Abstract: Avaliou-se a variação da produção e qualidade do leite, durante 11 meses do ano através do monitoramento de nove unidades produtoras de leite (UP), escolhidas aleatoriamente por pertencerem à bacia leiteira de Pelotas. Foram realizadas coletas mensais de leite e dos alimentos de cada UP. Foram avaliadas as características físico-químicas e contagem de células somáticas do leite, além da incidência de mastite e a produção média de leite das UP. As UP foram classificadas nos seguintes sistemas de produção: espec… Show more

“…The results obtained for milk fat are different from those found by Martins et al (2006) and Gonzales et al (2004). However, several interactions of nutritional factors can affect the quality and composition of milk fat, such as quantity and quality of the fiber, concentrate level in relation to roughage supplied, location and extent of starch degradation, fatty acid composition and inertia, and ruminal degradability of supplemental fat (Ashes et al, 1997).…”

“…In an experiment carried out in the South of Brazil, Martins et al (2006) found significant differences between the months for protein percentages. The minimum protein values occurred in July and August, and the highest in the months of spring and beginning of summer, coinciding with an improvement of climate conditions and greater availability and quality of pastures.…”

“…A decreased protein content was also observed among milk samples from the other dairy farms (Table 2). although cow's nutrition was not evaluated, the protein index could be related to both the low quality of pastures and decreased dry matter in animals feeding (MaRTINS et al, 2006). average mesophilic bacteria count were in the range 3.4x10 5 to 3.7x10 6 CFU ml -1…”

“…Os autores observaram ponto crioscópico médio maior durante o verão (junho e julho), e menor no inverno (dezembro e janeiro). Martins et al (2006) ao avaliar a variação da produção e a qualidade do leite produzido na bacia leiteira de Pelotas, RS, em diferentes meses do ano, verificaram diferenças (p<0,05) nos valores de crioscopia e acidez entre os meses avaliados. Durante os meses mais quentes, os autores observaram valores médios de acidez titulável que variaram de 16 a 17,5°D, e de crioscopia, de -0,536 a -0,544°H.…”
