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 effect of climate on dairy and beef cattle is variable and complex because it affects the environment in which the animals are raised and reproduced. Its influence on animal welfare and production have been recognized and studied since 1950's. Climate affects livestock directly and indirectly...

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...

Nutritional recommendations of the past 35-40 years have promoted the reduction of fat intake, calories and particularly saturated fatty acids (SFA), emphasizing lower consumption of red meat and high fat dairy products, because of its association with cardiovascular diseases (CVD), being in turn...

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...

A mechanistic model (COWPOLL) was used to estimate enteric methane (CH4) emissions from beef production systems in Chile. The results expressed as a proportion of gross energy intake (GEI) were compared with enteric fermentation data reported in the last Chilean greenhouse gases inventory, which ...
