this experiment was designed to evaluate the effect of phenolic components of scrophularia striata powder on feed intake, digestion and fermentation, rumination kinetic and rumen ecosystem in lori-bakhtiari sheep. in this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent scrophularia striata for one month. feed intake, digestibility, rum...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
This work aimed to study the effect of two different levels of ration energy supplemented with Alpinia officinarum. Rabbits were classified into six equal groups (G1-G6). The 1 and 4 groups received basal ration with 100 % and 90 % energy requirement and served as first and second control respectively. The 2 and the 3 groups received basal ration with 100 % energy requirement supplemented with ...
چکیده معضل چاقی به عنوان عارضه ای جدی برای زندگی بی تحرک و ماشینی، مورد توجه اغلب مراکز بهداشتی و درمانی دنیا قرار گرفته است. چاقی عامل زمینه ساز و در واقع عامل خطری برای بروز بیماری های قلبی - عروقی است که عموماً با کاهش طول عمر مورد انتظار و افزایش بیماری همراه است. هدف پژوهش حاضر تأثیر 12 هفته تمرینات ویبریشن کل بدن، تمرینات هوازی و تمرینات ترکیبی( هوازی و ویبریشن کل بدن) بر ترکیب بدنی زنان ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
The present study was conducted to evaluate the effects of dried citrus pulp(0, 5, and 10%) and pectinase enzyme supplementation (0 and 2000 unit per kg) on feed intake, body weight gain, feed conversion ratio, nutrient digestibility and the internal organ size of broiler chickens. A total of 240 one day old male Ross 308 broiler chicks were used in a factorial arrangement (2×3) based on a comp...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
A total number of 48 male growing New Zealand rabbits were used to study the effect of two different levels of ration energy supplemented with mixture of Lupinus albus L, Trigonella foenum-graecum L and Cassia senna L as feed additives. Rabbits were classified into four equal groups (G1-G4). The 1 and 3 groups received basal ration with 100 % and 90 % energy requirement and served as first and ...
Holstein calves were fed pelleted starter diets with crude protein (CP) concentrations of 18%, 22% and 24% per dry matter (DM) containing soybean meal (SBM) (SBM18, SBM20 and SBM24), respectively, for 10 weeks from 14 days of age. Another diet with a CP concentration of 18% per DM was tested using commercial xylose-soybean meal (XSB; Yasminomax) instead of SBM. Each diet was fed to 24 calves an...
this experiment was carried out to compare the effects of treated and untreated wheat straw with pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (bcs) after parturition. thirty kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. synchronization of estrus in sheep has been achieved with the use of i...
