ÖzetBu çalışmanın amacı, akut gürültünün etlik piliçlerde korku ve bazı stres göstergeleri üzerine etkilerinin araştırılmasıdır. Araştırmada günlük yaştaki 192 etlik piliç (Ross 308) civciv, her grupta 24'er hayvan (12 erkek, 12 dişi) olacak şekilde 4 ayrı gruba iki tekrarlı şekilde rasgele dağıtılmıştır. 42 günlük normal yetiştirme dönemi sonunda hayvanlar ses düzeyi 80, 100, 120 ve 55 (Kontrol) dB olacak şekilde ayarlanmış ses düzenekleriyle 15 dk. süreyle akut gürültüye maruz bırakılmıştır. Analiz sonucunda 100 ve 120 dB gürültü düzeylerinde kortikosteron düzeyinin önemli oranda yükseldiği saptanmıştır (P<0.001). Gürültünün tüm deneme gruplarında kolesterol düzeyini artırmasına karşın, glukoz düzeyini yalnızca 120 dB gürültü düzeyinde artırdığı saptanmıştır. Diğer taraftan, gürültü düzeyinin artmasına bağlı olarak total protein düzeyinin düştüğü ortaya konulmuştur. Tonik Hareketsizlik Testi (TI), TI süreleri arasında önemli bir farklılık olmasa da, akut gürültünün hayvanlarda korku oluşumu üzerine önemli bir etkisinin olduğunu göstermiştir. Bu anlamda TI için gerekli ortalama deneme sayısı ise 100 ve 120 dB gürültü gruplarında (1.4 ve 1.3), kontrol grubuna (1.8) göre daha düşük olarak kaydedilmiştir (P<0.05). Sonuç olarak 100 dB ve üzeri akut gürültünün etlik piliçlerde bazı stres parametrelerini olumsuz etkilediği ve korkuya yol açtığı, bu nedenle hayvanların daha düşük gürültü düzeylerinde bulundurulmaları gerektiği anlaşılmıştır. Anahtar sözcükler: Etlik piliç, Akut gürültü, Stres, Tonik Hareketsizlik Testi The Effects of Acute Noise on Fear and Some Stress Parameters in Broilers SummaryThe aim of this study was to investigate the effects of acute noise on some stress parameters and fear reactions in broilers. Day old 192 broiler chicks (Ross 308) were randomly allocated to 4 different treatment groups containing 24 birds (12 male, 12 female) for two replication. After 42 days regular rearing period, birds were exposed to 55 (control), 80, 100 and 120 dB acute noise for 15 min. with a device hanged to their rooms. Results showed that corticosterone levels at 100 dB and 120 dB noise levels increased significantly (P<0.001). It was revealed that acute noise had increased blood cholesterole levels in all treatment groups, but increased glucose levels only in 120 dB noise group. Conversely total protein level decreased according to increase in noise level. Tonic Immobility Test (TI) in which there were no significant differences between TI durations for all treatment groups, revealed that acute noise has negative effect on fear in broilers. On this context, TI trials were recorded as high in control group (1.8) than 100 and 120 dB groups (1.4 ve 1.3). It was concluded that acute noise over 100 dB have negative effects on some stress parameters and fear in broilers, for that reason broilers should housed at lower noise levels.

“…However, wing-flapping may also be due to excessive pressure applied by the workers of the shackling area, inexperience of the workers, high light intensity, inadequate shackling time, noise, and bends and unevenness in the line (Jones & Satterlee, 1997). The following problems were identified in the present study: Influence of natural and artificial light and noise because the shackling area was outdoors; and shackling time (>60 s) longer than the recommendations (Bedanova et al 2007). According to Haslam (2011), no birds should flap their wings in the shackling lines.…”

Scientific information on the welfare of broilers reared in alternative systems is scarce. The objective of this study was to assess the welfare of free-range broilers using the Welfare Quality® protocol. Free-range broilers reared in ten farms were observed, and measures were made in broilers of five of these farms. The collected data were transformed into scores (0-100), with higher scores indicating better welfare, except for emotional states. Prevalence percentages were calculated for the remaining data. Median (min-max) scores were 81 (63-98) for lameness, 93 (83-99) for hock burn on the farm, 100 (95-100) for plumage cleanliness, 35 (8-70) for podermatitis on the farm, 56 (26-88) for density, 53 (20-53) for dust, 34 (14-67) for litter quality, 93 (41-100) for drinkers, and 100 (100-100) for birds panting or huddling on the farm. The following average (min-max) prevalence percentages were obtained: total mortality 2.0% (1.4-7.2%), culling 0.0% (0.0-2.2%), feed withdrawal time 875 min (715-945 min), water withdrawal time 220 min (170-275 min), dead on arrival at the processing plant 0.00% (0.00-0.01%), broken wings 0%, (0-0%), inefficient stunning 3.9% (1.3-6.7%), pre-stun shock 49.3% (26.7-56.8%), hepatitis 4.5% (1.8-11.0%), bruising 9.3% (6.7-16.7%), and ascites 0% (0-0%). The negative broiler welfare points detected were pododermatitis, litter quality, density, dust, culling, feed withdrawal time, inefficient stunning, pre-stun shock, and hepatitis. The positive points identified were the absence of birds panting or huddling on the farm; low prevalence of lameness, hock lesions, dead on arrival, broken wings, and ascites; good plumage cleanliness scores, and short water withdrawal time.

Answers to Patient, Student, and Clinician Questions About How Animals Are Slaughtered and Used for Food

Do cattle and other animals know they are walking up a chute that will lead to their death?" Many people ask this question, which the author first had to answer when starting work in the cattle industry. From observations at slaughter plants, feedlots, and ranches, the author learned that cattle behavior was the same when entering a chute for vaccination and when entering a chute for slaughter. If cattle knew they would die, their behavior should have been wilder and more agitated at the slaughter plant, but that was clearly not the case. This article canvasses points of ethical and clinical relevance for discussions about human dietary consumption and practice.Animals React to Slaughter Do animals know they are going to be slaughtered? Scientific research has clearly shown that physiological measures of stress during handling are similar at a ranch and at a slaughter plant. Cortisol (stress hormone) levels were in the same range in both places. 1,2,3 If the cattle, for example, knew they were going to die, the stress hormone levels should have been much higher at the slaughter plant.The things that frighten cattle are definitely not the same things that frighten people. Cattle and pigs will often stop and refuse to move through a chute if they see little visual distractions that people do not notice. The distractions might be a coat hung on a fence, sharp shadows from fences that create stripes on the floor, or a dangling chain. 4,5 When the visual distractions are removed, the animals will often move more easily through the chute. Animals are also more likely to refuse to move into a chute that has a dark entrance. The addition of a lamp to illuminate a dark entrance will often make cattle and pigs more willing to enter. 6,7 At a recent start-up at a new plant, the cattle moved easily through the chute during the daytime, but they often stopped and refused to move forward in the evening. I told the people at this plant to watch the cattle very carefully and observe when they stopped in the system. Cattle and other animals will often stop and look at visual distractions. When we conferenced each other by video call, I observed that a small bright light on the corner of the building caused the problem. Turning the light off improved cattle Citation
