(A) The use of old disabled cows
Cows, generally more than 10 years of age, regardless of the use of cattle, beef cattle, dairy cows, use value is reduced, can only use its meat to increase income. For such cattle, after a short period of fattening, the amount of meat produced can be increased. Specific methods: (1) Fully prepare for forage and feed. Before the start of fattening, the forage must be fully stocked and cut off midway to affect the fattening effect. During the finishing period, the “fattening fat†method is adopted, that is, in the proper temperature room, the room temperature is maintained at about 18 degrees Celsius to 22 degrees Celsius, which is lower than zero, which is not conducive to fattening. (2) The amount of feed, for each 1 kg of weight gain, needs 8 kg to 10 kg, and some green feed can be added, but not too much (the amount of feed also depends on the size of cattle and the reduction of small cattle). (3) The fattening period is 40 days to 60 days, over 150 days will affect the economic benefits. (4) The effect of fattening, reaching a daily gain of 1 kg to 1.5 kg.
(b) New methods for prolific mother-in-law
All biological reproduction is based on the sex of the female and the male, and the value of the cow is high as measured by the feeding value of the cow. According to foreign data reports, new methods can be adopted to produce more prolific cows. The methods are: (1) 20 to 30 minutes prior to artificial insemination, the first input of 5% arginine solution in the cervix of the cow can change the chromosome properties and increase the fertility rate of the mother's quail (no high-tech conditions Use); (2) add a large amount of calcium, magnesium feed, can increase the fetal and fetal pregnancy rate, such as vegetables, radish, large leafy vegetables and so on. Milk, eggs, carrots contain more calcium and magnesium. (3) High-tech Japan divides the fertilized egg into two parts under a microscope, half of which is used for sex identification, and the other half is used for transplantation. A half fertilized female egg is identified and transplanted into the uterus of a cow and placed on a fetus.
(III) When the fattening beef cattle have a high yield
From the growth and development laws and operations of beef cattle, the fattening method of “two high belts in the middle†was adopted. The calf grows faster before the age of one year, the growth in the second year is only 70% of the first year, and the third year is only 50% of the second year. In this way, from the consumption of feed, when it is 2 years old, it consumes 42% of the feed. , 3 years old consume more than 65% of feed. It can be seen from the perspective of consumption of feed and capital turnover, and the use of equipment, it is advantageous to keep young cattle. In turn, the age of slaughter is shortened, and there is less fattening of old age cattle, and the slaughter rate is over 25%. If breeding cows increase to 60%, the slaughter rate can reach more than 40%. It can be seen that shortening the breeding period of cattle not only can increase the slaughter rate, but also increase the proportion of cows and the number of calving herds, and the economic benefits of raising cattle are greatly improved.
