Past qs 12 Flashcards
Calculation of energy requirements of beef cattle
Transformation of ME to NEm X ME to NEg are different
NEm X NEg
Forage generally have
Increased Ca than P
Chemical maturity of animal measured
With in fat free DM content of the body, the proportion of protein … are constant
Overdose decreases the absorption of Zn and Mn
Ca
Zearaleon F 2 (fusraium 2) causes
Oesphagus symptoms (or pseudo estrogen)
Limited amino acid of extracted soybean meal
Met
What kind of barrier is built by epithelia cells in GI tract?
Anatomical
Carnitien
Meat
Bullterrier- prevent dermatitis
Zn (Bedlington terrier- Cu)
Omega 3 is what type of acid?
Linoleic acid
Omega 9
Oleic acid
Increase acid in feed in pig, dUA
Decreases daily wgt- gain
Goose stepping in pigs is caused by
Panthothenic acid deficiency, B5
Anti- cancer vitamin
b- carotene (vitamin A) (+ vitamin E?)
Decreases the feed digestion in carnivores
Wheat bran
DM min-> Max
Min: Silage Max: haylage
With what method can you measure O2 and CO2?
Indirect calorimetric method
Megadose of vitamin C can decrease toxicity of alpha toxin B1 In which animal
Poultry
CF in alfalfa haylage
20%
Causes secondary hypoparathyroidism in cat
Excessive P (hyper caused by vitamin D deficiency)
Optimal N: S ratio in dairy cow is
10:1 (sheep 7:1, Beef cattle: 15:1)
This vitamin (deficiency?) causes scaly dermatitis in pig
B6- exudative, generalised (Niacin B3- Dry, degeneralised)
In case of hairloss caused by biotin deficicy in cats one has to differentiate from:
Taurine deficiency
The inheritable imperfect Zn absorption is more frequent in
Dogs; husky, malamute, German Shepard
Inheritable copper retentation trouble is more frequent at
Bedlington terrier (Wilson. Menek disease, humans too, sex linked disease)
Put in in increasing order according to the energy level of cat, dog, cow milk
Cow, Cat, Dog
In case of secondary renal hyperparathyroidism this clinical sign will not occur:
Opistothonus (it occurs in uraemia, anaemia..)
When do we need to test digestibility of feedstuff with more animals
When the food cannot be fed to the animal because it is not physiological for it
MP is used in which animal?
Ruminants- MPE/MPN; to find many x/kg feedstuff microbes need to build proteins
BV?
Percent of digestible protein that is retained (shows protein quality)
FOM?
Fermented organic matter
Acidifiers?
Inorganic chemicals that either produce or become acids, increase level of gastric acid in the stomach // used as growth promoters - pigs!
What are probiotics?
Non-digestible food ingredients that beneficially affect the host animal by improving the intestinal microbial balance
What are prebiotics?
Non-digestible feed ingredients that beneficially affect the host by stimulating growth plus activity of one or limited numbers of bacteria (lactobacilli etc.) in colon.
What is the feeding level? (Formula)
FL = daily E intake/ daily E requirement for maintenance
What is inosite (myo-inositol)
Important in semisynthetic diets. In lab rodents, lack of showed retarded growth, intestinal lipodystrophy in females
L-Carnitine, what does it do? Deficiency in the dog causes?
Carries long chain FA to the mitochondria, source is meat
diets; lack of can lead to fatty liver and cardiomyopathy in the dog.
Flushing pig?
Biotin (B9)
Long-term control of feed intake?
(-)cholecystokinin + leptin (+) ghrelin
Fulfilment Unit?
How feedstuff fills the animal – fibre content. Dobermans
forage digestibility. 1UE decreasing effect on appetite caused by 1kg. 10ml from the standard pasture grass.
UFP?
Urea fermentation potential g/kgDM; potential of urea to be fermented in human based on energy level (give urea or not)?
CP in Peas?
20-25%
// Lupine 35-40 // Horse 25-30 // Soybean 33-40
Name a silage adhesive
Molasses
Hydrolytic decomposition of fat makes?
Glycerin, FAs,
divided by fungi, lipase, acid, metal ions, heat, and light
Oxidative Decomposition?
Production of Free Radicals – Peroxides
In nature it occurs in the form Phytonadion and Photomenadion?
Vitamin K
One of its main roles is protection
of mucous membranes?
Vitamin A, Niacin (B3), Vitamin U” All three [(a+b+c)] = (d)]
It is a constituent of Vitamin B12?
Co-Cobalt, needed for synthesis of B12; in Ru and Eq – by microbes
It may contain anti Vitamin E as antinutritive factors?
Cotton seed meal
In dairy cows, can reduce
incidence of mastitis?
Vitamin E
