HERITABILITAS BOBOT TELUR, BOBOT TETAS DAN BOBOT BADAN AYAM HASIL PERSILANGAN UMUR 1 MINGGU (DOC) | | Author : septyanti Masili, safriyanto Dako, Fahrul Ilham, Syukri I. Gubali | | Abstract | Full Text | Abstract :The aim was to determine the heritability of egg weight, hatch weight, age of a week body weight in crossbred chickens. This research was conducted from August-November 2017, in Tumbihe Village, Kabila District, Bone Bolango District, Gorontalo province. The research material was eggs and DOC originating from a cross between male Kampung chicken and female Leghorn chicken, Isa Brown strain, these eggs were weighed and hatched in a hatchery machine. The parameters measured were egg weight heritability, hatch weight, 1 week body weight in crossbred chickens. Data were analyzed by descriptive statistics. The results of this study are the heritability of egg weight in the population is 0.533 ± 0.03 and the variance coefficient is 6.16%. The heritability of hatch weight in the population is 0.532 ± 0.02 and the variance coefficient is 4.33%. While the heritability value of 1 week age weight in the population is 0.530 ± 0.02 and the variance coefficient is 3.26%. |
| DETEKSI DINI KEBUNTINGAN PADA SAPI BALI MENGGUNAKAN ASAM SULFAT (H2SO4) | | Author : Suparmin Fathan, Fahrul Ilham, Indah Isnwaty | | Abstract | Full Text | Abstract :The purpose of this study was to determine the appropriate dosage, time and method of diagnosing pregnancy in Balinese cattle using a mixture of urine and aquadest which was reacted with Sulfuric Acid (H2SO4). This research was conducted in February - March 2018 in Bongo village, Wonosari sub-district, Boalemo Regency, Gorontalo Province. The material used is urine urine samples, which have been artificially inseminated. Concentrated sulfuric acid (H2SO4) of 0.3 ml, 0.5 ml, 0.7 ml, 0.9 and 0.11 ml (according to treatment). The variables observed were fluorescence gas in solution, change in color of solution, time of change in solution. Data were analyzed using unidirectional variance analysis. The results showed pregnancy detection in Balinese cows who had been on IB in each treatment gave a very significant effect (P <0.01. The results of the BNT test revealed that the age of 6 days had the fastest time in detecting pregnancy with ± 6 seconds, at age 11 and 16 days have the fastest time in detecting pregnancy, with an average time of ± 5 seconds the pregnancy can be detected. |
