This study aimed to evaluate the effects of phytase and tannase addition in broiler diets on the growth performance and meat quality of broilers fed sorghum-based diets. Twelve experimental diets were formulated at three sorghum levels (0, 50, and 100%)…

The apparent and true metabolizable energy concentrations of 22 cultivars of sorghum grains, differing in their tannic ac id content, were determined by feeding samples of the different varieties to adult roosters. A highly significant negative correlation was found to…
Three groups of nine steers each were fed fattening diets, containing either non bird-resistant (NBR), paraformaldehyde-treated bird-resistant (PBR) or bird-resistant (BR) sorghum grain as the energy source, for 105 days. The BR group performed consistently worse than both the NBR…
Two experiments were conducted, (1) to determine the effect of the polyphenol content of sorghum on nitrogen and energy digestibility and (2)to compare a high polyphenol content class KF sorghum cultivar (BPS)and a low polyphenol content class KM cultivar (NS)…
An experiment was conducted to (i) determine the effect of heat treatment and thermal ammoniation on dry-matter digestibility and true metabolizable energy content of high-tannin grain sorghum in a digestion trial with roosters and (ii) to determine the relative nutritive…
Two experiments were conducted to (i) determine the effect of thermal ammoniation (NH3BPS) and heat treatment (HBPS) of birdproof sorghum (BPS) on energy and N metabolism, measured with intact and ileo-rectal anastomosed pigs and (ii) to evaluate NH3BPS and untreated…
This experiment was conducted to determine apparent and true amino acid digestibilities of untreated (BPS), heat-treated (HBPS) and thermal-ammoniated (NH3BPS) high-tannin sorghum with pigs both intact and with an ileo-rectal anastomosis (IRA). The mean endogenous protein secretion for the surgically…
A comparison of broiler performances on milled and unmilled sorghum-based diets: This study was undertaken to determine whether it is essential to mill sorghum before it is included in broiler diets. Remarkable savings can be achieved if unmilled sorghum could…
Bana grass (Pennisetum purpureum x P. amerieanum) was compared with kikuyu (P. clandestinum) and forage sorghum (Sorghum bicolor) with respect to quality of samples ;elected by four oesophageally fistulated steers. Hand-cut samples of the three forages were also compared…
The effect of feeding sorghum condensed tannins on intestinal growth, function and histology was investigated in an 8-week broiler growth trial. Four sorghum varieties of different proanthocyanidins (PA) content; DC75 (DC - 2.48 A550nm/g DM) Chirimaugute (CH - 1.68 A550nm/g…
A study was conducted to investigate the effects of wood ash treatment on the nutritional value of high tannin sorghum. High tannin sorghum was either soaked in wood ash slurry and then germinated for four days or soaked in wood…
The experiment was conducted (i) to compare the chemical and physical composition of grain sorghum produced at different locations, (ii) to compare the digestible energy (DE) content of different grain sorghum cultivars produced at different locations, and (iii) to evaluate…
