Sexual activity and body and testis growth in prepubertal ram lambs of Friesland, Chios, Karagouniki and Serres dairy sheep in Greece.
Sexual activity, body size and testis growth in the prepubertal period (120-210days of age) were studied in five male lambs of each of four dairy sheep breeds. Sexual responses developed earlier in Friesland than in Chios and Karagouniki and latest in Serres ram lambs. Friesland lambs expressed interest in females at 127days of age and 34kg live weight 18-36days younger and 3.4-6.3kg lighter th...
متن کاملProtein requirements of Chios sheep during maintenance.
The requirements of non-lactating non-pregnant ewes for digestible nitrogen for maintaining nitrogen or weight equilibrium were studied using soybean meal or urea as the sources of supplemental nitrogen. From the nitrogen balance data, assuming nitrogen losses of .05 g N/kg -73, the digestible nitrogen requirement for maintaining nitrogen equilibrium was. 195 -+ .0237 and .188 + .0099 g N/kg.73...

متن کاملCharacterization of the PRNP gene locus in Chios dairy sheep and its association with milk production and reproduction traits.
The objective of this study was to examine the prion protein gene locus (PRNP) in Chios sheep. PRNP is linked with scrapie resistance in small ruminants. Here, its impact on milk production (test-day and total lactation yield) and reproduction (age at first lambing, conception rate at first service, and prolificacy) was assessed. Genotyping at codons 136, 154 and 171 (classical scrapie) and 141...
