Problems solved by technology

Due to the individual differences of cashmere goats, it takes a long time for cashmere goats to comb cashmere. A group of cashmere goats usually lasts for about a month. At the same time, each cashmere goat has different cashmere removals in different parts, and some parts have better cashmere removal. It is easy to comb out, and some parts are not easy to comb out.

Embodiment 1

[0031] From January 30 to April 25, 2018, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 100 cashmere goats with similar age and growth status were selected, and 50 of them were routinely managed as the control group. Another 50 according to the artificial light increase program in the present invention carry out artificial light to increase the daily light time of cashmere goats, and carry out comparative experiments. Statistics, the statistical results are shown in Table 2 and Table 3.

[0035]

[0036] It can be seen from Table 2 and Table 3 that the concentration of melatonin (MT) in the blood of cashmere goats in the light group naturally decreased rapidly, and the levels of prolactin (PRL) and insulin-like growth factor-I (IGF-I) increased si...

Embodiment 2

[0045] On the basis of Example 1, from January 15 to April 15, 2019, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 90 cashmere goats with similar ages and growth status were selected and divided into three groups. There are 9 groups, and a comparative experiment is carried out. The experimental orthogonal design and the results are shown in Table 6 and Table 7.

[0050]The orthogonal design of the experiment is shown in Table 6. In this experiment, different lighting start times (January 15, January 30 and February 15) and different light intensities (200 Lux, 230 Lux and 250 Lux) were compared. , and the effects of different light durations (14h, 15h and 16h) on the amount of cashmere carding, carding strength, and time spent in carding, nine groups of experiments were designed through three-fact...

Embodiment 3

[0053] On the basis of Examples 1 and 2, from January 30 to April 6, 2020, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 40 goats with similar age and growth status were selected. The cashmere goats were divided into 4 groups, artificial light was added according to the lighting program, the colors of the LED lights were red, green, blue and white, and 10 cashmere goats in each group were used for comparative experiments. The experimental design and results are shown in Table 8. Show.

[0055]

[0056] It can be seen from Table 8 that different colors of LED lights have different effects on the cashmere production of cashmere goats. P P >0.05). However, there was no significant difference among the groups in carding strength and carding time ( P >0.05).

[0057] It can be seen from Example 3 that the amount of carding under the ...

Abstract

The invention discloses a method for synchronously shedding cashmere goats. From January 30th, use red or white LED lights for artificial lighting after sunset every day to increase the daily lighting time of cashmere goats: from January 30th to February 18th, increase the artificial lighting time to 5.5 hours a day; 2 From March 19th to March 13th, the daily artificial light duration is increased to 4.5 hours; from March 14th to April 4th, the daily artificial light duration is increased to 3.5 hours; The duration of artificial light is 2.5 hours; and the light intensity at the height of the eyes of the cashmere goats is 200 Lux. At the same time, each cashmere goat is supplemented with 100 mg of zinc methionine every day, so that the cashmere goats can achieve synchronous cashmere removal. The same state is achieved, and the herdsman saves time and effort when combing the cashmere, and the amount of cashmere is more; the time and labor cost of the herdsman's carding are reduced, the amount of cashmere combing is increased, and the income of the herdsmen is increased.

Description

technical field [0001] The invention relates to the technical field of animal husbandry production, in particular to a method for promoting cashmere goats to shed cashmere synchronously. Background technique [0002] Cashmere is a thin layer of fine wool that grows on the outer cortex of the cashmere goat and covers the root of the coarse hair of the cashmere goat. In 2018, the number of goats in my country was 135.7469 million, and the output of cashmere was 15437.76 tons. High-quality cashmere accounted for more than 80% of the global total, and it is a high-quality characteristic resource in my country. [0003] From the end of April to the beginning of June every year, herdsmen judge the time to comb the cashmere by checking the shedding of the cashmere around the ears and eye sockets, and comb the cashmere when the roots of the cashmere begin to loosen. Due to the individual differences of cashmere goats, it takes a long time for cashmere goats to comb cashmere. A grou...
