Problems with Congestive Heart Failure and Lameness That Have Increased in Grain-Fed Steers and Heifers.

Grain-fed steers and heifers have increasing problems with both lameness and congestive heart failure. Congestive heart failure used to be limited to cattle raised at high altitudes. It is now occurring at much lower elevations.

Mother-Offspring Bonding after Calving in Water Buffalo and Other Ruminants: Sensory Pathways and Neuroendocrine Aspects.

The cow-calf bonding is a process that must be developed within the first six hours after calving. Both the buffalo dam and the newborn calf receive a series of sensory cues during calving, including olfactory, tactile, auditory, and visual stimuli. These inputs are processed in the brain to develop an exclusive bond where the dam provides selective care to the filial newborn.

Human animal relationships in cattle breeds addressed from a Five Domains welfare framework.

The present review has two objectives, the first is to investigate the differences in temperament between and breeds and determining the effects on production due to positive treatment and to compare this with negative HAR, by using the Five Domain Model as framework. The second objective is to discuss potential strategies to achieve better HAR when working with cattle. are more reactive and temperamental than cattle.

Tactile, Auditory, and Visual Stimulation as Sensory Enrichment for Dairy Cattle.

Several types of enrichment can be used to improve animal welfare. This review summarizes the literature on the use of mechanical brushes, tactile udder stimulation, music, and visual stimuli as enrichment methods for dairy cows. Mechanical brushes and tactile stimulation of the udder have been shown to have a positive effect on milk yield and overall behavioral repertoire, enhancing natural behavior.

Physical and behavioural health of dogs belonging to homeless people.

Homeless persons with dogs are often the subject of stigma, with the public criticising them for not having a proper lifestyle to care for a pet. There is solid documentation of how dogs enhance a homeless person's life, but there are few publications that address the welfare of the dog. This descriptive study assesses the physical and behavioural health of dogs belonging to homeless persons through a One Welfare lens by observing animal/human well-being, environment, and "a life worth living".

Slaughtering of Water Buffalo () with and without Stunning: A Focus on the Neurobiology of Pain, Hyperalgesia, and Sensitization.

The slaughter process in livestock is considered a stressor where the transport and handling of animals, as well as the selected stunning and bleeding methods, can cause acute pain, distress, and suffering. In water buffaloes, although stunning is known to be performed before bleeding to induce unconsciousness, no emphasis is made on the nociceptive events during this process. Particularly, current mechanical stunning methods applied to cattle are unsuitable for water buffaloes due to anatomical differences in the skull from other large ruminants.

A Practical Approach to Providing Environmental Enrichment to Pigs and Broiler Chickens Housed in Intensive Systems.

In Europe, regulations contain guidance to maintain high standards of animal welfare. In many parts of the world, large buyers for supermarkets or restaurants are the main enforcers of basic animal welfare standards. They can have considerable influence on improving standards on large commercial farms.

Effects of udder edema on parlor behavior in first- and second-lactation Holstein dairy cows.

Udder edema (UE) is a metabolic disorder that most commonly occurs around the transition period. However, gaps exist in our knowledge about its effects on parlor behavior. The aim of this study was to examine the prevalence and effects of UE on behavior in the milking parlor during udder preparation and active milking from 2 to 9 days in milk in first- (FL) and second-lactation (SL) Holstein dairy cattle.

Answers to Patient, Student, and Clinician Questions About How Animals Are Slaughtered and Used for Food.

"Do cattle and other animals know they are walking up a chute that will lead to their death?" Many people ask this question, which the author first had to answer when starting work in the cattle industry. From observations at slaughter plants, feedlots, and ranches, the author learned that cattle behavior was the same when entering a chute for vaccination and when entering a chute for slaughter. If cattle knew they would die, their behavior should have been wilder and more agitated at the slaughter plant, but that was clearly not the case.

Practical Application of the Five Domains Animal Welfare Framework for Supply Food Animal Chain Managers.

The author has worked as a consultant with global commercial supply managers for over 20 years. The focus of this commentary will be practical application of The Five Domains Model in commercial systems. Commercial buyers of meat need simple easy-to-use guidelines.

