Specific wavelength light control device and control method for improving the efficiency of simultaneous estrus in rabbits, cats and minks

Abstract

The invention discloses a specific wavelength light control device capable of improving synchronous estrus efficiency of fur-bearing animals like rabbits, cats and martens and a control method thereof. The device comprises a specific wavelength light source and a light source controller, the light source controller comprises an intelligent dynamic time relay, a light intensity sensor and a PLC(programmable logic controller) processor, the specific wavelength light source is mounted above the middle of a shed for the fur-bearing animals like the rabbits, the cats and the martens, to-be-mated cages are arranged on two sides in the shed for the fur-bearing animals like the rabbits, the cats and the martens, and the light source controller is arranged on one side of a wall; the control device further comprises ear tag radio frequency recognizers, one ear tag radio frequency recognizer is mounted on one ear of each fur-bearing animal, and signals of the ear tag radio frequency recognizers are transmitted to the PLC processor. By the specific wavelength light control device and the control method, a specific wavelength light source can be emitted dynamically in a needed time period, light-sensitive characteristics of the fur-bearing animals like the rabbits, the cats and the martens can be utilized to induce synchronous estrus of the fur-bearing animals like the rabbits, the cats and the martens, tolerant effect on the fur-bearing animals like the rabbits, the cats and the martens by using exogenous hormones is eliminated, and labor input and production cost are lowered remarkably.

Description

technical field [0001] The invention relates to the technical field of fur animal (rabbit, cat, mink) reproduction, in particular to a specific wavelength light control device and a control method for improving the estrous synchronous efficiency of fur animals (rabbit, cat, mink). Background technique [0002] Light is one of the main environmental factors affecting the reproductive activities of livestock and poultry. In the poultry industry, artificial control of light cycle and intensity is widely used to promote and improve its production performance. Practice has proved that the wavelength of light, photoperiod and light time can all play a certain role in the growth and development of poultry, and then affect their body maturity, sexual maturity, production performance, reproductive performance and product quality. In poultry, as early as 1983, Foss and White reported that red light can increase the egg production of laying hens, while short-wavelength light has littl...

AI Technical Summary

Problems solved by technology

[0004] How to use the reproductive rhythm mechanism of light-sensitive animals to realize the periodic breeding mode without artificial hormones, the key lies in how to control the secretion of GnRH in the hypothalamus to cause the rhythmic release of FSH from the pituitary gland and induce the simultaneous estrus of female animals. Relevant scholars at home and abroad have focused on this hot spot. Relevant research work has been carried out, but due to technical limitations, specific wavelengths of light and supporting control devices have not been screened to achieve precise control of fur animals (rabbits, minks) at the same time in estrus
