Changes of the testes parameters, carcasses and antlers mass of harvested roe deer (Capreolus capreolus) bucks

Abstract

Abstract:The research was conducted during the hunting season in Poland from May to September 2012 in which materials of 58 roe deer bucks carcass, antler and testis masses were compared. In addition, the size of testes with epididymides was assessed. Significantly enlarged testes masses were observed in May till July (one-way ANOVA and LSD test). In August and September, the testes underwent abrupt involution. According to the literature and the results of this study, the enlargement of the testes which starts from the end of February, indicates that spring time is a preparatory period for the rut. On the other hand, monthly carcass mass fluctuations were not observed. There is, however, a trend suggesting that heavier roe deer individuals can display larger antler mass.

Differentiation in body and testes weight as well as sperm quality of male roe deer from the Lublin Upland in the reproductive season

“…Badania prowadzone w rejonie Wielkopolski w 2012 r. wykazały spadek masy ciała u kozłów pomiędzy majem a wrześniem na poziomie 1,1 kg. Z kolei wzrost masy jąder pomiędzy majem a lipcem wynosił 23,2% (12). Wyniki badań mechanizmów spermatogenezy u samców saren prowadzonych w Niemczech w latach 1998--2000 wykazały 14,6% przyrost masy jąder pomiędzy majem a lipcem oraz 53,5% spadek tej cechy pomiędzy sierpniem a wrześniem (21).…”
