An antibiotic-free Pietrain pig breeding method

Abstract

The invention relates to the field of livestock breeding, and discloses a breeding method for Pietrain pigs without antibiotics, comprising the following aspects: (1) partitioning of pig houses; (2) grouping of feeding; (3) feeding process (4) disease prevention and treatment. The zoning of the pig house is not only conducive to keeping the environment of the pig house clean and clean, but also to ensure a clean and hygienic rest environment. Playing appropriate music has a certain effect on soothing the mood and promoting lactation of the sows; fermented feed converts indigestible macromolecular substances into Small molecule nutrients can enhance the absorption of nutrients for Pietrain pigs and reduce costs; feeding Pietrain pigs at different times at different times not only reduces feed waste, but also feeds sows in special periods with extra meals to increase Nutrition; the biological disinfectant does not contain any harmful chemical substances and will not cause secondary pollution; a healthy and clean breeding environment can improve the immunity of Pietrain pigs, and the entire feeding system does not ingest any antibiotic substances, so people can eat with confidence.

Description

Technical field

[0001] The invention relates to the field of livestock breeding, in particular to an antibiotic-free Pietrain pig breeding method. Background technique

[0002] Pietrain pigs are native to the Brabant province of Belgium. They were backcrossed between French Bayeux crossbred pigs and British Berkshire pigs, and then crossbred with British large white pigs. The main features are high lean meat rate, full rear drive and shoulder muscles, low feed-to-meat ratio, and fast growth. Under better feeding conditions, Pietrain pigs grow rapidly and weigh up to 90-100 kg at the age of 6 months. The economic benefits of raising Pietrain pigs are relatively objective.

[0003] However, traditional Pietrain pigs are large-scale and extensively managed, causing problems such as poor living environment, easy to get sick, and easy infection after illness. Therefore, most farms adopt antibiotics to improve the immunity of Pietrain pigs. , Control the spread of the disease. Althoug...
