Proteïenbronne in die rantsoene van groeiende varke 2. 'n vergelyking tussen vismeel en karkasmeel

Abstract

Ses-en-dertig Landras x Grootwit-varkies is aan drie proefbehandelings onderwerp. Vismeel is gedeeltelik met onderskeidelik 0,0%, 5,6% en 11,0% karkasmeel as proteïenbronne in die drie proefrantsoene vervang. 'n Neiging tot swakker groei en 'n betekenisvol swakker voeromset is verkry waar 11,0% karkasmeel in die rantsoen voorsien is. Die insluiting van karkasmeel op die bogenoemde peile het egter geen betekenisvoUe invloed op die fisiese en chemiese samestelling van die karkasse gehad nie.

English Title: Protein sources in the diets of growing pigs: 2. a comparison between fish meal and carcass meal

English Abstract

Thirty-six weaner Landrace x Large White crossbred pigs were used in an experiment conducted to determine to what extent fish meal can be replaced by carcass meal as a protein supplement in pig growth diets. The experimental treatments consisted of three diets in which fish meal was partially replaced on a protein basis by 0,0%, 5,6% or 11,0% carcass meal. The inclusion of 11,0% carcass meal resulted in a slight reduction in growth rate but in a significant reduction in feed conversion. The physical as well as the chemical composition of the carcasses was unaffected by the treatments imposed.
