This study evaluated the effect of crude protein (CP) reduction in four diets (156, 139, 132, and 127 g Kg-1 DM) maintaining constant metabolizable protein (188 g/day) on the follicular fluid and cumulus-oocyte complexes of mid-lactating Girolando cows. Twenty-two Girolando cows with average of 21.55 ±3.19 L daily milk yield, 105.30 ±22.62 days in lactation and 3.22 ±0.03 body condition score were selected. To reduce CP in diets and maintain constant metabolizable protein, urea and soybean meal were gradually replaced by lignosulfonate-treated soybean meal (SoyPass®, Cargill), resulting in an increase in rumenundegradable protein and a reduction in rumen degradable protein. A linear and quadratic reduction was observed in the plasma and follicular fluid urea nitrogen concentration following CP reduction, with the most intense reduction occurring in the 127 g Kg-1 DM group (p<0.001). As CP reduced, there was a tendency for a linear increase in the follicular growth rate (P=0.0696), on the number and proportion of viable oocytes (P<0.09), and also a linear increase for the number (P=0.0397) and proportion (P<0.09) of grade I viable oocytes. Plus, there was a linear effect for the number of cumulus oophorus cells. Cows fed with the lowest amount of CP had cumulus-oocyte complexes with higher numbers of cumulus oophorus cells (P=0.0238). Also, the reduction of diet crude protein was followed by a decrease in the probability of oocytes? DNA degradation. In conclusion, the reduction of CP in the diet of mid-lactating Girolando cows, reduces urea nitrogen concentration in both blood plasma and follicular fluid, and, as a consequence, increases the viability of oocytes and the number of cumulus oophorus cells while reducing oocytes? DNA degradation of follicular included cumulus-oocyte complex. The reduction on dietary CP may improve in vivo oocytes-embryo development impacting fertility of lactating dairy cows.

This study aimed to evaluate the performance and characteristics of the grapes as subsidies to the recommendation of new wine grape cultivars for the São Francisco Valley. An experiment was carried out in Petrolina, Pernambuco state, during four seasons in 2014 and 2015 and the treatments were represented by 10 cultivars and three breeding selections: Grenache, Tempranillo, Merlot, Cabernet Sauvignon, Malbec, Petit Verdot and Syrah for red wines and Sauvignon Blanc, Chardonnay, Chenin Blanc and breeding selections 46, 14 and 47 for white wines. The experimental design was a randomized block with four replicates and two useful plants per plot. The following variables were evaluated: sprouting, bud fertility rate, Ravaz index, production, number of clusters, weight, length and width of cluster, weight and volume of 100 berries, soluble solids and titratable acidity. A better balance between production and vigour was obtained in Grenache, Merlot and Tempranillo cultivars, presenting values of 7.56, 6.50 and 5.93, respectively, for Ravaz index. Grenache, Chenin Blanc and Tempranillo were the most productive cultivars with average yields estimated at 10.4, 8.7 and 8.4 ton/ha/season. Selection 14 had longer, wider and less compact clusters, which can reduce clusters rottenness. The percentage of sprouting ranged from 38.13% in selection 14 to 77.6% in cv. Chenin Blanc. The average index of bud fertility was 0.79 cluster/bud, with no significant differences among cultivars. Greater potential for sugar accumulation was found in the selections 14, 46 and 47, while the titratable acidity ranged from 0.63% in cv. Merlot to 0.89% in selection 47. Grenache and Tempranillo have showed potential to obtain adequate yield and balanced vines, while Sauvignon Blanc, Chardonnay, Cabernet Sauvignon, Malbec and Petit Verdot presented low yield being necessary to select clones more productive and well adapted to the tropical conditions. Further information about the quality of grapes and wines should be added to these results to allow the recommendation of new cultivars or breeding selections of wine grapes for the São Francisco Valley.
