Abstract

Forty laying hens Hysex Brown consisting of 2 age groups (27 and 77 weeks of age) were used inthe study to elucidate the hypocholesterolemic effect of garlic powder on egg production, serum and eggcholesterol. They were caged individually and fed diet containing 0 (control), 1, 2, and 4% oven driedgarlic powder for 4 periods of 4 weeks. The old hens consumed more food compared to those of theyoung one, while water consumption was in the reverse condition. The egg production indicated by theyoung hens fed dietary 1 and 2% garlic powder was significantly higher than those fed control diet.However, the old hens produced heavier eggs than those of the young hens, particularly when 1% garlicpowder was supplemented. There was a closed relationship between serum and egg cholesterol, whichreduced gradually with longer time the hens fed dietary garlic. The results clearly demonstrated that thelaying hens fed dietary garlic powder up to 4% produced egg containing lower cholesterol (-34%)compared to those fed control diet; The hypocholesterolemic effect of garlic powder is apparently higherin the old hen compared to that in the young hen.

Abstract

Four does (goat, G) and four ewes (sheep, S) of Jeneponto were fed chaffed rice straw hay (3.7%crude protein, 63.5% cell wall constituents, 44.5% acid detergent fiber and 6.2% acid detergent lignin,all based on dry matter). The intakes and digestibility of the diet by G and S were compared. Bothspecies consumed the same level of the diet. G digested dry matter, organic matter, crude protein, crudefiber, and lignin of the diet to a significant higher extent than did by S. The superiority of G over S indigesting the diet was attributable with longer retention time of ruminal fluid and particulate matters inthe rumen and the entire gut, which then resulted in higher proportion of small size particles (<1 mmsieve), higher proportions of propionic, butyric, valeric and isovaleric acid concentrations produced inthe rumen. Additionally for further studies, there were some possibilities of G having a better chewingactivity (duration and intensity), and ability to maintain higher rumen ammonia levels by a greater urearecycle to the rumen, particularly through salivation.

Abstract

The study was conducted to investigate the effect of prebiotic, probiotic, and synbiotic supplementation through drinking water on broiler performance and small intestine morphology. A total of 100 day-old broiler chicks (Ross) were randomly allocated into 4 treatments with 5 replicates, with 5 broilers in each experimental unit for 35 days. The drinking water treatments were P0: Water (Control); P1: Water + Prebiotic (5 g/L); P2: Water + Probiotic (3 g/L); P3: Water + Synbiotic (Probiotic 3 g/L + prebiotic 5 g/L). Commercial feed consisting of the three rearing phases was used during the study, and drinking water was provided ad libitum. Parameters measured were water and feed consumption, body weight gain, feed conversion, performance index, small intestine morphometry, which is measured by the length/weight ratio, and Histo-morphometry of the small intestine of individual segments, duodenum, jejunum, and ileum at the end of the experiment on 3 chicken samples (lightest, medium, heavy) from each treatment. The results showed that prebiotic, probiotic, and synbiotic supplementation through drinking water significantly (P<0.05) affected drinking water and feed consumption, body weight gain, feed conversion, length/weight ratio, and histo-morphology of the small intestine. Overall, it can be concluded that synbiotic supplementation demonstrated a synergistic effect between prebiotics and probiotics, outperforming prebiotic and probiotic supplementation separately in terms of performance, small intestine ratio, and small intestine histomorphology. Synbiotics also significantly showed a trend towards feed use efficiency, as seen in feed conversion.
