Reducing the cost of hog raising
In order to obtain the ideal breeding efficiency, specialized breeding pigs of cross-breeding pigs must choose cross-breeding pigs that are resistant to roughage, early maturation, easy feeding, early slaughter, and high lean meat percentage. In order to meet the market demand, it is best to choose Duchang, Du Da binary cross or Du Dachang, Du Chang Da three-way hybrid lean meat pigs.
According to the growth characteristics of piglet long bone, middle pig long skin, large pig long flesh, and fat pig long loquat, when the pigs begin to accumulate fat at 5 to 6 months of age, the compound feed should be based on energy concentrates. Such as corn, barley, sorghum or bran feed; When the fat began to accumulate under the skin, it was changed to feed with beans, wheat, cakes and blood meal, fish meal, bone meal and vitamins, minerals, compound feed additives. Mixed feed. Adopt the method of dry feeding raw materials to increase feed utilization and increase the growth of lean meat nutrients.
Improving the environment of the pig house The environment of the pig house is also one of the factors determining the growth rate of the hog. The suitable temperature for pig growth is 15°C~25°C, relative humidity is 55%~60%, the temperature and humidity are too high, the heat dissipation of pig body is hindered, and it is easy to cause heat stroke and metabolic disorders; if the temperature is too low, the pig body will dissipate more heat and consume feed. More, increase feeding costs. For this reason, when the summer temperature exceeds 28°C, use cold water to spray the sheds at noon, or use a pergola to shading. In winter, be sure to keep cold and heat-insulating. In the circle, you can lay 10~15 cm thick hay, and use warm sheds to raise pigs. Effectively improve feed utilization.
Supplying sufficient water The water in pigs accounts for 1/3 to 1/2 of the body's water content. It plays an important role in regulating body temperature, running nutrients, digestion and absorption, and excretion of wastes. Therefore, sufficient clean drinking water must be provided to ensure the healthy growth of pigs and maximize their growth potential.
Changing Hanging Frames for Finishing and Finishing Traditionally for Hanging Lines The traditional hanging frame for fattening is to control nutrient levels in the early stage, and later to increase the energy feed for fattening. This method has a single feed, nutrition is not comprehensive, can not meet the growth needs of pigs, pig growth is slow, long feeding cycle, slaughter rate is low. If the pig is weaned until slaughter, the straight-line fattening has been carried out using the full-price compound feed, which can effectively shorten the fattening period and increase the slaughter rate.
The regularity of growth and development of hogs at the right time is that the weight gain in the early stage is slow, the weight gain in the middle period is fast, and the weight gain in the later stage is slower. When the weight of the pig exceeds 100 kg, the daily weight gain begins to decline, and the larger the body weight, the lower the daily weight gain, and the more the feed is consumed. The weight of pig slaughter is too small, although the feed is saved, the slaughter rate is low and the meat quality is not good. In addition to slaughtered pigs weighing approximately 75 kg in early maturing breeds, cross-breeding improved pigs more than 35 to 45 days of age and weighing 10 to 15 kg. After weaning, straight-line fattening is performed, full-priced compound feed is used intensively, and large amounts of green roughage are added to feed. Appropriate amount of additives, do a good job deworming, stomach, epidemic prevention, summer and autumn pay attention to heatstroke, winter and spring to implement warm sheds, pigs 7 to 8 months of age, weighing 110 kg when the most economical slaughter.
