Milk fat yield affects the price received for milk by dairy farmers, and given the rising feed costs, maximizing diet digestibility is critical for the economical viability of dairy farms. Although feeding animal-vegetable fat or coconut oil to dairy cows can increase energy intake, they sometimes cause milk fat depression (MFD). Feeding monensin has been found to increase feed efficiency and m...

Nearly all herbivorous arthropods make foraging-decisions on individual leaves, yet systematic investigations of the adaptive significance and ecological factors structuring these decisions are rare with most attention given to chewing herbivores. This study investigated why an intracellular feeding herbivore, Western flower thrips (WFT) Frankliniella occidentalis Pergande, generally avoids fee...

Corn dried distiller’s grain with solubles (cDDGS) is a feeding ingredient for monogastric animals but limited inclusion rate due to its imbalanced amino acids, high fiber content, and anti-nutritional compounds. Moreover, production of cDDGS costly energy intensive. This study investigated fungal fermentation corn stillage mixing other dry agro-industrial residues which could by-pass the energ...

BACKGROUND Combined iron overload and alcohol may promote synergistic chronic liver injury and toxicity. The role of specific dietary fats in influencing the development of co-toxic alcoholic liver disease needs further evaluation and is investigated in this study. METHODS Wild-type (WT) and the iron-loaded Hfe-null (Hfe(-/-) ) mice were fed chow (CC), a AIN-93G standard control (SC), or a co...

 During the early stages of white fish, survival rate is a very effective parameter on future fry’s sustainability, especially when they are going to be released into the natural habitat for restocking. The aim of this study is to define relationships between morphological and functional traits and the survival rate of the European white fish fry (Coregonus lavaretus) when they were fed with di...

Trypanosoma rangeli infects several triatomine and mammal species in South America. Its transmission is known to occur when a healthy insect feeds on an infected mammal or when an infected insect bites a healthy mammal. In the present study we evaluated the classic way of T. rangeli transmission started by the bite of a single infected triatomine, as well as alternative ways of circulation of t...

The primary control of autophagically mediated proteolysis in perfused rat liver is carried out via two alternate mechanisms in response to specific regulatory amino acids. One (L) elicits direct inhibition at low and high plasma levels, but requires a co-regulatory amino acid to express inhibition at normal concentrations. The second (H) is ineffective at normal levels and below, but active at...
