Summary
Pregnant ewe nutrition significantly impacts offspring meat and wool production, and reproductive success. Understanding these effects is crucial for optimizing livestock performance through maternal dietary management.
Area of Science:
- Animal Science
- Reproductive Biology
- Nutritional Science
Background:
- Foetal programming in sheep influences growth, production, behavior, and immunity.
- Endocrine, metabolic, and epigenetic factors are key to offspring development.
- Parental nutrition before conception can induce lasting effects on offspring.
Purpose of the Study:
- To evaluate the impact of pregnant ewe nutrition on offspring performance.
- To assess effects on meat production, wool yield, and reproductive capabilities.
Main Methods:
- Focused on the direct effects of maternal nutrition during pregnancy.
- Examined foetal growth and subsequent productive traits in offspring.
Main Results:
- Maternal nutrition during gestation is a key determinant of offspring productivity.
- Specific nutritional strategies can enhance meat and wool production and reproductive outcomes.
Conclusions:
- Pregnant ewe nutrition plays a critical role in shaping offspring phenotype.
- Targeted nutritional interventions offer a pathway to improve livestock performance.

01:08Cloning of Dolly the Sheep
3.6K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

01:27Reproductive Cloning
30.3K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

01:22Imprinting
9.7K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

01:07Teratogenicity
2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
