Effect of hydroponic barley fodder on growth performance, carcass yield and carcass quality of cobb 500 broilers

This study was conducted to evaluate the effect of hydroponic barley fodder supplementation on growth performance, carcass yield and carcass quality of Cobb 500 broilers. An accustomed proper feeding and brooding have been given to the chicks for up to three weeks of age. After three weeks, 144 three-week-old birds were randomly assigned to four treatments and replicated three times with 12 chicks per replication in a completely randomized design. Treatments were arranged as follows; T1: Home formulated Broiler diet (control group), T2: Home formulated Broiler diet +3.5 % hydroponic barley fodder, T3: Home formulated Broiler diet +7 % hydroponic barley fodder, and T4: Home formulated Broiler diet +10.5 % hydroponic barley fodder. The proximate analysis revealed that, hydroponic barley fodder contained 15.63 % crude protein, 10.6 crude fiber, and 4.04 ether extract. Increasing the level of hydroponic barley fodder was associated with an improvement of both growth performance and weight of carcass components of Cobb 500 broilers. Higher average daily feed intake (112.72 g/bird), daily body weight gain (56.37 g/bird), total body weight gain (1579.39 g/4 weeks) were obtained from T4 (home formulated feed +10.5 % HBF). Similarly, higher feed conversion efficiency (1.99 g of feed/g of weight gain) was recorded in T4. Hydroponic barley fodder had no significant (P > 0.05) effect on the mortality rate and carcass quality of broiler chickens. Economically, the highest net return was obtained from birds fed on T4 (Home formulated Broiler diet +10.5 % hydroponic barley fodder). In conclusion, supplementing hydroponic barley fodder up to 10.5 % improves carcass characteristics and result higher net income compared to other treatments. The current study recommended that further investigation like inclusion and substitution trial should be conducted to determine whether hydroponic barley fodder can replace expensive poultry ration ingredients.
