| The main components in milk from cows that are affected by mastitis can be in different amounts according to the racial characteristics. Thus, the association between the somatic cell counts (SCC) and these components may also differ in milk from Jersey cows. This study evaluated the effect of the SCC in milk from Jersey cows on milk production and its physicochemical composition. For 71 months, data from 3244 milking and 300 cows were evaluated considering the effect of the SCC on milk production (kg cow day-1), percentage of fat, protein, lactose, total solids, and nonfat solids. The probable factors associated with fluctuation in milk production based on somatic cell score, lactation number and rainfall were also evaluated by regression models. Milk... |

| ABSTRACT: This study aimed to evaluate the effects of replacing oat hay with coffee husk in the diet of lambs on the intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), non-fiber carbohydrate (NFC), neutral detergent fiber (NDF), and acid detergent fiber (ADF). The experimental design was 4×4 Latin square with four levels of replacement of oat hay with coffee husk (0, 7.5, 15, and 22.5%) with four individually housed Texel sheep. Intake and apparent digestibility coefficients were measured at four periods of 12 days. All orts and feces were collected, weighed, homogenized, and sampled. The use of coffee husk at up to 22.5% of the total DM in the diet of lambs improved the intake of nutrients.... |
