ABSTRACT The objective with this research was to compare milk quality parameters among herds characterized by different levels of milk production. The research involved 1080 bulk milk samples collected from 30 dairy herds, which produce milk for Parmigiano Reggiano cheese, during three years. Each milk sample was analysed for fat, crude protein, titratable acidity, total bacterial count, somatic cells, coliform bacteria, and Clostridia spores. Least mean values were obtained by ANOVA using milk production intervals from 6000 to 7999 (L-group), […]

ABSTRACT The objective of this study was to evaluate milk quality for somatic cell count (SCC) analysis and total bacterial count (TBC) in agroecological production systems and conventional systems, relating them to the frequency of milking practices and types of facilities. The study was conducted in 2013 and 2014, in the western region of Paraná State, Brazil. We used a semi-structured questionnaire to identify management practices of producers in the 17 dairy systems (DS) in the city of Diamante d’Oeste […]

It was evaluated the effects of using milk protein or supplemental zinc in the diet on performance, relative weights of small intestine and liver, intestine morphology and IGF-I (insulin-like growth factor) serum concentrations, growth hormone and zinc in piglets. The experiment lasted 14 days and it was carried out using 60 piglets weaned at 21 days of age (5.43 ± 0.46 kg) in a complete random design, in a 2 x 2 factorial composed of two levels of milk protein […]
