Growth Performance and Carcass Characteristics of Slow Growing Hubbard Red JA57 in Different Raising Systems
No full textIn this study, Hubbard Red JA57 genotype, which growing slowly in mixed sex, were examined in indoor (KYS) and free-range raising systems (SYS). The study was carried out at the Kahramanmaraş Sutcu Imam University (KSU), Animal Production Application and Research Center for 12 weeks. Each treatment was represented by 3 groups containing 28 male chick (total 168 chick). During the indoor treatment, the chicks were raised in floor pens in a conventional house (3.7 birds/m2). In the free-range treatment, the chickens were housed in a similar indoor house (3.7 birds/m2); in addition, they also had a free-range clover paddock (0.9 bird/m2). All birds were provided with the same diets as ad-libitum. In two different raising systems; live weight, feed consumption, feed conversion ratio, survival rate, carcass and parts rates, edible giblets weight and rates, testicular weights and rates, rectal temperature and tonic immobility were examined. Results showed that the weekly feed conversion ratio was found to be significant at the 11th week and the additive feed conversion ratio at the 12th week. The difference between the groups in terms of rectal temperature and tonic immobility values, testicular weights and rates were found to be significant. In terms of average interaction; While the average rates of hot carcass, cold carcass, back, breast meat and neck were the same, the averages of thigh, bony breast and wing ratios were different. The highest mean abdominal fat rate was found in KYS females, the highest average gizzard rate in SYS females, the highest mean liver in KYS females, and the highest heart weight in SYS males
Importance of Melatonin on Poultry
No full textWOS: 000457128900020Intensive production practices, faulty maintenance and feeding, unsuitable keeping conditions, antinutritional factors in feeds and similar abnormalities lead to irregularities in both hormone and enzyme systems in poultry. Especially, due to disorders in endocrine system, a specific hormone, melatonin, can not be produced or underproduced, and thus its metabolic and physiological functions are negatively affected in the organisms. Melatonin (ML) is one of the important hormones that prevent metabolic and physiological disorders in poultry but does not attract attention by poultry scientist. ML regulates the brain's biological clock, acts on respiration, circulation, excretion, reproduction and immunity system. ML helps regulate feed consumption, energy metabolism and body heat. It also provides elimination of free radicals in the body. ML stimulates growth hormone secretion and, thus, effects growth performance of poultry positively. It is considered necesary to focus more effectively on the melatonin hormone, which is a positive contribution to animal welfare by correcting metabolic-physiological disorders in poultry. In this review, the definition of melatonin, its interaction with other hormones, its effect on the physiological and metabolic functions of poultry were examined
The Effect of Different Production Systems on Some Morphological Characteristics and Asymmetry in Atak-S Cocks
No full textThe aim of this study was to determine the effect of housing system on morphological characteristics of Atak-S cocks reared in closed and free range systems. Cocks were fed with standard feed according to feeding program for seventeen weeks. In order to determine the effect of the housing system on some morphological features and asymmetry, Crest length (İU), Crest width (İG), Eye width (GG), Nose length (BU), Face width (YG), Wattle length (SU), Beak length (GU) in bilateral features, measurements were made from the right and left sides on the head of the cocks. Furthermore, foot features such as Width of tarsometatarsus at the joint with tibiotarsus (EG), Length of tarsometatarsus (TU), Width at 1 cm above the spur of tarsometatarsus (MG1), Width of tarsometatarsus at the spur (MG2), Length of the back toe (AP), Length of the outer toe nail (DT), Length of the fourth phalanx of the outer toe (D4), Length of the third phalanx of the outer toe (D3), Length of the mid toe nail (OT), Length of the fourth phalanx of the mid toe (O4), Length of the third phalanx of the mid toe (O3) measurements were taken on the right and left feet of the cocks. All measurements were made in millimetres (0.01 mm) using a digital caliper. Relative asymmetry (GA) and fluctuating asymmetry (DA) values were calculated for the features showing bilateral symmetry. According to the statistical analysis on the obtained data, the morphological characteristics of ATAK-S cocks were not affected by the housing system, and that the characters underlined in both housing conditions developed in the same way as right and left
