NutrtionQuestion 1 If you are feeding a ration that is “perfectly” formatted on paper (ie, meets all requirements), but the animal is not growing/performing as predicted, it could be because the ration/diet either doesn’t contain the nutrients you think it does or that the nutrients present are in a low or degraded quality. (this scenario serves as an example of how several of the topics discussed can be tied together in a “real-life” example.)
A How would you analyze the diet for crude protein and amino acids or look for indicators of quality? What could reduce protein quality? How would you then improve total diet protein quality if you find it is low? Are the strategies different for ruminants and nonruminants?
B there essential fatty acids that could be missing? Can this be determined by a crude fat analysis? If not, how would you determine it?
C How do fiber fractions (NDF, ADF, lignin, etc) influence use by the animal, specifically for ruminants and nonruminants? Is the digestion/absorption of other nutrients altered by these fiber fractions of the diet?
D Is it important to measure feed intake? What would change if the animal is not consuming the amount you think they are? Say you know the degradability of each feedstuff, is it still important to know the passage rate? Does feed intake influence passage rate and digestibility?

Explanation / Answer
A. Quality indicator (biological value) for crude protein / amino acid in animal feed / diet is the chemical score (CS) for the amino acids present in the protien feed, obtained on comparison of the feed protein to that of ideal protein. CS is calculated as follows:
CS = Amino acid in test feed (g / 16g N) / Amino acid in ideal protein (g / 16 g N) * 100
A good quality protein will be that for which the amino acids score pattern is close to that of the ideal protein.
Poor quality protein feed could be a result of abundant supply of cheap quality protein in the market.
If the animal feed is found to be of poor quality, the feed can be supplemented with appropriate quantity of those amino acids which are having score below 100.
The strategies will be different for ruminant and non-ruminant animals as they differ in their digestive system. Non-ruminant animals have only single compartment stomach.
B. Essential fatty acids can be determined by crude fat analysis.Crude fat is extracted from animal feed with diethylether by Randall method, also known as Sortex method or Submersion method.
C. Yes, the fibre fractions affect the absorption and digestibility of other nutrients in animal feed, and these effects may be different for ruminant and non-ruminant animals.In fact, the feeding (nutritional value) of animal feed is limited by its relative fibre content. Fibre content reduces the energy value of the feed.
However, low fibre fraction show better feeding value for non-ruminant animals, whereas high fibre fraction can be given to ruminant animals as these animals have little impact of fibre content due to their digestive system makeup.
D. It is definitely necessary to measure feed intake.This is because the energy requirements are different for ruminant and non-ruminant animals, as the feed intake in animals is both chemically and physically controlled. Degradibility fo the Feed stuff influence the passage rate and determining the passage rate is required to schedule the feed frequency. If all these factors are not properly controlled, it may lead to digestibility problem in animals and affect their productivity and health.
