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 ...
the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. in this experiment, 192 day old female ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 replications. dieta...
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
the objective of the present study was to determine the effects of different levels of l-arginine in the diet on the growth performance, carcass traits, and blood parameters of female ross broiler chickens within their starter period. a number of, 192 day old female ross broiler chickens were fed with 4 dietary treatments in a completely randomized design, each dietary treatment had 4 replicati...
Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detect...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
The objective of the present study was to determine the best dietary level of L-arginine on the growth performance, carcass traits, and blood parameters of female Ross broiler chickens in the starter and grower periods. In this experiment, 192 day old female Ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 repli...
introduction: nutrition and health during the first days of life has critical effect on broiler chickens performance. it is well known that diet formulation based on digestible nutrients is superior to formulation based on total nutrients. the suitable supply of essential amino acids in broilers’ diets requires proper knowledge on their metabolic effects in the body. the excessive or unbalanced...
the objective of the present study was to determine the effects of feeding high levels of l-arginine on growth performance, blood metabolites, and carcass meat quality of female ross broiler chickens at the starter period. in this experiment, 192 day old chicks were fed with 4 dietary treatments (100%, 153%, 168% and 183% of digestible arginine, based on the ross catalogue recommendation) with ...
