Development of ovarian germline stem cells in Nile tilapia (Oreochromis niloticus) reared under different temperature regimes
(2017-02-14)Germ cells originate from progenitor cells, denominated as primordial germ cells (PGC). PGC are of extragonadal origin and migrate toward the gonad primordia where they proliferate and, in gonochoristic species, differentiate ... -
Zirkulierende Nukleinsäuren als molekulare Marker zur Trächtigkeitsbestimmung beim Rind
(2012-07-12)Circulating nucleic acids (CNAs) are specified as DNAs and RNAs outside cells that are circulating in the blood free or wrapped in membrane vesicles of healthy and diseased individuals. In this study CNA profiles from serum ... -
Quantitative and molecular genetic studies on temperature-dependent sex determination of Nile tilapia (<i>Oreochromis niloticus</i>)
(2012-06-13)Tilapia is one of the most important species group for aquaculture production. Particularly Nile tilapia (Oreochromis niloticus) amounts to over 80 % of the world tilapia production. All-male populations are favourable due ... -
Temperature Dependent Sex Determination In Zebrafish (Danio rerio)
(2012-02-23)Summary Despite zebrafish (Danio rerio) is an important model for understanding vertebrate development during the last decades, sex determination and differentiation are not ... -
Detection of new allotypic variants of bovine antibody λ-light chain and IgG-heavy chain constant regions
(2012-02-15)In the cattle breeds German Black Pied (GBP), German Simmental (GS), Holstein Friesian (HF) and Aubrac (A) the transcribed λ-light chain (IGλ) and the IgG heavy immunoglobulin chains (IgG) ... -
Temperature dependent sex differentiation in rainbow trout (Oncorhynchus mykiss)
(2010-11-01)The aim of the project was the evaluation of an alternative to the usage of hormonal treatment in order to produce rainbow trout neo-males for an all female production by mating these ... -
Erfassung und Risikoanalyse von niedersächsischen Aquakulturbetrieben vor dem Hintergrund der Fischseuchengesetzgebung
(2010-07-20)From a global view no sector within the food producing chain has grown so fast as aquaculture production business during the past four decades. However this development can neither be ... -
Untersuchungen zum leistungsabhängigen Bedarf an Lysin, Methionin/Cystin und Threonin von Nil-Tilapien auf Grundlage der Aminosäure-Wirksamkeit in ausgewählten Proteinträgermischungen
(2005-01-05)The objective of this investigation was to determine the amino acid efficiency of lysine, methionine/cystine and threonine in different mixtures of protein sources as a basis for the derivation of the amino acid requirement ... -
The Impact of Adaptive Performance on Holstein Breeding in Northern Thailand
(2003-04-07)Actual production and breeding status of a Northern Thai dairy herd (Holstein) was investigated in order to identify data basis for developing sustainable breeding concept for the local ... -
Study to determine maximum growth capacity and amino acid requirements of Tilapia genotypes
(2002-07-11)The present study was carried out in three experiments with three different genotype of Tilapia. The first genotype was pure male Oreochromis niloticus, the second was red Tilapia Oreochromis ... -
Untersuchungen über die Eignung beiochemischer und molekulargenetischer Marker für eine Identifizierung von verschiedenen Störarten und deren Hybriden
(2001-11-07)The goal of this thesis was to explore the potential of different biochemical and molecular markers to discriminate different sturgeon species. Blood samples were collected from the ...
