Symposium review: Integrating the control of energy intake and partitioning into ration formulation

open access: yesJournal of Dairy Science, 2023
: Energy intake and partitioning are determined by many interacting factors and their prediction is the Achilles' heel of ration formulation. Inadequate energy intake can limit milk yield and reproductive performance, whereas excessive energy intake will

Effects of fodder conservation and ration formulation interventions on dairy performance in Kenya

open access: yesInternational Journal of Agricultural Research, Innovation and Technology, 2020
Use of conserved forages and proper ration formulation has great potential to bridge the gap in dairy nutrition and reduce seasonal variations in milk yield.

Non-uniqueness results for entropy two-phase solutions of forward-backward parabolic problems with unstable phase [PDF]

open access: yes, 2013
This paper study the well--posedness of the entropy formulation given by Plotnikov in [{Differential Equations}, 30 (1994), pp. 614--622] for forward-backward parabolic problem obtained as singular limit of a proper pseudoparabolic approximation.

Using linear programming in balanced food design at minimum cost for cattle

open access: yesITEGAM-JETIA, 2018
Precision in ration formulation is important to achieve a proper balance of nutrients in the production of concentrate at the lowest possible cost in order to get a good food production and reproductive performance.

Prognostic significance of tumor microenvironment assessed by machine learning algorithm in surgically resected non‐small cell lung cancer

open access: yesCancer Reports, EarlyView., 2023
Abstract Background A methodology to assess the immune microenvironment (IME) of non‐small cell lung cancer (NSCLC) has not been established, and the prognostic impact of IME factors is not yet clear. Aims This study aimed to assess the IME factors and evaluate their prognostic values. Methods and Results We assessed CD8+ tumor‐infiltrating lymphocyte (

Grouping strategies and lead factors for ration formulation in milking ewes of the Chios breed [PDF]

open access: yes, 2008
The aim of this study was to develop an efficient strategy for ration formulation for milking ewes of the Chios breed in Greece. The strategy involved two and three groupings according to production level and challenge feeding using lead factors.

A New Approach to Equations with Memory [PDF]

open access: yes, 2009
In this work, we present a novel approach to the mathematical analysis of equations with memory based on the notion of a state, namely, the initial configuration of the system which can be unambiguously determined by the knowledge of the future dynamics.

Assessment of the variation in nutritional composition and safety of dried recovered food from United States households and prospects for use in chicken feed

open access: yesFrontiers in Sustainable Food Systems, 2023
IntroductionNew poultry feed valorization pathways for recovered household food could be enabled by commercially available household devices that dry uneaten food material, arrest spoilage, and preserve nutrient content. However, the nutrient composition,
