This study investigated the effects of immunocastration and slaughter age on the carcass yield performance of intensively farmed common eland males. Eighteen male eland (five immunocastrated juveniles, three intact juveniles, five immunocastrated sub-adults, and five intact sub-adults) were finished for four months, after which their carcass, offal, primal cut, and individual muscle yields were determined. Juveniles were ~6 months of age at the start of the experiment, while sub-adults were ~1.5 years old. Primal cuts were dissected to determine the percentage yields of meat, bones (with tendons), separable fat, and trimmings. Immunocastration had no effect on offal or carcass yields. While sub-adults had increased individual muscle yields, juveniles had greater proportionate yields of primal cuts and a greater total high-value: low-value meat ratio. Whilst slaughtering younger male eland could provide additional economic advantages, this should be considered being against changing marketing trends.

The aim of the study was to determine the relationship between slaughter weight (SW) with body components and liner body measurements and investigate the coefficient of correlation between slaughter weight with body component and liner body measurements to select the best regression equation. Data on liner body measurements (height at wither and at hips, heart girth, body length, height and width of hump, height at fall and hind legs, body sheath height, height at hooks, barrel circumference, width of face, length of face and tail circumference) and slaughter weight of body components (Hot Carcass Weight (HCW), Empty Body Weight (ESW), Internal Offal (IO) and External Offal (EO)) were collected from 62 Hararghe cattle at Haramaya University abattoir. ESW was calculated as SW with less gut contents.

Sheep and goat influence the socioeconomic sustainability of rural communities in tropical countries, but parasitic diseases and in particular are responsible for their low productivity. The occurrence of in most affected regions of the world has been associated to the presence of stray dogs in the grazing area, which play vital roles in the life cycle of the parasite and poor disposal of contaminated and seized offal, organs, and carcasses. The aim of this paper is to systematically review the epidemiology of infection in sheep and goats in the tropics between 2010 and 2022 through the analysis of published qualitative and quantitative data on prevalence, risk factors, organ distribution, and interventions.

Considering that, in 2010, the European Commission determined the current Australian monitoring programme to be equivalent to the EU requirements for microbiological monitoring further to an EFSA scientific assessment, the current and proposed programmes were described and the total number of alerts was compared using a probabilistic modelling approach. In the current programme, only beef and sheep carcasses are monitored using three-class moving window sampling plans, while in the proposed programme, carcass, bulk meat, primal and offal are monitored using four two-class sampling plans and testing is excluded.

Asparagopsis taxiformis (Asparagopsis) has been shown to be highly efficacious at inhibiting the production of methane (CH4) in ruminants. To date, Asparagopsis has been primarily produced as a dietary supplement by freeze-drying to retain the volatile bioactive compound bromoform (CHBr3) in the product. Steeping of Asparagopsis bioactive compounds into a vegetable oil carrier (Asp-Oil) is an alternative method of stabilizing Asparagopsis as a ruminant feed additive.
