RESUMEN.- La agricultura extensiva en Uruguay es la actividad que utiliza la mayor parte de los herbicidas comercializados en el país, siendo la soja el principal cultivo agrícola. La evolución de malezas resistentes a herbicidas ha implicado, de modo general, un aumento del uso de estos productos. El objetivo del trabajo fue evaluar diferentes densidades de avena y centeno sembradas previo a la cosecha de soja en combinación con diferentes métodos de terminación (Químico "Q", rolado "R" o químico reducido + rolado "QR") sobre el enmalezamiento y rendimiento en el cultivo de soja siguiente. --------------- SUMMARY.- Extensive agriculture in Uruguay utilizes the majority of herbicides marketed in the country, with soybean being the main agricultural crop. The evolution of herbicide resistant weeds has generally led to an increase in the use of these products. The
objective of this study was to evaluate different densities of oats and rye sown prior to soybean harvest, combined with different termination methods (chemical "C" rolling "R", or reduced chemical + rolling "CR"), on weed infestation and yield in the following soybean crop. |

The association between genetic resistance of lambs to gastrointestinal parasites (GIP) with dry matter intake (DMI) average daily gain (ADG) and residual feed intake (RFI) was studied. Sixty-four Corriedale lambs (357±14 days old), from divergent lines for resistance to GIP (27 resistant-R and 37 susceptible-S) developed by the Uruguayan Wool Secretariat were used. The animals were allotted to one of five outdoor pens, they were stratified by sex, body weight, and sire. Each pen was equipped with five automated feeding systems and two automatic weighing platforms allowing individual records of feed intake and body weight. After 14 days of acclimatization to diet (ad libitum Lucerne silage: DM 36.5%, CP 21.7%, ME 2.51%) and feeding system, two tests were run over two periods of 44 (P1) and 42 days (P2), respectively. Firstly, the animals were maintained worm-free (P1) followed by an artificial
infestation of Haemonchus contortus (P2). The infestation occurred in three consecutive days with 2,000 L3 larvae per day. The second period was split into two subperiods from 0-23 and 24-42 days post infestation (P2a and P2b, respectively). Records for faecal egg count (FEC) were taken in days 9, 23, 27, 30, 42 post infestation. The DMI (kg/ day) was computed as the average of the individual daily intake, ADG (kg/day) was calculated by regression using
all weights for each period, RFI is the residuals resulting from the model DMI = ADG + metabolic weight (defined as mid-weight for each period ^0.75) + pen (1-5) + type of birth (1 or 2). There were no differences between lines in DMI, ADG, RFI for both periods. However, statically significative differences (P<0.05) were found in P2b for ADG and FEC (at day 23). The R line showed higher ADG than S line (0.132±0.017 vs 0.091±0.014 kg/day) and
lower parasite infestation (1,049 vs 2,479 back-transformed FEC mean). Probably, the high CP diet content and the age of the animals contribute to decreasing the differences in FEC between lines. These preliminary results suggest a difference in growth pattern between R&S lines during the infestation period without effects on DMI.
