Bovine granulosa cell culture for assessment of potency and specificity of antibodies to pregnant mares' serum gonadotrophin
Kuran, M; Broadbent, PJ; Hutchinson, JSM (Scandinavian University Press, 1996)Antibodies to pregnant mares' serum gonadotrophin (PMSG) neutralize the effect of PMSG in vivo and increase the number of transferable embryos when administered at the optimum time relative to the preovulatory luteinizing ... -
Development and de novo protein synthetic activity of bovine embryos produced in vitro in different culture systems
Kuran, M; Robinson, JJ; Staines, ME; McEvoy, TG (Elsevier Science Inc, 2001)In vitro matured (IVM) and fertilized (IVF) putative Day 1 zygotes (Day 0 = IVF) were allocated randomly to culture in formulations based on Synthetic Oviduct Fluid (SOF) medium and identified on the basis of their contrasting ... -
Development, amino acid utilization and cell allocation in bovine embryos after in vitro production in contrasting culture systems
Kuran, M; Robinson, JJ; Brown, DS; McEvoy, TG (Soc Reproduction Fertility, 2002)The effects of protein-supplemented and protein-free media on amino acid uptake, protein synthesis and cell differentiation in bovine blastocysts were investigated. Four formulations of synthetic oviduct fluid were used. ... -
Differential steroidogenic response of granulosa cells from different regions within a bovine follicle to FSH stimulation in vitro
Kuran, M (Scientific Technical Research Council Turkey, 1997)The objectiv of the present study was to investigate the steroidogenic capacity of granulosa cells from different areas within a bovine follicle. Bovine granulosa cells were isolated by gently scraping the inner layer of ... -
The effect of GnRH administration on plasma progesterone and reproductive performance in ewes
Two experiments were carried out to investigate the effect of GnRH administration at mating and on day 12 post-mating on the reproductive performance of Karayaka and Sakiz x Karayaka (F-2) crossbred sheep. In the first ... -
The effect of high dietary protein levels during late gestation on colostrum yield and lamb survival rate in singleton-bearing ewes
The study was carried out to determine the effect of crude protein (CP) levels in late pregnancy on the subsequent colostrum production and lamb survival rate. A total of 40 singleton-bearing Hampshire Down X Karayaka (F-1) ... -
Effect of macroscopic classification of bovine ovarian follicles on steroidogenic activities of granulosa cells in vitro
Kuran, M (Scientific Technical Research Council Turkey, 1999)This study aimed to investigate relationships between steroidogenic characteristics and abilities, and some macroscopic characteristics of bovine ovarian follicles and to relate this criterion to the physiological status ... -
Effects of a single injection of hCG or GnRH agonist on day 12 post mating on fetal growth and reproductive performance of sheep
Reproductive performance and fetal growth were determined when hCG (150 i.u. Pregnyl; n = 44), GnRH (4 mug synthetic GnRH agonist, buserelin, Receptal; n = 43) or saline (control, n = 45) was administered (i.m.) to ewes ... -
Effects of time spent near mothers postpartum on the behaviour of ewes and lambs; and on the growth performance of lambs in Karayaka sheep
The aim of the present study was to investigate the effects of post-partum separation of lambs from their mothers for various periods of time on the behaviour of lambs and ewe, lamb mortality, and lamb growth. Forty-seven ... -
Fetal growth and reproductive performance in ewes administered GnRH agonist on day 12 post-mating
Reproductive performance and fetal growth was determined in GnRH (4 mug synthetic GnRH agonist, Receptal) administered (i.m.) to ewes on day 12 post-mating (n = 103) compared to control ewes (n = 97) during the breeding ... -
GnRH agonist treatment on day 12 post-mating to improve reproductive performance in goats
Reproductive performance was determined in GnRH (4 mug synthetic GnRH agonist, buserelin, receptal; n = 37) and saline (control, n = 38) treated (i.m.) does on day 12 post-mating during the breeding season. Kidding rate ... -
The influence of pre- and post-mating protein supplementation on reproductive performance in ewes maintained on rangeland
The effect of short-term changes in level of protein supplementation during pre- and post-mating on non-return rate, lambing rate and litter size was investigated in ewes grazing on rangeland during early autumn. Groups ... -
Shearing pregnant ewes to improve lamb birth weight increases milk yield of ewes and lamb weaning weight
Milk yield, lamb birth weight and weaning weight responses to shearing during winter in sheep were investigated. A total of 46 Karayaka ewes were allocated into two treatment groups. Pregnant ewes in one group were shorn ...
