Embodiment 1

[0021] Embodiment 1 low temperature alpha-amylase action effect is better than medium temperature alpha-amylase

[0022]

[0023] Note: 108 Dudu long suckling piglets with a body weight of about 9.5kg were selected for the test, and the random block group was divided into 3 treatments, each treatment had 6 repetitions, and each repetition had 6 pigs, the difference between the groups was not significant (P>0.05) . The pre-test period is 7 days, and the test period is 18 days.

[0024] Control group - fed suckling piglet feed

[0025] Treatment group 1 - feeding suckling piglet feed + low temperature α-amylase (45g / t)

[0026] Treatment group 2 - feeding suckling piglet feed + medium temperature α-amylase (45g / t)

[0027] The experimental results showed that treatment group 1, that is, adding low-temperature α-amylase group, improved the performance of suckling piglets better than adding medium-temperature α-amylase group. Although they are all amylases, their enzymatic ...

Embodiment 2

[0028] Example 2 Interaction between low temperature α-amylase and glucoamylase

[0029]

[0030] Note: 144 Dudu long-suckling piglets weighing about 9.5kg were selected for the test, and the random block group was divided into 4 treatments, each treatment had 6 repetitions, and each repetition had 6 pigs, the difference between the groups was not significant (P>0.05) . The pre-test period is 7 days, and the test period is 18 days.

[0031] Control group - fed suckling piglet feed

[0032] Treatment group 1 - feeding piglet feed + low temperature α-amylase and glucoamylase compound (45g / t)

[0033] Treatment group 2 - feeding piglet feed + low temperature α-amylase (45g / t)

[0034] Treatment group 3 - feeding piglet feed + glucoamylase (45g / t)

[0035] The experimental results showed that the production performance of treatment group 1, which added low-temperature α-amylase and glucoamylase compound, was significantly better than treatment group 2, which added low-tempe...

Embodiment 3

[0037] The xylanase effect of embodiment 3 Trichoderma reesei liquid fermentation is better than Pichia pastoris liquid fermentation xylanase

[0038]

[0039] Note: 180 Dudu long suckling piglets with a body weight of about 9.5kg were selected for the test, and the random block group was divided into 5 treatments, each treatment had 6 repetitions, and each treatment had 6 pigs, the difference between the groups was not significant (P>0.05) . The pre-test period is 7 days, and the test period is 18 days.

[0040] Control group - fed suckling piglet feed

[0041] Treatment group 1 - feeding suckling piglet feed + xylanase (10g / t) of Trichoderma reesei liquid fermentation

[0042] Treatment group 2—feed for suckling piglets + xylanase from liquid fermentation of Pichia pastoris (10g / t)

[0043] Treatment group 3—feed for suckling piglets + compound enzyme in formula 1 except xylanase (10g / t)

[0044] Treatment group 4—feed for suckling piglets + formula 1 compound enzyme ...

Abstract

The invention relates to the field of feed additives, in particular to a complex enzyme capable of improving production properties of suckling piglets and an application of the complex enzyme. The complex enzyme comprises 60-80wt% of endogenous enzymes and 20-40wt% of non-starch polysaccharides enzymes, wherein the endogenous enzymes comprise low-temperature alpha-amylase, glucamylase, acid protease, neutral protease and alkali protease; and the non-starch polysaccharides enzymes comprise xylanase obtained through trichoderma reesei liquid fermentation, mannase obtained through aspergillus niger solid fermentation, beta-glucanase, cellulase and pectinase. The problem of low digestion and utilization rate of a feed, caused by imperfect digestive enzymes of the suckling piglets at the stagecan be effectively solved, and the raising cost can be saved.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a compound enzyme for improving the production performance of suckling piglets and an application thereof. Background technique [0002] Before the age of 40 days, the pepsin activity of piglets is extremely low, which is gastric acid-dependent; the activity of digestive enzymes is not good, and many nutrients cannot be digested and completely excreted from the body; The intestinal tract is relatively weak, and it is difficult to resist the stimulation of food allergens; too much protein intake causes the intestinal tract to be overburdened and some diseases are rampant; immunity and stress are frequent, and it is urgent to improve the basic immunity of the intestinal tract. [0003] Piglet rations have several main features: starch is the main source of energy, with the highest content; protein is the second largest content, and is generally mainly plant-based, which does not match...
