“…These results were superior to those described by Carvalho et al (2009), who observed values for CEDC of 63.06%, NDFDC of 50.64%, and of CEMC of 58.60%, and lower for ADFDC with 55.71%. The values of digestible and metabolizable energy, respectively, were lower than whole cassava rasp (3,048 and 3,020 kcal kg -1 ) (ROSTAGNO et al, 2011).…”

“…However, the DCC showed higher energy values in relation to the research done by Carvalho et al (2009), using mellow coffee husk (MCH) in swine feed in starting phase, in which they obtained values of 2,352 and 2,186 kcal kg -1 , respectively, for DE and DM.…”

“…The results of the apparent digestibility coefficients (ADC), metabolism coefficient (MC) of the crude energy and digestible nutrients (Table 4) of the dehydrated cassava co-product in starting piglets feeding showed that DMDC values (74.52 %) and OMDC (91.14 %) were higher than those described by Carvalho et al (2009), who worked with mellow coffee husks, fibrous food similar to DCC and obtained DMDC values of 62.64 % and OMDC of 67.87 %. However, they were lower than the values obtained by Silva et al (2008), using cassava root silage without inoculant, with a DMDC of 92.57 % and DCC of 90.04 %.…”

Two experiments were carried out to determine the nutritional value of a dehydrated cassava co-product (DCC) and its effects on the performance and blood variables of piglets fed with different levels of DCC. In experiment I, a digestibility assay was performed and 30 whole-male crossbred piglets with initial body weight of 18.00 ± 0.673 kg were housed individually in metabolism cages and distributed in a completely randomized experimental design with 5 treatments, 6 replicates and one animal per experimental unit. A reference diet was formulated to meet the category nutritional requirements and the different levels of DCC replacement (6, 12, 18 and 24%) were used to replace the reference diet and composed the treatments. In experiment II, 120 piglets (60 whole males and 60 females) were used, with initial body weight of 13.05 ± 1.59 kg, distributed in a randomized complete block design with 5 treatments, 6 replicates and 4 animals per experimental unit. Treatments consisted of five feeds with increasing inclusion levels (0, 3, 6, 9 and 12%) of the DCC. The feed based on corn and soybean meal were formulated to meet the recommended levels in starting piglets feeding. The data were submitted for statistical analysis and, when presenting significant difference, the averages were compared by the Dunnet's test at 10 % significance. In the digestibility assay, the values of DCC's digestive energy and metabolizable energy of 3,022 and 2,984 kcal kg -1 in natural matter, respectively, were found. There was no significant effect (p > 0.10) of inclusion levels of DCC on the final weight and daily gain of weight however we observed a quadratic effect (p < 0.10) of the DCC levels on daily feed intake and feed conversion. For the analysis of blood parameters, the results showed that there was no effect (p > 0.10) of DCC levels on glucose and blood urea in the different treatments. The use of the dehydrated cassava co-product can be an energetic alternative to piglets in starting phase and can be used up to 12 %. Key words: Alternative food. Nutrition. Swine production. ResumoDois experimentos foram conduzidos, objetivando-se determinar o valor nutricional do Coproduto Desidratado de Mandioca (CDM) e seus efeitos no desempenho e nas variáveis sanguíneas de leitões alimentados com diferentes níveis do CDM. No experimento I, realizou-se um ensaio de digestibilidade e foram utilizados 30 leitões híbridos, machos inteiros, com peso vivo inicial de 18,00 ± 0,673 kg, alojados individualmente em gaiolas de metabolismo, e distribuídos em um delineamento experimental inteiramente casualizado, com 5 tratamentos, 6 repetições e um animal por unidade experimental. Uma ração referência foi formulada para atender as exigências nutricionais da categoria e diferentes níveis de substituição do CDM (6, 12, 18 e 24%) foram utilizados para substituir a ração referência, compondo os tratamentos.

“…The following reaction conditions were considered, according to the literature review: 6:1 methanol to fat molar ratio and catalyst amount 1% (w/w). As the mass of fat considered in each reaction was 150 g, the methanol used was 42 mL and the mass of catalyst (NaOH) was 1.5 g at temperature 60° C for about 90 minutes according to (Moreira et al, 2009) Biodiesel yield of each reaction was determined based on the following equation:…”

Fossil fuels are non-renewable sources of energy which generate pollutants and are linked to global warming and climatic change. In order to overcome these problems, there is a need for an alternative for fossil fuels. The most common renewable fuel is biodiesel which is produced from vegetable oils, animal fat wastes and poultry. The aim of the present work was to study the transesterification of liquid fat resulted from chicken roasting. This fat was esterified with methanol and NaOH as a basic catalyst. Product yield of chicken fatty acid methyl Ester (CFME) was 79.1 % for liquid fat resulted from roasting. All quality control parameters for biodiesel produced (B100) were generally in agreement with ASTM standards. It can be concluded that chicken fat resulted from roasting is suitable for low cost feed stocks for biodiesel production.

“…The soybean hulls can be included up to 10 and 12% for growing or finishing pig diets, respectively, replacing the wheat bran on a weight basis without any adverse effects on palatability of diets and animal performances (Chee et al, 2005). However, Moreira et al (2009) not recommend the use of soybean hulls to piglets due reducing daily feed intake and daily weight gain for the animals fed feed containing soybean hull (15% inclusion in the diet) compared to the control feed without soybean hull. Esonu et al (2005) studing laying hens, found that inclusion of up to 20% soybean hulls, improves the Feed cost/dozen eggs, and when cellulolytic enzyme supplementation at 30% dietary level of soybean hull meal in layer diet could not significantly affect the performance of laying hens.…”
