The objective of this research was to determine the ingestive behavior, volatile fatty acids, and blood biochemical and hormonal variables of goats consuming a diet with 15% glycerin. Feed efficiency (FE) and rumination (ER) of dry matter intake (DMI) and neutral detergent fiber (NDFI) of dairy goats supplemented with glycerin (0 and 15%) were not influenced by treatments (p > 0.05). The specific activities of defecation, urination and drinking had a significant effect (p < 0.05) in relation to the treatments with glycerin in the diet of dairy goats. The occasional activities (defecation, urinating and drinking water) decreased with the addition of 15% of glycerin in the goats' diet. Lactic acid had a significant effect (p < 0.001) with the addition of 15% glycerin. Diets for dairy goats with 15% glycerin did not change the consumption of dry material, neutral detergent fiber, nor did they change the ingestive behavior of these animals. The levels of globulin, protein, albumin/globulin, glucose, cholesterol, urea, triglycerides, cortisol, and T4 variables were significantly influenced (p < 0.05) by the addition of glycerin in the diet.

The purpose of this study was to establish a multivariate model using two complementary multivariate statistical techniques: Factor Analysis and Stepwise Multiple Regression, to predict tissue composition through carcass characteristics of Santa Inês sheep. The data was obtained from 82 Santa Inês sheep under confinement. The predictor variables were carcass characteristics related to weight, yield, morphometric measures and meat cuts. The use of latent variables from factor analysis in multiple regression models eliminates the problem of multicollinearity of the explanatory variables, improving the accuracy of interpretation of results by proposing a better fit of the mathematical model. However, the coefficient of determination (R²) values were moderate for muscle proportion and total fat, and low for bone proportion, indicating that more appropriate independent variables should be used to better predict the proportion of tissues in Santa Inês sheep.

The objective was to contribute to the characterization of apiculture in the State of Paraíba, to verify the physicochemical quality of honey produced in the region and influence of the type of packaging used in honey quality. The data were obtained through a qualitative approach with semi-structured questionnaire and interviews with the rural owners. We interviewed 30 beekeepers from the municipalities of Bananeiras, Dona Inês and Solânea. 18 samples of honey were obtained for physicochemical analysis. It was observed that beekeeping is characterized as a secondary and family-based activity, through small fixed apiaries (86.67%), with 5 to 20 hives (53.33%), except Bananeiras, which have 21 to 40 hives (60%). An annual harvest is carried out (43.33%), with production above 100 liters (46.67%). Apiculture pasture is considered good, according to beekeepers, in diversity and numbers of individuals (56.67%), 30% provide artificial feeding to the exams. As limiting factors were the climate (93.33%) and labor (6.67%). Regarding the physical-chemical quality of the honey, it was observed average values: 3.45 for pH; 29.34 meq / kg for acidity; 0.64 Aw for water activity; 21.07% for moisture; 0.25% for ash and for total, reducing and non-reducing sugars of 70.54, 58.55 and 12.01%, respectively. The type of container used for the storage of honey did not influence its physico-chemical qualities. The data obtained demonstrate the potential for the development of beekeeping in the region, but requires technical investment to expand this economic activity. Honey samples meet most of the prerequisites established by Brazilian legislation, except for moisture and reducing and nonreducing sugars for some samples analyzed. [ABSTRACT FROM AUTHOR]
