“…The over-all mean HOSST -reacted sperm in semen of mongrel dogs was 93.27 ± 0.53 %which was in close accordance with the values reported by Rota et al, (1995) in fresh pooled semen of different breeds, Nair et al, (1999) in mongrel dogs and Veznik et al, (2003) in different breeds of dogs. The findings varied from those reported by Nizanski (2006) in pooled semen and Das (2012) in Labrador semen.…”

“…In the experiment, the maximum value for normospermia obtained was 92% and the average value was 68.6%. The average value of normospermia is somewhat higher in comparison with the normospermia values (57.5%) presented by Veznik et al (2003) in research into the qualitative evaluation of the ejaculates of a group of experimental dogs, and comes closer to the lower limit for the conventional value for normospermia of 70% (Veznik et al, 2000). The value for normospermia is closely derived from the SMI value, just like the other SQA parameters, which are merely a mathematical algorithm of the SMI.…”

38 fresh ejaculates were examined, of which 23 were cryopreserved in three diluents differing in concentration of glycerol and examined after thawing. For each ejaculate we established the concentration, motility, speed of sperm, percentage of live sperm and the morphological image of the ejaculate using routine laboratory diagnosis and SQA parameters at the initial value and after a 120-minute survival test. The values of the parameters found through routine diagnosis and using the SQA device were statistically confronted. From the results it emerges that the device functions on the basis of the turbulence effect of the semen, and therefore on the intensity and character of the moving mass of sperm. From a research perspective, the SQA device is less usable, since the values it provides are not absolutely comparable with the values found through routine laboratory diagnosis. For the practitioner, however, the device may be useful, since the value of the sperm motility index (SMI) indicates the quality of the semen through the close connection of two parameters, concentration and motility. For a more precise assessment of the ejaculate, however, it is necessary to also analyse the remaining parameters of routine laboratory sperm analysis. To be useful in clinical practice for the evaluation of semen, it would be necessary to establish SMI limit values for ejaculates of varying quality.

FILIPČÍK, R., VÁGENKNECHTOVÁ, M., HOŠEK, M., JARINKOVIČOVÁ, L.: The eff ect of the age of dogs on their ejaculate. Acta univ. agric. et silvic. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 3, pp. 45-50 The eff ect of the age of dogs on quantitative and qualitative parameters of the ejaculate was explored. We evaluated 43 dogs; from each dog we collected three samples on three successive days. The dogs were divided into three age categories: 1.5-2 years; 2-3 years; and 3-5 years. The maximum ejaculate volume was collected from dogs of 2-3 years of age; the average volume of ejaculate from 3 collections was 9.1 ml. Microscopic examinations of the ejaculate of this age category of dogs showed that the highest average sperm concentration was 153.62. . In older dogs the ejaculate volume decreased considerably with increasing frequency of collections (8 ml > 5 ml > 2 ml at the 3 rd collection). The amount of motile sperm was the highest in 3 to 5-year-old dogs (76%) and was related with the highest proportion of morphologically normal sperm (66.8%). However in the 3 rd collection of this age category we saw a signifi cant (P < 0.05) increase in the amount of pathologically changed sperm (29.5 < 28.8 < 41.2%), mostly in the structure of the fl agellum. Signifi cant diff erences in the quantity and quality of the ejaculate were discovered not only among the age categories of the dogs but also among the individual collections. dog ejaculate, volume of ejaculate, sperm activity, sperm concentrationThe number of breeders involved in dog breeding is relatively high. However if the owner of the dog is to be a successful breeder his dog must produce a suffi cient amount of good-quality ejaculate capable of fertilisation. The fertility of dogs can be evaluated in two ways. The breeder may wait to see if the bitch will conceive a er mating or if she gives birth to pups. However, such an approach is unprofessional; for reproduction purposes the breeder should use only dogs whose qualitative and quantitative parameters of the ejaculate had been examined. The birth of pups should be taken as the fi nal confi rmation of the fertility of the dog. DEIBEL et al. (1976), DUNPHY (1989), RIGAU et al. (2001) evaluated the basic qualitative parameters of the canine ejaculate. According to KUTZLER (2005) the optimal room temperature for ejaculate collection is 20 °C; the colour, volume, motility, concentration and morphological structure of the ejaculate should be evaluated. GUNAY et al. (2003) evaluated the sperm fraction of the ejaculate of seven German shepherd dogs. On one day the ejaculate was collected twice within 60 minutes. Between the fi rst and the second collection the authors discovered statistically signifi cant (P < 0.05) diff erences in the volume of the ejaculate and sperm concentration, but not in the motility, live sperm count and amount of morphological changes in the sperm structure. SCHAFER et al. (1997) collected canine ejaculates twice a week over a period of 6 months and they discovered si...
