In this study, it was aimed to compare
feedlot performance of 26 Holstein and
20 Brown Swiss cattle, (46 in total) grown under Isparta climate
conditions. In this experiment, 10–12 mounts old beef animals were
used with an initial weight of 264 and 273 kg Holstein
and Brown Swiss, respectively. After the experiment which lasted for 7
months mean final weights of Holstein
and Brown Swiss cattle were 535 and 477 kg; mean total weight gains 268
and 209 kg and finally daily liveweight
gains of 1.275 and 0.997 kg, respectively. Final weights, total weight
gains and daily liveweight gains of Holstein
and Brown Swiss cattle and the difference in those parameters between both cattle
were statistically significant (P<0.05). In conclusion, Holstein
breed cattle performed better than Brown Swiss breed cattle in feedlot
beef systems grown under the Mediterranean climate conditions.
