Problems solved by technology

The main advantages are large litter size, fast growth and development, feed saving, high carcass lean meat rate, etc., but poor stress resistance and high nutritional requirements for feed
Landrace pork has excellent quality and high lean meat percentage, and is an important meat-providing pig. However, Landrace pigs are weak in physique, poor in stress resistance, and prone to reproductive disorders and cracked hooves.
[0003] Landrace pigs need to be castrated during the growth process to increase the growth rate of the pigs. However, within half a month to one month after the castration treatment, the growth will be slow, or even stop growing, and severe cases will cause infection and death.

Embodiment 1

[0020] A breeding method for landrace pigs, comprising the following processing steps:

[0021] (1) Castration of piglets; piglets were castrated when they were 5 days old. Before castration, piglets were fed with 35ml of saline solution with a mass fraction of 5%, and fed with compound milk powder 3 days before castration. At the end of 3 days after castration, the compound milk powder consists of: 32 parts of whole milk powder, 6 parts of black sesame powder, 4 parts of honey, 2.5 parts of white sugar, 0.58 parts of poria cocos, 1.3 parts of honeysuckle, 0.25 parts of Panax notoginseng , Magnolia officinalis 0.7, and Eucommia ulmoides 0.8; before castration, inject high-concentration saline and use whole milk powder compounded with traditional Chinese medicine to cooperate with breastfeeding, which can greatly enhance the anti-infection ability of piglets and prevent the occurrence of piglets caused by castration. Infection causes slow growth or even death. Castration is per...

Embodiment 2

[0031] A breeding method for landrace pigs, comprising the following treatments:

[0032] (1) Castration of piglets; piglets were castrated when they were 5 days old. Before castration, piglets were fed with 40ml of saline solution with a mass fraction of 5%, and fed with compound milk powder 3 days before castration. At the end of 3 days after castration, the compound milk powder consists of: 35 parts of whole milk powder, 7 parts of black sesame powder, 3 parts of honey, 2.2 parts of white sugar, 0.55 parts of poria cocos, 1.3 parts of honeysuckle, 0.24 parts of Panax notoginseng , Magnolia officinalis 0.7 part, Eucommia 0.9 part;

[0033] (2) Piglets are weaned; the piglets are weaned at the age of 42 days, starting 5 days before weaning, fed with nutrient feed with breast milk, fed with nutrient feed twice a day, 90g each time; after weaning, all use nutrient feed Feed feeding, nutritional feed is made of the following raw materials by weight: 32 parts of skimmed milk pow...

Abstract

The invention relates to a landrace breeding method. The method comprises the following processing steps: (1) castrating piglets; (2) weaning the piglets; (3) when the pigs are 60-120 days old, feeding the pigs with a feed containing the following raw materials in parts by weight: 35 parts of wheat bran, 18 parts of pumpkin powder, 4.5 parts of bone powder, 11 parts of soybean cakes, 3 parts of red beans, 9 parts of rape seed cakes, 15 parts of brewer's grains, 2 parts of duck blood powder, 7 parts of vinegar residues, 5 parts of barley powder, 0.01 part of compound vitamin, 0.02 part of compound amino acid and 0.01 part of compound trace elements; (4) when the pigs are older than 121 days, feeding the pigs with other compound feeds. The method has the beneficial effects that the growth rate of the landrace can be further increased and the health care value of the pork can be improved by using different feeds and processing modes in the growing period of the landrace.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a breeding method for Landrace pigs. Background technique [0002] Landrace pig originates in Denmark and is a world-renowned lean-meat pig breed. The main advantages are large litter size, fast growth and development, feed saving, high carcass lean meat rate, etc., but poor stress resistance and high nutritional requirements for feed. Landrace pork has excellent quality and high lean meat rate, and is an important meat-providing pig. However, Landrace pigs are weak in physique, poor in stress resistance, and prone to reproductive disorders and cracked hooves. [0003] Landrace pigs need to be castrated during the growth process to increase the growth rate of the pigs. However, within half a month to one month after castration, the growth will be slow, or even stop growing, and severe cases will cause infection and death. Contents of the invention [0004] The purpose of t...
