Investigation of Differences in Biochemical and Mineral Composition of Urine between Pregnant and Non-Pregnant Crossbred Dairy Cattle

Dairy farmers have been longing for simple and economical methods of early pregnancy diagnosis. Urine based biochemical and mineral assays could be one of those methods, owing to the ease of sample collection and relatively simple and economical assays involved. However, basic information on changes in urinary composition during early pregnancy in cattle is lacking. This study was designed to e...

Relationships between chemical composition of meat from carcass cuts and the whole carcass in Iranian fattailed sheep as affected by breed and feeding level

To investigate the relationship between chemical composition of meat from the carcass cuts and thewhole carcass, 48 nine-month-old randomly selected ram lambs of Ghezel and Mehraban (24 rams per breed)were used in a trial arranged as a 2 × 2 factorial experiment with two breeds and two feeding levels (high andlow), in a completely randomized design. After 80 days, all animals were slaughtered a...

Leptin as a predictor of carcass composition in beef cattle.

Our objective was to determine if serum concentrations of leptin could be used to predict carcass composition and merit in feedlot finished cattle. Two different groups of crossbred Bos taurus steers and heifers were managed under feedlot conditions near Miles City, MT. The first group consisted of 88 1/2 Red Angus, 1/4 Charolais, and 1/4 Tarentaise composite gene combination steers (CGC) harve...

The Genetic Improvement of Carcass Composition in Beef Cattle

Although carcass trait selection programs have primarily focused on carcass marbling (quality grade), recent changes in the North American beef industry will very likely increase the economic importance of carcass composition (yield grade). Ultrasound technology is a valuable tool in these efforts. This review summarizes recent research pertaining to the role of ultrasound in improving carcass ...
