    The stated goal in this study was to evaluate the behavior in dairy goats Saanen and Alpine during the Fall-Winter, as well as the influence of the number of labor in production and milk quality, low semi feedlot conditions. The research was conducted in two phases, the first was held at the ranch "Las Cabrillas", located in the community of San Juan Chilateca, Oaxaca. The second phase was the chemical analysis was performed in the laboratory of dairy , Institute of Agricultural Sciences (ICAP ), belonging to the Universidad Autónoma del Estado de Hidalgo (UAEH ). The variables were: milk production and milk quality: the results obtained with the Milkscam were: Fat (% ), non-fat solids (%) Density (kg/m3), Protein (%) Lactose (%) Total Solids (%), and pH. Statistical analysis was an experimental design factors using the SAS statistical package The System 9. Females Alpine phenotype obtained the highest parameters of the second to fifth birth delivery, with a best result of third birth as production (2,490 kg) , lactose (5.07 %) and density (1030.732  kg/m3 ). Phenotype Saanen females obtained the highest parameters in the fourth. Higher Fall parameters were obtained , where most of the flock is drying and therefore production and elements decreases as fat (4045 %) , protein (2.777 %) , total solids (0.706 % ) and solids increases no fatty (7.381 %)

    We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at â\u88\u9asNN = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-pT) charged hadron trigger. Jets are measured using collinear-safe jet reconstruction with infrared cutoff for jet constituents of 0.15 GeV, for jet resolution parameters R = 0.2, 0.4 and 0.5. Underlying event background is corrected at the event-ensemble level, without imposing bias on the jet population. Recoil jet spectra are reported in the range 20 T,jetch < 100 GeV. Reference distributions for pp collisions at â\u88\u9as = 2.76TeV are calculated using Monte Carlo and NLO pQCD methods, which are validated by comparing with measurements in pp collisions at â\u88\u9as = 7TeV. The recoil jet yield in central Pb-Pb collisions is found to be suppressed relative to that in pp collisions. No significant medium-induced broadening of the intra-jet energy profile is observed within 0.5 radians relative to the recoil jet axis. The angular distribution of the recoil jet yield relative to the trigger axis is found to be similar in central Pb-Pb and pp collisions, with no significant medium-induced acoplanarity observed. Large-angle jet deflection, which may provide a direct probe of the nature of the quasi-particles in hot QCD matter, is explored
