The results of a fattening trial with steers covering the weight range 300 kg LW to optimum fatness score were used for an economic analysis comparing the breeds Angus (AN), Simmental (SI), Charolais (CH), Limousin (LI), Blonde d’Aquitaine (BL) and Piemontese (PI). More than 95 % of margin variations are attributed to differences in purchasing costs and produce of sales. Factors of success are: dressing percentage, carcass conformation, and matching the degree of precocity with the feeding intensity such that growth is optimized within the limits set by the market. Under the conditions of the trial, the LI and CH breeds realized the best combination of the factors determining the economic result. Thus, they reached the highest comparable margin per large animal pen unit. There is evidence for better returns for the early maturing breeds AN and SI when maximizing the slaughter weight. The economic result of the late maturing breeds BL and PI can be improved. The corresponding possibilities are presented in part 2.

In both sport and alternative agriculture, horses are once again being used as draught animals. Efficient power transmission plays an important role in the wellbeing of draught horses.
A study by Vetsuisse shows that the outdoor veal calf concept reduces antibiotic consumption in calf fattening by 80%. AGRIDEA has examined the economic viability of outdoor veal calf production and concludes that it cannot compete with conventional veal calf fattening.
In contrast to pigs, dairy cattle are as yet rarely fed protein-reduced diets. Studies show that there is also potential for protein savings in cattle, and thus for reducing ammonia emissions.
