effect of dietary mixture of prebiotic mannan oligosaccharide (mos) and β-1,3glucan, on growth performance, survival and body composition in grass carp juvenile (ctenopharyngodon idella) were investigated for 56 days. practical diets were supplemented with 0, 0.5, 1.5, 2.5 and 3.5 g/kg mixture of mos and β-1,3glucan in a totally randomized design trial in triplicate groups. the experiment carri...
this study compared the effects of different levels of dietary fat on growth performance, liver enzymes and blood biochemical of juvenile siberian sturgeon (acipenser bearii) was designed for 12 weeks. for this reason 135 fish (15.6 ± 0.33g; mean ± sd) at nine 500 liter fiberglass tanks, each one containing 15 fish. three experimental diets with the same protein (42 %) and 3 fat levels 10, 15 a...
this study evaluated the effects of drinking thyme essence (dte) (zero, 0.10, 0.15 and 0.20 ml/l) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. a total number of 500 day old male broiler chicks (ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (crd)....
اَبَر بتن خودمتراکم (high performance high strength self compacting concrete, hphsscc)، بتن نسبتا جدیدی است بدون نیاز به ویبره و با مقاومتی حدود 800 kg/cm2 که در صورت استفاده از آن در سیستم های پس تنیده، صرفه جوئی های بیشتری نسبت به چنین بتن هائی با نیاز به ویبره را بدست خواهد داد.
This study was performed in order to survey of effect of encapsulated oil in rain bow trout dietary on some growth factors and proximate compositions. Fish in average weight, 20 ± 1.5 g, was fed daily at 2.5 percent of biomass for 2 months. Rainbow trout was weighed every 2 weeks. At the end of experiment growth factors and proximate composition were studied. The result showed that the diets wh...
This paper reviews Brazil’s growth performance over the last quarter of a century and discusses the main determinants of a pick-up in growth since the mid-1990s. Emphasis is placed on the policy pay-offs associated with a consolidation of macroeconomic adjustment, which is a pre-condition for sustained growth. Structural reform based on a liberalization of the county’s trade and investment regi...

Several studies have demonstrated that poor early nutrition, followed by growth compensation, can have negative consequences later in life. However, it remains unclear whether this is attributable to the nutritional deficit itself or a cost of compensatory growth. This distinction is important to our understanding both of the proximate and ultimate factors that shape growth trajectories and of ...
The success of a Thoroughbred racehorse is determined by a multitude of factors, many of which are impossible to evaluate. Thoroughbreds are commonly selected for racing ability by pedigree and conformation analysis. There have been few studies associating growth and body size with racing performance (Pagan, 1998a; Cain, 2006; Smith et al., 2006). The genetic make-up, or genotype, contributes t...
