The breeder thermal performances under a purge line break have been analyzed for two blanket design options: a blanket design using a packed breeder bed and a blanket design using a sintered breeder product. Under a purge line break open to a vacuum environment, the packed bed breeder temperature exceeds its operating temperature limit at a faster rate than that of the sintered breeder blanket ...

to achieve the desired level of animal performance providing animal food supplies containing mineral elements is essential. for this purpose, mineral elements of 8 important rangeland species, including ferula ovina, prangus uloptera, medicago sativa, lotus goeblia, trifolium montanum, melilotus officinalis, sanguisorba minor and stachys inflate, were measured at different growth stages in the ...

Minerals and vitamins play an important role in animal nutrition with beneficial effects on animal reproductive performance. To investigate this issue, 44 Ghezel ewes weighing 55±  2 kg (Mean±SD) and 2-3 years old were randomly divided into groups (n=11), to investigate the effect of the selenium and vitamin E supplementation on blood hormones and metabolites and possible reproductive performan...
