an experiment was conducted on 240 one-day old ross 308 broiler chicks using a completely randomized design in a 2×3 factorial arrangement with two levels of nano-adjuvant (with and without) and three levels of dietary protein (low, medium and high) during a 42 d experimental period. the main effect of protein density on feed intake was significant during the starter and grower periods (p

Abstract: ِIntroduction: The effect of morphine dependency on learning and spatial memory is controversial. So in this study effect of co-administeration of nitric oxide (NO) and morphine in CA3 of hippocampus on learning and spatial memory in morphine dependent rats was investigated. Methods: After anaesthetization of male rats, cannulae implanted bilaterally in CA3 of hippocampus. After reco...

this experiment was conducted to determine the effect of feeding alfalfa hay and starter fiber level on feed intake and performance of holstein dairy calves, using thirty two male calves in a completely randomized design assigned to four diets in a 2×2 factorial arrangement. the experimental treatments were as follow: t1: starter with low fiber and without alfalfa hay, t2: starter with low fibe...

The present study aimed at evaluating the effect of the probiotic thepax and yogurt (as probiotic) on the growth response and intestinal microflora results of broiler chickens. Two hundred forty day-old Ross 308 broilers were equally distributed into 12 floor pens and reared for 42 day. The treatments consisted of yogurt (10, 5 and 2.5% during starter, grower and finisher periods in the drinkin...

Airway nitric oxide production is decreased in cystic fibrosis. As growth hormone therapy has been shown to increase nitric oxide production in growth hormone-deficient patients, it may also affect nitric oxide production in patients with cystic fibrosis. The objective of the present study was to investigate the effect of growth hormone therapy on systemic and airway nitric oxide formation in p...

The survival of inoculated in fermented sausages Listeria monocytogenes strain was studied. The sausages were prepared with and without starter cultures. The survival limits of L. monocytogenes and lactic acid bacteria (LAB) were determined as colony forming units per gram (cfu g) depending on water activity (aw) and pH on 0, 1 , 3, 5, 7, 14 and 21 days of maturation. The decreasing water activ...
