Differences in Milk Production Efficiency and Physiology Between Lactating Holstein Cows and Yaks Born and Kept at About 4000 m of Altitude When Fed the Same Diet

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Yaks (Bos grunniens) have developed numerous mechanisms to cope with hypoxic environments. Still, as their milk yield is low, the use of production systems building on dairy breeds at high altitude might increase efficiency, but this has not yet been explored.

A Comparative Analysis of Creatine, Creatinine, Amino Acid Concentrations and Indispensable Amino Acid Scores of Grain‐Free and Grain‐Inclusive Commercial Extruded Adult Cat Foods

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Despite its role in energy and amino acid (AA) metabolism, no work has investigated creatine (Cr) content in commercial cat food. This study evaluated the Cr, creatinine (CrN), crude protein (CP) and AA concentrations of 30 commercial extruded cat diets.

Branching Out: Rabbit Models Provide Evidence for the Use of a Willow Cultivar (Salix miyabeana) as a Suitable Forage Material for Monogastric Herbivores in Zoos

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT We assessed the suitability of a willow cultivar for monogastric herbivores in zoos using a rabbit model. Thirty‐six male New Zealand White × Californian rabbits at 5 weeks of age were provided with bark and leaf material from a willow cultivar, Salix miyabeana (SX61), in one of four treatments for 6 weeks: UC (unrestricted control of pelleted

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.

Dietary Phosphorus Requirement for Tambaqui, Colossoma macropomum, in the Grow‐Out Phase

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Phosphorus is essential for fish growth as it is crucial in skeletal development and metabolic reactions. The dietary requirement for this mineral varies among fish species and growth stages. Therefore, the objective of this study was to determine the available phosphorus (AP) requirement for tambaqui during the grow‐out phase (± 400 to 1000 g)
