One of the major challenges in lameness management is prompt detection, especially before visible gait disturbance. This scoping review describes the potential biomarkers for lameness in dairy cows reported in the literature, their relevance in lameness diagnosis, identifying cows at risk of developing claw lesions and monitoring recovery after tre...

Background: The objectives of this study were to, (1) investigate the impact of the Dutch five-step hoof trimming (HT) technique on time to lameness and hoof lesion prevalence in grazing (GR) and non-grazing (NGR) dairy cows, and (2) determine the association between potential benefits of HT and animal-based welfare measures during lactation. A tot...

The objectives of this study were to describe the prevalence of hoof lesions, their relationship with lameness, and associated risk factors in dairy cows in Peninsular Malaysia. Hoof lesion data were recorded after hoof examination on 1,051 cows from 29 dairy farms in 4 states (Selangor, Johor, Negeri Sembilan and Perak) from December 2018 to June...

Tuberculosis (TB) is a chronic inflammatory and zoonotic disease caused by Mycobacterium tuberculosis complex (MTBC) members, which affects various domestic animals, wildlife, and humans. Some wild animals serve as reservoir hosts in the transmission and epidemiology of the disease. Therefore, the monitoring and surveillance of both wild and domest...

Lameness is a major welfare issue in dairy cows. This study was aimed at investigating the cow- and herd –level factors associated with lameness in dairy farms from four states in Peninsular Malaysia. The study population was 1001 lactating cows from 28 dairy farms located in Selangor (n = 9), Perak (n = 8), Negeri Sembilan (n = 6) and Johor (n = 5...

Lameness resulting from claw lesions remains a pressing welfare issue in dairy cows. Claw trimming (CT) is a common practice for prevention and management of clinically lame cows. This review summarizes the results of studies that have investigated various claw trimming (CT) methods, their application in lameness management, and associations with t...

Background Intramammary Infections are costly endemic diseases in dairy cows and it highly affect both the quality and quantity of milk production in addition to the animal wellbeing. It a major cause of considerable economic losses to the dairy farmers. This study was aimed to determine the prevalence of mastitis pathogens and antimicrobial resist...

(1) Background: The objective of this study was to determine the prevalence of T. gondii in meats of cattle, goat and sheep from wet markets in Klang Valley, and abattoirs in Selangor, Malaysia; (2) Methods: A total of 192 meat samples were purchased from 51 wet markets in six districts in Klang Valley (Gombak, Klang, Kuala Lumpur, Hulu Langat, Pet...

The development and utilization of nano-antibiotics is currently gaining attention as a possible solution to antibiotic resistance. The aim of this study was therefore to determine the pharmacokinetics of free oxytetracycline (OTC) and oxytetracycline loaded cockle shell calcium carbonate-based nanoparticle (OTC-CNP) after a single dose of intraper...

Background Evaluation of the toxic effects of nanoparticle-drug in vitro is an important step in the design of new pharmaceutical formulations. Rapid results, reduced cost and easy handling makes cell culture models first line in initial toxicological assessment of nanodrug preparations. Objective To evaluate the in vitro cytotoxicity of oxytetrac...

Farmers play an integral role in minimizing disease threats and managing ongoing diseases on their farms. Various environmental factors influence the decision-making processes of farmers. Deciphering the mental models of farmers allows us to understand the motivations and reasons behind disease prevention and control choices. This study aimed to ex...

Intramammary infections are costly endemic disease in dairy cows and it highly affects both the quality and quantity of milk production in addition to the animal well-being. It a major cause of considerable economic losses to the dairy farmers. This study was aimed to determine the prevalence of mastitis pathogens and antimicrobial resistance patte...

We report the whole-genome sequence of Escherichia coli sequence type 127 (ST127) strain 1538RHQ, recovered from a mastitic cow in a dairy herd in Selangor, Malaysia. The objective of this study was to identify the antigenic and virulence properties that can be used as suitable targets for vaccine development against bovine mastitis.

Alternative drug delivery for the treatment of resistant bacterial infections is necessary to bypass existing antibiotic resistance mechanism and ensure direct delivery of the drug to the targeted site using locally sourced materials to minimize cost in the long term. In this study, cockle shell-derived calcium carbonate aragonite nanoparticles (CS...

Staphylococcus aureus (S. aureus) is a major cause of mastitis in small ruminants, and studies on the potential application of acute phase proteins (APPs) in disease biomarkers and understanding the disease mechanism in mastitis affecting small ruminants are limited. Thus, the objective of this study was to determine clinical, histopathological cha...

Lameness continues to be a welfare and economic issue for dairy cows. However, the consequences of lameness seem to be better understood by veterinarians and related personnel in comparison to dairy farmers. Prompt detection and treatment of lame cows is essential in reducing its negative impact on milk processing systems. To that end, understandin...

Streptococcus agalactiae, commonly known as group B streptococcus (GBS), is among the most implicated pathogens in bovine mastitis worldwide. Proper control measures can curb both economic and public health effects it may cause. Here, we report the sequenced genome of S. agalactiae sequence type 167 (ST167) strain 3966RFQB obtained from a bovine ma...

THE IMPACT OF LAMENESS ON DAIRY CATTLE WELFARE: GROWING NEED FOR OBJECTIVE METHODS OF DETECTING LAME COWS AND ASSESSMENT OF ASSOCIATED PAIN

Newcastle disease (ND) remains an important enzootic disease in chickens in several parts of the world. With the increasing reports of virulence and genetic diversity of the causative agent; Newcastle disease virus (NDV), there is a need to identify the circulating NDV in specific regions. In Oman, to this moment, such information is still lacking....

Newcastle disease (ND) is an endemic disease in Oman’s poultry industry and impacts negatively on food security. However, little is known regarding the potential risks of the disease in backyard poultry. The objectives of this study were to determine the seroprevalence of Newcastle disease virus (NDV) in backyard chickens and the herd-level risk fa...

The increasing public health problem of antimicrobial resistance (AMR) has been linked to the extensive antimicrobial use (AMU) in food animals. We conducted a survey among ruminant farmers in Selangor, Malaysia to assess their level of awareness on AMR, attitudes towards AMU, and determinants that influence their practices. The survey was develope...

This study was designed to characterise the lameness cases in cattle reported to the University Veterinary Hospital (UVH) of Universiti Putra Malaysia (UPM), Serdang, Selangor. Medical records from 2013 to 2017 were reviewed and 136 cases of cattle diagnosed as lameness were retrieved. Information concerning signalment, location of lesions, and cau...

The objectives of this cross-sectional study were to estimate the prevalence of lameness, claw lesions, and associated risk factors in dairy farms in Selangor, Malaysia. The sample population was 251 lactating cows from 8 farms assessed for lameness and claw lesions by locomotion scoring and claw assessment respectively while specific animal-based...

Dairy cow welfare is an important consideration for optimal production in the dairy industry. Lameness affects the welfare of dairy herds by limiting productivity. Whilst the application of LS systems helps in identifying lame cows, the technique meets with certain constraints, ranging from the detection of mild gait changes to on-farm practical ap...

In recent times, several infectious and zoonotic diseases have emerged as major threats to the health of people and animals globally, resulting in suffering and death of human and animals. The One Health Manual, an initiative of Malaysia One Health University Network (MyOHUN), is the first local Manual to deal with zooneses outbreak investigation b...

This manual was prepared by a multidisciplinary team; for some this was a first experience working in an One Health team. The exercise of preparing this manual provided us with the opportunity to understand each other’s invaluable role in zoonotic disease prevention and control. It is our fervent hope that the users of this manual will benefit from...
