Embodiment 1

[0032] Example 1: Verification of feeding effect of compound enzyme preparation degrading straw

[0033] 1. Test material

[0034] 1.1 Experimental animals: 400 Dorper×Small-tailed Han sheep hybrid F1 male lambs (uncastrated) with a body weight of (26.95±0.91kg), similar age, and good body condition were selected as experimental animals. The experimental sheep were fed twice a day at 5:00 and 17:00, respectively, and had free access to water. The feeding amount is adjusted according to the feed intake of the sheep on the previous day to ensure that there is about 10% leftover material in the feeding trough.

[0035] 1.2 Experimental diet: self-prepared, premixed feed provided by Beijing Precision Animal Nutrition Research Center. According to the nutritional requirements of mutton sheep in NRC (2007), corn stalks were used as roughage to formulate TMR diets with a fine-to-coarse ratio of 4:6 and 5:5. The official test period is 66 days. The ratio of fine grain to coarse gra...

Abstract

The invention discloses a straw type dietary compound enzyme preparation. The enzyme preparation comprises components in parts by weight as follows: 55-110 parts of cellulose, 55-105 parts of beta-dextranase, 45-100 parts of xylanase, 45-110 parts of pectinase and 70-140 parts of laccase. According to the compound enzyme preparation, lignin, cellulose and hemicellulose of straw are degraded effectively after the straw is processed, surrounding of other nutrients by lignocellulose is broken through, so that the straw nutrient digestibility is improved and the feed conversion rate is increased. The compound enzyme preparation is convenient to use, and the animal growth rate, the economic benefit and the social benefit can be increased effectively.

Description

technical field [0001] The invention relates to the field of processing and utilization of ruminant roughage in the feed industry, in particular to a straw-type dietary compound enzyme preparation and application thereof. Background technique [0002] my country is very rich in crop straw resources. In 2013, the total output of crop straw in the country was 964 million tons, accounting for 30% of the world's total straw production, ranking first in the world, and the collectable and usable amount was 819 million tons. Crop straw is also one of the most abundant feed resources, but less than 31% is used for raising livestock, which still has great development potential. Straw has the characteristics of high fiber and low quality, poor palatability and low utilization rate. Monogastric animals generally cannot use straw, and only a small part can be used to feed ruminants, and the digestibility of ruminants to straw is only 20%-30%. Therefore, it is of great significance to ...
