Flashcards in 8a Life Cycle Nutrition of Cats 2 Deck (29):
What are the 4 objectives of a good feeding program for reproductive cats?
- good health and BC of queen throughout reproductive cycle
- optimal reproductive performance
- kitten health and development
- immune function of kittens
What are some of the negative effects of obesity during gestation?
- queens weight must be corrected before pregnancy
What is unique about the queen's energy requirement during gestation?
- loss of body weight after parturition even though feed intake is greatly increased
- due to lactation
How does weight gain differ between cats and dogs during gestation?
- dog: in last 4 weeks
- cat: linear weight gain from mating to parturition
How does weight loss differ between dogs and cats during gestation?
- dog: with giving birth
- cat: only 40% lost with birth, rest lost continuously during lactation
How much do you want weight to increase during gestation?
gain 40% of pre-mating weight
What does a linear weight increase do to energy requirement?
- increases linearly as well
Describe water requirement during gestation?
- increased need for water during pregnancy
- expansion of extracellular fluid compartments and maternal and fetal tissues
- also prepping for milk production
Describe protein requirement during gestation
- protein synthesis greatly increased (net tissue accretion and fetal tissue)
- protein quality and quantity important
- methionine first limiting amino acid
What are the effects of protein deficiency during gestation?
- decreased birth weight
- increased neonatal mortality
- decreased immunocompetence
What are the effects of severe protein deficiency during gestation?
- delayed home orientation in kittens
- aberant locomotor activity
- emotional responsiveness (cannot cry out)
Describe taurine requirement during gestation.
- required for normal reproduction and fetal development
What are the effects of taurine deficiency in gestation?
- delayed growth and development
- fetal death near 25th day of gestation
- fetal deformities
Describe fat requirement during gestation
- high energy demand during gestation
- improves productive performance
- DHA: neural development
- arachidonic acid: important for vascular development and regulation of blood flow
Describe the Ca and P requirement during gestation.
- increased demands for fetal skeletal development
- eclampsia can occur in late gestation with Ca and P deficiency (seizures)
- ratio is 1.1 to 1.5:1
Describe the Mg and Cu requirement during gestation.
- no restriction of Mg in reproducing queens
- Cu is cofactor in many metabolic pathways
What are some effects of copper deficiency?
- fetal death, abortions, craniofacial deformities, cerebral dysgenesis, histochemical defects of the aorta
What is the most energy and nutrient demanding life stage?
What does the nutrient requirements during lactation depend on?
- depends on number of kittens
How long do queens lactate for?
- 7-9 weeks depending on breed, kitten growth rate and management practices
What are the energy requirements during lactation?
maintenance + milk production
- energy content and yield changes weekly
When is peak milk production and peak energy demand?
What is there a discrepancy between at peak lactation?
- discrepancy in peak lactation and food intake
- can't eat enough to meet energy requirements
- at 8 week, discrepancy between how much kittens need and how much queen can provide (when weaning occurs)
What is 'L' in the energy requirement equation for lactation?
- Factor for stage of lactation from week 1 to week 7 = 0.9, 0.9, 1.2, 1.2, 1.1, 1.0, 0.8
Describe protein requirement during lactation
- increased demand for milk protein synthesis
- protein source highly digestible and high biological value
animal tissue preferable
Describe the fat requirement during lactation
- increased energy demands best met by feeding energy dense foods
- moderate to high fat foods enhance lactation performance
- higher fat food increases kitten survival and growth rate
What kind of diet is recommended for gestating or lactating?
- kitten diet
- increased energy density and increased fat
Describe Ca and P requirements during lactation.
- increased demands due to milk production
- Ca:P ratio = 1.1 to 1.5:1
