Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Digital Quantum Simulation of the Holstein Model in Trapped Ions

, 2012
We propose the implementation of the Holstein model by means of digital methods in a linear chain of trapped ions. We show how the simulation fidelity scales with the generation of phononic excitations.

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

Animal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market

Growth Hormone Promotes Lipolysis and Impairs Insulin Sensitivity by Activating the ERK/HSL Signaling Pathway in Bovine Adipocytes

Animal Research and One Health, EarlyView.
This study was to evaluate the role of GH in lipolysis and insulin sensitivity in bovine adipocytes and clarify the underlying mechanism. Our findings demonstrate that GH activates ERK/HSL signaling pathway, promotes lipolysis, and impairs insulin sensitivity in bovine adipocytes.

Polarons and bipolarons in strongly interacting electron-phonon systems

, 1995
The Holstein Hubbard and Holstein t--J models are studied for a wide range of phonon frequencies, electron--electron and electron--phonon interaction strengths on finite lattices with up to ten sites by means of direct Lanczos diagonalization. Previously

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Single polaron properties of the breathing-mode Hamiltonian

, 2007
We investigate numerically various properties of the one-dimensional (1D) breathing-mode polaron. We use an extension of a variational scheme to compute the energies and wave-functions of the two lowest-energy eigenstates for any momentum, as well as a ...

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Understanding the Market for Holstein Steers [PDF]

A semi-structured interview process was combined with an econometric analysis to document the newly changed structure of the Holstein sector, to evaluate existing quality perceptions, and to assess the impact that recent changes in production practices ...
