Genetic parameters for milk yield and lactation persistency in the three first parities of Iranian Holstein cows

open access: yesRevista Colombiana de Ciencias Pecuarias, 2019
Background: Lactation persistency influences cow health and reproduction and has an impact on the feed costs of dairy farms. Objective: To estimate (co)variance components and genetic parameters of 100- and 305-d milk yield, and lactation persistency in ...

Effect of milking time on yield, composition, and antimicrobial components of milk in lactating goats

open access: yesAnimal Science Journal
AbstractVarious studies have attempted to improve the milk yield and composition in dairy animals. However, no study has examined the effects of milking at different times on milk yield and composition. Therefore, this study aimed to compare the yield, composition, and antimicrobial components of milk obtained from milking at different times in ...

The Milk Yield Response to Frequent Milking in Early Lactation of Dairy Cows Is Locally Regulated [PDF]

open access: yesJournal of Dairy Science, 2007
Frequent milking during early lactation of dairy cows increases milk production throughout lactation; however, whether this response is regulated systemically via lactogenic hormones, locally in the mammary gland, or both is unknown. We hypothesized that the effects of frequent milking on milk production during early lactation are regulated via local ...

A Metabolic‐Epigenetic Axis of AARS1/IGF2BP3‐K280 Lactylation Sustains Endometrial Cancer Stemness and Recurrence

open access: yesAdvanced Science, EarlyView.
Lactate‐driven endometrial cancer relapse is mediated by enzymatic protein modification. Elevated lactate levels activate AARS1, which catalyzes K280 lactylation of IGF2BP3, therefore stabilizing HMGA2 mRNA and promoting tumor stemness and recurrence.

Prediction of lactation milk yield using various milk recording methods

open access: yesBiotechnology in Animal Husbandry, 2008
The objective of this study was to determine the effect of various milk recording methods (A4, AT4, A6, AT6) on prediction accuracy of 100, 200 and 305-day milk yield. The data used in this study were 11,430 individual test-day milk yield records collected from November 2004 to November 2006 on 813 cows reared on 15 family farms in Croatia.

Prediction of Standard lactation Milk Yield from Completed Lactations of Longer Duration in Cattle and Buffaloes [PDF]

open access: yesPakistan Veterinary Journal, 2012
The aim of this study was to develop a procedure to adjust lactations of longer duration to a standard such as 305-days when standard lactation milk yield for such lactations could not be recorded.

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

MILK YIELD DURING PROLONGED LACTATION IN MICE; EFFECT OF OVARIECTOMY [PDF]

open access: yesReproduction, 1969
Prolongation of lactation beyond its natural duration has been induced in rats (Bruce, 1958, 1961; Nicoll & Meites, 1959) and mice (Parkes, 1926; Selye & McKeown, 1934; Fekete, 1940; Mühlbock & Tengbergen, 1961; Zeilmaker, 1968) by regular replacement of the suckling litter.
