growth rate of 60 lori-bakhtiari single male lambs were assigned to a completely randomized design with two factors. the factors were tail status (with and without fat tail) and fattening period ( 75,90, 105 days). lambs were alternately docked by the use of rubber rings at the begining of the second day of birth. lambs were weaned at 90±5 days of age and randomly divided into three groups...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

This experiment was conducted to investigate the effect of oral administration and tissue injection of selenium and vitamin E on performance, blood metabolites and digestibility of nutrients in suckling Dalagh lambs. Eighteen lambs with 1-2 month age and the average weight of 13±2.7 kg assigned in a completely randomized design with three treatments and six replications. The treatments consiste...

learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...

G-protein-coupled receptor (GPR54) is one of the known gene affecting fecundity. This gene  affects  the ovulation rate and litter size performance. A total of 160 animals including Sanjabi (n=100) and Ghezel (n=60) were used to identify polymorphisms of GPR54 gene and  their influence on litter size. Genomic DNA was extracted by commercial DNA kit. The genotypic patterns were detected using th...
