Spend feeding for fattening method.
Background technology
China is sheep raising big country of the world, and sheep breeding stock is 1.58 hundred million within 2014, accounts for China's sheep breeding stock
52.15%.Sheep lamb because meat is good, meat tenderness is tasty, fragrant odour, without smelling of mutton, and have benefiting qi and nourishing blood temperature reason etc. function and
It is standby to get consumer reception.Horizontal higher than international market but lamb holds at high price in recent years, one of major reason is
Sheep raising technological lag have impact on the development and mutton supply of industry.
Sheep cultivation is concentrated mainly on northern China, especially pastoral area, prohibits with the development and country of grassland deterioration
The policy for herding drylot feeding is encouraged, and northern area continues to bring out out plant and the breeding enterprise of scale, embodying sheep husbandry just
Cultivated from tradition to modernization, changed from free-ranging to the direction of scale and intensive culture.In these gratifying phenomenons behind,
But fattening technology backward technology bottleneck and the low objective reality of culture benefit are faced with.Such as mutton sheep dressing percentage, carcass weight,
Individual meat yield has a long way to go compared with Foreign Advanced Lerel, and the lamb of high-quality high-grade is few.For another example, although confined farming
It has been begun to take shape that, but management style is still very extensive, had the sheep husbandry of nearly half still in traditional supplement of feed under grazing condition pattern,
Size male and female is mixed group feeding and supported, even the feeds utilized nutritional imbalance of confined farming, feed conversion rate is low, and feed species mistake
Protruded in phenomena such as single, herbage quality is poor, the cooperation not science of daily ration, cause to deliver cycle length for sale, it is low in economic efficiency.Simultaneously
Mutton meat is rougher, and intramuscular fat precipitation capacity is less, and mouthfeel is poor.
