the fattening sheep, to determine the dietary composition of the sheep, the amount of dietary supplies or the amount of supplements, and combined with the actual weight gain effect, timely adjustments.
(3) The principles of house feeding and fattening. When the temperature is low or the grassland, grass slopes and fields are frozen by ice and snow, the sheep can be changed from grazing to fattening. To feed high-quality dry grass or silage, feed a certain amount of corn, dried sorghum, sorghum, bean cakes and other concentrated feeds each day, and also feed some carrots, pumpkins, and other juicy feeds to increase palatability and increase sheep's production. Food intake. Allowing sheep to eat well in warm sheep houses can enable them to grow rapidly and increase their long meat.
(D) The principle of timely slaughter. Production should be organized in a rational manner, and fattening sheep should be slaughtered in due course. According to the growth and development stage of sheep fattening, the length of the fattening period is determined, the effect of over-shortening of fattening is not obvious, and if the length is too long, the feed conversion rate is low and economically unfavorable. Therefore, when the meat sheep reach a certain weight after a certain period of time, it must be slaughtered or marketed in time, instead of blindly pursuing the maximum weight of the sheep.
(e) The principle of scale determination. The size of fattening determines the amount of profit. Generally speaking, the larger the scale, the greater the profit. However, in actual production, it is often counterproductive. Due to the size of covetousness, it neglects the operation of the market and the carrying capacity of consumers, resulting in large-scale losses. The big consequences. Therefore, when determining the scale of fattening, the first is to understand the level of meat consumption at the place of sale and personal income, and to make a reliable forecast of the pre-sale price; the second is to pay attention to the price of agricultural products related to animal husbandry, such as corn, Soybeans, etc., the price of these products directly affect the fluctuation of feed prices, but also a barometer of the price of meat; Third, according to the amount of stored forage, feed, total amount, determine the length of fattening period and batch. Usually, the fattening period is 60-70 days with a reasonable and scientific combination of forage and feed. The length of time for sports fertilizers should be determined by the sheep's lyrical condition, size, and daily weight gain rate. Angle analysis, the best fattening period does not exceed 90 days.
Second, the sheep fattening winter fat should pay attention to several issues (a) pay attention to reasonable feeding timing, quantitative, fixed temperature, set the quality, and less to add ground feed, a variety of forage and feed mix and feed, to ensure daily growth of fattening sheep The nutrient needs, as far as possible to achieve a single feed, requires the mixing of forage and feed added on the day to be mixed, and never feed on the rotten spoilage and frozen feed. Feed a certain feed for a long period of time, taking care to prevent metabolic diseases caused by it. Adding a booster agent requires the use of low-toxic, easily excreted substances such as rumen.
(b) Pay attention to observation. Before the fattening, special training is required for the breeder to make him master the basic breeding knowledge and production essentials. During the production, attention should be paid to observing the condition of the sheep's feed intake, whether the rumination is normal, whether the mental condition is good, and whether the reaction to the noise is sensitive. Early detection and early treatment of diseased sheep.
(C) pay attention to regular weighing. Choose the same batch and the same level of sheep to sample and weigh, timely understand the weight gain situation of the fattening sheep, and accurately grasp the feed rate, generally about 15 days as a cycle, in order to grasp the monthly cost input and fattening rate of daily growth, Adjust feed supply at any time. Understand the number of sheep that can be slaughtered and achieve timely slaughter.
(d) pay attention to the maintenance of the barn. Before winter, it is necessary not only to repair the pens, to prevent the intrusion of thieves, but also to achieve "one, two, three, and four." “One Guarantee” is to ensure that the pens are clean and dry and warm. The “two use” is to use warm water to drink sheep and use hay washers. “Three Noes” means that the pens do not enter the wind, do not leak rain, and are not humid. It is the community that is grazing the grass, diligently changing the grass, diligently cleaning, and diligently removing the excrement.
(e) pay attention to disease prevention and treatment. The disease prevention and control of fattening sheep should adopt the principle of prevention as the mainstay and combine feeding and management with disease prevention and treatment. The first is to do a good job of disinfection. The sheds are to be cleaned and limed, and the sheep sheds, feeding trough and surrounding environment are sterilized with 2% formalin or 2% sodium hydroxide solution. Regular disinfection of sheep sheds and feeding troughs should be conducted regularly. Disinfection is carried out on the strip body; a disinfection pool is set up on the entrance of the field, and the vehicles entering and exiting the area must be disinfected. The second is that daily feeds and drinking water must be kept clean. They should not drink cold water and dirty water, and they should not let the sheep drink water on an empty stomach. The third is to carry out preventive injections on a regular basis. It is necessary to inject foot-and-mouth disease vaccines, goat pox vaccines, and sheep triple vaccines. Fourth, after the meat sheep are bred, the range of activities will be smaller, which will easily cause wet conditions in the housing and cause the occurrence of parasitic diseases. Therefore, attention should be paid to the environmental sanitation, ventilation and moisture prevention of the sheep house, and to prevent parasitic diseases such as sheep lice. The prevention and treatment. The fifth is to allow the sheep to regularly drink 0.1% potassium permanganate solution, depending on the number of drinking. Sixth, it is necessary to prevent the studs from staggering each other, and there should be good protection between the columns so as to prevent the spread of diseases caused by strings. Seventh, we must pay close attention to changes in the weather and take precautions as early as possible to prevent the sudden fall of winds and cold currents leading to the disease of the sheep.
