Abstract

Phytate is commonly high in cereals grain. This compound can be extracted with acid solution. The purpose of this study is to extract phytic acid from pollard using acetic acid at the concentration of 0.1, 0.5, 1, and 5%. Pollard was fractionated using vibrator ball mill to evaluate the distribution of phytic acid in the particle of pollard. One percent of acetic acid was used to extract phytic acid from pollard at ratio of 1:1; 1:1.5; 1:2; and 1:3. The fraction having particle size of 16, 30 and 50 mesh had similar phytic acid content. The results indicated that phytic acid content of these fractions was higher than that of 100 and 400 mesh fractions. Whole pollard had higher phytic acid content than its fractions. Phytic acid in pollard can be extracted by 1% acetic acid solution. Extraction of phytic acid from pollard using 1% acetic acid solution at ratio of 1:3 produced 23.83 g/kg. Key words: extraction, phytic acid, pollard, acetic acid

Abstract

Phytate is commonly found in high concentration in rice bran. This compound can bind multivalency ions. The purpose of this study was to know the effect of rice bran in native chicken diet on Cd absorption. Twenty four native male chicks aged 3 months were randomly divided into six groups of treatments. The average weight of chick used in this experiment was 422.08 ± 39 g. The dietary treatments were 0% (R0), 10% (R1), 20% (R2), 30% (R3), 40% (R4), and 50% (R5) of rice bran in the ration given for 8 weeks. Drinking water containing 100 ppm Cd was given ad libitum. The results indicated that those treatments had no significant effect on Cd absorption, Cd concentration in feces, kidney, liver and weight of kidney and liver. Average of Cd in kidney and liver were 284.24 and 117.53 ppm respectively. It was concluded that rice bran in the native chick diet did not reduce Cd absorption. The utilization of rice bran and Cd pollution for long term period and in high concentration in the diet gave negative effect on native chicken performance. Key words: rice bran, phytate, cadmium, native chicken

Abstract

This study aims to evaluate the effects of probiotic administration on the performance of laying hens. The research method involves two groups of laying hens kept under the same conditions, with one group receiving probiotic supplementation and the control group receiving standard feed. Parameters observed include egg production rate, egg weight, mortality rate, and overall health. Statistical analysis (t-test, p < 0.05) indicates significant differences between groups. The results suggest probiotics enhance productivity and health, with economic benefits for farmers.
