Die invloed van aantal kampe en veegetalle op diereproduksie en veld toestand

Uittreksel

Vier wisselweidingstelsels met 3, 6, 12 en 18 kampe per kudde wat varieer van stadige seisoensbeweiding tot vinnige wisselweiding, is onder ‘n ligte (of normale) en swaar belading vanaf 1967 vir sewe jaar vy die Landbounavorsingsinstituut, Glen uitgevoer, Diereproduksie van merino‐hamels en veldtoestand is gemonitor. Geen duidelike tendense kon verkry word tussen die aantal kampe nie maar hoër produksie per dier is by die ligte belading verkry maar nie per hektaar nie. Veld wat in ‘n goeie toestand is kan volgens enige veldbestuurmetode teen die korrekte belading bewei word mits die rusperiode voldoende is. Dieselfde tendense is by die lewendige massa, wol‐ en karkasmassa gevind.

Abstract

Four grazing systems with 3, 6, 12 and 13 paddocks per flock which vary from a slow season based grazing pattern to a quick rotational system, with a moderate heavy stocking rate were conducted at Glen Agricultural Research Institute for seven years, started in 1967. Animal production of Merino wethers and veld condition were the main measurements. No definite trend could be found between the number of camps but higher production per animal was obtained with the moderate stocking rate, but not per ha. Veld in good condition can be grazed according to any veld management system at the correct stock rig rate as long as the rest period is sufficient. The same tendency was obtained with the liveweight.
