Aims We examine the average performance of Border Leicester (BL) flocks that are part of LAMBPLAN, Australia’s sheep performance recording and genetic evaluation system. We also summarise outcomes from the New South Wales Department of Primary Indu

Over 3 years, we examined the possible benefits of moving the joining date from mid March to early February for the productivity of a prime lamb system based on Border Leicester x Merino ewes on the southern tablelands of New South Wales. The proport

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

The mating performances of 15 rams which were initially sexually inactive were examined by allowing them constant exposure to three oestrous ewes per day. Two rams did not mount or serve any ewes in 17 days of exposure. When the 13 remaining rams beg

Mature Merino rams were joined at rates of one ram to 100 ewes (1.0%), one ram to 200 ewes (0.5%) and one ram to 400 ewes (0.25%) in paddocks at Richmond, New South Wales. Fresh rams were introduced each day of joining and mating activity was measure

Two groups of five medium Wool Peppin Merino rams were individually penned in an animal house for 18 months. During this time the normal seasonal pattern of changes in day length was reversed for one group of rams (treatment). The control group of ra

Three experiments were done to establish whether differences in ram fertility could explain some of the differences in reproductive performance observed between two flocks of Merino sheep, one flock of which had been bred for a high (Folds Plus) and

Merino rams selected for (Folds Plus) and against (Folds Minus) skin wrinkle have been used in a study of scrotal heat tolerance. The type selected against skin wrinkle (Folds Minus) showed a higher scrotal fluid loss and sweat gland and fibre densit

Variation in the fertility of Merino rams whose scrota and testes were heated in a chamber enclosing the scrotum was found to be mainly due to variation in the amount of heat reaching the testes. Variation in fertility due to variation in the respons

In Merino rams, subcutaneous temperature in the scrotum declined from the inguinal border to the distal tip and from posterior to anterior. Testicular temperature was similar at several sites in both testes. Of the total increase in scrotal and testi
