Embodiment 1

[0017] A feeding and management method for reducing PSE meat of lean pigs. The pigs are raised in a pigsty breeding area, and the feeding of the pigs is divided into three stages. The first stage is the young pig stage, the second stage is the medium pig stage, The third stage is the big pig stage. The weight of each pig in the small pig stage is 5KG~30KG, the weight of each pig in the middle pig stage is 31KG~60KG, and the weight of each pig in the big pig stage is above 61KG. The feeding and management of pigs Consists of the following two parts:

[0018] (1) Feed for piglets: 1) Piglet stage: put in piglet feed twice a day, and the amount of piglet feed per day is 5.2% of the pig's body weight, and the weight percentage of crude protein in the piglet feed is 17.0%; 2) Middle pig stage: feeding medium pig feed 2 times a day, the daily feeding amount of medium pig feed is 4.5% of pig body weight, and the weight percentage of crude protein in the medium pig feed is 16.3%; 3) ...

[0024] A feeding and management method for reducing PSE meat of lean pigs. The pigs are raised in a pigsty breeding area, and the feeding of the pigs is divided into three stages. The first stage is the young pig stage, the second stage is the medium pig stage, The third stage is the big pig stage. The weight of each pig in the small pig stage is 5KG~30KG, the weight of each pig in the middle pig stage is 31KG~60KG, and the weight of each pig in the big pig stage is above 61KG. The feeding and management of pigs Consists of the following two parts:

[0025] (1) Feed for piglets: 1) Piglet stage: put in piglet feed 4 times a day, the daily amount of piglet feed is 5.6% of the pig's body weight, and the weight percentage of crude protein in the piglet feed is 18.5%; 2) Middle pig stage: feeding 4 times a day medium pig feed, the daily feeding amount of medium pig feed is 5.0% of pig body weight, the weight percentage of crude protein in the medium pig feed is 16.8%; 3) Big pig ...

Embodiment 3

[0031] A feeding and management method for reducing PSE meat of lean pigs. The pigs are raised in a pigsty breeding area, and the feeding of the pigs is divided into three stages. The first stage is the young pig stage, the second stage is the medium pig stage, The third stage is the big pig stage. The weight of each pig in the small pig stage is 5KG~30KG, the weight of each pig in the middle pig stage is 31KG~60KG, and the weight of each pig in the big pig stage is above 61KG. The feeding and management of pigs Consists of the following two parts:

[0032] (1) Pig feed: 1) Piglet stage: put piglet feed 3 times a day, the amount of piglet feed is 5.4% of pig body weight per day, and the weight percentage of crude protein in the piglet feed is 17.8%; 2) Medium-sized pig stage: feed medium-sized pigs 3 times a day, the amount of daily medium-sized pig feed is 4.9% of pig body weight, and the weight percentage of crude protein in the medium-sized pig feed is 16.5%; 3) Big pig st...

Abstract

The invention relates to a feeding management method to reduce PSE (pale, soft and exudative) meat in lean pigs. Full feeding is performed in the early stage with high-protein daily ration so that lean weight increasing is effective; fat deposition in the later stage is faster; the lean ratio is continuously decreased; in the later stage of addition, the feeding quantity is increased; therefore, high lean yield can be achieved by limiting the total feeding quantity and controlling fat deposition. Music is played when pigs are bathed, so that the influence of heat stress upon pigs can be effectively reduced, immune reaction and carcass quality can be improved for the pigs, and stress reaction in the pigs is relieved; water temperature and flushing time are reasonably controlled during pig flushing, certain anti-stress effect is created for the pigs, and chances for PSE meat in the lean pigs to occur can be effectively decreased; in pig feed, the addition of suitable sodium selenite andvarious vitamins can effectively relieve body oxidative injury and liver functional damage of animals due to the intake of mycotoxins, selenium deposition in muscle tissues is increased, stress is relieved, and pork quality is improved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding, in particular to a feeding management method for reducing lean pig PSE meat. Background technique [0002] Lean pigs are characterized by fast growth and development, high protein conversion efficiency, and high metabolic intensity. Therefore, when formulating feed, it should follow the law of growth and development of lean-meat pigs. In the early stage, high-protein rations are used for adequate feeding, and the effect of gaining weight and lean meat is good; The amount of food is increased, so the amount of fat deposition can only be controlled by limiting the total amount of food intake, that is, the feeding method of "open front and control later" can achieve the goal of producing more lean meat. [0003] The purpose of raising lean pigs is to provide consumers with high-quality and low-cost pork, and to make producers benefit. In the production of commercial pigs in ...
