“…However, bodyweight and FCR of birds given 50%, 75% and 100% sorghum were higher and better (P <0.05), respectively, than those on 25% and 0%. Contrary to these findings, Tandiang et al (2014) reported that FCR and bodyweight were lower and higher for broiler chickens on maize and 100 % low tannin sorghum-based diets, respectively.

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.

“…Recent studies demonstrate the possibility to use sorghum in broiler diets even in the initial stage, at levels up to 100% of corn, without restrictions in later stages (FAGUNDES et al, 2017;PIMENTEL et al, 2007;ROCHA et al, 2008;TORRES et al, 2013). However, Tandiang et al (2014) and Batonon-Alavo et al (2015) observed that high levels of substitution may decrease the performance of broilers, which was not observed in the present experiment. Performance is directly affected by nutrient digestibility, mainly dry matter digestibility, which was not reported in the digestion trial.…”

The aim of this study was to evaluate the effects of sorghums grown with different organic fertilizers on the chemical composition, energy values, and nutrient metabolizability coefficients, as well as their use for feeding slow-growing broilers. Two trials were performed. In the first experiment, 200 21-dayold broilers were distributed in a completely randomized design (CRD), with five treatments and four replicates of 10 birds per experimental unit. The treatments consisted of a control diet and four test diets (sorghum fertilized with crotalaria, sorghum fertilized with millet, sorghum fertilized with humus, and sorghum without fertilization), including sorghum at 30% in the control diet. The apparent metabolizable energy (AME), apparent metabolizable energy corrected for nitrogen balance (AME n ), metabolizability coefficients of dry matter, crude protein, and gross energy were evaluated. In trial 2, 200 1-day-old chicks were used in a CRD with five treatments (T1 -control diet with commercial corn, T2 -sorghum fertilized with crotalaria, T3 -sorghum fertilized with millet, T4 -sorghum fertilized with humus, and T5 -sorghum without fertilization) and four replicates of 10 birds per experimental unit. Weight gain, feed intake, feed conversion, and final weight at 28 days were evaluated. The values of AME and AME n of sorghums fertilized with crotalaria, millet, humus, and sorghum without fertilization were 2894 Kcal kg -1 and 2881 Kcal kg -1 ; 2736 Kcal kg -1 and 2675 Kcal kg -1 ; 2727 Kcal kg -1 and 2694 Kcal kg -1 ; and 2994 Kcal kg -1 and 2959 Kcal kg -1 , respectively. The metabolizable coefficients of dry matter, crude protein, and gross energy were 76.04%, 42.01%, and 75.25% for sorghum fertilized with crotalaria; 77.50%, 50.77%, and 75.95% for sorghum fertilized with millet; 77.62%, 46.39%, and 75.54% for sorghum fertilized with humus; and 75.83%, 39.53%, and 74.71% for sorghum cultivated without fertilization, respectively. The dietary use of sorghum cultivated with different fertilizers did not affect (P>0.05) weight gain, feed intake, feed conversion, and final weight. Green manures with crotalaria, millet, and humus (bovine manure) are alternatives that can be used on sorghum crops because they resulted in grains with adequate nutritional composition, energy values, and metabolizable coefficients for slowgrowing broilers from 1 to 28 days of age. Key words: Alternative poultry farming. Productive performance. Metabolizable energy.

“…In a study conducted by Tandiang et al (2014), replacing corn with conventional sorghum at the level of 333.3 or 500 g/kg of diet impaired broilers' BWG and feed efficiency. This effect was attributed to the negative effects of sorghum tannins.…”

This study was conducted to investigate the potential for replacing corn with oak acorn (OA), a tanninrich feedstuff, and the possible role of polyethylene glycol (PEG) in reducing detrimental effects of OA on broilers. A 3 × 2 factorial arrangement of treatments was used with three levels of OA (0, 150, and 200 g/kg diet), with and without 10 g/kg PEG. A total of 528 one-day-old male and female Cobb 500 broiler chicks were randomly assigned to one of six experimental treatments, with four replicates of 22 birds each. OA was included in the starter (days 1-21) and finisher (days 22-42) diets as a replacement for corn, without changing the dietary levels of other ingredients. The results indicated that dietary inclusion of OA, without PEG, significantly reduced bodyweight gain (BWG) overall (days 1-42) and resulted in worse finisher and overall feed conversion ratios (FCR). PEG had no significant effect on the performance of birds fed diets without OA, but improved overall the BWG of birds receiving 150 and 200 g/kg OA as well as finisher and overall the FCR of birds given 150 g/kg OA. Liver and pancreas weights were not significantly influenced by OA level, PEG or their interaction. Feeding with 200 g/kg OA had deleterious effects on some tibia traits. In conclusion, a significant interaction between OA level and PEG indicates that PEG has the potential to reduce the adverse effects of OA, leading to improved performance. Thus, up to 150 g/kg OA could be included in PEG-supplemented diets, without adverse effects on performance or the tibia traits of broilers. ______________________________________________________________________________________
