Acid-base balance assessments/tests

CHAPTER 3 General Nursing Assessments and Diagnostic Tests Related to Fluid, Electrolyte, and Acid-Base Balance 29... 

Chapters 1 and 2 are overview chapters that discuss the physiology involved in fluid, electrolyte, and acid-base balance. Chapter 3 discusses the diagnostic tests and basic nursing assessments related to fluid, electrolyte, and acid-base balance. 

It is well known that methionine (Met) and lysine (Lys) are two of the most limiting amino acids (AA) for milk and protein production in lactating dairy cows fed corn-based diets (Schwab et al., 2003 Rulquin, 2004). The NRC (2001) suggested concentrations of Met and Lys of 2.4% and 7.2% on a metabolizable protein (MP) basis, respectively, in order to maximize the use of MP for milk and milk protein yield by lactating dairy cows. However, it should be taken in consideration that these concentrations are hardly achieved. Nutritionists have two methods to fed lactating dairy cows with AA balanced diets one is to incorporate feeds with a high level of rumen undegradable protein, and the other is to supplement the diet with ruminally protected (RP) synthetic AA (Schwab et al., 2003). The aim of this work was to assess the bioavadabUity of a RP D,L-Met and a RP L-Lys HCl products by a standardized blood test (Sudekum et al., 2004).
