In-Vivo Assessment Of A Direct-Fed Microbial On Lactation Performances, Blood Biomarkers, Ruminal Fermentation And Microbial Abundance In Transition To Mid-Lactation Holstein Cows, Marcela Bulnes Lopez
In-Vivo Assessment Of A Direct-Fed Microbial On Lactation Performances, Blood Biomarkers, Ruminal Fermentation And Microbial Abundance In Transition To Mid-Lactation Holstein Cows, Marcela Bulnes Lopez
Electronic Theses and Dissertations
The transition period is a crucial stage in the lactation cycle and can lead to significant metabolic changes in cows. The use of nutritional interventions, such as direct-fed microbials, may assist cows during the transition from pregnancy to early lactation, reducing the occurrence of metabolic disorders and improving overall health. The primary goal of this study was to assess the effects of a commercial rumen-derived directfed microbial (DFM) product (Galaxis™ Frontier (GF) Native Microbials Inc., CA, USA) on various factors such as performance, blood biomarkers, rumen fermentation, and bacterial population in dairy cows during the transition period up to 100 …
Physiological Responses To Feeding A Yeast Culture Supplement To Transition Dairy Cows, Nathaly Ana Carpinelli
Physiological Responses To Feeding A Yeast Culture Supplement To Transition Dairy Cows, Nathaly Ana Carpinelli
Electronic Theses and Dissertations
The transition period is the dynamic stage in the lactation cycle, where the most metabolic changes can occur. The use of nutritional strategies, such as yeast culture, can help cows during the transition from pregnancy to early lactation, improving health and decreasing the incidence of metabolic disorders. The first objective of this research was to evaluate the effects of a commercial yeast culture product (YC; Cellerate Culture Classic HD, Phibro Animal Health, Teaneck, NJ) on performance, blood biomarkers, and rumen fermentation and bacterial population in dairy cows during the transition period through 50 days in milk (DIM). Overall, the results …
Impact Of Saccharomyces Cerevisiae Fermentation Product On Feed Intake Parameters, Lactation Performance, And Metabolism Of Transition Dairy Cattle, K. Olagaray, S. E. Sivinski, B. A. Saylor, L. K. Mamedova, J. A. Sauls, I. Yoon, B. J. Bradford

Kansas Agricultural Experiment Station Research Reports
ASaccharomyces cerevisiaefermentation product (NutriTek; Diamond V, Cedar Rapids, IA) was fed from 29 ± 5 days before calving and through 42 days in milk (DIM) to evaluate the effects on feed intake parameters, milk production, and metabolism. Treatments were control (n= 30) or 18 g/d NutriTek (NT,n= 34) provided as total mixed rations. Cows were individually fed 3×/day prepartum and 2×/day postpartum. Cows were milked 2×/day with samples taken 2×/week for composition analysis. Body weight (BW) was measured at enrollment (day -29 ± 5), day 0, and day 42 relative to calving, and body …
Differences In Behavioral And Physiological Variables Measured With Precision Dairy Monitoring Technologies Associated With Postpartum Diseases, I Ching Tsai
Theses and Dissertations--Animal and Food Sciences
The transition period is defined as the three weeks before and three weeks after the cow calves. Transition cow diseases are considered production diseases. Precision dairy monitoring (PDM) technologies measure physiological, behavioral, and production indicators on individual animals to improve management strategies and farm performance. The objective of the first study was to assess how hypocalcemia, hyperketonemia, and metritis affected variables measured by PDM technologies. The objective of the second study was to use variables from multiple commercially available PDM to examine alert performance generated from different analyses.

Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × …
