Multi‐omics reveals gastrointestinal metabolic disorder‐induced diarrhea in postpartum dairy cows

iMetaOmics, EarlyView.
Nutritional diarrhea is a pervasive, costly challenge in dairy production. Using integrated metagenomic and metabolomic profiling, we identified coordinated microbial and metabolic alterations across the rumen, hindgut, and serum. In the rumen, enrichment of Prevotella sp.

Effect of Body Condition Score at Calving on Adaptive Immune Function During Early Lactation in New Zealand Dairy Cows: Effect of calving body condition on adaptive immune function [PDF]

, 2014
The extent of postpartum negative energy balance in dairy cows is positively associated with body condition score (BCS) at calving. Results of epidemiological studies have indicated that calving BCS is positively correlated with several indicators of ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

JSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Frontal ablation trends of Manso Glacier, Northern Patagonia

Journal of Glaciology
Frontal ablation is a major component of ice loss in Patagonia but remains uncertain outside the Patagonian icefields. We present a multiple fluxgate method to quantify frontal ablation near the calving front, capturing spatial heterogeneity and complex ...

Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union: characterization, safety, and efficacy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The re‐evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expressed no interest.

OPTIMAL FEED COST STRATEGIES ASSOCIATED WITH EARLY AND LATE CALVING SEASONS [PDF]

Integer programming models were used to examine optimal monthly feeding strategies and costs for March and May calving alternatives. Body condition scores were allowed to fluctuate throughout the year except for calving and breeding periods.

Understanding natural variation in milk lipids: why parity and lactation stage matter for nutritional value

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Bovine milk is a major dietary source of lipids whose fatty acid (FA) profile shapes its nutritional and technological quality, yet its natural variation is commonly described using fixed days‐in‐milk windows that ignore individual peak‐yield timing and parity‐specific metabolism.

Productive efficiency of cows primiparous aberdeen angus of the body size and milk production levels

Bioscience Journal, 2016
Assessment of the productive efficiency of 30 primiparous Aberdeen Angus cows of different body sizes, classified at calving as heavy (375±10.5 kg) or light (283±7.7 kg), and different total milk-yield levels, classified as high (868±24.5 kg) or low ...
