  A total of ninety-six Shaver 579 pullets were fed on isocaloric and isonitrogenous diet with vitamin-mineral premixes, Supramixes Layer, Acimix Super-L and Adivit-L and without premix (control) in the age duration from 25 to 40 weeks to evaluate the efficacy of different commercial premixes. Daily feed intake and body weight gain of the pullets did not differ significantly (P>0.05). Hen day egg production of different treatments differed significantly (P< 0.01). Higher and statistically similar egg production was obtained in Supramix layer (75.4%) and Acimix Super-L (74.12%) treatment. The lowest (62.5%) and statistically similar (65.99%) egg production occurred in control and Adivit-L treatment respectively. Egg weight of the treatments differed significantly (P< 0.01). The highest (57.15g) and statistically similar (56.57g) egg weight was observed in supramix Layer and Acimix Super-L group respectively. The highest egg mass output of Supramix Layer (42.98) differed significantly (P< 0.01) from the control (33.98). Significant (P< 0.01) difference was observed in the FCR value of Supramix Layer (2.68) and control (3.43) group. Broken egg percent of the treatments differed significantly (P< 0.01). High broken egg (4.11%) was observed in control group. No significant (P>0.05) differences were observed in livability. The observation of the results showed that use of commercial vitamin-mineral premix to supplement the diet of caged laying pullets is inevitable to maintain desirable production level. But the efficacy of all commercial premixes was not equal. The quality of marketed premixes is not uniform which is revealed in terms of performance test in the study.

  A total of 144 ISA-i757 broiler chicks were fed on mash, pellet and crumble diet in the age duration of 21 to 56 days to compare the performance of broiler on different dietary groups. All the forms of feed were of identical composition as well as same environment and management were provided for all the treatments. The body weight of birds fed on mash, pellet and crumble group from 4th to 8th weeks of age differed significantly (P< 0.01). The highest, intermediate and the lowest body weight were observed for crumble, pellet and mash group respectively. The body weight gain also highest in crumble group (P< 0.01). Feed consumption of the 3 treatments differed significantly (P< 0.01). Crumble group showed high trend of feed consumption. Higher FCR value (P< 0.01) was observed for mash group, which indicated low feed conversion efficiency. On the other hand crumble and pellet group showed better fed conversion efficiency. Significantly high (P< 0.01) performance index and production number were observed for crumble group. Survivability percent of all treatments did not differ significantly (P>0.01). Total cost of production was significantly (P< 0.01) less for crumble and this was statistically similar with pellet group. The results of this experiment give an impression that crumble form of feed is better than mash and pellet form for the production of commercial broiler for the age duration of 21 to 56 days.
