Efficacy of long day photoperiod treatment with respect to age of bucks for stimulation of the “male effect” on does at Mediterranean latitudes
2022, Small Ruminant ResearchCitation Excerpt :However, our group worked with males of the same breed (Gallego-Calvo et al., 2015) observed that a rapid succession of two months of long days (LD) and short days (SD) induced higher values for sperm concentration and total sperm number per ejaculate during the LD treatment. Annual variation in these parameters has been described in the literature for different goat breeds (Karagiannidis et al., 2000; Pérez and Mateos, 1996; Roca et al., 1992). The present results show that at Mediterranean latitudes, the age of the bucks used to induce the "male effect" and the reproductive condition of the bucks were independent because no interaction between them was observed.
Effect of season on sexual behavior, testicular measurements and seminal characteristics in “Beni arouss” North Moroccan bucks
2019, Animal Reproduction ScienceCitation Excerpt :The percentage of normal sperm was greater during the summer (maximum between July and September, being about 83%), while dead sperm values were greater during the winter and spring (26%). This finding is consistent with that of Perez and Mateas (1996) in Verata bucks and similar to those reported for bucks of different breeds (Karagiannidis et al., 2000; Barkawi et al., 2006; Talebi et al., 2009). In these reports, there were the least values for normal sperm in the winter and spring, while there was the greatest proportion of normal spermatozoa in the autumn.
Reproductive seasonality and sperm cryopreservation in the male tufted deer (Elaphodus cephalophus)
2016, TheriogenologyCitation Excerpt :However, there is a lack of fundamental information on the reproductive biology of tufted deer and the impact of season on male reproduction. Seasonal changes in semen and reproductive parameters have previously been reported in many mammalian species, for example, the sheep [14,15], Eld's deer (Rucervus eldi thamin [16]), roe deer (Capreolus capreolus [17]), red deer (Cervus elaphus [18]), pampas deer (Ozotocerus bezoarticus [19]), and American bison (Bison bison bison [20]). Tufted deer typically breed from September through December and fawn in April to July [4].
Relationship between body weight, sexual secondary traits and epididymal semen quality in the Alpine goat
2016, Small Ruminant ResearchCitation Excerpt :Then, delayed growth in body size and testicular mass is expected to lead to reproductive wastage and economic losses. In small-ruminants testicular size and body weight are influenced by several factors, including breed, age, nutrition, and photoperiodic changes (Karagiannidis et al., 2000). Horns are epidermal and bony appendages used by males of many ungulate species for intra-sexual competition during rut (Santiago-Moreno et al., 2007).
