Embodiment 1

[0015] A feed additive for increasing the content of immunoglobulin in sow colostrum, which is added by 3% in the diet of sows in late pregnancy (gestation 95 days to parturition), and is prepared according to the following formula. Each component and percentage by weight are:

[0016] Calcium chloride 16.7%, ammonium chloride 3.3%, citric acid 16.7%, magnesium sulfate 0.7%, privet fruit polysaccharide 0.1%, saccharin sodium 0.3%, rice husk powder 1%, zeolite powder 61.2%. Grind calcium chloride, ammonium chloride, citric acid, magnesium sulfate, privet fruit polysaccharide, and sodium saccharin into 60-mesh granules; grind zeolite powder and rice husk powder into 40-mesh granules; Weigh it, then put it into a stainless steel mixer with a mixing uniformity of less than or equal to 5%, stir for 5-10 minutes, and pack it according to the quantity to be a finished product.

Abstract

The invention provides a feed additive for improving the immunoglobulin content in sow colostrum. The feed additive comprises the following ingredients by weight percent: 16.7-32.3% of calcium chloride, 3.3-17.7% of ammonium chloride, 16.7-33.3% of citric acid, 0.7-2% of magnesium sulfate, 0.1-0.3% of ligustrum lucidum polysaccharide, 0.3-0.7% of saccharin sodium salt, 1.0-2.0% of powdered rice hull, and 11.7-61.2% of zeolite powder. The additive can improve the immunoglobulin content in the serum of a sow in latter half of gestation and the immunoglobulin content in post-partum colostrum to further improve the immunity of a piglet in suckling period and weaning period and reduce piglet diarrhea.

Description

technical field [0001] The invention belongs to the application field of agriculture and animal husbandry, and in particular relates to a feed additive for increasing the content of immunoglobulin in colostrum of sows. Background technique [0002] At present, the average number of weaned piglets provided by each sow in my country is 15, which is far lower than the average level of more than 20 piglets in developed countries. Many advanced pig farms in Europe, Canada and the United States are able to produce up to 30 weaned piglets per sow per year. The low annual productivity of sows in pig farms in my country is closely related to the low survival rate of suckling pigs in addition to serious reproductive disorders and fewer healthy piglets. In recent years, piglets under 10 days of age in many pig farms in my country have experienced toxic diarrhea, and the incidence ranges all over the country. For this reason, many people use drugs to control it, but with little effect...
