Data for the production of alfalfa( Reference Mathews, Canevari and Frate 51 , Reference Vargas, Mueller and Frate 52 ) and maize( Reference Vargas, Frate and Mathews 53 , Reference Brittan, Muiner and Klonsky 54 ) used for animal feed were obtained from CRS and were added to the direct water used by the animals using a net feed consumption rate of 5·62 kg maize/kg beef and 2·66 kg alfalfa/kg beef. A feed conversion efficiency of 7·0 was assumed( Reference Horrigan, Lawrence and Walker 10 ). Soya in the feed formulations for beef and poultry was excluded.
since most beef cattle graze for the first year, where they put on the majority of their weight, then why would you attribute all the meat production to feedlots? shouldn’t it be halved at least?
