The effects of photoperiod (8 hr light: 16 hr dark [8L:16D] or 16L:8D) on performance of growing-finishing lambs were evaluated in an experiment with 24 rams and 24 wethers. All lambs were caged in groups of two in a controlled environment and fed a pelleted diet ad libitum for the duration of the study (10 to 22 weeks of age). Performance and carcass data showed that both photoperiod and sex o...

Feeding and postruminal infusion of propionate is known to increase N retention in ruminants. Our aim was to determine the role of rumen propionate on urea N recycling and gluconeogenesis in growing sheep. In Exp. 1, wether sheep ( = 6; 32.5 ± 3.57 kg BW) fitted with a rumen cannula were fed to 1.8 × ME requirement a concentrate-type ration (172 g CP/kg DM and 10.4 MJ ME/kg DM) and continuously...

Lambs with the myostatin (MSTN) g+6723G>A mutation have a greater muscle mass, which is believed to be associated with reduced myostatin protein abundance. This experiment was designed to determine if differences in allelic frequency of the MSTN g+6723G>A mutation affected abundance of myostatin protein from birth to 24 wk of age. A Poll Dorset cross White Suffolk ram (MSTN A/G) was mated to 35...

Greater production demands for ruminants require increased dietary inclusion of high-energy feeds. Grains and oil seeds are most commonly used to enhance diet energy density. However, use of such feeds proportionally increases the amount of dietary phytate phosphorus (P), which the ruminant may not be able to fully utilise. Our objectives for this study were to determine the extent of phytate d...

The automatic extraction of the notes that were played in a digital musical signal (automatic music transcription) is an open problem. A number of techniques have been applied to solve it without concluding results. This work tries to pose it through the identification of the spectral pattern of a given instrument in the signal spectrogram using time-delay neural networks. We will work in the m...

The M100 wave representing a robust component of cortical Auditory Evoked Magnetic Fields (AEFs) is used to localize neuronal activation in the primary auditory cortex for a long time in neurophysiological research and with increasing importance also in clinical research [1-4]. Changes of location, orientation and strenght of equivalent current dipoles (ECD) are considered being correlated to c...

The Statute of Budva dates from the time of Nemanjics. This medieval document was approved at the time Budva was under venetian dominion and remained in force until the end of the Venetian Republic. During 17th century the Statute was translated into the Italian language. The document includes regulations which indicate a concern for the health of the public. Among the regulations is one which ...
