Pork meat quality
The quality of pork is the result of a combination of genetic and environmental factors. There are four major criteria used in measuring pork quality: color, marbling, water-holding capacity, and ultimate pH.
Pork quality comprises a variety of attributes related to the characteristics of the product itself and the conditions under which pigs/pork are produced. Each of these attributes is influenced by various individual factors, ranging from pig genetics to pork preparation for consumption, and their interactions. Pork quality is built along the whole food chain, with synergies and antagonisms between quality attributes. Moreover, the priority attributes depend on chain stakeholders, from the farmer to consumer. Different production and processing methods from farm to fork are identified to improve pork quality according to the priorities and trade-offs between attributes and stakeholders.
Introduction: There are many proper alternatives that can be used to meet the nutritional requirements of swine while reducing feed cost. Wheat has a higher content of crude protein and lysine than those of corn. In addition, many researchers reported that wheat could substitute for corn in growing-finishing pig without negative effects on growth performance and improve better carcass than pigs fed corn (Han et al., 1976; Bell and Keith, 1994; Han et al., 2005)....

Introduction: Temporary Veterinary Inspectors (TVIs) detain slaughter pigs ante mortem (AM) for closer inspection if they have concerns regarding their health and welfare. In this study, we evaluated 164 detained pigs, all passed as fit for slaughter, to investigate if there is a relationship between the AM status of detained pigs and their condemnation level post mortem (PM). Materials and Methods: Data collection took place over 5 days in a single Irish...

Introduction: International price of swine feed ingredients such as corn and soybean meal has increased continually due to soaring oil price and increasing bio-fuel production. Palm kernel meal (PKM) can be one of alternative ingredients in swine feeds because of its extensive availability, adequate nutrients, comparable price and large amount of production. Therefore, this experiment was conducted to evaluate different levels of dietary PKM with ß-mannanase on growth...

Introduction: The fluctuation in price of major feed ingredients is affecting cost of production in swine industry. Therefore, alternative ingredients to reduce feed cost become more important than before. Palm kernel meal (PKM) is a by-product after extracting palm oil in tropical area. There were various studies to evaluate PKM supplementation instead of corn and SBM in growing-finishing pig’s diet. However, there was no information for optimal level of dietary...

Canada is one of the largest pork and beef exporters in the world. The volume and value of Canadian meat exports have increased to ~$9 billion/year, and the export markets have expanded significantly from the traditional buyers. However, the meat export landscape has evolved during the last years, becoming more competitive, with major players trying to access the same import markets. Quality assurance and meat differentiation based on quality attributes contribute to meeting domestic and...

Introduction: Previous studies have led to observations regarding the negative impact of non-starch polysaccharides in corn-soybean meal diets on nutrient digestibility. Therefore, steps are undertaken to positively influence nutrition in livestock by utilizing enzymes. This experiment was conducted to evaluate the effects of ethyl-enzyme liquid energy (ELE) on growth performance, nutrient digestibility, meat quality traits and carcass grades of grower-finisher...

Introduction: Using antibiotics as growth promoters in animal feeds has been forbidden since 2011 in South Korea. Probiotic have received considerable attention as suitable alternatives of antibiotics to promote growth in the pig industry. Among several bacterial species used as probiotic, spore forming Bacillus spp. has been considered as the most appropriate probiotic as its spores can to resist harsh environments, thus enabling extensive storage at ambient temperature....

Introduction: Patho-anatomical lesions are routinely recorded at meat inspection of swine carcasses in Denmark. The original purpose was to safeguard food. For an additional fee, a more thorough post mortem examination of lungs can be performed at the Danish Pig Research Centre (DPRC) with the specific purpose of diagnosing respiratory disorders. However, for the herd manager or veterinarian, it is tempting to use the frequent and free-of-charge recordings from the meat...

Introduction: Consumers and important trade markets value meat without residues of antimicrobials. Preventive actions taken by the vet and the farmer are therefore essential to prevent presence of residues. This includes careful registration of use of antimicrobials, marking of treated animals, and compliance with withdrawal periods. Moreover, surveillance (own check and official samples) is needed to detect enough cases to encourage compliance. To identify causality,...

Introduction: Pork head meat, cheek meat, lymph nodes, and other carcass by-products may become contaminated with Salmonella in pork slaughter facilities. In a preliminary survey, a large pork processing plant in the United States was sampled bimonthly from January to July of 2015 to determine the prevalence, seasonality, and serotype diversity of Salmonella enterica (SE) isolated from cheek meat and head trim of swine carcasses. Materials and...

Introduction Improvest ® (Zoetis, Kalamazoo, MI) is immunological product for intact male pigs that stimulates the production of antibodies against gonadotropin-releasing factor (GnRF), blocking its activity and causing temporary castration. It was approved for use in the United States in 2011 (FDA 2011). Improvest management delays castration, taking advantage of increased feed efficiency and lean gain of intact male pigs (Dunshea et al. 2001; Boler et al. 2011),...

INTRODUCTION The swine slaughtering process is affected by practices that go from the establishment of fasting on the farm to the slaughtering stage in the slaughterhouse. Animals are subjected to practices that will directly reflect on the quality of their carcass, and on how meat cuts will be ranked as more or less valuable in the market. Thus, pre-slaughter phases are fundamentally relevant to the quality of the final product, once they affect the living experience of animals...

Introduction Parasites have long been neglected but nowadays are becoming more recognized as important foodborne pathogens. Various factors contribute to their undervaluation such as complex lifecycles and transmission routes, prolonged incubation period and chronic disease manifestations. In addition, rapid and sensitive diagnostic assays are not always available and therefore parasite occurrences are often underreported, resulting in low disease...

1. Introduction The global demand and industrial production of pork and pork products are increasing. According to the Food and Agriculture Organization of the United Nations (FAO) statistics, worldwide swine production has increased steadily from 1961 to 2007, with Asia the continent with the highest production with around 50% of the total worldwide production. Between 2007 and 2017, production increased significantly in Asia and remained as the highest swine producers (almost...
