CATDOLL : Comprehensive guide: How to feed a sow scientifically to improve reproductive efficiency

introduction

Scientific breeding management is an important factor in improving the economic benefits of farms, especially in the pig farming industry, where sow feeding is the key to successful breeding. The correct feeding strategy can not only improve the health of sows, but also affect the reproductive capacity of sows and the survival rate of piglets.

Nutritional requirements of sows

The needs of sows vary according to their physiological state and age, and mainly include the following types of nutrients:

• Energy: Sows need enough energy to maintain daily activities and support reproduction. Cereals are recommended as the main energy source.
• Protein: Protein is an important element to ensure the health of sows and the growth of piglets, especially during pregnancy and lactation. High-quality soybean meal and fish meal are good choices.
• Vitamins: Vitamins A, D, E, etc. are essential for sows, especially during lactation. They can be supplemented through feed additives.
• Minerals: Minerals such as calcium, phosphorus, zinc, etc. are also important to support the sow’s bone and reproductive health.

Feeding strategies for different physiological stages

Sows have different nutritional requirements and feeding strategies at different physiological stages:

1. Pregnancy

In the early stages of pregnancy, the energy requirements of sows are not high, but in the late stages of pregnancy, especially in the last three weeks, the energy requirements increase dramatically. At this time, the proportion of concentrated feed in the feed should be increased to ensure the nutritional needs of the sow and the fetus. Pay attention to avoid excessive obesity during pregnancy.

2. Lactation

The energy and protein requirements of sows are the highest during lactation. High-energy and high-protein feeds are needed at this time to ensure that the sows have sufficient physical strength and milk supply. In addition, it is extremely important to ensure that there is sufficient water, as water is the main component of milk.

3. Early breeding period

In the early stage of mating, sows should be given high-quality feed to improve their physical condition. Ensuring balanced nutrition for sows will directly affect their conception rate and the health level of piglets.

Feed selection and management

Correct feed selection is essential to improve sow production performance. Common feeds include:

• Pellet feed: Compared with bulk feed, pellet feed is easier to digest and absorb, and can increase growth rate and feed conversion rate.
• Silage: Silage is rich in fiber, which can improve intestinal health.
• Homemade feed: Homemade feed is made according to the actual situation of the farm to reduce feed costs and ensure balanced nutrition.

Feeding frequency and method

The feeding frequency of sows should be adjusted according to different physiological states:

• During pregnancy: Feed 2-3 times a day and make sure the feed is fresh.
• During lactation: feeding can be increased to 3-4 times a day to ensure that the sow always gets adequate nutrition.
• Breeding period: Feed 2-3 times a day and pay attention to changes in appetite.

Notes and FAQs

The following points should be noted during sow feeding:

• Regular observation: Regularly observe the health status and eating habits of sows and adjust the feed formula in time.
• Disease prevention: Ensure the hygiene of feed, avoid mildew and contamination, and prevent the occurrence of sow diseases.
• Balanced feeding: Avoid using a single feed and combine various feeds to ensure comprehensive nutrition.

in conclusion

Feeding sows is a systematic project that requires comprehensive consideration of factors such as the sow's physiological stage, nutritional needs, and feeding management. Through standardized management, we can significantly improve the production performance of sows and ultimately increase breeding income.
