Comparison of Two Different Serum-free Media for In Vitro Culture of Bovine Embryos

Journal of Animal Reproduction and Biotechnology, 2014
The aim of the present study was to compare two different serum-free media, modified synthetic oviduct fluid (mSOF) and modified potassium simplex optimization medium (mKSOM) containing 20% RD (RPMI1640 + DMEM, 1:1 v/v) (RD-mKSOM), for In Vitro culture ...

On-farm hatching and contact with adult hen post hatch induce sex-dependent effects on performance, health and robustness in broiler chickens

Peer Community Journal
To improve the early perinatal conditions of broiler chicks, alternative hatching systems have been developed. On-farm hatching (OFH) with an enriched microbial and stimulating environment by the presence of an adult hen is a promising solution.

HATCHING SYSTEMS IN SIAYA COUNTY

Journal of Engineering in Agriculture and the Environment
Poultry farming in Kenya plays a major role in complementing rural and peri-urban households’ food security and income. Farmers have turned to rearing of improved indigenous chicken (IC) due to the fast growth and high production of eggs; one of the strategies used to enhance development of IC is to supply day old chicks to producers.

A conventional hatchery vs. “on-farm” hatching of ducks in terms of microclimatic conditions and hatchability parameters - preliminary research

Journal of Applied Poultry Research
Summary: The hatching period is critical in the technology of artificial incubation of poultry. In mass production of chicks, hatching stress is increased by additional stressors that do not occur in natural conditions.

Hybrid System as a Source of Electricity in Hatching Duck Eggs

Abdimas Universal, 2021
In general, the source of electrical energy comes from PLN as the operator of the national electricity supply.  However, some consumers, such as farmer groups with quite large needs for electrical energy, require alternative energy sources to reduce operational costs.

Influence of light exposure during late incubation, early feeding, and litter access posthatch on the stress response and body weight gain in laying hen chicks

Journal of Applied Poultry Research
SUMMARY: In-ovo sexing opens the door to on-farm hatching in the laying hen sector, but knowledge on the implications of different hatching system factors remains limited.

Snakes: hatching of a model system for Evo-Devo?

The International Journal of Developmental Biology, 2014
Evo-Devo studies rely on a collection of animal model systems belonging to different phylogenetic branches to try and understand how organisms carrying a similar set of genes and pathways can develop into such a variety of shapes and sizes. The squamate clade, however, has only recently started to receive the attention it deserves in particular due to ...
