1. Performance and development of gastric compartments of calves fed with cheese whey and transition milk
RESUMO: Objetivou-se avaliar se o soro de queijo associado ou não ao leite de transição poderia servir como uma alternativa adequada ao leite integral para a criação de bezerros. Para isso, 24 bezerros machos, mestiços Holandês-Zebu, foram distribuídos em delineamento inteiramente casualizado com três tratamentos (oito bezerros por tratamento) e al

2. Aspectos morfológicos do rúmen, omaso e fígado de tourinhos alimentados com diferentes níveis de glicerina bruta
ABSTRACT The morphology of the ruminal and omasal mucosa and hepatic parenchyma of 44 young bulls submitted to four types of concentrates were evaluated by varying the inclusion level of crude Glycerin - CG (0, 6, 12 and 18%). The variables evaluated were number of ruminal papillae per cm² of wall; area of the papillae and total absorption surface per cm²

3. Desempenho e desenvolvimento ruminal de bezerros em sistema de desaleitamento precoce recebendo aditivos alternativos aos antibióticos / Performance and rumen development of calves under early weaning program receiving alternative additives to replace antibiotics
Two studies were conducted to evaluate alternative additives to replace antibiotics on dairy calves production under early-weaning program. On the first trial, the addition of mannanoligosaccharides (MOS) in the diet of dairy calves on performance and plasma parameters indicative of rumen development, as well as the route of administration, milk replacer or

4. Inclusion of organic acids salts or sodium monensin in the starter feed and its effects on rumen development and performance of dairy calves / Inclusão de sais de ácidos orgânicos ou monensina sódica no concentrado inicial e seus efeitos no desenvolvimento ruminal e desempenho de bezerros leiteiros
Dois experimentos foram conduzidos com o objetivo de avaliar o efeito da inclusão de butirato de sódio, monensina sódica ou propionato de cálcio no concentrado inicial, sobre o desempenho, parâmetros sanguíneos e desenvolvimento ruminal de bezerros leiteiros. No primeiro experimento, 24 bezerras recém-nascidas da raça Holandesa foram alojadas em abri

5. AvaliaÃÃo morfofisiolÃgica da absorÃÃo e metabolizaÃÃo de Ãcidos graxos volÃteis pelo proventrÃculo de bovinos. / Morphophysiologic evaluation of the absorption and metabolism of volatile fatty acids by bovine forestomach.
About 60% of volatile fatty acids (VFA) produced in reticulorumen are absorbed in this compartment. The other 40% pass with the fluid phase to the omasum and are absorbed before entering the duodenum. Two experiments were carried out to determine the absorption surfaces and the VFA absorption and metabolism capacity of the bovine forestomach compartments. In

6. Evaluation of rations with different physical forms for Holstein heifers / AvaliaÃÃo de raÃÃes com diferentes formas fÃsicas para bezerros leiteiros
Performance and development of the rumen are related with the age in which the animals initiate the ingestion of forage and concentrate; these factors can be controlled by the diet, getting a calf ruminant with 7 to 8 weeks old. As faster this development occurs, higher the economical profit in modern systems of calves feeding. Authors are unanimous in affir

7. Lactate, propionate and butyrate induced morphological alterations on calf ruminal mucosa and epidermis. / AlteraÃÃes morfolÃgicas induzidas por Butirato, Propionato e Lactato sobre a mucosa ruminal e epiderme de bezerros
Volatile fatty acids (VFA) may cause morphological alterations on bovine keratinized stratified epithelial tissues. The objective was to evaluate the effect of butyrate, propionate and lactate on ruminal wall, the epidermis of nasolabial surface, the perioplum and the epicera of calves. Also, to validate the procedure and interpretation of tegument biopsies
