PENGARUH LEVEL PEMBERIAN KIO3 [GARAM BERJODIUM] TERHADAP AVERAGE DAILY OF GAIN PADA SAPI AUSTRALIAN BRAHMAN CROSS

Abstract

Materi penelitian menggunakan 12 ekor Australian Brahman Cross jantan umur 1-1,5 tahun [PI0 – PI1] berat badan rata-rata 340,60±14,04 kg, kemudian diacak kemedia percobaan. Rancangan percobaan menggunakan Randomized Block Design 4x3 dengan treatment A= 80% Elephant grass+20% rice straw; B= 80% Elephant grass+20% rice straw+50 gram garam berjodium [KIO3]; C=80% Elephant grass + 20% rice straw+100 gram garam berjodium dan D=80% Elephant grass+20% rice straw+150 gram garam berjodium. Dari hasil penelitian deketahui bahwa tingkat level pemberian garam berjodium tidak berpengaruh nyata [P0,05] terhadap average daily of gain dan konsumsi BK/hari pada semua treatment.Average daily of gain kelompok A= 0,71±0,11 kg; B= 0,82±0,03 kg; C= 0,70±0,20 dan D= 0,72±0,08 kg. Sedangkan rata-rata konsumsi BK/hr pada perlakuan A=10,34±0,08 kg; B=10,34±0,20 kg; C= 10,31±0,12 kg dan D = 10,45±0,30 kg. Hasil penelitian menyimpulkan bahwa penambahan tingkat level garam Jodium sampai pada tingkat 150 gr dalam ransum belum berpengaruh terhadap peningkatan Average daily of gain maupun konsumsi BK. Kata kunci : KIO3, Australian Brahman Cross The influence of KIO3 [Iodinated Salt] intake level to average daily Gain of Australian Brahman Cross Abstract The research employed 12 males Australian Brahman Cross age 2 [PI0 – PI1] with average daily gain of 340,60±14.04 kg and randomly placed into the media, Randomized Block Design 4x3 is used with treatment A= 80% Elephant grass+20% Elephant grass+20% rice straw+100 gram Iodinated Salt [KIO3] and D=80% Elephant grass+20% rice straw+150 gram Iodinated Salt. The result shows the level of iodinated salt intake gives no significance influence [P0.05] to average daily gain and BK/day consumption on all treatments. Average daily gain of group A= 0.71±0.11 kg; B = 0.82±0.03 kg; C= 0.70±0.20 and D= 0.72±0.08 kg. Whilst the average consumption of dry matter per day on treatment A=10.34±0.08 kg; B= 10.34±0.20 kg; C=10.31±0.12 kg and D= 10.45±0.30 kg. The result indicates the increase on iodinated salt intake level up to 150 gram infeed has no significance influence to the increase of average daily gain and dry matter consumption.
