in this study 71 head of conceiving ewe and their progeny (91 head) from the flock of lori-bakhtiari sheep (360 head), in sholi station were randomly selected to determine the relationship between the immunoglobulin (igg) concentration in the ewe's serum and colostrum, and lamb's serum. ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...

background: the effect of heat stress on physiologicalparameters has been well documented. however, there arereports of a genetic based heat tolerance in some sheep breeds.objectives: the aim of the present study was to monitor thephysiological responses of an iranian fat-tailed breed againstheat stress and an acute stress insult. methods:atotal numberof 15 fall-born ram lambs were selected and...

Two experiments were conducted to examine effects of d-á-tocopherol (vitamin E) on colostrum immunoglobulin G (IgG) titers and preweaning lamb performance. Trial 1 consisted of 86 Suffolk ewes receiving either no vitamin E (control) or 1500 IU vitamin E on d-28 prepartum. From the 86 ewes, a subset of 25 ewes was randomly chosen for an intensive analysis of ewe serum and colostrum IgG and lamb ...

B13, one of the immunodominant antigens of Trypanosoma cruzi, is composed of repeats of a 12-amino-acid motif. Using synthetic peptides, the sequence FGQAAAGDK was previously shown to contain the B13 immunodominant epitope recognized by chagasic patients sera. To investigate the effects of neighboring sequences in the immunodominance, we tested serum recognition of two B13 sequences fused to La...

Effects of selenium on certain indicators of sheep reproductive success and on Se level in the sheep’s blood serum were studied in 2001-2002 on 100 Polish merino sheep ewes kept in a Western Pomeranian sheep farm. The 100 ewes were picked out on random and divided into two equal groups: treatment and control. The blood samples for serum Se assays were collected prior to administration of sodium...

To investigate the influence of maternal Se supply and plane of nutrition on lamb morbidity, mortality, and passive transfer of IgG, pregnant ewe lambs were used in 2 experiments with 2 × 3 factorial treatment arrangements. Supplementation of Se began at breeding and was either adequate Se (ASe, 9.5 μg/kg of BW) or high Se (HSe, 81.8 μg/kg of BW) in Exp. 1 or ASe (11.5 µg/kg of BW) or HSe (77.0...

Lyophilizatin of 13 cyanobacterial cultures belonging to seven genera was attempted in a variety of suspending substances. All organisms survived lyophilization when suspended in lamb serum. Some of the organisms could be successfully lyophilized in horse serum, beef serum, fetal bovine serum, or human ascites fluid. With the exception of Nostoc muscorium, none of the organisms survived lyophil...

A study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of Zandi lambs. The lambs were weaned at 45 and 90 days of age. The body weights and average daily gain (ADG) were monitored during the experimental period and 5 months of age. Cortisol, glucose, blood urea nitrogen (BUN) and lamb behavior (agitation, vocalization) were recorded bef...

OBJECTIVE The objective of this study was to compare the effectiveness and tolerability of three antifungal preparations, amphotericin B, liposomal amphotericin B (LamB) and amphotericin B colloidal dispersion (ABCD), in the treatment of neonatal Candida bloodstream infection (CBSI). PATIENTS AND METHODS All patients hospitalized in the neonatal intensive care unit from 1996 to 2000 with CBSI...
