“…BRUMANO et al (2006) estabeleceram o valor de 2461 kcal de EMAn/kg para o FA quando realizaram um ensaio de metabolismo utilizando frangos de corte com idade entre 41 e 50 dias, valor este significativamente diferente daquele determinado para a idade entre 21 e 30 dias (1963 kcal/kg). SHARMA et al (1978) determinaram um valor de 2601 kcal de EMAn/kg para um FA com 89% de MS, 12,5% de FB e 7,4% de EE, originado por extração controlada via prensa. O FA com 40% PB com valor de EMAn de 3173 kcal/kg de MS não apresentou o ajuste esperado à equação apresentada na Tabela 4.…”

Um experimento foi realizado para determinar a composição química e os valores de energia metabolizável aparente (EMA) e EMA corrigida para nitrogênio (EMAn) de três tipos de farelo de algodão (FA): FA extrusado, FA com extração por solvente com casca e FA com 40% de proteína bruta (PB); duas variedades de sorgo e farelo residual de milho (FRM). Valores de EMAn do FA e do sorgo da literatura foram usados para estabelecer equações de predição através da composição nutricional. Pintos de corte machos Ross (n=210) foram alojados com seis repetições por tratamento e cinco aves por gaiola. Foi utilizada uma ração-referência (RR) e seis rações-teste contendo os ingredientes a avaliar em substituição de 40 % da RR. A composição química dos ingredientes foi:

“…These results are consistent with those reported by Li et al (2012) and Gonzalez-Vega and Stein (2012) who observed a decline in nitrogen and energy digestibility of growing and finishing pigs fed with various sources of cottonseed meal. Free gossypol in cottonseed meal is known to have an inhibitory action on certain enzymes in bird gastrointestinal tract like pepsinogen, pepsin and trypsin by binding with their free epsilon amino groups of lysine, thus reducing protein digestibility (Sharma et al, 1978). However, in this study free gossypol levels were too low (5 to 13 ppm) to induce any detrimental effect on growth performance (Nagalakshmi et al, 2007); but the effect of free gossypol could not be excluded from the reduction of digestibility with cottonseed meal-based diets.…”

Two experiments were conducted to investigate the use of sorghum, cottonseed meal and millet in broiler diets and their interaction when they are used simultaneously. In Experiment 1, a corn-soybean meal control diet was compared with eight experimental treatments based on low tannin sorghum (S30, S45 and S60), cottonseed meal (CM15, CM40) or both ingredients included in the same diet (S30/CM40, S45/CM25 and S60CM15). Results showed that BW gain was not affected by the inclusion of sorghum or cottonseed meal. However, feed intake tended to be affected by the cereal type with the highest values with sorghum-based diets. Feed conversion ratio increased ( P < 0.001) with sorghum-based diets compared with the control diet, whereas a combination of cottonseed meal and sorghum in the same diet did not affect the feed conversion ratio. Significant differences ( P < 0.001) were observed in apparent ileal digestibility (%) of protein and energy with the cottonseed meal and sorghum/cottonseed meal-based diets having lower protein and energy digestibility compared with corn-based diets. In Experiment 2, a control diet was compared with six diets in which corn was substituted at 60%, 80% or 100% by either sorghum or millet and other three diets with simultaneous inclusion of these two ingredients (S30/M30, S40/M40, S50/M50). Single or combined inclusion of sorghum and millet resulted in similar feed intake and growth performance as the control diet. Apparent ileal digestibility of protein and energy was higher with millet-based diets ( P < 0.001). Total tract digestibility of protein in sorghum and millet-based diets tended to decrease linearly with the increasing level of substitution. Sorghum-based diets resulted in lower total tract digestibility of fat compared with millet and sorghum/millet-based diets ( P < 0.001). Higher total tract digestibility of starch were obtained with the control diet and millet-based diets compared with the sorghum-based treatments. Results of the two experiments suggest that broiler growth performance was not affected by the dietary level of sorghum, millet or cottonseed meal. Nutrient digestion can, however, be affected by these feed ingredients.

A study was made to evaluate the protein quality of groundnut cake (GN), mustard cake (MS) and cottonseed cake (CS) and to find a suitable laboratory test for predicting the protein quality of these cakes for chicks. Different oilseed cakes varied considerably in their crude protein, true protein and crude fibre content. The nitrogen solubility was higher in GN (87-7%) followed by MS (78-7%) and CS (60-9%). A similar trend was evident with regard to in vitro protein digestibility. The GN protein was, however, lower in available lysine (2-54%) than MS (3-97%) or CS (3-19%). The albumin, globulin, prolamin and glutelin fractions accounted for 74-1, 57-0 and 48-0% in GN, MS and CS, respectively. The nitrogen solubility, globulin content and modified relative nutritive value (RNV) correlated (P < 0-05) with gross protein value (GPV). The accuracy and precision of various regression equations for predicting the quality of protein in GN, MS and CS are discussed.
