two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of ecg and subsequent hcg treatment on the reproductive performance of estrus-induced mature lori ewes. in the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (fga) sponges or controlled internal d...

The objective of this study was to evaluate the relationships between milk urea nitrogen (MUN) and other factors and the probability of conception in dairy cows. Data were retrieved from the Lancaster Dairy Herd Improvement Association (DHIA). A total of 713 dairy herds and 10,271 dairy cows were included in the study. Logistic regression was used to determine the within-herd effects of MUN, mi...

the present study seeks to investigate users’ perception and evaluation of the function of designed environments and highlights a deeper understanding of man-environment relationship. the study tries to answer the question: “is there any relationship between the physical features of environment and users’ perception and evaluation of the environment and their spatial behaviors?” such investigat...

A total of 2567 indigenous Greek ewes (Chios, Vlachiki and VlachikixChios breeds) were used to determine the optimum time for insemination, following synchronization of oestrus with MAP-impregnated intravaginal sponges and PMSG during non-breeding season. Within each breed group, the ewes were divided into three subgroups and submitted to a double blind cervical artificial insemination 48 and 6...

The primary aim of this study was to evaluate the performance sorted semen in dairy cattle various breeds Uttarakhand. Total 6382 inseminations were performed different districts. Different factors considered for region, dam breed, parity number, insemination season, bull breed used insemination. Sorted provided by Uttarakhand Livestock Board. and statistical analysis using R version 4.3.1 soft...

The objective of this work was to obtain prevalence estimates of cloudy vaginal mucus in artificially inseminated Holstein cows raised under intense heat, in order to assess the effect of meteorological conditions on its occurrence during estrus and to determine its effect on conception rate. In a first study, an association was established between the occurrence of cloudy vaginal mucus during ...

Th e aim of study was to investigate diff erent models for the evaluation of dairy bulls for male fertility. A dataset containing single insemination records performed on Brown Swiss cows and heifers reared in Eastern Italian Alps was used. Th e outcome variable (successful/ unsuccessful) was analyzed as binary trait. In the fi rst step raw conception rate was computed for each service sire, as...
