However, there are many kinds of protease and amylase in digestive enzymes. For example, protease includes pepsin, trypsin and chymotrypsin, etc., which can be divided into acid protease, neutral protease and alkaline protease according to the reaction conditions. Amylase includes α - Amylase, β-amylase, glucoamylase and isoamylase, etc. Different types of proteases and amylases have different

The invention discloses a method for determining a digestive enzyme composition, a compound enzyme preparation and a compound feed for laying hens. According to the method for determining the digestive enzyme combination, through an even design experiment, the digestive enzyme composition with good uniformity is acquired, the influence of the digestive enzyme composition on a substrate is evaluated through bionic digestion, and the digestive enzyme composition with highest dry matter digestibility and highest protein digestibility is an optimal digestive enzyme composition. The most proper digestive enzyme composition obtained through the even design experiment is used for preparing the compound enzyme preparation, the compound enzyme preparation is applied to daily ration of the laying hens so as to improve the reproduction performance of the laying hens, the egg quality is improved, the production cost is lowered, and the economic benefit is improved.
Description
technical field [0001] The invention relates to the field of enzyme preparations, in particular to a method for determining the combination of digestive enzymes, a compound enzyme preparation and a compound feed for laying hens. Background technique [0002] Protease, amylase and lipase are the main endogenous digestive enzymes in animals, which can be secreted by the animal's digestive tract. Due to the imperfect development of the digestive enzyme secretion system, the secretion of digestive enzymes in young animals lags behind. Although adult animals can secrete amylase and protease and lipase, but the utilization rate of nutrients is not optimal. Therefore, if exogenous enzyme preparations are added to the feed, it can not only supplement the deficiency of animal endogenous digestive enzymes, but also improve the activity of endogenous digestive enzymes. Improve the digestion and absorption rate of nutrients. [0003] At present, although there are many researches and p...
