Terms in this set (25)

Prioritization and Nutrient Partitioning
1. Body growth
2. Increase in fat reserves
3. Puberty
Capital Breeders
Rely on body stores for a large portion of nutrients for reproduction
Income Breeders
Rely more heavily on consuming food for reproduction
Transamination
Transfer of the amino acid group of one amino acid to the carbon skeleton of a keto-acid (amino acid synthesis)
Deamination
Removal of the amino group from the carbon skeleton of an amino acid
Biological Value
The ability of a specific dietary protein to supply amino acids in the relative amounts required for protein synthesis by body tissues
Amino Acid Antagonism
Growth depression from an excess of one amino acid that can be reversed by adding a second amino acid
Amino Acid Toxicity
Growth depression from an excess of one amino acid that cannot be reversed by adding a second amino acid
Amino Acid Imbalance
Deficit of one or several amino acids that can cause depression in growth or production and can be reversed by addition of small amounts of the amino acid
Consequence of Low Dietary Protein
Reduced growth rate, increased fat, low milk or egg production, poor feed efficiency
Consequence of Severe Protein Deficiency
Reduced growth rate, weight loss, scruffy hair and other standard deficiency signs
Consequence of Excess Protein
High feed costs, normal growth, enlarged kidneys, excesss water intake
Consequence of Adequate Amino Acid Pattern but Low Energy in Diet
Reduced growth because amino acids are degraded and used as energy source
Lactation Ketosis
Can't keep up to demand for lactation
Pregnancy Toxemia
Can't keep up with demand for fetal growth in ewes carrying twins or triplets
Feline Hepatic Lipidosis
Most common hepatopathy seen in cats. Affects adult obese cats of any age sex or breed. Signs include anorexia, obesity, weight loss, sporadic vomiting, icterus, hepatomegaly, bleeding.
Essential Fatty Acids
Linoeic and linolenic
Biohydrogenation
Converts cis to a trans bond before removing the double bond
Saponification Number
Indication of the average chain length of the fatty acid
Iodine Number
A measure of unsaturation of fat
Fatty Acid Profile
Determine the actual concentration of each fatty acid in the oil (gas chromatography)
Hydrolytic Rancidity
Triglycerides are broken down to free fatty acids
Oxidative Rancidity
Double bonds of unsaturated fatty acids (PUFA) attacked by oxygen
Enterotoxemia
Clostridium perfringes bacteria grows rapidly with excess levels of starcj
Ruminal Acidosis
Consequence of feeding excessive amounts of rapidly fermentable carbohydrates with inadequate fiber
Low ruminal pH, depressed feed intake, and subsequent health problems
Negates the production gains accomplished by high grain feeding
