Embodiment 1

[0034] The management method of feeding sows according to the backfat ratio is carried out step by step according to the following stages:

[0035] Phase 1: After the sow is weaned:

[0036] At this stage, it is not necessary to use an electronic backfat tester to measure the body condition of sows. The routine feeding amount of each sow to be mated is 3 kg of feed per day, and the gilts are free to eat;

[0037] The second stage: 1-30 days of pregnancy after mating:

[0038] Multiparous sows: After mating, measure the sows’ body condition with a practical electronic backfat tester. The backfat of multiparous sows is 16 mm to 18 mm. The daily feeding amount of each sow is 1.4 kg of feed ,

[0039] After mating, measure the body condition of sows with a practical electronic backfat tester. The backfat of sows is below 16 mm. The daily feeding amount of each head is 0.2 kg / mm ​​of feed on the basis of the conventional feeding amount. The maximum amount of feed per head per da...

Embodiment 2

[0057] The management method of feeding sows according to the backfat ratio is carried out step by step according to the following stages:

[0058] Phase 1: After the sow is weaned:

[0059] At this stage, it is not necessary to use an electronic backfat tester to measure the body condition of sows. The routine feeding amount of each sow to be mated is 3.5 kg of feed per day, and the gilts are free to eat;

[0060] The second stage: 1-30 days of pregnancy after mating:

[0061] Multiparous sows: After mating, measure the sow's body condition with a practical electronic backfat tester. The backfat of the multiparous sows is 16mm-18mm. The daily feeding amount of each sow is 1.8 kg of feed ,

[0062] After mating, measure the body condition of sows with a practical electronic backfat tester. The backfat of sows is below 16 mm. The daily feeding amount of each head is 0.2 kg / mm ​​of feed on the basis of the conventional feeding amount. The maximum amount of feed per head per d...

Embodiment 3

[0080] The management method of feeding sows according to the backfat ratio is carried out step by step according to the following stages:

[0081] Phase 1: After the sow is weaned:

[0082] At this stage, it is not necessary to use an electronic backfat tester to measure the body condition of the sows. The daily feeding amount of each sow to be mated is 3.3 kg of feed, and the gilts are free to eat;

[0083] The second stage: 1-30 days of pregnancy after mating:

[0084] Multiparous sows: After mating, measure the sow's body condition with a practical electronic backfat tester. The backfat of multiparous sows is 16 mm to 18 mm. The daily feeding amount of each sow is 1.6 kg of feed ,

[0085] After mating, measure the body condition of sows with a practical electronic backfat tester. The backfat of sows is below 16 mm. The daily feeding amount of each head is 0.2 kg / mm ​​of feed on the basis of the conventional feeding amount. The maximum amount of feed per head per day is...

Abstract

The present invention provides a management method for quantitatively feeding sows based on backfat, which is carried out step by step according to the following stages: the first stage: after the sow is weaned, the second stage: 1-30 days of pregnancy after mating, the third stage: 31-31 days of pregnancy 85 days, the fourth stage: after 85 days of gestation and the fifth stage: after giving birth. Adopting the management method of the present invention to raise sows can adjust the body condition of individual sows to the best state, so that the overall pig population is uniform and healthy, and feeding with evidence can reduce the waste of feed caused by blind feeding, and promote the development of newborn piglets. The weight of the sow is uniform and reasonable, which promotes the maximum productivity of sows and prolongs the reasonable service life of sows.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a management method for quantitatively feeding sows according to backfat. Background technique [0002] Pig farming is an important industry in my country's agriculture. It plays an important role in ensuring the safe supply of meat food. At present, my country's pig industry is transforming from traditional pig industry to modern pig industry. No matter the breeding mode, regional layout, production mode and production capacity are undergoing significant changes. There are many challenges such as weak independent innovation ability, prominent food safety problems, rising labor costs, dependence on imports of original species, serious epidemic diseases, high pressure on environmental protection, and lack of feed resources. [0003] In the feeding and management process of basic sows, the feeding amount of sows at each stage has been clearly stipulated in the past. When it c...
