Seasonal changes in diet, digestive morphology and digestive efficiency in the Rufous-collared Sparrow (Zonotrichia capensis) in central Chile
(University of California Press, 1996)
Modulation of digestive enzyme activities in the avian digestive tract in relation to diet composition and quality
(Springer Heidelberg, 2017-02)
In nature, birds are faced with variable food sources that may differ in composition (protein vs. carbohydrates) and quality (highly digestible material vs. indigestible fiber). Studies in passerine birds and some commercial ...
Ileal amino acid digestibility in micronized full fat soybean meal and textured soy flour fed to piglets with or without multicarbohydrase and phytase supplementation
(2017-07-01)
Most amino acid (AA) digestibility values for feed ingredients are obtained using ileal-cannulated pigs. The ileal-cannulated pig model is not used with pigs younger than six weeks of age due to difficulties related to ...
Responses of anaerobic microorganisms to different culture conditions and corresponding effects on biogas production and solid digestate quality
(2016)
Microbial communities of anaerobic digestion have been intensively investigated in the past decades. Majority of these studies focused on correlating microbial diversity with biogas production. The relationship between ...

Influência da retirada de digesta abomasal, para estudos de digestão parcial, sobre a digestibilidade aparente de nutrientes com bovinos
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 1997-09-01)
The objective of this trial, using 21 abomasal fistulated bovines, eight months of age and 187 kg of liveweight, was to evaluate the digestibility coefficients of diets containing different protein sources (dry yeast, urea, ...
Nutrient digestibility, but not mineral absorption, is age-dependent in cats
(Wiley-Blackwell Publishing, Inc, 2010-12-01)
Availability of nutrients is influenced by extremes of age, and a better characterization of this influence is necessary for appropriate development of foods and nutritional management throughout life stages of cats. This ...
Effect of Phytase Supplementation in Diets on Nutrient Digestibility and Performance in Broiler Chicks
(Poultry Science Assoc Inc, 2008-06-01)
A performance trial was conducted with broiler chicks to Study the effect of phytase (PHY) supplementation in diets formulated With reduced AME, Ca, and P. The nutrient digestibility was determined during the 14- to 21-d ...
