Resumen: Se monitoreó el ambiente atmosférico y se evaluó el efecto del creep feeding (CF) y del destete temporario (DT) sobre el momento de la concepción y preñez final. Se utilizaron 262 vacas primíparas. El diseño experimental fue completamente al azar. con un arreglo factorial entre DT y CF con afrechillo de arroz o sal comercial. Las vacas madres deterneros suplementados con AA concibieron 15-20 días antes que los demás grupos, pero no se observó diferencia en la preñez final. La eficiencia reproductiva no estuvo asociada a cambios en el peso vivo. la condición corporal ni el DT. Sin embargo. ninguna vaca concibió en un período de 9 días, que coincidió con una ola de calor de 5 días de duración. Concluimos que el CF y el ambiente atmosférico afectan el momento de la concepción en nuestras condiciones. Summary: The effect of climatic conditions, creep feeding (cn and temporary weaning (TW) on the moment of conception and final pregnancy was evaluated. 262 primiparous cows were used. The experimental design was completely random, with a factorial arrangement between TW and CF with rice bran or commercial salt. The cows whose calves were supplemented with AA conceived 15-20 days before the other groups, but no difference was observed in the final pregnancy. Reproductive efficiency was not associated with changes in live weight, body condition or TW. However, no cow conceived in a period of 9 days, which coincided with a 5-day heat wave. We conclude that CF and the atmospheric environment affect the moment of conception in our conditions.

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.
