Role of termites for the distribution patterns of carbon and phosphorus fractions and the genesis of tropical soils, Brazil
(2012-07-27)
Tropical soil fertility is limited by low phosphorus (P) availability, limited accumulation of organic matter and by advanced stages of pedogenesis. Termites are well-known soil-engineers, which accumulate clay, organic ......
Die Bedeutung von Termiten für die Verteilungsmuster von Kohlenstoff- und Phosphor-Fraktionen sowie die Genese Tropischer Böden, Brasilien
Die Bodenfruchtbarkeit in den Tropen ist durch eine geringe ......
A fertilidade dos solos tropicais é limitada pela baixa disponibilidade de fósforo, a falta de acumulação de matéria orgânica, e por estados avançados de pedogênese. Os térmitas ou cupins são bem-conhecidos 'engenheiros ......

Identification of candidate genes for boar taint using RNA deep sequencing
(2013-07-11)
The aim of the present study was to identify candidate genes for boar taint using RNA deep sequencing. For this purpose, two experiments were performed. In the first experiment, transcriptome profiling was analyzed in the ...
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
(2013-08-20)
With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through ...
Molecular genetic analysis of bovine oocytes with different developmental potentials
(2009-06-04)
Poor oocyte developmental potential contributes to reduced fertility in livestock species and hampers the application of biotechnology techniques in cattle industry that could be used for spreading certain genotypes with ...
Factorial Approach to Determining Energy and Protein Requirements of Gilthead seabream (Sparus aurata) for Optimal Efficiency of Production
(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 ...
Candidate gene analysis for loci affecting sperm quality and fertility of boar
(2005)
Fertility is one of the most important economical traits in swine production. Implementation of artificial insemination (AI) in swine production allowed improving selection on the boars for production traits, but at the ...
Molecular genetic analysis of positional candidate genes for mammary gland characteristics in pigs
(2005)
Inverted teat reduce the number of functional mammary complexes in affected sows leading for reduction of piglet productivity and litter growth during the lactation period. This detect occures in commercial pig breeds with ...
Die Wirkung der Mikrogravitation auf das Abwehrsystemvon Schwertträgerfischen (Xiphophorus helleri, Heckel)in einem geschlossenen, aquatischen Ökosystem: immunologische und hämatologische Untersuchungen
(2006)
Background: The effect of space flight conditions on the immune system of humans and rodents was investigated since the beginning of space flight. Until now there were no investigations of the influence of microgravity ...
Expression analysis of homeobox gene family in bovine pre- and post-implantative developmental stages
(2006)
Homeobox (hox) genes encode transcription factors which regulate the expression of several target genes encoding essential proteins for cell differentiation and proliferation. Thus, hox-genes have long been recognized as ...
Genetic factors affecting the omega-3 and omega-6 fatty acid variation in egg yolk
(2006)
This study aimed to elucidate the genetic divergence of quail lines selected for high and low ω-6:ω-3 PUFAs ratio in the egg yolk by estimation of the genetic parameters, to clone and characterize of the direct candidate ...
