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. |

Green manuring is an agronomic practice in which plants or their residues are added to the soil, improving of the soil physical, chemical and biological attributes, and increasing organic matter and fertility levels through nutrient cycling. It is estimated that green manures can increase P bioavailability. The integration of plant species in crop rotations to immobilize P is one of the most promising agronomic measures to improve the availability of P for the main crop. This study aimed to assess 21 species of green manure and a standard plant species (Lupinus albus) on their ability to absorb the available forms of P by the 32P isotopic dilution technique. It also aimed to determine if the isotopically exchangeable P, the L-values, differed when calculated with or without taking seed N into account. The results were statistically correlated and analyzed by hierarchical clustering (HCA) in order to group similar plant species. Jack bean was the most efficient species in P utilization while the Stylosanthes spp. were the most efficient in P uptake. The seed-derived P affected the P uptake efficiency evaluated by L-value technique. |
