Supplementation of cattle with rumen undegraded protein (RUP) sources may be an important strategy to supply nutritional deficiencies from forage and increases the amino acid utilization efficiency, consequently increasing performance. However, this supplementation may result in different amino acids duodenal flow when animals are maintained during dry or rainy season; this is due to the …
Any animal operation that lacks proper nutrition, feeding management and waste-disposal program has the potential to pollute the environment. In this regard, animals are fed inadequate nutrient amounts, that are not used efficiently for production (e.g., meat and milk), large quantities of the nutrients may be excreted and potentially contributing to environmental degradation. In this sce…
The project aims to evaluate the effect of different levels of metabolizable protein supply in the growing on performance, protein metabolism and emission of greenhouse gases (methane emissions (CH4), nitrous oxide (N2O) and volatilization of ammonia (NH3)), as well as effect of preconditioning beef steers rearing on finish of beef cattle in Brazil, in two typical scenarios (feedlot or su…

The acute-phase inflammatory response is an immune process that is activated by different internal and external factors such as stress. During inflammatory responses, protein metabolism is altered to support an increase in nutrient demand of the immune system. Such alteration can negatively affect animal health, wellbeing and performance; however, nutritional strategies arise as alternati…
The present study aims to evaluate the influence of different sources of non-degradable protein in the rumen on the population of methanogenic Archaea and methane production in Nelores cattle finished in feedlot. It will be used 8 Nellore steers, average live weight of 380 kg, castrated and cannulated in the rumen. The animals will be allocated in individual stalls and distributed in a cr…
The use of rumen undegradable protein sources (RUP) in the dry season can be an important strategy to overcome the nutritional deficiencies of forage in this period and increase the efficiency of N utilization in pasture animals. This study aims to evaluate the influence of rumen undegradable protein supplementation or not on ruminal intake, nutrient digestibility, metabolism and ruminal …
The aim of this study is to compare the use of three types of samples (NET fraction, solid fraction and net fraction + solid) and three schedules (0, 4 and 8h after feeding) of ruminal content collection, to identify and quantify the total population of Archaeans Methogenic in cattle using molecular methods. Will be used four Nellore cattle cannulated in the rumen (mean body weight of 445…

Precision agriculture has emerged as a promising means of improving food production efficiency for field crops. However, measurements associated with most current precision agriculture technologies are single use, discrete, and require follow-up action by humans. In contrast, precision livestock farming requires continuous monitoring of animals and their environment in an autonomous manne…
Performance of cattle in northern Australia, just like in Brazil, depends on the capacity of the animals to efficiently extract nutrients during periods of restricted availability. Therefore, the ability of the animal to recycle nitrogen back to the rumen, instead of eliminating in the urine, is crucial. The internship will be developed from August to November 2019 at The University of Qu…
Trace minerals have long been identified as essential components in the diets of domestic livestock species. Dietary Cu and Zinc, when fed at physiological concentrations, can be alter lipid metabolism. Therefore the main objectives of this experiment are to determine the effects of: 1) copper and zinc source on performance, mineral status, lipogenic gene expression, and carcass character…
