Forecasting the Volume of Beef Consumption in the Russian Market with Various Development Scenarios for Domestic Beef Cattle Breeding: Methods and Results The study develops a methodology and performs the calculations for the medium-term forecasting of beef consumption in Russia under the BAU ("...
Index selection of beef cattle for growth and milk production using computer simulation modelling There was an increase in both birth and yearling weight after 20 years of selection in the small-to-moderate size breed, and there was also an ... K Dzama,M Chimonyo,JO Sanders,... - 《South...
Weaning weights of 442 beef calves (223 male and 219 female), born between 1997 and 2004 from cows of nine breeds (Hungarian Fleckvieh, Hereford, Aberdeen Angus, Red Angus, Lincoln Red, Charolais, Limousin, Blonde d' Aquitaine and Shaver) and maintained in the same conditions on peat-bog...
BEEF cattle performance at constant indoor air temperatures of 13 and 29 °C was compared with performance at 21 °C. Cattle were fed either a 70 or 90%-concentrate ration and had either a 320 or 386 kg-average weight during the tests. Values of feed intake, rate of gain, and feed co...

摘要: Data from the first four cycles of the Germplasm Evaluation Program at the US Meat Animal Research Center (USMARC) were used to investigate genetic relationships between mature weight (MW, n= 37,710), mature weight adjusted for body condition score (AMW, n...
The possibility of selection of beef cattle simultaneously for weight gain and heat tolerance traits is examined. A group of 192 bullocks and heifers were exposed for about 7 hr. to direct sun in a pen. Temperature and respiratory rate were taken before and after heat treatment, the haemoglobi...
