Comparison Of Spayed Heifer Performance To Intact Heifers Fed Melengestrol Acetate On Feedlot Performance And Carcass Characteristics, Tate S. Johnson, Rebecca L. Mcdermott, Halden J. Clark, Jim C. Macdonald, Jessica L. Sperber

Nebraska Beef Cattle Reports

Summary with Implications

Pregnancy and estrous cycle management are critical considerations when feeding intact heifers in the feedyard. Alternatively, producers can opt to spay heifers, which eliminates hormonal fluctuations associated with the estrous cycle. A proportion of U.S. feedlots have spayed heifers on feed, although there is limited data comparing the performance of spayed heifers to intact heifers. A commercial feedlot experiment was conducted to compare performance between spayed and intact heifers fed melengestrol acetate. Intact heifers had greater ADG and tended to have greater DMI compared to spayed heifers, although no difference in feed conversion was observed. Carcass weight …

Turkish Journal of Veterinary & Animal Sciences

Septic peritonitis is a serious, life-threatening condition with a high mortality rate. Accurate diagnosis is crucial for the survival of the affected animal. The present study analyzed the use of a blood-to-fluid gradient of glucose and lactate as a biomarker in the diagnosis of septic peritonitis. Thirteen dogs with septic peritonitis and nine dogs with aseptic peritonitis were included in this study. Blood-to-fluid glucose gradient was significantly high, and blood-to-fluid lactate gradient was significantly low in septic peritonitis compared with the aseptic peritonitis. A blood-to-fluid glucose gradient of ≥12 mg/dL showed 100% sensitivity and 55.6% specificity, whereas a blood-to-fluid lactate …

Determination Of The Cecal Microbiota Profile Of Anadolu-T Broiler Breeder Chickens Using 16s Metagenomic Sequencing, Kürşat Teti̇k, İsmai̇l Özkan, Serpi̇l Kahya Demi̇rbi̇lek

Turkish Journal of Veterinary & Animal Sciences

The gut microbiota has significant effects on the performance, health status, and immune systems of chickens. The complex microbial community structure begins to form after chicks hatch with the intake of feed, water, and air into the digestive system. Disrupting the balance of this system can lead to the proliferation of pathogenic microorganisms. Until recently, studies on microbiota relied on traditional microbiological techniques that cultured only a small fraction of the microbial diversity. However, significant advancements in DNA sequencing and bioinformatics have enabled the identification of diverse bacterial populations in environmental samples. In this study, a total of 2000 broiler …

Differences In Lactation Curve Parameters And Milk Yield Responses Between Artificially Induced And Naturally Calved Cows Milked In An Automatic Milking System, Marcos Busanello

Turkish Journal of Veterinary & Animal Sciences

Despite advances in artificial induction of lactation (AIL) protocols, they do not perfectly mimic the hormonal patterns of natural pregnancy. Recent studies show improved milk yield (MY) responses; however, comparisons of lactation curve parameters between AIL and naturally calved (NC) cows often do not extend beyond 305 days in milk (DIM). Thus, this study aimed to compare MY responses and lactation curve parameters between AIL and NC cows milked in an automated milking system (AMS). Data from 38 Holstein cows (19 AIL and 19 NC) were analyzed, focusing on the 305 DIM period. Wood’s lactation curve model was used to …

Recovery And Characterization Of Moraxella Species From Bovine Specimens, Laura G. Leger

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The family Moraxellaceae is made up of a diverse group of 24 named species that fall into three phylogenetic groups. While most Moraxella spp. act as commensal respiratory and/or ocular flora of mammals, some are associated with disease. One of these diseases, infectious bovine keratoconjunctivitis (IBK), has significant welfare and economic impacts to both cattle and cattle producers. Moraxella bovis is the only experimentally determined cause of IBK, however, an association of Moraxella bovoculi with disease has been proposed. Currently, available vaccines do not have high levels of efficacy in the field. Culture based methods are the gold standard for …
