Pigs of a high lean strain reared via an SEW scheme were self-fed a basal diet supplemented with 0, 15, or 30 mg niacin/kg diet from 10 to 27 kg body weight. The basal diet contained 18 mg of total niacin and 9.4 mg of bioavailable niacin per kg diet. Dietary niacin supplementation did not alter pig growth, efficiency of feed utilization, or body nutrient (protein, fat) accretion. Based on thes...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
The present study was conducted to investigate the effects of dietary lysine (Lys) and sex on growing quail performance and immunity parameters. The six dietary Lys: 10, 11.5, 13.0 (NRC 1994 recommendation), 14.5, 16.0 and 17.5 gr/kg were provided. The other essential amino acids except lysine were provided to meet or exceed NRC 1994 recommendation for growing quail. This experiment was carried...
this study was conducted to investigate effect of different sources of copper on gas production parameters and nutrients digestibility in zandi male lambs. in the first experiment, 18 male lambs (initial body weight 17.53±1.62) divided into three groups and fed one of the three experimental diets for 70 days. dietary treatments were control (basal diet without copper supplement), basal diet plu...
the study was conducted to evaluate the effect of different levels of synthetic lysine (slys) on dry matter intake (dmi), average daily weight gain (adg), dry matter conversion ratio (dmcr), carcass characteristics and economics of productionof finisher broiler chicks. as 240 day-old broiler chicks were randomly distributed to 12 pens of 20 chicks each and assigned to four treatment rations in ...
the application of nanotechnology in drug delivery and a variety of supplements is very impressive. in this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. in the present study aloe vera was extracted and its nanoparticles were produced. three levels of aloe vera nanoparticles in siberian sturgeon (acipenser baerii) were evaluated for th...
The objectives of this study include the determination of the growth potential of Naeini lambs when fed with diets varying in energy and protein concentrations and also an investigation of the influence of level of energy and/or protein intake on carcass characteristics and composition. Ninety Naeini weather lambs (initial live weight 29.89 ± 2.9 kg) were used in a 92-day feeding experiment. An...
