Effect Of Using Simple Technique Methods To Reduce Sorghum Phytate On Performance Of Broilers And Layers

Abstract

Three experiments were conducted to investigate the effect of reducingphytic acid from sorghum bicolor (the main dish of poultry in Sudan) on performance of broilers and layers by using simple technique methods.Firstly, an Experiment was conducted to reduce phytic acid from Sudanese Sorghum bicolor local name FeteritaGadarif (F.G) using a simple technique methods. An approximate analyses was done to determine the nutrition value of the grains before and after processing methods ,and to measure the change of nutrient content after processing treatments .The treatments of processing were divided into five methods of process in addition of control (unprocessed cereal) such as dehulling, germination, soaking, vitamin c addition and storing methods respectively to reduce phytic acid content of the grains. The treatments shown significant decrease (p>0.05) in phytic acid contents of the processed sorghum as compared with unprocessed one(control).The highest los of phytate registered in germination method (98%)fallow by vitamin C treatment(86.2%),soaking(78.6%),storing (59.6) and dehulling method respectively. There were a significant increase (p>0.05) in metabolic energy ,Ca , and Fe of cereal nutrients content after processing operation obtained by method of germination and some slight increase of protein content of all processed grains The second experiment was divided into Towperiods ,starter and finishing period.300one day old unsexed broilers (HybroB) used. Six experiment diets were formulated with different level of processed sorghum(F.G),with 5replicates in complete randomize design .Feed intake, body weight were weekly recorded, then weight gain and feed conversion ratio were calculated, mortality was alsorecorded,25 birds from each treatment were randomly selected, weighted and slaughtered for deterring carcass dressing percentage. Internal organs weighted and serum analyzed Result obtain showed that feeding broilers processed grain(F.G),significantly affected(p>0.05)feed intake, body weight gain, dressing percentage, live and hot weight. Treatments had a significant increase effect (p>0.05)on whole blood serum contents ,high level of ,glucose, andcalciumwere observed in birds fed on processed grains .There was a significant decrease(p>0.5) in serum cholesterol obtained by birds fed on processed grains. Treatments had a significant increase ( p>0.01)in level of tibia ash observed by birds fed on processed grains as compared with control . The third experiment was investigated the effect of processing sorghum on performance of layers Atonal of (90)chicken (17 week old) were used randomly into 18 pens in group of (5 birds per pen and 3pens per treatment). Feed intake and egg weight were weekly recorded, then feed utilization was calculated, mortality was also recorded. The five processing methods had a significant positive effect on egg production, feed utilization, egg shell weight, egg thickness, yolk high, hug unitand slight increase in egg weight and body weight. Treatments had a significant increase (p>0.05) on egg cholesterol content obtained by birds fed processed seed as compared with control .There was a significant increase in ash, and calcium content in Toe and egg shell observed in laying hens fed on processed sorghum
