the present study was aimed to improve the reproductive performance of corriedale ewes by nutritional flushing. forty corriedale ewes were divided into four treatment groups (tc, t1, t2 and t3) with 10 ewes in each group (n=10). at the beginning of the breeding season extra feeding (flushing regime) was started for approximately 34 days such that two estrus cycles were covered. first group i.e....

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

in order to study of sodium nitroprusside(snp) application effect on growth indices and water use efficiency of kidney beans cultivars(akhtar and derakhshan) under water deficit stress, an experiment was conducted in split factorial based in randomized complete block design with three replications in bu-ali sina university research field at 2012. water stress treatments included vegetative stre...

In this study phenotypic and genetic factors affecting the reproductive efficiency of Lori-Bakhtiari ewes were determined using 8202 reproductive records of 2478 ewes collected at Shooli research station in the southwestern part of Iran (Shahrekord) during 1989 to 2012. Reproductive efficiency over all consecutive lambing opportunities were calculated by adding the total reproductive efficiency...

Students in Reproductive Management (a senior-level course with approximately 20 to 50 students per semester) at the University of Missouri-Columbia are required to participate in a simulation exercise that is designed to improve reproductive efficiency in a beef herd. During a simulated 5-yr period, students must 1) improve reproductive efficiency in a beef cow-herd through implementation of r...
