We evaluated the cortisol response of adult female eland (n=8) that were handled in hydraulic chute daily or 3×/week. Females were divided into two groups and each group (n=4) successively received two estrous cycle synchronization treatments: (1) two injections of prostaglandin (PG-PG) F2α at 11 day intervals and (2) oral administration of altrenogest for 7 days and an injection of PGF2α on day 7 (Alt-PG). Blood samples were collected 3×/week during the synchronization (Synch) and expected luteal phase (Nonintensive) periods, and daily during the expected time of induced (Intensive 1) or natural (Intensive 2) estrus. Overall, mean cortisol levels were highest during Intensive 1, followed by Intensive 2, Synch and Nonintensive periods. Individual eland were the most significant source of variation for cortisol level. The frequency of handling and the synchronization treatment significantly affected cortisol levels in 3/8 and 4/8 females, respectively. In conclusion, in response to increased frequency of handling, eland cortisol levels rose transiently and returned to baseline within few days after more intensive handling. Thus, the eland females were tolerant to and recovered from the effects of repeated daily handling.

Droëwors (dried sausage) is a unique dried meat product from South Africa, which is not smoked, fermented, nor is nitrite used in its production. The objective of the study was to compare the quality parameters and consumer acceptance of common eland meat droëwors with different quantities of added beef fat. Three treatments containing either 10, 15, or 20% (by weight) added beef fat were compared regarding chemical composition, fatty acid profiles, and sensory properties.

The effects of immunocastration, pelvic suspension and wet ageing on the meat quality of the longissimus lumborum et thoracis (LTL) and biceps femoris (BF) muscles of male common eland were evaluated. Ten subadult males were either immunocastrated (n = 5) or remained intact (n = 5) throughout a four-month growth trial, after which their carcass sides were randomly allocated to either pelvic- or Achilles-suspension. The LTL and BF were further aged for 14 days, measuring changes in the physical quality weekly.

Drying kinetics and changes in proximate composition, pH, salt content, water activity (a) and lipid oxidation through processing of salami made using five different game meat species were evaluated and compared to pork. Eight batches of salami from each species were made and sampled for analysis throughout processing. Processing time was a significant factor on all measured attributes whilst species affected (P ≤ .
