Abstract

The purpose of the research was to  obtain  information regarding the performance of indigenous chicken  under   intensive  rearing. The  performance criteria were the increasing body abdominal weight, fat, rectal temperature, and the indigenous chicken’s mortality within the 5-week starter phase treatment. Research was conducted using 108 Day Old Chick (DOC). Data variance was analysed  based  on  the  split  plot  design  (3  types  of cage  litter  materials,  5 weeks  of data collection,  and   4   replications)   for   weight   gain   and   abdominal   fat parameters,   and completely  randomized  design  in  time  for rectal temperature. The result indicated a significant  effect  of  different  litter  materials  towards  weight  gain  (P  <0.01), the  highest body weight  was found on  chicken treated with rice straw litter; there was  no effect  of litter material on abdominal fat percentage; there was a significant effect (P < 0.01) of age towards rectal temperature; and there were no  interactions  between litter material with age,  on body weight  gain,  abdominal  fat,  and  rectal  temperature.  Chickens  under intensive  rearing  in rice straw floored cages were proven to have a mortality rate reduced by 3.7% in the starter phase.doi: http://dx.doi.org/10.12777/ijse.4.2.2013.52-56 [How to cite this article: Sulistyoningsih, M., Sunarti, D., Suprijatna, E., & Isroli, I.

Abstract

The objectives of this study were evaluate the dietary turmeric powder and swangi fish meal onsize of muscle fiber diameter and fat tissue score of major pectorales and semimembranosus of quailmeat. Research was conducted based on 2x3 of factorial completely randomized design, in which thefirst factor was 2 types of diet, i.e. RA : standard diet; RB : 85% standard diet + 15% swangi fish meal,and the second factor was 3 levels of period time of turmeric powder addition, i.e. P0 : without turmericpowder; P1 : turmeric powder 54 mg/quail/day was given since quail age 210 days old; P2 : turmericpowder 54 mg/quail/day was given since quail age 14 days old. Difference of means between treatmentgroups were analyzed by Duncan’s Multiple Range Test in 95% significance level. The results showedthat combined treatment of tumeric powder with RA (P0 : 2.33 μm; P1 : 3.06 μm; P2 : 2.98 μm) and RB(P0 : 2.22 μm; P1 : 3.12 μm; P2 : 2.92 μm) increased (P<0.05) muscle fiber diameter on majorpectorales significantly. Muscle fiber diameter on semimembranosus were increased (P<0.05) bycombined treatment of tumeric powder with RA (P0 : 2.83 μm; P1 : 3.50 μm; P2 : 3.24 μm) and RB (P0= 2.85 μm; P1 = 3.28 μm; P2 = 3.33 μm). In conclusion, combined treatment of RA (standard diet) andRB (diet with Swangi fish meal) increased (P<0.05) the size of muscle fiber diameter in majorpectorales and semimembranosus.

Abstract

The objective of the present study was to evaluate the impact of dietary supplementation of formic acid, butyric acid or their combination on carcass and meat characteristics of broiler chicks. A number of 288 day-old-chicks (Lohmann MB-202 meat broilers) were distributed to four groups, including CONT (basal diet with no additive as a control), FORM (basal diet containing 0.1% formic acid), BUTR (basal diet with 0.03% butyric acid) and FORM+BUTR (basal diet with 0.1% formic and 0.03% butyric acid). At day 35 the birds were slaughtered and eviscerated, and from which the breast meat was obtained. Carcass and cut yields of broilers were not different (P>0.05) among CONT, FORM and BUTR birds. The combination of formic and butyric acids increased (P<0.05) the relative weight of back of broilers. Meat pH value was higher (P<0.05) in organic acids treated than in non-treated birds. Organic acids lowered (P<0.05) drip loss of broiler meat. Butyric acid increased (P<0.05) moisture and decreased (P<0.05) the content of meat protein. Formic acid increased (P<0.05), whereas butyric acid and combination of formic and butyric acids decreased (P<0.05) lightness values of breast meat. Yellowness values of meat increased (P<0.05) with organic acid administration. Intense bands of 25 kDa (phosphoglycerate mutase) was observed in most of meat samples from the treated birds, but not in meat from the control birds. In conclusion, dietary supplementation of organic acids was capable of improving the meat quality of broiler meats. The treatments may prevent the pale, soft and exudative (PSE)-like condition in broiler meats.

