Examining Factors Of Variance In Energy Metabolism Of Dairy Cattle, Addison Lee Carroll
Examining Factors Of Variance In Energy Metabolism Of Dairy Cattle, Addison Lee Carroll
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Variation is thought to occur in the use of dietary energy for production in dairy cattle. First, variance can be observed when new methane mitigation strategies are fed resulting in increased H2 output potentially resulting in downstream effects on estimates heat production via the Brouwer (1965) equation. Therefore, in chapter 3 a review was created to systematically describe the mathematics and theory behind the Brouwer equation, and rederive a heat production equation to integrate H2 production. Results indicate heat production using the classical Brouwer equation (1965) relative to the rederived equation resulted in an overestimation of heat production …

The objective of the present study was to assess the effect of parturition on behavioral activity [steps, standing time, lying time, lying bouts (LB), and duration of LB] 4 d before calving using electronic data loggers. Animals (n = 132) from 3 herds were housed in similar freestall barns using a prepartum pen 21 d before the expected calving date and were moved into a contiguous individual maternity pen for parturition. Electronic data loggers were placed on a hind leg of prepartum heifers (heifers, n = 33) and cows (cows, n = 99) at 7 ± 3 d before the …
Cystic Ovaries In Dairy Cattle, Lacey Morgan Rosenberg
Cystic Ovaries In Dairy Cattle, Lacey Morgan Rosenberg
Dairy Science
The objective of this literature review was to determine the potential causes and factors affecting the incidence of ovarian cysts in dairy cattle as well as to examine functionality of various preventative methods and treatments of cysts. The end product was to be a document outlining all the information available on the three different types of cysts that can develop on the bovine ovary, follicular cysts, luteal cysts, and cystic corpora lutea. The literature that was reviewed, most in the forms of research papers, articles, and reviews, came primarily from scientific journals and published books. The literature reviewed was only …
