Problems solved by technology

This traditional sow feeding mode can effectively improve embryo survival rate and litter size for sows with low reproductive performance, but this mode is aimed at the supply of nutrients for high reproductive performance sows It will be seriously insufficient, and according to research in recent years, it has been found that early pregnancy is the best period for backfat recovery in sows, so too low feed amount in early pregnancy will further affect the efficiency of backfat recovery throughout gestation
In addition, from the perspective of health and animal welfare, traditional gestational sow feed nutrition design and low feeding amount will also make it difficult to maintain the intestinal health of sows, and are more prone to constipation and accumulation of toxins in the body, making Sow reproductive lifespan and reproductive performance are affected

Embodiment 1

[0038] A sow feeding mode for improving the reproductive performance of sows in the present invention is as follows; the sow feed matched with the sow feeding mode includes pre-pregnancy feed, post-pregnancy feed and lactating sow feed;

[0039] (1) The pre-pregnancy feed is prepared according to the following proportions: 40% corn, 5% soybean meal, 13% bran, 5% full-fat rice bran, 15% soybean hull, 5% corn germ meal, 13% secondary flour, phosphoric acid Hydrogen calcium 0.6%, stone powder 1.4%, premix 2%. The net energy level of the complete feed formula is 2100-2150kcal / kg, the crude protein content is 13-13.5%, and the digestible lysine content is 0.5-0.55%; the ratio of net energy / digestible lysine*1000 is 3.82- 4.3 range.

[0040] After mating, multiparous sows are kept in the positioning pen of the gestation house. During the 0-5 days of gestation, each sow is fed 2.2 kg of the pre-pregnancy feed per day, and the pre-pregnancy feed is used during the 6-50 days of pregna...

Embodiment 2

[0048] A sow feeding mode for improving the reproductive performance of sows in the present invention is as follows; the sow feed matched with the sow feeding mode includes pre-pregnancy feed, post-pregnancy feed and lactating sow feed;

[0049] (1) The pre-pregnancy feed is prepared according to the following proportions: 44.7% corn, 6.5% soybean meal, 8% bran, 10% full-fat rice bran, 10% soybean hull, 9% corn germ meal, 8% corn flour, phosphoric acid Hydrogen calcium 0.5%, stone powder 1.3%, premix 2%. The net energy level of the complete feed formula is 2100-2150kcal / kg, the crude protein content is 13-13.5%, and the digestible lysine content is 0.5-0.55%; the ratio of net energy / digestible lysine*1000 is 3.82- 4.3 range.

[0050] After mating, multiparous sows are kept in the positioning pen of the gestation house. During 0-5 days of gestation, each sow is fed 2.0 kg of the pre-pregnancy feed per day, and the pre-pregnancy feed is used during the 6-50 days of pregnancy. ...

Embodiment 3

[0058] A sow feeding mode for improving the reproductive performance of sows in the present invention is as follows; the sow feed matched with the sow feeding mode includes pre-pregnancy feed, post-pregnancy feed and lactating sow feed;

[0059] (1) The pre-pregnancy feed is prepared according to the following proportions: 50% corn, 10.5% soybean meal, 9% bran, 6% full-fat rice bran, 12% soybean hull, 3% corn germ meal, 5% secondary flour, phosphoric acid Hydrogen calcium 1.3%, stone powder 1.2%, premix 2%. The net energy level of the complete feed formula is 2100-2150kcal / kg, the crude protein content is 13-13.5%, and the digestible lysine content is 0.5-0.55%; the ratio of net energy / digestible lysine*1000 is 3.82- 4.3 range.

[0060] Use first-born sows, within 0-50 days after mating, that is, within 0-50 days of pregnancy, feed the matching pre-pregnancy feed, and feed 2.3kg.

[0061] At 50 days of gestation, use a backfat meter to test the backfat of all sows; within 51...

Abstract

The invention discloses a sow feeding mode for improving the sow breeding performance and a matched sow feed. According to the feeding mode, after multiparous sows are bred, feed is restricted strictly within 0-5 d, the feeding amount of matched feed at the pregnancy earlier stage is 2-2.2 kg, and at 6-50 d of the gestation period, the feeding amount is increased to 2.5-2.7 kg; within 51-85 d of the sow gestation period, the matched feed of the pregnancy earlier stage is fed, 2.3-2.5 kg of the feed is fed to each sow, a back fat instrument is adopted for monitoring the thickness of sow back fat to be 16-18 mm; the feeding amount is corresponding decreased or increased by 0.2-0.3 kg every time the thickness of the back fat is 1 mm lower than or large than 16-18 mm. Compared with the sow feed matched with the sow feeding mode, the feed includes the pregnancy earlier stage feed, the pregnancy later stage feed and the milking sow feed. The propagation characteristics of the stages of the sows are combined, feeding programs and feed nutrients meeting the sow breeding requirements are applied, and the sow breeding performance and health degree thereof can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of sow feed, and in particular relates to a sow feeding mode for improving the reproductive performance of sows and a matching sow feed. Background technique [0002] In recent years, with the continuous development and deepening of research on pig breeding technology at home and abroad, the reproductive performance of sows has been significantly improved. Especially in terms of farrowing performance of sows, the sows in the past have raised 10-11 piglets to 14-15 piglets. At the same time, the improvement and improvement of the feeding management level in the pig industry has also enabled the reproductive performance potential of the above-mentioned sows to be fully utilized. However, another direction of pig breeding technology is to increase the lean meat rate of commercial pigs and reduce the backfat thickness. Many foreign studies and practices have shown that there is a strong correlation between the...
