“…The DM content of the waste was 87.45%, which is close to the 92.24% found by Volpato et al (7) , who evaluated sweet-biscuit waste; the 92.40% determined in biscuit waste by Tardocchi et al (23) ; and the 91.07% found in biscuit waste meal by Corassa et al (11) .…”

“…This value is higher than the minimum and maximum GE contents of 3,200 and 4,485 kcal/kg reported by Corassa et al (11) , respectively. By contrast, Volpato et al (7) described a GE content of 4,494 kcal/ kg in sweet-biscuit waste.…”

“…Some of the alternative feedstuffs are those derived from the food industry. This industry has generated a considerable amount of waste, raising great concern for regulatory agencies in terms of the final destination of this waste, which is commonly discarded in the environment, causing the most diverse environmental problems (6,7) . The biscuit industry is no different, generating large amounts of waste due to inadequacy in the processes of production and distribution to the final consumer that usually stems from losses due to breaking or excess or insufficient cooking during processing.…”

Two experiments were carried out to evaluate the nutritional composition and effect of different levels of inclusion of wafer-type biscuit waste (WW) in the diet of European quail on production performance, carcass yield and economic viability. In the metabolizability trial, WW showed 87.45% DM, 4,128.53 kcal/kg GE, 3,833.14 kcal/kg AME, 3,818.92 kcal/kg AMEn, 9.37% CP and 17% EE. The metabolizability coefficients of DM, GE, EE and CP were 93.20, 92.85, 93.01 and 47.16%, respectively. In the performance trial, feed intake decreased linearly (P<0.05) from 22 to 42 and from one to 42 days of age. Weight gain and feed conversion were not influenced (P>0.05) by WW inclusion. The WW inclusion levels did not influence (P>0.05) carcass yield. The diet with 20% inclusion of WW provided the best financial return. Wafer-type biscuit waste can be included up to the level of 20% in quail diets without compromising production performance, carcass yield or the economic viability of the activity.

“…It is known that the EE content of feed is positively correlated with the GE concentration. Therefore, the higher EE value, the higher will be the GE value (VOLPATO et al, 2015).…”

“…Therefore, some studies have been conducted with new ingredients to determine their nutritional value, the biological response and the economic feasibility of their inclusion in the diets. Agrobusiness co-products have the potential for use in animal feed (VOLPATO et al, 2015). Thus, the need arises for, and it becomes indispensable to the production of pigs, the study of new foods and nutritional strategies that contribute to the better metabolic functioning of the animals.…”

This study was carried out to evaluate the inclusion of two rice co-products in pig feed during the starter phase in terms of the nutritional value and digestibility of the co-products, and the effect on plasma parameters, growth performance and economic viability. In Experiment I, a digestibility assay was performed using 30 barrows (14.4 ± 2.4 kg body weight), which were distributed in a completely randomised design. The co-products studied were broken rice (BR) and hominy rice 3/4 (HR) to replace the reference diet (300 g/kg). The estimated digestible energy (DE) and metabolisable energy (ME) were 3,476 and 3,360 kcal/kg for BR and 3,487 and 3,362 kcal/kg for HR, respectively. In Experiment II, 108 pigs (15.5 ± 1.0 to 30.1 ± 1.3 kg body weight) were used, distributed in a randomised block design with a factorial analysis scheme (2 × 4), using two types of rice and four inclusion levels (160, 320, 480, and 640 g/kg), with six replicates and two pigs per experimental unit. Additionally, a control diet was used with no inclusion of the co-product. The daily weight gain increased and the feed:gain (F:G) ratio decreased as HR content of feed increased. An effect of both types of rice on plasma glucose concentration was obtained, in which the pigs fed with BR showed the highest values. The cost of diet per kilogram of body weight gain increased as BR levels in the diet increased. It was observed that inclusion levels of 480 and 640 g/kg of BR differed from the control diet, showing the highest costs. HR and BR can be used in pig feed in the starter phase at up to 640 g/kg without impairing performance.

The use of residues as substitutes for conventional ingredients in animal feed is a promising alternative able to reduce both costs and environmental pollution. This study aimed to evaluate the viability of using sweet potato vines (SPV) as a replacement for alfalfa hay in diets for growing rabbits. The performance, carcass characteristics, meat composition and metabolic parameters of the liver were evaluated in 30 New Zealand rabbits weaned at 35 days old and an average weight of 900 g. The animals were allotted into three dietary groups: 0SPV, control diet without SPV; 50SPV, diet with 50% replacement of alfalfa hay by SPV; 100SPV, diet with 100% replacement of alfalfa hay by SPV. The animals were slaughtered at 77 days of age. The liver was collected for analysis of glucose and hepatic glycogen and meat samples were collected for analysis of the chemical composition. The data obtained were statistically compared by analysis of variance followed by the Tukey test (0.05). None of the analyzed variables presented differences. It can be concluded, therefore, that SPV may be used as a substitute for alfalfa hay up to 100% in diets for rabbits without impairing the performance and meat composition.
