What These Numbers Mean for Your Herd
Bull proofs compare a sire's daughters against the breed average — here is what ABS MOONGLOW-ET's figures mean in practice:
PTA Milk +959 kg
His daughters are expected to give about 959 kg more milk per lactation than the average Holstein — roughly 3.1 extra litres every day for 10 months.
PTA Fat & Protein
Extra kilograms of butterfat and protein in his daughters' milk. Richer milk fetches better prices from processors who pay on solids, and makes more value per litre at the collection centre.
Somatic Cell Score 3.08
Lower is better. This is around breed average — daughters will need your normal milking hygiene to stay mastitis-free.
Productive Life +2
His daughters are expected to stay milking in your herd about 2.0 months longer than average — fewer forced replacements, more lifetime milk per cow.
Daughter Fertility -1.4
Slightly negative — his daughters may take a little longer to get back in calf. Sharp heat detection and good body condition after calving will matter more with this bull's daughters.
TPI 2,685
A single overall ranking combining production, health and type. Useful for comparing Holstein bulls side by side — above ~2,800 is elite in current rankings.
Beta Casein A1/A2
His daughters may carry a mix of A1 and A2 milk genetics.
Kenya-Relevant Ratings (1–5)
Our simplified scores for the traits that matter most on Kenyan farms. 5 is excellent, 3 is average, 1 is weak. The smart strategy: pick a bull whose strong ratings match your herd's weaknesses — if mastitis is your problem, prioritise Mastitis Resistance over Milk.
