Respiration rate (RR) is a common measure of cattle health and welfare. Traditionally, measuring RR involves counting flank movements as the animal inhales exhales with each breath. This method often considered difficult, labour-intensive impractical. We validated use infrared thermography (IRT) an alternative non-invasively in young calves. was simultaneously recorded two ways: (1) by observing from video recordings; (2) thermal fluctuations around nostrils during inhalations exhalations...
Eye temperature measured using infrared thermography (IRT) can be used as a non-invasive measure of autonomic nervous system (ANS) activity in cattle. The objective this study was to evaluate if changes eye (measured IRT) non-invasively ANS sheep. Twenty, 2 4-year-old, Romney ewes were randomly assigned receive either epinephrine (EPI) or physiological saline (SAL) for 5 min administered via jugular catheter (n = 10 ewes/treatment). (°C) recorded continuously IRT approximately 25 before and...
Background: Metabolic Bone Disease of Prematurity (MBDP) is common in extremely preterm infants (≤28 weeks gestation). Parenteral nutrition (PN) with higher calcium (Ca) and phosphorus (P) concentration started soon after birth may improve bone health infants. We compared the effect two standard PN formulations on incidence MBDP explored predictive ability biochemical markers for diagnosing MBDP. Methods: This retrospective study included eligible ≤ 28 gestation. Infants group 1 (January...
As the reliance upon automated systems in livestock industry increases, technologies need to be developed which can incorporated into these monitor animal health and welfare. Infrared thermography (IRT) is one such technology that has been used for monitoring welfare and, through automation, potential integrated on-farm. This study reports on an system collecting thermal infrared images of calves development validation algorithm capable automatically detecting analysing eye cheek regions...
Systemic postnatal corticosteroid use in extremely preterm infants poses a risk of adverse neurodevelopmental outcomes. This study explores their beyond seven days age with early assessments during the fidgety period (9-20 weeks postterm age).
Background: The administration of live microbiota (probiotic) via enteral route to preterm infants facilitates intestinal colonization with beneficial bacteria, resulting in competitive inhibition the growth pathogenic bacteria preventing gut microbiome dysbiosis. This dysbiosis is linked pathogenesis necrotizing enterocolitis (NEC), an acquired multi-factorial disease characterized by microbial invasion mucosa, particularly affecting infants. Probiotic prophylaxis reduces NEC; however,...
Despite the clear importance of drinking water, calves are not always provided water on farm for first few weeks life. The main objective this study was to investigate effects provision (access or no access) and milk allowance (high low) behavior growth rate calves. Fifty mixed-breed were each assigned 1 4 treatments: (1) high (10 L/d) (n = 13), (2) 12), (3) low (5 (4) 13). Visits trough, intake, (visits speed), proportion observations eating hay calf starter, lying recorded from when were,...
Otoreflectance (OR) is a newly developed multifrequency middle ear function test instrument utilizing acoustic signals, which are presented and recorded in the canal. It provides an objective measurement of transfer for frequency range 0.25 to 8.0 kHz. In present study, reflectance measurements were performed 25 subjects (50 ears) using experimental OR system. The energy (ER) was plotted against each 1/6-octave frequencies from Three types ER-plot configurations found subject with normal...
Controversy exists regarding the use of a radiopaque agent to identify peripherally inserted central catheter (PICC) tip positions in newborn infants and serial radiography monitor PICC migration.
Objective This study aims to determine the effect of infant–mother separation following a short-stay (≤72 hours) admission Level 5 neonatal unit versus no on infant-feeding outcomes at hospital discharge. Design Retrospective cohort study. Setting An Australian within tertiary referral hospital. Participants Mothers and their infants born between 1 January 2018 31 December 2020 had or admission. All participants met criteria postnatal ward were discharged home ≤72 hours (n=12 540). Postnatal...
In New Zealand, dairy goats are predominantly housed on sawdust; however, previous studies suggest that may prefer alternative surfaces. Therefore, the aim of this study was to evaluate effect four different flooring types goat behavior and cleanliness. At 6 mo age, 32 female Saanan cross does (45.4 ± 6.10 kg) were restricted one for 10 d, then other three surfaces (10 d per surface) using a Latin square design consisting eight replicates (n = 4 replicate). The included sawdust (SW), metal...
Monitoring and targeting mean arterial pressure
Abstract Measured using infrared thermography (IRT), changes in eye temperature, can be used to non-invasively measure pain response husbandry procedures such as disbudding calves. Previous studies have manually recorded IRT controlled studies, however, it would of interest determine if could temperature an automated on-farm system. Therefore, the objective this study was detect dairy calves on-farm. At 3 wk age, 51 Friesian were allocated 1 5 treatment groups: 1) sham handling (SHAM, n =...
Abstract Feeding behavior can be measured using automated calf milk feeding systems, that record total number of visits consisting rewarded (milk consumed) or unrewarded (no visits. Unrewarded either when the is entitled to milk, but does not drink (“Entitled”), so cannot (“Non-entitled”). used as an indicator sickness in calves; fewer feeder has been shown a sensitive measure onset illness. However, greater understanding would aid early detection disease calves. This study aimed evaluate...
