“…Essa redução na digestibilidade da dieta também foi observada na presente pesquisa. No entanto, Hess et al (2008) constataram que 9,4% de adição de lipídeos na matéria seca não afetou a digestibilidade da dieta, assim como verificaram Mizubuti et al (2016), quando alimentaram ovinos com torta de crambe, na relação 30:70 de silagem de sorgo e torta de crambe, que continha 17,6% de extrato etéreo. As características dos ácidos graxos presentes nessas dietas podem ter influência nesses resultados.…”

RESUMOObjetivou-se avaliar o consumo, a digestibilidade e o desempenho de ovinos, arraçoados com dietas isoproteicas, contendo 75% de resíduos da agroindústria frutífera (abacaxi, acerola, maracujá e cupuaçu), uma dieta com feno de tifton e 25% de concentrado, em delineamento inteiramente ao acaso. A participação do resíduo de maracujá na dieta proporcionou os maiores níveis de consumo de matéria seca (1170,6g d -1 ) em relação aos resíduos de abacaxi (693,8g d -1 ), acerola (644,2g d -1 ), cupuaçu (452,9g d -1 ) e feno de tifton (962,7g d -1 ), o que se relaciona aos seus níveis de digestibilidade (77,8; 63,1; 59,1; 61,7 e 71,8%, respectivamente). Tal resultado gerou diferenças significativas, destacando-se o resíduo de maracujá quanto à conversão alimentar (8,3), e o ganho médio diário de peso (141,5g d -1 ). Apesar de ter tido a mesma conversão observada para o feno de tifton (13,2), apresentou maior ganho médio diário (75,6g d -1 ). Os demais resíduos apresentaram efeitos sobrepostos, contudo o resíduo de acerola ficou com a pior conversão (51,4) e o menor ganho médio diário (15,6g d -1 ), sendo esse sem diferença em relação ao cupuaçu (23,0g d -1 ). Os resíduos podem ser utilizados como alternativa para a alimentação de ovinos.Palavras-chave: abacaxi, acerola, cupuaçu, maracujá, subprodutos ABSTRATThe objective was to evaluate the consumption, digestibility and performance of the sheep with iso protein diets, with 75% of residues from fruit agro-industries (pineapple, acerola, passion fruit, and cupuassu) and a diet with tifton hay, and 25% of concentrate, in a totally randomized design. The participation of passion fruit residue on the diet provided the highest consumption levels of dry matter (1170.6g d -1 ) compared with the residues of pineapple (693.8g d -1 ), acerola (644.2g d -1 ), cupuassu (452.9g d -1 ) and tifton hay (962.7g d -1 ), which is related to their levels of digestibility (77.85, 63.14, 59.07, 61.68 and 71.83%, respectively). Such a result generated significant differences with emphasis on passion fruit residue regarding food inversion (8.30) and average daily weight gain (141.50g d -1 ), in spite of having the same conversion detected for tifton hay (13.2), it showed a higher average daily gain (75.6g d -1 ). The other residues showed overlapping effects, however, acerola residue showed the worst conversion level (51.4) and the lowest average daily gain (15.6g d -1 ), and this one showed no difference compared with cupuassu (23.0g d -1 ). The residues can be used as an alternative for sheep feeding.

“…A lower intake of DM (kg/lamb/day) and high intake of EE (kg/sheep/day) was observed by Brás et al (2014), who evaluated different co-products from the extraction of oils in sheep diets. However, Mizubuti et al (2016) observed a higher intake of DM and EE in lambs fed diets containing 70% crambe cake and 30% sorghum silage. Goes et al (2018) evaluated four levels of crambe cake (0, 50, 100, and 150 g/kg DM) and observed no effect on DM intake but observed an increase in the intake of EE.…”

The objective was to evaluate different levels of crambe cake protein (0, 250, 500, 750 and 1000 g/kg of DM) to replace soybean meal protein on the intake, apparent digestibility coefficient (ADC), blood glucose, ruminal fermentation, and protozoal population in lambs. Two experiments were performed. In experiment one, 40 crossbred male lambs weighing 20 ± 3.45 kg were used, distributed in a completely randomized design, to study intake and ruminal parameters. In experiment two, 25 crossbred male lambs weighing 23.44 ± 1.04 kg were used to study digestibility. The intake of dry matter and total carbohydrate (TC) (kg/lambs/day and g/kg0.75), crude protein (kg/lambs/day) and final body weight decreased with increase of crambe cake protein as a replacement for soybean meal protein, while e t h e r e x t r a c t ( EE) intake (kg/lambs/day and g/kg0.75) increased. The ADC of EE presented a positive linear effect and the ADC of TC and non-fibrous carbohydrates presented a negative linear effect. There was no interaction within treatments and collection period (0, 3, 6 and 9 h) on ruminal fluid characteristics. Blood glucose presented a quadratic effect for levels of crambe cake protein in diets (max. P = 35.18%), and linear increase for collection period. Ruminal pH showed a quadratic effect for sampling hours (max. P = 5.43 h). For protozoa evaluation, the total amount, Entodinium, and Eudiplodium presented linear decreasing effects with treatment, while Isotricha, Eudiplodium, Ostracodinium and the total amount of protozoa had a linear decrease with sampling hours. Soybean meal protein can be replaced by crambe cake protein at up to 250 g/kg DM.

“…The same was not observed for canola and crambe grains, which presented mean values of 16.78% and 26.46% EE, that is, there was greater use, however, as these grains have a greater amount of total lipids, the recovery was greater. According to Mizubuti et al (2016), it has been observed a reduction in the digestibility of fiber compounds with the addition of lipid sources to the diets and the magnitude of reduction is related not only to the amount, but mainly to the type of fatty acid present in the supplement. In this sense, lipids rich in unsaturated fatty acids tend to cause greater depression in intake and digestibility, due to the toxic effect on rumen microflora, changing the permeability of the cell membrane, reducing the cell ability to regulate intracellular pH and nutrient uptake (Fiorentini et al, 2014).…”

Oilseed grains are used as a protein and energy source, increasing the energy density of the feed. The goal of the present study was to determine the nutritional profile of canola, crambe and soybean grains recovered from feces, and to evaluate the intake and digestibility of nutrients, rumen fermentation parameters of beef cattle receiving whole grains of oilseeds. Three steers, 350 ± 23.5 kg body weight were distributed in a not contemporary, 3 × 3 double Latin square, and fed oilseed grains. Inclusion of crambe grain reduced dry matter intake by 21.02%, with a higher digestibility coefficient for EE and NDF. The crude protein content of canola and crambe grains recovered were similar, but the EE content was higher for the crambe grain (26.46%). Soybean showed the lowest values of chemical composition for grains recovered from feces. The highest dry matter intake (7.86 kg/day), and the lowest NDF digestibility (0.203g/kg), were found for animals fed soybean. The inclusion of crambe grains reduced the rumen ammonia content (10.97 mg/dL); however, the ruminal pH was not altered by the inclusion of grains in the diet. Canola and soybean grains can be included in the cattle diet without altering dry matter intake; while the inclusion of crambe grains reduces the dry matter intake and the ruminal ammonia content of the animals. Crambe grain showed the highest recovery of dry matter and ether extract from feces.
