Environmental Control Points in Piglet Conservation Phase
Reduce weaning stress response
The so-called stress response is the intense stress that the piglets have on sudden changes in the environment. Due to the separation of sows and piglets, piglets usually show howling, disturbed, and reduced appetite. Sensitive to abnormal noise, in order to reduce the stimuli, two reductions should be achieved. One is to artificially reduce the number of breast-feeding 2 to 3 days prior to weaning to increase intake, and the second is to reduce the sow's feed nutrients and increase crude fiber to reduce the number of mothers. Pig milk production. "Three invariable", the housing remains unchanged, and the feed does not change. Keepers remain unchanged. When the piglet is weaned, the sow is rushed to the sow house and the piglet is left to transition for 3 to 5 days in the farrowing house. This stage still feeds the milk stage feed. At the same time, it is not appropriate to change the breeder in order to better familiarize with and manage the piglets. .
Timely transfer, reasonable grouping
After weaning, piglets are usually reared in the farrowing room for 3 to 5 days. After the piglets are observed to adapt to the independent feeding environment, they are transferred to the nursery in time and regrouped according to the size of the nursery. The principles to be mastered are: (1) 1 week before the transfer, check whether the food trough, drinking water, and defecation equipment are in good condition, and conduct thorough disinfection to prepare for the transition; (2) According to the piglet age and body Reasonable groupings according to the number of births and births are usually for the piglets of similar age and weight to be grouped together. There are conditions to separate the sow's first-born piglet from the sow's piglet; (3) The piglets from different sources should be divided into groups. Feeding; (4) Each litter has a small body weight and partial gregarious feeding.
Adjust the diet and feed it reasonably
Feeds for piglets during lactation should be palatable, small in size, nutrient-rich, easily digested and absorbed by piglets, and have good crispy and sweet characteristics. To do this: (1) The composition of the diet transitions. After 2-3 weeks, the milk gradually transitioned to the weaning material, after 15 days. The 10% weaning feed was added daily until it was fed completely with weanling piglets because of the protein levels of the weaning feed (especially digestible proteins) and digestive energy. Lower than the feed for pigs; (2) Feeding times for weaned piglets after weaning are not reduced, especially during the first week after weaning, feeding at night is required every day to ensure that each piglet can eat feed, and at the same time pay attention to limited feed to prevent Eating too much causes indigestion. After 2 to 3 weeks, the number of feedings was gradually reduced until normal feeding; (3) Appropriately increased organic acids and antibiotics were added to weaned pigs. To help digestion, to prevent diarrhea; (4) timely replenishment. Water is very important for piglets, and the water head setting is easy for the piglets to find and drink water in time.
Pay attention to pig environment
Weaned piglets, either in the sow house transition or in nursery homes, have a direct impact on the piglet rearing rate and growth rate. Must do the following work: (1) to maintain proper temperature, weaning piglets 30 to 60 days of age, 20 ~ 22 °C is appropriate, can be from high to low, every l 10d reduced l °C, especially in winter to prevent thieves Wind or artificially caused the temperature of the house too low. Humidity of 65% to 5%, too wet, can cause pigs to have a variety of diseases and even cause death; (2) Carefully tuned, piglets transferred to nursery pigs, adjustment work is very important, fixed feeding, excretion, sleeping habits Keeping the foundation of the pig's environment clean. Therefore, the transition must be repeated throughout the week. Establish habits of piglet conditioning. Always observe piglet activity, feed intake, and fecal status and clean it in time. Make sure that the air in the house is clean and the environment is clean and tidy; (3) Actively prevent and treat. The piglets should be protected and dewormed in a timely manner. If a sick pig is found to be isolated and treated, there will be diarrhea. To find out the reasons, generally prevent or replace feed, and avoid individuals from affecting groups.
