The objective of this work was to analyze the most appropriate management to achieve higher productivity for carioca beans (phaseolus vulgaris) and pearll cultivar. The research was developed in the Demonstrative and Experimental Area of Irrigation (ADEI) of FCAV/UNESP, Campus of Jaboticabal, SP. Four treatments were used: T1- irrigation with base in ETo estimated by the method of Class A pan; T2- irrigations based on the readings of tensiometers installed at 0,20 m and 0,40 m of depth; T3- irrigations carried out with base in ETo estimated by the method of Penman-Monteith and T4- witness. The results were submitted to analysis of variance. To compare the averages the test Turkey was used at 5% of probability. The treatment T3 had smaller applied water depth than the treatments T1 and T2, and also smaller productivity. The conclusion is that the treatments irrigated with larger frequency showed higher production of grains.

The aim of this study was to evaluate the effects of yeast cell wall extract (YCW) in dry diet on the fecal microbiota, concentration of short-chain fatty acids (SCFA) and on the odor reduction of cats feces. We used 20 animals of both sexes, randomly assigned to four treatments and five repetitions totaling 20 experimental units: 1) dry commercial diet (control); 2) control + 0.2%, 3) control + 0.4%, and 4) control + 0.6% of YCW in dry matter. Enterobacteriaceae and lactic acid bacteria, fecal concentration of acetic, propionic and butyric acids, ammonia nitrogen and sensory panel were performed. There were no significant differences (p> 0.05) for bacterial counts and the concentration of SCFA and ammonia, but in sensory panel a reduction in the odor of feces could be noted with the use of 0.2% of YCW. We concluded that the addition of up to 0.6% YCW had no effect on the microbiology and the concentration of fatty acids, but there is potential for its use as an additive because of the improvement in the odor of feces. However, further studies are needed to understand the mechanisms of action and the effects of prebiotics for domestic cats.
