Pig Trucking & Handling – Stress and Fatigued Pig
نویسنده
چکیده
Stress in the period during transport and around slaughter is known to influence the physiological and biochemical processes in pigs (Adeola and Ball, 1992). Pigs that become non-ambulatory without obvious injury, trauma or disease and refuse to walk, during loading, transport, unloading or while in the lairage are considered fatigued. Literature available on pig transport and slaughter suggest recumbent pigs can result from both acute stress/acidosis or physical exhaustion/glycogen depletion or a combination of the two mechanisms. Fatigued pigs, by industry accounts, tend to be of heavy muscled, high lean genotypes and newer genetic lines may be more susceptible to heat stress (Brown-Brandl et al., 2001).

Karyotype of Hairless Guinea pig
Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...
متن کاملEffect of Matricaria chamomilla extract on the electrically stimulation of ileum of guinea-pig in invitro model
Previous studies indicate that Matricaria chamomilla (MC), a folk remedy plant, is very useful in the treatment of spasmogenic bowel diseases but the way of its action is not clear. For this purpose, we studied the effect of MC extract on the electrically activation in Guinea-Pig ileum in an invitro model. We used guinea pig in this study. After of kill, we brouhght out a piece of ileum and fix...

متن کاملEffect of Aqueous-Ethanolic Extract from Rosa damascena on Guinea Pig Isolated Heart
Objective(s) In the present study, the effects of aqueous-ethanolic extract from Rosa damascena on heart rate and contractility were examined. Materials and Methods Isolated guinea-pig hearts were perfused through aorta in a Langendorff mode. Heart rate (HR) and contractility were determined in the presence of four concentrations of the extract (0.1, 0.2, 0.4 and 1.0 mg %) and isoprenaline (...
