"The current study was conducted to find out the effect of using locally manufactured protein concentrate on some productive traits of broilers (weekly body weight rate, weekly weight gain rate, weekly feed consumption rate, food conversion factor) used in the experiment 225 broiler chickens (female) of the age of one day (breed Ross-308) Chicks were distributed randomly into five treatments, with three replications (15 chicks / replicate). The trial parameters were as follows: The first treatment (control T1) provided for the chicks with a diet containing 4% imported protein, the second treatment (T2) for the chicks with a diet containing 2% imported protein + 2% manufactured protein, the third treatment (T3) provided for the chicks with a diet The fourth treatment contains 4% synthetic protein, the fourth treatment (T4) is provided for the chicks with a diet containing 6% manufactured protein and the fifth treatment (T5) using a diet containing 8% manufactured protein. The results showed the absence of significant differences between the trial parameters in all the studied traits, which included live body weight, weight gain, feed consumption rate and feed conversion factor."
This study was conducted to determine the effect of different levels of local concentrated protein extracted from slaughterhouse wastes on some carcasses traits of broiler. A total of 225 female broiler Ross 308 chicks, one day, were used, randomized distributed into five treatments, with three replicates per treatment (15 chicks each replicate). The treatments were as follows: T1; basal diet contains 4% imported protein. T2; basal diet contains 2% imported protein+2% local manufactured protein. T3; basal diet contains 4% local manufactured protein. T4; basal diet contains 6% local manufactured protein. T5; basal diet contains 8% local manufactured protein. The results showed that there were no significant differences between the treatments on the carcass weight, dressing percentage, relative weights of the thigh and breast, as well as the relative weight of the abdominal fat. There were no significant differences among all treatments for the sensory traits of the thigh and breast. In conclusion, the locally manufactured animal protein extraction had no negative significant effect on the characteristics of carcasses and could be used as an efficient alternative to imported protein concentration used in broiler diets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
