Life stage nutrition Flashcards
Define life stage nutrition
Practice of feeding food that are designed to meet a pets optimal needs specific age physiological state
Objective of feeding
All nutrient requirements met
What are the 3 major life stages
Growth and repro, adult, senior/ geriatric
What are the goals for feeding during repro
Optimize conception, litter size, delivery ease, viability of young
3 phases of repro
Oestrus and mating, lactation, pregnancy
How does nutrition impact on Oestrus and mating
Need appropriate feed for chance of successful mating
Bcs
- ideal 3/5
Over/under weight have decreased ovulation rates, silent Oestrus, reduced litter size and milk production.
What is the impact of under and overweight on mating
Under
- embryo loss, poor fetal dev, low birth weight, fetal malformation fetal death, underweight young
Over
- dystocia, prolonged parturition, hypoxia young, still borne, increased caesarians
What is the normal weight gain for cats and dogs over their pregnancy
Dog
- 15-25% of bw prior to whelping
Loose portion of this post whelping
Cat
- gain weight early in pregnancy
Loose 40% immediately after birth and the remaining 60% during lactation
When should the growth diet be introduced?
From conception To weaning
What are then energy requirements for cats and dogs during pregnancy?
Dog
- Same energy requirement until 40days, then increases
Cat
- peaks at 6-7 weeks
From breeding give 1.6 x RER, increase to 2x RER parturition.
How should animals be fed in pregnancy
Ad lib unless obese
What is the protein requirement of cats and dogs preg
Cats
- >35% DM
Dogs
- 20-25% DM
What are the fat requirements during pregnancy
Increase in late preg to increase energy density of feed
Como for decrease vfi
What is the carb requirement during preg
Dog
- increase requirement for glucose last week
Cats
- increase carbs to 1% DM has protein sparing affect.
What are the ca:p ratios during preg?
Dogs
- increase req by 60% in last
Ratio 1:1
Xs= eclampsia
Cats
- ratio 1:1 -1.5:1
Eclampsia uncommon
