Abstract: The fertilizing capacity of goat semen stored at 5oC was evaluated in Cape Verdean goats. The semen was collected from three Canarian bucks and was diluted in Tris-egg yolk 2.5% extender to yield a final concentration of 150x106 mobile spermatozoa per 0.25 mL straw. The straws were inserted into a container and were maintained at 5oC for 24 (T24) or 48 hours (T48). A total of 133 goats were randomly assigned to receive one type of cooled semen. Estrus was synchronized with intravaginal sponges containing 60 mg of MAP for six days, plus 37.5 µg of d-cloprostenol and 200 IU of eCG, both of which were injected 24 h before sponge removal. Motility, strength, and HOST-reacted spermatozoa were recorded after cooling, according to treatment. Timed artificial insemination was performed at approximately 37 hours after sponge removal. Seminal motility (58.8±11.1 and 51.3±2.5%) and strength (2.9±0.5 and 2.8±0.3) did not differ (P>0.05) between the T24 and T48 samples. Swelled spermatozoa were superior (P<0.001) at T24 (63.5±19.7%) compared to T48 (31.2±22.1%). The pregnancy rates were similar (P>0.05) at T24 (26.5%) and T48 (21.5%). Goat semen maintains acceptable quality after cooling at 5ºC for 24 and 48 hours and can be used in artificial insemination programs in Cape Verde goats. Certain adjustments, including the time of artificial insemination relative to sponge removal, must be made to achieve better pregnancy rates. |

The physiological and morphological responses of the forage grasses Brachiaria brizantha cv. Marandu, B. decumbens and B. humidicola were compared for plants grown in pots under flooding and well-drained conditions for 14 days. Flooding reduced specific leaf area and biomass allocation to roots in all species and enhanced leaf senescence in B. brizantha and B. decumbens. Relative growth rate was reduced by flooding in B. brizantha and B. decumbens, but not in B. humidicola. Leaf elongation rate was unaffected by flooding in B. decumbens and B, humidicola, but declined in B. brizantha since the first day of flooding. Net photosynthesis and leaf chlorophyll content were reduced by flooding in B, brizantha; however, no flooding effect could be detected in the other two species. For all species, there was a close relationship between net photosynthesis and stomatal conductance under flooding. These results show that the studied species have distinct degrees of tolerance to flood, B. brizantha is intolerant, B. decumbens is moderately tolerant and B. humidicola is tolerant. Because leaf elongation rate was immediately depressed by flooding only in B. brizantha, this measurement could be appropriate as an early detection mechanism for relative flood tolerance in Brachiaria spp. |
