Six priming doses of 40 mg progesterone at two day intervals followed by 1,000 I.U. P.M.S. were superior to two priming doses plus P.M.S. in inducing oestrus. At the first insemination after induction of oestrus, fertility was normal in animals which received two doses, but depressed in those which received six doses of progesterone. An injection of 40 mg of progesterone after the injection of ...

Prostaglandin F~(Y, (PGF2a) causes luteolysis in several species of animals including cattle and sheep. This has led to investigations with PGF2a as an agent for the control of oestrus and ovulation in domestic animals (Inskeep 1973) and to comparison of PGF2a and progestins as practical methods of synchronizing oestrus in cattle (Smith 1973). This paper reports preliminary studies of the use o...

Background and Objectives: Today, 24-hours work is an unavoidable component in several industries. Night-work is an imperative situation for an important part of workforces. Shift-working is called to work at hours out of usual day-work time (7:00 am to 6:00 pm). The present study was a cross sectional descriptive-analytic research, and was carried out in order to investigate sleepiness and cha...

The use of exogenous gonadotrophins in puberty inducement and ovulation synchronization is a technique that has a positive influence on the management of swine. The purpose of this study was to verify the effects of a second gonadotrophin treatment [equine chorionic gonadotrophin (eCG) and luteinizing hormone (LH), intramuscularly (i.m.)] upon the second oestrus synchronization and fertility in...

Oestrus was induced 4-7 days after treatment with Cloprostenol (ICI 80,996) in gilts between 12 and 40 days pregnant. Fertility at this synchronized oestrus was good (85%).

Background: The objectives of a series of studies undertaken was to improve farm animal reproductive efficiency in terms of embryo production efficiency, conception rate and litter size by immunoneutralization of inhibin in conjunction with other conventional reproductive techniques. Materials and Methods: A recombinant porcine inhibin alpha-subunit mature peptide was produced by mass scale and...

Canine ehrlichiosis which becomes widespread worldwide is generated by a pathogen bacteria called Ehrlichia Canis. The prevalence of ehrlichiosis changes according to geographic regions in veterinary practice. The aim of this study was to determine the prevalence of the canine ehrlichiosis in Uşak, Turkey, together with clinical, hematological and biochemical signs. 100 dogs found in 6 differen...

Thyroidal function in goats as estimated by PBI values of blood serum showed a very high activity in oestrus, followed by that in pregnancy state. There was significant increase in PBI values between oestrus and non-pregnancy groups. The lack of significance between pregnancy and non-pregnancy values has been explained. Mean PBI values in oestrus, pregnancy and non-pregnancy were respectively 5...

This is a prospective study evaluating the efficacy of four clinical signs believed to be useful in the diagnosis of scaphoid fracture. Two hundred and fifteen consecutive patients with suspected scaphoid fracture were examined on two separate occasions to evaluate tenderness in the anatomical snuff box (ASB), tenderness over the scaphoid tubercle (ST), pain on longitudinal compression of the t...
