Problems solved by technology

However, this method divides the gestation period into five stages, and each stage needs to add and subtract feed in combination with backfat number, labor process and sow category. The calculation and operation process is too complicated, which is not conducive to the actual production operation of sow breeding; and it is aimed at For sows with a certain back label thickness, the feeding amount provides a range value, not precise feeding

Embodiment 1

[0040] Select primiparous sows with backfat≧12mm as primiparous mating sows; select multiparous sows with backfat≧9mm as multiparous mating sows;

[0041] The feed for pregnancy is calculated by weight percentage: 57% corn, 14% soybean meal, 15% bran, 10% sugar beet meal, and 4% premixed feed for pregnant sows.

[0042] Back fat thickness P 2 The measurement method of the point is that the last rib goes up vertically, 6.5cm away from the midline of the back; the time point of backfat measurement is 7 days, 30 days and 60 days after successful mating.

[0043] A refined feeding method for improving the reproductive capacity of pregnant sows is carried out step by step according to the following stages:

[0044] The first stage: 0 to 7 days of pregnancy

[0045] At this stage, it is not necessary to use an electronic backfat tester to measure the body condition of sows, and the feeding amount of each sow to be bred is 1.9kg / day;

Abstract

The invention discloses a refined feeding method capable of improving the reproductive capability of pregnant sows, and belongs to the technical field of sow breeding. According to the refined feedingmethod, a gestation period of the sows is divided into five stages, and feed of a certain amount is put in a targeted mode according to a measured value of backfat, so that nutrition imbalance whichis caused by artificial experience error and blind feeding is reduced, maximization of the productivity of piglet producing of the sows is promoted, and the total piglet rate and living piglet rate ofthe sows are improved. Corn, soybean meal and bran are adopted as base materials of breeding feed, beet pulp and premix of the pregnant sows are added, and the breeding feed has a formula of a reasonable proportion and rich nutrition, so that feeding needs of the sows during the gestation period is met; through the adoption of the refined feeding method in feeding of the pregnant sows, the operation is simple and easy to control, the feeding amount is reasonable and balanced, and fatness of an individual sow can be adjusted to a best condition, so that the body type of a whole sow populationis even and healthy, the control rate of the body type of the sows is improved, and the reasonable life service of piglet producing of the sows is prolonged.

Description

technical field [0001] The invention relates to the technical field of sow breeding, in particular to a refined feeding method for improving the reproductive ability of pregnant sows. Background technique [0002] Pregnant sows refer to sows in the physiological stage of pregnancy. Sows ovulate 22-25 eggs per litter, and 19-21 eggs are finally fertilized. However, the number of live litters in my country is generally only 7-10, which means that nearly half of fertilized eggs die during pregnancy. Why are so many embryos lost during pregnancy? This is related to our feeding mode for pregnant sows in production. For quite a long period of time, sows in my country have generally adopted a low-medium-high feeding mode, failing to provide targeted nutrition according to the weight, body condition, parity, different stages of pregnancy and the different environments of sows at conception. needs and management requirements. In addition, most rural retail households use green feed...
