Past qs 9 Flashcards
Full- fat soya heat- treatments is done by
Uni-pro-soya
Protein content in cereals
10-14%
With induced amino acid maltian
Increases essential amino acid production
Antivitamin K
Dicumarol
Bad effect of GI parasites is given
Less nutrients available for host
How much the animals eats, is regulated by
Short time regulation
It can cause abortion
“PRRS (porcine reproductive and respiratory syndrome virus)”
For bacterial prevention
Drastic barrier: Complete exclusion of exogenous microbes
Permissive barrier: Limitation of bacterial multipicaton
Reportioning compounds
B2 agonist: Increase protein and decrease fat
What is heat treatment and what are the possible methods
Reducing, pelleting, – fusion, expanding, rosting, toasting, microcave drying, infrared drying, direct hot- drying, hydrothermal flaking
How to measure energy metabolism
Direct calorimeter (bio- calorimeter: energy combustion) Indirect: calorimeter (CO2/O2= RQ)
Acid value
Mg (KOH) required to neutralize 1g fat
Peroxidase value
Ml Na- thiosulphate /100g fat (limit 25-30)
What is the H2O content of the muscle?
70-80%
Animal derived feed contain a lot of
Teston..
The discount factor of corn silage 0,053 means that by increase feeding level the digestibility will
The digestibility of corn silage will decrease by 5,3%
It is calculated from the parametes determined by chemical analysis
Organic matter (DM - Ash)
One of its deficiency syndromes is oedema of eyelids
Vitamin B6 (pyridoxine)
Low DM but bulky (bulky and concentrated?)
Milk: bulky and concentrated
What is RQ?
1 in Ch, 0 in fat, 0,83 in protein
Feeding standards
NCR (minimum requirements) (ARC, NRA, DLG= optimal requirements)
What causes curled toe disease?
Deficiency of B2 (riboflavin)
What vitamin causes oedema
Pyridoxine (B6)
Of the eyelid-> B6 deficiency
Indicator in faeces given orally
Mn
Zn
Inales
Mn and P
Females
Estrus determinated by..
Energy (heifers)
Combustion energy of uric acid
34,4 KJ/g
A complete premix content
Premix + macrominerals+ aa supplement (+urea)
Vitamin, micro + macro elements 2,5-8%
- One should calculate with the content of faecal loss in:
2. One should calculate with the content of urine and gas loss in:
- DE
2. ME
Why is it forbidden to use STH as a growth factor
Long time fat mobilization
Substitution number
How many kg DM intakes will decrease from forage by adding 1kg DM concentrate
Buffer capacity of bone and egg shell
Some
Buffer capacity of milk
None
Feed intolerance
No real answer
In investigation of feed stuff you can detect
Feather and fish meal
What is Eubiosis
Main flora is >90% of total flora
What is Metabiosis
Relationship between 2 spp. Where 1 is dependent on the products of the other
What is Disbiosis
The typical distribution of microbes has broken up causing increase on host
Tables can contain only total P of the feed but also the amount of
Available P
Is roughage requirements for a day is at least 0,5kg/100kg bw
Horse
The supply of this substance in dairy cows can be well evaluated from its concentration in the milk
Iodine (Mn=> Faeces, bile)
By giving 4-8x more group vitamin B than normal requirement the mean growth can be improved in
Fattening pigs
One of its deficiency syndromes is opostohonus in lambs
Vitamin B1 (thiamine)
By increasing liginin concentration in the feed
The feed intake decreases, also digestion decreases
For determination of nutrient digestibility by a total collection method
Regulation of the whole 24h long feed
Intake and collection of the faeces are required
Extracted oil seed meals count approximately so much CP
35- 50% (soybean 48%)
Its deficiency syndrome can be fatal
Mg (gracing cow)
BV of a feed can be calculated as follow
Retained N / absorbed N x 100, biological value: proportion of absorbed N that is retained for maintenance of growth
NPO can be calculated as follow
Retained N/ intake N x 100
