Well , my answer is after attended seminar it will not guaranteed u that you would have a successful farm. ( 100% guarantee)
(the above are the house swifts, white rump on the back. )
(swiftlets do not have white rump on its back)
If you don't believe me check it out with those who had attended seminars. You will get the answer. Attending seminars is to learn the basic there are no secret blue print farm's design or secret technique revealed. Even it does , imagine how many people had already attended the same seminar and how many had shared the same secret and even if it is a secret, it has no longer considered a secret as too people had knew it.
Well if you want to know the basic of swiflet farming then it is good to attend seminars or to get some certificates which enable you to apply license from the council but then again it would also no guarantee that you would get the license easily.
Most seminars teach the very basic of Swiftlet farming which are : the temp of 26-30dg , Rh 85%, differences of house swifts & swiftlets ..blar..blar..which most you could get it from books, I mean selected good books, not all books are relevant some are too basic and some contradict with the basic theories. Only few selected books are good that actually could enrich you knowledge.
Therefore seminar is good for those who want to know the very basic but beyond that it is all relied on your intelligent and your eagerness to learn and most of all you need a mentor. If you don't have one, look for one. Make sure you find a good knowledgeable one. If your mentor is a half past six then you would ended up the same. " Blind leading the Blind" which is too common now that is why the failed rate of farms is getting higher.
So if you want to attend seminar go ahead but don't expect it to turn you into a SUPER SIFU just after 1 day or a 2 days courses. But there are few who had attend seminars after that thought that they are the King of Sifus........and undertake the construction, design, renovation,etc and ended up having failed farms.
