“…These results are in agreement with those found by Hansen, Rosenlund, Karlsen, Koppe, and Hemre (), Cheng et al () and Ye, Liu, Wang, and Wang () in which the proximate chemical composition did not exhibit any change with different levels of inclusion of plant protein in the diet. However, these results do not corroborate those found by Gaber () and Lovatto et al () in which the levels of inclusion of protein concentrates affected the body composition.…”

“…The lowest FC observed in the fish that were fed the RBPC10 and RBPC15 diets can be explained by the smaller thickness of the fillet (Bonaldo et al, ). Lovatto et al () also found a lower FC in jundiás fed diets containing 250 and 500 g/kg crambe protein concentrate as a substitute for animal protein, which was attributed to the nutritional adaptation of fish to the experimental diets.…”

The aim of this study was to assess the effect of increasing inclusion levels (100, 150, 200 and 300 g/kg) of rice bran protein concentrate (RBPC) in jundiá (Rhamdia quelen) diets using growth, body composition, somatic indices and digestive enzyme activity as parameters. Five isoproteic (370.08 ± 0.04 g/kg) and isocaloric (13.38 ± 0.04 MJ/kg) diets were formulated with four replicates per treatment. After acclimation, 500 jundiá juveniles (initial mean weight of 6.28 ± 0.12 g) were distributed into 20 round polyethylene tanks (280 L) (25 fish per tank) coupled to a thermoregulated water recirculating system. The fish were fed experimental diets three times daily (at 9:00, 13:00 and 17:00 hr) to apparent satiation. At the end of the trial (45 days), no significant differences were found in the body chemical composition, somatic indices, and trypsin and chymotrypsin enzymes of the fish fed experimental diets. A lower final weight and a lower condition factor were found in fish fed diets RBPC10 (100 g/kg of RBPC) and RBPC15 (150 g/kg of RBPC). Based on the results of this study, it is clear that the use of RBPC (at high dietary inclusion levels of 200 and 300 g kg−1) is an effective alternative protein source to fishmeal.

“…A utilização de farelo de crambe na alimentação animal vem sendo estudada principalmente para ruminantes como bovinos de corte (Mendonça et al, 2015), bovinos de leite (Oliveira et al, 2016) e ovinos (Goes et al, 2010;Dorigon e Gai (2016), entretanto, são escassos os estudos para os não ruminantes, havendo alguns trabalhos com juvenis de jundiá (Lovatto et al, 2014;Pettro et al, 2014), tilápias do Nilo (Moura et al, 2015) e frangos de corte (Ledoux et al, 1999). Portanto, objetivou-se com o presente trabalho determinar o desempenho de frangos de corte na fase inicial de vida, alimentados com farelo de crambe como fonte proteica para a ração.…”

Alimentos alternativos. Fatores antinutricionais. Fibra bruta.resUMo Um experimento foi conduzido com o objetivo de avaliar a substituição da proteína da ração pela proteína do farelo de crambe (Crambe abyssinica) sobre o desempenho dos frangos de corte na fase inicial (oito a 21 dias). Foram utilizados 420 pintos machos da linhagem Cobb 500®, distribuídos em delineamento experimental inteiramente casualizado com cinco tratamentos e quatro repetições de 21 aves por unidade experimental. Os tratamentos experimentais constituíram de uma ração testemunha sem o farelo de crambe e os demais pela substituição da proteína da ração nos níveis de 5, 10, 15 e 20%. Não houve efeito significativo para conversão alimentar dos frangos, no entanto, observou-se efeito linear decrescente para o consumo de ração e o ganho de peso das aves, à medida que a proteína do crambe substituiu a proteína da ração. Verificou-se redução do consumo de ração aos níveis de 10, 15 e 20% de substituição da proteína. Para o ganho de peso, os menores valores observados foram para os níveis de 15 e 20% de substituição, enquanto que os níveis de 5 e 10% não diferiram em relação ao tratamento testemunha. Portanto, recomenda-se a substituição do farelo de crambe na ração até o nível de 10% por não influenciar negativamente no ganho de peso dos frangos de corte.inforMation Cronología del artículo. Recibido/Crambe (Crambe abyssinica) meal in diets for broilers chickens sUMMarY A experiment was conducted to evaluate the substitution of the crude protein from the ration for the protein from crambe (Crambe abyssinica) meal on the performance of broilers in starter phase (eight to 21 days). A total of 420 male chicks of the Cobb strain were used, distributed in a completely randomized design, with five treatments and four replications of 21 broilers each. The experimental treatments consisted of a control diet without the crambe meal and other substitution of protein from ration for crude protein from crambe meal in levels of 5, 10, 15 and 20%. There was no significant effect for the feed conversion of the chickens, however, there was a decreasing linear effect for feed intake and weight gain of the birds, to the extent that crambe protein replaced the protein ration. A Reduction in the feed intake at 10, 15 and 20% levels of protein substitution was observed. For the weight gain, the lowest values observed were for the 15 and 20% replacement levels, whereas the levels of 5 and 10% did not differ in relation to the control treatment. Therefore, it can be recommended to replace the crambe meal in the feed level of 10% without negatively influencing the weight gain of broilers. additional keYwordsAlternative foods.

Effects of phosphorylated protein concentrate of pumpkin seed meal on growth and digestive enzymes activity of silver catfish (Rhamdia quelen)

et al. 2016

The present study aimed to determine the growth and activity of proteolytic digestive enzymes of silver catfish (Rhamdia quelen) fed by replacing increased fish meal in the diet by either phosphorylated protein concentrate or pumpkin seed meal (PPCPS). Five experimental diets were formulated with levels: 0 (control), 25 (25% pumpkin seed meal (PSM) and 25% PPCPS) and 50% (50% PSM and 50% PPCPS). Crude protein from fish meal was replaced either by PSM or PPCPS crude protein. Each diet was fed to four replicate groups of silver catfish (initial weight 24 ± 0.46 g) to apparent satiation three times a day. Four orthogonal contrasts were applied to the biological assay data. When compared to other diets, the replacement of fish meal by either 25% or 50% of PPCPS in the diet of juvenile catfish does not change growth rates and promotes improvement in feed conversion. The use of PSM as a protein ingredient is not recommended due to its negative influence on fish growth. Thus, it can be concluded that the nutritional value of PSM can be improved by the simple chemical process of phosphorylation, yielding a protein concentrate (PPCPS) that may be used as a promising alternative ingredient.
