Impact of Booroola fecundity gene introgression on sheep production: Indian perspective

Indian Journal of Animal Sciences, 2021
Surge of demand for meat from diverse sources in a time of decling land and other natural resources shifted the trend of producing more sheep per sheep. Prolificacy aspect in sheep can be used as an important arsenal to fulfil this objective.

Breeding with resistant rams leads to rapid control of classical scrapie in affected sheep flocks [PDF]

, 2011
Susceptibility to scrapie, a transmissible spongiform encephalopathy in sheep, is modulated by the genetic make-up of the sheep. Scrapie control policies, based on selecting animals of resistant genotype for breeding, have recently been adopted by the ...

Gastrointestinal nematode species burdens and host mortality in a feral sheep population [PDF]

, 2006
Every few years a large proportion of the feral sheep on Hirta, St Kilda die due to food shortage. The effects of malnutrition are exacerbated by gastrointestinal nematodes. As found in sheep flocks in mainland Britain, Teladorsagia circumcincta has long

INFLUENCE OF THE PREGNANCY AT EARLY AGE ON THE REPRODUCTION AND PRODUCTION LIFE IN EWES OF THE BOTOSANI KARAKUL BREED

Scientific Papers Animal Science and Biotechnologies, 2023
The paper presents experimental results concerning the age importance of the first freshening of the ewes belonging to the Botosani Karakul breed. Some females were mated at an early age (8-9 months old) and others at the normal physiological age (16-18 ...

Chromatin accessibility and transcriptomic profiles of sheep pituitary function associated with fecundity

BMC Genomics
Background The pituitary gland, a central regulator of the hypothalamic-pituitary-gonadal (HPG) axis, plays a pivotal role in reproductive efficiency by precisely controlling the secretion of gonadotropins, including follicle-stimulating hormone (FSH ...

Improving sheep feedlot management [PDF]

, 2006
This paper summarise six studies undertaken by the Sheep CRC to elucidate certain aspects of confinement feeding of sheep. A review of confinement feeding highlighted the variability of growth rate and feed conversion of sheep and revealed that little is

Kinetics of the local cellular response in the gastric lymph of immune and susceptible sheep to infection with Teladorsagia circumcincta [PDF]

, 2009
Groups of yearling sheep were trickle infected with Teladorsagia circumcincta for 8 weeks, then the infection cleared with anthelmintic and both these animals and a group of parasite naïve sheep were challenged with 50 000 infective T.
