Antimicrobial resistance in Escherichia coli isolated from on-farm and conventional hatching broiler farms in Ireland [PDF]

Irish Veterinary Journal, 2022
Background On-farm hatching (OH) systems are becoming more common in broiler production. Hatching conditions differ from conventional farms as OH chicks avoid exposure to handling, transport, post-hatch water and feed deprivation.

Effect of hatching time on time to first feed intake, organ development, enzymatic activity and growth in broiler chicks hatched on-farm [PDF]

Animal, 2021
The conventional commercial hatcheries used today do not allow the newly hatched chicks to consume feed or water. Combined with natural variation in hatching time, this can lead to early hatched chicks being feed-deprived for up to 72 h before being ...

A conventional hatchery vs “on-farm” hatching of broiler chickens in terms of microbiological and microclimatic conditions

Animal
“On-farm hatching” is one of the proposed alternatives to conventional hatchery-hatching. This solution reduces distress and improves the welfare of the chicks around the hatching period.

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

Peer Community Journal, 2023
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.

Comparison of performance, health and welfare aspects between commercially housed hatchery-hatched and on-farm hatched broiler flocks

Animal, 2019
On-farm hatching systems for broiler chicks are increasingly used in practice. We studied whether or not performance, health and welfare aspects differed between commercial flocks hatched on-farm or in a hatchery (control).

Hatching method correlates to early growth in chickens but not later performance [PDF]

Poultry Science
On-farm hatching has emerged as an alternative to conventional hatchery practices, in order to improve chick welfare, early growth, and overall production efficiency by reducing stress associated with post-hatch handling and transport.

Quail Eggs (Coturnic coturnic japonica)'s Fertility, Hatching Power, Hatching Weight, and Saleable DOQ at Quail Farm [PDF]

Andalasian Livestock
This study aims to determine the level of fertility, hatchability, hatching weight, and saleable DOQ of quail eggs (Coturnix coturnix japonica) at puyuh Farm. This study used 16-week-old quails kept in 5 battery cages, in one cage there are 5 levels with a sex ratio of 1:4. Village, Payakumbuh Timur District, Payakumbuh City, West Sumatra.

A conventional hatchery vs “on-farm” hatching of broiler chickens: hatching process dynamics, and biochemical and production welfare indicators

Animal
On-farm hatching (OFH) is presented as an alternative, welfare-focused approach to conventional hatching in a hatcher (HH). The objective of this study was to compare conventional hatchery hatching and two on-farm hatching systems in terms of ...

Research Note: Effects of on-farm and hatchery hatching on broiler performance, intestinal lesions, and immune response during a subclinical necrotic enteritis challenge

Poultry Science
: The effects of traditional and on-farm hatching systems on broiler performance and health under a subclinical necrotic enteritis (NE) challenge were evaluated in this study. A 2×2 factorial study explored the effects of place of hatch (on-farm hatched [

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.
