Embodiment 1

[0069] A feeding method for improving the reproductive quality of sows, comprising the following steps:

[0070] step one:

[0071] From estrus to mating to the 8th day, feed sows and piglets Duoduo formula feed gradually from 3 kg / day in the first four days to 2.5 kg / day;

[0072] Step two:

[0073] From the 8th day to the 38th day, feed sows and piglets Duoduo formula feed 2.1-3.0 kg / day. This stage is the golden period for sow body shape adjustment. Adjust the feeding amount according to the backfat thickness of sows;

[0074] Step three:

[0075] From the 39th day to the 85th day, feed the sows Duoduo 2.1-2.3 kg / day. This period is the middle adjustment period of the sows, and adjust the feeding amount according to the backfat thickness of the sows;

[0076] Step four:

[0077] From the 86th day to the 100th day, feed the sows and piglets Duoduo formula feed 3.5 kg / day. This period is one month before the sows give birth. The feeding amount should be increased to expan...

Embodiment 2

[0093] A feeding method for improving the reproductive quality of sows, comprising the following steps:

[0094] step one:

[0095] From estrus to mating to the 8th day, feed sows and piglets Duoduo formula feed gradually from 3 kg / day in the first four days to 2.5 kg / day;

[0096] Step two:

[0097] From the 8th day to the 38th day, feed sows and piglets Duoduo formula feed 2.1-3.0 kg / day. This stage is the golden period for sow body shape adjustment. Adjust the feeding amount according to the backfat thickness of sows;

[0098] Step three:

[0099] From the 39th day to the 85th day, feed the sows Duoduo 2.1-2.3 kg / day. This period is the middle adjustment period of the sows, and adjust the feeding amount according to the backfat thickness of the sows;

[0100] Step four:

[0101] From the 86th day to the 100th day, feed the sows and piglets Duoduo formula feed 3.5 kg / day. This period is one month before the sows give birth. The feeding amount should be increased to expan...

Embodiment 3

[0117] A feeding method for improving the reproductive quality of sows, comprising the following steps:

[0118] step one:

[0119] From estrus to mating to the 8th day, feed sows and piglets Duoduo formula feed gradually from 3 kg / day in the first four days to 2.5 kg / day;

[0120] Step two:

[0121] From the 8th day to the 38th day, feed sows and piglets Duoduo formula feed 2.1-3.0 kg / day. This stage is the golden period for sow body shape adjustment. Adjust the feeding amount according to the backfat thickness of sows;

[0122] Step three:

[0123] From the 39th day to the 85th day, feed the sows Duoduo 2.1-2.3 kg / day. This period is the middle adjustment period of the sows, and adjust the feeding amount according to the backfat thickness of the sows;

[0124] Step four:

[0125] From the 86th day to the 100th day, feed the sows and piglets Duoduo formula feed 3.5 kg / day. This period is one month before the sows give birth. The feeding amount should be increased to expan...

Abstract

The invention relates to the field of animal breeding, in particular to a feeding method for improving the propagating quality of sows. The feeding method for improving the propagating quality of the sows aims at solving the problems in the sow feeding process at the present stage according to the sow growth characteristics. By means of the feeding method for improving the propagating quality of the sows, the survival rate of piglets can be effectively increased, the weight of the piglets is even, the number of the weak piglets is small, and the farrow weight is large; weight losses of the sows are small after ablactation is carried out; the sows can be in heat on time at the time five to seven days after ablactation is carried out; the feed intake of the sows is large in the lactation period, and the milk yield of the sows is large; the ablactation weight of the piglets can be 8.5 kg or more when the piglets are 28 days old; the sows are free of constipation; the number of inflammations of the postpartum sows is small, and the sows are healthy; the in-heat rate is low after the sows are hybridized; the marketing time of bred hogs is shortened by 10 days; the life of the sows is prolonged; the annual marketing number of the sows is increased.

Description

technical field [0001] The invention relates to the field of animal feeding, in particular to a feeding method for improving the reproduction quality of sows. Background technique [0002] The purpose of raising sows and increasing the annual productivity of sows is that each sow can provide more healthy piglets a year. [0003] Usually, it mainly starts from the following three aspects [0004] 1. Take effective measures to shorten the lactation period of sows and the interval between weaning and re-breeding of sows; [0005] 2. Increase the litter size of sows; [0006] 3. Improve the survival rate of piglets. [0007] The purpose of improving the annual productivity of sows can be achieved, and then the economic benefits of raising sows and even the overall pig production can be improved. [0008] 1. Take effective measures to shorten the lactation period of sows and the interval between weaning and re-breeding of sows; [0009] There are many reasons for the abnorma...
