Abstract: Para se avaliar o efeito do plano nutricional e crescimento sobre a massa dos pré-estômagos, morfologia e quantificação de papilas ruminais, trinta e seis cordeiras da raça Santa Inês foram submetidas a dois planos nutricionais (ad libitum ou restrito) sendo abatidas em diferentes pesos vivo (20, 30 ou 40 kg de peso vivo), em um delineamento inteiramente casualizado balanceado em arranjo fatorial 2x3. Feito o abate, as vísceras foram pesadas livres de seu conteúdo em seguida mediu-se o volume de repleção do rú… Show more

“…In addition, the ruminal physiology should also be accounted for, where the lambs may have a disproportional development of the forestomach in relation to their body size until 90 days old, as described by Cavalcanti et al (2014). These authors also reported that a fast growth of the forestomach occurs after weaning, where its mass increase follows the body development in a proportional way (isogonic growth).…”

“…The height, thickness and shape of the papillae depend on the energetic composition of the feed. For papilla-height growth to occur, a large demand for energy is required, which must be intake through the feed offered (Cavalcanti, 2014). As the inclusion of the ionophore provided a higher amount of propionate, it can be inferred that there was greater substrate availability for papillae growth.…”