Abstract

This study aimed to investigate the effect of decocted turmeric on performance, haematological parameters and carcass traits of broilers. Broiler chicks at 11 days of age were allotted to five groups, including T0 (birds drinking 100% water), T1 (25% decocted turmeric + 75% water), T2 (50% decocted turmeric + 50% water), T3 (75% decocted turmeric + 25% water) and T4 (100% decocted turmeric). The study was arranged based on a completely randomized design (CRD), parameters investigated was performance and blood chemistry (leukocyte, total protein, albumin, globulin, uric acid, glucose). The data were subjected to analysis of variance at 5% probability. Decocted turmeric did not affect weight gain, feed and water consumption and feed conversion ratio of broilers. Lymphocytes proportion was higher (P<0.05) in T1, T2 and T4 than in T0 and T3 birds. The heterophils to lymphocytes ratio was lower (P<0.05) in birds receiving decocted turmeric than control. Globulin concentration and albumin to globulin ratio were higher and lower (P<0.05), respectively, in serum of T2, T3 and T4 than T0 and T1 birds. The proportion of heterophils and concentration of serum total protein, albumin, uric acid and glucose were not different among treatments. The weight of breast meat was higher and lower (P<0.05) in T3 and T4 birds, respectively, compared to the control. In conclusion, providing decocted turmeric through drinking water helped to improve stress responses and increased the weight of breast meat of broiler chickens.

Abstract

The experiment was carried out to investigate the effect of turmeric extract on blood parameters,feed efficiency and abdominal fat content in broilers. A total of 100 mixed-sexes Lohman chicks wereused in the experiment set up with completely randomized design of 5 different doses of turmeric extractgiven orally start from day-15 to day-35. The chicks given no turmeric extract were used as a control(T0), whereas T1, T2, T3 and T4 were the chicks given turmeric extract of 200, 400, 600 and 800mg/kg-live BW, respectively. Hemoglobin values of broilers given turmeric extract 800 mg/kg-live BWwas significantly higher (p<0.05) at week-3 and week-4, but not at week-5, compared to broilers giventurmeric extract with lower doses or control group. Turmeric extract did not affect significantly (p>0.05)the concentration of erythrocytes, the levels of hematocrit as well as FCR and abdominal fat content ofbroiler. Turmeric extract seemed to be able to improve the digestion and metabolism (of fat) resulted inenhanced production of hemoglobin in broilers. The hypolipidemic effect of turmeric that could hamperits potential to promote the growth of broilers per se might explain why turmeric could not improve thefeed efficiency of broiler.

Abstract

The study was conducted to investigate the in vitro antibacterial activity and antioxidant-enhancing effect of Bacillus strains isolated from the rumen content of dairy cows. The antibacterial activity of Bacillus strains was assessed against Escherichia colibased on the agar-well diffusion method. To assess the antioxidant-enhancing effect, the Bacillusstrains was mixed (prepared as multi-strains) and used to ferment herbal medicine waste (HMW). The effect was compared with that of commercial probiotic Bacillus subtilis and non fermented HWM. Results showed that each Bacillus strain was able to inhibit the growth of E. coli. Fermentation with mixed Bacillus strains tended (P=0.07) to enhance the 2,2-diphenylpicrylhydrazyl (DPPH) radicals scavenging activity and total phenolics content of HMW. In contrast, fermentation with commercial Bacillus subtilis tended (P=0.07) to decrease DPPH radical scavenging activity and total phenol of HMW. Fermentation with both Bacillus preparations increased (P<0.05) the contents of crude protein and ash in HMW, while crude fat increased  (P<0.05) in HMW fermented with Bacillus subtilis. Fermentation either with Bacillus subtilis or mixed Bacillus strains increased (P<0.05) the fiber content of HMW. In conclusion, Bacillus strains isolated from the rumen content of dairy cows showed antibacterial activity and antioxidant-enhancing effect, therefore, they are potential as feed additive to substitute synthetic antibiotics and antioxidants for broilers raised under tropical conditions.

