Black soldier fly larvae meal and fat can completely replace soybean cake and oil in diets for laying hens

Poultry Science, 2021
Currently, there is a great interest in finding alternative protein and energy sources to replace soybean-based feeds in poultry diets. The main objective of the present study was to completely replace soybean in layer diets with defatted meal and fat ...

Effects of dietary fructo-oligosaccharides on laying performance and serum biochemical parameters of yellow broiler breeder hens [PDF]

E3S Web of Conferences, 2019
24-week-old local yellow broiler breeder hens were selected to study the effects of dietary fructo-oligosaccharides(FOS)or antibiotics(bacitracin zinc)on laying performance, serum biochemical indices and dietary mutrient metabolizability.

Metabolizable Energy Requirements of Pregnant Dairy Cows

Journal of Dairy Science, 1972
Abstract Energy balance measurements related the amount of metabolizable energy required by the pregnant cow to the stage of pregnancy. The amount of metabolizable energy required at term was 75% above that of a nonpregnant animal of equal weight. The increase in metabolizable energy requirement during the course of pregnancy was described by the ...

Supplementation of corn-soy-based diets with an Eschericia coli-derived phytase: effects on broiler chick performance and the digestibility of amino acids and metabolizability of minerals and energy.

Poultry Science, 2006
The effect of the supplementation of diets containing low available P concentrations with low and supra-activities of an Eschericia coli 6-phytase was assessed using growing broiler chicks. A total of 384 female Ross broiler chicks were weighed at d 1 of
