Efficiency of Selection for Broiler Growth at Various Ages

Energy Utilization from Various Fat Sources by Broiler Chickens at Different Ages

Two studies were conducted to estimate nitrogen-corrected apparent metabolizable energy (AMEn) of different fat sources for broilers from 1 to 7 and 28 to 35 d of age. Corn-soybean meal diets with inclusions of 2, 4 and 8% degummed soybean oil (DSO), acidulated soybean soapstock (ASS), or pork lard (PL) (experiment 1) and coconut oil (CCO), palm oil (PO), or palm kernel oil (PKO) (experiment 2)...

The response of broiler chicken to diet diluted with whole wheat at different ages

Efficiency of utilization of various sources of energy for growth.

The relative efficiency of dietary sucrose, protein sources, and fats in depositing body protein and fat (total energy) was directly estimated in young rats by feeding graded levels of each as supplements to a fixed amount of a basal diet that was presumably adequate in all essential nutrients except for energy. Under these conditions, the net gain in total body energy was a linear function of ...

Electroencephalograms of free behavioral chicks at various developmental ages.

A number of papers have been published dealing with the EEG in developing stages of the chick embryo], 5,11,21922,23, 4 29, 37) as well as with the EEG of early stages of chicks after hatching4, 8,11,12, 13,23, 24, 32). Investigations, however, under unrestrained unanesthetized conditions, into the correlation between the EEG and the behavior of immature chickens have been limited ; KEY and MAR...

The Changes in the Knee Joint at Various Ages

921 general levels of integration among human societies-the "primitive" and "civilized," and points out some universal features and some significant differences between them. R. Park asks the question: "What are the distinguishing characteristics of modern society?" and gives answers, such as size, complexity, speed, mechanisms, freedom. He ends on the hopeful note that, since men will still ma...
