Problems solved by technology

However, the fast rate of fat loss in first-parity sows can easily lead to low weaning and estrus rate, which will reduce the annual litter size of sows, affect production efficiency, and is not conducive to the play of reproductive performance of sows

Embodiment

[0025] A method for improving the estrus rate of first litter sows after weaning, comprising the following steps:

[0026] (1) Let the sows eat freely after weaning, and add energy substances such as brown sugar and nutritional substances such as electrolytic multidimensional to the feed;

[0027] (2) The sows of the first litter are weaned and the feed is reduced 3 days before the farrowing room. They are not fed on the day of weaning, and they are placed directly on the sports field. If possible, they can be raised in the sports field or in large pens, and they can eat freely to ensure the feed intake of sows;

[0028] (3) Create a suitable feeling temperature, ensure that the temperature, humidity and ventilation are appropriate, keep the pig house clean, dry and ventilated, and have sufficient drinking water. Do a good job of heatstroke prevention and cooling in summer, and the temperature should not exceed 27°C. Work;

[0029] (4) The correct method of estrus checking. S...

Abstract

The invention relates to a method for increasing the postweaning oestrus rate of one-birth sows. The method includes the steps that 1, self-help feeding is conducted after weaning, and meanwhile energy substances and nutrient substances are added in feed; 2, feed reducing is conducted 3 days before weaning in a delivery room, the sows cannot be fed on the same day of weaning, and the sows can be raised in a playground or a large pigsty if possible, so that self-help feeding is guaranteed; 3, an ideal feeling temperature is created, and it is guaranteed that the temperature, the humidity and the ventilation quantity are appropriate; 4, a corrected oestrus checking method is executed, an apt measure for spurring the sows into oestrus is taken for the sows which fail to conduct oestrus after weaning is completed for 7 days or do not conduct oestrus for a long time, and the measure should include the three aspects of Chinese herbal medicine estrualization, hormone estrualization and stimulus movement. The postweaning oestrus rate of the sows is increased, the workload of breeders can be reduced, working efficiency is effectively improved, the number of elimination sows is decreased, and cost is lowered; besides, the number of non-productive days of the sows can be decreased, and the year productivity of the sows is improved.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for increasing the estrus rate of first-parity sows after weaning. Background technique [0002] For modern large-scale pig farms, the estrus rate of a sow after weaning directly affects the production cost and production performance of the entire pig farm. However, the fast rate of fat loss in first-parity sows can easily lead to low weaning estrus rate, which will reduce the annual litter size of sows, affect production efficiency, and is not conducive to the performance of sows' reproductive performance. Therefore, the weaning estrus rate of first litter sows has always been a problem that pig farm managers pay close attention to. Contents of the invention [0003] The object of the present invention is to provide a method for improving the estrus rate of first-parity sows after weaning. The method can effectively improve the estrus rate of first-par...
