Progeny testing of AI boars in 1992 was very successful

, : Progeny testing of AI boars in 1992 was very successful. KB Mitteilungen 31(1): 46-47

For 289 progeny groups from Swiss Edelschwein boars tested in 1992, daily gain on test averaged 916 g vs. 884 g for 91 Swiss Improved Landrace progeny groups, food consumption per kg gain averaged 2.46 kg vs. 2.61, percentage of prime carcass cuts 54.9 vs. 53.8, carcass quality score 3.8 vs. 3.8, the percentage of intramuscular fat 1.3 vs. 1.1, and boar breeding value index was 100 vs. 99.
