Description
Technical Field
The invention belongs to the technical field of feed production, and particularly relates to a special feed for weaned pigs and a preparation method thereof.
Background
The live pig breeding is an important component of livestock and poultry breeding, and the quality and the growth speed of piglets are directly related to the slaughtering time and the meat yield of the pigs. In recent years, with the improvement of animal breeds and the progress of breeding techniques, most pig farms have adopted early weaning breeding. Although early weaning has the advantages of promoting early appetizing, improving weight of weaning litter, reducing feed conversion ratio and the like, the requirements on the feed of the weaning piglets are high because the early digestive system of the piglets is underdeveloped in function, low in immune function and easy to cause diarrhea or anorexia.
The newborn piglet has low autoimmune capability and diarrhea caused by environmental temperature change and the like; the weaning can cause oxidative stress of piglets, the gastrointestinal tract structure of the weaned piglets is not developed completely, the digestive enzyme secretion is insufficient, the intestinal lactic acid secretion is reduced, the digestion and absorption of feed nutrients are influenced, the nutritional diarrhea of the piglets is caused, the immunity and the disease resistance are reduced, the growth is influenced, and even the piglets die. The antibiotic is added into the piglet feed, so that the diarrhea rate and the death rate can be effectively reduced, and the growth of piglets is promoted. However, long-term abuse of antibiotics causes drug resistance of bacteria, and drug components in pork remain, so that the eating safety is influenced.
