Breeding method for increasing farrowing rate of goats

Abstract

The invention discloses a breeding method for increasing the farrowing rate of goat, belonging to the technical field of goat breeding. The breeding method comprises the following steps: S1, site construction: a step of selecting a dry and ventilation grassland which faces south in the north, is convenient to drain water and is far away from residential areas and factories, establishing a ram captive breeding fence and a ewe captive breeding fence, and establishing an annular runway at the same time; S2, goat selection: a step of discovering and removing rams which do not meet the requirementsthrough semen quality inspection measures, and discovering and removing ewes which do not meet the requirements through ovum quality inspection measures; S3, breeding of the rams and the ewes in different pens: a step of breeding 5-7 rams in each ram captive fence, breeding 20 ewes in each ewe captive fence, and feeding a concentrated feed daily to enhance the constitution of the goats; S4, ram training; S5, taking of a seminal fluid; S6, Fecundin injection; S7, artificial insemination; and S8, management in a gestation period. The breeding method provided by the invention can effectively improve the farrowing rate of the goats, effectively improves economic benefits of farmers, and guarantees healthy lambs obtained through pregnancy.

Description

technical field [0001] The invention relates to the technical field of goat breeding, and more particularly, to a breeding method for improving goat calving rate. Background technique [0002] Meat, warm in nature, mutton can be divided into goat meat, sheep meat and wild mutton. In ancient times, mutton was called glutinous meat, glutinous meat and scorpion meat. It can not only keep out the wind and cold, but also nourish the body. Inflammation, deficiency-cold asthma, kidney deficiency and impotence, abdominal cold pain, physical deficiency and fear of cold, soreness and weakness of waist and knees, yellowish face and thin muscles, deficiency of both qi and blood, physical deficiency after illness or postpartum, etc. All deficiency symptoms have therapeutic and tonic effects and are most suitable for It is eaten in winter, so it is called a winter tonic and is very popular. China is the country with the most abundant goat breed resources in the world. There are two main w...

[0003] However, the litter rate of goats raised in captivity is low, mainly due to the high risk of miscarriage. There are two main factors for the occurrence of miscarriage in goats raised in captivity. The forage feed for goats is single in nutrition, and there is no high-quality and sufficient grass or green hay. The lambing season of goats is mostly winter and spring, which is in the middle of the green and yellow. The concentrate is mainly corn, and the protein feed is basically not fed. Vitamins , minerals, and trace elements are severely deficient, and goats are multiple-birth animals, which require a lot of nutrients during pregnancy, and miscarriages are prone to occur in the later stages of pregnancy. Although some ewes can conceive normally, the lambs produced are weak and difficult to walk. This kind of trace element is very easy to die, which reduces the reproduction rate. The application number "CN201910718995.8" discloses "a breeding method to increase the calving rate of goats, including the following steps: choose to face south, dry and ventilated, easy to drain, On the grassland far away from residential areas and factories, build pens for breeding, and the activity space of each sheep is 1.2-1.5m 2 ; Breed rams and ewes in separate pens, and the farm is equipped with an activity site. The rams and ewes are raised together for 2-3 hours every day, and the green feed and concentrated feed are fed daily; before the ewes enter the estrus period in autumn and winter, Select age 1-5 years old, strong and disease-free ewes and rams to house together, and the ratio of ewes to rams is 1:18-23; daily feeding green feed and nutritious feed; after the estrus period, put The ewes that were conceived in the coop were moved to an independent breeding pen for feeding, and the breeding temperature was kept at 26-28°C; they were fed green feed and enhanced feed on a daily basis”, but this patent has the following problems:

[0004] (1) In the selection of flocks, the patent selects ewes and rams that are strong and disease-free. As we all know, being strong does not mean that ewes and rams have the ability to reproduce, and rams and ewes will appear unable to reproduce. Phenomenon, how can this increase the litter rate, or even fail to give birth

[0005] (2) Breeding rams and ewes together for mating will lead to promiscuity, which will cause certain hidden dangers to the ewes and is not conducive to the health of the lambs

[0007] (4) The edible feed of the sheep in this patent is the basic feed, and the effect of improving the litter rate of goats is not obvious
