5. PRODUCTIVE PERFORMANCE OF PRE-WEANED CALVES REARED IN THE PANTANAL
Resumo A desmama precoce (DP) vem sendo adotada nas fazendas de cria do Pantanal como alternativa para o aumento dos índices de concepção das vacas. A principal receita dessas propriedades são os bezerros (as), sendo o seu valor dependente dos seus respectivos pesos. Assim é necessário que os bezerros submetidos à DP, apresentem pesos semelhantes ou a

7. Dietary level of cull pinto beans on animal performance, digestibility, and energy balance of pregnant-lactating hair ewes
ABSTRACT The objective of this study was to evaluate the effect of three levels of cull pinto beans (CPB) on animal performance, energy balance, and digestibility of hair ewes during pregnancy-lactation. One hundred and sixty-eight Pelibuey ewes were used (105 multiparous and 63 primiparous). Seven ewes of each type were randomly assigned to each of the 24 p

8. Perinatal effects of scorpion venoms: maternal and offspring development
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in th

9. Effects of excess maternal thyroxin on the bones of rat offspring from birth to the post-weaning period
ABSTRACT Objective To evaluate, in rat offspring, bone changes induced by excess maternal thyroxin during pregnancy and lactation, and to assess the reversibility of these changes after weaning. Material and methods Twenty Wistar rats were distributed in two groups, hyperthyroid and control, that were treated daily with L-thyroxin (50 mcg/animal) and pla

10. Models of protein and amino acid requirements for cattle
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became

11. Lipid peroxidation, detoxification capacity, and genome damage in mice after transplacental exposure to pharmaceutical drugs
Data on genome damage, lipid peroxidation, and levels of glutathione peroxidase (GPX) in newborns after transplacental exposure to xenobiotics are rare and insufficient for risk assessment. The aim of the current study was to analyze, in an animal model, transplacental genotoxicity, lipid peroxidation, and detoxification disturbances caused by the following
