Boreal Foraging Strategies [PDF]

, 1983
In 1974–1976, in the book Zoonomia or the Laws of Organic Life, Erasmus Darwin (1794) speculated that modification of species was brought about through the satisfaction of three wants. He identified them with admirable directness as “lust, hunger, and danger.” In the more prosaic but parallel terminology of contemporary evolutionary ecology these have ...

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

Animal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Mid-term fertilisers and lime effect on grassland in the hilly-mountain region in Balkan

Plant, Soil and Environment
Although the effects of fertiliser addition and liming on semi-natural grassland productivity and biomass quality are well documented, less is known about how fertilisers change plant functional groups and mean ecological values.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.
