Abstract

An experiment was conducted to evaluate the effect of the inclusion of different levels of shrimp waste meal fermented with Aspergillus niger (LUF) in diets on growth performance and digestive organ weight of broilers. A total of 75 d-old chicks were randomly allocated to 5 (five) treatments in 3 replication pens of 5 birds each. Treatments consisted of LUF inclusion of 0 (control), and 5, 7.5, 10 and 12,5% (P0, P1, P2, P3 and P4) in the diets. Birds were raised under standard condition and provided with feed and water ad-libitum. Feed and birds were weighed weekly up to 35 days to determine body weight, feed intake and feed conversion. At the end of experimental period, the birds were slaughatered and dressed up to determine carcass percentage and digestive organ weight. There was a significant negative linear response in body weight, feed consumption and feed conversion with increase of LUF more than 7.5% in the diets until 35 days of age, but % carcass was almost the same for all treatment. There was no significant response in digestive organ weight with increasing levels of LUF. The present result indicated that LUF could be considered as a potential feed ingredient as protein source of broiler but its inclusion should be limited until 7.5% of the diet to maintain growth performance and digestive organ weight.

Abstract

Egg containing long chain unsaturated fatty acids is a functional food, because it is highly nutritious and could prevent diseases, (omega 3 and 6) such as coronary heart attack. The research was aimed to measure the change of egg cholesterol content  during proceesing: frying, oiless frying and boiling and their influence to the blood plasma cholesterol of normal and hypercholesterolemia rat. Seven treatments of egg yolk were frying at 170°C for 3 min (welldone = GM), and 1min (half medium fried = GSM) using deep fryer , oilless frying at 70°C for10 min (fried = TM), and 6 min (half fried = TSM) using Teflon pan, and boiling at 100°C for 10’ (boiled = RM) dan 4 min (half boiled = RSM) using pan provided with thermoregulator and a fresh omega egg as a control. The Completely randomized design was apllied for 4 weeks research period. The data from different treatments were analyzed by Orthogonal Contrast. Fifty 2 months old male rats Rattus norvegicus L. separated in 2 groups; normal and hypercholesterolemia (blood cholesterol > 200 mg dl-1). The rats were placed in individual cage, fed 15 g h-1 day-1 and water drinking ad libitum. The ration was composed of 90% basal commercial feed BR II and 10% egg yolk was given to each animal at 20% of live weight. Factorial 2 x 7 of completely randomized design was applied. The data were analyzed by ANOVA and Duncan’s Multiple Range Test. Processsing method of egg affected to cholesterol content of egg, The lowest and the highest cholesterol contents were observed in TSM (0.30 g/100g) and GM (0.37 g/100g), respectively. Biological test using Rattus norvegicus L rat showed that either fresh and processed long chain fatty acid egg decreased plasma cholesterol.  The highest and the lowest decreases of cholesterol content were found in the group consumed RSM (8.64%) and GM (1.77%) for normal rat; and control (46.3%) followed by RSM (44.53%) and GM (24.86%), respectively.  To maintain normal cholesterol and decrease cholesterol content of cholesterolemian, the omega egg should be consumed in fresh or half boiled egg.

Abstract

Research has been conducted to determine the effectiveness of antioxidant supplementation of vitamin E and C in the feed to meat quality of the Muscovy duck meat stored at room temperature, refrigerator and freezer.  Eighty-four Muscovy duck tail males aged 9 weeks maintained for 5 weeks and allocated into 7 treatments with 4 replications and each replication consisted of Muscovy duck 3 heads. Completely Randomized Design was applied, in the which treatments were vitamin E and vitamin C supplementation to the basal feed containing 21% protein and 3100 kcal / kg administered metabolic energy into seven groups namely E0C0: basal feed without Vit E and Vit C, E400: basal feed plus 400 IU of vitamin E, E600: basal feed plus 600 IU of vitamin E, C400: basal feed plus 400 mg / kg feed vitamin C, C600: basal feed plus 600 mg / kg feed as much vitamin C, E200C200: basal feed plus 200 IU vitamin E and 200 mg / kg feed vitamin C, and E300C300: basal feed plus 300 IU of vitamin E and 300 mg / kg feed of vitamin C. The parameters measured were the color of meat that includes the value of L * (lightness), a * (Redness) and b * (yellowness), tenderness and cooking looses.  The data obtained and the analysis of variance followed honestly significant difference test.Muscovy duck meat that vitamin E-supplemented feed brightness levels did not differ (P> 0.05) with non-supplemented,  otherwise Muscovy duck meat that feed supplemented vitamin C or a combination of vitamin E and C levels of brightness up to 3 days either at room temperature or stored the refrigerator is still high.  Supplementation of vitamin E and C was highly significant (P <0.01) against redness (a*) meat stored in different storage means. Muscovy duck meat that feed not supplemented vitamin E and C redness (a*) did not differ (P> 0.05) between the age of 0 hours with that stored in the refrigerator or freezer. B * value of Muscovy duck meat that feed not given vitamin E and C as well as different combinations (P <0.05) with Muscovy duck meat that feed supplemented with vitamin C or a combination of vitamins E and C. The Muscovy duck meat that feed supplemented vitamin E, C or a combination of vitamins E and C if stored at room temperature or refrigerator up to 3 days the value of L* and a* is still high, but the b * low.

