Standardization and validation of ATP luminometry as a diagnostic tool to assess the cleanliness of feeding equipment in preweaning calves

Journal of Dairy Science, 2023
: The objective of this cross-sectional study was to standardize a reliable and repeatable swabbing technique using ATP luminometry (light emission proportional to the amount of ATP with result provided in relative light units [RLU]) to describe the ...

Replacing concentrates with a high-quality hay in the starter feed of dairy calves: II. Effects on the development of chewing and gut fermentation, and selected systemic health variables

Journal of Dairy Science, 2022
: Early development of the rumen, rumination, and fermentation is highly important in dairy calves. Yet, common rearing practices with feeding of concentrate-rich starters may jeopardize them because of lacking physically effective fiber (peNDF).

Improving growth rates in preweaning calves on dairy farms: A randomized controlled trial

Journal of Dairy Science, 2022
: Previous research has identified key factors associated with improved average daily gain (ADG) in preweaning dairy calves and these factors have been combined to create a web app–based calf health plan (www.nottingham.ac.uk/herdhealthtoolkit).

Effects of an optimized dairy calf-rearing protocol on performance and health in the subsequent fattening period on Swiss veal farms

Veterinary and Animal Science
We conducted a prospective field study to characterize the effects of an optimized rearing protocol of calves on dairy-farms on the subsequent performance, health and antimicrobial use (AMU) at the veal-farm. On 19 dairy-farms a total of 55 matched pairs

Comparison of three Mycoplasma bovis antibody ELISAs on serum from 3-5-week-old dairy calves using Bayesian latent class analysis

Irish Veterinary Journal
Background Controlling Mycoplasma bovis is challenging in veal and dairy beef systems that source young calves from multiple origins. Pre‑purchase testing may help reduce pathogen introduction, with serology being the most accessible option. Additionally,

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
