The Impact

Cold truck transportation is considered one of the most integral parts in a food processing chain. However, countless cases of product spoilage and food poisoning incidents have proven that temperature control during transport has been neglected. Literature on the impact of temperature during distribution is scarce. The objective of this study was to investigate the impact of various transportation temperatures and travel duration on the meat quality and microbial population of broiler chicken breast muscle. Sixty broiler chickens (42 days old) were slaughtered and eviscerated; they then had their breast muscles removed (each bird provided two breast muscle samples: left breast and right breast), which were wrapped in plastic film. All 120 packed boneless breasts (PBBs) were then placed at −18 °C for 24 h. After 24 h, the 60 PBB samples were subjected to transportation for 1 h at 4 °C (20 PBBs), 10 °C (20 PBBs), and 15 °C (20 PBBs) while the remaining 60 samples were transported for 5 h at 4 °C (20 PBBs), 10 °C (20 PBBs), and 15 °C (20 PBBs) before analyses. The samples transported at higher temperatures exhibited higher populations of coliform and Salmonella than those transported at lower temperatures. A significant impact of the transportation duration on the Salmonella population was only observed in samples transported at 4 °C for 5 h. However, a significant impact of transportation temperature on color was only recorded for the redness (a*) values, where the samples transported at higher temperatures exhibited higher redness (a*) values. Significant increases in lightness (L*) and yellowness (b*) values as well as decreases in redness (a*) and pH values were recorded in samples subjected to longer durations of transportation across all the temperatures observed in this study.

The aim of the study was analysed the effect of humic acids separately and humic acids in combination with phytobiotic as garlic and oregano powder on amino acid (AA) profile of the most valuable parts of Ross 308 chicken. A total of 200 pcs Ross 308 broiler chickens of mixed sex were randomly divided into 4 groups (n=50): control group (C) without supplementation, experiment group E1 (2% humic acids), E2 (80% humic acids and 20% garlic powder) and E3 (90% humic acids and 10% oregano powder). Fattening period lasted for 42 days and all groups were kept under the same conditions. After slaughter, the AA profiles of breast and thigh samples were determined. In comparison with control group, 6 out of 10 AA was significantly affected (p ≤0.05) by used dietary supplementation – Met, Cys and His in thigh and Leu, Phe, His and Arg in breast muscle. AA composition of breast muscle was positively affected mainly by humic acids and 10% oregano powder supplementation (E3), while thigh muscle by humic acids and 20% garlic powder (E2). The highest obtained AA in breast muscle was Leu (2.02 g.100 g-1) in E3 group and thigh muscle His (1.15 g.100 g-1) in E2 group (p ≤0.05). In conclusion, humic acids and 10% oregano powder supplementation (E3) elicited to the best AA profile of chicken breast muscle but also the worst AA profile in thigh muscle so the effect of such a supplementation is disputable. On the other hand, humic acids and 20% garlic powder supplementation resulted into slight increase of AA in both breast and thigh muscle (E2).

