Abstract:
... Bite mass is the dry matter ingested per prehension bite. It has previously been reported that sward characteristics such as herbage height, density and allowance can affect bite mass in grazing cows. Animal characteristics such as liveweight and incisor arcade breadth may also affect bite mass. Understanding factors that influence bite mass can lead to an improvement in the estimate of dry matter ...

Abstract:
... Two experiments were conducted to investigate the influence of age and dietary cellulose levels on the ileal endogenous energy losses (IEEL) in broiler chickens. In experiment 1, a glucose-based purified diet was used to determine the IEEL. Titanium dioxide (5.0 g/kg) was added to the diet as an indigestible marker. Six groups of broiler chickens aged 1 to 7, 8 to 14, 15 to 21, 22 to 28, 29 to 35 ...

Abstract:
... Among the endocannabinoids, N-arachidonylethanolamide (AEA; anandamide) plays a key role in regulating energy homeostasis and energy intake. Recent studies suggest the existence of a peripheral mechanism by which AEA increases feed intake in the short term and modulates whole-body energy metabolism in dairy cows. Here, we aimed to test the hypothesis that AEA has a long-lasting central effect in i ...

Abstract:
... Direct measurements of methane (CH₄) from individual animals are difficult and expensive. Predictions based on proxies for CH₄ are a viable alternative. Most prediction models are based on multiple linear regressions (MLR) and predictor variables that are not routinely available in commercial farms, such as dry matter intake (DMI) and diet composition. The use of machine learning (ML) algorithms t ...
