Economic Analyses of Feeding Systems Combining Pasture and Total Mixed Ration [PDF]

Journal of Dairy Science, 2003
Partial budgeting was used to compare net incomes of high-yielding Holstein cows fed either a total mixed ration (TMR), a pasture-based diet, or a combination of both. Variables included in the analysis were milk income, feed, feeding, manure handling, fencing, and water system expenses (revenues and costs based on 2000 values).

Maximising Lucerne (Medicago sativa) Pasture Intake of Dairy Cows: 2—The Effect of Post-Grazing Pasture Height and Mixed Ration Level

Animals, 2020
The effects of lucerne (Medicago sativa) post-grazing residual pasture height on pasture utilisation (vertical and horizontal), pasture intake and animal production were investigated in a sub-tropical partial mixed ration dairy system.

EVALUATION OF DIRECT-FED MICROBIAL SUPPLEMENTATION TO IMPROVE UTILIZATION OF THE LOW QUALITY ROUGHAGES IN RUMINANTS [PDF]

Arab Universities Journal of Agricultural Sciences, 2018
Direct-fed microbials (DFM) feed additives have been shown to improve average daily gain (ADG) and feed efficiency in ruminant animals in many studies.

Accuracy and precision of total mixed rations fed on commercial dairy farms [PDF]

Journal of Dairy Science, 2014
Despite the significant time and effort spent formulating total mixed rations (TMR), it is evident that the ration delivered by the producer and that consumed by the cow may not accurately reflect that originally formulated. The objectives of this study were to (1) determine how TMR fed agrees with or differs from TMR formulation (accuracy), (2 ...

Fermented total mixed ration technology and its application in tropical area

Siliao yanjiu, 2021
Fermented total mixed rations (FTMR) has high nutritional value, good palatability and long-term preservation. Vegetation in tropical area grows rapidly in summer and can be used as a by-product of animal feed.

The Survey of Particle Size of Total Mixed Ration in Korea [PDF]

Journal of Animal Science and Technology, 2003
This study was carried out to survey operation system of self-making TMR and particle size of self-making and commercial TMR, then to compare TMR particle size recommended by Penn State Particle Size Separator. Daily mixing time in self-making TMR averaged 48.6±28.0min., 2 augar type of mixer was most by 55.5% and daily 2 times of mixing in summer and ...

Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

Advanced Materials Interfaces, EarlyView.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Interference of ATP‐Binding Cassette Transporter by Functional Nano‐Delivery System for High Efficiency Management of Insecticide‐Resistant Nilaparvata lugens

Advanced Science, EarlyView.
A ZIF‐90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens. This system combines pH/ATP‐triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance‐breaking strategy.

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.
