摘要

Reliable forage preservation is critical for sustaining milk production in semi-arid dairy systems. However, evidence on the comparative efficiency of different silage storage methods and feeding levels remains limited. Maize silage preserved in trench, bunker, and bag silos was analyzed for (Table 1, fermentation quality, and digestibility. A 16-week feeding trial was conducted with crossbred dairy cows fed diets containing graded levels of silage (0%, 33%, 66%, and 100%). Milk yield, composition, body condition, lactation persistence, and profitability were evaluated. Bag silage retained higher crude protein (7.3%) and starch (13.6%), with lower fiber (3.6%), ammonia-N (8.4% of total N), and aflatoxin B₁ (7.6 ppb) than trench or bunker silages. Fermentation quality was superior, with lower pH (3.85) and higher lactic acid (6.4% DM). In vitro digestibility was also higher, with dry matter (72.4%) and NDF (58.6%) digestibility. Feeding trials showed that increasing silage inclusion significantly (p < 0.05) enhanced milk yield and composition. Cows fed 66% silage achieved the best performance, producing 13.9 L/day by week 16, with higher fat (4.5%) and protein (3.7%) contents. Economic analysis indicated that the 66% silage group achieved the highest net returns (10,980 PKR/cow/month).
