The breeding of sows has always been the focus of the farm. The nutritional requirements of the sow's various growth stages are different. We should understand the needs of the sow's growth stage, and then formulate measures to feed the sow's feed to ensure that the sow's healthy nutrition and growth are better.
How do gilts feed? The gilts are in the stage of growth and development. High-quality, nutritious feed is essential for the sow's body development and reproductive system development. In the sow feed selection of less than 6 months of age, the large pig material (full-price pelletized material sold on the market) is 1:1 equipped with green fodder and allowed to freely feed. Sows from the age of 6 months to pre-male breeding chose the full-price pellets for sale on the market and 1:1 for green sows. Cottonseed cake, rapeseed cake, and moldy feed that are harmful to the reproductive system are strictly prohibited at this stage. Appropriate feed restriction to prevent sows from becoming overweight, affecting estrus and ovulation.
How the sow feeds her feed during weaning. Empty period refers to the period from normal weaning to pre-breeding. After sows are generally estrus for about 1 week after weaning, the selection and control of the material at this stage will affect the reproductive cycle of the sow. Empty sows often have weaning stress 1-3 days after weaning, and can easily cause mastitis, high fever and other illnesses. At this time, it is important to control the amount of feed fed daily in combination with fattening sows. Two meals a day, quantitative feeding, must not allow them to freely eat and cause these diseases. The choice of material can not be changed suddenly, should choose the market selling big pig material or empty material, within 3 days after weaning, the nursing material will be gradually replaced by empty material or big pig material. Appropriate increase in laxative bran and succulent green fodder, swine equipment and other health.
How do sows feed during lactation? Lactation refers to the stage of sow giving birth to weaning. The selection and control of feed during lactation is the most important aspect of the entire production process. Sows do not feed on calving day, postpartum feed some warm bran soup + biochemical soup pills (3-5 pills/times) + brown sugar saline, fed twice, to promote the discharge of lochia and quickly restore stamina. On the second day after giving birth, sows are fed about 1 kilogram of feed. After that, 0.5 kilograms of feed is added daily, and the normal amount of food is restored by 4-5 days. After the appetite is normal, the sows are allowed to feed freely to ensure that the piglet sucks enough milk and maintains good reproductive performance. One week before the piglets were weaned, the nursing sows could be gradually reduced and the nursing material gradually replaced with empty material. On the day of weaning, sows feed on a daily basis at 2.4-2.6 kg. In the lactation period, feed materials sold on the market should be selected, and soy oil or dry fat should be added to the feed properly. Green feed should be provided at 1:1.
The sow's feed must be fed well. This not only determines the health of the sow but also determines the health of the piglet, so the feeding requirements for the sow's growth phase must be fulfilled.