Positive Effect

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

Context Selenium (Se) is an essential trace element and plays pivotal roles in poultry nutrition. Aims The present study was designed to compare the impact of dietary supplementation of different sources of Se on growth performance, Se concentration of breast meat, and immune response of broiler chickens. Methods In total, 300 1-day-old as hatched broilers were randomly allocated to six dietary treatments, with five replicates of 10 birds per each. The experimental diets were as follows: (1) corn–soybean meal-based diet supplemented with 0.30 mg/kg of sodium selenite, (2) basal diet supplemented with 0.30 mg/kg of Se-enriched yeast, and (3–6) basal diet supplemented with 0.15, 0.30, 0.90 and 1.50 mg/kg of nano-Se respectively. Humoral immunity was assessed by antibody titer against a 5% sheep red blood-cell suspension and cellular immunity was measured by administration of phytohaemagglutinin-p at 38 days. Key results Results indicated that during the periods from 1 to 10 days, from 11 to 24 days, from 25 to 42 days and from 1 to 42 days, average daily gain, average daily feed intake, and feed conversion ratio did not differ among the treatments (P > 0.05). Assessment of orthogonal contrasts at the whole phase of feeding showed that the average daily gain in the broilers fed organic Se was significantly (P < 0.05) higher than that in those fed inorganic Se, as well as nano-Se in comparison to organic Se; such effects were not observed in earlier feeding stages. Se supplementation significantly increased the Se concentration of breast muscle (P < 0.0001). The birds that received 1.50 mg/kg of diet nano-Se showed higher (P < 0.05) total immunoglobulin and IgG titers in primary and secondary immune responses against sheep erythrocytes respectively. Toe web swelling after 24 h and 48 h of receiving phytohaemagglutinin-p was not affected by Se supplementation (P > 0.05). Conclusions In conclusion, the addition of nano-Se gave better results than did inorganic (sodium selenite) and organic (yeast selenium) forms of Se in performance traits, breast meat Se concentration and antibody response of broilers. Implications Novel elemental nanometer particulates, including nano-Se, exhibit new characteristics and a different mode of actions in comparison with organic and inorganic forms of Se sources in poultry diets. Inclusion of the nano form of Se in broiler diets and study of productive performance, immunity responses and meat quality leads to improve balanced broiler diets formulation in view of Se.

The aim of this work was to evaluate the influence of time of broiler chicken transportation and lairage prior to slaughtering on the occurrence of PSE (Pale, Soft, Exudative) meat and Death On Arrival (DOA) under non-commercial conditions in the Brazilian summer. Male birds (n=250) from a commercial line were subjected to different periods of journey (30, 90, and 180 min) and lairage (0, 90, and 180 min) before slaughtering. The occurrence of PSE was higher in broilers subjected to shorter journeys and lairage periods, whereas DOA was more pronounced upon longer periods of transport and lairage. The DOA occurrence percentage was much higher in comparison to commercially available figures, confirming that broiler chickens are very sensitive to both transport and lairage maneuvers.

This study was conducted to evaluate the effects of Tenebrio molitor (TM) oil as a total replacement for palm oil and poultry fat in broiler chicken diets on growth performance, nutrient digestibility, pancreatic enzyme activity, selected blood parameters and the lipid fatty acid compositions of liver and breast muscle tissues. A total of 72 seven-day-old female Ross 308 broiler chickens were used. The birds were randomly distributed into three groups with 12 replicates each, using two birds per replicate for 30 days in metabolic cages. The basal diet was supplemented with 5% palm oil, poultry fat or TM oil. There was no effect (p > 0.05) caused by the dietary oil replacement on the birds’ performance and apparent nutrient digestibility. Liver size (p = 0.033), the concentration of hepatic triglycerides (p = 0.049) and total cholesterol (p = 0.048) were reduced by TM oil supplementation. Furthermore, TM oil supplementation increased n-3 and n-6 fatty acids (p = 0.006; p < 0.001, respectively) in breast muscle tissue. In conclusion, the use of TM oil in broiler chickens’ diets did not show any adverse effects on performance, nutrient digestibility and blood biochemical parameters. Moreover, TM oil supplementation improved the fatty acid profiles of liver and breast muscle tissues.

This study aims to examine the effect of adding nucleotides in broiler rations on the protein mass and calcium mass of broiler chicken reared at different temperatures. The material used was 135 broiler chickens aged 15 days with a weight of 462.20 ± 9 grams of unsex Ross strain and nucleotides imported from China produced by CBH Co. Ltd., China. The study used a completely randomized design (CRD) with a 3x3 factorial pattern with 5 replications. The treatment was carried out at the age of 15-35 days. The treatment given was the first factor adding nucleotides (T0 = nucleotides 0 g/kg feed, T1 = nucleotides 0.5 g/kg feed, T2 = nucleotides 1 g/kg feed) and the second factor was temperature (Heat = S1 = 30 – 32?, Comfortable = S2 = 20 – 23?, Natural = S3 = 24 – 34?). Parameters observed were protein content, calcium content, protein mass, and calcium mass of broiler chicken meat. The research data were analyzed using the F test of variance analysis, if there was a real treatment effect, then Duncan's test was continued. The results showed that there was no interaction between the addition of nucleotides with different maintenance temperatures on protein content, calcium content, protein mass, and calcium mass of meat. Nucleotide 0.05 g had a significant effect (P<0.05) on the protein content of the meat, the natural rearing temperature significantly affected the calcium content of the meat and the comfortable temperature had a significant effect on the protein mass of broiler meat. This study concludes that the addition of 0.05 g of nucleotides can meet the needs of nucleotide synthesis in the body of broiler chickens by increasing the protein content of the meat.

