Application Of Red Pepper And Pine Powder Processed By Pressure-shear Induced Chemical Transitions In Laying Hens

There are more and more requirements on the animal food safety with the developing of people life level.But the abuse of the antibiotic additives in the diet was potential menace to the human health.And the natural plant was popular with the people because of the plant rich resources,without drug resistance,less toxic and side effects,free of harmful residues.Green and rich in carotenoid eggs production was the major target of this research.The experiments were planned to study the effects of red pepper powder or pine powder processed by Pressure-shear Induced Chemical Transitions(PICT) on the egg production performance,egg quality and serum biochemical parameters of laying hens.Six hundred of Hyline Brown laying hens of 30 weeks old were randomly divided into 20 groups.Each group was assigned 3 replications and 10 layers per replication.The control group(â… ) was fed with the basic diet.1) The application of red pepper powder processed by PICT in laying hensThe groupâ… ,â…¡,â…¢,â…£,â…¤,â…¥andâ…¦were fed diet supplement with 0.8%red pepper powder,0.8%red pepper superfine powder,0.8%superfine powder with Na₂CO₃ mixed and 0.8%,0.5%or 0.3%red pepper powder processed by PICT,respectively;the group L₁,L₂,L₃,L₄,L₅,L₆ and G contained 30,60,120,240,480 or 960g t^-1 of Red Chillies or 30 g t-1 of Carophyll Red with basic diet,respectively,were designed for the active-controlled groups.The period was divided into two phases including 15 days of experiment and 8 days of observing experiment with the basic diet.The results revealed that red pepper processed by PICT of the diet of laying hens could increase the average egg weight and egg yolk color. Compared with the control group(â… ),the egg weight increased by 8.48%(p＜0.05) and the yolk color were darkened from the 7 to the 13(p＜0.05).No significant difference in the other egg performance and serum biochemical parameters was observed among the treatments (p＞0.05).It was better to add 0.5%red pepper processed by PICT to the diet.The Red Chillies or Carophyll Red improved the egg yolk color significantly while they did not effect the production performance,egg quality and serum biochemical parameters of the laying hens (p＞0.05).2) The application of pine powder processed by PICT in laying hens The pine powder groups were fed diet supplement with 3%pine powder,3%pine superfine powder,3%superfine powder with HP-β-CD mixed and 3%,2%or 1%pine powder processed by PICT,respectively.The period was divided into two phases including 7 days of pre-experiment and 23 days of experiment.The results revealed that pine powder processed by PICT of the diet of laying hens could increase the average egg weight and egg yolk colour.Compared with the control group(â… ),the egg weight increased by 13.16% (p＜0.05) and the egg yolk color was darkened from the 7 to the 8(p＜0.05).No significant difference in the other egg performance and serum biochemical parameters.It was better to add 0.5%pine powder processed by PICT to the diet.In all,there was significant increased on performance and egg quality of the laying hens after adding the red pepper powder and pine powder processed by PICT in basal diet,while feed conversion efficiency and the immunity in carotenoid was improved to some extent.
