Use of poultry pre-cooked slaughterhouse waste as ruminant feed to prevent environmental pollution

Abstract

The generation of poultry slaughterhouse waste from poultry production is not only unavoidable but the amount and kinds of waste can cause environmental problems. In the present study, the potential rumen digestion of poultry slaughterhouse waste which consists of protein-rich organic residues was evaluated. The chemical composition, amino acid profile and Cornell Net Carbohydrate and Protein System fractions of these wastes was determined. Rumen digestion of poultry slaughterhouse waste was compared with two common protein sources (fish meal and roasted soybean). Three poultry slaughterhouse waste samples were collected from industrial poultry slaughterhouses and the in situ degradation was done using rumen cannulated sheep. The protein (50e63%), ether extracts (18e27%) and ash (9e15.5%) contents of different poultry slaughterhouse waste samples were different (P < 0.05). Methionine and lysine contents were similar among different poultry slaughterhouse waste sources. Difference were observed for cystine (1.2e1.7%), threonine (1.9e2.2%), arginine (3e3.5%), leucine (3.5e4.1%) and valine (2.8e3.3%) (P < 0.05). Ruminal degradation rate for dry matter, organic matter and protein were different among poultry slaughterhouse waste, fish meal and roasted soybean. The degradation parameter for protein degradation was 76% for poultry slaughterhouse waste, 79% for fish meal and 98% for roasted soybean (P < 0.05). Results revealed that there was great variation in chemical composition, protein fractioning, and amino acid profiles of different poultry slaughterhouse waste sources. Poultry slaughterhouse waste is slowly-degraded protein in the rumen and thus can be an economical and rich source of rumen undegradable protein in ruminant nutrition. This implies that the use of poultry slaughterhouse waste in ruminant nutrition has a huge potential as a cleaner product of animal feeding and prevention environmental pollution. However, further studies are warranted to evaluate the digestibility of poultry slaughterhouse waste amino acids escaping the rumen into the intestine in ruminants and to compare the biological values for the amino acids in these waste material with common ruminant feedstuffs.

Organic waste utilization and urban food waste composting strategies in China - A review

“…The most important food waste resources which have potential to convert to food waste to animal feed are household and catering food waste, kitchen and food factory waste, household and catering food waste, manufacturing food waste, retail food waste, compared banana chicken, lettuce, beef, bread waste (Takata et al, 2012;Tufvesson et al, 2013;Vandermeersch et al, 2014;Salemdeeb et al, 2017). Kazemi-Bonchenari et al (2017) concluded that poultry slaughterhouse waste has a considerable amount of essential amino acids, which can be used in ruminant nutrition has a huge potential as a cleaner product of animal feeding and prevention environmental pollution. Alternative feeding method may be helpful to utilize the innovative feeds and alternative protein feeds can contribute to ecological poultry production which has important function under certified organic standards (Fanatico et al, 2018).…”

Valorization of Agro-Industrial Residues: Bioprocessing of Animal Fats to Reduce Their Acidity

“…In rendering, the animal residues are dried, yielding a fat and a protein meal [1]. These co-products may have several potential applications, such as electricity and heat generation [5], biofuel production [6], biopolymers [7], olefins [8], fertilizers [9], biochar [10], or bioflocculant [11], and/or other value-added products such as ingredients for livestock feed [12] or nutritional supplements [13]. Moreover, rendering of animal residues can significantly contribute to the 2030 UN Agenda for Sustainable Development [14], particularly to the UN sustainable development Goal 12 of responsible consumption and production, by promoting and facilitating the efficient use of natural resources throughout their life cycle and sustainable management, minimizing negative impacts on human health and environment, substantially reducing waste generation, and contributing to a more circular economy [15].…”

Evaluation of Electrochemical Methods for Poultry Slaughterhouse Wastewater Treatment

“…Poultry slaughterhouse wastewater originates from meat production processes containing high concentrations of organic substances. The produced wastewater is highly polluted and requires treatment before discharging to the environment [1]. The quantity of wastewater discharged from a poultry plant operations is estimated to be from 20 to 40 L per bird, with 25 L being a typical value [2].…”
