hmmm yes i agree. I went crap in my ag 1/2 yearly, 59.5/80. The ag teachers at our school are so picky!! My teacher said that they're heaps pickier than what Hsc markers are...but I guess they're doing us a favour *sighs*

Hey! yeah i know a bit about beef production, i have some really good contacts! haha. na really i have a big booklet on market specifications especially for places like woolworths and what the look for in their meat. If anyone wants any info, i might be able to help, just ask : )

At the moment we are doing sustainable land and resource management, just did grapes and all that. After this i think were gunna do horticulture as an elective, and then agribusiness i think, but not sure?????

I really like ag, some people think its all just farmy and all that, but i think the markets for different products can be very interesting, after all its ag that keeps our exports going...so to all those people who think were just ag dags....theres more to it than that!!! haha!

Has anyone done milk as a product study??

we're doing plant and animal production at the moment. I think we're going to study milk because we had to listen to some dairy farmers guy come and talk about milk production/marketing earlier on in the year and my teacher said something about needing it later. Anyway, I have some notes on the talk so if you want I can go dig them up.

I like ag too! It involves so much more than what most people think it does. I find most of it really interesting. Ag dags........pfft

ok, well...i think NAR = the dry matter production take away the maintenance needs for growth??? i think thats a bit dodgey, but something like that...ill check the text book and get back to u! lol


ok next question....what the is major difference between the way that ruminants make protein and the way monogastrics do?

NAR=photosynthesis - respiration.....it looks the same as what you said

um.....well monogastrics aren't capable of making their own protein (or am i confusing this with something else....?) so they need it supplied in their diet. The microorganisms in the rumen of ruminant animals is able to make microbial protein.....

What are the advantages and disadvantages of using native grass species in a pasture system?

ok...well


1) advantage...they generally tolerate australias harsh environment in many cases, they are able to withstand dry climatic conditions and little water.
1) disadvantage...they are in many cases not as productive as introduced species, and therefore cannot meet the energy requirements of some animals eg. dairy cattle need high protein and energy.


next question...Explain one advantage and one disadvantage of genetic modification in a specific crop

Um....i'm not really sure on this one.....feel free to correct me or add any details ive missed...

Bt cotton:
advantage- reduces the need for pesticides which is better for the environment (less chemicals end up in water ways from run off etc), um .....economical (no need to spend money on pesticides)
disadvantage- ineffective when pests become resistant to chemical (??)

next q.....identify products obtained from milk

AG's one of the easiest subjects to study for. I just did notes for every point on the syllabus and did plenty of past papers. The questions you'll find tend to be pretty typical...

yeah they seem to recycle questions a bit. I did some practice papers and came across the same questions in several of the papers.

hey smiley, to your questions, name to inputs and out puts of your product.
If your talkin bout milk, then to inputs would be feed and veternary checks, and two outputs would be milk and milk by products such as yoghurt, butter etc.
If your product isn't milk, then can i ask, what is it??????
Jaydels, bout your Bt cotton advantages and disadvantages, your spot on, but the whole point of "Bollgard" as it is now called is to reduce resistance towards pesticides. But it is true, if the pest becomes resistant, then there is little protection for the crop against cotton pests. Another advantage is a reintroduction of biodiversity, as the pests that removed the biological pests in the first place will return because there is reduced competition.
if anyone else has any questions, let me no and we'll brain storm an answer i'm sure.
anyway, hope to hear from you smiley, have a good one, cheers, Elizabeth xoxoxo
