A breeding soundness examination (BSE) involving animal physical examination, scrotal circumference (SC) and semen evaluation was undertaken on 80 Ile-de-France rams at a government breeding farm, 32 km south-west of Casablanca (Morocco) from March to May 1988. A large percentage of rams (21.4 pe...

This study was undertaken using 48 mature Menz ewes (3-6 years of age) and averaging 31.5 (standard deviation (SD)=4.9) kg body weight, to evaluate oestrus synchronization, conception and lambing rates after ram introduction following a period of isolation (n=24) or constant exposure to vasectomi...

Reproductive responses associated with ram introduction in mature tropical Menz ewes after a period of isolation
Abattoir, on-farm and market surveys revealed that 30 percent of the Menz rams were unfit for efficient breeding due to sexual disorders, mainly in the form of balanoposthitis, epididymitis and orchitis. On-station study of testicular size in adult rams, semen traits and libido showed that the te...

A study was conducted to estimate heritabilities of, and genetic correlations among, body weight (WT) and testicular measurements - scrotal circumference (SC), testicular diameter (TD), testicular length (TL) and epididymal diameter (ED - in ram lambs between 6, 9 and 12 months old, and relations...

A study was conducted to investigate the effect of season on, and to estimate heritabilities of, and genetic correlations among, semen and spermatozoa characteristics and the relationship of these characteristics with measures of testicular or scrotal size in 6-, 9- and 12-month old ram lambs of ...

Clinical examination, bodily condition score (BCS), heart girth (HG), body length (BL), wither height (WH), and scrotal circumference (SC) were assessed on 486 mature Ethiopian Menz rams, on small farms, in local markets, and at the main abattoir in Addis Ababa from December 1994 to April 1995.

The effect of urea-molasses feed-supplement blocks (MUB) on feed utilisation and the inclusion of anthelmintic medication into the blocks at strategic times to control nematode parasites was studied in lambs grazed on low quality tropical pasture. 120 Menz ram lambs of 5-7 months of age were divi...
