Can body weight be considered to estimate the gizzard meat yield in meat chickens?

Application. Body weight in meat chickens could be considered for the estimation of gizzard weight, providing a pre-processing estimate of gizzard meat yield for poultry processors. Introduction. Gizzard is a nutritionally important tissue: a one-cup serving of cooked chicken gizzards comprises 223 calories, 44 grams of protein and 4 grams of fat. Gizzard is also an excellent source of iron and zinc (Alfaro, 2020). Therefore, estimation of gizzard weight is useful for processors needing to sell gizzard meat. A linear relationship between body weight and gizzard length and width is reported by Mobini (2010). However, there is lack of information on association of gizzard weight and body weights in broiler chickens. The main objective of the study was to propose and develop a simple but robust model to estimate the gizzard weight through body weight in Ross 308 meat chickens. Materials and Methods. The study was ethically approved by the...
