Technical Field

The invention relates to the technical field of mutton sheep breeding, in particular to a mutton sheep breeding method for five fetuses and ten lambs in three years.

Background

The mutton has high protein content, low fat and cholesterol content, contains a plurality of amino acids essential to human body, and has extremely high nutritive value; the mutton is warm in nature, can tonify middle-jiao and Qi, stimulate appetite and strengthen strength, nourish gallbladder and improve eyesight, and is beneficial to resisting cancer, treating chronic cough and asthma and improving the immunity of organisms after being eaten frequently. However, for social and historical reasons, for a long time, in the market consumption structure of meat products in China, the proportion of mutton is far lower than that of pork, according to the statistical bulletin of the national statistical bureau, the mutton yield in 2010 in China is 398 ten thousand t, the average number of people is only 2.97kg, the proportion of the total meat yield in China is only 5.02%, and the situation is exactly opposite to that in developed countries, so that the mutton yield in China is estimated to be seriously insufficient. With the continuous improvement of the income level of urban and rural residents in China, the consumption concept is gradually changed, mutton is more favored by consumers due to the advantages of greenness, safety, nutrition, health care and the like, and the consumption demand of mutton is continuously increased.

In recent years, the prices of grains and feeds are high, grain-consuming livestock and poultry pigs and chickens fight for grains with people all the year round, and meat products of the livestock and poultry pigs and the chickens greatly affect the feeding cost, the market price, the consumption demand, epidemic diseases and the like. In addition, because the breeding rate of the mutton sheep is relatively low, the breeding quantity cannot be greatly changed in a short period, the mutton supply is continuously tense, the mutton price can continuously run at a high price, and the rising space is large. Therefore, the market prospect of mutton sheep breeding is very huge.

However, the existing mutton sheep breeding technology in the prior art has the defects of extensive breeding management, low ewe lambing performance, low lamb survival rate, low weaning weight, low slaughtering rate and low breeding benefit.

Disclosure of Invention

Aiming at the problems, the invention provides a method for breeding mutton sheep with five fetuses and ten lambs in three years, which improves the production performance of breeding ewes, refines the feeding management, improves the lambing rate and scientifically matches the nutrition by hybridization breeding localization, meets the nutrition requirements of the sheep in different production periods respectively, ensures that the bred excellent production performance indexes can be stably inherited, copied and popularized, finally achieves the purposes of improving the breeding benefit and increasing the income of farmers.

In order to achieve the purpose, the technical scheme of the invention is as follows:

1. a mutton sheep breeding method for five fetuses and ten lambs in three years comprises the following steps:

s1, parent selection, namely selecting a postnotum goat as a parent female parent and a pure-breed Safosk goat as a parent male parent from the F1 generation double lambs of the Sahan sheep;

s2, before breeding, adding coarse feed powder and fine feed for the back ewes, increasing feed intake by improving palatability of the feed, and ensuring that the middle fat and upper fat of the back ewes are matched;

s3, first mating, wherein when postnotum lambs as parent females rut for the first time, the first mating is carried out according to the proportion of a pure breed Safosk sheep as parent parents to 15 postnotum lambs or less than 15 postnotum lambs;

s4, returning estrus and mating for the second time, when the postnotum vulgare is in the second estrus, performing second complementary mating according to the proportion of one pure species of Safosk sheep to 30 postnotum vulgare or less than 30 postnotum vulgare;

s5, adding high-protein feed to lactating postnatal ewes one week after lambing, and ensuring that feed in a trough of the lactating postnatal ewes remains when feeding at night, so that the postnatal ewes can conveniently eat;

s6, after production, separating mother and child for forced weaning of the lambs for two months, feeding the lactating ewes into a hybridization area for fattening feeding, preparing for the first hybridization in the next estrus, specially breeding the lambs, and ensuring that the lambs can eat feed in a sheep trough;

s7, when the lambs grow to the age of the week to the age of six, selecting and reserving the postnatal ewe as a parent female parent through the physical and morphological characteristics, and repeating the steps S1-S6 to improve the gene proportion of double lambs born by the postnatal ewe generation by generation. The lamb-bearing ewes are selected and retained among twins born between the ages of two weeks and six weeks through the physical and morphological characteristics, the gene proportion of twins born by basic ewes can be improved generation by generation, the proportion of twins born by the basic ewes reaches more than 85%, and the miscarriage rate of five fetuses in three years reaches more than 90%. Finally, the comprehensive index proportion of five fetuses and ten lambs in three years of the basic ewe group reaches more than 80 percent.

As an improvement of the technical scheme, the back ewes are sheared, repelled and epidemic-prevention before the early spring or the early autumn, the situation that the back ewes do not estrate due to too high or too low temperature is avoided, and the estrus of the back ewes is ensured by means of cooling in summer or heat preservation in winter

As an improvement to the above technical scheme, the former spring refers to a half month before the clearness, and the former autumn refers to a half month before the cold dew.

As an improvement on the above technical scheme, in step S4, after secondary breeding, the ewes are directly eliminated regardless of whether or not the ewes return estrus.

Compared with the prior art, the invention has the advantages and positive effects that:

the invention relates to a mutton sheep breeding method for five fetuses and ten lambs in three years. Through hybridization cultivation localization, the breeding ewe production performance is improved, fine feeding management is realized, the lambing rate is improved, scientific nutrition collocation is realized, the nutrition requirements of the ewes in different production periods are met respectively, stable heredity and copy popularization of the cultivated excellent production performance indexes are guaranteed, the cultivation benefit is improved, and the income of farmers is increased.
