Embodiment Construction

[0018] For verifying the application effect of the present invention, carried out following test:

[0019] Using the microecological culture feed additive provided by the invention, the test time is 21 days.

[0020] The experimental grouping design selected (35±1) day-old, average body weight (10.06±1.53kg) healthy three-yuan (Du × long × large) cross-weaned piglets 60, randomly divided into 4 treatments, and each treatment had 3 repetitions. There were 5 animals in each repetition, and there was no significant difference in the initial body weight among the repetition groups (P>0.05).

[0021] Table 1 Experimental design

[0022]

[0023] Diet composition and nutrient level The basal diet was prepared according to the nutritional needs of NRC piglets. The composition and nutrient level of the basal diet are shown in Table 2.

[0024] Feeding and management The experimental pigs were given free access to food and water, routinely immunized, and special personnel were res...

Abstract

A preparation method of a microecological culture feed additive belongs to the technical field of livestock and poultry feed additive. A solid fermentation medium comprises 40% of wheat bran, 10% of corn, 9% of soybean meal, 0.5% of urea, 0.1% of potassium dihydrogen phosphate, 0.1% of sodium dihydrogen phosphate, 0.1% of manganese sulfate, 0.2% of calcium chloride and 40% of water. fermentation strains include plant lactobacillus, bacillus subtilis and saccharomyces cerevisiae in a ratio of 1:2:2. The method comprises the following steps: crushing, sieving, mixing, disinfecting, preparing fermentation bacteria liquid, inoculating fermentation strains and obtaining a finished product. The microecological culture feed additive provided by the invention combines functions of nutrition and health care, has no toxic or side-effect or pollution, and can improve antioxidation capability and immunization function of a weaning pigling, increase daily weight gain of the pigling and forage conversion rate, reduce diarrhoea rate, reduce or prevent pigling weaning stress syndrome and substitute antibiotic additive in forage.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feed additives, and in particular relates to a preparation method of a microecological culture feed additive. Background technique [0002] The early health of piglets plays an important role in improving piglet performance. When piglets are weaned, due to the influence of environmental, nutritional, psychological and other stresses, coupled with the immature development of the digestive system of piglets, the partial secretion of various digestive enzymes is insufficient, often showing loss of appetite, decreased feed intake, indigestion, Slow growth, low feed utilization, decreased disease resistance, increased diarrhea rate, and increased mortality are the so-called "weaning stress syndrome in piglets". The various stress responses of piglets after weaning are a major problem in the pig industry. Diarrhea is one of the most serious diseases of weaned piglets and one of the most ...
