Male calves from Friesian dairy herds in Israel are fattened for meat up to age 12 to 14 weeks on feed concentrate, but their feed conversion is only 5.5 to 6.5, compared with 4.5 to 4.8 in Europe. In Austria 23 male Israeli calves weighing 24 kg were fed on low-energy pelleted dry feed with only 2.2 Mcal/kg and 13.1% protein. Two of the rations were identical, except that one had been prepared in Israel; the third ration had maize and maize cob meal replaced by cottonseed husk meal and sugar beet chips, and the fourth had only the maize cob meal replaced in that way. There was no difference in fattening performance, except that the cattle given the feed prepared in Israel put on slightly more fat, and the crude fibre replacement by cottonseed husks resulted in insignificantly higher daily weight gains than those obtained with maize cob meal. All the feeds were 10 to 15% cheaper than the usual feed concentrate and resulted in 11% better feed conversion.
