Abstract

The objectives of this experiment were to evaluate the effect of drought stress and trimming intervals on physiological responses of Indigofera zollingeriana. The experiment was arranged in a completely randomized design (CRD), 3x3 factorial and each treatment had four replications. The first factor consisted of 3 level of drought stress i.e: 100% field capacity (FC) (as a control), 50% FC, and 25% FC.  The second factor was comprised of 3 trimming intervals, those were at 60, 90 and 120 days. The observed variables were leaf water potential, relative water content, proline, and water soluble carbohydrate (WSC) concentrations. Data were analyzed by ANOVA and differences between treatments were tested by LSD. The results showed that there were no interaction (P<0,05) between drought stress and trimming interval on all observed variables. Drought stress treatment significantly (P<0,05) decreased leaf water potensial and relative water content, whereas proline, and water soluble carbohydrate (WSC) contents increased. Trimming interval significantly (P < 0.05) on leaf water potensial, and water soluble carbohydrate, whereas the relative water content and proline content were not significantly. Key Words: Indigofera zollingeriana, Drought stress, Trimming interval, Physiologycal response

Abstract

This study was aimed to determine the right level of vitamin C in extracted pineapple rind to prevent heat stress effects so it does not interfere with the performance of broiler chickens. This study was done in a series of field experiments. Experiments in the field/cage was biological test of the effect of vitamin C from pineapple rind on production responses (percentage of body weight gain and carcass) and physiological responses (thyroxine hormone levels) in broiler chicken aged 3 weeks as many as 360 of Strain Arbor acress. The basic design used was CRD 3 x 4 factorial models and 3 replications with 10 chickens for each box, as factor 1: Room temperature (21 : 27 and 33ºC), and factor II: level of vitamin C in the pineapple rind (0:500:1000 and 1500 ppm). The data obtained were statistically analyzed using SAS program package, and if it showed any significant effect then followed by Duncans test/DMRT. Variables measured were body weight gain, carcass percentage and levels of thyroxine hormone of broiler. Results showed that addition of pineapple rind containing 500 ppm vitamin C in the drinking water reduced heat stress in chicken that were kept at temperature of 27ºC, while at 33ºC needed 1000 ppm vitamin C. Both treatments increase level of thyroxine hormone, produce weight gain equal to control, more over, there was no effect on the percentage of carcasses. Key Words: Ananas comosus L. Merr, Vitamin C, Tyrosine, Anti-Stress, Broiler Chickens
