This study investigated the effect of dietary supplementation with calcium salts of fatty acids using 48 Afshari ewes randomly allocated to four treatments. All groups used in flushing period and only the source of energy were different between rations. The ewes were divided into four groups: A-barely grain; group B-received 5% of CSFA with source of flaxseed oil (w3); group C-received 5% of CS...

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)...

the objective of the present study was to investigate the effects of a sustained-release multi-trace element ruminal bolus on sex ratio, the reproductive performance and lambs growth of afshari ewes. eighty afshari cycling ewes during breeding season were used in the trial. the animals were synchronized using cidr for 14 days and assigned into 4 groups including: group 1 (n=20) received a singl...
