I know that fibre is very important in dairy rations, but does it really mean more money in my pocket?

Kenneth Botha, technical adviser at Barnlab, replies:

Fibre in dairy rations are important for a number of reasons, among others to optimise rumen function and prevent acidosis, and to stabilise pH in the rumen. A high producing cow easily digests 11kg of roughage on a dry matter basis. Fibre is one of the nutrients in this roughage.

If we can predict intake more accurately, we can formulate the ration more precisely. This will also have an effect on roughage production, because if this aspect can be improved, the farmer will require less concentrate. The result is a healthier cow producing well from more self-produced feed and fewer purchased feed sources. It will have a major impact on the farmer’s pocket.

Ek is bekommerd oor my weiveld na die droogte. Daar is groot kolle kaal grond en my buurman sê die kans vir giftige plante om daar wortel te skiet, is goed.

Dr Danie Odendaal, direkteur van Veearts Netwerk, antwoord:

Ja, ongelukkig bied die droogte die ideale omstandighede vir gifplante en onkruid om as primêre bedekking te floreer. Die groot probleem met gifplante is dat daar in baie gevalle nie ‘n behandeling bestaan as die dier reeds vergiftig is nie. Hou veral jou krale of houkampe dop, want dit is sulke areas waar die grond versteur word, wat ‘n ideale teelaarde vir gifplante skep.

Plante soos goor- of gifappel, melkbos, lantana en nastergal moet alles fyn dopgehou en uitgeroei word. Gifplante is landwyd aan die toeneem.
