Bacterial isolations were attempted from milk samples taken from 242 range ewes in a southwestern Idaho shed lambing enterprise. Eighty-five percent of the ewe milk samples had no pathogenic bacterial growth at lambing and 3 weeks later. The few organisms that were isolated did not appear to affect udder condition of the ewe or contribute to lamb mortality. Shed conditions did not affect the fr...

________________________________________________________________________________ Abstract This study was conducted to evaluate the effect of breed types and lactation status on reproductive performance of hormonally-treated Awassi ewes. A total of 282 ewes were treated with intravaginal progestagen sponges and equine chorionic gonadotropin. Ewes were mated with fertile rams following sponge rem...

The study was conducted on 40 Polish Merino ewes divided into two groups: experimental (E) and control (C), each of 20 animals. Four weeks before, and then on day 1, week 3 and week 6 post lambing all ewes from group E were given intramuscularly 5 ml 0.1% Na2SeO4, 10 ml 10% ZnSO4 and 250 mg vitamin E. In milk sampled 7 weeks after lambing the concentration of conjugated linoleic acid (0.66% of ...

The effects of early weaning and exogenous hormones on postpartum estrus, conception and lambing performance were evaluated with 124 fall-lambed Karakul ewes. The broad outline of the experiment consisted of two lactation periods (nursing for 48 hr or 60 days postpartum) and four hormone treatment groups as follows: (1) a single injection of 2 mg estradiol-17/3 on day 4 postpartum and on the sa...

Animal losses due to abortion and malformed offspring during the lambing period 2011/2012 amounted to 50% in ruminants in Europe. A new arthropod-borne virus, called Schmallenberg virus (SBV), was identified as the cause of these losses. Blood samples were obtained from 40 goat flocks and tested for antibodies against SBV by ELISA, with 95% being seropositive. The calculated intra-herd seroprev...

Awassi and Assaf are local Israeli sheep breeds with prolificacies of ~1.30 and ~1.65 lambs born/ewe lambing (LB/EL), respectively. Introgressing the B (Booroola) allele of the FecB locus into these breeds led to the formation of prolific strains designated 'Afec Awassi' and 'Afec Assaf', in which lamb production under both intensive and semi-intensive conditions is higher than in the respectiv...

Colostrum provides newborns with nutrients and immunoglobulins that play a major role in the immune system. In this survey, immunoglobulin G (IgG) content, gross composition, mineral fatty acid composition were determined colostrum of Valle del Belice ewes aim evaluating effect lambing season. total, we analysed 60 bulk tank samples taken after during two seasons (summer winter). The IgG conten...

in this study, we aimed to investigate reproductive performance in estrus-induced zandi ewes treated with equine chorionic gonadotrophin (ecg) injection in combination with prostaglandin f2α (pgf2α)and gonadotrophin releasing hormone (gnrh) during non-breeding season. the estrous cycle was synchronized using controlled internal drug release (cidr) for 12 days. the ewes were randomly assigned to...

The aim of this study was to investigate the effects of two dietary metabolizable protein (MP) concentrations on the performance and health status of Afshari ewes and survival and growth of their lambs during late pregnancy. For 6 weeks prior to lambing, 32 Afshari ewes were randomly assigned to two dietary treatments, containing low (LMP) or high (HMP) MP concentrations. The ewes in LMP (n=16)...
