Abstract

The purpose this study was evaluate the utilization of nanoparticles silver (AgNPs) on performance and ammonia concentration in broiler excreta. This study used a factorial completely randomized design with 3x2 treatments and 4 replicates. First factor (AgNPs at drinking water) was P1 = 0 ppm, P2 = 2 ppm, and P3 = 3 ppm and the second factor Q (AgNPs by misty) was Q1 = 0 ppm and Q2 = 4 ppm. The variables measured were excreta ammonia content, feed consumption, body weight gain, feed conversion ratio, mortality, temperature and relative humidity. The results showed that there was no interaction between AgNPs in drinking water and AgNPs in its mist form on ammonia content. AgNPs 4 ppm by misty also affected reduce FCR and body weight gain at week 3, also increased FCR at fourth week. AgNPs in drinking water affected (P < 0.05) amonia content. AgNPs 2 ppm in drinking water reduce until 11% amonia content. AgNPs by misty also reduced (P< 0.05) amonia content. AgNPs 0 ppm and 4 ppm by misty not created comfort temperature and relative humidity for broiler chicks. It is concluded that the addition of silver nanoparticles reduce excreta ammonia levels of broiler chickens. Key words: amonia, humidity, misty, NanoSilver Particles (AgNPs), relative temperature

Abstract

This experiment was design to evaluate the effects of supplementation of Zn and Cu in inorganic or organic form on broiler’s percentage of giblets and abdominal fat of 35-day-old broiler chickens. The experiment used a completely randomized design with two treatments, 17 replicates and 32 birds per pen (816 female and 272 male). The treatments based on the type of mineral i.e. inorganic (T1) and organic (T2). The types of mineral did not affected the weight and percentage of weight of bursa fabricius, lymph, heart, bile gland, kidney, and abdominal fat. The types of mineral did not affected the weight of thymus, liver, proventriculus, pancreas, and gizzard, but were affected their percentage of weight (p<0.05). The types of mineral were affected the length and percentage of weight of duodenum, jejunum,and ileum (p<0.05) . The types of mineral were affected the length of secca, but did not affected its percentage of weight (p<0.05). The types of mineral did not affected the length of colon, but were affected its percentage of weight (p<0.05). The supplementation of mineral Cu and Zn in organic form has better absorption of nutrient and positive effect to health of chickens in stress due to heat stress. Key words: broiler, copper, inorganik mineral, organik mineral, zinc

Abstract

The purpose of this study was to evaluate the effect of supplementation of Garcinia xanthochymus extract in drinking water on the quail meat and eggs quality (fat content, protein content) and malondialdehyde (MDA) on egg yolk. This study used female quails (132 tails) aged 42 days, which were kept for 6 weeks, and then divided into four groups treatments of drinking water, and 3 replications each treatment. The method used was a Completely Randomized Design (RAL) with P0 (control), P1 (pH 4), P2 (pH 3), P3 (pH 2). The variables observed were moisture content, crude fat content and crude protein content in quail meat and eggs but MDA only on yolk eggs. The results showed a significantly decreased (p<0.05) effect of Garcinia xanthochymus extract supplementation in drinking water on MDA levels of yolk quail eggs. However it had no significant effect on moisture content, crude fat content, and crude protein content in yolk quail eggs . The treatments had significantly increased crude protein in meat. It was concluded that giving extract of Garcinia Xanthochymus extract (kandis acid) at pH 2 in drinking water decreased the MDA content of quail egg yolks. Key words: antioxidant, Garcinia Xanthochymus, chemical compound of meat and egg, egg yolk MDA