Grazing Cattle, Sheep, and Goats Are Important Parts of a Sustainable Agricultural Future.

Many people believe that animal agriculture should be phased out and replaced with vegetarian substitutes. The livestock industry has also been attacked because it uses vast amounts of land. People forget that grazing cattle or sheep can be raised on land that is either too arid or too rough for raising crops.

Cattle and Pigs Are Easy to Move and Handle Will Have Less Preslaughter Stress.

Previous research has clearly shown that short-term stresses during the last few minutes before stunning can result in Pale Soft Exudative (PSE) pork in pigs or increased toughness in beef. Electric prods and other aversive handling methods during the last five minutes are associated with poorer meat quality. Handlers are more likely to use aversive methods if livestock constantly stop and are difficult to move into the stun box.

Evaluating the Reaction to a Complex Rotated Object in the American Quarter Horse ().

It is dangerous for both riders and horses when a horse suddenly startles. Sometimes horses do this in familiar environments because familiar objects may look different when rotated. The purpose of this study was to determine whether horses that had been habituated to a complex object (children's playset) would react to the object as novel when rotated 90 degrees.

An observational field study on the effects of changes in shadow contrasts and noise on cattle movement in a small abattoir.

This observational field study examined the effect of changes in shadow contrasts on the floor and noise on balking behavior during handling. Seventy-four Bos taurus beef cattle were observed during handling at a small abattoir. Shadow contrast type (none, soft, sharp) was recorded during three stages of handling (unloading, lairage to single-file alley and into stun box).

Impacts of group stunning on the behavioral and physiological parameters of pigs and sheep in a small abattoir.

This study investigated reactions of pigs (N = 148) and sheep (N = 77) to group stunning where animals were present for the slaughter of others. Mock stunning with an isolated animal was used as the control. In both species, there was little evidence to suggest a difference in blood glucose and cortisol with stun order (P ≥ 0.

Methods to Prevent Future Severe Animal Welfare Problems Caused by COVID-19 in the Pork Industry.

In the U.S., the most severe animal welfare problems caused by COViD-19 were in the pork industry.

Graduate Student Literature Review: Udder edema in dairy cattle-A possible emerging animal welfare issue.

Physiological udder edema is a noninfectious metabolic disorder in dairy cattle, which may be present in a high percentage of dairy cows. This review summarizes the factors associated with udder edema. They include genetics, nutrition, oxidative stress, and physiological changes in freshening heifers.

The Temple Grandin Genome: Comprehensive Analysis in a Scientist with High-Functioning Autism.

Autism spectrum disorder (ASD) is a heterogeneous condition with a complex genetic etiology. The objective of this study is to identify the complex genetic factors that underlie the ASD phenotype and other clinical features of Professor Temple Grandin, an animal scientist and woman with high-functioning ASD. Identifying the underlying genetic cause for ASD can impact medical management, personalize services and treatment, and uncover other medical risks that are associated with the genetic diagnosis.

From unloading to trimming: studying bruising in individual slaughter cattle.

Livestock bruising is both an animal welfare concern and a detriment to the economic value of carcasses. Understanding the causes of bruising is challenging due to the numerous factors that have been shown to be related to bruise prevalence. While most cattle bruising studies collect and analyze data on truckload lots of cattle, this study followed a large number ( = 585) of individual animals from unloading through postmortem processing at five different slaughter plants.

Sensor analysis and initial assessment of detectable first hoof contacts and last break-overs as unique signal fluctuations for equine gait analysis.

The objective of the control study was to assess 2 prominent fluctuations in a single optical signal as being either a true first hoof contact or a last break-over based on descriptive measures. The study builds on initial findings from a preliminary investigation of the embedded-optical-base system's (EOBS) capabilities in signal capturing and feasibility as potential alternative to existing gait technologies, such as piezoelectric (e.g.

The Use of Traditional Fear Tests to Evaluate Different Emotional Circuits in Cattle.

Animal temperament is complex and has implications for productivity and economic profitability. Quantifying an animal's response to differing stimuli may facilitate breeding selections and identify animals that are better suited to specific management strategies. Multiple tests have been developed to evaluate cattle temperament (e.
