The objective of this experiment was to evaluate the effects of microbial inoculants on the reduced concentration of gases and effluent, dry matter recovery, pH, volatile fatty acids, and chemical composition of orange pulp silage, using a completely randomized design, with four treatments and four replicates per treatment. The treatments were: orange pulp silage (CONT), citrus pulp silage + Lactobacillus plantarum (LAC), citrus pulp silage + Lactobacillus buchneri (BUCH), citrus pulp silage + Lactobacillus plantarum and buchneri (LACBUCH). Inoculants were applied at a rate of 25 liters of solution per ton of citrus pulp containing 1×103 CFU respectively of Lactobacillus plantarum and Lactobacillus buchneri per gram of silage. There was no effect of the usage of different inoculants on the reduction of gas and effluent, as well as the pH of the silage. The dry matter (DM), crude protein (CP), non-fibrous carbohydrate (NFC), mineral matter (MM), ether extract (EE) and the profile of fatty acids did not change significantly with the inclusion of the inoculants. The contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were higher for silage with Lactobacillus buchneri compared to control. The administration of microbial inoculants in orange pulp silage did not result in benefits relative to the dry matter losses during ensiling or the nutritional components. Source

The objective of this study was to evaluate the effect of a diet supplementation with 500mg organic zinc (Zn) on sperm morphological characteristics (mass motility, individual motility, and sperm livability) as well as minor and major sperm defects in Nelore bulls during the dry season of 2010, the pluviometric precipitation during the experimental period which occurred from April to October, was 69mm from April to August. Thirty-six bulls were selected and divided into two groups of 18 bulls. They were fed the supplemented diet for 180 days. The animals in the first group (G1) were supplemented with an average of 48,89ppm/kg MS Zn, and the animals in the second group (G2) were supplemented with 115,09ppm/ kg DM Zn. Data was analyzed with Minitab 13.0. The results of the morphological characteristic of sperm G1 and G2 were higher at 180 days compared to Day zero, especially in vigor and mass motility, with only statistically significant difference in each group, not differentiating between groups. The organic zinc did not affect the morphological characteristic of sperm in Nellore bulls in the dry season. Source
