A Forage Allowance by Forage Type Interaction Impacts the Daily Milk Yield of Early Lactation Dairy Cows [PDF]

open access: yes, 2023
We tested for a forage allowance effect on the milk yield of early lactation dairy cow herds grazing swards sown with perennial ryegrass (Lolium perenne L.), white clover (Trifolium repens L.) and plantain (Plantago lanceolata L.) relative to perennial ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

A hierarchical 3-level meta-analysis of the effect of arginine supplementation on lactational performance in dairy cows and the associated influencing factors

open access: yesJournal of Dairy Science
: Arginine is one of the most versatile among the AA because of its important role in multiple functions of the body. However, the effect of Arg supplementation on lactational performance in dairy cows, and the associated influencing factors, have not ...

Effect of pre-calving body condition score and previous lactation on BCS change, blood metabolites, oxidative stress and milk production in Holstein dairy cows

open access: yesItalian Journal of Animal Science, 2017
The aim of study was to determine the effect of pre-calving body condition score (BCS) and previous milk yield on BCS change, blood metabolites, oxidative stress and milk production in Holstein cows.

Estimates of Genetic and Phenotypic Parameters for Milk Production in Moroccan Holstein-Friesian Cows

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2002
Heritabilities, repeatabilities and genetic and phenotypic correlations among milk yield, fat yield and fat percentage were estimated using an animal model and 20,140 records of 11,618 Holstein-Friesian cows enrolled in the Moroccan official milk ...

Milk Secretion Rate as Related To Milk Yield and Frequency of Milking

open access: yesJournal of Dairy Science, 1966
Abstract The rate of milk secretion does not seem to be related to intramammary pressure when the milking interval does not exceed 12 hr and daily production does not exceed 65 to 70 lb. At higher levels of production there is a question as to whether the secretion rate is diminished or whether the apparent decrease in secretion rate is due to ...

Effects of pregnancy on daily milk yield of Holstein-Friesian dairy cattle

open access: yes, 2004
First, second and third lactation curves of 21,885 first lactation dairy cows were allowed to vary depending on the months in milk at which the cow became pregnant. The curves were modelled using a 4th degree polynomial of days in milk. In the models for

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

open access: yesMolecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.
