Effect of Pawpaw (Carica papaya) Seed Diets on Production Performance of Boiler Breeders and Hatching Parameter
Abstract
Background and Objective: A major challenge in broiler breeder management is the nutritional requirement to optimize their reproductive performance. Additional levels of phytobiotics in the diet could improve broiler breeder reproductive performance and hatchability. The present study was conducted to evaluate the effects of Pawpaw seed meal in the diets on reproductive performance and egg hatching of Sasso breeder hens. Materials and Methods: Ninety hens and 12 males of Sasso strain were divided at random, into two groups of 45 hens and 6 cocks each. During the trial, feed intake, body weight, egg weight and egg component weights were recorded weekly. Blood samples were collected at 35 and 41 weeks of age to determine some serum parameter. At 31 and 43 week of age, respectively, 490 and 440, set table eggs were collected during 7 days and stored at 15°C and 70% relative humidity. Prior to setting for incubation, eggs were numbered, weighed, assigned into 4 replicates of 50 eggs in each dietary treatments. Results: Results indicated that breeders of Carica papaya seed diets group had heavier eggs (p<0.05) with higher ratio of albumen weight to egg weight (p<0.01) and feed conversion ratio than those of control group (p<0.05). In addition, day-old chicks from eggs of Carica papaya seed diet group were heavier (p<0.05) than those from eggs of control diet group. Conclusion: It was concluded that Carica papaya seed diets during lay period improved performance parameters and day-old chick weight. However, Carica papaya seed diets negatively influenced hatchability rate, ASAT, ALAT and Uric acid concentration.
