Problems solved by technology

[0002] Landrace pig is a world-renowned lean-meat pig breed. Its main advantages are large litter size, fast growth and development, feed saving, and high carcass lean meat rate. However, it has poor stress resistance and has high requirements for feed nutrition. For the fattening of Landrace pigs, hormones and a large amount of concentrated feed will be added during the fattening process of traditional Landrace pigs to reduce the disease resistance of Landrace pigs and increase the use of antibiotics, resulting in hormone and antibiotic residues in fattening pigs, and a decrease in lean meat percentage. Pork quality, therefore, requires a green, healthy and fast fattening method for Landrace pigs

Embodiment 1

[0019] A fattening method for landrace pigs, comprising the following steps:

[0020] (1) Piglet placement: Clean and disinfect the fattening house before the piglets are housed, divide the piglets according to their size, and feed them in the same fattening house, so that the fattening Landrace pigs can eat feed evenly and grow at a similar rate. It is easy to manage, and can be slaughtered at the same time to obtain growing pigs;

[0021] (2) Rapid increase in the early stage: in the early stage of fattening, feeding the growing pigs with the early stage feed, 4 times a day, ad libitum, and feeding roughage once in the middle. Second, the drinking water temperature in the early stage is 25~27℃, the corn content is high, the roughage is less, and the concentrated feed is fed multiple times, and the water temperature of the drinking water is high, which can promote the fat growth of fattening pigs, and the increase is the fat growth of the whole fattening period. 62-64% of th...

Embodiment 2

[0032] A fattening method for landrace pigs, comprising the following steps:

[0033] (1) Piglet placement: Clean and disinfect the fattening house before the piglets are housed, divide the piglets according to their size, and feed them in the same fattening house, so that the fattening Landrace pigs can eat feed evenly and grow at a similar rate. It is easy to manage, and can be slaughtered at the same time to obtain growing pigs;

[0034] (2) Rapid increase in the early stage: in the early stage of fattening, feeding the growing pigs with the early stage feed, 4 times a day, ad libitum, and feeding the roughage once in the middle. The feeding amount of the roughage is 9% of the weight of the early stage feed throughout the day. Second, the drinking water temperature in the early stage is 25~27℃, the corn content is high, the roughage is less, and the concentrated feed is fed multiple times, and the water temperature of the drinking water is high, which can promote the fat gr...

Embodiment 3

[0045] A fattening method for landrace pigs, comprising the following steps:

[0046] (1) Piglet placement: Clean and disinfect the fattening house before the piglets are housed, divide the piglets according to their size, and feed them in the same fattening house, so that the fattening Landrace pigs can eat feed evenly and grow at a similar rate. It is easy to manage, and can be slaughtered at the same time to obtain growing pigs;

[0047] (2) Rapid increase in the early stage: in the early stage of fattening, feeding the growing pigs with the pre-feed, 5 times a day, ad libitum, and feeding roughage once in the middle. Second, the drinking water temperature in the early stage is 25~27℃, the corn content is high, the roughage is less, and the concentrated feed is fed multiple times, and the water temperature of the drinking water is high, which can promote the fat growth of fattening pigs, and the increase is the fat growth of the whole fattening period. 62-64% of the fatten...

Abstract

The invention mainly relates to the technical field of pig raising, and discloses a fattening method of landrace pigs. The method comprises the steps of putting young pigs into pig houses, quickly increasing the weight of the pigs in the early period, slowly increasing the weight of the pigs in the middle period and stabilizing the weight of the pigs in the late period. Feeding is conducted in different stages, and the method is simple and easy to operate; with 100 kg taken as the standard of the weight of the fattened pigs, the fattening time of the landrace pigs is shortened to be 88 days, and the lean meat percentage is 70.4%; plant-derived antimicrobial agents are added in fodder, so that the disease resistance capability of the fattened pigs is improved; no hormone or antibiotic is used in the whole process, so that residues of hormones and antibiotics in pork are avoided, and the pork is safe and healthy; the landrace pigs are put into different pig houses according to individual sizes, the pigs with the same size are fed in the same fattening pig house, so that the fattened landrace pigs can be uniformly fed with fodder, the growth speed is uniform, the management is facilitated, and slaughtering can be conducted at the same time.

Description

technical field [0001] The invention mainly relates to the technical field of pig raising, in particular to a fattening method for Landrace pigs. Background technique [0002] Landrace pig is a world-renowned lean-meat pig breed. Its main advantages are large litter size, fast growth and development, low feed consumption, and high lean carcass rate, but poor resistance to stress and high nutritional requirements for feed. Therefore, in order to speed up In the fattening of landrace pigs, hormones and a large amount of concentrated feed will be added in the fattening process of traditional landrace pigs, which will reduce the disease resistance of landrace pigs, increase the use of antibiotics, cause the residual hormones and antibiotics in fattening pigs, and reduce the lean meat rate. Pork quality, therefore, requires a green, healthy and fast fattening method for landrace pigs. SUMMARY OF THE INVENTION [0003] In order to make up for the defects of the prior art, the p...
