Abstract

Experiment aimed to know daily gain cow for a month pre partus, birth weight, level of estrogen on 3 days pre partus, first estrus post partus, level of estrogen while estrus and estrus quality on dairy cow after fed by different quality of diets and infusion iodium. Povidon 1% solution intra uterine. This experiment was held on August 2002 to February 2003 in Samirono Village, Getasan Subdistrict, Semarang District. The materials of experiment that used are: 1). 18 Friesian Holstein dairy cows were old pregnant, dry period, awaiting for second lactation, body weight between 350-450 kg and in good condition. 2) feeds that used are concentrate that dairyman usually gave, concentrate from BPTP Central Java and Napier Grass. Experiment, design that used is Factorial Random Sampling Design. Treatment that done are : TO (6 cows): 6 cows received diets with crude protein (CP) 12 %, Total Digestible Nutrient (TDN) 65%, 3 cows received iodium povidon I % and 3 cows weren't receive; TI (6 cows): 6 cows received diets with crude protein (CP) 14 %, Total Digestible Nutrient (TDN) 70%, 3 cows received iodium povidon I % and 3 cows weren't receive; T2 (6 cows): 6 cows received diets with crude protein (CP) 16 %, Total Digestible Nutrient (TDN) 75%, 3 cows received iodium povidon I % and 3 cows weren't receive. Parameter that evaluated include: 1) Dry matter (DM) intake for Pre partus, 2) daily gain cow for a month pre partus, 3) birth weight 4) uterus mass, 5) level of estrogen on 3 days pre partus, 6) DM intake for 3 month postpartus, 7) level of estrogen on 42 and 63 days post partus, 8) first estrus post partus, 9) level of esrogen while estrus 10) feming of cervix liquid, 11) swallen of labia vulva, 12) vagina temperature, 13) pH servix. Liquid, 14), liquid overflow 15) color of mucosa vagina. Result of experiment saw that average of. A) daily gain cow for a month prepartus TO, TI and T2 0,669; 1,089; 1,167 kg (P<0,01); b) birth weight TO, TI and T2 30,08; 35,88; 38,18 kg (P<0,01); c) level of estrogen on 3 days pre partus TO, TI and T2 237,63; 416,48; 428,62 pg/ml (P<0,01); d ) first estrus post partus TO, TI and T2 132,5; 82; 68,5 days (P<0,01); e) level of estrogen while estrus TO, TI and T2 5,93; 10,52; 11,10 pg/ml; f) feming of cervix liquid TO, TI and T2 138,33; 225,83; 239,2 (P<0,01); g) pH cervix liquid TO, TI and T2 7,5; 7,67; 8,33 (P<0,01). Penelitian bertujuan untuk mengetahui pertambahan bobot badan harian (PBBH) induk selama 1 bulan pre partus, bobot lahir pedet, kadar estrogen 3 hari pre partus, estrus pertama post partus, kadar estrogen saat estrus dan kualitas estrus pada sapi perah yang memperoleh kualitas ransum berbeda dan infusi larutan iodium povidon 1 % intra uterin. Penelitian dilaksanakan pada bulan Agustus 2002 sampai Februari 2003 di Mesa Samirono, Kecamatan Getasan, Kabupaten Semarang. Materi yang digunakan adalah : 1) 18 ekor sapi perah, bunting tua, periode kering kandang, menjelang laktasi ke 2, bobot badan berkisar 350-450 kg, sehat. 2) Pakan yang diberikan berupa konsentrat menurut kebiasaan petemak dan fonnulasi BPTP Jawa Tengah serta rumput gajah. Rancangan percobaan adalah Rancangan Acak Lengkap (RAL) Faktorial. Perlakuan yang diterapkan adalah : TO (sapi 6 ekor) : diberi ransum protein kasar (PK) 12 %, Total Digestible Nutrients (TDN) 65%, 3 ekor diberi larutan iodium povidon 1% dan 3 ekor tidak diberi larutan iodium povidon 1%; T1 (sapi 6 ekor) : diberi ransum PK 14%, TDN 70%, 3 ekor diberi larutan iodium povidon 1% dan 3 ekor tidak diberi larutan iodium povidon 1%; T2 (sapi 6 ekor) diberi ransum PK 16%, TDN 75, 3 ekor diberi larutan iodium povidon 1% dan 3 ekor tidak diberi larutan iodium povidon 1%. Parameter yang diamati meliputi : (1) konsumsi bahan kering ransum selama 1 bulan prepartus, (2) pertambahan bobot badan harian induk selama 30 hari prepartus, (3) bobot lahir pedet, (4) massa uterus, (5) kadar estrogen 3 hari prepartus, (6) konsumsi bahan kering selama 3 bulan post partus, (7) kadar estrogen 42 & 63 hari post partus, (8) estrus pertama post partus, (9) kadar estrogen saat estrus, (10) ferning lendir servik, (11) kebengkakan labia vulva, (12) suhu vagina, (13) pH lendir servik (14) kelimpahan lendir dan (15) warna mucosa vagina. Hasil penelitian menunjukkan rata-rata a) pertambahan bobot badan harian induk selama 1 bulan prepartus TO, T1 dan T2 masing-masing 0,669 ; 1,089 dan 1,167 kg/hari (P<0.01); b) bobot lahir pedet TO, T1 dan T2 masing-masing 30,08 ; 35,88 ; 38,18 kg (P<0,01); c) kadar estrogen 3 hari prepartus TO, T1 dan T2 masing¬masing 237,63 ; 416,48 ; 428,62 pg/ml (P<0,01); d) estrus pertama post partus TO, T1 dan T2 karena pengaruh ransum masing-masing 132,50 ; 82,00 ; 68,50 hari (P<0,01), karena pengaruh povidon dan tidak povidon masing-masing 87,56 ; 101,11 hari (P<0,01); e) kadar estrogen saat estrus TO, T1 dan T2 masing-masing 5,93 ; 10,52 ; 11,10 pg/ml (P<0,01); 0 ferning lendir servik TO, T1 dan T2 masing-masing 138,33 ; 225,83 ; 239,20 (P<0,01)
