Evaluation of Awassi sheep genotypes for growth, milk production and milk composition
We evaluated growth, milk production and composition of Awassi genotypes based on 9 years data collected from the International Center for Agricultural Research in the Dry Areas (ICARDA) flock kept in Tal Hadya station, ...
Biomass yield and feeding value of rye, triticale, and wheat straw produced under a dual-purpose management system
Dual-purpose management of winter cereals for grazing and grain production provides highly nutritive forage for ruminants in the spring and may positively affect straw feeding value. A 2-yr study investigated the effect ...
Supplementing Barbarine ewes every two days around mating does not hamper the reproductive performance in comparison to daily supplementation
Seventy Barbarine ewes were divided into two homogeneous groups and
received 1200 g/head/day of hay, supplemented with 400 g/head/day of concentrate, either daily (group C) or every two days (group A). The supplementation ...
Genomic footprints of dryland stress adaptation in Egyptian fattail sheep and their divergence from East African and western Asia cohorts
African indigenous sheep are classified as fat-tail, thin-tail and fat-rump hair sheep. The fat-tail are well adapted to dryland environments, but little is known on their genome profiles. We analyzed patterns of genomic ...
System dynamics modeling in designing breeding schemes: The case of Menz sheep in Ethiopian highlands
A comprehensive dynamic simulation model was developed to describe a community-based breeding program for the Menz sheep population of Ethiopia. Selection of male and female animals based on their own and maternal performance ...
Seasonal preference of Awassi sheep for Atriplex shrubs suitable for Mediterranean rangelands
The relative preference of Awassi sheep for four promising Atriplex species, A. halimus, A. nummularia, A. canescens and A. lentiformis was tested in cafeteria trials. Atriplex species were offered to sixteen sheep in ...
Molecular detection and phylogenetic analyses of Toxoplasma gondii from naturally infected sheep in Northern and Central Tunisia
Toxoplasmosis is a worldwide zoonosis caused by the parasitic protozoan Toxoplasma gondii. It can infect all warm-blooded vertebrate species and causes abortions and birth defects in pregnant women and pregnant ewes. The ...
FecXBar a Novel BMP15 mutation responsible for prolificacy and female sterility in Tunisian Barbarine Sheep
Background: Naturally occurring mutations in growth and differentiation factor 9 (GDF9) or bone morphogenetic
protein 15 (BMP15) genes are associated with increased ovulation rate (OR) and litter size (LS) but also ...
Effects of feeding different varieties of faba bean (Vicia faba L.) straws with concentrate supplement on feed intake, digestibility, body weight gain and carcass characteristics of Arsi-Bale sheep
Objective: A study was conducted to evaluate the varietal differences among faba bean straws
and also to assess the potentials of faba bean straws supplemented with concentrate fed at
the rate 70% straws and 30% concentrate ...