Abstract

This research was conducted to evaluate the effect of turmeric water extract, garlic and combinations of turmeric and garlic as feed additives in broiler diets on the physical and sensory quality of broiler meat. During the study, the chicken were given 5 feeding treatments, i.e. R0 (basal ration without phytobiotic and antibiotics) , R1 (basal diet + 0.015% zinc bacitracin + 2.485% filler), R2 (basal ration + 2.50% TE), R4  (basal ration + 2.00% GE + 0.50% filler), and R5 (basal ration + 2.50% TGE). The base diet was composed of: yellow corn, meat and bone meal, poultry meat meal, soybean meal, oil, mineral mix, calcium carbonate, dicalcium phosphate, salt, L-lysine-HCl, and DL-methionine. Variables observed were physical quality (pH, water holding capacity, cooking lose, and tenderness) and sensory quality. Data regarding physical quality were statistically analyzed by one-way ANOVA followed by the orthogonal contrast for significant results, and data of sensory quality by non-parametric methods such as the Hedonic Kruskal-Wallis test. The results showed that the physical quality of meat had no effect (P>0.05), except the significant water holding capacity (P<0.05) which was lower with phytobiotic extract supplementation. All sensory test parameters in fresh and cooked meat had no effect (P>0.05) following phytobiotic extract supplementation, except for the color and acceptability (P <0.05) in fresh broiler meat. The conclusion of the research was that 2.5% TE, 2.0% GE and 2.5% TGE is capable of acting as a feed additive to increase the physical and sensory quality of broiler meat.

Abstract

The Objective of the study was to identify microhabitat characteristics in natural nesting ground as a basic form of egg hatching of maleo birds for ex-situ habitat in Lore Lindu National Park. Survey methods and experimental design were applied in this study using Saluki Nesting Ground as a habitat model. In a natural habitat, variables observed were microclimate condition (temperature and humidity, depth and diameter of holes) while in an artificial habitat where four different forms of eggs hatching (in-situ, ex-situ, incubator by means of media rack and sand) were applied temperature, humidity, hatching quality, incubation time, hatching weigh, and mortality were determined. Data analysis applied was descriptive analysis and multivariate test using SPSS computer program. Results of the study showed that in the natural nesting ground the temperature ranged from 30 to 35 oC with an average temperature of 33.03oC, and the humidity from 60.20 to 71.10% with an average humidity of 68.55%. The hole diameter ranged from 28-63 cm with an average hole diameter of 41.64 cm and the hole depth from 51-87cm with an average hole depth of 63.29 cm. The application of hatching method was resulted in the in-situ temperature and humidity of 32.90 oC and 68.41%, respectively, and the ex-situ of 31.68 oC and 67.52%, respectively, rack incubator of 33.99 oC and 70.06%, respectively, and sand incubator of 33.78 oC and 71.02%, respectively. The longest incubation time was found in the ex-situ semi natural hatchery which was 78.40 days, followed by the in-situ habitat 63.48 days, rack incubator 59.40 days, and sand incubator 59.33 days. The best hatching quality was found in the rack incubator, but the mortality rate was highest. The application of incubator for egg hatching of maleo birds could reduce the incubation time length and increase the hatching quality
