“…As reported by Weremko et al, [18], wheat bran has an extremely higher native phytase activity than the common protein feedstuffs, such as peas, soybean, rapeseed and sunflower meal. Giving that, is possible to suppose that similar differences in native phytase activity may occur also between wheat bran and tobacco seed cake, considering that tobacco and leguminous belongs to the same tassonomic class (Magnoliopsida), different from the wheat's one (Liliopsida).…”

Tobacco seed cake is a by-product with interesting characteristics for animal nutrition, due to its high protein content. The focus of this study is to evaluate if tobacco seed cake, administered in feed, can affect principal serum metabolic parameters of weaned piglets in order to establish if it can be used as both a delivery system of edible vaccines and an alternative protein source in piglets diet. A total of 48 weaned piglets were divided in two homogeneous groups for weight, control (CG) and treatment (TG); TG and CG were fed ad libitum with two isoenergetic and isoproteic experimental diets (CP: 17.68% CG and 17.64% TG) differentiated for the inclusion of 4% of tobacco seed cake in the TG diet in replacement of wheat bran and soybean meal. Growth performances were evaluated and feed intake was measured weekly. Blood samples were collected on days 0, 20 and 43 to evaluate hematocrit and principal metabolic parameters, in order to assess the health status of the animals. The administration of tobacco did not impaire health status and growth performance of piglets. The use of bioenergy co-products from non-food crops may represent a good approach creating an integration between biofuel and food production, with consequent benefits for food security and environmental impact.

RESUMO -Objetivou-se determinar os coeficientes de digestibilidade aparente (CDAP) e verdadeira (CDVP) do fósforo de 11 alimentos de origem vegetal utilizados na alimentação de suínos. Foram utilizados 78 animais mestiços distribuídos em um delineamento experimental inteiramente casualizado, em arranjo fatorial 2 × 2 × 13 (metodologia × fase × tratamento) e três repetições por tratamento (alimento-teste). Os coeficientes de digestibilidade foram avaliados utilizando-se, simultaneamente, duas metodologias (coleta total de fezes e uso de indicador fecal, Cr 2 O 3 ) em duas fases de produção (crescimento e terminação), cada uma com 36 suínos com 25,0 ± 3,0 e 60,0 ± 5,0 kg de peso corporal, respectivamente. Determinaram-se os coeficientes de digestibilidade de 11 alimentos, uma ração-referência e uma ração com baixo conteúdo de fósforo total (0,03%) para estimativa das perdas de fósforo endógeno nas duas fases de desenvolvimento. Os valores médios de CDAP e CDVP do fósforo encontrados com suínos em crescimento e terminação foram, respectivamente, 45,01 e 68,32% para o milho; 31,3 e 66,97% para o sorgo; 31,84 e 41,31% para o farelo de glúten de milho (22% PB); 38,28 e 53,20% farelo de glúten de milho (60% PB); 32,42 e 40,61% para o farelo de algodão (30% PB); 37,50 e 43,95% para o farelo de algodão (40% PB); 50,76 e 55,74% para o farelo de trigo; 38,75 e 52,19% para o farelo de soja; 33,61 e 41,21% para o concentrado protéico de soja; 41,67 e 55,81% a soja integral extrusada e, 56,84 e 66,56% para a levedura desidratada de cana de açúcar. Não foram encontradas diferenças entre os CDAP e CDVP determinados pelas metodologias de coleta total de fezes e de indicador fecal. Na fase de terminação, os coeficientes de digestibilidade aparente e verdadeira dos alimentos testados foram maiores que os obtidos na fase de crescimento.Palavras-chave: coleta total de fezes, fósforo digestível, óxido crômico Phosphorus digestibility from vegetal feed origins determined in growing and finishing pigsABSTRACT -The coefficients of apparent (CADP) and true (CTDP) digestibility of phosphorus of eleven plant feed of vegetal origins commonly used in swine feeds were determined in this research. Seventy eight crossbred barrows were distributed to completely randomized experimental design, with a factorial arrangement 2 × 2 × 13 (methodology × phase × treatment) with three replicates per treatment. The digestibility coefficients were evaluated by using simultaneously both methodologies, total fecal collection and fecal marker (Cr 2 O 3 ), in two production periods, growing and finishing phases, using 36 pigs in each period, with average weight of 25 ± 3 and 60 ± 5 kg, respectively. The digestibility coefficients of 11 feeds, a reference diet and low phosphorus (0.03%) diet were determined to estimate the phosphorus endogenous losses in the two phases.

Bioavailability of P associated with rice bran has been reported to be relatively low with a large variability (12 to 25%), as measured by the apparent digestibility studies and the slope-ratio assay (Jongbloed and Kemme, 1990;Weremko et al, 1997;National Research Council (NRC), 1998). Furthermore, recent studies have suggested that apparent digestibility studies and the slope-ratio assay are limited in assessing true bioavailability of P in feed ingredients for pigs (Fan et al, 2001).…”

The objectives of this study were to determine true phosphorus (P) digestibility, degradability of phytate-P complex and the endogenous P outputs associated with brown rice feeding in weanling pigs by using the simple linear regression analysis technique. Six barrows with an average initial body weight of 12.5 kg were fitted with a T-cannula and fed six diets according to a 6 £ 6 Latin-square design. Six maize starch-based diets, containing six levels of P at 0.80, 1.36, 1.93, 2.49, 3.04, and 3.61 g/kg per kg dry-matter (DM) intake (DMI), were formulated with brown rice. Each experimental period lasted 10 days. After a 7-day adaptation, all faecal samples were collected on days 8 and 9. Ileal digesta samples were collected for a total of 24 h on day 10. The apparent ileal and faecal P digestibility values of brown rice were affected ( P , 0.01) by the P contents in the assay diets. The apparent ileal and faecal P digestibility values increased from 248.0 to 36.7% and from 235.6 to 40.0%, respectively, as P content increased from 0.80 to 3.61 g/kg DMI. Linear relationships ( P , 0.05), expressed as g/kg DMI, between the apparent ileal and faecal digestible P and dietary levels of P, suggested that true P digestibility and the endogenous P outputs associated with brown rice feeding could be determined by using the simple regression analysis technique. There were no differences ( P . 0.05) in true P digestibility values (57.7^5.4 v. 58.2^5.9%), phytate P degradability (76.4^6.7 v. 79.0^4.4%) and the endogenous P outputs (0.812^0..096 v. 0.725^0.083 g/kg DMI) between the ileal and the faecal levels. The endogenous faecal P output represented 14 and 25% of the National Research Council (1998) recommended daily total and available P requirements in the weanling pig, respectively. About 58% of the total P in brown rice could be digested and absorbed by the weanling pig. Our results suggest that the large intestine of the weanling pigs does not play a significant role in the digestion of P in brown rice. Diet formulation on the basis of total or apparent P digestibility with brown rice may lead to P overfeeding and excessive P excretion in pigs.
