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.

The results of the research into the microbiological contamination of litter used by broiler chickens are presented. Litter samples were taken prior to the introduction of chicks (day 0) and in 7-day intervals until the end of the fattening period. The total numbers of aerobic mesophilic microorganisms, yeasts, moulds and Clostridium perfringens spores, and the presence of bacteria of the Salmonella genus were determined. The total microbial count in newly laid litter was 7 log10 CFU/g, which increased to 9 log10 CFU/g by the 4th week. However, at the end of the 5th week, it was at the same level as in newly laid litter. C. perfringens spores, presumably originating from chicks? faeces, were first detected on day 7. In the next 7 days their number increased, reaching 3-4 log10 CFU/g, and remained at approximately same levels until the end of the research. The initial mould contamination was 5-6 log10 CFU/g. However, from day 21 moulds were not isolated, but only yeasts of the Saccharomyces genus. It is supposed that these were deposited with chicks? faeces, due to their presence in complete broiler feed. No bacteria of the Salmonella genus were ever isolated from the litter. In conclusion, the total numbers of microorganisms in deep litter reach their peak in approximately a month, which is followed by their decrease. Deep litter is a favourable environment for probiotic yeast cultures. Added to feed intended for broilers, they can positively influence the microbial composition of litter, providing healthier environment to fattening broilers.

Slow growing chickens of genotype Redbro, were reared in two systems in order to determine the effect of duration of fattening on values of slaughter yields/dressing percentages and shares of main carcass parts. Fattening of chickens in chicken coop to age of 84 days had considerable effect on increase of slaughter yields: "Conventional processing"(83.59%), "Ready to roast"(77.22%) and "Ready to grill"(67.17%) compared to 42nd day of age (82.21; 74.87 and 65.42%). Redbro chickens reared on free range had lower body masses compared to chickens reared from chicken coops in all investigated ages. Beside significant increase of body mass, longer fattening period influenced considerably decrease of share of back, pelvic and wings. In both rearing systems, prolonging of fattening had statistically significant effect on increase of share of abdominal fat. .

AbstractCarvacrol, a primary constituent of plant essential oils (EOs), and its antimicrobial activity have been the subject of many in vitro studies. Due to an increasing demand for alternative antimicrobials and an emerging number of antibiotic resistant bacteria, the use of essential oils has played a major role in many recent approaches to reduce Campylobacter colonization in poultry before slaughter age. For that purpose, the reducing effect of carvacrol on Campylobacter jejuni prevalence in broilers was determined in vivo in an experimental broiler chicken model during an entire fattening period. Carvacrol was added to the feed in a concentration of 120 mg/kg feed four days post hatch until the end of the trial. In this study, we demonstrated a statistically significant decrease of C. jejuni counts by 1.17 decadic logarithm (log10) most probable number (MPN)/g in cloacal swabs during starter and grower periods (corresponding to a broilers age between 1 and 28 days). Similar results were observed for colon enumeration at the end of the trial where C. jejuni counts were significantly reduced by 1.25 log10 MPN/g. However, carvacrol did not successfully reduce Campylobacter cecal colonization in 33-day-old broilers.

Effect of alum-treated groundnut (Arachis hypogea) shell (ATGNS) meal was studied on the blood chemistry and carcass characteristics of broiler chickens. Two hundred and forty (240) day-old broiler chicks of Anak strain were used for the study in a completely randomized design for eight weeks. The chicks were allotted into six groups of forty chicks each and further divided into four replicates of ten chicks each.Groundnut shell (GNS) was processed by soaking it in water containing alum in ratio 1kg of groundnut shell: 15 litre of water: 600g of alum for three, four, five and six days. Wheat offal was included at 10% in T1 as positive control, 4% wheat offal and 6% untreated groundnut shell (GNS) in T2 as negative control, and 4% wheat offal with 6% treated GNS in treatments 3, 4, 5 and 6 at three days, four day, five days and six days of processing respectively. Results on haematological parameters were not significantly (p>0.05) different except mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). Birds in T5 performed better than others in mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) with highestvalues of 123.83% and 41.93pg respectively, while birds in T3 had the lowest values of 115.28% and 39.05pg in the two parameters respectively. There were significant (p<0.05) differences in serum total protein, albumin and globulin, while other parameters measured showed no significant (p>0.05) differences in serum biochemical studies. Birds fed treatment 1 (T1) had the highest values of 3.95 and 2.72g/dl in total protein and globulin respectively, while the lowest values 2.55 and 0.97g/dl were obtained from birds in T6 respectively. Cut-up parts showed significant (p<0.05) differences in head, neck, back and thigh across treatment means with the exception of other parameters considered. The live weights of birdson processed groundnut shell meal, although not significantly (p>0.05) different, were better (p<0.05) than those on untreated groundnut shell meal (T2). Birds in T6 had the highest values (2.95, 4.60 and 12.53%) in head, neck and thigh respectively. The highest weight (18.02%) of back was recorded in T1. Birds in T4 had the highest values of 19.60 and 4.20% in breast muscle and shank respectively, while those in T3 recorded the lowest (14.65%) in breast muscle, and those in T2 had the lowest (3.56%) in shank. The results in conclusion, showed that alum-treated groundnut shell(ATGNS) could replace wheat offal at 6% level of inclusion by improving carcass yield as well as maintainingblood profile of broiler chickens.
