Title

EFFECTS OF POULTRY BY-PRODUCT MEAL ON PERFORMANCE, EGG QUALITY AND BLOOD PARAMETERS OF COMMERCIAL LAYING HENS AT THE 42-52 WEEKS OF AGE

Pages

  29-42

Abstract

 Present study was conducted to study the effects of POULTRY BY-PRODUCT MEAL (PBPM) on performance of commercial LAYING HENs.160 Hy–Line W-36 hens at the age of 42 wk were selected and housed in laying cages with four hens per cage. Five experimental diets containing 0%, 2%, 4%, 6% and 8% PBPM were formulated according to nutrient requirement recommendations of Hy-Line W-36 strain and were fed during 42-52 wk of age. The trial was conducted using completely randomized design with five experimental diets as treatments and four replications for each treatment. Tow cages served as one replication. Egg weight, egg production percent, egg mass and feed intake were significantly decreased as the level of PBPM was increased in the diets (P<0.05). Feed conversion ratio was significantly increased by increasing the level of PBPM in the diets (P<0.05). The highest Haugh unit (80.38) and yolk color (7.18) were observed in diet containing 8 percent PBPM (P<0.05).Increasing level of PBPM in the diets had no significant effect on albumen and yolk percentage. The effect of different levels of PBPM on serum glucose, cholesterol, triglyceride, calcium, phosphorous, LDL and HDL concentration were not significant. The results suggested that this product could be used up to 2% in layer diets at the 42-52 weeks of age without any detrimental effects on laying performance, EGG QUALITY and blood parameters.
