A comparison of fecal output determined by total fecal collection or titanium dioxide in horses. [PDF]

J Anim Sci
Abstract Total fecal collection studies to determine digestibility of nutrients are costly and laborious. The use of externally dosed indigestible markers, such as titanium dioxide (TiO2), to estimate digestibility using spot samples could be advantageous, but studies validating their use in horses are inadequate. Two experiments were

Efeitos de indicadores e dias de coleta na digestibilidade dos nutrientes e nas estimativas do valor energético de alimentos para vacas alimentadas com diferentes fontes de proteína Comparison of internal markers and extent of total fecal collection to estimate nutrient digestibility and energy value of feeds on dairy cows fed different protein sources

Revista Brasileira de Zootecnia, 2006
Foram utilizadas 12 vacas da raça Holandesa, entre puras e mestiças, distribuídas em três quadrados latinos 4 x 4, organizados de acordo com os dias em lactação, com o objetivo de avaliar o efeito de dois períodos de coleta de fezes (dois ou seis dias ...

Experimental chronic noise is related to elevated fecal corticosteroid metabolites in lekking male greater Sage-Grouse (Centrocercus urophasianus). [PDF]

, 2012
There is increasing evidence that individuals in many species avoid areas exposed to chronic anthropogenic noise, but the impact of noise on those who remain in these habitats is unclear.

Effects of Dietary Wheat Bran on Ileal and Hindgut Digestibility of Nutrient in Pigs and Influences of Ileal Digesta Collection on Proceeding Fecal Nutrient Digestibility

Animals, 2023
The objectives were to determine the effects of graded inclusion rates of wheat bran (WB) on apparent ileal (AID), apparent total tract (ATTD), and hindgut digestibility of nutrients and tested the influence of ileal digesta collection on proceeding ...

A Feces-Urine Separator for Making Total Fecal Collections from the Female Bovine [PDF]

Journal of Range Management, 1979
A simple, effective urine deflector is described for use in making total fecal collections in female cattle. A standard fecal bag is used with only slight modifications. Total fecal collection bags have been used in many grazing and confinement trials to determine feed digestibility and intake in cattle (Harris et al. 1967).
