Most important protein supplement, all others are compared to this one - Correct Answer
Soybean Meal (SBM)
second most important protein supplement, and what is the toxin associated with it? - Correct
Answer Cottonseed meal (CSM)- associated with toxin gossypol
Which anti-nutritive factor is contained in Soybeans, and therefore they must be heated to
destroy this? - Correct Answer Trypsin inhibitor
Protein feed derived from slaughterhouse waste, is high in collagen, and is a concern because of
"mad cow" disease - Correct Answer Meat meal (meat and bone)
Protein source collected from the kill floor of slaughter plants, contains 80%+ CP, is high in lysine
but severely deficient in isoleucine. It has low digestibility due to the drying process and
therefore is a good source of rumen undegradable protein to ruminants - Correct Answer
Blood meal
What are the types of NPN discussed in class? - Correct Answer -->Urea- most common source
for ruminants
-->Biuret- 2 molecules of urea that have been condensed
--> Dried poultry waste
Mycotoxin in corn - Correct Answer toxins elaborated by molds (fungi) growing in or on
feedstuffs
Mycotoxins in peanuts - Correct Answer -->susceptible to aflatoxins
-->"hogging off": earlier practice in swine, produces soft pork due to unsaturated oil
consumption
, -->don't feed fat peanuts for several weeks before slaughter
What is rumen undegradable protein, why would we feed it, what are some sources? - Correct
Answer -->insoluble proteins that escape/bypass the rumen
-->should feed it to growing/lactating ruminants to help meet the higher protein requirements
to supply AA, for adult ruminants for maintenance and for protecting feedstuff protein from
ruminal degradation
-->sources-?
What is RUP? - Correct Answer Rumen undegradable protein
What are some methods to make RUP from degradable protein sources? - Correct Answer --
>Heat treatment
-->Coat protein w/fat
-->Treatment w/tannins
Why would we feed RUP? - Correct Answer Growing or lactating ruminants: higher protein
requirements to supply amino acids for muscle growth and milk production
