Feeding Value

Cilj rada bio je usporediti proizvodnost i hranidbenu vrijednost fermentirane krme dvaju hibrida sudanske trave s obzirom na prinos krme po jedinici površine te osnovni kemijski sastav i kvalitetu fermentacije krme u silosu. U istraživanju su korištene dvije sorte sudanske trave, sorta Su-Su i sorta Pacific graze. Istraživanje je provedeno tijekom vegetacijske sezone 2014. godine na pokusnoj površini pokušališta Maksimir Agronomskog fakulteta Sveučilišta u Zagrebu. Pokošena biljna masa je silirana u laboratorijske silose. Nakon 35 dana od zatvaranja silosa, fermentirana krma je analizirana NIR spektroskopijom na osnovni kemijski sastav i kvalitetu fermentacije, procjenom sadržaja organske tvari (OT), sirovih proteina (SP), neutralnih detergent vlakana (NDV), kiselih detergent vlakana (KDV), metaboličke energije (ME), probavljivosti organske tvari u suhoj tvari (D-vrijednost), razgradivosti sirovih proteina (RSP), faktora konzumacije za ovce i goveda, pH vrijednosti i amonijskog N (NH3-N). Nisu utvrđene statistički značajne razlike između hibrida Pacific graze i Su-su u istraživanim parametrima. Prinos ST hibrida Pacific graze i Su-su je iznosio 11,5 t ha-1 i 12,88 t ha-1 tim slijedom (P>0,409), sadržaj SP 102,3 g kg-1 ST i 103,8 g kg-1 ST tim slijedom (P>0,802), sadržaj NDV 507 g kg-1 ST i 514 g kg-1 ST tim slijedom(P>0.523), D-vrijednost 605 g kg-1 ST i 602 g kg-1 ST tim slijedom (P>0,341), pH vrijednost 4,26 i 4,4 tim slijedom (P>0,193), a sadržaj NH3-N 116 g NH3 kg-1 ukupnog N i 131 g NH3 kg-1 ukupnog N tim slijedom (P>0,254). Zaključeno je da oba hibrida sudanske trave imaju potencijal za proizvodnju fermentirane voluminozne krme visokog prinosa po jedinici površine, a niža hranidbena vrijednost fermentirane krme utvrđena u ovom istraživanju je rezultat kasnijeg roka košnje biljne mase za siliranje.

Cassava Residue

The feeding value of replacing concentrate with cassava (Manihot esculenta) residue in the feed of Holstein cows was confirmed using an in vitro gas test. The treatments consisted of 0% (control, CON), 5%, 10%, 15%, 20%, 25%, and 30% inclusion of cassava residue in fermentation culture medium composed of buffer solution (50 mL) and filtrated rumen fluid (25 mL). The parameters analyzed included the kinetics of gas production and fermentation indexes. Forty-eight hours later, there were no significant differences on in vitro dry matter disappearance (IVDMD), pH, and microbial crude protein (MCP) content among treatments (p > 0.05). However, the “cumulative gas production at 48 h” (GP48), the “asymptotic gas production” (A), and the “maximum gas production rate” (RmaxG) all increased linearly or quadratically (p < 0.01). The GP48 was significantly higher in the 25% treatment compared to the other treatments, except for the 30% (p < 0.01). The A was significantly larger in the 25% treatment compared to the other treatments, except for the 20% and 30% (p < 0.01). The RmaxG was distinctly larger in the 25% treatment compared to other treatments (p < 0.01); moreover, the “time at which RmaxG is reached” (TRmaxG) and the “time at which the maximum rate of substrate degradation is reached” (TRmaxS) were significantly higher in the 25% treatment than the CON, 20%, and 30% treatments (p < 0.01). Additionally, the content of ammonia-N (NH3-N) in all treatments showed linearly and quadratically decreases (p < 0.01), whereas total volatile fatty acid (VFA), iso-butyrate, butyrate, and iso-valerate contents changed quadratically (p = 0.02, p = 0.05, p = 0.01, and p = 0.02, respectively); all of these values peaked in the 25% treatment. In summary, the 25% treatment was associated with more in vitro gas and VFA production, indicating that this cassava residue inclusion level may be used to replace concentrate in the feed of Holstein cows. However, these results need to be verified in vivo.

SUMMARYExperiments made with winter fodder crops, lucerne (Medicago sativa), berseem (Trifolium alexandrinum) and oats (Avena sativa) and summer fodder crops, cow pea (Vigna unguiculata), guar (Cyamopsis tetragonoloba), sunhemp (Crotolaria juncea) and pearl millet (Pennisetum americanum) showed that a sequential crop of Sudan grass yielded more after the legumes than after the cereal fodders, oats or pearl millet. The legume advantage was noted in the crop not given fertilizers but also when Sudan grass was given N fertilizer. The yield increase in Sudan grass grown after legumes was equivalent to 32–60 kg fertilizer N/ha applied to Sudan grass following pearl millet.After harvesting the legumes more available N and NO3-N was present in the soil and the apparent recovery of fertilizer N by a subsequent crop was increased by the legume.
