Resumen

El jarabe de maíz de alta fructosa (JMAF) en refrescos combate eficazmente el balance energético negativo (BEN) en ovejas. Este estudio encontró que el JMAF, no la carbonatación, es clave para el manejo de la cetosis en rumiantes pequeños.

Área de la Ciencia:

Medicina Veterinaria
Nutrición Animal
Metabolismo de Rumiantes

Sus antecedentes:

La cetosis y la toxemia del embarazo son trastornos metabólicos en rumiantes pequeños causados por el balance energético negativo (BEN).
Los tratamientos convencionales utilizan precursores glucogénicos, pero los agricultores buscan alternativas más baratas como los refrescos que contienen jarabe de maíz de alta fructosa (JMAF).

Objetivo del estudio:

Evaluar la eficacia del jarabe de maíz de alta fructosa (JMAF) y el agua carbonatada (agua carbonatada) para mitigar el balance energético negativo (BEN) en ovejas.
Determinar el componente principal de los refrescos responsable de mejorar el BEN.

Principales métodos:

Veintiocho corderas fueron puestas en ayuno para inducir el BEN y asignadas aleatoriamente para recibir 1 L de agua, agua carbonatada, solución de JMAF carbonatado (JMAF carbonatado) o Coca-Cola (Coca-Cola).
Se midieron las concentraciones de glucosa en sangre y beta-hidroxibutirato (BHBA) a intervalos posteriores al tratamiento.
Se utilizó análisis estadístico (ANOVA) para comparar los efectos del tratamiento en los niveles de glucosa y BHBA.

Principales resultados:

Tanto los tratamientos con JMAF carbonatado como con Coca-Cola resultaron en los valores más altos del área bajo la curva (AUC) de glucosa, significativamente más altos que el agua.
Los valores del AUC de BHBA se vieron afectados significativamente por los tratamientos, y el JMAF carbonatado y la Coca-Cola mostraron mayores mejoras en comparación con el agua y el agua carbonatada.
No se encontró una diferencia significativa entre el JMAF carbonatado y la Coca-Cola, pero el JMAF carbonatado mostró una tendencia hacia una mayor respuesta que el agua y el agua carbonatada.

Conclusiones:

El jarabe de maíz de alta fructosa (JMAF) es el componente principal de los refrescos que mejora el balance energético negativo (BEN) en ovejas.
El JMAF puede ser un suplemento energético práctico y económico para el manejo de la cetosis en la granja en rumiantes pequeños.

Energy Balance

Energy Balance

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Energy-requiring Steps of Glycolysis

Energy-requiring Steps of Glycolysis

Glucose is the source of nearly all energy used by organisms. The first step of converting glucose into usable energy is called glycolysis. Glycolysis occurs in the cytosol of the cell over two phases: an energy-requiring phase and an energy-releasing phase. Over the first three steps, glucose is converted into different forms and attached to two phosphate groups donated by two ATP molecules, resulting in an unstable sugar. In the next two stages, the unstable sugar splits into two sugar...

Internal Energy

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Balancing Redox Equations

Balancing Redox Equations

Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Energy Budgets

Energy Budgets

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
