Yak fattening calves before 3 months of age have a faster growth rate and a large amount of protein. In the diet, protein feed can account for 20%. At the same time, because the rumen development is very imperfect, the body can not synthesize some essential amino acids, so it should be fed with different protein feed. When the yak is 6-12 months old and weighs 150-200 kg, the protein feed in the diet can be reduced to about 15%. Later, as the weight of the calf increases, the amount of protein feed in the diet can be gradually reduced to 12%. Shelf cattle fattening in the house for fattening, shelf weight of about 300 kg of shelf cattle, protein feed in the proportion of its diet can account for 10% -13%. By the end of fattening, the protein feed can account for 10% of the diet. Older cattle fattening is fattened by older cattle. The protein feed in the diet needs only 10%, but it must be fed with energy feed such as corn, sorghum and sweet potato. If fattening high-grade beef cattle is to be fattened with high-quality cattle to produce high-grade beef, the content of protein feed in the diet should be increased by 2%-3% compared with ordinary beef fattening.
Light weight indoor LED Grow Light is a kind of lighting equipment specially designed for indoor growing plants. Its lightweight design makes it easy to install and hang, and is suitable for a variety of growing environments, including homes, offices and greenhouses.
Light weight plant Led Grow Lights usually use LED light sources because leds have low energy consumption, high brightness and long life. These lamps often have adjustable brightness and spectrum, which can provide the appropriate light according to the growth needs of the plant.
The design of the light weight plant lamp also takes into account the photosynthesis needs of the plant. They usually have a suitable spectral combination, including blue, red and white light, to meet the light needs of the plant at different stages of growth. Blue light can promote leaf growth and health, red light can promote flower bud and fruit development, and white light can provide a more natural light environment.
In addition, light weight full spectrum Led Grow Lights also have the characteristics of energy saving and environmental protection. The energy consumption of LED light sources is relatively low, which can save energy costs. At the same time, they do not contain toxic substances such as mercury and have no pollution to the environment.
