The accuracy and efficiency of pregnancy diagnoses in cattle by pregnancy serum protein (PSP60) radioimmunoassay, a progesterone radioimmunoassay or oestrus detection were compared. Blood samples were taken from 349 suckling heifers and cows (1,191 inseminations) at 28, 35, 50 and 90 d post-insemination for PSP60 determination and at 22-23 d for progesterone. Females were declared nonpregnant w...

In this study, it is aimed to determine the length of estrus cycle, size of the preovulatory follicle, and ovulation time during the postpartum period (pp) in Anatolian jennies and to measure steroid hormone levels during the same period. Five healthy Jennies at late-stage of gestation were included in the study. During the post partum period, plasma progesterone (P4), total estrogen (E2) and 2...

The objective of the present study was to determine the accuracy and the negative prediction value of Pregnancy-Associated Glycoprotein (PAG) at 29 d post artificial insemination by ELISA. Blood serums of multiparous Holstein cows were used (n = 275). Pregnancy diagnosis was carried out by rectal palpation at 40 d and it was considered as reference test. Pregnancy results based on the PAG-ELISA...

BACKGROUND Laparoscopic trans-abdominal total mesorectal excision is technically demanding. Transanal Total Mesorectal Excision (taTME) is a new technique which seems to provide technical advantages. This study describes the results of taTME in a consecutive series of patients with low rectal cancer. METHODS From January 2012 to December 2013, a consecutive series of 26 patients with low rect...

This study was conducted to investigate the effect of clitoral massage on levels of estradiol (E2), testosterone (T), dehydroepiandrosterone sulphate (DHEA-S) and pregnancy rate in cows. For this purpose, 38 Holstein cows ranging from 3-6 years old were used. The cows were divided into two groups, as control (n=19) and application (n=19). The degree of intensity of oestrus expression was scored...

The influence of season on the plasma progesterone concentrations and morphometric values of corpus luteum and ovary was studied through ultrasonography in spring (n=10) and dry hot (n=10) seasons on alternate days during the estrous cycle regardless of estrous phases in Nili-Ravi buffaloes. The mean morphometric values of length and width of ovary and the diameter and area of corpus luteum wer...

Bali cattle have advantages in terms of adaptation and fertilization rates, but tend to slow growth rate because the rearing system is still grazing so that livestock becomes uncontrollable. This study aims determine peak mating calving estimation (Bos sondaicus) did not experience reproductive disorders, aged 4-7 years, belonging smallholder farmers. The were reared semi-arid area Netemnanu vi...

Guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)-stimulated phospholipase C (PLC) activity in bovine brain coated vesicles is inhibited by glutamate agonists. In the present study we show that quisqualic acid (QA), (+/-)-trans-1-aminocyclopentane-1,3-dicarboxylate (trans-ACPD), glutamic acid and ibotenic acid inhibited p[NH]ppG-stimulated PLC by 44, 41, 36 and 25% respectively. Carbachol ...
