seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...

to evaluate the efficiency of nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. the experimental treatments included: 1) control (no additives)...

an experiment was conducted to determine the dietary digestible lysine requirement of male and female broiler chickens (arian) during the period from 6 to 21 days post-hatching. an amino acid-fortified basal diet containing corn and soybean meal as intact protein sources provided 20 % cp, and 3200 kcal amen / kg. in this experiment 150 male and 150 female chicks were allocated on the basis of b...

this study was conducted to evaluate the bioavailability of nano and micro sources of manganese in broiler chickens. two hundred and eight, 10-d-old male ross 308 broilers in a completely randomized design with 13 treatments, 4 replications and 4 chicks per replicate were studied for 35 days. during the experimental period, a basal corn-soybean meal diet containing 20 ppm mn (control treatment)...
