Wijnen H, van der Pol C, Papanikolaou A, Lammers A, Kemp B, van den Brand H, et al.
Poult Sci . 2022 Sep; 101(10):102092. PMID: 36055025
Colibacillosis is a poultry disease that negatively affects welfare and causes economic losses. Treatment with antibiotics raises concerns on antimicrobial resistance. Consequently, alternative approaches to enhance poultry resilience are needed....

Wijnen H, Molenaar R, Kemp B, van Roovert-Reijrink I, van den Brand H, van der Pol C
Poult Sci . 2022 Sep; 101(10):102088. PMID: 36055023
Early life experiences are known to be of great importance for later life. For instance, exposure to stress during early life can increase fearfulness at later age. In broilers, delayed...

Poult Sci . 2022 May; 101(7):101907. PMID: 35523033
Valgus-varus deformity (VVD) is one of the leg disorders affecting health and welfare of broiler chickens. In research, several protocols are used to determine the prevalence and/or severity of VVD....

Guz B, de Jong I, Bol U, Kemp B, van Krimpen M, Molenaar R, et al.
Poult Sci . 2022 Jan; 101(3):101647. PMID: 34998228
This study was designed to evaluate effects of source of macro and trace minerals (inorganic vs. organic) in fast and slower growing broiler breeders' diets on egg and hatchling mineral...

Nangsuay A, Molenaar R, Meijerhof R, van den Anker I, Heetkamp M, Kemp B, et al.
Animal . 2021 Aug; 15(9):100323. PMID: 34340139
Older breeder flocks produce eggs with a relatively larger yolk and thereby a higher nutrient availability than young breeder flocks. To optimise nutrient utilisation and embryonic development throughout incubation and...

van den Brand H, Meijerhof R, Heetkamp M, van den Anker I, Ooms M, Kemp B, et al.
Animal . 2021 May; 15(6):100223. PMID: 34030030
Carbon dioxide (CO) is considered to be an important factor during incubation of eggs. Effects attributed to higher CO concentrations during experiment might be due to confounding effects of other...

Poult Sci . 2021 Feb; 100(2):707-720. PMID: 33518124
This study was designed to evaluate the effects of green light emitting diode (LED) light during incubation and dietary organic macro and trace minerals during rearing on tibia morphological, biophysical,...

Wijnen H, van den Brand H, Lammers A, van Roovert-Reijrink I, van der Pol C, Kemp B, et al.
Poult Sci . 2020 Nov; 99(12):6619-6629. PMID: 33248577
Eggshell temperature (EST) during incubation greatly affects embryo development, chick quality at hatch, and subsequently various broiler physiological systems. Until now, a constant EST of 37.8°C seems optimal. Data on...

Wijnen H, Molenaar R, van Roovert-Reijrink I, van der Pol C, Kemp B, van den Brand H
Poult Sci . 2020 Aug; 99(8):3897-3907. PMID: 32731976
During incubation, development of embryos is affected by eggshell temperature (EST). A constant EST of 37.8°C has been considered so far to result in most optimal embryo development. However, it...

Poult Sci . 2020 Jun; 99(6):3020-3029. PMID: 32475438
This study was designed to determine effects of eggshell temperature (EST) pattern in week 2 and week 3 of incubation on tibia development of broiler chickens at slaughter age. A...
