Effects of Layered Clothing on the Post-mortem Decomposition of Rat Carcasses on Grass Bushes and Dead Leaves (Kesan Pakaian Berlapis Terhadap Penguraian Postmortem Bangkai Tikus di atas Dedaun Rumput yang Telah Mati) / Jurnal Sains Kesihatan Malaysia

@#A post-mortem decomposition is defined by the evaluation of the physical and chemical changes of a cadaver or a carcass in order to estimate the cause of death and the time of death. The purpose of this study is not to replicate a real crime scene but to enhance knowledge of the effects of clothing in a decomposition process, mainly, the effects of layered cotton clothing on the post-mortem decomposition of adult female rat carcasses. Fifteen rats were divided into three groups: control, one-layered and two-layered clothed. The control subjects were unclothed and used to compare the post-mortem changes with the clothed subjects, one-layered and two-layered rat carcasses. All subjects were placed outdoor, 2.5 meters away from each other on grass bushes and dead leaves. Ambient temperature and humidity were recorded to observe if it associates with the post-mortem changes of the rats. Insect activity on each subject was observed. Post-mortem changes were measured using the Total Body Score system. The results showed that the control group underwent a faster decomposition compared to the clothed groups. The different layers of clothing did not show a vast difference in post-mortem changes. The ambient temperature of 28°C influences the post-mortem decomposition. The decomposition was rapid under the dominance of maggots compared to ants as ant colonies delayed the decomposition process. The study gave the knowledge of the effect of clothing in decomposition of female rats in forensic science.

Porcas lactantes alimentadas com dietas contendo silagem de grãos úmidos de milho e ácidos orgânicos / Lactating sows fed with high moisture corn diets and organic acids

Um experimento foi realizado para avaliar o desempenho de porcas lactantes e suas leitegadas alimentadas com dietas contendo silagem de grãos úmidos de milho com ou sem ácidos orgânicos. Foram utilizadas 15 porcas híbridas em um delineamento de blocos ao acaso com três tratamentos (dieta controle, dieta com adição de 0,5% de ácido benzóico e dieta com adição de 0,5% de ácido fumárico) com cinco repetições cada. As dietas elaboradas com silagem de grãos úmidos de milho com ácido benzóico ou ácido fumárico não alteraram (P>0,05) a espessura de toucinho e o consumo médio diário de ração. O ganho médio diário (0,22kg) e o peso vivo médio ao desmame (6,2kg) dos leitões não diferiram (P>0,05) entre os tratamentos. A adição dos ácidos fumárico e benzóico nas dietas elaboradas com silagem de grãos úmidos de milho não altera os desempenhos de porcas lactantes e de suas leitegadas.

An experiment was carried out to evaluate the performance of lactating sows and their piglets fed with high moisture corn diets with or without organic acids. Fifteen sows were used in a randomized complete block with three treatments (control diet; control diet with 0.5% of benzoic acid; control diet with 0.5% of fumaric acid) with five replications each. The diets were elaborated within a 24h period. Diets elaborated with high moisture corn with benzoic or fumaric acids did not modify (P>0.05) the backfat thickness and the average daily feed intake. The average daily weight gain (0.22kg) and average weaning live weight (6.2kg) of piglets were not influenced (P>0.05) between treatments. The addition of organic acids in diets containing high moisture corn does not alter the performance of lactating sows and piglets.
