“…of the CM (Kong and Adeola, 2014). In these calculations, it is assumed that the indigestibility of BM is the same in diets with 15 and 20% CM (Kassa, 2019;Castro-Bedriñana et al, 2020). Table 1 shows an example of the mathematical calculation of the digestibility of the experimental feed.…”

“…The CP and EE content of MC on a dry basis was above the protein content of the sh meal, blood meal, meat meal, and earthworm meal (Hussain et al, 2011;Gunya et al, 2016;Castro-Bedriñana et al, 2020), and could be a potential substitute for ingredients traditionally used as a protein source in animal diet, having to continue comparative studies at the amino acid level because the main protein in CM would be collagen) (Gauza-Włodarczyk et al, 2017).…”

“…These wastes, after proper processing, could be reincorporated into the production chain, making production systems more sustainable (Schader et al, 2015;Sivaram and Barik, 2019;Omoloso et al, 2021). Among these strategies, the production of unicellular proteins has been proposed from residues, protein isolates and hydrolysates, co-products of the biofuel industry (Makkar et al, 2018), earthworm meal and other residues (Castro-Bedriñana et al, 2020), other residues from the animal industry that are incorporated into other productive subsystems must be identi ed, such is the case of the leather industry, which generates different residues (Kanagaraj et al, 2015;Omoloso et al, 2021). For every ton of bovine leather, 200 kg of usable leather is obtained, the waste includes 250 kg of solid waste free of contamination and without chemical products, 200 kg of tanning waste and 50 tons of wastewater (Hüffer and Taeger, 2004) that must be properly treated.…”

The digestibility of dry matter (DM), crude protein (CP), ether extract (EE), and the concentration of digestible energy (DE) and metabolizable energy (ME) of bovine cheek meal (CM), included in 15 and 20% were compared. The bovine cheeks not chemically contaminated, prior to the pre-tanning stage of the hides, were collected, washed, cooked, dried, and ground for their nutritional evaluation. As the CM cannot constitute 100% of the guinea pig diet, to estimate its digestibility the indigestibility coefficients of a reference diet (Barley meal-BM) were used and assuming that the indigestibility of the BM is the same in the diets with 15% and 20% CM the digestibility of CM was estimated. Twelve six-month-old male guinea pigs were used, divided into three groups of four animals per group, housed in individual metabolic cages for the total collection of urine-free feces. The DM, CP and EE digestibility’s of CM-15% and CM-20% were 72.30, 95.71 and 78.34%, and 76.34, 96.03 and 82.37%, and the DE and ME contents were 4089.5, 3353.8 and 4129.0 and 3385.8 (P < 0.05). The results would indicate that the production of CM would be a viable option to obtain a protein meal of high nutritional value for feeding guinea pigs and could totally replace other less available and expensive protein sources, such as fish meal or soybean meal, contributing to sustainable animal production and with environmental decontamination strategies.

Biowaste from slaughterhouses can be recovered to benefit food security and reduce contamination potential. More than 3 billion heads of livestock are consumed worldwide, which will increase by 17% by 2028, generating more biowaste, increasing infectious agents, and causing economic losses due to circular economy principles not being applied. This work evaluated the nutritional quality of four types of biowaste from bovine slaughter which were transformed into a meal for guinea pigs (rumen content (RCM), ears (EaM), blood (BM), and cheeks (CM)) according to their chemical composition, digestible components, energy contribution, and voluntary consumption. For the animal model, adult male guinea pigs were arranged in metabolic cages for feces collection without urinary contamination. Nine guinea pigs were used in each digestibility test. First, a direct digestibility test was conducted using a meal of barley as a reference diet (RD), the indigestibility coefficient of which allowed for the estimation of the digestibility of biowaste meals through indirect calculations; for this, diets composed of 80% of the RD and 20% of the corresponding biowaste meals were evaluated. The difference method was suitable for determining the digestibility of beef biowaste using the indigestibility coefficients of the reference diet to calculate the digestibility of ingredients which could not be offered as 100% of the meal but were incorporated as 20%. The digestible protein and metabolizable energy contents of RCM, EaM, BM, and CM were 10.2% and 2853 kcal/kg, 44.5% and 3325 kcal/kg, 70.7% and 2583 kcal/kg, and 80.8% and 3386 kcal/kg, respectively. The CM and BM feeds had the highest contributions of digestible protein due to their higher nitrogen content, and the CM and EaM feeds had the highest ME contents due to their higher fat contents. The biowaste meal consumption in descending order was CM > RCM > EaM > BM, which were consumed without problems. These results are indicative that these components can be part of guinea pigs’ diets, and it is recommended to continue studies into guinea pig growth and fattening diets with different levels of these biowaste meals.
