Crossbreeding trial with Piemontese, German Angus and White-blue Belgian on Fleckvieh cows - 2nd communication: Carcass yield and carcass quality

The beef breeds Piemontese (Pi), German Angus (DA) - red DA (Da(R)) and blm k DA (DA(S)) of 5 bulls each - and White-blue Belgian (WB) were tested on s uitability for commercial crossing with the Bavarian breed Fleckvieh (FV). The generated animals, derived from 10 test-bulls per breed, were tested fo r beef performance in bull and heifer fattening trials. With bulls (n = 330) FV aimed in dressing percentage on average 58,5%, DA w as equal (+0,2%), Pi and WE were superior by +4,4% and +3,8% (both P < 1%), respectively. In these superiorities the smaller hide weights have a part of one-third, but also each of the other offal parts (head, feet, cuts, inn er organe) contributed to the better dressing percentages. These led in car cass weight (FV mean ist 343 kg) to the order Pi +41 kg, WE +31, DAR -18, D A(S) -48 kg (all P < 1%). In net daily gain ranked FV (717 g) before DA(S) -36 g (P < 1%), but was exceeded by Pi +25 g, WE +17 and DA(R) +4 g. In EUR OP-classification (E = 5, P = 1) FV achieved 3,39 points, WE was much bette r tl,Ob p and was followed by Pi +0,47 (both P < 1%), DA(R) -0,13 and DA(S) - 0,08 points. in the area of M, long. dorsi (both P < 1%), and DA was wor se Pi and WE exceeded FV (64,6 cm(2)) by 14,2 and 10,3 cm(2) (both P < 1%), and DA was worse by -2,3 cm(2). Pi and WB also reached the highest lean me at content (+5,9 and +4,5%, both P < 1%), then came FV (69,2%) and DA (-0,7 %). In the heifer fattening trial (n = 245) resultied in net daily gain the ord er (FV 482 g): WE +46 g (P < 1%), DA, +27, DA, +13 und Pi +0 g. Also in EUR OP classification achieved WE +1,14 and especially DA +0,30 a better and Pi +0,35 tall P < 1%) a less good result than with bulls.
