The technology of pig rearing

To make pigs healthy, fast growth, input and output is proportional, we must create good conditions, specifically to do? Four good?

Pig technology

First, piglet lactation feeding management

(a) do a good job of piglet delivery.

(1) Remove the amniotic membrane and amniotic fluid

(2) Cut the umbilical cord

(3) Cut the canine teeth

(4) Cut the ear trumpet

(5) Tail clipping

(2) Supply colostrum and fix the teats in time

(3) Supplemental sources of iron. The most reliable method is to administer iron preparations intramuscularly to newborn piglets.

(D) good insulation. Insulation should be taken during lactation, maintained at 35 degrees in the first week, 31 degrees in the second week and 27 degrees in the third week. Insulation can be improved by using an incubator.

(e) Early supplementation. Seven days to start conditioning piglets to open the food to eat.

(F) Early weaning, do a good job before and after weaning. Weaned within a week to do four fixed: herd, enclosure, feeders, feed are maintained unchanged. The original nest fixed: do not immediately after weaning and nest, and nest will cause piglets fighting, increase the stress factor, so to keep the herd unchanged; enclosure fixed, the sows to drive away, piglets to stay in the original circle, so that it is familiar with the conditions of life; personnel fixed: feeding the sow continues to feed the weaned piglets; feed is fixed: weaned two weeks after the original piglets are still feeding material.

Second, piglet nursery period (weaning to 30 kg body weight) feeding management:

(a) Reasonable grouping, strengthen feeding management piglets weaned one week, according to the demolition of more than the demolition of less, demolition of the principle of strong and not demolition of the weak group. Gradually mixed into the full-price feed for piglets, let the piglets eat slowly increase.

(ii) control the environmental temperature weaning to weight 13 kg, to 27 degrees is the most appropriate, 13 kg to 23 kg, to 24 degrees is appropriate , 23 kg to 30 kg, to 21 degrees is appropriate.

(C) grasp the feeding density, to help piglets through the growth of dangerous period. Feeding density should not be too high, and the number of heads per pen should be no more than 20, which can improve the neatness of the piglets.

Third, the feeding management of the middle pig stage (30-60 kg body weight).

(a) Control the environmental temperature: 30-45 kg, 21 degrees is optimal; 45-60 kg, 18 degrees is appropriate.

(ii) grasp the feeding density: at least 0.9 square meters area per pig.

(3) The air convection in the pig house must be kept free, if the ventilation is poor, coupled with humidity, is very likely to cause respiratory diseases such as plasma membrane pneumonia, affecting the growth of pigs and feed conversion efficiency, especially the concentration of ammonia and hydrogen sulfide in the pig house, we must pay attention to the awareness and control at all times.

Fourth, the feeding management of large pig stage (60 kg weight to pen)

(a) Control the environmental temperature: when the weight of the meat pig reaches 60 kg or more, the optimal environmental temperature is 18 degrees.

(ii) Control the feeding density: at least 1 square meter per pig

(iii) Control the time of timely farrowing.

The main points of raising pigs

1. Raw and cooked feed. According to the characteristics of the type of feed to decide to take raw or cooked feed. The principle should be to reduce the loss of feed nutrients, improve utilization, and prevent poisoning and disease. Legume seeds, rapeseed cake, cottonseed cake, potatoes and sweet potatoes and other concentrates and juicy feeds should contain toxic substances. Cooked feeding to prevent poisoning. Swill contains various unknown substances and should be cooked and fed. Corn, wheat, sorghum and all kinds of green feed should be fed raw.

2. Thick feeding and thin feeding. Thin feeding because the feed contains more water, fast gastric emptying, small gastrointestinal stimulation, resulting in reduced secretion of digestive juices, reducing the digestion and absorption of feed. For this reason, the feed for pigs should be fed raw and dry and raw and wet. Fermented, silage, chopped and other processed feed to pinch together, scattered as appropriate. But after feeding to supply enough water.

3. Less and more meals. According to the type of pig, age, season and the nature of the feed to determine the number of meals. 7-day-old piglets entice unlimited number of meals; 20 days of age to weaning, you can feed more than 6 times a day; weaned piglets 4?5 times a day; sows and sows with piglets and late gestation sows 4 times a day; rack pigs, large meat pigs, boars 3 times a day. Hot summer days and nights are short and can be fed 1-2 times as appropriate; winter days and nights are short and long, then the first meal in the morning should be fed early, and once in the evening fed late, and once in the night.

4. feeding to? Four fixed? That is, fixed quality, fixed quantity, fixed time and fixed temperature. According to different age and use of pigs in accordance with the feeding standards to formulate the appropriate diet, the requirements of comprehensive and balanced nutrition, a complete range of varied collocation, palatability, quality and freshness. Timing is conducive to the formation of habits, regular secretion of digestive juices, promote digestion and absorption of substances. According to the nutritional situation of the pig and appetite, to determine the amount of daily feed for pigs, generally to feed after the trough is not leftover food, pigs do not lick the trough as appropriate. Spring, summer and fall are generally fed at room temperature, and in winter, hot water should be used to wither the feed and feed warm water as appropriate.

Pig farming is not only the traditional farming industry, but also the focus of livestock farming. Pork food is irreplaceable for other animal food, plus grain crops, vegetables and fruit cultivation requires a lot of agricultural fertilizer, biogas use must also raise pigs, so pig farming becomes more important.

Raising pigs is a systematic project, from the selection of seedlings, ingredients, management and disease prevention. To raise pigs well is not easy but also not impossible to do. To raise pigs well, raise the benefits to, must master the scientific knowledge of pig farming, and in practice, constantly summarize and improve. To this end, the following is the main point of feeding and fattening of the proven technology to help pig farmers to raise pigs, and then raise a good economic benefits.