Abstract

The objective of the present study was to investigate the effect of feed deprivation over the first 48 h post-hatch on the composition of fatty acids in broiler meat. Sixty 1-d-old Ross chicks were divided to two experimental groups, i.e., birds provided access to feed and water ad libitumimmediately post-hatch until d 35 and birds deprived from feed but not from water over the first 48 h post-hatch. Blood for cholesterol analysis was collected on d 34. The same birds were sacrificed on d 36, and immediately breast meat, abdominal fat, heart and liver were collected and weighed.Feed deprivation over the first 48 h post-hatch retarded (P<0.05) growth performance of chickens, but had no impact (P>0.05) on the abdominal fat, fatty acid profile of meat, total serum cholesterol level as well as the weight of heart and liver of broiler. In conclusion, early post-hatch feeding is a beneficial means to enhance the final body weight of broilers without affecting the meat quality.

Abstract

This study was designed to determine the physiological response of blood and immune organs ofbroiler chickens fed on various concentration of dietary black cumin powder (BCP) during the dryseason. A total number of 100 unsexed one-day old Cobb broiler chicks were used and distributed to 5treatments (control, antibiotics and without BCP, 20 g/kg BCP, 40 g/kg BCP and 60 g/kg BCP) and 4replications (5 birds for each). Physiological responses of blood and immune organs were measured at30 day of age. Addition of BCP to broiler ration did not significantly effects on physical properties ofblood (leukocytes count, erythrocytes count, haemoglobin, hematocrit, monocytes, and eosinophils) andrelative weights of thymus and bursa of fabricius, but significantly (P<0.05) increased relative weightsof spleen when compared to control. It was concluded that the black cumin grinds (Nigella sativa) as afeed additive could not change the physical properties of blood, relative weights of thymus and bursa offabricius, but it increased the relative weight of spleen at the level of 60 g/kg BCP, which could reduceadverse effects of infectious diseases in broiler chicken.

Abstract

This study aimed to investigate the effect of two-stage fermented cassava pulp (FCP) on growth, blood parameters, intestinal microbiology and carcass characteristics of broilers. Two hundreds Lohmann broiler chicks were used from days 22 to 38 and allotted to CONT (maize-soybean-meal-based finisher diet), FCP-10 (finisher diet containing 10% FCP), FCP-15 (15% FCP) and FCP-20 (20% FCP). FCP was included into finisher diet at the expense of maize. On day 38, one bird per replicate was blood sampled and slaughtered. Ileal and caecal digesta and duodenal, jejunal and ileal segments were obtained for intestinal microbiology and villi height measurements. Breast muscle was obtained for meat colour determination. FCP-10 had a higher (p?0.05) body weight gain than CONT. Feed intake was highest (p?0.05) in FCP-15 and the lowest (p?0.05) in CONT. Feed conversion ratio was lowest and highest in FCP-10 and FCP-15, respectively (p?0.05). FCP-20 had a lower (p?0.05) abdominal fat than CONT and FCP-10. CONT had lower (p?0.05) serum total triglycerides than FCP-15 and FCP-20. Duodenal villi height for FCP-20 was higher (p?0.05) than that for CONT and FCP-15. The ileal villi height for FCP-20 was lower (p?0.05) than that for CONT and FCP-15. The wings relative weight was higher (p?0.05) in FCP-20 than in FCP-10 and FCP-15. FCP-15 and FCP-20 had higher (p?0.05) L* (lightness) values than CONT. In conclusion, feeding two-stage FCP up to 20% had no deleterious effect on growth, haematological parameters, intestinal microbiology and carcass characteristics. Feeding two-stage FCP at a level of 20% reduced the abdominal fat content and increased duodenal villi height of broilers.
