Embodiment 1

[0013] (1) Trial cows: choose strong, aggressive and easy-to-climb bulls from the hybrid bulls, ligature them, and then put them into the cow pens to mix with empty or weaned sow buffaloes. Each cow pen Put a bull, observe and record the cow's climbing performance and mucus discharge from the cow's genitals;

[0014] (2) Touch the rectum: extend from the anus to the rectum and touch the ovary. If you touch the ovary as big as a walnut, you can confirm that the ovary has matured and entered estrus;

[0015] (3) Treatment before mating: 12 hours before mating, perfuse the uterus with a mixture of penicillin, Houttuynia cordata, and 10% glucose at a ratio of 1:2:10;

[0016] (4) Promote ovulation: intramuscular injection of luteinizing hormone releasing hormone A before insemination 3 Two to promote ovulation;

[0017] (5) Deep insemination: insemination to one-third of the uterus, 2-3 times.

Abstract

The invention relates to a method for increasing a conception rate of artificial insemination of milk buffaloes. The method mainly comprises the following steps of cow heat testing; rectum touching; treating before mating; ovulation promoting; deep semen deposition. The method adopting the measures is different from a traditional mode of allowing oxen and cows to mate freely, at first, the ligation oxen test heat, the cows in heat are selected, then by touching ovaries deep in the rectums, whether the ovaries develop healthily and well or not is determined, the mature degree of the ovaries and the ovulation condition are mastered accurately, in combination with medicine treatment, the pregnancy rate and the ovulation number are increased, for deep semen deposition, the motion process of semens and ovums is shortened, and the pregnancy rate is increased; the conception rate during the first heat period of the milk buffaloes is about 25%, by the adoption of the method, the conception rate can be increased to 85%, and the effect is remarkable.

Description

technical field [0001] The invention relates to a method for improving the conception rate of milk buffalo artificial insemination, which belongs to the technical field of agricultural breeding, especially animal husbandry breeding. Background technique [0002] In the south, milk production only accounts for 15% of the country's total output, and a large amount of milk needs to be transferred from the north every year. The reason is that the south is not suitable for the development of dairy farming, so it is necessary to seek southern dairy farming technology or dairy breeds , and the milk buffalo is just a kind of dairy cow species suitable for breeding in the southern environment. Milk buffalo is a kind of buffalo mainly used for milk production, and the milk production can reach 2000-3000 kg / year. The buffalo milk produced by the milk buffalo is excellent, with a strong milk fragrance, pure white color, and no meal gas. It is a high-quality milk product with comprehens...
