Embodiment

[0030] The experimental pasture of this embodiment is the first farming and animal husbandry breeding farm, and the specific test process is as follows:

[0031] 1. Materials and methods

[0032] 1.1 Test animals

[0033] A total of 140 Holstein cows with good body condition, an average lactation period of 150 days, and an average parity of 2.1 were selected as experimental animals. The test site is located in Yanqing Breeding Farm of Beijing Dairy Cow Center (longitude: 115.97E; latitude: 40.47N).

[0034] 1.2 Experimental diet and feeding management

[0035] Dairy cows are reared in a semi-tethered and semi-free manner, and feed freely. The daily feeding time is 07:00 am and 16:00 pm respectively. The milking time is 07:30 in the morning, 14:00 in the afternoon and 19:30 in the evening. The experimental rations were prepared according to the NRC (2001) Dairy Cattle Feeding Standard, and a fully mixed ration was prepared. The diet composition and nutrient levels are sho...

Abstract

The invention discloses a method for improving milk production performance and blood indexes of dairy cows and improving milk quality, and belongs to the technical field of dairy cow breeding. According to the method, a novel cowshed illumination system is mounted in the dairy cow breeding process, and the photoperiod is controlled to be 16h+ / -5% in illumination and 8h+ / -5% in darkness. The methodis simple and reasonable, the level of melatonin in dairy cow milk can be remarkably increased, the milk production quantity of dairy cows can be remarkably increased, the capacities of triglyceride,superoxide dismutase and total oxidation resistance in dairy cow serum are improved, and the level of malondialdehyde in the serum is reduced; and in addition, the method can also reduce the somaticcell number of dairy cow milk.

Description

technical field [0001] The invention relates to dairy cow breeding, in particular to a method for improving milk production performance and blood indicators of dairy cows and improving milk quality, and also relates to the application of a new type of lighting system for cowsheds, belonging to the technical field of dairy cow breeding. Background technique [0002] As an environmental factor closely related to living things in nature, light affects the physiological functions of almost all living things. It not only plays a direct role in the metabolic process and life activities of animals, but also plays a signal role, that is, periodic changes in light make animals According to the signal of light, it comprehensively regulates its physiological activities, affecting the growth, development, production and reproduction of animals. In the breeding and production of dairy cows, light, as an important part of the breeding environment, has become one of the indispensable condi...
