Relationships between energy intake and productivity in hill sheep.
Nutrition of hill cattle and sheep '97 the hill sheep industry the transfer of hill land to other uses or the restriction of sheep farming is frequently advocated. Rarely does this take into account the opportunities for improvement which exist at the biological level or whether modifications to or changes in systems could make sheep production economically viable. Subsequent papers will presen...
متن کاملGenetic Analysis of Ewe Productivity Traits in Baluchi Sheep
The present study was carried out to estimate (co)variance components and genetic parameters for some productivity traits of Baluchi ewes. The data were collected during a 31 year period (1984-2014) at the experimental breeding station of Baluchi sheep, which is located in north-east of Mashhad, Iran. The analysis was based on 14030 records of lambs and 4371 records of ewes. Investigated traits...
متن کاملSire and liveweight affect feed intake and methane emissions of sheep confined in respiration chambers
Daily methane production and feed intake were measured on 160 adult ewes, which were the progeny of 20 sires and 3 sire types (Merino, dual-purpose and terminal) from a genetically diverse flock. All animals were housed in individual pens and fed a 50/50 mix of chaffed lucerne and oaten hays at 20 g/kg liveweight (LW), with feed refusals measured for at least 10 days before the first of three 2...
متن کاملProductivity-Diversity Relationships in Lake Plankton Communities
One of the most intriguing environmental gradients connected with variation in diversity is ecosystem productivity. The role of diversity in ecosystems is pivotal, because species richness can be both a cause and a consequence of primary production. However, the mechanisms behind the varying productivity-diversity relationships (PDR) remain poorly understood. Moreover, large-scale studies on PD...
متن کاملGenetic Relationships among Four Saudi Arabian Sheep Populations
Four Saudi Arabian indigenous sheep populations including Najdi, Hbsi, Arb, and Naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (FAO). This study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. All loci were polymorphic in all populations and loc...
