These are feeds which are marked with the message ‘Beneficial effect on health without residue building’. Give an example:
Nutraceuticals ! Amino acids, vitamin, and mineral supplements, fish, oil, garlic, ginseng.
For this animal, its roughage requirement is at least 0.5kg/100kg BW:
Horse
Extracted oilseed meals contain approximately how much CP?
35-50%
Soybean ! ~45%
Could milk be described as bulky with low DM content?
Yes
What are the possible methods for heat treatment?
Hydro-thermic (autoclaving, flaking, wet extrusion, wet expandation, toasting) Dry thermic (air, pulverization, direct drying, dry extrusion, dry expandation, micronasation, cooking via microwave, roasting)
What is the protein requirement of pig?
33%
What is the energy protein content measurement unit in different species?
DE - Horse, Pigs, Rabbit
ME - Poultry
NE - Cattle, Sheep
What is the consequence of animal-derived feed?
BSE, MFD, Swine fever, salmonellosis, camplobacterios, listeriosis, E. coli ! Hence prohibited
for food-producing animals
What is a good pH for silage?
4 – 4.2
Continuous grazing is less effective than: A. Rotational grazing B. Strip grazing C. Both of them D. Neither of them
Both of them (A+B)
Rotational grazing. Strip grazing
Liberation of ammonia during heat processing of feeds indicates that there are:
Reactions between protein molecules
If the quality of corn silage is good, it contains this acid:
Lactic acid
Its crude fiber content is usually higher than 20% in: A. Meadow hay B. Alfalfa hay C. Both of them D. Neither of them
Both of them (A+B)
Meadow hay. Alfalfa hay
The Substitution Number (SN) of corn is 0.3. it means, that by adding 1kg DM of corn to the forage, the DM intake from the forage is:
Decreases by 0.3kg
Its Crude Protein content is between 20 and 30% on DM basis:
Green alfalfa
If the by-pass category of a feedstuff is low, it means most of its protein content:
Will be degraded in the rumen
Its protein requirement in the practice may be expressed in crude protein:
Laying duck
By increasing the lignin content of the feeds:
The feed intake decreases
For determination of the nutrients’ digestibility by a total collection method:
Registration of the feed intake and collection of the faeces are required
The approximate Dry Matter content of fresh pasture grass is:
20-25%
It published feeding recommendations:
ARC
The effect of feeding protein according to the ARC (1984) and NRC (1989) recommendations
Its most important anti-nutritive factors are saponins:
Alfalfa
Bulky feeds have:
Low Dry Matter content related to the whole volume
e.g. Roughages
To the over-heating of feeds, this amino acid is the most sensitive one:
Lys
