“…Differences in post-mortem glycolysis also result from the different physiological role of internal organs, and thus from the biochemical processes therein (Loeffler and Gäbel, 2018). According to Spooncer (1993), physiological activity in offal tissues adversely affects sensory quality during storage, therefore even chilled offal has a short shelf life of 2-3 days. Zhou et al (2015) concluded that housing system (deep-litter system and concrete-floor system) had no influence on the physical parameters, including pH and WHC, of pork, but there are no studies relating to the effect of the housing system on offal quality.…”

The objective of this study was to comparatively analyse the physical parameters, basic chemical composition and the macro- and microelement content of offal obtained from fattening pigs raised in deep litter and slatted floor housing systems. The experiment involved a group of 80 Puławska fatteners, including 40 pigs kept in deep-litter pens (group I) and 40 pigs in slatted pens without bedding (group II). Offal (tongues, kidneys, hearts, lungs and livers) were evaluated for weight, physical characteristics (pH45, pH24, WHC), chemical composition (water, protein, fat) and the content of minerals: macro- (K, Na, Mg, Ca) and microelements (Zn, Fe, Mn, Cu). Based on the results obtained, associations were found between housing system and basic chemical composition of some offal, i.e. percentage of water (slatted floor<deep litter) and protein (slatted floor>deep litter) in lungs, content of protein (slatted floor>deep litter) and fat (slatted floor<deep litter) in liver, and content of fat in heart (slatted floor<deep litter). The amount of macro- and microelements was significantly differentiated by the housing system with regard to the kidneys: potassium, magnesium, calcium and manganese (slatted floor<deep litter), sodium (slatted floor>deep litter); lungs: sodium (slatted floor>deep litter), potassium (slatted floor<deep litter); and liver: iron (slatted floor>deep litter) and copper (slatted floor<deep litter). In general, the housing system of fattening pigs modified the physical parameters and chemical composition of the analysed offal.

“…The use of animal by-products varies globally, influenced by customs, traditions, culture, and religion [ 14 , 53 ]. The designation of offal as “variety meat” avoids unfavorable associations in consumers related to an edible part of a slaughtered animal other than skeletal muscle [ 54 ].…”

The global increase in demand for meat leads to substantial quantities of by-products, including edible offal from both wild and domesticated animals raised for diversified consumption products within an agricultural framework. Information on the nutritional value of offal is scattered and limited. This review aims to synthesize scientific publications on the potential of offal as a source of nutrients and bioactive substances in human diets. The literature review included publications available in ISI Web of Science and Google Scholar published between 2014 and 2024. Findings indicate that edible offal is characterized by a nutrient concentration often surpassing that found in skeletal muscle. This review discusses the yield of edible offal and explores factors influencing human consumption. Selected factors affecting the nutritional value of offal of various animals and the importance of individual nutrients in ensuring the proper functioning of the human body were analyzed. The optimal use of offal in processing and catering can significantly benefit aspects of human life, including diet quality, food security, and conservation of natural resources.

“…The majority of offals have the capacity to be used as human food, but this capacity can only be achieved if the offals are gathered hygienically, examined, and certified fit for human consumption before being cleaned and prepared properly (Hoffman and Cawthorn 2014). Inedible offal is either burned or buried, processed into tallow and beef meal, or, if appropriate, utilised as pet food (Spooncer 2003). The offals that were hygienically collected in the current study were the head, blood, tail, liver, lungs, intestine, spleen, kidney, heart, and hooves.…”

A study was conducted on profitable rearing of Large White Yorkshire breed of pigs for the purpose of meat, in Puducherry, a union territory in Southern India with predominately hot and humid climate. A total of four pigs were reared for a period of 90 days in the pig sty unit of the Livestock Farm Complex, Rajiv Gandhi Institute of Veterinary Education and Research, (RIVER) Puducherry. During the study period, the average body weight gain was 40 kg. The live weights of the four pigs were (i) 50.4 kg (ii) 53 kg (iii) 44 kg (iv) 55 kg. The cumulative feed conversion ratio recorded was 3.165. An average dressing percentage of 71.44% was obtained from the slaughter of the pigs. The data obtained in the current study may be useful as reference values for the scientific pork production as potential entrepreneurship opportunity, as this is the first study of its kind in Large White Yorkshire pig.
