Problems solved by technology

[0002] In recent years, with the rapid development of my country's pig industry, the degree of intensification has increased, domestic and foreign livestock and poultry trade has become increasingly frequent, and the chance of disease transmission has increased. Pig farmers generally use feed with additives such as antibiotics, hormones, and chemically synthesized drugs. Long-term use of these feeds will not only easily lead to problems such as drug resistance of pathogenic microorganisms, decline in animal immunity and product quality, but also increase harmful residues in poultry products and the environment, seriously threat to human health

Embodiment 1

[0026] Test one:

[0027] 1. Experimental design

[0028] 2. Material Preparation

[0029] Experimental location: pig farm of Guangxi Animal Husbandry Research Institute.

[0030] Experimental breed: Guike pig.

[0031] Experimental elephant grass / grass: purple elephant grass, Guiminyin elephant grass, alfalfa, kudzu vine.

[0032] Remarks: The purple elephant grass variety in this example is a variety independently selected and bred by the applicant, and has passed the examination and approval of the Guangxi Zhuang Autonomous Region (or the country) at present.

[0033] This variety is introduced from Brazil, and its breeding method is as follows:

[0034] Carry out sexual propagation of Brazilian purple elephant grass, select plants with high grass yield and good quality for asexual propagation by cuttings, and select plants with high yield per plant, high crude protein content, many tillers, large leaf volume, and stems in the multiplication population. Thick, pest-fre...

Embodiment 2

[0063] Test two:

[0064] 420 30-day-old piglets with similar body weight were selected and randomly divided into 14 groups with 3 levels in each group and 10 piglets in each level. Each level was housed in a single pen of the same size and environment, and carried out according to the routine feeding and management procedures of the pig farm. Free drinking water and food intake, conventional management and breeding, the test period is 90 days.

[0065] Control group: conventional pig feed (ie auxiliary material).

[0066] Treatment group A: 5% fermented purple elephant grass + 95% conventional pig feed (ie auxiliary material).

[0067] The specific treatment method of fermented purple elephant grass is as follows: wash the purple elephant grass and then crush it to a length of 2-3cm. Then, it will be processed by a high-pressure roller machine, and then the treated forage will be quickly put Put it into the ice cellar, add fructo-oligosaccharide and citric acid, stir, stor...

Embodiment 3

[0107] Fermentation of purple elephant grass:

[0108] Experiment 1: The specific treatment method of fermented purple elephant grass is as follows: wash the purple elephant grass and then crush it to a length of 2-3 cm. Then, it will be processed by a high-pressure roller machine, and then the treated forage will be Quickly put it into the ice cellar, add fructo-oligosaccharide and citric acid, stir, store in ice for 24 hours, take it out, immediately use 120 ℃ high fire to defrost while stirring for 3 minutes, then stop the fire, add EM bacteria to mix and build a heap to ferment for 3.5 days, and finally control The water content of purple elephant grass can be 6%.

[0109] Experiment 2: The specific treatment method of fermented purple elephant grass is as follows: wash the purple elephant grass and then crush it to a length of 2-3 cm. Then, it will be processed by a high-pressure roller machine, and then the treated forage will be Quickly put it into the ice cellar, add ...

Abstract

The invention belongs to the technical field of biological feeds, and particularly relates to a feed for improving the diversity of intestinal microorganisms of pigs and an application of the feed, and the feed comprises the following components in percentage by weight: 15%-25% of fermented pennisetum purpureum and 75%-85% of auxiliary materials, and the auxiliary materials comprise the following components in percentage by weight: 30% of corn flour, 25%-35% of soybean meal, 15% of bran, 3% of a mineral premix and 2% of a vitamin premix. Through research, the applicant finds that the natural and nutritional feed can improve the diversity of microorganisms in intestinal tracts of pigs, improve the digestibility of the feed, promote the growth and development of the pigs and reduce the morbidity of the intestinal tracts of the pigs.

Description

【Technical field】 [0001] The invention belongs to the technical field of biological feed, and in particular relates to a feed for improving the diversity of microorganisms in the intestinal tract of pigs and an application thereof. 【Background technique】 [0002] In recent years, with the rapid development of my country's pig industry, the degree of intensification has increased, domestic and foreign livestock and poultry trade has become increasingly frequent, and the chance of disease transmission has increased. Pig farmers generally use feed with additives such as antibiotics, hormones, and chemically synthesized drugs. Long-term use of these feeds will not only easily lead to problems such as drug resistance of pathogenic microorganisms, decline in animal immunity and product quality, but also increase harmful residues in poultry products and the environment, seriously threaten human health. There are complex and diverse microorganisms inhabiting the intestinal tract of p...
