Prediction of Fat and Fat Free Live Weight in Broiler Chickens Using Backskin Fat, Abdominal Fat, and Live Body Weight
TL;DR: Abdominal fat weight was a better (higher r2) predictor of total fat, total fat minus abdominal fat, percent carcass fat, and percent intestinal fat, than percent backskinFat, and selection against percent abdominal fat would probably result in a reduction of fat in other locations and little change in fat free live weight.
Journal ArticleDOI
Abdominal and Carcass Fat in Five Broiler Strains
TL;DR: The results obtained were similar to those found previously in this laboratory with one strain of broilers, with no statistically significant differences between strains at the 5% level.
Journal ArticleDOI
Genetic Variation of Abdominal Fat, Body Weight, and Carcass Weight in a Female Broiler Line
TL;DR: The heritabilities indicate that it should be possible to reduce abdominal fat by selection, and the genetic correlations signify that a method has to be devised to increase body weight while simultaneously reducing abdominal fat weight.
Journal ArticleDOI
The Effect of Feeding High Energy Diets Containing Supplemental Fat on Broiler Weight Gain, Feed Efficiency, and Carcass Composition
TL;DR: In this paper, the effect of feeding two levels of energy in starter diets (3135 kcal metabolizable energy (ME)/kg low energy and 3410 kcal ME/kg high energy) from 0 to 28 days and finishing diets from 28 to 56 days was studied.
Journal ArticleDOI

TL;DR: White leghorn hen's eggs were coated with the following materials: acrylic resin, polyvinyl alcohol (P) as discussed by the authors, casein, Zein, and Epolene wax.
