Description
Technical Field
The invention relates to the technical field of animal breeding, in particular to a method for breeding a small-tailed sheep hybrid variety for meat by the hybridization of Dorper sheep and small-tailed Han sheep.
Background
Dorper sheep is produced in south Africa, bred by crossing horned Dorset sheep and Persian black head sheep, and is a famous mutton sheep variety in the world. The Dorper sheep is famous for high growth speed of lambs, heavy weaning body, high dressing percentage and high meat yield. Therefore, it is also known as the "king of mutton sheep". Although the body type is moderate, the body is full.
The small-tailed han sheep is a sheep variety which can be used for both meat and fur, and has the characteristics of early maturity, quick growth and development in early stage, high physique, good meat quality, estrus in four seasons, strong fecundity, stable heredity and the like. Is known as Chinese 'national treasure', world 'super sheep' and 'high-leg sheep' by nationally positioning famous livestock fine breeds. But the first two months are dominated by bone growth.
Therefore, a method for breeding small-tailed hybrid meat by hybridization by using a high-yield Dorper sheep as a male parent and a small-tailed Han sheep as a female parent becomes a problem to be solved urgently.
Disclosure of Invention
The invention aims to solve the technical problems that although the meat yield of the Dorper sheep is high, the body type of the Dorper sheep is moderate; although the small-tailed han sheep matures early, grows and develops fast in the early stage, is high in physique, good in meat quality, capable of oestrus in four seasons, strong in fertility and stable in heredity, the first two months mainly take skeleton growth as a main factor.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a method for breeding a small-tailed sheep hybrid variety by the hybridization of Dorper sheep and small-tailed Han sheep, which comprises the following steps:
step 1: and (3) cross breeding: a. identifying and evaluating the Dorper sheep rams and the small-tailed Han sheep ewes, selecting excellent Dorper sheep as male parents and excellent small-tailed Han sheep as female parents, so that the Dorper sheep rams form a ram group and the small-tailed Han sheep ewes form a ewe group;
b. providing forage grass with excellent grass quality for breeding flocks of sheep, and allowing the flocks of sheep to freely drink water;
c. the ram group formed by the Dorper sheep rams is trained, and the sperm activity is improved;
d. carrying out first hybridization breeding on the male Dorper sheep in estrus and the female sheep of small-tailed Han sheep in ovulatory period, carrying out intraspecific breeding to obtain F2 generation, carrying out second hybridization breeding on the male sheep and the female sheep of F1 generation, and carrying out intraspecific breeding to obtain an F3 generation small-tailed sheep hybrid variety;
step 2, breeding and breeding: breeding, disease prevention and fine variety screening are carried out on the F3 generation small tailed sheep hybrid variety, and a variety with good heredity is selected for propagation expansion.
Furthermore, ovulation is carried out in 30-40 hours after the ewes of the small-tailed Han sheep are estrated, the time for inseminating the discharged ova is about 12 hours, and at the moment, mating is most prone to conception; in order to ensure the conception rate, repeated mating is needed, insemination is carried out within 10-17 hours after the heat of the small-tailed han sheep is detected, and the interval between two mating is 9-15 hours.
Compared with the prior art, the invention has the advantages that: the invention adopts the dolapol sheep with high meat yield as the male parent, and the small tailed han sheep with early maturity, fast growth and development in early stage, high physique, good meat quality, four seasons estrus, strong fecundity and stable heredity as the female parent for hybridization, so that the offspring of the two can not only achieve the advantage complementation, but also can generate higher economic benefit; the invention has reasonable design and is worth popularizing.
Detailed Description
The method for cross breeding meat small-tailed sheep hybrid by Dorper sheep and small-tailed Han sheep is further explained in detail below.
A method for breeding small-tailed sheep hybrid for meat by the hybridization of Dorper sheep and small-tailed Han sheep, which comprises the following steps:
step 1: and (3) cross breeding: a. identifying and evaluating the Dorper sheep rams and the small-tailed Han sheep ewes, selecting excellent Dorper sheep as male parents and excellent small-tailed Han sheep as female parents, so that the Dorper sheep rams form a ram group and the small-tailed Han sheep ewes form a ewe group;
b. providing forage grass with excellent grass quality for breeding flocks of sheep, and allowing the flocks of sheep to freely drink water;
c. the ram group formed by the Dorper sheep rams is trained, and the sperm activity is improved;
d. carrying out first hybridization breeding on the male Dorper sheep in estrus and the female sheep of small-tailed Han sheep in ovulatory period, carrying out intraspecific breeding to obtain F2 generation, carrying out second hybridization breeding on the male sheep and the female sheep of F1 generation, and carrying out intraspecific breeding to obtain an F3 generation small-tailed sheep hybrid variety;
step 2, breeding and breeding: breeding, disease prevention and fine variety screening are carried out on the F3 generation small tailed sheep hybrid variety, and a variety with good heredity is selected for propagation expansion.
Ovulation is carried out in 30-40 hours after the ewes of the small-tailed Han sheep estruse, the time for inseminating the discharged ova is about 12 hours, and at the moment, mating is most prone to conception; in order to ensure the conception rate, repeated mating is needed, insemination is carried out within 10-17 hours after the heat of the small-tailed han sheep is detected, and the interval between two mating is 9-15 hours.
