RISSelection for the parthenogenetic trait in chinese painted quail (coturnix chinensis) affects hatchability parameters
The Effect of Dietary Supplementation of Prebiotic and Probiotic on Performance, Humoral Immunity Responses and Egg Hatchability in Broiler Breeders
In this experiment, the influence of prebiotic and probiotic supplementation in the broiler breeder diets on body weight, mortality, feed intake, egg production, hatchability and humoral immunity response was investigated. A total number of 13140...
Effect of In Ovo Injection of VG/GA Vaccine, an Apathogenic Enteric Strain of Newcastle Disease Vaccine and Aluminum Hydroxide as an Adjuvant on Hatchability and Immune Response of Commercial Pullets
was further subdivided into two groups and one of these groups received ND-B1 vaccine on day seven posthatch.
Lowest hatchability was recorded in groups vaccinated with doses of 105 and 106 EID50. On day 21, the highest hemagglutination inhibition (HI...
A Study on physical properties of ostrich egg to estimate the egg fertility
Currently one of the blockade problems in ostrich egg production industry is the impossibility of egg candling prior to hatching for fertility determination. Therefore, a fraction of the hatchers always occupies by infertile ...
Fertility Recognition of Ostrich Egg Using Physical Properties
The aim of this study was to investigate some physical properties of ostrich egg, including eggshell porosity, dimensional and gravimetric properties which were nondestructively measured to find any probable correlation ...
Effects of storage temperature and length of the storage period on hatchability and performance of red legged partridge (Alectoris rufa) eggs
neural network model as a new powerful tool to describe and predict hatchability of broiler breeder eggs
to describe relationship between age of broiler breeder and hatchability. Neural Network model was developed with the Matlab program. The predictive quality of the Neural Network model was tested for an external validation set of 10 weeks randomly chosen from...
Assessment of feeding extruded flaxseed on egg characteristics, hatchability, and growth performance of English white quails
Objectives: This experiment was performed to investigate the effects of dietary incorporation of
extruded flaxseed on egg characteristics, hatchability, and growth performance of English white
quails.
Materials & Methods: A...
Effects of in ovo injection of threonine on hatchability, intestinal morphology, and somatic attributes of Japanese quail (Coturnix japonica)
A total of 540 Japanese quail eggs were in ovo-injected at day 11 of embryonic development to evaluate the effects of in ovo feeding of threonine (THR) on the hatchability, somatic attributes, and gut morphology of hatchlings. A completely...
