  This investigation aimed to evaluate genetics of body conformation and feed efficiency characteristics in a selected line of Rhode Island Red chicken taking 100 numbers of single hatched out pedigreed chicks at Central Avian Research Institute (India). Data was analyzed by least squares analysis of variance. Least squares means of body weight, shank length, keel length, breast angle, body Weight Gain (WG), Feed Consumption (FC) and Feed Conversion Ratio (FCR) were estimated at various weeks of age. Sires of the chicks significantly (p<0.05) influenced the estimates of all the traits throughout the ages with a few exceptions. Chicks’ sex also affected (p<0.05) the estimates of all the traits excepting 4th week body conformation traits, FC at 6th week onwards and 6th week FCR only. Male birds demonstrated better estimates than females throughout the ages. The FC and 16th week FCR also varied (p<0.05) among different feeding groups. All the traits excluding FC were heritable at variable magnitude. The estimates of genetic and phenotypic correlations coefficients were positive in trends with high magnitude among the intra-week body conformation traits and least to high magnitude among various feed efficiency traits. Only WG and FCR were invariably negatively correlated with a range of low to high genetic correlation coefficients. These research-outcomes may serve as base information to the breeders and academicians.

  Pigmented Rice (PR) is one of the valuable food crops used in indigenous medicine. Thirteen PR varieties were collected from 3 climatic zones of South Sulawesi, Indonesia and analyzed for grain dimension, color and proximate composition. The PR were extracted using acidic ethanol and then measured their total phenolics, anthocyanins and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. Grain size determination showed that the length of the rice was in the range of 5.60-6.82. There was no significant different (p>0.05) in rice length and length/width ratio. The colorimetric results indicated that the darkest black glutinous rice had the lowest brightness parameter L* value which was negatively correlated with its total anthocyanin (r = -0.673) and phenolic (r = -0.559) contents. Proximate analysis results showed that all of PR varieties fulfilled the water content limit (≤14%). The total contents of ash, fat, protein, crude fiber and carbohydrate were in the range of 1.19-2.13, 1.06-3.05, 7.24-14.02, 0.66-0.99 and 71.29-77.14%, respectively. The anthocyanin and phenolic contents of black glutinous rice extracts were in the range of 94.70-202.46 mg Cy-3-glc/100 g db and 292.74-746.25 mg GAE/100 g db, respectively, which were higher than the black rice (66.08-113.83 mg Cy-3-glc/100 g db and 119.74-230.10 mg GAE /100 g db) and the red rice (0-12.85 mg Cy-3-glc/100 g db and 12.52-64.52 mg GAE/100 g db). Antioxidant activity was positively correlated with total phenolic (r = 0.886) and anthocyanin (r = 0.650) compounds. The data suggests the potency of black glutinous rice as a part of nutraceutical product formulation.

  Background and Objective: Arenga starch was extracted from the pith of sugar palm (Arenga pinnata), chemically modified by acetylation were produced acetylated arenga starches with different concentrations of acetic anhydride (4, 8, 12, 16% of starch basis). To evaluate the effect of acetylation on the structure and functional properties of chemical modified starches. Materials and Methods: The experimental research using material i.e., the arenga starch from the pith of palm sugar (Arenga pinnata), acetic anhydride 98%, NaOH, HCl, ethanol 96%, KOH 99.99%, H2SO4 96.1%, KBr, acetone and olive oil. Methods i.e., acetylation of arenga starch, determination of acetyl percentage and degree of substitution, fourier transform infrared (FTIR) spectra, X-ray diffraction, water and oil holding capacity, swelling power and solubility, crude fiber. Data were assessed by one-way analysis of variance and were carried out with Duncan’s multiple test (p<0.05). Results: The percentage of acetyl groups and degree of substitution increased with increasing in concentrations of acetic anhydride. Fourier transform infrared spectra of acetylated arenga starches additionally showed bands of varying intensity attributable to the acetyl groups introduced of the ester group in the sign to 1720.50-1728.22 cm–1. All starch granules were pattern of A-type crystallinity and relative crystallinity of acetylated arenga starches were lower than that native arenga starch. The water holding capacity, oil holding capacity, swelling power and fibre content of acetylated arenga starches increased but solubility decreased with the increasing in concentrations of acetic anhydride. Conclusion: Acetylated arenga starches were synthesized with acetic anhydride for use in food.
