Q & a Nubian black goat farming breeding technology

Q: when breeding sheep most suitable?

答:9月、10月是羊配种的好季节,因为山羊的妊娠期是152天,绵羊的妊娠期是150天,母羊如在9月、10月配种怀孕,可于翌年2月、3月产羔。其好处:一是气候逐渐暖和,青草也开始长出来,自然环境对母羊泌乳和保证羔羊成活极为有利。二是早春产的母羔,当年8~9月龄体重可达35公斤以上,10~12月又可配种。三是母羊按其生理规律产后第3个月进入泌乳高峰期,早春产羔可确保母羊在泌乳高峰期吃上刺槐叶和嫩青草,可提高母山羊的产奶量,增加经济效益。

Answer: September, October is a good season for sheep breeding, because pregnancy goat is the 152 day of pregnancy, sheep is 150 days, such as pregnant ewe in September October, breeding, be in next February, March lambing. Its advantages: one is the climate getting warmer, the grass is beginning to grow out of, the natural environment to the ewe lamb lactation and to ensure the survival of extremely favorable. Two is the early spring production of lambs, the year 8 ~ September weight up to 35 kg, 10 ~ December and breeding. Three is the ewe according to their physiological law postpartum third months into the peak of lactation, early spring lambing ewes can ensure that at peak lactation eat thorn Salvinia and tender grass, can increase the milk yield of goats, increase economic benefits.

问:羊配种前要做好哪些准备工作?

Q: sheep breeding what to do before the preparation work?

答:在羊的配种旺季到来前1~2个月要加强公、母羊的饲养管理。放牧羊要抓住秋季牧草结籽富含营养的有利时机延长放牧时间,让羊吃饱吃好,并补饲精饲料。舍饲羊比平时要增加30%~50%的精饲料,种公羊每天补喂胡萝卜250~500克,使羊只膘肥体壮,母羊发情正常、公羊性欲高,从而提高配种受胎率。与此同时,配种站(点)要备好人工授精器械,严格消毒,迎接配种。

Answer: in the sheep breeding season before the arrival of 1 ~ 2 months to strengthen the management of the public, ewe rearing. Sheep to seize the favorable opportunity of autumn grass seed nutrient rich extended grazing time, let the sheep eat eat, and supplementing feed. Feeding the sheep feed 30% ~ 50% increase than usual, ram up everyday with carrots 250 ~ 500 grams, the sheep are plump and sturdy., ewe, RAM normal sex, so as to improve the conception rate. At the same time, breeding station (point) to prepare artificial insemination equipment, strict disinfection, meet the breeding.

问:如何充分利用杂交优势?

Q: how to make full use of hybrid vigor?

答:利用两个品种进行杂交,如用 努比亚黑山羊 公羊配本地母羊产下的后代,生长发育快,体重比本地羊高,抗病力比 努比亚黑山羊 强,具有两个亲代的优点,有些优点还超过亲代,这种现象叫“杂交优势”。某羊场测定了200只 努比亚黑山羊 公羊配本地羊产下的杂交羔羊(公、母各半),平均初生体重为3.1公斤,4月龄体重为26.1公斤,分别比本地羊增加31.4%和74.1%,羔羊成活率达100%,比 努比亚黑山羊提高了5%。又据有关专家鉴定,以莎能奶山羊公羊配本地奶山羊,其所产的改良1~3代羊平均年产奶639公斤,比本地奶山羊产奶量增加107%,公羊育肥比本地公羊提高饲料报酬(以草料换来的肉、皮张)57%。所以,要根据经济类型的要求给羊配种,有计划地选种选配,避免近亲交配,以增加经济效益。

Answer: hybridization using two varieties, such as the use of Nubia black goat ram ewe with local offspring, fast growth, weight higher than native sheep, disease resistance than Nubia black goat is strong, with two parent advantages, some advantages of more than the parent, this kind of phenomenon is called "hybrid superiority". A sheep farm were determined in 200 only Nubia black goat RAM with local sheep produce hybrid lamb (male, female), mean birth weight was 3.1 kg, April age weight is 26.1 kilograms, respectively than native sheep increased 31.4% and 74.1%, the survival rate of lamb was 100%, increased by 5% than the Nubian black goat. According to experts, Aisha goat RAM with the local dairy goat, its production of improved 1 ~ 3 average annual generation of sheep milk 639 kilograms, an increase of more than 107% local dairy goat milk production, RAM fattening improve feed than local RAM (grass for meat, Pi Zhang) 57%. So, according to the economic type requirements for sheep breeding, plan selection and assortative mating, avoidance of inbreeding, to increase economic benefit.
