AbstractThis research was aimed to determine the measurement of male and famale Krui cattles in west Pesisir district Lampung Province. This research was conducted in November up to December 2016. The samples that observed were about 55 male cattles and 71 female cattles. The survey method was In this research, and those samples were determined by using purposive sampling. Data Were analyzed by t test. The observed variables include body weight, chest circumference, body length, and shoulder height. The results showed that the average body weight of male and female Krui permanent teeth of 0 the average shoulder level is permanent teeth of 0 pair (91.3 ± 86.7 cm), permanent teeth of 1 pairs (102,5 ± 97.8 cm), permanent teeth of 2 pairs (105.1 ± 101.1 cm), permanent teeth of 3 pairs (113 ± 104.7 cm). The results of this research show that body weight, chest circumference, body length, high shoulders of male and famale Krui cattles in the same age group showed significant difference (P<0,05).
<p class="Default">Saburai goat was crossing breed by grading up between male Boer and female Ettawah grade goat. This research was conducted to compare production performance of male Saburai goat at Gisting subdistrict and Sumberejo subdistrict as Saburai goat breeding source area. Survey method were used in this research by observation to 90 at Gisting subdistrict and 90 at Sumberejo subdistrict tails male Saburai goat as sample. The sample were choosed by purposive sampling method. Variables observed were birth weight (BW), weaning weight (WW), yearling weight (YW), average of preweaning daily gain (APreDG), average of postweaning daily gain (APostDG). The data was analyzed by t-student test. Result of research indicated that BW (3,42+0,28 kg), WW (16,22+3,77 kg), YW (36,56+4,85 kg), APreDG (140,00+0,04 g/tail/day), APostDG (70,00+0,02 g/tail/day) of Saburai goat at Gisting subdistrict was not different (P>0,05) with Saburai goat at Sumberejo subdistrict (BW 3,48+0,41 kg, WW 16,85+258 kg, YW 38,30+5,35 kg, APreDG 150,00+0,03 g/tail/day, APostDG 80,00+0,02 g/tail/day).</p><p class="Default"> </p><p>Keywords: performance production, Saburai male goat, Tanggamus</p>
The growth curve is a figure of an individual's ability to display of the body's genetic potential and development of the body. Research on the growth curve models of Saburai goat from birth until the age of 3 months has been implemented in the area of Tanggamus. The purpose of this study was to determine the growth curve models Saburai goat in pre-weaning period. This study used observation method with a random sample of 145 goats. Data were analyzed regression. The result showed that the growth curve models of Saburai goat from birth to 3 months followed the model of equation regression,Y= 0.16x + 3.29 for male and Y=0.149x + 3.25 for female.Key words: growth curve, Saburai goat, Tanggamus district ABSTRAK Kurva pertumbuhan merupakan gambaran kemampuan individu untuk menampilkan potensi genetik dan perkembangan tubuh mencapai dewasa. Penelitian mengenai model kurva pertumbuhan kambing Saburai sejak lahir sampai umur 3 bulan telah dilaksanakan di wilayah sumber bibit Kabupaten Tanggamus. Tujuan penelitian ini adalah untuk mengetahui model kurva pertumbuhan kambing Saburai pada periode pra sapih. Penelitian ini menggunakan metode observasi dengan sample acak sebanyak 145 ekor kambing. Data yang diperoleh dianalisis regresi. Hasil analisis menunjukkan bahwa model kurva pertumbuhan kambing Saburai dari lahir sampai 3 bulan mengikuti model persamaan regresi Y=0,16x + 3,29 untuk anak kambing saburai jantan dan Y=0,149x + 3,25 untuk betina.
Livestock is a source of animal protein that contains essential acids that improve human intelligence and health. Popular livestock in Indonesia is cow. Consumption of meat per capita is increased by 0.1% kg / capita / year. The high demand for beef in Indonesia is due to the increasing of population in Indonesia by 1.49% per year. More than 90% of cows are reared by rural communities with less of knowledge about livestock and have low economic capabilities. In addition, the number of experts or veterinarians are also limited. One of the solutions that can be done to socialize the knowledge of experts or veterinarians is by using expert system. Some methods that can be used in expert systems are Bayesian network and Dempster-Shafer method. The purpose of this research is to analyze the comparison of cow disease diagnosis with bayesian network and Dempster-Shafer method. In order to know which method is better in diagnosing cow disease. The data used is 21 cow diseases with 77 symptoms. Each method is tested with the same 10 cases. The conclusions obtained by Bayesian network and Dempster-Shafer method. Both of methods give the same diagnosis results but with different percentage. The mean value of diagnosis percentage by Dempster-Shafer method is 87,2% while bayesian network method is 75,3%. Thus, it can be said that the Dempster-Shafer method is better at diagnosing cow disease.
This research aimed to compare the growth performance of Ongole Grade (PO) cattle in Purwodadi Dalam and Wawasan villages. This research was conducted from December 2019 to January 2020 at the People's Animal Husbandry Center, Wawasan Village and Purwodadi Dalam Village, Tanjungsari District, South Lampung Regency, Lampung Province. This study used a survey method (purposive sampling), using primary and secondary data. The observed variables were birth weight, weaning weight and yearling weight. The results showed that the average weight gain of PO cattle in the village of Wawasan was 84.33 � 19.18 kg / head, which was higher than that of Purwodadi Dalam, namely 80.17 � 19.49 kg / head. The body weight gain after weaning of PO cattle in Wawasan Village was 39.15 � 21.34 kg, higher than that in Purwodadi Dalam Village, namely 37.75 � 21.10 kg / head. The body weight gain from birth to one year of PO cattle in Wawasan Village was 123.49 � 26.26 kg / head, which was also higher than that in Purwodadi Dalam Village, namely 117.93 � 30.50 kg / head. The results also showed that the corrected weaning weight of PO cattle in Wawasan Village (122.40 � 23.20 kg / head) was higher than that in Purwodadi Dalam Village (121.24 � 22.86 kg / head), and the average body weight of one year old of PO cattle in Wawasan Village was 147.95 � 26.58 kg / head higher than that in Purwodadi Dalam Village with an average weight of 141.98 � 31.37 kg / head. The results of the current study concluded that the growth performance of PO cattle in Wawasan Village was better than those in Purwodadi Dalam Village.
