Yak early feeding is good
The early feed of beef calves is to supplement calves with mixed concentrates at the age of 2 to 3 months after the calf's birth to meet the nutritional needs of its growth and development. Meat yaks have the advantages of rapid growth, good meat production, and good meat quality. With the increase of yak's month age and the decrease of cow's lactation, breast milk can't gradually meet the nutrition needed for its growth and development. If feeding is not timely, It will cause the growth of yaks to be hindered, and it will also directly affect their growth and development in adulthood. Therefore, the use of early feed technology can make up for the lack of breast milk nutrition, increase the growth rate of calves, and thus increase the economic benefits of raising cattle.
1. Benefits of early feeding According to the trial of Chenhu cattle farm in Shanting District, Zaozhuang City, Shandong Province, early feed technology can increase the weaning weight and feed reward of yaks, and can also promote the early development of calf's foregut. In this field, a mixed breed of yak from Limousin began to feed at 3 months of age, and it was weighed at 180-220kg at the age of 6 months of weaning. The weight of non-feeding hybrids was only 156kg, an increase of 15% to 41%. The feed weight of calf during feeding is 1:1. If the effect of breast milk on weight gain is ruled out, the yak consumes only 2.8-3.2 kg of mixed concentrate per 1 kg of weight gain and the feed reward is significant.
Since yak breast milk is directly digested and absorbed when the breast milk is directly introduced into the stomach, the forefoot cannot be stimulated by fine material and coarse material, and the normal rumen microflora cannot be established, which will also affect its own development. After an early feeding calf is fattened after weaning, the annual weight can reach 418kg, which can be slaughtered in the current year. The non-feeding weaned fattening can reach the slaughter and weight at least 14 to 15 months of age.
2. Method of feeding early yak early feed should start from 2 to 3 months old, feed 1 time a day, in the afternoon or at dusk. Mix the mixture with water in a ratio of 1:2.5 into a wet thick material, depending on how much milk is fed and the weight of the calf. In general, when feeding is started at the age of 2 months, 0.2 to 0.3 kg of mixed concentrate is fed daily. As the calf's age increases and its weight gains, the amount of feed increases gradually. By the age of 6 months, the amount of feed will reach 1.5kg. In addition, yak should be supplied with soft, good quality green fodder for free feeding. The reference formula of the mixed concentrate is (%): corn flour 45, bran 20, bean cake 8, cottonseed cake 5, additives (trace elements, vitamins) 3, corn stover powder 17.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
