1. Avaliação do potencial genotóxico do 51Cr2O3, marcador de digestibilidade, por meio da frequência de anormalidades nucleares em tilápias do Nilo (Oreochromis niloticus L.) / The evaluation of genotoxic potential of 51Cr2O3, a digestibility marker, by the frequency of nuclear abnormalities in Nile tilapia (Oreochromis niloticus L.)
Tilapia is the common name of a large number of species of cichlid fish. In aquaculture, this is one of the most profitable fish, since it presents lower feed conversion than other fish. The chromium oxide has been used as a marker for digestibility because it is inert and not alter the biological process of dietary intake. The use of radioactive form of chr

2. Avaliação de métodos para análise de nitrogênio amoniacal em fluido ruminal e de óxido crômico em amostras de fezes de bovinos / Evaluation of methods for analyses of ammonia nitrogen in rumen fluid and chromium in cattle feces
This dissertation was based on two different experiments. The first one was conducted to evaluate the accuracy of two different methods in measuring the ammonia nitrogen (N-NH3) concentration in rumen fluid: a catalyzed indophenol colorimetric reaction (CICR) and the Kjeldahl distillation (KD). Five buffered standard solutions containing volatile fatty acids

3. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o

4. Functional nutrients in the diet for male broilers maintained in high environmental temperature / Nutrientes funcionais em rações de frangos de corte mantidos em ambiente de alta temperatura
A thousand two hundred male broilers of Cobb strain were used in three experiments to evaluate in animals assigned to high temperatures the effect of functional nutrients (organic chromium, vitamin C and vitamin E) on the performance and noble cuts. In each experiment were evaluated five treatments that were distributed in a randomized experimental design wi

5. Desempenho e perfil metabólico de bovinos da raça nelore suplementados com cromo orgânico
O objetivo desse experimento foi avaliar os efeitos da suplementação com cromo orgânico sobre o desempenho e os teores de glicose, lipídios totais e de colesterol total em bezerros da raça Nelore criados a pasto. Utilizaram-se 20 bezerros, machos, Nelores, com peso inicial médio de 179 kg e 6 meses de idade. O delineamento utilizado foi inteiramente ca
