Two 2 × 2 factorial experiments were conducted to investigate the interaction between cereal type (wheat v. barley) and exogenous enzyme supplementation (with or without) on odour and ammonia emissions (experiment 1) and growth performance (experiment 2) in grower-finisher pigs. The enzyme supplement used contained endo-1, 3 (4) - β- glucanase (EC 3.2.1.6) and endo-1, 4 - β-xylanase (E.C 3.2.1....
The effect of yeast culture (Saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 Brown Bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg ME (metabolizable energy) feed. Three groups were supplemented with 3 different levels of commerci...
the objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (sm) supplemented with an enzyme complex (ec). a total of 1920 animals of the cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four sm levels and three enzymes utilization types)...
A trial was conducted to evaluate the performance of broiler birds which supplemented with a commercial inactivated probiotic. Four hundred and fifty day old broiler chickens were allocated into 3 treatments with 6 replicates each. Each replicate was placed on clean wood shavings in floor pens receiving feed and water ad libitum. In treatment 1, feed was supplemented with 500 g/ton of a heat-in...
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...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in different sections of the gastrointestinal tract (GIT) of broilers fed wheat-based diets. A total of 120 7-day-old Arbor Acres broiler chicks were randomly allotted to two wheat-based experimental diets s...
abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
Diets containing low-quality durum wheat (716 g/kg) for production of pasta were used to feed male broiler chicks. The efficacy of xylanase supplementation and the impact of xylanase inhibitors on losses in exogenous enzyme activity were analyzed. Birds fed on the basal diet, not supplemented with recombinant xylanases or Roxazyme G, reached a BW of 1,509 g with a feed conversion ratio of 1.77 ...
