Effects of different feeding regimes applied during rearing of dairy calves: circulating adiponectin and insulin sensitivity in early life and around the first lactation
Kesser, Julia (2016-12-20)Metabolic programming is defined as an early stimulus with long term effect. In dairy cows, feeding in the preweaning period has long term effects on later milk production. However, the influence on metabolic and endocrine ... -
Effects of different milk replacer feeding levels during a 14-week preweaning phase in heifer calves: Characterisation of the oxidative status and the mammary gland development by ultrasound imaging
Seibt, Katharina Diana (2022-03-15)The development of dairy heifer calves and especially their mammary glands is crucial for the productivity of the future dairy cows. Conventional rearing of dairy heifer calves is still based on restrictive milk or milk ... -
Effects of folic acid and pantothenic acid supplementation to two rations on rumen fermentation, duodenal nutrient flow and serum and milk variables of dairy cows
Ragaller, Veronika (2010-04-08)The aim of the present experiments was to investigate the influences of a daily supplementation of 1 g folic acid (FA), respectively pantothenic acid (PA) on ruminal fermentation, as well as on serum and milk variables. ... -

Der Einfluss von Nonylphenolen auf die Entwicklung des Nervensystems und die synaptische Plastizität
Jockschat, Carina (2019-11-13)Bei Nonylphenolen handelt es sich um eine Gruppe chemischer Verbindungen mit aromatischem Ring, Hydroxylgruppe und einer Nonyl-Seitenkette, die entweder verzweigt oder linear vorliegen kann. Das technische Nonylphenol ... -
Einsatz von Immunstimulatoren als Alternative zu Leistungsförderern in der Schweinehaltung
Schmitz, Simone; Hiss, Stephanie; Sauerwein, Helga (2003)Vor dem Hintergrund der zu erwartenden fortschreitenden legislativen Einschränkungen beim Einsatz von sogenannten Fütterungsantibiotika, werden sogenannte Immunstimulatoren als Futterzusätze zunehmend diskutiert. ... -
Endocrine activity of adipose tissues as influenced by energy intake in the periparturient cow
Weber, Martina (2016-02-09)With the onset of lactation, dairy cows have to mobilize body reserves, mainly in form of fat, to cover the energy output via milk. Homeorhetic adaptations, achieved via the orchestrated actions of hormones, are necessary ... -
Epigenetic and exosome-mediated cell-cell communication in follicular cells and preimplantation embryos
Zidane, Mohammed Saeed (2017-12-21)Follicular cells and preimplantation embryos communication with their in vivo or in vitro environments via mechanisms including cell adhesion and extracellular vesicles is crucially essential for normal oocyte and embryo ... -
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
Yang, Qin (2016-05-24)Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ... -
Establishment of an experimental model for dairy cows of divergent peripartal mobilization of body reserves: Profiling circulating steroid hormones and the mRNA abundance of steroid metabolizing enzymes in liver and in adipose tissue
Schuh, Katharina (2021-12-16)The lactation cycle of dairy cows is characterized by physiological, metabolic, and endocrine changes that also affect adipose tissue (AT) function and portion. These changes include lipogenesis during periods of nutrient ... -
Expression of genes related to energy balance in adipose tissue of dairy cattle: effects of SCFA on mRNA abundance as quantified by qPCR and relevance of appropriate selection of reference genes
Hosseini, Afshin (2010-11-05)The aim of this thesis was to study the effect of propionate (C3) and β-hydroxybutyrate (BHB) on the mRNA abundance of reference genes (RGs) and of the genes of interest (GOI) related to energy balance, by short term ... -
Factorial Approach to Determining Energy and Protein Requirements of Gilthead seabream (Sparus aurata) for Optimal Efficiency of Production
Lupatsch, Ingrid (2004)Requirements for dietary energy and protein in growing fish can be quantified using the factorial approach which assumes that the requirement is the sum of growth and maintenance. Thus dietary intake can be calculated using ... -
Function and regulation of AMP-activated protein kinase in in vitro development and lipid metabolism of preimplantation bovine embryos
Prastowo, Sigit (2015-07-14)One of the major problems associated with the in vitro production of bovine embryos is lipid accumulation due to the presence of serum in culture media. AMP-activated protein kinase (AMPK) is well documented as a master ... -
Futtermittelkundliche und ernährungsphysiologische Bewertung von Rapskuchen für Milchkühe
Koch, Christian (2011-08-02)In den letzten Jahren war ein ständig zunehmender Rapsanbau in der Bundesrepublik Deutschland zu verzeichnen. Gründe hierfür waren eine erhöhte Biodieselnachfrage sowie die Nutzung von Rapsöl in der Humanernährung. Als ... -
