example 1

[0031] According to the principle of similar weight, age and sex ratio, 40 Du long-term hybrid fattening pigs with a body weight of 50.10±0.50kg were selected and randomly divided into a control group and an experimental group, with 5 replicates in each group and 4 pigs in each replicate. The diet of the control group is a typical corn-soybean meal type dry powder diet commonly used in current production, and the jujube diet of the present invention in the test group. The formal trial period is 61 days. After the test started, the concentrations of ammonia and hydrogen sulfide in the piggery were measured once a week. After the test for 30 days, blood was collected from the anterior vena cava at 8:00 on an empty stomach. Antioxidant capacity (T-AOC) index. The feces of each pig were collected one day before the end of the test, and the contents of nitrogen, phosphorus, copper, iron, zinc and manganese in the pig manure were determined. The experiment was carried out in Jiyan...

example 2

[0049] According to the principle of similar body weight, age and sex ratio, select pens of 100 pigs of Du long-term hybrid fattening pigs with a body weight of 62.35±0.50 kg, and randomly divide them into a control group and an experimental group. The diet of the control group is a typical corn-soybean meal type dry powder diet commonly used in current production, and the jujube diet of the present invention in the test group. The formal trial period is 45 days. The feces of each pig were collected one day before the end of the experiment, and the contents of nitrogen, copper, iron, zinc and manganese in the pig manure were determined. The experiment was carried out at Leling Pig Farm. The pigs in each group were free to eat, and the feeding and management of the pigs in each group were the same.

[0050] The diet of the control group: with reference to the national industry standard (NY / T 65-2004), the corn-soybean meal diet was formulated as follows: 60.0% corn, 15.0% soy...

Abstract

The invention discloses a method for utilizing fresh jujube fermentation to prepare a pig feed. According to the method, whole fresh jujubes are used as main raw materials and are compounded with peanut meal, tea meal, DDGS, lysine residues, composite trace elements and compound vitamins; the microbial additive prepared from enterococcus faecium, bacillus natto, candida utilis and trichoderma longibrachiatum are added, and sealed anaerobic fermentation is performed at the temperature of 16-23 DEG C for 5 days, and then fermentation succeeds; it is detected that the flavonoid content in the feed after fermentation is greater than 2000 mg / kg, and the cyclic adenosine monophosphate content is greater than 7.0 mg / kg. The fermented feed can be used for feeding pigs, improves the production performance and immune functions of pigs and reduces the influence of the concentration of ammonia and hydrogen sulfide in a piggery and the mineral element content in pig manure content, and the feed cost is reduced.

Description

technical field [0001] The invention relates to a method for preparing pig feed by fermenting fresh dates, belonging to the technical field of animal husbandry. Background technique [0002] Pigs are the first of the six livestock, and pork prices and pork safety have seriously affected people's lives. At present, my country's intensive pig farming industry is facing several key limiting factors: First, the price of bulk conventional feed materials such as corn and soybean meal has risen, which has reduced the efficiency of pig farming. As the main raw material of pig feed, corn is generally added in an amount of 60-70% in full-price feed, and its price fluctuations affect the economic benefits of raising pigs. Corn prices have risen by more than 20 percent in recent years, leading to increased feed production costs. At the same time, unconventional feeds such as peanut meal and tea meal are cheap and rich in resources, but the digestibility of unconventional feed material...
