Abstract: This study estimated the relationship between Urea Space (US) and carcass attributes in lambs to derive coefficients for these relationships and functional equations for components of carcass quality and quantity. Twenty-four male Taleshi lambs with an average age of 8 months were used. Lamb live weight was determined using the urea dilution method and two or three days before slaughter, the urea dilution procedure was again used to estimate the chemical composition of the carcass. Subsequently, plasma urea nitrogen was determined and the percentage of urea space to lamb live weight was calculated. After slaughter, the carcasses were butchered and the parts measured. The results showed that the average amount of urea injected was 20.09 cm² and the Blood Urea Nitrogen (BUN) averaged 17.16 and 27.72 mg before and after injection respectively. The average percentage of US to lamb live weight was 18.78%. Correlation coefficients between live weight, empty body weight, hot carcass weight and the weight of different parts of the carcass were high and statistically significant (p < 0.01). The urea space was significantly related to the percentage of protein and ash in the region of the 9th, 10th and 11th ribs (p < 0.05). Using this rib area and US, the development of functional equations between live weight and empty body weight for different parts of the carcass showed that the urea dilution test is a useful tool for predicting the chemical composition of Taleshi lamb carcasses.
