Embodiment 1

[0037] Embodiment 1, the influence of different doses of enzyme bacteria feed additives on weaned piglets

[0038] 1. Experimental design

[0039] The experiment adopts a single-factor randomized block design, selects 240 three-way healthy weaned piglets with an initial body weight of 6.5kg, and randomly divides them into 4 treatments, each treatment has 6 repetitions, and each repetition (column) has 10 pigs. 28d. Amino acid and crude protein levels of dietary ingredients were determined before the experiment started.

[0040] The test groups are as follows:

[0041] Group 1 was fed with basal diet, which was the control group

[0042] The second group added 150 grams of enzyme bacteria feed additive per ton of basal diet, which was a low-dose group

[0043] The third group added 300 grams of enzyme bacteria feed additive per ton of basal diet, which was the middle dose group

[0044] The fourth group added 450 grams of enzyme feed additive per ton of basal diet, which w...

Embodiment 2

[0078] Embodiment 2, the influence of the enzyme bacteria feed additive of different composition ratio on weaned piglets

[0079] 1. Experimental design

[0080] The experiment adopted a single-factor randomized block design, and 240 triple healthy weaned piglets with an initial body weight of 6.7kg were selected and randomly divided into 4 treatments, each treatment had 6 repetitions, and each repetition (column) had 10 pigs. 28d. Amino acid and crude protein levels of dietary ingredients were determined before the experiment started.

[0081] The test groups are as follows:

[0082] Group 1 was fed with basal diet, which was the control group;

[0083] Group 2, Group 3, and Group 4 added 450 grams of enzyme feed additive per ton of basal diet, of which:

[0084] The composition and mass ratio of the second group of enzyme bacteria feed additives are: alkaline protease 30%, acid protease 30%, neutral protease 10%, tryptophan 5%, medium temperature amylase 10%, mannanase 5...

Abstract

The invention discloses an enzyme bacterium feed additive, which comprises the following components by mass percentage: 20-40% of alkaline protease, 10%-30% of acid protease, 5%-15% of neutral protease, 5%-10% of tryptophan, 5%-10% of amylase, 2%-7% of mannase, 3%-8% of clostridium butyricum and 3%-8% of bacillus subtilis. The main raw materials of the enzyme bacterium feed additive provided by the invention are reasonable in composition and proportion, and can reach a synergistic effect, so that the growth performance of weaned piglets can be remarkably improved, the body immunity is enhanced, and the intestinal health is improved.

Description

technical field [0001] The invention relates to the technical field of animal nutrition and feed, in particular to a piglet enzyme bacteria feed additive and its application. Background technique [0002] In modern pig production, the food source of piglets after birth is mainly breast milk. When piglets are weaned, the intestinal function is not fully developed, and the intake of nutrients is converted from liquid breast milk to solid plant-based diets, so it is easy to cause greater food stress in piglets, resulting in damage to the structure and morphology of the digestive tract And the decline of various digestive enzyme activities, such as the decrease in the length of small intestinal villi, the increase in the depth of glands, the weakening of endogenous protease and amylase activity, etc., causing various negative consequences such as diarrhea and growth retardation, which will affect the whole life of pigs in severe cases. The performance of long-term growth perfor...
