Problems solved by technology

[0002] Whether the body condition of sows is reasonable or not at each stage of pregnancy is crucial to their reproductive performance. Currently, lean-meat high-yielding sows generally adopt high, low, and high feed mode feeding during pregnancy, that is, high, Low and high feed volume, the use of this mode is mainly based on the fact that high-yield sows have many litters and many litters in the farrowing room. The nutritional intake of sows during lactation is difficult to meet the needs of lactation, so the use of body storage will lead to overdraft of sow weight and backfat. Sows are often lean at re-weaning and need increased nutrient supply early in gestation to recover
For sows that are too fat during re-breeding after weaning, they are worried that using high feed will make the sow fatter, so they will often lower the feed, but when fed with low feed, the sow will lose fat and affect the farrowing, resulting in sows High and stable production is affected

Embodiment 1

[0014] A total of 97 weaned re-breeding sows with a P2 backfat of 14-15mm were selected from the same farm. The amount of feed fed per day was 2.3kg (the net energy level of the feed was 2350kcal / kg), 2.1kg (the net energy level of the feed was 2350kcal / kg), 2.6kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was The net energy level was 2500kcal / kg) for feeding, and the changes in body condition and litter performance were counted.

Embodiment 2

[0016] A total of 74 weaned re-breeding sows with P2 backfat between 15-16mm were selected from the same pig farm. The amount of feed fed per day was 2.3kg (the net energy level of the feed was 2350kcal / kg), 2.1kg (the net energy level of the feed was 2350kcal / kg), 2.6kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was The net energy level was 2500kcal / kg) for feeding, and the changes in body condition and litter performance were counted.

Embodiment 3

[0018] A total of 82 weaned re-breeding sows with P2 backfat between 16-17mm were selected from the same pig farm. The amount of feed fed per day was 2.3kg (the net energy level of the feed was 2350kcal / kg), 2.1kg (the net energy level of the feed was 2350kcal / kg), 2.6kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was 2350kcal / kg) and 3.5kg (the net energy level of the feed was The net energy level was 2500kcal / kg) for feeding, and the changes in body condition and litter performance were counted.

Abstract

The invention relates to the technical field of livestock breeding and particularly discloses a method for feeding lean type gestational sows. The method includes: feeding all of the lean type gestational sows in an early gestation stage according to a high-feed-quantity standard no matter the sows are fat or thin in mating; on the premise that the sows are guaranteed against weight losing, feeding the sows in a middle gestation stage according to a low-feed-quantity standard to prevent excessively fast back fact accumulation which affects mammary gland development; keeping feeding the sows in a later gestation stage according to the high-feed-quantity standard to meet demands of fetuses. A high-feed-quantity range refers to that the feed quality in the early gestation stage is 2.3-3.0kg, and the net energy level is 2200-2400kcal / kg; the feed quality in the later gestation stage is 2.5-3.8kg, and the net energy level is 2300-2600kcal / kg. A low-feed-quantity range refers to that the feed quality in the middle gestation stage is 2.0-2.2kg, and the net energy level is 2200-2400kcal / kg. The method for feeding the lean type gestational sows is simple, practical and conducive to high and stable fertility of the sows.

Currently, lean-meat high-yielding sows generally adopt high, low, and high feed mode feeding during pregnancy, that is, high, Low and high feed volume, the use of this mode is mainly based on the fact that high-yield sows have many litters and many litters in the farrowing room. The nutritional intake of sows during lactation is difficult to meet the needs of lactation, so the use of body storage will lead to overdraft of sow weight and backfat. Sows are usually lean at re-weaning and need increased nutritional supply early in gestation to regain fitness. For sows that are too fat during re-breeding after weaning, they are worried that using high feed will make t...
