title: [Lysozyme activity in the milk of sucking mares during lactation].
abstract: It was the aim of this project to investigate the changes of the lysozyme activity in the milk of mares during the lactation period. Further on the influence of race, date of conception and foaling, age and number of lactations on the lysozyme activities in milk was analysed. Milk samples were collected from 44 mares (trotters, warmblood, quarter horses) from eight farms between the 1st and 90th day p. p. The activity of the lysozyme was measured by a turbidometric method. Summarizing the following results are obtained: Lysozyme activities in mare milk of the 1st and 3rd day p. p. were higher than in mature milk. On average the highest lysozyme activity (Xa = 113.600 +/- 25.171 U/ml) was measured on the 3rd day p. p. Until the 9th day p. p. the activity decreased about 25%, afterwards there was only a slight decrease. The lowest activity (Xa = 57.509 +/- 14.606 U/ml) was measured at the 83rd day p. p. The influence of race and conception time proved to be statistically significant resp. highly significant.
