It is intended to evaluate the microbiota of the gastrointestinal tract in sheep supplemented with a zinc oxide nanoparticle (NP-Zn) as a functional food. In the digestive system of ruminants there is an intimate and complex relationship between the animal and the ruminal microbiota and the other compartments. Through the taxonomic diversity and function of the microbiota, he hoped to adv…
In this project the validity of zinc oxide nanoparticle (Zn-NP) supplementation in ruminant as a functional feed will be investigated, integrating different areas of knowledge (inter and multidisciplinary) such as chemistry, microbiology and animal sciences (nutrology , parasitology, genetics, reproduction and immunology) using advances of the "Omics" era. In an inedited and innovative w…
The hypothesis of this trial is to verify if there are differences associated with system and agro ecological zone in terms of the prevalence of AMR. Dietary and management interventions (such as tannins) might alter the microbiome of the host animal to alter its level of AMR. To test this, we would sample faeces from beef animals of different ages from a range of different systems and ag…
In Brazil, the meat production from sheep does not attend to domestic market, demand, it is required importation of this type of food. In this case the sheep production represent is a good opportunity in brazilian agribusiness. The herd nutrition, as well as, reproduction are key points for development of this sector. Measures aimed at reducing production costs are welcome. The availabili…
The continual advances seen in agricultural sciences are due to uninterupted experimentation worldwide. For these studies to produce intelligible answers, they need to be planned, conducted and interpreted according to the principles of Experimental Statistics. Frequently these analyses are carried out by professionals trained in statistics with little experience in biology, leading to a…

The aim of this work plan is to evaluate the hematological response of sheep supplemented with zinc oxide (ZnO) nanoparticles and infected with H. contortus. Sixty lambs will be divided into 6 treatments: Control without zinc supplementation (with and without H. contortus infection), micrometric ZnO (with and without H. contortus infection) and nanoparticle ZnO (with and without H. contor…
The aim of this work plan is to study the effects of supplementing sheep with zinc oxide nanoparticles (ZnO) and infected with H. contortus on egg counts and Zn content in feces. The experiment will consist of using 60 lambs divided into 6 treatments: Control without zinc supplementation (with and without H. contortus infection), micrometric ZnO (with and without H. contortus infection) a…
At this stage of the thematic project the validity of zinc oxide nanoparticle (Zn-NP) supplementation in ruminant as a functional feed will be investigated, integrating in areas of reproduction, microbiology, and molecular biology, using advances of the "Omics" era. It is intended to select Zn-NP with high bioavailability and greater persistence in animal organisms in an unprecedented and…
Zinc is an important micronutrient for the immune system, and biological processes such as growth, reproduction, wound healing, synthesis of DNA and proteins and antioxidant, obtained through food daily, because there is no specific tissue in the body animal for its storage. In ruminants, its absorption in the organism occurs through the mucosa of the abomasum and small intestine through …
The central element of this work is to conduct a survey to determine the prevalence of antimicrobial resistance (AMR) in bacteria as measured in the faeces of Brazilian beef cattle and the potential of tannins in antimicrobial properties and your antibiotic resistance modifying properties. Weaned cattle (approximately 12 months old) will be compared with finishing cattle (approximately 24…
The gastrointestinal nematode of sheep, Haemonchus contortus has been resistant to several active principles, among them Ivermectin, anthelmintic with antihelminthic resistance, but widely used for the treatment and control of gastrointestinal nematodes in sheep. Some mechanisms of resistance to ivermectin have been elucidated and the participation of the P-glycoprotein is listed as the m…

The sheep production represent is a good opportunity in brazilian agribusiness. The herd nutrition, as well as, reproduction are key points for development of this sector. Cottonseed is an importante food source can be used to ruminants diet. However, this seed has anti-nutritional factor called gossypol, that it has toxicity and can provide negatively affect on fertility in male. Thus, f…
