Graad 4


Module 23


Hoe gereeld eet julle huisgesin hoendervleis of eiers? Waar kom dit vandaan? Hoenderboere kan in twee hoofgroepe verdeel word:

Lêhoenderboere Slaghoenderboere
Definisie Produseer eiers om te verkoop Produseer hoenders wat vir hul vleis geslag word
  • Henne begin lê wanner hul 18 weke oud is.
  • Word in lê-huise aangehou (batterystelsel).
  • Hane en henne om bevrugte eiers te lê.
  • Eiers word in broeiery in broeimasjien geplaas.
  • Hen lê meeste eiers op 20 weke.
  • 26 – 28 weke lae eierproduksie (verkoop).
  • Sommige vryloopstelsel.
  • Tot 50 000 onder een dak.
  • Temperatuur word beheer.
  • Gereeld ingeënt teen
  • Eiers onbevrug.
  • Oor ‘n periode van 52 weke lê ‘n hen ongeveer 300 eiers.
  • Eiers sorteer volgens kwaliteit van dop en grootte.
  • Broei op dag 21 uit.
  • Kuikens teen siektes ingeënt.
  • Kuikens onder verwarmers gehou.
  • Ligte brand vir 16 uur per dag.
  • Kuikens word spesiale kos gevoer om vinnig te groei.
  • Na 40 dae weeg slaghoender ongeveer 2 kg.
  • Gereed vir slag en verpakking.
  • Na winkels versprei (heel of stukke).


Kuikens wat vir teeldoeleindes gebruik word, word op ouderdom 21 weke na ‘n teelafdeling oorgeplaas. Hier word hane en henne saam in een hoenderhuis aangehou (tien henne by een haan). Vanaf die 22ste week word eiers (broei-eiers) in neste gelê. Die eiers word vyf keer per dag versamel. Slegs sommige van die bevrugte eiers word vir teeldoeleindes gebruik. Die hane en henne volg ‘n spesiale dieet en word op ongeveer 64 weke saam met lê-hoenders verkoop.

Waarom is hoendervleis goedkoper as rooivleis?

Aktiwiteit 1

Om in julle groepe die volgende vrae te bespreek en dan terugvoering aan die klas oor die groep se bevindings te gee [lu 1.6, 1.7]

  • Kyk na die skets van die lêhoenders in die battery. Hoe voel jy oor die omstandighede waaronder die hoenders aangehou word?
  • Waarom dink jy word die henne in sulke klein hokkies aangehou?

Wat is “skarrel-” eiers en weglêhoenders?


Leeruitkoms 1: aardrykskundige ondersoek

Die leerder is in staat om ondersoekvaardighede te gebruik om aardrykskundige en omgewingsbegrippe en -prosesse te ondersoek.


Dis duidelik wanneer die leerder

1.6 inligting vanaf kaarte gebruik (insluitend eie waarnemings) om vrae oor mense en plekke te beantwoord (bv. “Waarom is dit so?”) [beantwoord die vraag];

1.7 aardrykskundige en omgewingsbegrippe en -terme gebruik om op verskillende maniere verslag te doen oor ondersoeke [dra die antwoord oor].


Hoendervleis is goedkoper as rooivleis omdat:

Vinniger; korter lewensiklus; min spasie benodig vir teel; geen weiding nodig.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
what is nanomaterials​ and their applications of sensors.

preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
