چکیده مقاله:
Current study was conducted in the poultry field of the Department of Animal Production, Faculty of Agriculture, University of Kufa to determine the effect of adding sheep and cows rumen liquids to drinking water as a biological promoter and its effects on productive traits and economic indicator of meat broiler. ۲۴۰ of one-day-old meat chicks (c.v Ross ۳۰۸), sex unspecified with initial weight of ۴۵ g were used. Chicks were raised for ۳۵ days in closed hall divided into coops, ۳ m۲ in surface area for each and distributed randomly in four treatments with three replicates for each treatment (۲۰ chicks for each replicate). Treatments were as follows: T۱ (control without adding rumen liquid), T۲ (adding ۱ mL L-۱ sheep rumen liquid to drinking water), T۳ (adding ۱ mL L-۱ cow’s rumen liquid to drinking water) and T۴ (adding ۰.۵ mL L-۱ sheep and cow rumen liquids to drinking water). Chicks were fed with rennet (starter) from the first day for ۱۰ days and fed with grower from the ۱۱th to ۲۴th days then with finisher diet from ۲۵th to ۳۵th days. Results showed that adding sheep and cow rumen liquids together to the diet of broiler was gave the best outcome for the final live body weight, final weight gain, improving feed conversion rate and economic indicator. Most studied traits were not significantly differ when adding cow’s rumen liquid to drinking water alone, also all experimental treatments were not significantly differ for the total consumed feed and dressing percentage. Adding the sheep and cow rumen liquids together had positive impact on some productive traits and enhanced the economic indicator of meat broiler.
