Association between the Melanocortin-4 Receptor (MC4R) Gene Polymorphisms and Growth Trait in Sumba Ongole Cattle
Melanocortin-4 receptor (MC4R) gene has been known as a candidate gene for growth traits in livestock. This research was aimed to identify the polymorphism of MC4R gene and its association with growth traits in Sumba Ongole (SO) cattle. The growth traits data consist of body weight and body size. Eighty four blood samples were collected and used for DNA isolation. The...
متن کاملA single nucleotide polymorphism in NEUROD1 is associated with production traits in Nelore beef cattle.
Feed efficiency and carcass characteristics are late-measured traits. The detection of molecular markers associated with them can help breeding programs to select animals early in life, and to predict breeding values with high accuracy. The objective of this study was to identify polymorphisms in the functional and positional candidate gene NEUROD1 (neurogenic differentiation 1), and investigat...
متن کاملUnderstanding and Improving Beef Cattle Carcass Quality
Interest and questions about the quality of beef are on the rise due to heightened awareness about the marketing of beef, from procurement and processing to consumer acceptance. Belatedly, producers are now beginning to receive information about the quality of the beef they produce. Consolidations among beef marketers have resulted in better communication between marketers and producers on carc...
متن کاملThe relationship between ultrasound measurements and carcass fat thickness and longissimus muscle area in beef cattle.
Five hundred thirty-four steers were evaluated over a 2-yr period to determine the accuracy of ultrasonic estimates of carcass 12th-rib fat thickness (CFAT) and longissimus muscle area (CLMA). Within 5 d before slaughter, steers were ultrasonically measured for 12th-rib fat thickness (UFAT) and longissimus muscle area (ULMA) using an Aloka 500V real-time ultrasound machine equipped with a 17.2-...
متن کاملEvaluation of ultrasonic estimates of carcass fat thickness and longissimus muscle area in beef cattle.
Yearling crossbred feedlot steers (n = 495) and heifers (n = 151) were ultrasonically measured at the 12-13th rib interface 24 h before slaughter to evaluate the accuracy of ultrasonic measurements of fat thickness (BFU) and longissimus muscle area (LMAU) for prediction of actual carcass measures. Isonification was with an Aloka 210DX ultrasound unit equipped with a 12.5-cm, 3.0-MHz, linear arr...
