GENETICS AND BREEDING FOR DISEASE RESISTANCE OF LIVESTOCK - Importance of disease resistance

Oct 19, 2026

Upload by Eliana

Provides an overview of disease resistance in livestock, explaining why resistant animals are essential for optimum production, stable livelihoods, and reduced economic losses. Describes how conventional management through antibiotics and vaccination can drive antibiotic-resistant pathogens and limit vaccine effectiveness due to multietiology and mutating strains. Highlights infectious diseases’ impact on morbidity, mortality, fertility, and production losses, and illustrates livestock-specific examples such as Garole sheep with higher fecundity and improved resistance to multiple diseases and parasites.

FAQs

Why is disease resistance important for livestock production?

Disease resistance supports physical health and helps maintain optimal production and economic return. Without it, disease can lead to depressed production, morbidity, and sometimes mortality.

What limitations exist in conventional disease management like antibiotics and vaccination?

Sustained antibiotic use can lead to antibiotic-resistant pathogens. Vaccines may be ineffective against diverse and frequently mutating strains, and some diseases have many strains that reduce effectiveness.

Which livestock example illustrates improved disease resistance?

Garole sheep are noted as being less susceptible to disease and having high fecundity. They show better resistance to common small-ruminant diseases such as parasitic infestation and foot-and-mouth disease, and to parasites like Haemonchus contortus.
