Embodiment 1
[0036] A single factor design was used to select 240 weaned piglets (half male and half female) at the age of 24 days who were healthy and close to each other in body weight for the feeding experiment. The 240 piglets were randomly divided into two groups, which were used as the experimental group and the control group respectively. groups, 120 piglets in each group. Among them, the control group was fed with common corn-based piglet feed, and the test group was fed with common corn-based piglet feed with a mass fraction of 0.5% premix. The pre-feeding period was 4 days and the test period was 21 days. During the experiment, the feeding management procedures and immunization procedures were carried out according to the conventional commercial pig feeding management manual.
[0037] The premix added by the test group includes the following components and parts by weight: 6 parts of lipase, 11 parts of lysophospholipid, 9 parts of bile acid, 11 parts of carbohydrate compound enz...
Embodiment 2
[0050] A piglet premix for improving energy digestibility, the premix comprising the following components and contents in parts by weight: 4 parts of lipase, 15 parts of lysophospholipid, 6 parts of bile acid, 15 parts of carbohydrate complex enzyme, phytase 5 parts, 20 parts glutamine and 5 parts vehicle.
[0051] Wherein, the carbohydrate complex enzyme includes amylase, cellulase, pectinase and β-glucanase; the phytase is a high-temperature-resistant phytase; and the carrier is bran.
[0052] The preparation method of this piglet premix specifically comprises the following steps:
[0053] 1) The carrier is divided into two parts, respectively carrier A and carrier B, and the mass ratio of carrier A to carrier B is 2:1;
[0054] 2) adding lysophospholipid, bile acid and glutamine to carrier A respectively, and stirring evenly to obtain mixture A;
[0055] 3) respectively adding lipase, carbohydrate complex enzyme and phytase into carrier B, and stirring evenly to obtain mi...
Embodiment 3
[0059] A piglet premix for improving energy digestibility, the premix comprising the following components and contents in parts by weight: 8 parts of lipase, 8 parts of lysophospholipid, 12 parts of bile acid, 8 parts of carbohydrate complex enzyme, phytase 10 parts, glutamine 10 parts and vehicle 50 parts.
[0060] Wherein, the carbohydrate complex enzyme includes maltase, protease, glucose oxidase and mannanase; the phytase is high temperature resistant phytase; the carrier is soybean meal powder.
[0061] The preparation method of this piglet premix specifically comprises the following steps:
[0062] 1) The carrier is divided into two parts, respectively carrier A and carrier B, and the mass ratio of carrier A to carrier B is 2:4;
[0063] 2) adding lysophospholipid, bile acid and glutamine to carrier A respectively, and stirring evenly to obtain mixture A;
[0064] 3) respectively adding lipase, carbohydrate complex enzyme and phytase into carrier B, and stirring evenly...
