This study investigates, in red-legged partridge (Alectoris rufa), the effects of the time to change from incubation to hatching temperature on egg weight loss, hatchability, chick weight at hatch, in...
The objective of this study was to determine if the bore diameter of needles used for in ovo injection of amino acids (AA) would affect subsequent chick hatchability. In Experiment 1, needles of diffe...
Non-coliform gram-negative bacteria like Salmonella, pseudomonas and proteus are the causes of yolk sac infection. In this study, we evaluated the effect of formaldehyde on the reduction rate of egg s...
The purpose of the present study was to establish the effect of the prolonged storage of Japanese quail hatching eggs upon the incubation performance and the quality of hatched quail chicks. The durat...
