Helianthus Tuberosus L. Silage Quality and Usage Potential in Cattle Feeding

Abstract

Ensiling of Helianthus tuberosus L. was carried out in three terms/trials (15.8.2013 , 17.9.2013 and 7.10.2013). In the first trial Helianthus tuberosus L was ensiled in horizontal concrete silo trench, and in the second and third trial in a polyethylene foil. In the first and second trial dry matter content in Helianthus tuberosus L silage was 26.93:33.68%. Evaluated by DLG method silage trials had 41 and 44 points, and classified as class I or II, respectively. Silage pH values were 4.06:4.20. Content of lactic acid was 51.07:57.01%, total acetic acid 42.99:48.93%, withaut the presence of butyric acid. Consumption of silage in categories of heifers, beef cattle and dried milking cows was cca 3 kg. Better silage consumption was found in cattle categories fed a limited quantity of meals (heifers and dried milkingcows).

Siliranje čičoke (Helianthus tuberosus L.) je obavljeno u tri roka (15.8.2013, 17.9.2013 i 7.10. 2013. U prvom roku čičoka je silirana je u horizontalnom betonskom silosu a u drugom i trećem u polietilenskoj foliji u obliku creva. U prvom i drugom roku siliranja suva materija silaže čičoke iznosila je 26,93 : 33,68%. Ocenom po DLG metodu silaže su imale 41 odnosno 44 poena i svrstane u I odnosno II klasu. Vrednost pH silaža iznosio je 4,06 : 4,20. Sadržaj mlečne kiseline iznosio je 51,07 : 57,01%, ukupne sirćetne kiseline 42,99 : 48,93 % dok prisustvo buterne kiseline nije utvrđeno. Konzumiranje silaže čičoke kod priplodnog podlatka goveda, junadi u tovu i zasušenih krava iznosilo je oko 3 kg u obrocima na bazi silaže biljke kukuruza, sena lucerke i koncentrata. Bolje konzumiranje silaže čičoke utvrđeno je kod goveda hranjenih ograničenim količinama obroka (podmladak i zasušene krave).
