Various types of pigs and feeding techniques

1, piglets of the nurturing technology (1) eat enough to ensure that breast-suckling piglets: Postnatal their sole source of nutrition is breast milk, breast milk only eat enough to ensure the nutritional needs of its growth, with the age and weight gain, need to increase the amount of breast milk, but milk secretion reached a peak of 21 to 25 days, then gradually reduced, so, in order to ensure normal growth, breast milk alone can not meet the nutritional needs of pigs, which requires timely fed to the pigs; (2 ) pay close attention to feeding: feeding pigs to be early, the implementation of early feeding on the one hand you can exercise piglet digestive function, nutrient deficiencies on the other hand can add breast milk, usually from 6 to 7 days after birth, began to lure pigs eat the material, After 2 weeks of training, to 3 weeks of age to be a certain amount of feed intake; to pigs fed feed including feed concentrates,[link widoczny dla zalogowanych], green fodder, minerals and vitamins servo feed material. In the feeding process, the concentrate feed should be noted that the pellets to powder, from less to more gradual. Succulent green feed should be broken or beating mixing with the concentrate mix, mineral feed to break, mix well, special attention iron, copper and other trace elements added. 2, pigs weaned piglets and feeding techniques required to supply nutrition and feed into the breast milk obtained only from the diet, changes in these conditions, piglets to a stress stimulus. Pigs tend to be loss of appetite,[link widoczny dla zalogowanych], weakened digestion, so the injection is better palatability of feed, nutrient balance, easy to digest. Diet should contain the growth of bones and muscles need energy, crude protein, minerals? And vitamins. Piglets should concentrate mainly material and type of diversification. Energy feed corn, barley,[link widoczny dla zalogowanych], sorghum, soybean and bean protein diet is a good feed. Early weaning, feeding amount should be controlled to some extent control the rate of 80% is appropriate. Then free to feed, feed form the powder, granular materials as well. 3, growing pigs and feeding techniques (1) According to the fast growing pigs, nutritional needs and rationally formulated diets. (2) scientifically prepared diet: To improve palatability, improve the efficiency of feed Lean, often taken for green chopped forage fed beating students in order to reduce volume, reduce waste, for the concentrate, in addition to crushing, but also for with the modulation into a variety of forms, such as pellets, dry powder, wet spices and thinner. Currently in production, often in both powder and wet spices. (3) feeding technique: in pig breeding in? Often used ad libitum feeding and a limited two types: free pig feed slot is placed in sufficient quantities for the full price of feed, feed the pigs any, free access to water. The limited feeding is the conscious control of Feeding Amount, the general control ad libitum or 80% of adding indigestible dietary fiber feed. To reduce the energy concentration. Control energy intake of protein. For small pigs growing season, according to its use, flexible use of feeding method for feeding as a test animal can be limited in order to reduce weight gain, such as roast suckling pig, you can use free feed, to increase weight gain speed. As the number of feeding days feed 2 to 3 times better. 4, pregnant sows and feeding techniques (1) the preparation of diet, you must always has two key features of the period, early period of pregnancy, diet structure is mainly green fodder, concentrate ratio does not exceed 40%, can be used with large volume high-quality green forage, late pregnancy, the diet of concentrate feed can be 60 to 70%, less green fodder fed to reduce the volume, the other, non-feeding mildew, rot, frozen, and there is a strong irritant harmful to feed. (2) to strictly control the amount fed, the implementation of limited feeding, feeding about 1.5 kg per day, should not feed too fat, otherwise it will reduce the reproductive performance and cause dystocia. In production to control weight gain to control the Feeding Amount, for the small pigs to gain 15 kg child is appropriate. Recommended system for pregnant sows were fed: 1 ~ 80 days of pregnancy from 1.0 to 1.3 kg feed ten full price as possible to meet the green fodder 110 days 81 ~ 1.3 ~ 1.5 kg feed ten full price amount of green feed delivery 110 ~ 1.0 ~ 1.2 kg full price Ten small amount of green feed material 5, lactating sows and feeding techniques (1) Feeding: daily from the milk of lactating sows secrete large quantities of nutrients for the needs of piglets, nutritional burden is very heavy. Therefore, weight loss of sows during lactation, especially sows with high milk yield. In order to ensure normal lactation and minimize the weight reduction, and the next normal breeding breeding sows on lactation should be implemented to strengthen the whole feeding period. (2) prepared by the standard diet, the diet should be based on the structure-based energy ~ protein feed, breast-feeding accounted for 85 ~ 90% of the early, mid-80 ~ 85 75 ~ 80% of late lactation, attention to fine ~ the proportion of roughage. Proportion of pre-concentrate of nutrients 75 to 80%, then gradually increase the green roughage diet should be diversified, and relatively stable to the same or less becomes applicable. (3) feeding technology. a, farrowing, the body, extreme fatigue, reduced stamina, digestion function has not yet returned to normal, should be fed with digestible feed, such as the Valley real powder, small Maifu etc., less the amount of feeding, after 3 to 4 days transition to a normal Feeding Amount. b, at the peak of lactation, feeding should be strengthened to ensure that when you meet or exceed nutrient requirements of lactation in order to maximize the power of the sow's milk. c, to improve feed intake, feeding frequency should be increased to as much as possible the principle of eat, feed form, and should be suitable wet spices and thick materials. Good feeding system for example: a small amount of labor day Maifu Pi feeding porridge, drink lots of water on day 1 after birth the full price of 0.5 kg feed, eat green feed after giving birth 2 0.7 kg full price material, green material you can eat delivery 3 to 5 days after the full price of 1 kg of material, green material can eat delivery 5 to 7 days after the full price of 1.2 kg material, green material can eat 8 to 32 after birth at full price of 1.1 kg material, green material of any food delivery 33 days after the full increase 1.2 kg material, green material can eat 34 days after birth all increase 0.5 kg material, green material can eat 35 days after birth without the full price of materials, green materials can eat 6 hog raising technology (1) diet structure, boars should concentrate for the pigs, the burden of diet structure changes according to mating, during mating dietary energy and protein feed,[link widoczny dla zalogowanych], feed should be 80 ~ 90%, and other types of Feed accounts for about 10%, non-equipped? species during the energy and protein feed should be reduced to 70 ~ 80%, the rest can be green fodder to meet. (2) feeding technique: dietary intake should be controlled, the daily feeding should be time, and quantity. Generally less than 25 kg body weight, 0.9 kg per head per day, 25 to 30 kg, 1.1 kg, 30 kg or more, 1.5 kg. Volume to an appropriate diet and avoid feeding large volume of feed, to avoid hanging belly of breeding use. Wet spices boar feed forms as well, 2 times a day. Tim feeding ground should be fed less, to improve the boar's appetite and promote digestion.
