The Effects Of Different Protein On The Performance And Digestibility In Piglets

Choose the same weight, and healthy 27-day-old ternary hybridization (Duroc×Landrace×Youkshire) piglets (28-day-old weanling) 48, were randomly divided into three groups, each with four repeat, repeat every four pigs, and the control group Feeding containing 3% plasma protein powder test diet, the two experimental groups were used with 3% hydrolyzed wheat protein powder (experimental groupⅠ) and 3% hydrolysis of collagen protein powder (experimental groupⅡ) completely replace the plasma protein 3% Powder (lysine maintain consistency), a 28-day official test. The results are as follows:Compared with the control group, the pilot groupⅠandⅡpilot group weaned piglets daily gain were increased by 22.78% (P> 0.05) and 5.00% lower (P> 0.05), respectively, lower than the expected weight of 3.14% (P > 0.05) and increased by 11.52% (P> 0.05); groupⅠcan significantly reduce piglet diarrhea rate (P <0.05), the test group and control groupⅡweaned piglets diarrhea rate not significantly different (P> 0.05). ; piglets intake test groupⅡthere is a downward trend, the groupⅠpiglets intake higher, but the group piglets intake there was no significant difference (P> 0.05).Control group, groupⅠandⅡpilot group weaned piglets apparent digestibility of fat, calcium and phosphorus digestibility between the three treatment there was no significant difference (P> 0.05), the test group and control groupⅠweaned piglets rough protein digestibility no significant difference (P> 0.05).Ⅱtest group and control group, test groupⅠweaned piglets crude protein digestibility significant difference (P <0.01).Ⅰtest group and control group weaned piglets in the serum urea nitrogen indicators there was no significant difference (P> 0.05).Ⅱtest group and control group weaned piglets in the serum urea nitrogen indicators of the difference was significant (P <0.05). GroupⅠand test pilotⅡgroup weaned piglets in the serum urea nitrogen indicators there was no significant difference (P> 0.05). control group, groupⅠandⅡtest of the three processing piglets in the serum alanine aminotransferase, aspartate aminotransferase, total protein, albumin, globulin , alkaline phosphatase, glucose no significant difference (P> 0.05). The results show that: weaning piglet diet of wheat used three percent completely hydrolyzed protein powder instead of 3% plasma protein powder can reduce piglet diarrhea (P <0.05) increase piglet growth performance. Dietary weaned piglets used three percent complete hydrolysis of collagen protein powder instead of 3% plasma protein powder can make piglets basically consistent growth performance, but because of the hydrolysis of collagen protein powder lower prices, it has great value.
