Summary: This study demonstrates that dynamic measures of BCS during the late dry period, such as increment BCS, are better at evaluating blood BHB patterns in early lactation. Cows that lose more BCS during the late dry period are more likely to develop hyperketonemia postpartum and have lower milk production. Higher parity is also associated with higher blood BHB concentrations postpartum, with the peak being at 7 days post-calving.

Summary: The objectives of this experiment were to determine the effects of supplementing 25-hydroxyvitamin D3 compared with vitamin D3 at 1 or 3 mg/d in late gestation on production outcomes of dairy cows. The results showed that feeding 25-hydroxyvitamin D3 increased colostrum and milk yield compared to vitamin D3. The effect of 25-hydroxyvitamin D3 on milk yield may be related to serum calcium concentrations.

Summary: The study aimed to assess the impact of selective dry cow therapy (SDCT) on commercial dairy farms in reducing antimicrobial consumption without compromising future performances compared to blanket dry cow therapy (BDCT). The trial involved 12 commercial herds in Belgium, with 466 cows assigned to either BDCT (n = 244) or SDCT (n = 222) groups. The results showed that SDCT significantly reduced total antimicrobial usage for udder health compared to BDCT, without affecting SCC values, milk yield, clinical mastitis, and culling hazard in the first 100 days in milk.

Summary: Consumers are increasingly choosing organic farming products because they believe that organic farms do not use pesticides or antibiotics and that animals are provided with the best living conditions. This review discusses the comparison between organic and conventional dairy cattle housing systems in terms of welfare assessment, breed selection, and product quality. It has been shown that cows kept in organic systems usually have better welfare compared to conventional breeding, but conventional farms can also provide better animal welfare through the use of pasture grazing. The taste of milk is affected by pasture feeding, but this depends on consumer preference.

Summary: Recently, the use of antimicrobials on dairy farms has been significantly limited due to legislative and consumer concerns. This study investigates the effectiveness of selective dry cow therapy (SDCT) compared to blanket dry cow therapy (BDCT) on bovine udders in healthy animals. The results show that selective dry cow therapy can be conducted without increasing the risk of new intramammary infections or raising the somatic cell count at calving, as long as the cows are healthy and have a somatic cell count of >200,000 cells/mL in the previous lactation.

Summary: Negative energy balance affects milk yield, composition, and animal health in dairy cows. Studying the effects of feed restriction (FR) experiments is essential to understand the physiological changes induced by negative energy balance. These protocols can impact animal metabolism, hormonal regulations, mammary gland activity, and ultimately milk production and composition.

Summary: During the peri-parturient period, the development of the fetus and the production of colostrum and milk increase the energy and mineral requirements in ruminants, leading to a higher risk of metabolic diseases. This study investigated the effects of sugar beet pulp and anionic salts on preventing peri-parturient hypocalcemia in Chios dairy sheep. The results showed that the administration of sugar beet pulp and anionic salts during the dry period had a beneficial effect in preventing hypocalcemia. It is concluded that feeding sugar beet pulp and systemic acidifying before parturition is safe and might even be beneficial in preventing hypocalcemia.

Summary: The purpose of this study was to evaluate the ovarian and energy status of lame dairy cows in the puerperium stage and analyze their response to estrous synchronization treatment. The study found that lame cows were more likely to experience non-cycling, had higher blood fat concentrations, and a higher incidence of elevated blood fat concentrations compared to non-lame cows. However, there was no significant interaction between energy status and lameness in terms of non-cycling cows. In conclusion, lame cows in the puerperium stage are at a greater risk of not cycling, regardless of their energy status.
