ABSTRACT This study was carried out to determine citrus peel oils (orange, lemon, bergamot) as food supplementation in different levels on performance, microflora and morphology in broilers. The trial consisted of 1-day-old male and female Ross 308 chicks (250 male 250 female). The study consisted of 10 groups in total and each group was replicated five times. Experimental diets were prepared by adding orange, lemon and bergamot peel oil levels (1,2 and 3 mL/kg) to basal diet. It was observed that the supplementation of citrus peel oils to the diet improved significantly the feed conversion rate. Especially the lowest feed intake and the best feed conversion ratio were received from broilers which were fed 3 mL/kg of orange peel oil. The study shows that...

The effects of age, litter reutilization, and anticoccidial programs were studied in broilers. The oocyst counts increased with litter reutilization up to third use, and T1 (no anticoccidial drug over the entire 42-day-period) and T4 (anticoccidial medication starting from the first day) showed the highest counts. The scores for Eimeria acervulina increased up to third use of litter and declined by the fourth use. The scores for E. maxima increased from first to second litter use, and from this to third and fourth use. The scores for E. tenella increased from first and second litter use to third litter use, and declined on fourth use. With high coccidial contamination, as in third use litter, the anticoccidial medication starting from the 1st, 7th (T3) and...

ABSTRACT We hypothesized that the supplementation of vitamin C (Vit. C) and coenzyme Q10 (CoQ10) alone or in combination could reduce the negative effects of cold stress in broilers. Four hundred male chicks were exposed for 24 h to cold stress (15 ºC) starting from 15d of age, while a positive control group (PC, 100 birds) was kept under normal temperature condition. The experimental groups under cold stress (four treatments in 5 replicates of 20 birds) were: negative control (NC, basal diet), Vit. C (basal diet + 300 mg/kg Vit. C), CoQ10 (basal diet + 40 mg/kg CoQ10) and Vit. C plus CoQ10 (basal diet + Vit. C+ CoQ10at above mentioned doses). Vit. C or CoQ10 supplementation were restored (p<0.01) performance and lowered (p<0.01) ascites mortality....

ABSTRACT Present study evaluated carcass and meat quality attributes of broilers, broiler breeders and Aseel chickens. Sixty birds from each chicken genotype (broiler, broiler breeder and Aseel chickens; five-wk-old broilers and 60-wk-old Aseel chickens and broiler breeders) were evaluated. Birds were maintained under similar environment for 21 days, and then slaughtered to analyze their carcass qualitative and organoleptic characteristics. No carcass yield differences were detected among genotypes. Aseel chickens had heavier neck, followed by broiler breeder and broiler (p<0.0001). Higher liver (p<0.0001), intestine (p<0.0001), ribs and back (p=0.0014) yields were obtained in broilers than in broiler breeders and Aseel chickens. Females showed...

Recently, organic broiler chicken production has received more attention worldwide. This study has carried out an economic analysis to compare the profitability of organic versus conventional growing systems per unit of broiler meat production. To achieve this goal, 400 slow-growing broiler chickens (Hubbard Red-JA) were reared in an organic production system, and the same number of fast-growing birds (Ross-308) in a conventional system. The profitability was deduced with an economic analysis that compared total costs and net income. Results showed that organic broiler meat can cost from 70% to 86% more with respect to variable and fixed costs when compared with conventional production. The main reasons for the higher cost of organic broiler meat were...

Two experiments (EXP 1 and EXP 2) were conducted to compare soybean oil (SO) and semi-refined rice oil (RBO) added to broilers diets. In EXP 1, 400 male Ross x Ross 308 broilers were reared in battery cages, and their performance was evaluated. A metabolism assay was performed. In EXP 2, 1344 broilers from the same strain were reared in floor pens with rice husks litter. In addition to performance, carcass yield and meat oxidative stability were evaluated. In both EXP, birds were distributed in a 2x4 factorial arrangement, with two types of oils (SO or RBO) and four oil inclusion levels (1%, 2.5%, 4%, or 5.5%). Two periods were considered: starter (1 to 21 days of age) and grower (22 to 42 days). In both EXP, oil type had no influence on starter...

This experiment was conducted to evaluate the effect of some feed restriction regimes on the performance, carcass characteristics and hematological values of broiler chickens. A number of 480 one-day-old Cobb broilers were distributed into 24 floor pens and reared for 42 days. A basal diet was formulated according to the NRC (1994) recommendations for starter (1-11 d), grower (12-28 d) and finisher (29-42 d) periods. The restricted birds were fed 8 h per day from 7 to 21 (R7-21d), 14 to 28 d (R14-28d) or from 21 to 35d (R21-35d), while the control birds were fed ad libitum. Birds and feed were weekly weighed, and dead birds were submitted to necropsy to determine the cause of death. At the end of experiment, blood samples were taken from 3 birds per pen,...

