The main objective of this work was to study the genetic and environmental components of calving ease in the Parda de Montaña beef breed. The calving ease score used to record field data was discussed conducting surveys to farmers. The number of calving ease records used in the study was 5,738. The ...

Mycoplasmal pneumonia of swine (MPS, also referred to as 'enzootic pneumonia', EP) caused by Mycoplasma hyopneumoniae (Mhp), is a chronic respiratory disease with the clinical sign of persistent dry cough. Epidemic of MPS has a negative impact on growth rate and feed conversion. The causative agent ...

Bordetella avium, the causing agent of bordetellosis, a highly contagious infection of the respiratory tract in young poultry, causes significant losses in poultry farming throughout the world. Wildlife birds can be a reservoir of various pathogens that infect farm animals. For this reason the...

The effects of heat stress on HSP90B1 messenger RNA (mRNA) expression in the hypothalamus of chicken were investigated and HSP90B1 variations were detected. Females of two Chinese chicken breeds (Huainan and Wenchang) were used for the experiments. At 64 days of age, the ambient temperature...

DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive sequences including three retrotransposons (...

Yak (Bos grunniens) is one of the world's most remarkable domestic animals and is regarded worldwide as an iconic symbol of the Tibetan Plateau and neighbouring high-altitude areas. Yak provide meat, milk, and wool as a major subsistence livelihood and financial income for local herders. Moreover,...

Yak is specially adapted to high-altitude environments and is a flagship species for the Hindu Kush Himalayan (HKH) region. It plays a key role not only in agrobiodiversity conservation and maintaining high-altitude rangeland ecosystems, but also in cultural traditions, livelihood strategies, and...

In pig breeding schemes, the traits of interest are measured in the grandparent or parent populations on purebred animals. However, the progress in these pure breeds should be expressed in the crossbred offspring. It is generally expected that the genetic relationships between traits measured on...

The study is based on fat thickness analysis with computed tomography (CT) of animals from 13 genetic types: purebred Piétrain-like breeds, crossbred Piétrain × Large-White types and crossbred fattening pigs. For each of the 280 analyzed half-carcasses, average fat thickness was calculated...

Use of the rabbit as a model and farm animals builds on the rich farming tradition in Slovakia. It is associated with the name of Jaroslav Zelnik, who put down the foundations for zootechnical and biological research of the rabbit at the early seventies of the 20th century. He built and managed the ...
