The invention provides a technique for breeding high-quality sheep through a three-breed crossing method, and belongs to the field of livestock breeding. By taking small tailed han sheep (named 'han' for short) with the higher multiple pregnancy rate as a female parent, fully utilizing poll dorset (named 'tao' for short) and bald suffolk (named 'sa' for short) which are good in mutton quality and rapid to grow as male parents and adopting the important techniques such as first generation target matching crossing, second generation interlacing crossing, third generation and fourth generation backcrossing, high generation mass mating, type stable selecting and series variety selecting of multi-type three-breed crossing, three-breed crossed breeding sheep of multiple types of the 'han, tao, sa' sheep are bred, the three-breed crossed breeding sheep is high in multiple pregnancy rate, good in mutton quality, rapid to grow and wide in application and integrates the advantages of the three types of sheep, and multiple types of breeding sheep such as 'tao-similar' sheep, 'sa-similar' sheep and 'han-similar' sheep which are similar to the different types and have the mutton-wool dual purposes are generated.

The invention relates to the technical field of animal molecular markers and applications, in particular to a molecular marker capable of simultaneously indicating and identifying the spinning count and the curvature property of sheep wool and an application of molecular marker in simultaneously indicating and identifying the spinning count and the curvature property of the wool of Chinese Merinosheep. The molecular marker capable of simultaneously indicating and identifying the spinning count and the curvature property of sheep wool is located at the 23th exon of No.21 chromosome of the FAT3gene. The invention firstly discloses an rs601824181 SNP site which is taken as the molecular marker capable of simultaneously indicating and identifying the spinning count and the curvature propertyof sheep wool. The rs601824181 SNP site is applied as a selection to simultaneously indicate and identify the spinning count and the curvature property of the wool of Chinese Merino sheep, early selection of varieties of breeding sheep with excellent spinning count and curvature property of sheep wool can be performed, and sheep can be selected and remained after being born.

The invention relates to a method for resource utilization of agricultural waste feed, belonging to the technical field of animal husbandry. The method is as follows: primarily smashing agricultural waste rice straw, water hyacinth growing in non-industrial polluted river channels and ponds, and a by-product vinegar waste in vinegar processing factories; mixing, compacting and sealing according to a specific ratio; and carrying out anaerobic fermentation for 30 days to obtain an ensiling processed-similar fermented feed for feeding sheep. In the method, foreign additives are not needed, fermentation can be carried out under natural conditions, an above average production level when being used for the fattening of growing sheep can be reached, and the adopted processing raw materials are all agricultural wastes, thus providing a new effective way for resource utilization of agricultural waste.

The invention discloses a staged feeding management method of black goats. Feeding management means can be adopted according to different growth and development stages. The method specifically comprises the following steps: black goats comprise suckling stage lambs, lactation stage ewes, weaning stage lambs, adolescence stage adult goats and breeding goats according to development stages, the suckling stage lambs and the lactation stage ewes are stocked in corresponding farms according to day ages, and the weaning stage lambs, the adolescence stage adult goats and the breeding goats are stocked in different isolated open pastures or different isolated goat pens; the suckling stage lambs are fed respectively according to day ages, suckling stage lambs 20 days after birth are lactated by ewes and assisted by lamb milk powder or fresh milk, and fresh grass feeding is trained later; goats at different stages are fed respectively with different proportions and types of forage, and accordingly, manual grass planting for corresponding forage is performed in open pastures. The black goats at different stages are fed in a staged manner, so that the survival rate of lambs is high, and muttonis compact.

The invention provides a method for breeding an improved mutton sheep strain, which includes the steps: firstly, using a plurality of rams as strain ancestors to mate with 30-50 ewes respectively so as to establish a plurality of families; secondly, performing beneficial-trait within-family selection to more than four generations of the families established in the step 1; thirdly, subjecting the families selected in the step 2 to family hybridization; fourthly, using hybrids obtained in the step 3 and family non-hybrids to establish a strain breeding core group, and grouping other individuals as a production group; fifthly, subjecting the core group established in the step 4 to beneficial trait selection, opening the core group, allowing selected qualified individuals in the production group to enter the core group, introducing 'foreign blood' timely to avoid inbreeding depression; and sixthly, obtaining the mutton sheep strain with beneficial traits adaptable to local environment by multi-generational breeding. By using the method to breed the improved mutton sheep strain, dependence on foreign varieties is lessened, and the current situation of 'all introduction and propagation and no breeding' in the field of breeding sheep introduction in China is changed.
