BACKGROUND Transfer of pesticides from environment to animal products is inevitable, so the purpose of the present work was to evaluate phosalone consumption via feeding with or without sodium bentonite (SB) on performance, blood metabolites and its transition to milk of Iranian Baluchi sheep. METHODS Twenty Baluchi ewes were divided into four treatments (P1 as control, P2, P3, and P4) of fiv...

introduction the longevity is normally defined as the length of its productive life in the flock, which is the amount of time an animal spends producing (1). longevity reflects the ability of ewe to avoid being culled for low production, low fertility, illness and influences the number and cost of replacements required to maintain the flock size. the benefit of increasing longevity are increase...

One hundred and fifty ewes with lifetime records of ovulation rate and lambing were divided into two groups on the basis of age, live weight and reproduction index (calculated from reproductive performance data). Both groups were synchronised in oestrus with progestagen sponges inserted for 14 days. At sponge removal one group received no PMSG while the other group received 400 i.u. PMSG. Eight...

Ewe productivity is a composite and maternal trait that considered the most important economic in sheep meat production. The objective of this study was application alternative genome-wide association (GWAS) approaches followed by gene set enrichment analysis (GSEA) on ewes’ genome to identify genes affecting pregnancy outcomes lamb growth after parturition Iranian Baluchi sheep. Three traits a...

a total number of 116,984 weight records belonging to 12,397 baluchi lambs reared in abbas abad breeding station during years 1978-2008 were used for phenotypic evaluation of maximum daily growth (mdg) and analysis of environmental factors affecting this trait. the initial data were performed by foxpro program and then gompertz non-linear model was fitted on the weight records of individual lam...

A total number of 136 pregnant ewes with the same age and parity were used in the present study. The experimental ewes reared during Arabic months or lunar months, from the 1 Gomady to Zol-hega, 1432 AH. The available data for each animal were obtained from the records of Sheep Farm, Project of Experimental Farms. Lambing season started at months, Shawal to Zol-hega. After lambing, the ewes wer...

The objective of the study was twofold: (i) to quantify the differences in daily milk yield (DMY) and total milk yield (TMY) between lame and non-lame dairy ewes and (ii) to determine the shape of lactation curves around the lameness incident. The overall study was a prospective study of lameness for the surveyed sheep population, with a nested study including the selection of matching controls...
