The present study was conducted to see the effect of non-specific genital infections and ovulatory disturbances on clinical signs of oestrusnamely oestrus duration, tonicity of uterus, relaxation of cervix and persistence of follicle. The mean values of oestrus duration, tonicity of uterus and relaxation of cervix varied significantly (P
This study aimed to evaluate protection induced by the vaccine candidate B. ovis ΔabcBA against experimental challenge with wild type B. ovis in rams. Rams were subcutaneously immunized with B. ovis ΔabcBA encapsulated with sterile alginate or with the non encapsulated vaccine strain. Serum, urine, and semen samples were collected during two months after immunization. The rams were then challen...
This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the anoestrus season. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; i...
Buffalo reproduction is considerably affected by late maturity, poor oestrus symptoms and long postpartum periods. This study was undertaken to evaluate the efficiency of Eazi Breed controlled internal drug release (CIDR), an intravaginal progesterone-releasing device, in relation to oestrus and fertility. Five hundred true anoestrus buffalo cows, in the age group 4-6 years in 10 villages of Dh...
Larvae causing obligatory myiasis are numerous and they may affect cutaneous and subcutaneous tissues, wounds, nasopharyngeal cavities (nasal bots), internal organs and the digestive tract (bots) of domestic and wild animals and humans as well. Nasal bots belong to the Family Oestridae, Subfamily Oestrinae, which includes several important genera: Oestrus, Kirkioestrus, and Gedoelstia infecting...
KŘIVÁNEK, I.: Impedance pattern of vaginal and vestibular mucosa in cyclic goats. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 4, pp. 109–114 The changes of vaginal and vestibular impedance during the oestrous cycle in goats were examined. The onset of oestrus was teased with a buck once a day during the experiment. Impedance was measured by a four-terminal method. The vaginal imp...
Context Detecting oestrus to facilitate the optimal timing of artificial insemination is key reproductive performance in dairy cows. Aims The aims present study were investigate relationship between activity and milk oestradiol concentrations during oestrus. Methods Accelerometers (IceQubes, IceRobotics Ltd, UK) used monitor (the number steps per day) 37 lactating Holstein–Friesian cows peri-oe...
