The objectives of this study were to investigate the effectiveness of ultrasonography in monitoring ovarian activity by examining follicular growth and regression and studying the correlation between corpus luteum (CL) measurements and plasma progesterone (P4) concentrations, and to compare high-and low-production genetic lines of dairy cows regarding endogenous bovine somatotropin (bST) and milk production effects on follicular wave patterns, size and number of follicles, CL growth and plasma P4 concentrations during the estrous cycle monitored by ultrasound. Seventeen multiparous lactating Holstein cows were divided into two groups, a low-production group (control group, n=9) and a high-production group (select group, n=8). …

LIn this study, the age and season of reproduction, and fecundity of Alburnoide bipunctatus fasciatis caught from Oltu Stream between August 1995 and July 1996 were investigated. Both males and females reached at sexual mature at the age of two. In the Oltu Stream, the Alburnoides bipunctatus fasciatis began to spawn at the end of May when water temperature was 16 °C and the spawning continued to the end of the July when water temperature was 25°C. The mean individual and relative fecundity were determined as 13135±1107 eggs/female and 707700±52129 eggs/female respectively. The fecundity-fork length, fecundity-total weight and fecundity-age relationships …