The study focuses on various types of food safety risks: biological (zoonoses), chemical (chemical treatment of the meat) and technological (use of genetically modified feed). The emphasis was on how the perceived risks affect the purchase intentions in the case of broiler meat. In the case of each risk products the attitude-level variables had importance in explaining the buying intentions. The heterogeneity of the respondents regarding the purchase intentions of risk products was analysed by latent class logistic regression that included all three risk products. About 60% of the respondents belonged to the group of risk avoiders in which the purchase intention of risk food was significantly lower than in the second group of risk neutrals in which 64% of...

Estimating the value consumers place on farm animal welfare (FAW) can predict the extent to which consumers are ready to support policy changes aimed at improving the welfare of farm animals and developing animal-friendly production systems that can also compete on markets. This study aimed at exploring consumer preferences and willingness-to-pay (WTP) for broiler meat in Germany which is certified as having been produced under a system that caters for FAW. In addition, logistic and linear regression models were estimated to examine the factors affecting consumers’ decision to buy certified FAW products. The data was obtained from a survey of 300 German broiler consumers, which was designed using the contingent valuation methodology. The results showed...

ABSTRACT Broiler pure lines are valuable breeding species and morphometric traits are advantageous for the selection of breast yield since they could be applied practically and without any negative impact on welfare. In this study, live weight (LW), carcass weight and ratio (CW and CR), breast weight and ratio (BW and BR), abdominal fat weight and ratio (AFW and AFR), morphometric traits such as breast width, length and index (BWD, BL and BI) were investigated in broiler pure lines. The research material consisted of 3 dam (A1, A2 and A3) and 2 sire (B1, B2) pure lines of 42 days of age. LW, CW, BW, AFW, AFR, BR, BL, BWD and BI values were different between the two lines (p<0.05). LW, CW, BW and BI were higher in sire lines. The relationship between...

In this study, costs and benefits of two Salmonella control options in broiler production were compared. The first option was to control Salmonella as set by Council Directive 92/117/EEC, so-called Zoonosis Directive. The second option was more intense control programme, the so-called Finnish Salmonella control programme. The costs of controlling Salmonella in primary and secondary production and the direct and indirect losses due to Salmonella infection in humans in both options were compared. The national control option was found to be economically feasible. One prevented loss of life covered all the control costs of the national programme.

In order to estimate the crude protein (CP) equivalence value of Natuzyme-p (NP) enzyme by using regression response equations, two experiments were carried out using Ross (308) broiler chicks. Graded levels of dietary CP (while amino acids levels were kept constant) and NP enzyme were used to derive the regression equation in the first experiment. Four levels of dietary CP and NP enzyme were fed to 160 feather-sexed male broiler chicks during the starter (0-28 d of age) and grower (28-42 d of age) period. Each diet was offered to four replicates of five chicks in a completely randomized design. Results obtained in experiment one failed to fit a regression equation between BW, dietary CP levels and NP enzyme. In experiment two, graded levels of CP changed...

The objective of this study was to establish a specific, sensitive and rapid PCR approach for the detection of Clostridium sp. at the genus level. Clostridium sp. in the duodenum, jejunum, ileum and cecum of broiler chickens were analyzed by 16S rRNA genes. The PCR detected the presence of Clostridium spp. in naturally contaminated intestinal samples. For the total gastrointestinal segments, 53.125, 65.625 and 59.375% samples were positive for naturally occurring Clostridium spp. at the ages 4, 14 and 30d, respectively. Analysis of the microbial contents indicated that Clostridium sp. was not consistently detected in all intestinal segments. These results can put in evidence the hypothesis that Clostridium spp. may be interfering in health and performance...

To know the Spanish homes reasons of purchasing broiler meat a survey of 1,000 families, by means of a 13 question interview, was carried out during 2007. After processing the information it was concluded that Spanish families purchase food an average of 2.34 times/week, 95% of which do not exceed 100 € and, with the exception of more than 400 € purchases, in more than 90% of which broiler meat accounts for more than 14% of the spent budget. Broiler meat is bought near home, in butcher’s shops or supermarkets, with purchases via telephone or the internet being marginal. The main declared benefits of consuming broiler meat were the low fat content, being a healthy meat, and being proper in a healthy diet. Surprisingly, 72% of interviewees did not see any...

An experiment with 400 one-day-old male chicks (Ross) was conducted to evaluate the effects of different Na levels (0.10, 0.22, 0.34 and 0.46%) and different cation/anion balances (Na+K-Cl) (100, 150, 200, 250 and 300 meq/kg) in pre-starter diets on broiler performance. The corn and soybean-based diets had 22% crude protein and 2,900 kcal/kg metabolizable energy and were fed ad libitum. Performance data showed a positive quadratic effect of increasing Na levels on feed and water consumption, weight gain and feed conversion. Na+K-Cl also had a quadratic influence on feed intake and weight gain. None of the effects tested affected the amount of water measured in excreta. Derivatives of obtained regression equations pointed to optimal Na levels of 0.45% for...
