    Foetal Mortality in Dogs and Cats not Related to Spontaneous Abortions
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Max, Andrzej; Jurka, Piotr; Bartyzel, Bartłomiej J.; Grzegrzółka, Beata; Department of Small Animal Diseases with Clinic, Warsaw University of Life Sciences – SGGW, Warsaw, Poland; Department of Morphological Sciences, Warsaw University of Life Sciences – SGGW, Warsaw, Poland; Department of Genetics and Animal Breeding, Warsaw, Poland; Department of Small Animal Diseases with Clinic, Warsaw University of Life Sciences – SGGW, Warsaw, Poland
    Embryonic mortality is associated with full resorption of tissues and fluids from the uterine cavity. Foetal mortality usually results in complete or partial abortion. Sometimes, however, dead fetuses and foetal membranes retain in the uterus till term or even longer. There are only scant information in this area, without epidemiological studies. Each new case widens the knowledge of this condition. The objective of the study was to determine the variations of follow-up of foetal mortality in small animals. On the basis of chosen clinical cases coming from gynaecological and obstetric practice the consequences of foetal mortality without a miscarriage were documented. They were listed as follow: total resorption of the embryo/foetus and foetal membranes, resorption of foetal tissues with remaining of foetal membranes, foetal mummification and foetal maceration.

    Physical Traits of Insemination Boar Ejaculates Depending on the Time from previous Ejaculate Collection
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Adamiak, Agnieszka; Kondracki, Stanisław; Wysokińska, Anna; Bajena, Magdalena; Department of Animal Reproduction and Hygiene, University of Natural Sciences and Humanities, Siedlce, Poland; Department of Animal Reproduction and Hygiene, University of Natural Sciences and Humanities, Siedlce, Poland; Department of Animal Reproduction and Hygiene, University of Natural Sciences and Humanities, Siedlce, Poland; Department of Animal Reproduction and Hygiene, University of Natural Sciences and Humanities, Siedlce, Poland
    The experimental material consisted of 52 805 ejaculates obtained from 335 boars. The ejaculates were collected using the gloved-hand technique. Each ejaculate was assessed using standard methods for the following physical traits: volume, sperm concentration, total number of spermatozoa, and number of insemination doses per ejaculate. The collected materials were grouped according to the criterion of the time from previous collection of ejaculates. The time elapsed from the collection of the previous ejaculate significantly affects the physical traits of ejaculates. Ejaculate volumes, sperm concentrations and the total numbers of spermatozoa in the ejaculates rise along with increasing time intervals from previous ejaculate collections. The numbers of insemination doses prepared from a single ejaculate also rise. The highest increase in the numbers of spermatozoa in the produced ejaculates and in the numbers of insemination doses prepared from the ejaculates is observed after extending the time interval from the previous collection to 4, 5, 6, 7 and 8 and more days. After three or fewer days from the previous collection, high ejaculate collection frequency results in low numbers of spermatozoa in the produced ejaculates and low numbers of insemination doses prepared from the ejaculates.
