Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Toward Numerical Modeling of Interactions Between Ice-Marginal Proglacial Lakes and Glaciers

Frontiers in Earth Science, 2020
Global climate change is evidently manifest in disappearing mountain glaciers and receding and thinning ice sheet margins. Concern about contemporaneous proglacial lake development has spurred an emerging area of research seeking to quantitatively ...

Environmental effects on progesterone profile measures of dairy cow fertility [PDF]

, 2006
Environmental effects on fertility measures early in lactation, such as the interval from calving to first luteal activity (CLA), proportion of samples with luteal activity during the first 60 days after calving (PLA) and interval to first ovulatory ...

Compensation Response to Hepatic Gluconeogenesis via β‐Hydroxybutyrylation of FBP1 and PCK1 in Dairy Cows

Animal Research and One Health, EarlyView.
(1) Kbhb modification of FBP1 and PCK1 is involved in regulation of the gluconeogenesis pathway. (2) Kbhb of FBP1 and PCK1 is catalyzed by p300 and removed by HDACs. (3) BHB induced an increase in the enzymatic activity of FBP1 and PCK1 through Kbhb modification at the K43 site of FBP1 and the K191 site of PCK1.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Calf management practices and associations with herd-level morbidity and mortality on beef cow-calf operations

Animal, 2016
The objective of this study was to investigate calf management practices on beef cow-calf operations and determine associations with herd-level morbidity and mortality of pre-weaned calves.

Genetic aspects of calving, growth, and carcass traits in beef cattle [PDF]

, 2003
The aim of this thesis was to learn more about the genetic background of calving, growth and carcass traits of beef cattle breeds in Sweden, and to assess the possibility of including calving traits and commercial carcass traits in the genetic evaluation.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

Animal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Modelled frontal ablation and velocities at Kronebreen, Svalbard, are sensitive to the choice of submarine melt rate scenario

Journal of Glaciology
Both submarine melt and calving are important for the overall mass balance of marine-terminating glaciers, but uncertainty is rife with regards to the magnitude of the processes. Modelling allows for these processes to be investigated without the need to
