High efficiency of feed safety management in large-scale pig raising provinces

In the direct cost of pig production, feed accounts for about 70%. In the situation where feed prices continue to climb, it becomes increasingly important to be able to meet the nutritional requirements of the organism while saving feed and increasing income. Here are a few simple ways to increase the size of your pigs:

1. Choosing piglets on a large scale Pigs must choose to raise “Sanyuan” crossbred piglets. It is best to use Changbai and Yorkshire pigs with long waist, wide chest, short mouth, full hips, strong limbs, and food for grab food. , only about 160 days to reach 90 to 100 kg, can shorten the fattening period of 20 to 50 days.

Second, the divided-circled piglets should be kept in separate circles after 60 days of age, with 2 to 3 pigs per circle, so as to avoid chasing energy in outdoor pursuits.

3. Castrated 30-day-old boars and 40-day-old gilts in a timely manner were castrated and weighed about 15% more than the customary 60-day-old grazing. The wounds healed quickly, shortening the finishing period by about 20 days, and saving feed. About 20%.

Fourth, timely insecticide stomach piglets drive the first time at 60 days, the first insect, and then once every 2 to 3 months to drive the insects, according to pigs per kilogram of body weight with anti-creeping or insect repellent net 15 to 20 mg, a mixed feed Take away the parasites from your body. If there is swine fever, 10 g of salt, 10 ml of kerosene, and 20 ml of warm water can be mixed and applied to the surface of the pig to kill insects. At the same time as deworming, 1 kg of quicklime was dissolved in 5 kg of water for each pig. The above supernatant was fed and fed twice a day. Two to three days of gastric lavage was used to remove various insect pests. One week later, pigs were given a piece of rhubarb soda per kilogram of body weight (maximum no more than 15 tablets), and the stomach was fed in three batches. In this way, each pig can increase the weight of 10 to 15 kilograms and shorten the 25 to 40 days of fattening period.

V. Scientific Feeding According to the growth and development laws of the pigs growing slowly in the early stage, fast in the middle stage, and slowing in the later stage, in order to obtain higher feed remuneration, the straight-fattening feeding method should be adopted to shorten the feeding period and save the feed. At the same time, it is necessary to implement fine, green, and coarse feed mixes, and to implement dry feed for raw feeding; in the number of feeds, two feeds should be taken daily to reduce the consumption of energy and feed due to multiple feedings to stimulate pig movements. Loss of throwing, reducing feed utilization.

Sixth, stage breeding sows empty phase and the first 80 days of pregnancy can be fully based on green feed, high quality rough feed and bad dregs feed, with only about 1 kg of fine material a day. One month before labor, feed 2 to 3 kg of concentrate every day. In this way, the normal development of the fetus is guaranteed, and the sow can save 60-90 kg of concentrate feed for each pregnancy.

VII. Timely mating The early weaning of piglets 60 days of age to 40 to 45 days, this can promote the early estrous sows, early mating, shorten the empty period, and relatively save feed.

VIII. Strictly Preventing Epidemic Diseases In spring and autumn each year, “three-joint seedlings” are injected on time to pigs, which can effectively control the three major diseases of swine fever, swine erysipelas, and swine plague, reduce mortality, and relatively reduce material consumption.

IX. When pigs weighing 20 to 90 kg in a timely manner, the daily weight gain rises linearly. After 100 kg, the growth rate is slow, and the daily weight gain gradually decreases. Therefore, it is better to raise the slaughter to about 90 kg.

Alternative Tea

Substitute tea refers to the use of edible plant leaves, flowers, fruits (fruit), roots, etc., using the way of drinking tea (by brewing, boiling, etc.) is a kind of products commonly known.
Substitute tea is divided into leaf, flower, fruit and rhizome; The way of drinking the same as tea is generally composed of one or more items in the two categories of "medicine and food homology" and "can be used for health care" in the food classification stipulated by the Ministry of Health. Tea products made from the roots, stems, leaves or fruits of these plants.
