“…Balance between antioxidants and pro-oxidants, such as PUFA concentration or free iron influence the oxidative stability of meat (Kanner 1992, Florek et al 2012. Although there were significant differences between groups in the PUFA percentage, neither gender nor castration practice had significant effect on the lipid oxidative stability of the analyzed meat, expressed as TBARS value.…”

This study was carried out on the farm specializing in organic pig production on 80 fatteners of the Polish native Pulawska breed, allocated into 4 groups (20 pigs each): EM -entire (uncastrated) males, IM -immunocastrates -males vaccinated with Improvac ® , CM -surgically castrated males and G -gilts. The highest average daily gains were achieved by the IM group, slightly lower by EM, whereas the lowest by CM and G groups. Content of polyunsaturated fatty acids (PUFA) in intramuscular fat and backfat (10.19% and 10.68%, respectively) of IM was lower (P ≤ 0.05) than in fat of EM (11.4% and 13.20%, respectively), but higher (P ≤ 0.05) in comparison to CM (8.43% and 8.71%, respectively). Vaccination of boars against GnRH has not decreased quality traits of organically produced pork. Furthermore, comparing to meat from surgically castrated males, it resulted in better qualities (lower fat content in carcass, higher PUFA level in fat, better physicochemical meat properties).

“…The yield and quality of edible animal by-products depend on multiple interactive factors of genotype (breed), sex, animal species, production system (feedlot or pasture-based system), physiological and health condition of the animal, age, weight, post-mortem handling and processing [45]. Florek et al [45] reported that variation in weight of the by-products is due to differences in animal weight at slaughter, indicating that animal of the same breed and species with high body weight gain will produce more kilogrammes of by-products than those with low body weight.…”

Abstract:The consumption of animal by-products has continued to witness tremendous growth over the last decade. This is due to its potential to combat protein malnutrition and food insecurity in many countries. Shortly after slaughter, animal by-products are separated into edible or inedible parts. The edible part accounts for 55% of the production while the remaining part is regarded as inedible by-products (IEBPs). These IEBPs can be re-processed into sustainable products for agricultural and industrial uses. The efficient utilization of animal by-products can alleviate the prevailing cost and scarcity of feed materials, which have high competition between animals and humans. This will also aid in reducing environmental pollution in the society. In this regard, proper utilization of animal by-products such as rumen digesta can result in cheaper feed, reduction in competition and lower cost of production. Over the years, the utilization of animal by-products such as rumen digesta as feed in livestock feed has been successfully carried out without any adverse effect on the animals. However, there are emerging gaps that need to be further addressed regarding the food security and sustainability of the products. Therefore, the objective of this review highlights the efficacy and effectiveness of using animal by-products as alternative sources of feed ingredients, and the constraints associated with their production to boost livestock performance in the industry at large.
