Flashcards in 8a Life Cycle Nutrition of Cats 2 Deck (29):
1

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

2

What are some of the negative effects of obesity during gestation?

- stillbirths
- dystocia
- cesareans
- queens weight must be corrected before pregnancy

3

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

4

How does weight gain differ between cats and dogs during gestation?

- dog: in last 4 weeks
- cat: linear weight gain from mating to parturition

5

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

6

How much do you want weight to increase during gestation?

gain 40% of pre-mating weight

7

What does a linear weight increase do to energy requirement?

- increases linearly as well

8

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

9

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

10

What are the effects of protein deficiency during gestation?

- decreased birth weight
- increased neonatal mortality
- decreased immunocompetence

11

What are the effects of severe protein deficiency during gestation?

- delayed home orientation in kittens
- aberant locomotor activity
- emotional responsiveness (cannot cry out)

12

Describe taurine requirement during gestation.

- required for normal reproduction and fetal development

13

What are the effects of taurine deficiency in gestation?

- delayed growth and development
- fetal death near 25th day of gestation
- abortions
- fetal deformities

14

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

15

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

16

Describe the Mg and Cu requirement during gestation.

- no restriction of Mg in reproducing queens
- Cu is cofactor in many metabolic pathways

17

What are some effects of copper deficiency?

- fetal death, abortions, craniofacial deformities, cerebral dysgenesis, histochemical defects of the aorta

18

What is the most energy and nutrient demanding life stage?

- lactation

19

What does the nutrient requirements during lactation depend on?

- depends on number of kittens

20

How long do queens lactate for?

- 7-9 weeks depending on breed, kitten growth rate and management practices

21

What are the energy requirements during lactation?

maintenance + milk production
- energy content and yield changes weekly

22

When is peak milk production and peak energy demand?

3-4 weeks

23

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)

24

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

25

Describe protein requirement during lactation

- increased demand for milk protein synthesis
- protein source highly digestible and high biological value
animal tissue preferable

26

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

27

What kind of diet is recommended for gestating or lactating?

- kitten diet
- increased energy density and increased fat

28

Describe Ca and P requirements during lactation.

- increased demands due to milk production
- Ca:P ratio = 1.1 to 1.5:1

29

Describe the carb requirements during lactation.

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