Abstract

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.

Abstract

This study was aimed to observe the requirements of non-phytate phosphorus (NPP) with phytase supplementation in starter phase broiler. A total number of 1000 broiler (500 males and 500 females) were divided into 5 dietary treatments for 21 days rearing period. The treatment diets (P1-P5) were basal diets with 0.67% Calcium (Ca) and 60 FTU phytase that combined with NPP at different levels, i.e.: 0.420% (P1); 0.345% (P2); 0.270% (P3); 0.195% (P4); 0.120% (P5). The basal diet was a corn-soybean based diet that contained 0.097% Ca and 0.124% Phosphorus (P). The data were subjected to a one-way ANOVA using complete randomized design. Response variables that observed in current study were: feed intake, nett gain, feed convertion ratio, average body weight, mortality and toe ash. Measurement of responses due to the reduction of NPP supplementation on average body weight and toe ash were then followed subsequently by generating equation for quadratic curve y = ax2+bx+c to determinate the NPP requirement. Determination of the maximum response was done through ymaks = -b/2a. Results showed that based on average body weight, estimation of NPP requirement with phytase supplementation were 0.317% for the 0-10 days; 0.314% for the 11-21 days; and 0.315% for the the 0-21 days rearing periods. Based on toe ash content, estimation of NPP requirement with phytase supplementation was 0.990% (toe) for the 21 days rearing period. This study was aimed to observe the requirements of non-phytate phosphorus (NPP) with phytase supplementation in starter phase broiler.

Abstract

The aim of this study was to determine the calcium requirements of broiler chickens in starter phase with the addition of phytase enzyme. This experiment used 1,200 broiler chickens (mixed sex) for 21 days rearing period in a closed house. The basal diets was corn and soybean meal which contained 0.097% Ca and 0.123% P-av. The treatments consisted of 6 diets treatment: P1 (basal diet with the addition of 0.42% non-phytate phosphorus (NPP), and then P2 to P6 were basal diet with the addition of 0.22% NPP and 1,000 FTU/kg phytase and the addition of calcium (Ca) at different levels: 0.82% (P2); 0.74% (P3); 0.66% (P4); 0.58% (P5) and 0.50% (P6). The growth performance, feed efficiency, and bone mineralization parameters were studied using Oneway ANOVA in a Completely Randomized Design. Duncan's new Multiple Ranges Test was used to separate means with significant differences. Results showed that 0.90% Ca supplementation without phytase and the reduction levels of Ca from 0.82% to 0.50% increased the amount of feed consumed by birds in all growth phases (P<0.05). The addition of phytase had beneficial effects on increasing body weight (P<0.05) and average of body weight gain (P<0.05), and decreased the value of FCR in 11 - 21 days and 1 - 21 days. The addition of phytase increased protein and energy consumption, followed by increased in the value of PER and  EER (P<0.05). When phytase was added in the diets, reduction levels of Ca in the diets up to 0.50% did not give any adverse effect on the tibia bone ash. It can be concluded that feeding with phytase can sustain growth performance, feed efficiency, and bone mineralization.

Abstract

This study investigated the effect of feeding atung (Parinarium glaberrimum Hassk.) seed meal on growth performance and haematology profile in broiler chickens. A total of 140 one-day-old male New Lohmann broiler chicks were randomly assigned to five treatment groups with four replicates and seven birds in each replicate pen. The dietary treatments consisted of feeding the same corn-soybean meal as the basal diet with atung seed powder inclusions at levels of 0, 0.5, 1.0, 2.0, and 4.0%, respectively. The data were statistically analyzed using One-way with five treatments and four replications and continued with Duncan's New Multiple Range Test for data with a significant difference. Results showed that feed intake increased (p<0.05) in broiler chickens fed diets with 0.5 and 1% atung seed powder. At the same time, the inclusion of atung seed powder had no effect on final body weight, weight gain, and FCR. Inclusion of 1 and 2% atung seed powder significantly increased leucocyte counts, as well as the PCV value trend increased with the inclusion of atung seed powder. It can be concluded that atung seed powder additives can be supplemented in broiler chickens feed at doses 1% by improving feed intake and some haematological profiles.

Abstract

This research aimed to investigate the characteristics of nanoencapsulated Citrus sinensis peel extract (NCSPE) applied in drinking water and its effect on broiler chickens' growth performance and jejunal histomorphology. The total of 192 Male Broiler chicken was distributed into six treatments with four replicates (Eight birds each replicate). The experimental  treatments were control diet and drinking water added with no treatment (T0; negative control), tetracycline 50 mg/l (T1; positive control), CSPE (Citrus sinensis peel extract) 1,5% (T2), CSPE 3% (T3), NCSPE 1,5% (T4), and NCSPE 3% (T5). The variables evaluated in this research were characteristics of NCSPE, growth performance. Data were analyzed using ANOVA in a completely randomized design. All data with a significant difference were then tested   again using the Duncan Test with a probability of less than 5%. Results showed  that the size of NEPM was 13,70 nm with a spherical shape and negative charges with zeta potentials of -13.37 mV. Supplementing 1,5% and 3% of NCSPE affects on feed intake, weight gain, and feed conversion ratio. It concluded that both 1,5% and 3% supplementation of NCSPE had a positive effect on growth performances.
