The effects of bovine oviductal proteins on bull sperm viability, acrosome reaction and motility were studied. Motile frozen/thawed spermatozoa from Percoll gradients were incubated with 1.0 mg/mL oviductal proteins (>8 kDa) extracted by ammonium sul

Spermatozoal motility and enzyme leakage during cryopreservation of ram spermatozoa was evaluated in the presence and absence of antifreeze proteins (AFP). Loss of spermatozoal motility due to the cryopreservation process was reduced by 10% in the pr

A chemically defined ram semen diluent (RSD-1) has been developed. RSD-1 maintained spermatozoal motility of diluted semen containing approximately 800 million spermatozoa ml −1 during cooling to 15°C and its storage for 1 h. Motility was further

A total of 36 Saanen X Angora goats, 18 female and 18 castrate male, ranging from less than 1 year to approx. 5 years, and with a mean hot carcass weight of 15.8±3.69 kg, were evaluated as representing a ‘commercial’ goat carcass. Castrate males

Eighteen intact male Saanen goats (BW 5 to 115 kg; hot carcass weight 2 to 52 kg) and 19 females (BW 17 to 64 kg; hot carcass weight 8 to 32 kg) were studied. Newly born female goats were not available to cover the light end of the female range but m

Chemical antioxidants and catalase have been shown to be ineffective in improving the motility of ram spermatozoa in a chemically-defined diluent (RSD-1). In an attempt to identify the biochemical basis of this observation, the activity of aromatic a

The effects of five antioxidants--Vitamin E (VE), butylated hydroxyanisole (BHA), n-propyl gallate (n-PG), deferoxamine mesylate (Desferal) and catalase (EC 1 . 11 . 1 . 6)--on the maintenance of motility of ram spermatozoa in a chemically-defined ra

Summary A field trial was conducted to compare four injection regimes of corticosteroids to induce parturition. The treatments were: I 20–25 mg intramuscular injection of dexamethasone trimethyl acetate; II 20 mg dexamethasone trimethyl acetate ini

The body composition of 20 Romney, 20 Dorset × Romney, and 20 Cheviot ewes culled from hill country was determined. Ewes from the different breeds did not differ greatly in mean liveweights at slaughter (51,48, and 49 kg respectively). On average, C

Investigations have been made into possible spectral interferences at fat, protein and water wavelengths of the Super-Scan (infra-red meat analyser) due to absorbance by phosphorus (a natural constituent of bone) at the carbohydrate wavelength. Instr
