PRODUCTIVE PERFORMANCE OF LAMBS OF DIFFERENT GENOTYPE UNDER A FEEDLOT SYSTEM
The objective was to evaluate the effect of the genotype of lambs on the stockyard finalization in the Northwest of the province of Corrientes, Argentina conditions. The experiment was carried out at the Experimental Station Farming (EEA) of the Institute National Agricultural Technology (INTA) Corrientes, Argentina. Used 30 lambs (Santa Inés = 12; Dorper x Romney = 12; and Creole = 6), with an average live weight of 20,1 kg, distributed in five pens. The lambs received a diet based on 40% expel sunflower - 60% whole corn grain and fiber was provided by Rhodes grass hay. In addition, they had water and mineral salt ad libitum. We used a completely randomized design; we studied daily gain of live weight (GDPV), the total gain of live weight (GTPV), daily consumption by pen (CDC) and feed conversion (CAC) for pen. The genotypes were significantly different (P<0,05) in GDPV, GTPV, CDC and CAC. The average general were 0,14 kg.day-1, 9,62 kg, 7,19 kg MS-1 and 8,62 kg MS.meat-1 kg for GDPV, GTPV, CDC, and CAC, respectively. It is concluded that hair breeds (SI and DR) were more efficient.
