“…There was no influence of housing systems on cholesterol level, in agreement with other studies (Elerogly et al 2011;Diktas et al 2015;Eleroglu et al 2015) that found negligible effects of housing system on cholesterol level among different chicken genotypes. However, higher cholesterol level was determined in NN than in BNN birds.…”

The present study evaluated the effect of housing system on the morphometrics, serum chemistry and antibody response of dualpurpose chicken genotypes. A total of 156 pullets and 39 cockerels were randomly picked from 18 treatment block groups (3 housing system × 3 genotypes × 2 sexes) according to Randomized Complete Block Design (RCBD). Three genotypes, purebred Naked Neck (NN) and two crossbred Rhode Island Red × Naked Neck (RIR × NN = RNN) and Black Australorp × Naked Neck (BAL × NN = BNN), were compared. Morphometric traits were recorded during rearing period, thereafter, serum chemistry and antibody response were evaluated in pullets. Intensive and semi-intensive chickens were heavier (males, p=0.0012; females, p<0.0001) on week 21. Body length was maximum (p<0.0001) for free-range female chicken. Maximum (p<0.0001) keel length was found in semi-intensive female chickens. Regarding genotypes, RNN and BNN chickens were heavier than NN (males, p=0.0015; females, p<0.0001). Keel length was maximum (p=0.0002) in BNN and NN female chickens. Drumstick circumference were maximum (males, p<0.0001; females, p<0.0001) in NN chickens, shank circumference was maximum (p=0.0150) in RNN and BNN male chickens. Wingspan was maximum (p=0.0029) in NN female chickens. Plasma glucose level was higher (p=0.0008) in intensive female chickens whereas cholesterol levels was higher (p=0.0123) in NN female chicken. Antibody titer against ND was higher (p=0.0204) in RNN female chickens while higher (p=0.0001) antibody titer against IB was found in free-range chickens. Overall, housing system did not impact morphometric traits or serum chemistry. Only a few differences were observed regarding body weight, body and keel length, plasma glucose, cholesterol and antibody response against ND and IB.

“…The application factor did also not signi cantly affect the serum glucose in our work, that is, neither the genotype nor the rearing system was found to be effective on the serum glucose Diktaş et al (2015). andEleroğlu et al (2015) found that glucose levels were similar between those grown indoors and those raised on pasture, like us. But Jin et al (2019) concluded that grazing resulted in reduced glucose levels in the local slowgenotype.…”

“…The measurement was made in a separate room, the chicken was placed on the measuring instrument with its head facing out of the cradle and placed one hand on the breast and waited for 15 seconds for the animal to remain still. If the animal straightened within 10 s, the procedure was repeated, with a maximum score of 600 s recorded for the TI time (Eleroğlu et al 2015).…”

In this study, it was aimed that to evaluate the effects of season, genotype, and various semi-intensive production systems on broiler welfare. Fast-growing and slow-growing broilers were used, different semi-intensive production systems (extensive indoor, free-range, and traditional free-range) were applied according to EU standards, and trials were carried out in spring and summer in Antalya beside the Mediterranean Sea. Some welfare parameters were collected on day before slaughter (81 d for the traditional free-range, 55 d for the other systems). Recorded data were deal with fear and stress parameters, leg health, bruises on the breast and thighs, breast feather dirtiness, and certain blood parameters. Additionally, outdoor use was identified. The proportion of chickens on the outside was higher in spring than in summer, and slow- used more of the outdoor area than fast-. As a conclusion, the high ambient temperature decreased prominently the welfare of the birds, the welfare of the slow-growing chickens was clearly higher than fast- ones and the welfare-improving effect of grazing was limited.

“…Being coherent with the present study, it was determined in the previous studies that body weight of broiler chicks was between 2380 g (Kaynak et al, 2010) and 2356 g (Seremet, 2007). Eleroglu et al (2015) determined rectal temperatures of female and male chicks measured in the sixth week were as 41. (Xie et al, 2015).…”

This study aims to examine the effects of environmental enrichment (EE) practices on some physiological and behavioral parameters of broiler chicks. A total of 280 one-day old Ross 308 mixed-sex broiler chicks with an average initial body weight of 44.5±0.37 g were used in a 42-d trial. Broiler chicks were randomly allocated to 20 pens composed of 14 birds in 1x1.4m sized floor area. Each of the EE treatment consisted of 5 replicate pens (70 chickens per treatment). The treatments were 1) control; 2) perch for EE; 3) ball for EE; 4) mirror for EE; and 5) dust for EE. Final body weights, tonic immobility test results, and rectal temperatures were recorded. Spleen, liver, and bursa fabricius weights were measured. The blood biochemistry of birds was analyzed at the end of the experiment. Besides, gait score test was applied on the 42 nd day of experiment. Body weight gain, lymphoid organ weights and rectal temperature values of broilers were not affected by EE treatments on the 21 st and 42 nd days of the study. At the end of the study, WBC values, tonic immobility values and gait scores of the control groups were found higher than those of the EE groups. HCT and PLT values of the ball groups were found lower than the other groups, concluding that EE improved the welfare of birds.
