Improve the benefit of raising pigs from two aspects of selection and feeding

Choose to raise lean hybrid pigs

Lean hybrid pigs grow fast, use less feed, have strong resistance to disease, have good reproductive performance, and the average litter size of lean pigs is 3 ~ 4 heads more than that of fat pigs. The conversion efficiency of feed into fat is 4:1, while the conversion efficiency of lean meat is 1.2515. In other words, 3.2kg lean meat can be produced by producing 1kg fat feed. The lean meat rate of excellent hybrid pigs is more than 58%, the daily gain is increased by 13% to 53%, the lean meat rate is increased by 15% to 20%, the lean meat rate is increased by about 11 kg, the feed is saved by more than 15 kg, and the income is increased by 30 to 60 yuan. In addition, the animal protein content of lean meat is more than 20%, which can be well absorbed by the human body, has good palatability and has a good market. The price of fat meat in foreign countries is 1 jump 20 of that of lean meat, and that of our country is basically 1 beat 10 times 1 hand 7, which shows that the economic value of lean meat is higher.

The choice of pig fry is very important. First of all, it is necessary to determine the variety, because the pork variety is different, its growth rate is also different. Native pigs grow relatively slowly and take longer to grow. Crossbred pigs grow faster and have a short breeding time. Studies have shown that the growth rate of binary hybrid pigs is 10%-20% faster than that of purebred pigs, and the growth rate of ternary hybrid pigs is about 15% higher than that of binary hybrid pigs. In terms of body shape, excellent young pigs have long waist, wide front chest, short mouth, plump buttocks, stout limbs and normal proportion. The appetite of excellent pig seedlings is proportional to the rate of weight gain. When breeding, it is necessary to choose good appetite, active tail, no thin dung, strong body and no cough. Generally speaking, pigs with short and thick tails grow faster, so they use less feed. The young pigs in the same litter live in harmony with each other, it is easy to be raised in captivity, and it is not easy to bite.

Feed pigs with raw meal

From a practical point of view, feeding raw feed to pigs has many advantages. Raw meal without cooking, in which the rich nutrients are retained completely, nutrition is more comprehensive, feed use efficiency is higher; there are many kinds of raw meal, with good palatability, meat pigs have a better appetite, so they grow rapidly. Some data show that the average daily gain of each pig fed with raw meal is 313 grams, and the average daily gain of each pig fed with clinker is 266 grams, and the daily gain of pigs fed with raw meal is 35% higher than that fed with clinker. From the point of view of material saving, the feed consumption of pigs fed with raw meal is lower than that of clinker by 11% to 34% for every 1 kg gross weight gain; when the piglets grow to the body weight, the fuel cost can be saved by 13 yuan to 17 yuan; and the labor can be saved by 20 to 40 when raw meal is fed to pigs without cooking or boiling water. Pigs eat more and grow faster, which shortens the fattening period, speeds up the turnover rate of pigs, and relatively improves the utilization rate of the enclosure. Pigs are fed scientifically, grow fast and physically strong, and enhance disease resistance. The average litter weight of piglets fed with raw meal increased by 2.4, the birth rate increased by 30%, the survival rate increased by 12%, the average weaning weight increased by 2.5 kg, and the daily gain increased by 20%. The slaughtering rate of pigs fed with raw feed was 72%, while that of pigs fed with clinker was 70%, which increased the slaughtering rate. The fat thickness of raw feed is 2.7 cm, and that of clinker is 2.9 cm. The lean meat percentage is increased by more than 3%, thus increasing the lean meat rate. The method of feeding raw meal to pigs is simple, easy to learn and easy to popularize.
