ANSC 4290 FINAL QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100% CORRECT ANSWERS)
/ALREADY GRADED A+
Quiz: 1) Only 32-46% of the protein synthesized in young (suckling)
animals is?
2) At intakes (energy and protein) above maintenance, protein
synthesis and degradation (protein turnover) are?
3) The energetic cost of protein turnover is?
Ans: 1) retained (older animals=24%)
2) both stimulated (the response in protein degradation is 24-33% less than
for protein synthesis, and so net anabolism results)
3) high
Quiz: 1) Most tissues recycle 80% of the amino acid derived from?
2) Strategies that target protein degradation would appear to be?
Ans: 1) protein breakdown, the remainder appears to be oxidized
(=irreversible)
2) beneficial in terms of improving overall energy and protein efficiency
Quiz: Whether the potential body protein deposition rate equals the
actual body protein rate is influenced by?
Ans: -supply of energy
-the minimum body lipid to protein ratio
,Quiz: 1) What is the input for the daily intake of available protein?
2) Differentiation is made between?
Ans: 1) daily available protein intake
2) -DE supplied by available protein/AA
-protein/AA free DE
Quiz: Describe daily intake of available energy
Ans: -gross energy content of (potentially) retained body protein=balanced
protein available for growth=Pd
- energy required to excrete excessive N (N, urea in urine+ associated 'ATP'
costs)
-energy value of protein is determined by its use (pd vs 'energy')
Quiz: 1) Maintenance energy requirements are given priority over?
2) E intake required to?
3) Represents energy requirements for?
Ans: 1) requirements for growth
2) maintain body weight (body energy constant)
3) vital body functions in non-producing animals (minimal activity, eating
and digestion; generating useful energy from dietary nutrients,
maintenance of tissues, blood flow, respiration, muscle tone, etc)
Quiz: 1) Maintenance energy requirements are normally expressed?
2) ME of maintenance is lost as?
3) Differences between groups of pigs can be quite?
Ans: 1) per unit of metabolic body weight
Examstudy - Stuvia US
,2) heat (retained E=0)
3) substantial
Quiz: In growing pigs, energy intake over maintenance is used for?
Ans: -body protein deposition (Pd); closely associated with lean tissue
gain=valuable body parts
-essential body lipid deposition (Ld); associated with Pd (determined by
minL/P); intramuscular fat and some depot fat
-extra body lipid deposition (Ld); closely associated with depot fat (sub-
cutaneous fat; peritoneal fat)- 'luxury' energy stores
Quiz: Why is there a marginal efficiency of energy utilization?
Ans: inefficiency is heat
Quiz: 1) During the 'Energy dependent phase of Pd', pigs show?
2) When energy intake exceeds energy requirements for maximum Pd
(and essential Ld), all extra energy intake is?
Ans: 1) Pd AND some Ld (essential body lipid; driven by minimal constraints
on the lipid to protein ratio in the pig's body, min L/P)
2) used for (luxury) Ld only
Quiz: Describe how there are some constraints on the ratio in which
energy is retained in body protein and body lipid (min L/P)
Ans: if energy intake is insufficient to support min Ld (minL/P) then Pd is
reduced to provide more energy for Ld (preferential amino acid
catabolism- of balanced protein)
Examstudy - Stuvia US
, Quiz: Describe expanding the simple model (making it more realistic)
Ans: -prediction of feed intake
-balance in which amino acids are required for various body functions
-represent energy utilization in terms of nutrient flows
-variation in maintenance energy requirements
-partitioning of energy intake over maintenance (in growing pigs between
body protein and lipid growth)
-energy and nutrient partitioning in gestating and lactating sows
Quiz: 1) What is the information required for accurate prediction of
feed intake in pigs?
2) Elaborate on animals' desired nutrient intake
3) Elaborate on potential constraints
Ans: 1) -animals' desired nutrient intake
-potential constraints
2) -basal nutrient requirements (='maintenance')
-desired body protein and body lipid retention rate, desired milk production
or growth of fetus and reproductive tissues
3) -physical feed intake capacity (gut fill)
-stresses that reduce growth performance (heat, crowding/social, disease)
-other stresses (nutrient imbalances, feed palatability, toxins, freshness, etc)
Quiz: What are the gender effects on feed intake?
Ans: barrow>gilt>entire male
