Q

Describe water requirement during gestation?

Q

Describe fat requirement during gestation

A
  • high energy demand during gestation

Q

Describe the Ca and P requirement during gestation.

A
  • 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

16
Q

Describe the Mg and Cu requirement during gestation.

A
  • no restriction of Mg in reproducing queens

- Cu is cofactor in many metabolic pathways

17
Q

What are some effects of copper deficiency?

A
  • fetal death, abortions, craniofacial deformities, cerebral dysgenesis, histochemical defects of the aorta
18
Q

What is the most energy and nutrient demanding life stage?

A
  • lactation
19
Q

What does the nutrient requirements during lactation depend on?

A
  • depends on number of kittens
20
Q

How long do queens lactate for?

A
  • 7-9 weeks depending on breed, kitten growth rate and management practices
21
Q

What are the energy requirements during lactation?

A

maintenance + milk production

- energy content and yield changes weekly

22
Q

When is peak milk production and peak energy demand?

A

3-4 weeks

23
Q

What is there a discrepancy between at peak lactation?

A
  • 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)
24
Q

What is ‘L’ in the energy requirement equation for lactation?

A
  • 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
25
Q

Describe protein requirement during lactation

A
  • increased demand for milk protein synthesis
  • protein source highly digestible and high biological value
    animal tissue preferable
26
Q

Describe the fat requirement during lactation

A
  • 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
27
Q

What kind of diet is recommended for gestating or lactating?

A
  • kitten diet

- increased energy density and increased fat

28
Q

Describe Ca and P requirements during lactation.

A
  • increased demands due to milk production

- Ca:P ratio = 1.1 to 1.5:1

29
Q

Describe the carb requirements during lactation.

A
  • no true carb requirement
  • carbs spare protein
  • provide substrate for lactose production
  • recommended >10% DM soluble carbs
