Effects of Ascorbic Acid Injection in Incubated Eggs Submitted to Heat Stress on Incubation Parameters and Chick Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-04-01)
Dose-dependent positive effects on hatchability and hatchling weight have been attributed to ascorbic acid (AA) when eggs were submitted or not to intermittent heat stress during incubation. Fertile breeder (Cobb (R)) eggs ...
Effect of High Incubation Temperature on the Blood Parameters of Layer Chicks
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
Adequate environmental temperature control is essential for incubation efficiency. Layer breeder eggs (n=360) were weighed and distributed in a completely randomized experimental design with two treatments, consisting of ...
In ovo feeding with 25-hydroxycholecalciferol influences bone mineral density of chicks
(Sociedade Brasileira de Zootecnia, 2021-06-21)
The purpose of this study was to determine if in ovo feeding with 25(OH)D3 could influence the incubation parameters of bone mineral composition, mineral density, and bone breaking strength in post-hatch broilers. Fertile ...

(INT SCIENCE SERVICES/BALABAN PUBLISHERS, 2008)
The family Alpheidae, composed by shrimps of relatively small size, popularly known as snapping shrimps, is the one of the most diverse decapod groups. These shrimps are found worldwide and Occur in tropical and subtropical ...
Optimal in-feed amino acid ratio for broiler breeder hens based on deletion studies
(Wiley-Blackwell, 2017-12-01)
An ideal amino acid ratio (IAAR) for breeder hens is needed for maximum nitrogen retention (NR) taking into account nitrogen deposition in body (NDB), feathers (NDF) and egg mass (NEM) to improve dietary protein efficiency. ...
Long-Term Mass Rearing Impacts Performance of the Egg Parasitoid Telenomus remus (Hymenoptera: Platygastridae)
(2020-01-01)
The effects of long-term laboratory rearing on the performance of Telenomus remus Nixon (Hymenoptera: Platygastridae), an egg parasitoid of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), were investigated by ...
Influence of incubation temperature on embryo development, hatchling morphology and early growth rate in red-footed tortoise (Chelonoidis carbonaria)
(2021-09-01)
Reptile embryos respond to temperature changes with metabolic and physiological adjustments that influence hatchling success, phenotype, behaviour, and growth rate. Climate change and global warming can affect the reptile ...
