The incorporation of the male category Holando fattening systems, can provide the market with lean meat with organoleptic characteristics differentials. Background Studies in the EEA C. of Uruguay, have shown that Holstein calves slaughtered with the maximum permissible media res (74kg) weight, may be incorporated into the category of job “calf consumption” good acceptance in the local market (IPCVA, 2011). Through proper management and use of rations “zero fiber” is possible.

In the province of La Pampa, there is a dairy basin producing a large number of male calves Holando, so that category of animals is an interesting resource for pampeanos producers. For this reason, was conducted between technicians of the EEA Concepcion del Uruguay INTA and Extension Unit and Territorial Development INTA in General Pico, together with professionals from the private sector, a trial for 167 days in a feedlot, using 30 Holstein calves belonging to business premises “La Luisa” in the town of Quemú Quemú province of La Pampa.
The objective of this work was to evaluate the functioning of the protected urea (UP) in concentrated diets ad libitum without inclusion of fiber for category Holando males through the measurement of production, such as weight gain, consumption, feed conversion components and observing the characteristics of the carcass through ultrasound. Rations were formulated based on corn grain, with the addition of UP (262% crude protein; PB) or a protein concentrate (35% CP) for protein correction. Animals assessment and control group, presented daily liveweight gains (daily gain) that were in the order of 1.3 kg of PV. After the experience, the evaluation group animals reached the target slaughter (& gt; 360kg) weight as those fed a control diet with a source of true protein. It was found that it is possible to include small amounts UP (100140g) as a replacement for other sources of true protein concentrate diets to correct whole corn grain base. Using the ability of ruminants to grow and develop through the use of microbial protein synthesized from non-protein nitrogen and rumen degradable energy.
