Effect of Supplementation Purslane (Portulaca Oleracea) as a Source of Alpha-Linolenic Acid on Production Performance and Physical Quality of Egg of Laying Hens
The aim of the study was to evaluate the effects of inclusion plant source of n 3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the diets of layers on production performance and physical quality of eggs. A total of 125 Hy-Line Brown hens (38 weeks old) were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI) measured weekly and feed consumption ratio (FCR) was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment) were collected to analyse physical quality of eggs. The data were analyzed using Analysis of Variance (ANOVA). Differences between treatment means were further analyzed using Duncan\u27s New Multiple Range Test (DMRT). Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU). The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs
Detection of Pork Contamination in Fresh and Cooked Beef Using Genetic Marker Mitochondrial-dna Cytochrome B by Duplex-pcr
By mixing with pork, beef adulteration is frequently found in the traditional market that very disturbing Moeslem community in Indonesia. This study was conducted to detect pork contamination in fresh and cooked beef using genetic marker mitochondrial DNA cytochrome b (mt-DNA Cyt b) by duplex-PCR. A total of twelve samples was used in this study consisting six fresh meat samples and six cooked meat samples, respectively. Those beef and pork were bought from animal slaughterhouse and a supermarket in Surakarta. Cooked samples were prepared by boiling the meats in hot water at 100oC for 30 minutes. We designed pork contamination in beef in the level of 0, 1, 5, 10, 25%, respectively. The DNA genome was extracted and polymerase chain reaction (PCR) was performed using species specific primer to isolate mt-DNA Cyt b gene from the samples. The results showed that the DNA genome was successfully extracted from pork, beef, and contaminated meat samples. In addition, visualization of duplex-PCR on 1.5% agarose gel was able to detect pork contamination in both fresh and cooked beef up to very small proportion (1%). The existence of pork in beef was indicated with the presence of specific 398 bp DNA band. It can be concluded, duplex-PCR of mt-DNA Cyt b gene was very sensitive in detection of pork contamination in fresh and cooked beef
Pajanan Pestisida sebagai Faktor Risiko Hipotiroidisme pada Wanita Usia Subur di Daerah Pertanian
Pesticide exposure as a risk factor for hypothyroidism in women at childbearing age in agricultural areasBackground: Hypothyroidism in women at childbearing age (WCA) will cause reproduction disorder, i.e. infertility, spontaneous abortion, impaired growth and development of foetus, placental abruption, and preterm delivery. Pesticide exposure is suspected to cause hypothyroidism. The research objective is to prove that pesticide exposure is a risk factor for hypothyroidism among WCA in agricultural areas.Methods: Case-control studies were used as study designs. Study subjects were 44 WCA as cases and 45 WCA as controls. Pesticide exposure was measured by asking WCA\u27s involvement in agricultural activities using structured questionnaire and by checking their levels of cholinesterase. Hypothyroidism was determined based on the results of TSH, FT4, and T3 level. Confounding variables were also measured. These variables were age, body mass index (BMI), participation in hormonal contraception, liver function, urinaryiodine excretion, urinary thiocyanate level and blood lead level. Chi-square test, OR (95% CI), and multivariate logistic regression were implemented to test the hypothesis.Results: Pesticides exposure is a risk factor for hypothyroidism (crude-OR=3.04; 95% CI=1.20-7.81; nilai p=0.033 and adjusted OR=3.31, 95% CI=1.25 to 8.78, p=0.016). The higher the degree of exposure, the greater the risk of having hypothyroidism.Conclusion: Pesticides exposure is a risk factor for hypothyroidism among WCA in agricultural areas
Evaluasi Kualitas Organoleptik Mayonnaise Berbahan Dasar Kuning Telur yang Mendapatkan Suplementasi Tepung Purslane (Portulaca oleracea)
The aim of this research was to evaluate sensory quality of mayonnaise made with egg yolks produced from laying hens fed diets supplemented with purslane meal. The experimental design was a one way classification with five mayonnaise treatments. The treatments included mayonnaise with egg yolks supplemented with 0% (P0), 2% (P1), 4% (P2), 6% (P3), and 8% (P4) purslane meal. This study used 30 semi-trained panelists to evaluate sensory quality of mayonnaise using a 9-point hedonic scale. Data was analysed using the analysis of variance and if there was any significant difference among treatments, then the analysis was continued using Tukey’s test. The results showed that the use of egg yolks from laying hens fed diets supplemented with purslane meal up to a level of 8% did not significantly change color, texture, creamy, aroma, taste, taste and overall acceptance of mayonnaise. The average score of perception of sensory attributes was between 5 (neither like nor dislike) and 6 (slightly like). It can be concluded that mayonnaise made with egg yolks produced from brown laying hens fed diets supplemented with purslane meal up to a level of 8% did not negatively affect the sensory quality of mayonnaise
Entropy of chains placed on the square lattice
We obtain the entropy of flexible linear chains composed of M monomers placed
on the square lattice using a transfer matrix approach. An excluded volume
interaction is included by considering the chains to be self-and mutually
avoiding, and a fraction rho of the sites are occupied by monomers. We solve
the problem exactly on stripes of increasing width m and then extrapolate our
results to the two-dimensional limit to infinity using finite-size scaling. The
extrapolated results for several finite values of M and in the polymer limit M
to infinity for the cases where all lattice sites are occupied (rho=1) and for
the partially filled case rho<1 are compared with earlier results. These
results are exact for dimers (M=2) and full occupation (\rho=1) and derived
from series expansions, mean-field like approximations, and transfer matrix
calculations for some other cases. For small values of M, as well as for the
polymer limit M to infinity, rather precise estimates of the entropy are
obtained.Comment: 6 pages, 7 figure
