Effects of sire genotype on lamb performance at weaning in extensive sheep systems

open access: yesAnimal, 2019
A low finishing weight and poor carcass characteristics are major causes of lower incomes in extensive sheep flocks; however, the use of terminal sire crossbreeding would improve lamb performance and carcass traits under these conditions. The aim of this

Effects of glycerol supplementation to Awassi lambs diet on performance and carcass quality characteristics

open access: yesTikrit Journal for Agricultural Sciences, 2023
This experiment was conducted to explore the efficacy of glycerol on growth performance and carcass quality characteristics in Awassi lambs. Twelve Awassi lambs were used with an average body weight of 24.43 ±0.43 kg.  The animals were randomly assigned

A differential interplay between the expression of Th1/Th2/Treg related cytokine genes in Teladorsagia circumcincta infected DRB1*1101 carrier lambs [PDF]

open access: yes, 2011
peer-reviewedSubstantial debate exists on whether the immune response between sheep resistant and susceptible to gastrointestinal nematodes can be differentiated into a Th1 and Th2 phenotype.

Comparison of different growth curve models in romanov lambs [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2020
This study investigates the modelling of the individual growth curves of Romanov lambs using different equations and the data on the increase in live weight and selects the best model. For this purpose, the live weights of Romanov lambs that were brought

The dynamic influence of the DRB1*1101 allele on the resistance of sheep to experimental Teladorsagia circumcincta infection [PDF]

open access: yes, 2011
Suffolk sheep carrying the DRB1*1101 (previously referred to as-DRB1*0203 or G2) allele have been reported to show increased resistance to natural Teladorsagia circumcincta infection compared to non-carriers.

Differential expression of pattern recognition receptors during the development of foetal sheep [PDF]

open access: yes, 2008
Pattern recognition receptors (PRRs) play a crucial role in the initiation of the adaptive immune response. Immunological competence of foetal lambs occurs progressively throughout gestation, and in order to understand the role played by PRRs in foetal ...

Metazoan-protozoan parasite co-infections and host body weight in St Kilda Soay sheep [PDF]

open access: yes, 2008
For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation.

The role of lambs in louping-ill virus amplification [PDF]

open access: yes, 2000
In some areas of Scotland, the prevalence of louping-ill virus has not decreased despite the vaccination of replacement ewes for over 30 years. The role of unvaccinated lambs in viral persistence was examined through a combination of an empirical study ...

Interactions between groundwater and surface water at river banks and the confluence of rivers [PDF]

open access: yes, 2004
Riparian vegetation depends on hydrological resources and has to adapt to changes in water levels and soil moisture conditions. The origin and mixing of water in the streamside corridor were studied in detail.
