Embodiment 1

[0021] A kind of technology that the present invention proposes improves Laoshan milk goat breed ram reproductive performance, comprises the following steps:

[0022] S1, Artificial breeding: Select Laoshan dairy goat rams with normal reproductive performance proved by the mating test, and carry out feeding and management in the pen according to the conventional feeding and management technology of Laoshan dairy goat rams;

[0023] S2, long-day stimulation: in the two months before the summer solstice, that is, from April 22, the daily sunshine time is 13 hours. The artificial light source prolongs the light time for 80 minutes, and the light intensity is 200Lx. After 55 days, the sunshine time is 13.8 hours, and the artificial light is stopped. The reproductive physiological environment in the Laoshan dairy goat ram enters the longest light day of the summer solstice one month in advance. Stimulate;

[0024] S3, simulated short-day effect: after artificial light was stopped,...

Embodiment 2

[0028] A kind of technology that the present invention proposes improves Laoshan milk goat breed ram reproductive performance, comprises the following steps:

[0029] S1, Artificial breeding: Select Laoshan dairy goat rams with normal reproductive performance proved by the mating test, and carry out feeding and management in the pen according to the conventional feeding and management technology of Laoshan dairy goat rams;

[0030] S2, long-day stimulation: two months before the summer solstice, that is, from April 22, when the daily sunshine time is 13.3 hours, when the sun goes down every day, use it in the Laoshan dairy goat ram pen The artificial light source prolongs the light time for 90 minutes, and the light intensity is 225Lx. After 60 days, the sunshine time is 14 hours, and the artificial light is stopped. The reproductive physiological environment in the Laoshan dairy goat ram enters the longest light day of the summer solstice one month in advance. Stimulate;

Embodiment 3

[0035] A kind of technology that the present invention proposes improves Laoshan milk goat breed ram reproductive performance, comprises the following steps:

[0036] S1, Artificial breeding: Select Laoshan dairy goat rams with normal reproductive performance proved by the mating test, and carry out feeding and management in the pen according to the conventional feeding and management technology of Laoshan dairy goat rams;

[0037]S2, long-day stimulation: in the two months before the summer solstice, that is, from April 22, the daily sunshine time is 13.6 hours. The artificial light source prolongs the light time for 100 minutes, and the light intensity is 250Lx. After 65 days, the sunshine time is 14.2 hours, and the artificial light is stopped. The reproductive physiological environment in the Laoshan dairy goat ram enters the longest light day of the summer solstice one month earlier. Stimulate;

[0038] S3, simulated short-day effect: After stopping the artificial light,...

Abstract

The invention discloses a method improving laoshan mountain milk goat species ram reproductive performance; the method comprises the following steps: S1, artificial feeding: selecting laoshan mountain milk goat species rams tested by hybridization tests to have normal reproductive performance, and carrying for feeding management in a breeding house according to normal laoshan mountain milk goat species ram feeding management technology; S2, long-day stimulation: two months before summer solstice, i.e., from April 22nd, in which period the sunshine duration is 13-13.6 hours each day, after sunset each day, artificial light source is employed to prolong the lighting time for 80-100 minutes in the laoshan mountain milk goat species ram breeding house, the lighting intensity is 200-250Lx, the procedure continues for 55-65 days, and is stopped when the sunshine duration is 13.8-14.2 hours; S3, simulating short day effect; S4, hybridization, and semen collection. The novel method is simple in operation, low in cost, and single time ejaculation volume can be obviously increased; the method can obviously improve single time ejaculation sperm quantity and sperm mobility, thus obviously improving laoshan mountain milk goat species ram reproductive performance.

Description

technical field [0001] The invention relates to the technical field of animal reproduction, in particular to a technology for improving the reproductive performance of Laoshan dairy goat rams. Background technique [0002] Seasonal reproduction refers to the phenomenon that animals reproduce only in specific seasons in order to adapt to the living environment in the long-term evolution process. The reproductive behavior of most sheep and goat breeds from subtropical and temperate regions shows seasonal characteristics, changing with the annual photoperiod. Studies have shown that for seasonal breeding sheep, goats and other animals, the photoperiod signal is transmitted from the retina to the pineal gland through the nervous system, and is converted into a daily melatonin secretion cycle, with high secretion levels at night and low secretion levels during the day. The length of nocturnal melatonin secretion reflects the length of night and regulates hypothalamic gonadotropi...
