This study aimed to investigate the effects of pre-incubation in ovo injection with different levels L- carnitine (L-Car) on hatchability traits Bronze Turkey eggs, blood plasma constituents and subsequent growth performance hatched chicks. A total 300 hatching eggs were chosen (averaged 80.0 g) randomly divided into four main groups each three replicates (25 each). The 1st group was used as a ...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
a study was conducted to determine the efficacy of esterified glucomannan, sodium bentonite and humic acid, in counteracting the toxic effects of aflatoxin in experimentally contaminated diets (254ppbaf) fed to broiler chickens. 7-day-old male broiler chicks of similar weight were randomly assigned to one of the nine dietary treatments with four replicates of 12 chicks each. chicks were grouped...
previous results indicated that performance of chicks fed a high level (10%) of poultry by-product meal(pbm) was lower than performance of chicks fed a corn-soybean meal (sbm) diet. the latter difference was hypothesized to be due to variation in digestible amino acid (aa) levels among the diets. this study evaluated diets containing pbm formulated on equivalent total aa basis vs. an equivalent...
This study aimed to investigate whether pre- and early postnatal experiences of rearing hens contribute to the ability to cope with infectious challenges at an older age. In a 2 × 2 factorial arrangement, 352 Lohmann Brown chicks were exposed to either suboptimal or optimized incubation plus hatch conditions, and to cage or enriched rearing from week 0 to 7 of age. After week 7 all rearing cond...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...

The aim of this study was to investigate the presence of antibodies to ALV-J in broilers and broiler breeders. For this, 5 broiler units and 1 broiler breeding unit in the Marmara region were visited. Seventy 4-6 -week-old chicks from the broiler units, consisting of 14 chicks from each broiler unit, were selected. Seventeen chickens from the broiler breeding unit were also selected. The chicks...
