Purpose Animal production wastes are promising for use in agricultural production as a plant nutrient or soil conditioner. However, if not properly managed, they can contaminate the soil and plants, resulting in public health risks. Considering that the composting technique is recommended to ensure compost hygiene and agronomic viability, the present study aimed to evaluate the microbiological and parasitic load during the composting of residues from conventional and organic animal productions. Method The presence of Salmonella sp. and/or helminth eggs and the quantification of thermotolerant coliforms were determined in horse bedding and organic and conventional poultry litter during the process of composting. Results The initial load of thermotolerant coliforms was greater than 1017 MPN g-1 in the three raw materials. All of them showed a significant reduction in these bacteria at the end of the composting process, reaching 99.98%, 100.00%, and 99.80% in the horse bedding, organic poultry litter, and conventional poultry litter, respectively. All the fresh residues contained helminth eggs, with the horse bedding exhibiting the highest amount compared to the others. However, they all revealed an absence of helminth eggs at the end of the composting process. Salmonella sp. was absent in both the raw materials and the final compost. Conclusion Composting was effective in eliminating helminth eggs and reducing thermotolerant coliform levels. However, the final composts retained a higher pathogenic microbial load than that required by the current Brazilian legislation for use in agriculture.

Abstract: Milk production traits, milk composition and somatic cell count (SCC) from exotic dairy goats were characterized in tropical climate using data from Dairy Goats Breeding Program. The breeds analyzed are distributed in two regions of Brazil (Southeast and Northeast). The Alpine, Saanen and Toggenburg (raised in Southeast) breeds were compared among themselves and with the breeds of Northeast (Anglo Nubian and Saanen). This study demonstrated that milk yield, 305-day lactation yield, lactation length and daily milk yield were influenced by the genetic of animal (breed) and the environmental conditions, such as flock, month and year of production. These same effects affected the milk composition and SCC which also were influenced by physiological stages of the does (lactation and test-day milk order). There were differences in milk composition between the breeds. This may be a result of diet and chemical composition of the pasture feeding the animals, as well as others genetic and environmental factors. The global averages for proportion of lactose were below of the minimum limits established by the Brazilian Ministry of Agriculture, Livestock and Food Supply. The average of SCC was above one million of cells/mL. This study is the first work of characterization of exotic breeds in tropical climate with a database derived of official milk recording. |
