Starting from 75 kg, gilts do not need lean meat too quickly. Therefore, it is necessary to start feeding sows from this weight, and it is best to use special gilt stocks. However, the current feed manufacturers focus on feeding materials. As well as suckling pigs, piglets, and middle pigs, these are the bricks that are most likely to open the closed door in the heart of the pig farmers, and they are easy to come out quickly. The pregnant sow is one of the balanced profits of the feed manufacturers. point. After changing from 75 kg to sow material, it is better to evaluate the condition of the gilts fed for half a month. Don't be too fat or too thin. The feed manufacturers recommend reducing the amount of fat and increasing the amount of feed. The amount of feed, the author personally think that this is extremely unfavorable for the gastrointestinal digestive capacity of gilts, if the fertilizer to reduce the amount of feed, over time, the pig's gastrointestinal digestibility to adapt to a small amount of feed, which for the later breastfeeding stage mining Food intake has a large impact. The author's personal approach is to adjust the formula of the feed instead of reducing the amount of feed. The gilts need to be vaccinated and boared after 105 kg. The types of vaccination include swine fever, blue ear, parvovirus, pseudorabies, Japanese encephalitis, streptococcus, etc. The inoculation time for swine and blue ear is the highest. A good interval of 15 days or more, and other vaccines have an interval of 5-7 days. Once the gilts have their first estrus, accurate time must be recorded in order to master the average estrus cycle of the sow, which will help to more accurately grasp the breeding time of the sow, in order to obtain more litter size. In the 15 days before the breeding is determined, the high-energy, high-protein feed can be given assaulting and feeding, and about 1 piglet can be produced. The sow's feeding amount was adjusted from 3 kg to 2-2,5 kg one day before the expected date of production. During this period, many feed manufacturers recommended that the material be reduced from 7 days before birth and 2 kg before 1 day before delivery. The author personally thinks this is misleading. If the sow eats less, due to insufficient energy intake during the farrowing process, the calving process is prolonged and the piglet is killed. Sows are fed after giving birth as far as possible, and the arguments of “experts and professors†cannot be copied mechanically. The specific amount of feed should be based on the premise that "the sow cannot be overeating." The main point of managing sows is to maintain a reasonable body condition and ensure adequate supply of trace elements and vitamins. Three times a day after weaning, boars are used to seduce and quarrel, and Duroc boars are preferred. 400G Salted Black Bean With Salted Ginger Canned Black Fermented Beans,Canned Fermented Black Bean Ginger,Can Fermented Black Bean Ginger,Can Black Bean Ginger jiangmen city hongsing food co., ltd. , https://www.jmhongsing.com
