Head-only followed by cardiac arrest electrical stunning is an effective alternative to head-only electrical stunning in pigs.

Many small slaughter facilities use head-only electrical stunning to render swine unconscious and insensible to pain before slaughter. Head-only electrical stunning is a reversible procedure that is optimally effective for approximately 15 s after stun completion. In many small North American slaughter plants, the authors have observed hoist speeds that are too slow to achieve a short enough stun-to-bleed interval to maintain insensibility through exsanguination.

Factors associated with Salmonella prevalence on pork carcasses in very small abattoirs in Wisconsin.

The U.S. Department of Agriculture has expressed concern over Salmonella prevalence on pork carcasses.

Effect of storage on sperm membrane integrity and other functional characteristics of canine spermatozoa: In vitro bioassay for canine semen.

The effect of storage of canine semen on sperm membrane integrity, as determined by the hypoosmotic swelling test, and on other functional characteristics of the canine spermatozoa was evaluated by established procedures. The results of this study indicated that storage of canine semen at a chilling temperature of 5 degrees C for 24 h did not significantly impair the physical and functional characteristics of the canine spermatozoa. The overall mean percentage of motility, hypo-osmotic swelling response, which assessed sperm membrane integrity, acrosome-reacted spermatozoa, acrosomal defects, and the percentage of live spermatozoa, did not significantly differ between the fresh and chilled semen samples.

Pelvic growth, calf birth weight and dystocia in Holstein x Hereford heifers.

The pelvic area was measured in 129 Holstein x Hereford heifers at 10, 16 and 22 months of age. The heifers were fed an all forage diet. Pelvic growth was not linear over time, changing from an increase of 0.

Unusual Bone Healing in a White-tailed Deer.

Two sequential fractures in the left hind leg of a deer and their treatments are described. The first, a tibial fracture was treated using an intramedullary pin with full cerclage wires supported by a plaster cast. This fracture healed uneventfully.
