Carcass growth is made up primarily of fat and protein. As cattle approach mature weight, carcass gain makes up a higher percentage of total gain. This is why dressing percentage increases with days on feed. Although performance is typically reduced for long fed cattle, adjusting performance for dressing percent can give us an indication of the performance of carcass growth. Fat makes up a high...

The effect of dietary Terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 Japanese quails was studied from 21 through 49 days of age. Dietary treatments included four levels of Terbutaline [0 (T0), 1 (T1), 3 (T3), and 5 (T5) mg/Kg of the diet]. Quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

To evaluate lactation performance and changes in plasma and fecal lipopolysaccharide (LPS) concentrations in response to the supplementation of Saccharomyces cerevisiae fermentation product (SC), two dairy farms were selected. On each farm, 32 cows in early to mid lactation (21 to 140 DIM) were blocked by parity and days in milk (DIM), and randomly assigned to one of the two treatments within b...

Consumers are concerned with fat consumption from meat products, and the ability to determine fat has changed with recent technological advances. The objective of this study was to predict fat percentage within marbling scores and compare 3 fat analysis procedures. Steaks (n = 119) were selected by USDA grading system using an E + V Vision Grading camera at a commercial beef plant during 1 d. T...

to explore the abnormalities in iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. body-fat percentage and resting 12-lead ecgs were recorded from all participants. of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. a total of 84% of the athletes demons...

Introduction: Complications of obesity and high fat in children are grave now and future. The aim of this research is comparing percentage of body fat in active and inactive girls using Anthropometric Parameters.Materials and Methods: This research is descriptive- correlation that 144 active(n= 70) and inactive(n= 74) girls aged 8 to 10 years old were selected by random cluster sampling method ...

An F2 chicken population of 442 individuals from 30 families, obtained by crossing a broiler line with a layer line, was used for detecting and mapping Quantitative Trait Loci (QTL) affecting abdominal fat weight, skin fat weight and fat distribution. Within-family regression analyses using 102 microsatellite markers in 27 linkage groups were carried out with genome-wide significance thresholds...
