Feeding and management methods of reserve sows

Gilts are popularly referred to as sows that do not participate in breeding after selection. Generally speaking, gilts are basically used to supplement older, reproductive capacity degradation of the culled sow. This can improve the finishing quality of sow groups, thereby improving the economic benefits of breeding. So in the breeding process, how should the gilts be raised? Is there anything special you should pay attention to? Let's learn together.

1. Group feeding

After feeding sows, we are feeding them. According to its size, strength to group breeding. Generally speaking, small groups are bred according to three to five heads in a column, so grouping can be said to be the most grouping method. Of course, if the breeding site is expanding and the number of gilts is large, we can also raise a few more gilts per pen, but not more than ten at most.

2. Feeding

There is a distinction between gilt feeding and sow feeding or young pig feeding. First of all, we must ensure that the feed is fresh and does not deteriorate. Secondly, it is forbidden to use feed with excessive copper and zinc elements, which will fatten the sows and affect the reproductive ability of the gilts. When feeding, the daily feed amount is generally controlled at about five catties, and it cannot be fed at one time, but it needs to be fed several times. There is also a need to maintain adequate drinking water in the pen during breeding, and at the same time, we need to allow the gilts to exercise properly, which can enhance their physique and reduce the rate of dystocia.

3. Estrus before breeding

The gilt is ovulated prior to breeding, primarily to increase her ovulation rate, thereby increasing the chances of conception and ultimately improving piglet yield. Estrus is best carried out about fourteen days before breeding, mainly through the way of superior feeding. In the amount of feeding before, feed about six jin per day, let gilts feed ad libitum. After breeding, there is a need to reduce the amount of breeding, as far as possible to control about four pounds per day. Feeding during this period is critical, and improper feeding can lead to embryo death. In order to ensure the weight of piglets, then in two months and twenty-five days, the daily feed amount increased to about seven jin.

4. Daily management

The daily management of gilts is actually relatively simple, first of all, to keep the sanitary environment in the farm clean and tidy; secondly, to disinfect irregularly, and at the same time, the temperature in the farm is controlled at about 20 degrees, to maintain good air circulation; there is also reasonable vaccination, so that the effect of strong female can be achieved.

5. Precautions

When breeding gilts, we need to pay attention to the selection and retention of gilts and the introduction of gilts. The second is to do a good job in inducing, breeding and insect control; there is also to determine the feeding plan, using short-term superior feeding and single-match compound and double-match methods, which can play a very important role in sow production.

The breeding of gilts is actually very simple. As long as we master certain breeding skills and solve the precautions perfectly in the breeding process, the productivity of gilts will be improved naturally, and the economic benefits of farmers will be improved.