The Impact

The studies aimed to evaluate the impact of milk thistle seeds in broiler chicken feed rations on rearing results, carcass composition and meat quality. The experiment involved 120 broiler chickens randomly allocated to three equinumerous groups (C, MT02, MT23). Each group was divided into five subgroups of eight chickens each. Over the first 21 days of life the birds were fed starter rations, and over the following 21 days received grower rations. Chicken starter/grower diets in groups MT02 and MT23 were supplemented with ground seeds of milk thistle in the amount of 0/2% (MT02) and 2/3% (MT23). It was demonstrated that Silybum marianum added to feed rations over the whole rearing period (group MT23) increased above 3% the birds’ body weight on rearing day 42. (p < 0.05) and decreased about 7% the feed conversion ratio (p < 0.05) in comparison to group C. No effect of feeding on the carcass composition was observed, including on muscularity and fattening grade, although diets containing milk thistle reduced (by 15% and 19% in group MT02 and MT23, respectively) the content of crude fat in chicken leg muscles (p < 0.05). The highest (p < 0.05) content of polyunsaturated fatty acids (PUFA) was determined in the breast (38.06%) and leg (37.63%) muscles of chicken receiving feed rations containing Silybum marianum throughout the rearing period. No effect of nutrition on the evaluated physical properties of muscles was observed, except on the decrease in lightness color (L*) and increase in values a* and C as well as a decrease of water holding capacity of the breast muscles. It was found that Silybum marianum in chicken diets had a positive effect on the evaluated meat flavor characteristics of the muscles. To sum up, based on the study results, including ground seeds of milk thistle in broiler chickens nutrition can be recommended in the amount of 2/3% in starter/grower diets, respectively.

The Impact

Chicken is a major source of animal protein consumption in Indonesia. The problem facing the poultry industry is the incidence of resistance which increases mortality of the chicken production. One of the causes of resistance case is the use of antibiotics in feed additives. The public understanding about the effects of the use of antibiotic growth promoters (AGP) in chickens in antibiotic resistance and the digestive tract of chicken needs to be done to avoid the impact on economic losses and health problems. This study aims to provide an understanding of the effects of the use of antibiotic growth promoters (AGP) on antibiotic resistance and the digestive tract of broiler chickens. This study was carried out at a broiler chicken farm in Sleman, Yogyakarta. Based on the histopathological result of the digestive tract of chickens that were given antibiotics as AGP, there was no inflammation occurs, but the administration of antibiotics caused antibiotic resistance in various type of antibiotics including tetracycline (90% resistance), streptomycin (60% resistance), amoxicillin (50% resistance), erythromycin (80% resistance), and no resistance for gentamycin.

Due to changes in genetics and nutrition, as well as in acclimatization of broiler chickens to the Brazilian climate, temperature values currently accepted as optimal may be outdated. The objective of this research was to update the environment temperatures that characterize the thermal comfort for broilers chickens from one to 21 days of age, under Brazilian production conditions. This research was conducted with 600 COBB birds, which were distributed in five growth chambers maintained at different temperatures during the first three weeks of age. During the experimental period, temperature values were progressively reduced, consisting in five treatments: T2724/21, T30/27/24, T33/30/27, T36/33/30 and T39/36/33. It was observed that the birds maintained in the T30(27-24) treatment presented better performance compared to other environment conditions. Based on the obtained regression models, the environment temperature values that provide greater weighing gain for the broiler chicken growth in the initial period were 31.3, 25.5 and 21.8 ºC, respectively for the first, second and third week of age.
