Mogensen L; Kristensen T

Abstract In Denmark, organic feeding is typically based on homegrown feed with a highproportion of roughage. Which crop to grow and use as supplementary feed is investigated in thispaper. In three experiments, barley (B) was compared with another type of supplementary feed: aconcentrate mixture (C), (more…)

Juras R; Cothran EG; Klimas R

Abstract This study was the first to analyze the polymorphic characteristics of a widerange of genetic markers in three Lithuanian horse breeds. Genetic variation at seven red bloodcell alloantigen (blood group) loci, 10 biochemical genetic loci and 16 microsatellites wasexaminated in 31 Zemaitukai, (more…)

Reproductive seasonality in sheep

Gundogan M; Baki D; Yeni D

Abstract Unlike most domestic livestock species, sheep are widely known as animalswith marked seasonality of breeding activity. The annual cycle of the daily photoperiod has beenidentified as the determinant factor of this phenomenon, while environmental temperature,nutritional status and social interactions may modulate it. The aim of this paper is to review thecurrent state of knowledge of reproductive seasonality in sheep. (more…)

Production results and technological meat quality for pigs in indoor andoutdoor rearing systems

March 11, 2008 By: admin Category: Agricultural and Biological Sciences, Life Sciences

Stern S; Heyer A; Andersson HK; Rydhmer L; Lundstrom K

Abstract The objective of the study was to compare production results andtechnological meat quality for pigs born outdoors and reared indoors or outdoors during the summerperiod. A total of 279 pigs was reared in a large pen on deep litter, or outdoors. Daily weight gainand lean meat percentage were higher for pigs outdoors than indoors during year one (864 vs. 841g;56.9 vs. 55.9%), (more…)

Analyses of possible domestic pig contribution in two populations of finnishfarmed wild boar

Abstract It is believed that some Finnish farmed “Wild Boars” may not originate fromgenuine European Wild Boar. To test this the D-loop mitochondrial sequence and nuclearglucosephosphate isomerase processed pseudogene (GPIP) and melanocortin receptor 1 (MC1R) genes wereanalysed in 41 Finnish farmed Wild Boar from two farms in order to determine if there was anyevidence of hybrid origins.
