Brucellosis is a bacterial disease of many domestic and wild animals with great economic and public health importance. Although it has a major constraint in dairy production, comprehensive information regarding the epidemiology of brucellosis in dairy herds is limited. Besides, evaluating the dairy farmers' knowledge, attitude, and practice (KAP) regarding brucellosis is crucial for generating information that can enhance control programs and public health interventions.

Although peritonitis is highly prevalent in cattle, there have been only limited studies on the pathology of this condition. We describe the gross and histological aspects of primary and secondary peritonitis in cattle based on necropsy reports of 46 cases. Twenty-six were female (26/46; 56.

We evaluated the effects of breed and mineral source on heifer performance during periods of nutrient restriction and grazing. On day -7, ½ Angus × ½ Nelore (ANE) and Nelore (NE) heifers (12 heifers per breed; body weight, BW = 264 ± 35 kg; age = 15 ± 1 mo) were assigned to individual drylot pens to receive ad libitum Tifton 85 (Cynodon sp.) hay and white salt for 7 days.

Department of Agronomy, Food, Natural Resources, Animals and Environment, University of Padova, 35020 Legnaro (PD), Italy.
In recent decades, a general increase in multiple birth (MB) rate has been reported in both dairy and dual-purpose cattle breeds. As there is evidence that MB has negative effects on economically important traits in dairy cows, the aims of this study were to (i) investigate environmental and genetic factors affecting MB rate and (ii) assess the impact of MB on productive and nonproductive traits of the Austrian dual-purpose breeds Pinzgauer and Tyrol Grey. The dataset included 99,141 calvings of 33,791 Pinzgauer and 68,454 calvings of 19,244 Tyrol Grey cows recorded from 2000 to 2022.

Council on Dairy Cattle Breeding, Bowie, MD 20716.
Over the past decades, various methods have been proposed to estimate daily milk yields from partial yields. Many of these methods divide milking interval time into varied classes, assuming that the yield correction factors are constant within classes but vary between classes. The DeLorenzo and Wiggans (D-W) method has been widely used in the United States, typically following a 2-step process.
