Reliability of 2D Ultrasound Measurements of Testis Size in Dolphins Taken Under Voluntary Behavior

The Role of Preventative Medicine Programs in Animal Welfare and Wellbeing in Zoological Institutions

“…Generally referred to as medical husbandry or husbandry training, the integration of operant conditioning to all aspects of husbandry and veterinary care with an emphasis on positive reinforcement is transforming the field and enhancing animal welfare and wellbeing [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. By training the caretakers and the animals to perform medical behaviours, many high-risk procedures can be carried out without the need for chemical or manual restraint [53,54].…”

B-Mode ultrasonographic evaluation of the testis in relation to serum testosterone concentration in male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) during the breeding season

“…In past decades, the clinical application of ultrasonography in veterinary medicine and animal reproduction has expanded dramatically, and the value of this technique in breeding both domestic and nondomestic species has been well documented [14][15][16][17][18][19]. As animals are trained to cooperate, ultrasonographic examinations have aided in determining the reproductive status of captive cetaceans [20][21][22][23]. Nevertheless, no previous research has used this approach to evaluate the reproductive physiology of YFPs.…”
