This paper reports estimates of genetic parameters for testicular diameter (TDM) from a random-breeding Merino flock maintained at Trangie, N.S.W. Over a period of 4 years, TDM was measured, generally monthly, on 800 rams from four Merino strains and

This paper reports the results of a study, on a random-breeding Merino flock maintained at Trangie, New South Wales, of the genetic relationship between ovulation rate ( OR ) at 4 ages (18, 30,42 and 54 months) and testicular diameter ( TDM ) at 3 ag

Sexual activity, serving capacity, mean number of mounts per serve and mean testis diameter were measured in 286 Border Leicester, BLI (a 'high fertility' sheep related to the Border Leicester) and BLI x Border Leicester rams at 1.5, 2.5 or 3.5 years

Young Merino ewes on five commercial properties in northern New South Wales were supplemented with selenium and their production was compared with untreated flock mates. They were studied from weaning till first lambing at about two years of age. Tre

The serving activity of seven rams in one 20-minute pen mating test followed by two one-hour pen mating tests was recorded. The mating performance of each ram during a single-sire flock mating was subsequently monitored. Mean number of services in th

Relationships of ram serving capacity (a measure of serving frequency in pen tests), testis diameter, liveweight, breed and age with flock fertility were studied in 40 rams joined individually for 7 days at high ewe:ram ratios. Rams were either Borde

Serving capacity was measured in nine Merino rams during two pen-mating tests each of 2 hours duration. Two groups each of four rams were subsequently formed; a high serving capacity group (group H) of mean serving capacity 11.50 � 0.50 (SEM) in tw

Two experiments were carried out to measure the mating behaviour of rams in pens. In the first, rams were tested for 1 or 3 h in a large number of tests, and records were taken of the number of mounts per test, serves per test, the ratio of mounts to

Responses in fertility after selenium supplementation of breeding ewes in northern New South Wales were examined. The treatment (5 mg selenium) was given orally as sodium selenite three weeks before joining, and responses were measured in terms of th

The effects of feral pigs on the lambing performance of Merinos was studied at Nyngan, New South Wales. Ewes lambed in two paddocks; one with feral pigs and one with no pigs in autumn and spring in 1978 and 1979. Ewes were pregnancy tested before lam
