The high content of crude protein (CP) of pastures in southern Chile creates a nutritional imbalance that results in large amount of nitrogen (N) being excreted into the environment. Two regression equations and a dynamic model, available from the literature, were utilized to simulate the N use e...

A summer study and a winter study were conducted using an incomplete factorial structure in a complete randomized design. Within season, the factors studied were 1) type of diet, which included 2 levels of ME, classified as either concentrate (3.04 Mcal of ME/kg) or roughage (2.63 Mcal of ME/kg) ...

Records from 7 studies conducted during 1999 to 2005 were utilized to assess the effects of environmental factors on daily water intake (DWI) of finishing cattle. Data from unshaded feedlot pens (up to 24 pens utilized per study; 6 to 9 animals.pen(-1)) containing predominantly Angus crossbred ca...

Meteorological data from December to January of years 1999 to 2007 from weather stations located in four localities in Chile (Curico, Chillan, Temuco and Osorno) were used to calculate the adjusted temperature-humidity index (THIadj-max). Climate variables used to calculate the index were: wind s...

Simple Summary Improving efficiency in beef cattle production requires the adoption of technologies that are low cost but high in return. High potency growth-promoting implants (HGPs) are widely used under feedlot conditions but there are few reports of their use under grazing conditions. We cond...

The in vitro crude protein (CP) digestibility (D-ivcp), true protein digestibility (D-tp) and degradation rate (kd(cp)) were measured in different protein extracts of Saccharomyces cerevisiae (Sc) yeast. These extracts were generated through a biotechnological method (solid state fermentation). W...

In a first experiment, the effect of in vitro incubation with Aspergillus niger (An) on the chemical composition of different fibrous substrates was studied. In a second experiment, the effect of incubation time (0, 72 and 144 h) on in vitro digestion with An of dry matter (IVDMD), neutral deterg...
