[ 1 ] - The evaluation of udder health status in Holstein dairy farms located in Qom province

BACKGROUND:Mastitis is the most economically importantdisease in dairy industry worldwide. Bulk tank milk (BTM)analysis has been suggested for monitoring the udder healthstatus at herd level. OBJECTIVES: A cross-sectional study wasconducted to evaluate udder health status in 15 Holstein dairyfarms located in Qom province. METHODS: Bulk tank somaticcell count (BTMSCC) was analyzed using opto-flu...

[ 2 ] - Reduced anti-Müllerian hormone (AMH) in mares with hemorrhagic anovulatory follicles

Anti-Müllerian hormone (AMH) has been observed to decrease with the development of hemorrhagic anovulatory follicles (HAFs) in mares. Two studies were conducted to evaluate AMH concentration in mares with HAFs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of AMH with the development of luteinised unruptured follicles (LUFs). In study 1, AMH and progesterone were e...

[ 3 ] - Evaluation of therapeutic effects of a 5-day intrauterine infusion of 6% Eucalyptus globulus oil solution on mares with experimentally induced endometritis with Streptococcus zooepidemicus

Endometritis is one of the major causes of infertility in mares. The present study was conducted to evaluate intrauterine infusion of Eucalyptus globulus oil as treatment for mares with experimentally induced endometritis. Mares (n=8) were synchronized using two injections of PGF2α (10 mg) 14 days apart. All mares were inoculated with a live culture of 5 × 106 CFU S. zooepidemicus in the dioest...

[ 4 ] - Effect of extracellular matrix on testosterone production during in vitro culture of bovine testicular cells

Testosterone is believed to play a significant role in spermatogenesis, but its contribution to the process of spermatogenesis is not completely understood. Given that extracellular matrix (ECM) facilitates differentiation of spermatogonial stem cells (SSCs) during culture, the present study was conducted to elucidate whether testosterone contribute to the permissive effect of ECM on SSCs diffe...

[ 5 ] - Enhancement in colonization of bovine spermatogonial stem cells following addition of knock-out serum replacement to culture medium

Enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (SSCs) transplantation. Knock-out serum replacement (KSR) has been reported to enhance the proliferation of murine SSCs and human embryonic stem cells. The aim of the present study was to investigate the effect of KSR versus fetal bovine serum (FBS) ...

[ 6 ] - Effects of diets supplemented by fish oil on sex ratio of pups in bitch

The present study was conducted to evaluate the effect of fish oil supplementation prior to mating on secondary sex ratio of pups (the proportion of males at birth) in bitches. Sixty five bitches (German Shepherd, n = 35; Husky, n = 30) were enrolled in the study. Bitches (140-150 days post-estrus) were given 2% per dry matter intake palm oil and fish oil in the control (n = 33) and treatment (...

[ 7 ] - The role of fibroblast growth factor receptor 2 (FGFR2) in differentiation of bovine spermatogonial stem cells (SSCs)

The receptors 1 and 2 of fibroblast growth factor (FGFR1 and FGFR2, respectively) have been observed in all types of testicular cells. Culture on extracellular matrix (ECM) has been observed to lead to initiation of differentiation in spermatogonial stem cells (SSCs). The present study was carried out to investigate whether FGFR1 and FGFR2 play a role in SSCs differentiation. Following isolatio...

[ 8 ] - Androgen receptor blockade using flutamide skewed sex ratio of litters in mice

Maternal testosterone has been indicated to affect sex ratio of offspring. The present study was conducted to elucidate the role of androgen receptor in this regard by blockade of androgen receptor using flutamide in female mice. Mice were randomly assigned to two experimental groups. Mice in the control (n = 20) and treatment (n = 20) groups received 8 IU equine chorionic gonadotropin (eCG) fo...

[ 9 ] - بررسی اثرات ضددردی و جانبی انفوزیون همزمان لیدوکایین و زایلازین در اسب

زمینه مطالعه؛ انتخاب داروی ضد درد مناسب در اسب یک چالش بزرگ در طب اسب به حساب می‌آید. تعداد داروهای ضد درد در اسب محدود است و اغلب آن‌ها اثرات جانبی ناخواسته‌ای دارند که استفاده از آن‌ها را محدود می‌نماید هدف؛ معرفی ترکیبی که اثرات ضد دردی مطلوب به همراه حداقل اثرات جانبی را داشته باشد. روش کار؛ در این مطالعه 6 رأس اسب سالم در دو گروه کنترل و درمان مورد مطالعه قرار گرفتند در گروه کنترل نرمال سا...
