“…Guinea pigs have a wide capacity to utilize different types of food, they make good use of all types of food, from food rich in ber to food rich in protein; even though ber has a lower nutritional value, guinea pigs make better use of it than other monogastric animals by having a functional caecum, generating a lower utilization of nutrients and metabolizable energy, likewise, the protein contribution contributes to the higher utilization of energy, even concentrates and other supplements improve their nutritional contribution when they are included in the diet [4,6,9], seeking to insert and meet the requirements that the market demands, standard guinea pigs of size and quality [10]. In this way, guinea pigs with better live weights could be obtained by feeding alfalfa supplemented with balanced feed, as happened in the present research work.…”

Background The present investigation was carried out to evaluate productive variables (feed intake, feed conversion, and weight gain), cholesterol and triglyceride levels in the blood of guinea pigs fed different feed rations. Methods We worked with 45 male guinea pigs of the Peru breed, weaned at 21 days of age, randomly distributed in three groups of 15 guinea pigs and three replicates each, where the control treatment (T0) was fed only alfalfa, the first experimental treatment (T1) with alfalfa and balanced feed in proportions of 3:1, respectively, and the second experimental treatment (T2) with Ryegrass and balanced supplement, also in a 3:1 ratio. Results At the end of the study (nine weeks), average live weights of T0 = 917.67 g, T1 = 948.13 g, and T2 = 911.60 g were obtained; average feed intake on a dry matter basis (DM) per guinea pig/day was increasing (T0 = 59.3 g, T1 = 60.96 g, and T2 = 65.51 g), with a feed conversion of 6.89, 6.59 and 7.57 for T0, T1, and T2, respectively; likewise, guinea pig live weight gain/day was 8.54 g for T0, 9.13 g for T1 and 8.58 for T2. As for cholesterol, the lowest value was obtained in T0 (40.7 mg/dL), and triglycerides were lower in T2 (54.6 mg/dL). Conclusions The guinea pigs fed with alfalfa and concentrate supplement have a higher weight gain and feed conversion; however, they have high levels of cholesterol and triglycerides in the blood, unlike guinea pigs fed with Rye Grass and alfalfa; the latter had the lowest values.

“…Due to its high fibre content, it may only be suitable as feed for animals able to handle a high fraction of fibres in their feed. Furthermore, a high fibre content may hinder the digestion of the other compounds [113]. Additionally, to the composition shown in Table 5, pods contain compounds such as phenolic compounds which can exhibit among others antimicrobial and radical scavenging effects [99].…”

From harvesting to consumption of the faba bean (Vicia faba), different plant residues such as stems, leaves, pods, and seed husks remain as by-products. The harvest residues constitute about 50% (w/w) of the whole aboveground biomass, while the empty pods and the seed husks account for 11% and 6% (w/w) on average, respectively. Due to the environmental and dietary benefits, the global production of faba beans is most likely to increase in the future. Concomitantly, the amounts of by-products will rise as well. So far, mainly the harvest residues have been widely studied, whereas the pods and husks have received less consideration. Therefore, the aim of this review was to provide an overview of the composition of the faba bean plant residues and to illustrate their potential of being used as feedstock in food, feed, or even non-food applications. This literature survey clearly reveals that all the residual materials of faba beans contain valuable compounds and might be suitable for a multitude of different applications. The residual material should thus not be disposed of but further valorized in order to exploit the full potential of the biomass.

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.
