Material type: materialTypeLabelBookPublisher: 2000Subject(s): Department of Animal NutritionDDC classification: 0632,T Dissertation note: Protein as a second major factor in formulatiQn of poultry rations after energy. It is supplied by animal and vegetable sources. Animal protein supplement are superior in quality due to its more balanced amino acid profile but are costly. While vegetable proteins are cheaper but lacking in some amino acid and have some antiS nutritional factor. The animal protein supplements available in Pakistan are blood, fish, meat and PBPM. PBPM is abundantly available in Pakistan and it is prepared by using chicken feet, heads, viscera, feather skin and blood. And processing varies from organization to organization. PBPM is prepared by different organization such as M. Artal, BeBeJan and Kakasian. PBPM has low cost and its CP and ME are comparable to fish meal, but it is low in lysine and methionine. Our present study was to compare the effect of processing of PBPM manufactured by BeBeJan and Kakasian feed industry. Both have different composition and different processing method of PBPM as blood was included in BeBeJan PBPM but it was absent in Kakasian. The objective of study was to evaluate nutritional profile and quality of commercially available PBPM, the effect of processing on performance of broiler chicks. 240 day old Hubbard chicks were purchased from the local marked and were divided into 8 groups from A to H which were again subdivided into 3 replicates of 10 birds each. Eight experimental starter and 8 experimental finisher rations of A, B, C, 13 and E, F, G, H were prepared. A and E were the control group while B, C and D having 3, 6, 9% PBPM of BeBeJan and F, G, H having 3, 6, 9% PBPM of Kakasian were formulated and starter rations were fed to chicks upto 28 days of age while finisher was provided from 29 to 42 day of age. The feed was supplied to the chicks reared in cages at College of Veterinary Sciences, Lahore. The proximate analysis of the rations was done. And the parameters studied were weekly weight gain, feed consumption, FCR. At the end of the experiment three birds from each group were slaughtered to observe the dressing percentage and weight of internal organs. The economics of the experiment was also calculated. The pepsin digestability of both the organizations PBPM was also recorded. The data thus collected was subjected to statistical analysis. The results indicated that in BeBeJan group there was a significant weight gain in control group A (O%PBPM) while in Kakasian it was significant in F group having 3% PBPM. While comparing both organization PBPM it was observed that F&H rations having Kakasian PBPM 3% and 9% were better than B and D ration having BeBeJan PBPM 3 and 9% regarding weight gain while FOR of BeBeJan it was better in control group A (0% PBPM) while in Kakasian it was better in F group having 3% PBPM. While comparing both organations it was observed that Kakasian PBPM showed better FCR than that of BeBeJan. And it might be due to processing and no adultration of blood in PBPM by Kakasian, while BeBeJan PBPM contained blood. The dressing percentage of control group was better than treated group while comapring both organizations PBPM was non-significant difference among the groups.
