“…The chemical composition of soybean meal had only the contents of CP and MM changing depending on the seasons (Table 3). Despite variations, the obtained values are similar to those found by Rieger et al (2008), who studied the composition of soybean meals of the West and Southwest regions of Paraná, and Zambom et al (2001), who studied the nutritional value of feed for ruminants in the North West of Paraná. The CP, however, showed variations depending on the seasons, but these variations are not due specifically to climatic conditions, but rather to the origin of the grains used for bran production (Grieshop et al, 2003) and the shell proportion added to the bran (Zambom et al, 2001).…”

-The objective of the present study was to characterize the food sources, as well as the composition and quality of milk obtained from household farms of western Paraná State (Brazil) with and without technical assistance during the different seasons. For such, 24 properties were selected, 12 of which only received assistance and technical support. Four milk samples were taken (summer, autumn, winter and spring) to assess the physicochemical composition, somatic cell count and total bacterial count and feed supplied to the animals to assess the chemical composition (crude protein, ash, dry matter and neutral detergent fiber). The data were analyzed in a completely randomized design with a 2 × 4 factorial arrangement; the first factor was the presence and absence of technical assistance and the second factor was the four seasons of the year. Due to the dairy tradition of properties in the region, technical assistance had no significant effects on the health and nutritional quality of food, the number of animals, the production, or total bacterial count, which suffered oscillations only depending on the seasons of the year. However, the presence of assistance contributed to reducing somatic cell counts of milk produced and marketed. The technical assistance does not affect the quality of forages and concentrates used or the milk composition; however, it improves the sanitary quality of the milk produced throughout the four seasons of the year in household farms of western Paraná.

“…Regarding the NDF, ADF and CF, variation was also observed between the SBM studied and, according to Rieger et al (2008), NDF is an estimate of the amount of carbohydrates of low digestibility to non-ruminants, including soybean hull and nonstarch polysaccharides. The fiber content of SBM is influenced by adding lower or higher amounts of soybean hulls, as well as the amount of CP.…”

The aim of this study was to evaluate equations to predict the metabolizable energy (ME) of soybean meal (SBM) for swine. Seven SBM were used, which were analyzed for dry matter, crude protein, ether extract, neutral detergent fiber (NDF), acid detergent fiber (ADF), ash, calcium, phosphorus, solubility in potassium hydroxide (KOH) and urease index. To determine the ME of SBM, 32 barrows, with an average initial weight of 29.01 ± 3.64 kg, were used and distributed in a randomized blocks design, with seven treatments and four replicates. To validate the prediction equations, linear regression models were adjusted, using observed values of ME (metabolism trial) as a function of the estimated ME (obtained by applying the chemical composition of the SBM in selected equations found in the literature). The existence of regression was evaluated by the "t" test, partially applied to each parameter (β 0 and β 1 ). The validation of the prediction models of first degree was obtained by accepting the joint null hypothesis β 0 = 0 and β 1 = 1. The equations ME = 5.42 -17.2FDN -19.4MM + 0.709GE and ME= 1099 + 0.740GE -5.5MM -3.7NDF are effective for estimating the ME of SBM for growing pigs. Key words: Chemical composition, linear regression, validation ResumoObjetivou-se com este trabalho avaliar equações para predizer a energia metabolizável (EM) do farelo de soja (FS) para suínos. Foram utilizados sete FS, os quais foram submetidos às análises de matéria seca, proteína bruta, extrato etéreo, fibra em detergente neutro, fibra em detergente ácido, matéria mineral, cálcio, fósforo, solubilidade em hidróxido de potássio (KOH) e índice de urease. Para determinar a EM dos FS foram utilizados 32 suínos, machos castrados, com peso médio inicial de 29,01 ± 3,64 kg. O delineamento experimental foi o de blocos ao acaso com sete tratamentos e uma ração referência, sendo utilizadas quatro repetições. Ajustaram-se os modelos de regressão linear utilizando-se valores de EM observados (ensaio de metabolismo) em função da EM estimada (obtidas pela aplicação da composição química dos FS em equações selecionadas na literatura). A existência da regressão foi avaliada pelo teste t parcial aplicado a cada parâmetro (β0 e β1). A validação da predição dos modelos de 1º grau foi obtida pela aceitação da hipótese de nulidade conjunta β0= 0 e β1= 1. As equações EM= 5,42 -17,2FDN -19,4MM + 0,709EB e EM= 1099 + 0,740EB -5,5MM -3,7FDN são efetivas em estimar a EM do FS para suínos. Palavras-chave: Composição química, regressão linear, validação

“…However, a greater variation was seen in the values of ether extract and fibrous fractions. The variability found for the level of ether extract in the soybean meal is due to the efficiency of the oilextraction process (OST et al, 2005;RIEGER et al, 2008), and may contribute to the variation found in the values of digestible and metabolizable energy. DE: digestible energy (kcal/kg); ME: metabolizable energy (kcal/kg); CP: crude protein (%); EE: ether extract (%); CP: crude fiber (%); ADF acid detergent fiber (%); NDF: neutral detergent fiber (%); MM: mineral matter (%); *significant at 5% probability by t-test (P<0,05); ** significant at 1% probability by t-test (P<0,01)…”
