Five or eight weeks of restricted suckling: influence on dairy calves’ feed intake, growth and suckling behaviour
Concern about welfare and behavioural needs of animals has increased the interest in keeping calf and cow together after parturition. In this experiment six calves suckled their dams twice a day for five weeks then once a day for three weeks (DAM8). Six calves (DAM5) suckled during five weeks in the same way as calves […]
Composition of captive giant panda milk
Abstract 10.1002/zoo.20056.abs Eleven milk samples were collected from three female giant pandas (Ailuropoda melanoleuca) during 23 days after delivery. Concentrations of crude protein (CP), lactose (Lac), and three vitamins (VA, VD, VE) in these samples were tested. Concentration of CP, Lac, VA, VD, and VE of these samples in wet basis averaged 6.77±0.78%, 3.23±0.54%, 0.073±0.043 […]
Characterization of Milk Cortisol Concentrations as a Measure of Short-Term Stress Responses in Lactating Dairy Cows
This study compares cortisol concentrations in plasma and milk over a time-span of 1-4h following injection of an adrenocorticotropic hormone (ACTH) or a physiological stressor. Its aim was to characterize the usefulness of milk cortisol concentrations as short-term measures of acute stress. Experiment 1: three groups of lactating cows (Groups B – D; n = […]
Behavior and body mass changes of a mother and calf Pacific walrus (Odobenus rosmarus divergens) during the suckling period
The behavior of a 13-year-old female Pacific walrus and her first calf is described during the first 7 months of the 19-month suckling period. The calf vocalized before 62% of suckling sessions. The mother immediately responded after 84% of vocalizations; after 44% she allowed a suckling session. The number of suckling sessions per 24-h period […]
The effect of conspecific removal on behavioral and physiological responses of dairy cattle
Adverse social and welfare implications of mixing dairy cows or separating calves from their mothers have been documented previously. Here we investigated the behavioral and physiological responses of individuals remaining after conspecifics were removed. We conducted a series of 4 experiments incorporating a range of types of different dairy cattle groupings [experiment 1 (E1), 126 […]
Application of the Welfare Quality protocol to dairy buffalo farms: Prevalence and reliability of selected measures
Within the general aim of developing a Welfare Quality system for monitoring dairy buffalo welfare, this study focused on prevalence and interobserver reliability of the animal-related variables to be included in the scheme. As most of the measures were developed for cattle, the study also aimed to verify their prevalence for buffaloes. Thirty animal-based measures […]
A functional approach to the body condition assessment of lactating donkeys as a tool for welfare evaluation
Background. The breeding of lactating donkeys is increasing in Western Europe; with it the evaluation of body condition is growing in importance since it is considered a key principle for their welfare. However, assessment of body condition is a complex task, since several factors are involved. The aim of the present study is to investigate […]
