Effects of papaya leaf meal, pineapple skin meal and vitamin D3 supplementation on meat quality of spent layer chicken.

摘要: A study was conducted to evaluate the effects of supplementation vitamin D3, papaya leaf meal (PLM) and pineapple skin (PSM) for 7 days prior slaughter on meat quality spent layer chickens. In Experiment 1, based on Completely Randomized Design, 40 chickens (ISA Brown) were allotted control (n=10), D3 (n=10), papaya (n=10) (n=10) treatments. The combined PLM also examined in this study 2×4 factorial design which, 80 ISA Brown hens were equally divided with (n=40) without D3 (n=40). Ten birds each main treatment group (PLM and PLM D3) then subjected levels 0%, 0.5%, 1% 2% of PLM. Meat analysis (shear force values, drip loss, cooking loss colour) carried out both experiments. have significantly improved tenderness (reduced shear values), loss, cooking colour. However, PSM has resulted no significant effect all analysed traits. Meanwhile, results from 2 demonstrated that inclusion has significantly tenderness, general, the study highlighted potential benefits supplementation for improving chicken.
