Passage Rate of Feed in Very Young Chicks
White Leghorn chicks were reared on diets in which soybean oil at 4% or corn oil at 5 or 10% was substituted isocalorically for carbohydrate calories. The transit time ( TRT ) of diets was determined in these chicks with ferric oxide as a marker. The average TRT for three experiments was 167 min. Overall, there was no significant effect (P greater than

Quantifying the Availability of Vertebrate Hosts to Ticks: A Camera-Trapping Approach
The availability of vertebrate hosts is a major determinant of the occurrence of ticks and tick-borne zoonoses in natural and anthropogenic ecosystems and thus drives disease risk for wildlife, livestock, and humans.

Rumen degradation and passage kinetics of silage made from different corn hybrids
The objective of the present study was to evaluate the parameters related to the digestion of the fiber from silages of four corn hybrids (BX1280, SHS4070, 2B433, and DKB390) developed for silage production.

This study ascertained the influence of liquid passage rates on solid digesta passage rates and the possibilities of simultaneous prediction of solid and liquid passage rates in ruminants. Artificial neural networks were used to develop models of solid and solid-plus-liquid passage rates.
