Effect of Bovine Somatotropin Administration on Day 11 after Artificial Insemination in Estrus-Induced Ewes during the Non-Breeding Season
Provedor de dados: 19

The present study aimed to examine the possibility that bovine somatotropin (BST) treatment after artificial insemination (AI) may improve the fertility by the stimulation of corpus luteum (CL) function in seasonally anestrous ewes. The experiment was conducted at the Tawa Field Station, Shibecha-cho in Hokkaido, Japan, during the non-breeding season (May, 1995). Eighty-nine mature (2 to 3 years old) Suffolk and Suffolk-crossed ewes were treated with controlled internal drug release devices containing 0.3 g progesterone (CIDR-G) for 12 days. Ewes were injected intramuscularly with 500 IU PMSG the day before CIDR removal. Eighty-seven ewes were assigned to an insemination of frozen semen on a fixed-time basis (42 to 50 h) after removal of CIDR. On the 11th...

Enhanced Oocyte Activation by Intracytoplasmic Injection of Porcine Spermatozoa Pre-treated with Dithiothreitol
Provedor de dados: 19
Autores: Watanabe, Hiroyuki; Akiyama, Junko; Bhuiyan, Mohammad Musharraf Uddin; Fukui, Yutaka; 福井, 豊.
The aim of this study was to confirm the effect of dithiothreitol (DTT)-treated spermatozoa on oocyte activation following intracytoplasmic sperm injection (ICSI). Boar spermatozoa with or without DTT treatment (5 mM, 30 min) were injected into in vitro matured porcine oocytes, and the nuclear phase in presumptive zygotes was observed at 3 h intervals up to 12 h after ICSI. Furthermore, developmental competence of embryos produced by DTT-treated or non-treated spermatozoa was monitored after cultivation in vitro for 144 h. Male and female pronuclear formation rates in the oocytes injected with DTT-treated spermatozoa were significantly (P &lt; 0.05) higher than those in the oocytes injected with non-treated spermatozoa. Additionally, we observed that...

Chemical characterization of the oligosaccharides in Bryde's whale (Balaenoptera edeni) and Sei whale (Balaenoptera borealis lesson) milk

Samples of milk from a Bryde's whale and a Sei whale contained 2.7 g/100 mL and 1.7 g/100 mL of hexose, respectively. Both contained lactose as the dominant saccharide along with small amounts of Neu5Ac(alpha 2-3)Gal(beta 1-4)Glc(3'-N-acetylneuraminyllactose), Neu5Ac(alpha 2-6)Gal(beta 1-4) Glc(6-N- acetylneuraminyllactose) and Neu5Ac(alpha 2-6)Gal(beta 1-4)GlcNAc(beta 1-3)Gal(beta 1-4)Glc (LST c). The dominance of lactose in the carbohydrate of these milks is similar to that of Minke whale milk and bottlenose dolphin colostrum, but the oligosaccharide patterns are different from those of these two species, illustrating the heterogeneity of milk oligosaccharides among the Cetacea.
