HUBUNGAN ANTARA KARAKTERISTIK SPERMA DALAM MANI BEKU DENGAN KEBERHASILAN INSEMINASI BUATAN PADA SAPI PERAH FRISSIAN HOLSTEIN
Full text linkThe objective of this research was to evaluate of the relationship between sperm characteristics of frozen semen to artificial insemination results. The measurement of artificial insemination results were non return rate (NR) and conception rate (CR). The measurement of sperm characteristics were progressive motility, sperm membrane intact and acrosome intact. The correlation of sperm progressive motility, sperm membrane plasm intact and sperm acrosome intact to NR were 0,198, 0,216 and 0,968 respectively. The correlation of sperm progressive motility, sperm membrane plasm intact and sperm acrosome intact to CR were 0,100, 0,194 and 0,917 respectively. Based on all data, the sperm acrosome intact was high correlation to artificial insemination results
SINBIOTIK ANTARA EKSTRAKS INULIN DARI BAWANG MERAH (Allium cepa) DENGANLactobacillus casei strain BIO 251 DAN UJI BIOAKTIVITASNYA TERHADAP BAKTERI PENYEBAB DIARE
Full text linkInulin is prebiotic polymers mainly comprising of fructose units in wich are bond by a β(2-1) glycosidic link and typically have a terminal glucose. Inulin can be extracted from natural source. At this research, inulin’s extraction from dahlia root produces yield of inulin 3.99% and onion (Allium cepa) with yield of inulin 0.2%. Extract of inulin from dahlia roots has 3.9% reduce sugar, 7.0% cold water solubility, 1:1.4 water binding capacity and result of TLC analysis shows retention time Rf 0.50. Extract of inulin from onion has 2.5% reduce sugar, 10.5% cold water solubility, 1:1.1 water binding capacity and result of TLC analysis shows Rf 0.49. Extract of inulin at concentration 437.8 ppm both inulin from dahlia root and onion are able to influent Lactobacillus casei strain Bio 251 there are 52.6% and 48.1%. Synbiotic that containing extract of inulin, both inulin from dahlia root and from onion with minimum concentration 434.8 ppm can be inhibited Salmonella thypi that is one of bacteria causes diarrhea which values 94.6% and 91.4%, respectively
