RESUMO
1. The quality of gamma irradiated spermatozoa from cockerels was investigated by measuring motility, oxygen consumption and ability to penetrate zona-free hamster ova. 2. Doses of 750 Gy slightly reduced motility and oxygen consumption; however, irradiated spermatozoa penetrated on average 56% (minimum 33%) of hamster ova. 3. The zona-free hamster ova test may be useful for estimating avian sperm quality.

1. Enzyme activities were studied in blood plasma from Rhenish, Italian, Landes and Masseubian geese. 2. Strains used for liver production (Landes, Masseubian) showed higher activities of aspartate transaminase (AST) [EC 2.6.1.1], alanine transaminase (ALT) [EC 2.6.1.2] and fructose aldolase (FRA) [EC 4.1.2.13] while breeds with high egg production (Rhenish, Italian) had higher activities of both alkaline phosphatase (ALP) [EC 3.1.3.1] and acid phosphatase (ACP) [EC 3.1.3.2]
