published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. the present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. eighty afshari cycling ewes were synchronized during breeding season using cidr for 14 days and assigned to 4 groups (n=20); group 1 received a si...

the aim of this study was to investigate the effects of different metabolizable protein levels in diet during the peri parturition on performance and blood parameters of afshari ewes and lambs. thirty two once lambing ewes in the last six weeks of pregnancy and the first six weeks of lactation with diets before and after parturition containing rates of nrc recommended and 20% higher one as low ...

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)...

this research was conducted to investigate the effects of fennel by product (fbp) on productive performance of growing lamb and in vitro gas production parameters, using 20 afshari×chal male lambs (bw = 49 ± 0.24 kg) were used in a randomized complete block design. experimental treatments consisted of diets including of 0, 3, 6 and 9% of fbp (dry matter basis). dietary treatments had no effect ...

Genetic improvement programs may improve disease resistance in animal production. The best-characterized genetic control of disease resistance and immune response in animals is the one associated with the Major Histocompatibility Complex (MHC). The ovine lymphocyte antigenof DRB1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...

specific structure of ewe's cervix is one of artificial insemination limitation in sheep. successful insemination in ewes has a close relation with morphology of their cervix. the objective of this experiment was to compare anatomical structure of cervix in makui, kurdish and afshari ewes. in this study, reproductive tract of 300 ewes of aforesaid sheep (100 ewes of each strain) were colle...
