Problems solved by technology

Although high doses of zinc oxide can improve the growth performance of weaned piglets by regulating the intestinal microbial flora of piglets, and significantly reduce diarrhea in weaned piglets, however, excessive use of zinc oxide will cause environmental pollution problems

Embodiment 1

[0021] Embodiment 1 The preparation of no antibiotic feed

[0022] An antibiotic-free feed for improving the feed intake of weaned piglets. The antibiotic-free feed includes the following components in parts by weight: 200 parts of corn, 150 parts of puffed corn, 20 parts of broken rice, 30 parts of puffed broken rice, soybean protein concentrate 90 parts, 45 parts of puffed soybean, 40 parts of fermented soybean meal, 30 parts of soybean meal, 50 parts of fish meal, 100 parts of whey powder, 30 parts of whole milk powder, 10 parts of yeast hydrolyzate, 50 parts of coconut oil, 10 parts of soybean oil, sugar 90 parts of stew, 4 parts of stone powder, 3 parts of calcium dihydrogen phosphate, 1 part of choline chloride, 8 parts of amino acid, 5 parts of glutamine, 0.5 parts of multivitamins, 10 parts of compound trace elements, 3 parts of compound acidifier, lactic acid 15 parts, 0.5 parts of compound enzyme preparation, 1 part of probiotics, 5 parts of Chinese herbal medicine p...

Embodiment 2

[0025] Effect of Example 2 on production performance and diarrhea rate of weaned piglets

[0026] Taking 21-day-old weaned piglets as experimental animals, they were divided into 2 groups by random block design, with 6 repetitions in each group and 15 piglets in each repetition. The control group was fed with ordinary piglet creep feed, and the experimental group was fed with Example 1 Feed, the test period is 7 days, and the average daily feed intake, daily weight gain and diarrhea index of piglets are investigated. The results are shown in Table 1. The results showed that compared with the control group, the experimental group significantly increased the body weight, average daily gain and average feed intake of the piglets at 7 days after weaning, significantly improved the feed conversion efficiency, and significantly reduced the diarrhea of ​​the weaned piglets.

[0027] Table 1 The present invention is on the impact of weaned piglet production performance and diarrhea r...

Embodiment 3

[0030] Effect of Example 3 on nutrient digestibility of weaned piglets

[0031] The 21-day-old weaned piglets were experimental animals, and they were divided into 2 groups by random block design, with 6 repetitions in each group and 15 piglets in each repetition. The control group was fed with common piglet creep feed, and the test group was fed with Example 1. 1 feed, the test period was 7 days, and the nutrient digestibility of piglets was investigated. The results are shown in Table 2. The results showed that the experimental group significantly increased the apparent digestibility of crude fat and crude ash in the diet.

[0032] Table 2 The present invention is on the influence (%) of weaned piglet nutrient digestibility

Abstract

The invention discloses an antibiotic-free feed capable of increasing food consumption of weaned piglets. The antibiotic-free feed comprises the following components in parts by weight: 200 parts of corn, 150 parts of puffed corn, 20 parts of broken rice, 30 parts of puffed broken rice, 90 parts of soy protein concentrate, 45 parts of puffed soybeans, 40 parts of fermented soybean meal, 30 parts of soybean meal, 50 parts of fish meal, 100 parts of whey powder, 30 parts of whole milk powder, 10 parts of yeast hydrolyate, 50 parts of coconut oil, 10 parts of soybean oil, 90 parts of carbohydrate, 4 parts of stone powder, 3 parts of calcium dihydrogen phosphate, 1 part of choline chloride, 8 parts of amino acids, 5 parts of glutamine, 0.5 part of composite vitamins, 10 parts of composite trace elements, 3 parts of a composite acidulant, 15 parts of lactic acid, 0.5 part of a compound enzyme preparation, 1 part of prebiotics and 5 parts of a Chinese herbal medicine preparation. The feed obviously increases the growth properties and the health level of piglets a week after weaning.

Description

technical field [0001] The invention belongs to the technical field of pig breeding feed, and in particular relates to an antibiotic-free feed for improving feed intake of weaned piglets. Background technique [0002] Weaning is a crucial stage in the growth and development of piglets. Due to weaning stress, the feed intake of weaned piglets decreases, resulting in structural damage and dysfunction of the intestinal tract of piglets, often resulting in growth stagnation and severe diarrhea. Growth performance one week after weaning affects piglet performance later on and time to market. The results of related research at Ohio State University show that within one week of weaning, piglets eat an additional 0.1kg of feed per day, and their body weight can increase by about 1.5kg after the fourth week of weaning. Feed intake reduction caused by weaning stress will lead to stunted intestinal development in piglets, shortened villi length, deepened crypt depth, increased loss of...
