“…Food waste could be a substitute for part of cereal grains and plant protein sources used in animal nutrition, which would alleviate food competition between humans and animals [23]. Additionally, feed costs represent a significant component in meat production and it impacts financial gains [24]. Feed costs range from 55% to 72% of total pig production costs in the EU [25,26] and from 55% to 75% of the total poultry production costs [24].…”

Bioactive compounds are substances which are present in foods in small amounts and have the ability to provide health benefits. Bioactive compounds include but are not limited to long-chain polyunsaturated fatty acids, vitamins, carotenoids, peptides, and polyphenols. The aim of the present study is to review literature for potential bioactive compounds present in food waste material and discuss the transformation of food waste to animal feed under the perspective that usage of food waste, rather than disposal, may tackle food insecurity and provide health benefits. Finally, applications in poultry and swine nutrition, with emphasis on the presence of fatty acids on food waste material, are discussed.

“…Recycling food waste into poultry feed is a feasible solution that would help to address issues associated with food security, waste management, environmental challenges, and resource scarcity while alleviating competition for food between animals and humans [9,16,17]. Additionally, incorporating food waste into poultry feed may help to reduce feed cost and increase production efficiency, as feed cost accounts for 55 to 75% of the total production costs in poultry farming and the cost to manufacture recycled food waste is generally lower than conventional feed ingredients [18,19].…”

This study explored feeding recycled food waste-based diets for gut health, nutrient digestibility, bone morphology, and bone mineral level in laying hens. Hy-Line Brown laying hens (n = 150) were randomly allocated to three experimental treatments consisting of a commercial control diet, a recycled food waste-based diet, and a 50:50 blend of the control and food waste-based diets, with 50 replicates of a single bird per cage per treatment from 24 to 63 weeks of age. Egg production was recorded daily and feed intake was measured weekly. The gut pH, jejunal and ileal morphology, nutrient digestibility, bone morphology, and mineral composition were measured at 63 weeks of age. Hens on the food waste-based treatment had similar egg production but lower feed conversion ratio (FCR, 1.948 vs. 2.172 kg feed/kg egg, p < 0.001) and higher ileal pH (p < 0.001) and bone ash content (p < 0.001) compared to birds on the control treatment. Moreover, hens fed the food waste-based diets had higher ileal digestible energy (p < 0.001); ileal energy digestibility (p < 0.01); tibia S, Fe, Mn, and Zn levels (p < 0.05); and Mg, K, S, Mn, and Mo digestibility (p < 0.05) compared to hens fed the control diets. Hens offered the 50:50 blend diets had higher tibia P, Mg, and Mo levels (p < 0.05) and higher Ca digestibility (p < 0.05) compared to those fed the control diets. Thus, feeding recycled food waste-based diets is effective to improve laying performance, nutrient digestibility, and bone mineralization in laying hens.

“…Feed expenses play a sizable role in the production of meat, and they affect profits. Feed costs range between 55% and 75% of total poultry production costs (Franco & Pearl, 2000). Food waste accounts for a significant portion of wasted resources (Food and Agriculture Organization [FAO], 2019), particularly nutrients.…”

This study was conducted to investigate the effect of dried cafeteria leftover food (DCLF) incorporation in growing APRI rabbit diets on nutrient digestibility, live body weight, body weight gain, carcass traits, meat quality, blood parameters, and economic efficiency. Thirty‐six APRI rabbits (6 weeks of age), after weaning, were randomly divided into three groups (12 rabbits/group, 613 ± 5 g). During the experiment, rabbits aged 6–14 weeks participated in the experiment. An approximate isocaloric and isonitrogenous composition was achieved in three pelleted experimental diets. For the rabbit groups D1 (as the control), D2, and D3, DCLF was added at doses of 0%, 17.5%, and 35%, respectively. Digestibility trails were carried out at the end of the feeding experiment to evaluate the nutritional and feeding values of the experimental diets. To examine the characteristics of the carcasses, the quality of the meat, the histopathological analysis, and the blood plasma parameters, three rabbits were slaughtered from each group. The results showed that the feeding values (TDN and DE), which had the greatest values, as well as the digesting coefficients for dry matter, organic matter, crude fiber, and ether extract between the D1 and D3 groups were significantly different (p < 0.05). On the contrary, the curde protein, nitrogen‐free extract, and digestible crude protein of the examined diets showed no signifcant differences compared with the control diet. The level of DCLF incorporation in diets significantly (p < 0.05) increased the live body weight at 14 weeks; with D3 recording the highest values (2130.9 g) when compared to the D1 and D2 groups. A similar pattern was observed for both daily increase and total body gain (6–14 weeks). Feed conversion recorded insignificant differences among the experimental diets respecting the period 6–14 weeks of age. DCLF levels had a significant effect on dressing and giblet percentages. The chemical composition and color parameters of rabbit meat were similar (p > 0.05), except for fat%, which had the highest value in the D3 group (p < 0.05) compared to the D1 and D2 groups. Economic efficiency was improved by using DLCF up to 35% in terms of gross margin and feed cost/kg gain. In conclusion, using DCLF in the feeding system of rabbits could enhance productive performance, carcass traits, meat quality, and physiological function, as well as improve economic efficiency.
