Currently in Uruguay, several experiments of crossbreeding and synthetic breeds are being developed with the inclusion of East Friesian (EF), Finnsheep (F) and Texel (T) meat breeds. The milk production and udder morphology of 57 ewes (8 F, 24 EF and 25 T breeds) from three flocks were evaluated. A total of 161 records (24 F, 68 EF and 69 T breeds) were collected in three test-day controls with average days in milk (DIM) 21, 40 and 60. The ewes were
randomly assigned to four experimental groups and separated from the lambs during 4 hours in a good pasture. Before that, it was allowed the nursing of the lambs and the ewes were manual milked to empty their udders. Glandular cistern area (CA) were recorded by ultrasonography (from the side area of the udder) after intramuscular injection of 1 I.U. of synthetic oxytocin, followed by mechanic milking to record the milk weight (MW) and quality (protein-P% and fat-F% percentages). All the traits were adjusted for the effects age of the ewe (1-3), type of lambing (1-2), breed (F, EF, T) and DIM and the square of DIM (both as covariables). Correlation between the residuals of CA and MW from these models were computed. EF showed a wider CA (35.7±2.0 cm2) than F (25.0±3.4) and T (28.4±2.6 cm2) breeds. This was expected because EF is a dairy breed selected to be tolerant to long milking intervals. However, no differences (P>0.05) were observed for milk production (F 382±47; EF 430±29; T 392±37 ml). The F and T breeds showed higher (P<0.0001) P% (5.6±0.1 and 5.6±0.1%, respectively) than EF (4.9±0.1%) and the similar (P>0.05) F% (7.0±0.4; 6.9±0.3 and 6.5±0.2, respectively). The correlation between CA and MW residuals were 0.48 F, 0.42 T and zero (P>0.05) for EF breeds. These findings would indicate a greater proportion of alveolar production in the EF breed and/or a better response to the release of milk by the oxytocin injection than the non-dairy breeds. Though, further research would help to determine the breed?s differences between milk production and quality, as their conversion into kilograms of lambs weaned.

ABSTRACT.
The goal of our study was to improve 'Tannat' grape and wine composition, by achieving vine balance. We evaluated a new grape-growing paradigm for Uruguayan conditions that include unpredictable periods of water deficit or excess in nonirrigated vineyards and eliminates competition from cover crops. We used undertrellis cover crops (UTCC) to limit vine water availability, reduce vine growth rate and final canopy size. However, to avoid excessive vine water stress due to the UTCC competition, irrigation was used during water deficit periods. This strategy was tested in combination with variable planting density to optimize vine vigor control in our environment over two growing seasons in southern Uruguay. Two factors were evaluated in a split-split plot experiment with five replicates. Treatments were: UTCC (full cover of the vineyard soil with tall fescue) versus conventional alleyway tall fescue with 1.0 m wide weed-free strip under the trellis, and two spacings between vines (0.8 vs. 1.5 m). Deficit drip irrigation was provided at mid-day stem water potential (SWP) thresholds of -0.9 MPa early and -1.1 MPa later in season. Shoot growth rate, SWP, berry size and berry composition (Brix, organic acids, total anthocyanin) were monitored over the season as well as final yield, cluster and pruning weights. Preliminary results showed that UTCC regulated vine vegetative growth and final canopy size, reduced berry size, cluster weight and bunch-rot incidence as well as increased tartaric/malic ratio, Brix and anthocyanin concentration in grapes. The combination of UTCC and 1.5 m inter-row spacing led to below-optimal shoot growth. The use of such multiple techniques shows promise for achieving vine balance in high-capacity conditions.
