Negative energy balance

Left displaced abomasum (LDA) occurs at high frequency in the early postpartum period and can affect production performance of dairy cows. Clinical diagnosis of LDA is usually done by abdominal auscultation and percussion. The purpose of this study was to explore the potential applicability of blood biomarkers for early warning and diagnosis of LDA in dairy cows.

Negative energy balance (NEB) is an imbalance between energy intake and energy requirements for lactation and body maintenance affecting high-yielding dairy cows and is of considerable economic importance due to its negative impact on fertility and health in dairy herds. It is anticipated that the cow hypothalamus experiences extensive biochemical changes during the early post partum period in an effort to re-establish metabolic homeostasis. However, there is variation in the tolerance to NEB between individual cows.

Fatty liver is a high incidence of perinatal disease in dairy cows caused by negative energy balance, which seriously threatens the postpartum health and milk production. It has been reported that lysine acetylation plays an important role in substance and energy metabolism.

Periparturient cows release fatty acid reserves from adipose tissue (AT) through lipolysis in response to the negative energy balance induced by physiological changes related to parturition and the onset of lactation. However, lipolysis causes inflammation and structural remodeling in AT that in excess predisposes cows to disease.

Identifying one or more biologically-active/native decoys from millions of non-native decoys is one of the major challenges in computational structural biology. The extreme lack of balance in positive and negative samples (native and non-native decoys) in a decoy set makes the problem even more complicated.

In the current study, we investigated, the possible relationship between vitamin E, selenium, high energy diet supplementation and its effects on serum metabolites. The present study was conducted on a total of 30 animals, 15 were in each group (Control and Treatment).

The experiment was conducted to investigate the effect of antioxidant [vitamin E (vit E)] and trace minerals [selenium (Se), copper (Cu), zinc (Zn)], high energy diet supplementation and its effect on allometric and physio-biochemical parameters in crossbred cows during transition period. For this, advanced pregnant crossbred cows (n = 20) of 2nd to 4th parity and lactation potential of >10 L/day at 28 days prepartum were divided into two groups viz. control (CON) and treatment (TRT) consisting of 10 animals each.

Psychological stress negatively influences food intake and food choices, thereby contributing to the development of childhood obesity. Physical activity can also moderate eating behavior and influence calorie intake.

Abstract Man is an omnivore and originally met energy requirements by hunting and gathering. Man evolved in an environment of feast and famine: there were periods with either a positive or negative energy balance. As an introduction to human energetics, this book on energy balance in motion starts with a chapter on animal energetics. How do animals survive and reproduce in an environment with a variable food supply? The examples on animal energetics illustrate how animals grow, reproduce and survive periods of starvation.

THE EXTENT AND TIMING OF PLANT GROWTH are controlled by the coordinated actions of positive and negative regulators. Some of the most obvious examples of regulated nongrowth are seed and bud dormancy, adaptive features that delay growth until environmental conditions are favorable. For many years, plant physiologists suspected that the phenomena of seed and bud dormancy were caused by inhibitory compounds, and they attempted to extract and isolate such compounds from a variety of plant tissues, especially dormant buds.
