“…The observed protein mean values were similar to those found by Mabelebele, Siwela, Gous and Iji (2015) in the grains of grain production hybrids, which ranged from 81 to 95 g kg -1 . Albuquerque, Pinho, Rodrigues and Brant (2011) studied different sorghum cultivars and found ADF values between 288.3 and 383.7 g kg -1 .…”

The objective of this study was to identify the hybrids of sorghum most suitable for the production of silage in the semiarid regions of northeastern Brazil. Twenty-three hybrids were evaluated in a randomized block design with three replicates. The dry mass yield; dry mass of leaf, stem, panicle, grains, and senescent matter; and chemical composition of the plant were evaluated. The pH, ammoniacal nitrogen (N-NH3), and chemical composition of the silage were also assessed. The hybrids 947252, FEPAGRO 18, 12F042226, and SF 11 performed best in terms of morphological characteristics, with the highest mass of leaves and grains. The hybrid FEPAGRO 19 had the highest dry matter value (443.3 ± 17.0 g kg-1), whereas the hybrid 12F042496 had the lowest value (271.3 ± 17.0 g kg-1). The dry matter (DM) content of the other hybrids was within the recommended values for silage production (280 to 400 g kg-1). High levels of crude protein were observed in the grouped hybrids 12F042496, 947254, and 12F042422. The hybrid 12F042496 had the highest neutral detergent fiber content. The hybrids 9929036, 9929030, 9929012, 947254, 947072, PROG 134 IPA, 12F042226, 12F042422, and BRS 506 had pH values ranging between 3.8 and 4.2, indicating good quality silage. Overall, the sorghum hybrids 9929030, 12F042224, 12F042150, FEPAGRO19, and FEPAGRO11 had the best growth and production characteristics, and plant and silage chemical composition, and are thus recommended for the production of silage in the semiarid of northeastern Brazil.

“…Maize is high in energy compared with other cereal grains and has multiple uses, but maize production requires higher water supply, so its use in drier areas, such as most of Africa, may be limited in the future (Travis et al, 2006). The inadequate and unpredictable production of maize and the intense competition among maize-based industries in South Africa have resulted in expensive poultry diets (Mabelebele et al, 2015). Alternative energy feed sources such as sorghum can be used for broiler diets to improve their productivity and reduce costs.…”

The objective of this study was to determine the effects of low tannin sorghum as a maize replacement on the performance and bone morphometrics of Ross 308 broiler chickens. A total of 250 one-day-old broiler chickens were allotted to a complete randomized design with five treatments replicated five times. Birds were offered varying sorghum levels as maize replacement at 0% (control), 25%, 50%, 75% and 100%, formulated to be isonutritive and isoenergetic. The condensed tannin and total phenolic contents of the sorghum were analysed. Bodyweight and feed intake were measured weekly to calculate feed conversion ratio (FCR), and mortality was recorded as it occurred. Digestibility measurements were done when the chickens were between 15 and 21 days and between 35 and 42 days old. At ages 21 and 42 days, two chickens per pen were slaughtered to determine bone characteristics. A digital calliper was used to measure the length and diameter of the bones, and an electronic scale was used to determine the weight of the bones. Ash, calcium and phosphorus concentrations of the bones were determined. The Seedor and robusticity indices of the tibia were also calculated. The general linear model procedure of Statistical Analysis Software was used to analyse the data. At 1-21 days old bodyweight was higher for birds fed a level of 50% sorghum than those that were offered the control diet. Replacing maize with sorghum improved the metabolizable energy (ME) of broiler chickens aged 42 days. Bodyweight and FCR of birds fed diets with 50%, 75% and 100% sorghum were higher and better, respectively, than those on diets with 25% and 0% sorghum at 22-42 days old. Bone morphometries of chickens aged 1-21 days and 22-42 days were not affected by replacing maize with sorghum. Thus, maize can be replaced by a low tannin white sorghum without causing adverse effects on chickens.

Two experiments were conducted to determine the influence of sorghum variety and xylanase on performance of broiler chickens. In Experiment 1A, a total of 240 day-old Ross broiler chickens were assigned to a 2 (sex) × 3 (sorghum variety) × 2 (with or without xylanase) factorial arrangement in a completely randomized design with 20 chickens per treatment. Gross performance measurements were assessed at 7, 14, and 21 days of age. Carcass yield and visceral organ weights were measured at day 21. In Experiment 1B, a total of 108 female Ross 308 broiler chickens were randomly assigned to a 3 (sorghum variety) × 2 (with or without xylanase) factorial arrangement in a completely randomized design with 6 treatments replicated 6 times. On day 25, all birds were euthanazed by intravenous injection of sodium pentobarbitone and digesta contents from the distal ileum were collected to determine the nutrient digestibility. Broiler chickens offered sorghum variety Pan8816 supplemented with xylanase had higher feed intake, weight gain, and similar feed conversion ratio at 1 -7 days of age. Breast meat of broiler chickens was not affected by variety or xylanase. The small intestine was heavier in the Pan8625 and Pan8816 groups with xylanase than in the similar Pan8906 group. Enzyme inclusion increased the crude protein digestibility. When xylanase was included in all sorghum varieties, numerically, starch digestibility tended to improve. Sorghum variety affected the growth performance of broiler chickens. Furthermore, nutrient digestibility was affected by the differences in variety.
