Simultaneous inclusion of sorghum and cottonseed meal or millet in broiler diets: effects on performance and nutrient digestibility

Abstract

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.

Replacement value of cottonseed meal for soybean meal in broiler chicken diets with or without microbial enzymes

“…Batonon-Alavo et al [32] reported that CSM inclusion in diets resulted in a decrease in apparent ileal energy digestibility, but in this trial, the gross energy digestibility was not affected by CSM. In addition, different studies have reported that phytase and xylanase supplementation improved AME [33,34].…”

“…One of the factors that can impede nutrient digestibility and reduce dietary protein utilization is the presence of non-starch polysaccharides (NSP). According to Perez-Maldonado and Australian Egg Corporation Limited [9] the total content of all NSP fractions of commonly used Australian CSM is reported to be as follows (g/kg dry matter): arabinose (37-44), xylose (31)(32)(33), mannose (3)(4), rhamnose (3)(4), fucose (1-1.5), galactose (10)(11), and glucose (40-46). It is well established that supplementing NSP-degrading enzymes, such as β-glucanase, xylanase and pectinase in fibrous diets can potentially lower the intestinal content viscosity and improve digestibility [10,11].…”

Effect of dietary tannins on the performance, lymphoid organ weight, and amino acid ileal digestibility of broiler chickens: A meta-analysis

“…In the present meta-analysis, the deleterious effects of tannins were more obvious when tannins were supplemented at a higher level. Theprevious research has noted the negative effects of high dietary levels of tannins [ 24 ]. For instance, the weight gain and FCR of 42-day-old broiler chickens were impaired when they were fed a diet containing 0.56% and 0.28% tannins, respectively [ 43 , 49 ]; the authors also reported a decrease of aminopeptidase in chickens that were fed a high tannin content.…”

Dietary Selection against Cottonseed Meal by Captive Northern Bobwhites

“…5.0, 7.5, 10.0, 12.5, 15.0 and 17.5%. Batonon-Alavo et al (2016) examined the simultaneous inclusion of sorghum and cottonseed meal in 8-28 day old broiler diets. They observed no change in feed intake between the control diet, a combination of corn and soybean meal, and when cottonseed meal replaced soybean meal alone or in combination with sorghum.…”
