Abstract

Two corn hybrids (conventional: CON; silage: SIL) were harvested at early dent (ED), 72 milkline (72 ML), and black layer (BL) stages of maturity for testing the effects of hybrid, stage of maturity, and length of fermentation on corn silage quality. Tested parameters were pH, DM, CP, and ruminal in situ DM disappearance (ISDMD), respectively. Longer fermentation length caused lower silage pH at 8 (3.97) and 16 (3.93) weeks. While CP content tended to increase with longer fermentation length, it tended to decrease with increasing maturity stage (ED: 8.0%; BL: 7.2%). In situ DM disappearance was 4% higher for the SIL hybrid compared to CON hybrid (40.1% vs. 36.2%). Higher ISDMD was observed for ED (48.4%) and 72 ML (42.8%) maturity stages compared to the BL maturity stage (23.5%). In conclusion, similar chemical composition, but higher ISDMD favored the SIL hybrid over CON hybrid. Based on chemical composition and ISDMD, the optimum harvesting stage in whole plant corn silage should be between ED and 72 ML. In addition, for optimal pH, fermentation length should be between 8 and 16 weeks in whole plant corn silage.

Özet

İki farklı mısır silajı hibriti (Tane; T, Silajlık; S) erken sütlenme (ES), 72 sütlenme (72 S) ve siyah katman (SK) olgunluk derecelerinde hasat edilmiştir. Her bir hibrit ve olgunluk derecesindeki mısır silajları sırasıyla 0, 1,2, 4, 8, ve 16 haftalık sürelerde fermantasyona tabi tutulmuştur. Silaj kalite parametreleri sırasıyla pH, kuru madde (KM), ham protein (HP) ve ruminal in situ KM sindirilebilirliği olarak ölçülmüştür. Uzayan fermantasyon süresi optimum silaj pH değerini sağlamıştır (8 hafta = 3,97, 16 hafta = 3,93). Optimum silaj KM düzeyi her iki hibritte de ortalama olarak V2 S olgunluk derecesinde oluşmuştur (% 36,4). In situ KM sindirilebilirliği S hibritinde T hibritine göre % 4 daha yüksek gözlemlenmiştir. Mısır silajlarında, fermantasyon uzunluğu ile in situ KM sindirilebilirliği arasında bir ilişki gözlemlenmezken (r = 0,15), ES (% 48,4) ve 7Z S (% 42,8) olgunluk derecelerinde, SK (% 23,5) olgunluk derecesine göre daha yüksek ruminal in situ KM sindirilebilirliği gözlemlenmiştir. Optimum pH ve HP içerikleri mısır silajlarında en az 8 haftalık bir fermantasyon uzunluğunun olması gerektiğini göstermiştir. Kimyasal kompozisyon ve in situ KM sindirilebilirliği, optimum hasat olgunluğunun ES ve 72 S arasında olması gerektiğini göstermiştir.
