SUMMARY Trials to compare mating ratios are important for optimizing the breeding efficiency of broiler breeder flocks. However, the parameter that is normally used for such comparisons—‘fertility’ of all eggs or a sample of eggs from the flock

1. The frequency distribution of points of sperm hydrolysis (or holes) produced per unit area of the inner perivitelline layer was examined in samples of approximately 60 laid eggs, taken on the same day from each of 19 flocks of broiler breeder hens

The inner perivitelline layer, separated from laid chicken eggs, was investigated as readily available material for studying the spermatozoa-egg interaction in vitro. This layer was found to have a similar response to hydrolysis by spermatozoa as the

Computer-Aided Design and Manufacture (CADCAM) learning is generally assessed by project-type assignment work necessarily undertaken over a prolonged period of time. This paper promotes the method of assessing the users of CADCAM by timed examination

1. The breeding efficiency of broiler flocks was assessed by estimating the numbers of spermatozoa trapped in a 5.5 mm2 area of the perivitelline layer of laid eggs. 2. In samples of approximately 60 eggs taken from flocks on the same day, the number

Semen quality in captive-bred Houbara bustards, Chlamydotis undulata undulata, was assessed during three consecutive breeding seasons. In any one season, sperm quality, in terms of the proportion of eosin-permeable spermatozoa and of spermatozoa with

1. The frequency distribution of points of hydrolysis produced by spermatozoa in the perivitelline layer from directly over the germinal disc was examined in 60 samples of 60 eggs from commercial broiler breeder flocks. 2. Typically, these distributi

Semen collected from 3-year-old male Houbara bustards contained large proportions (6-40%) of spermatozoa with large nuclei. In these spermatozoa, the length of the nucleus was up to twice the mean length of the nucleus in normal spermatozoa. The leng
