High-quality Meat Goats Efficiently Feed Three Links

Parental choice

The father's choice of father should choose a large individual, fast growth, a wide range of recipes, high feed rewards, good meat performance and meat quality, high slaughter rate, adaptability varieties. At present, the goat parent breed is dominated by goat breeds such as Bol, Nubi, and Saeng.

The female parent should choose a variety with a large number, wide distribution, moderate individuality, high reproductive rate, strong lactation, good motherhood, resistance to roughage, and strong adaptability.

Hybrid pattern

Scientific combination and reasonable collocation are the key to the development of high quality meat goats. Commonly used hybrid combinations are binary hybridization and three-way hybridization.

The binary hybrid female parent is a local goat, and the male parent is a hybrid combination of a foreign goat breed or a local breed called a binary cross. The establishment of this model of a good-faith system is relatively simple, and only the local ewes need to be purified and selected. Individuals with large body size, lots of litter size, and high reproductive rates should be selected and cultivated as female parents, and then introduced foreign species or local varieties should be used. As a male parent, the hybrid combination can significantly improve the production performance of the offspring commercial sheep, the short cycle of hybrid improvement, the large number of ewes, and relatively extensive feeding and management, and is suitable for small-scale farming in rural areas, facilitating large-scale promotion. Commonly used combinations of hybrid models include: wave ♂ ♀ ♀ ♂, ♂ ♂ ♀ ♀, ♂ ♂ ♂ ♀ ♀ ♀.

The female parent of the three-way hybrid is a local goat, the first male parent uses a foreign goat breed, and the second male parent uses another exotic goat breed. This model has a remarkable effect of crossbreeding and improvement, but the establishment of a complex system is more complicated. It is necessary to cultivate a binary ewes first, then a second hybrid to develop commodity sheep, and a high requirement for breeding and management. This is mainly suitable for large-scale sheep farms and large sheep-raising households. . Generally choose large size, fast growth, high birth rate, high reproduction rate, good lactation performance, strong adaptability, such as Nubi, Saanen exotic breeder or dominant local breed as the first male parent, choose large size and grow. Fast goats with good meat production performance and high slaughter rate are the second male parent. Its three-way hybrid combination model includes: Bosuan (Nuojiu Bengbu) and Boshun (Saiji Bengbu).

Supporting scientific and efficient feeding technology

"Good breeding method, scientific breeding" is the technical guarantee for the development of high quality meat goats. The scientific feeding technology for high quality meat goats can be summarized as "seven changes":

Reformed flat-raised housing for sheep-raised houses is a sheep house, elevated sheep bed, forage grass, feed trough and sink. Feeding, drinking, resting, and excreting are all four ways for the sheep to segregate the sheep's body and forages. This way, it can reduce the intensity of daily labor management, avoid the pollution and waste of forage, improve the feeding condition of the flock, and reduce the number of sheep. Group mortality.

Rehabilitation is mainly supported by captivity, grazing is assisted by the release of a small amount, goats have a low weight gain, and management is difficult. After being replaced by captive breeding and supplemented by grazing, it is easy to scientifically manage the sheep, increase the amount of breeding, and expand the scale of breeding.

Rehabilitative group breeding Feeding herds into groups should establish a reasonable population structure and group rearing by species, male and female, and size. It is advisable to use 10 to 15 commercial sheep captive populations, and the stocking density is 0.8 square meters/only to 1.2 square meters/piece to ensure that the sheep grow evenly.

Changing a single forage to a variety of feeds According to the nutritional needs of goats at all stages of growth, reproduction, and fattening, a feed ration model of “Forage + Treating Straw + Concentrates 10 Additives” is used, and a reasonable mix is ​​formulated to provide a comprehensive full-priced diet. grain.

Changing the direct feeding of straw for processing and utilization By silage, micro-storage and ammoniation of straw, the nutritional value and palatability of straw can be improved. In this way, it can not only solve the forage grass of goats, but also increase the utilization rate of crop straw.

The natural growth of Lambs was listed as fattening. According to the characteristics of fast growth and development of hybrid sheep, lambs were pre-weaned and supplemented early. Commercial sheep fattening period (before listing, 45 days) according to different varieties, different seasons, different forage quality appropriate supplementary feeding, for rapid fattening. Concentrates are prepared from corn, barley, bean cake, bran, etc. The amount of feed is adjusted according to different seasons, forage varieties, moon age, and quality. Generally, the daily feed amount is 80 to 150 grams.

Change the single insecticide for comprehensive prevention and control of the epidemic. Regularly clean the inside and outside of the sheep house, and disinfect it regularly with bleaching powder and 100 toxins. In the spring and autumn season, the breeding goats use the broad-spectrum anthelmintic drugs such as disometamin, levamizole and trichlorfon to insect insects inside and out, and use the triple or five-joint seedlings according to the epidemic situation of the local flocks for regular or not. Regular epidemic prevention. For the fattening sheep, the insects can be dewormed once at 2 months old with the insecticide.
