The aim of this study was to investigate some spermatological parameters of frozen Brown Swiss bull semen 32 years ago by flow cytometry and to determine how storage time in liquid nitrogen affects in vitro embryo production ratios. For this purpose, early necrotic, necrotic, viable and apoptotic...

This study aims to highlight the cellular and molecular events of atresia in the Bedouin goat ovarian follicles. Ovaries collected from slaughterhouses during breeding and non-breeding seasons were submitted to morphological studies and immunolocalization of active caspase-3. The results showed...

There are 20 years since the title "Artificial Insemination dynamics and prognosis in cattle" was the presented thesis by me as a graduate student. A 20 years period is long enough to find out if the dynamics and the prognosis were true. That time Artificial Insemination was appreciated as a strong ...

After the voluntary waiting period, a chronic uterine infection or a persistent inflammation in the cow may be associated with disruption of the architecture of the endometrial layer and glandular hypersecretion. The aim of our work, the first of this kind in Romania, was to evaluate the efficacy...

Nerve growth factor (NGF), is the first described member of the neurotrophin family and this protein has an approximately 13 kDa molecular weight. Primarily, NGF affects the survival, differentiation and growth of several cells such as stem cell, neutrophil, lymphocyte and monocyte. In addition to...

The productivity of Uruguayan dairy farms has been consistently growing for the last 40 years. This process has implied the adoption of new technologies, which have had significant effects on the production system. The efficiency with which available technologies are used influence output growth....

In this study, we propose a possible way of obtaining reproductive and respiratory syndrome virus (PRRSV) free offspring from genetically valuable lines of Přeštice black-pied boars coming from PRRSV-positive pig breeding herds with the use of artificial insemination (AI). The ejaculates were...

This study investigated changes in the real-time measured levels of milk β-hydroxybutyrate according milk yield, lactation number and status of reproduction in dairy cows. A total of 378 cows were selected. According to their reproductive status the cows were classified as belonging to the...

The present work aimed to describe some important concepts regarding the reproductive physiology of pharmacological control of the estrous cycle, presenting different protocols for IATF. IATF has become one of the leading reproductive biotechnologies of economic importance in cattle production...

There are a lot of factors that influence bull semen quality used on commercial artificial insemination and makes fertility prediction difficult. The aim of the present study was to analyze in vitro quality of Flackvieh-Simmental bulls' parameters including different type of motility (computer...
