Objective: Hydatid cyst or cystic echincoccosis (CE) is an important medical and veterinary problem in the world, especially in Iran. Domestic intermediate hosts are a major reservoir for the disease in humans. The aim of this study was to determine the prevalence of hydatid cysts in slaughtered animals in Isfahan, central part of Iran.
Methods: In this cross-sectional study performed from 10 May 2009 to 10 May 2010, a total of 196,325 animals (89,651 sheep, 93,050 goats, 9,112 cattle and 4,512 calves) were inspected macroscopically for hydatid cysts.
Results: Prevalence rate of CE in sheep, goats, cattle and calf was 16.4%, 3.1%, 6.5% and 8.2%, respectively. In all cases, the prevalence in female cattle and sheep was more than in males (P < 0.001). There are significant seasonal pattern for hydatidosis only in sheep (P < 0.001) and the highest prevalence of cysts was seen in autumn and winter seasons. The fertility of cysts in the liver of sheep (77%) was higher than in lungs (47.9%), but was higher in lungs in cattle (44%). Most condemnation cases were seen in lung of sheep (27.1%).
Conclusion: It appears that sheep are the most important intermediate hosts for E. granolusus in this area.

The objective of this Scientific Opinion is to assess the hazards and welfare consequences associated with the slaughter of horses for human consumption. The entire slaughter procedure, from arrival at the slaughterhouse until death, is divided into three phases: Phase 1 - pre-stunning, Phase 2 - stunning and Phase 3 - bleeding. Phase 1 includes the following processes (in chronological order): (a) arrival, (b) unloading of the animals from the vehicle, (c) lairage, (d) handling and moving to the stunning area and (e) restraint before application of the stunning method.

Although naturalists have devoted attention to cetaceans since Antiquity, it was only in the 19th century that cetology underwent a true explosion. Three key cetological works of this period are The Natural History of the Sperm Whale (1839) by Thomas Beale, The Whaleman's Adventures in the Southern Ocean (1850) by Henry Cheever and The Seals and Whales of the British Seas (1881) by Thomas Southwell. Importantly, these three works did not only represent fundamental compendia of scientific knowledge of cetaceans, but also had a crucial role in awakening a cetacean protection consciousness.

To improve the quality and yield of the Korean beef industry, selection criteria often focus on estimated breeding values for carcass weight (CWT), eye muscle area (EMA), backfat thickness (BF), and marbling score (MS). This study estimated genetic parameters and assessed the accuracy of genomic estimated breeding values (GEBVs) using SNP weighting methods. We compared the accuracy of these methods with the genomic best linear unbiased prediction (GBLUP) and various Bayesian approaches (BayesA, BayesB, BayesC, and BayesCPi) for the specified traits.

Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high-performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for optimal bone development has been little addressed so far.
