Evaluation of health, production parameters, time to first detected estrus, and behavior in dairy cows treated with pegbovigrastim

Xavier da Silva Oliveira, Mauricio 13 December 2019 (has links)
Pegbovigrastim injection (IMR) represents a new approach in overcoming mastitis. The objective of this study was to evaluate production parameters, overall health, time to first detected heat, and behavior of cows treated with IMR or a saline control. Study cows (n = 270) were blocked by parity group (multiparous or primiparous) and randomly assigned to control (CON, n = 144) or treatment (IMR, n = 126). Milk yield, fat, protein, lactose, solids nonfat percent, somatic cell count, and body condition, hygiene, and lameness were evaluated weekly. Animals were evaluated for metritis twice weekly via evaluation of rectal temperature, per rectum palpation, and uterine discharge until 30 days in milk. Farm staff recorded occurrence of other diseases. Neck tag and a leg tag, each with activity monitoring sensors, measured behavior and time to first detected estrus. The occurrence of clinical mastitis did not differ between treatments. Treated cows were 2.46 times more likely to develop metritis compared to control cows. Cows given IMR had increased odds of developing metritis, without altering mastitis occurrence, production parameters, behavior, and time to first heat in lactating dairy cows.

Einfluss verschiedener bestandsspezifischer E. coli-Vakzinen auf die Eutergesundheit von Milchrindern

Heine, Manuela 10 April 2014 (has links) (PDF)
Die Mastitis beim Milchrind hat eine große ökonomische Bedeutung, daher liegt derzeit ein Forschungsschwerpunkt auf der Aktivierung und Stabilisierung der körpereigenen Abwehr zur Bekämpfung von Euterentzündungen. Besonders im peripartalen Zeitraum liegt eine Prädisposition für Infektionen vor, da eine physiologische Abwehrschwäche besteht. Daher erscheint die Förderung der Bildung von Antikörpern durch Impfungen sinnvoll. Getestet wurde der Einfluss von bestandsspezifischen E. coli-Vakzinen auf das Immunsystem, das Erregervorkommen in der Milch und die Eutergesundheit. Differenziert wurden Impfstoffe, die einerseits aus den Originalkulturen der antigenen Erreger (sogenannte large colony variants, LCV) oder aber aus den kleineren, intrazellulär persistierenden Erregern (small colony variants, SCV) hergestellt wurden. Letztlich zeigte sich bei Anwendung der Vakzinen an Milchrindern kein Unterschied zwischen LCV und SCV, bei beiden Impfstoffen war eine vakzinationsbedingte deutliche Steigerung der Antikörpertiter, welche einen Einfluss auf Erregervorkommen und Eutergesundheit hatte, erkennbar.
