Effects of substituting soya bean meal (SBM) with blood meal (BM) on biochemical profile of pregnant pigs.

Twenty-four Large White × Landrace crossbreed primigravid pigs, aged 7.50 to 8.00 months weighing between 86.

Disruption of spermatogenesis in boars sub-clinically infected with Trypanosoma brucei brucei.

Data from 14 crossbred (Landreace x Large white) boars aged 10-12 months were used to investigate specific germ cells and to what extent Sertoli cells are prone to sub-clinical infection with strain Y58/98 Trypanosome brucei brucei and effects on spermatogenesis. Boars were divided into three groups, A, B and C of 5, 5 and 4 animals, respectively. Groups A and B were infected intraperitoneally with 2.

Assessment of development of the testes and accessory glands by ultrasonography in bull calves and associated endocrine changes.

The testes, prostate and vesicular glands of 10 bull calves were examined by ultrasonography every 2 wk from 2 to 46 wk of age, at which time the scrotal circumference (SC) of all the calves had reached pubertal size (28 cms). Computer-assisted image intensity analysis (numerical pixel values) was conducted. Blood samples were collected every other week from 2 to 46 wk of age.

Ultrasonography of the developing reproductive tract in ram lambs: effects of a GnRH agonist.

In spring-born ram lambs, the testes (from 2 wk), prostate and vesicular glands (from 4 wk) were examined by ultrasonography every 2 wk up to 26 wk of age. Image analysis was done (numerical pixel values). Ram lambs were treated with a long acting formulation of a GnRH superagonist (Leuprolide acetate; 1.
