A scoring system from 1 to 5 that categorizes calving difficulty, ranging from unassisted (1) to abnormal presentation (5).

Heterosis

Enhanced performance resulting from the mixing of genetic contributions from both parents.

Genotype vs Phenotype

Genotype refers to the genetic makeup (G) of an organism, while phenotype (P) is influenced by genotype and environmental factors (E).

Autosomal Recessive Diseases

Conditions that require two copies of a mutated allele to manifest; modern DNA testing can identify these diseases.

Overgrazing

Flight Zones in Cattle Behavior

Personal space and comfort zones of cattle that dictate how they react to handlers and movement.

Fescue Toxicity

Condition caused by grazing fescue that leads to health issues in cattle, requiring management to mitigate symptoms.

Weight of Colostrum for Newborn Calves

Calves should consume 5-6% of their body weight in colostrum within the first 6 hours for effective immunity.

Cattle Feedlots

Facilities where high-quality feeds are used to finish cattle before market, considering health, prices, and feed conversion.
