the performance of new forage brassica plants were studied in ilam, iran, during 2012-2014 in a field experiment using a randomized complete block design with four replications. the treatments included, different forage crops perko, buko, oilseed radish, berseem clover, and the combination of three plants ramtil, phaselia, and clover. the studied traits consisted of plant height, forage yield, ...

The objective of this study was to investigate the effect of milking frequency (two times daily vs. three times daily) on the 305-d lactation milk, fat and protein yield and fat and protein percentage of Holstein dairy cows in Morocco. Data analyzed were 31400 records collected between 2009 and 2016 on 14272 cows raised in 194 herds. The frequency of milking had significant effects (P<...

the aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of romanian simmental dairy cattle. for the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...

this experiment was conducted to evaluate the effects of different levels of crude protein and probiotic in diets on performance, egg quality  and blood biochemical and immunity parameters of laying hens. a completely randomized design with factorial method (2×4) was conducted in which two levels of crude protein (nrc and 10% lower than nrc recommendation) and 4 levels of probiotic (0, .025%, 0...
