A descriptive study using 30 female local Lombok ducks age ready to lay was carried out to know the local Lombok egg duck production and its quality raised intensively in Centre Lombok for making a salted egg. The observation was done in three months. Variable observed were eggs production (monthly production, egg weight, egg index), shell quality (texture, thickness, color), and internal egg quality (yolk index, yolk color, yolk and albumen weight ratio, egg spot). Data were analyzed by using simple statistic to get the mean and the deviation standard. The observation results were: monthly egg production in the first three months were 58,15 ± 10,98%; 60,25 ± 10,60%; 50,00 ± 15,73%; average egg weight and its index were 61,42 ± 2,73 gram and 0,74 ± 0,10. The shell surface was smooth and the thickness was 0,40 ± 0,09 mm. The shell color was greenish dark blue. The yolk index was 0,47, the yolk color varied between 10 and 14, the yolk albumen ratio was 1.04, and there was not an egg spot. The quality of the local Lombok egg ducks was good for making a salted egg.

A potential production study of Sasak duck and the non-indigenous ducks (Campbell, mojosari, MA, and alabio ducks) was carried out in Centre Lombok Regency. Research materials were 50 female DODs for each breed. The variables observed were growth rate and feed conversion. The growth rate was measured every week from started from DOD until 10 weeks old. The data obtained were analyzed by using one-way ANOVA Complete Randomized Design. Results of research: body weight gain (BWG) for all breed increased until age between 5-6 weeks after that declined. Sasak and Campbell BWG were the least. The shank length average of all breed increased 253,86% within ten weeks. The shank length gain (SLG) for all breeds decreased steadily from the first week. The relative SLG of Sasak and MA ducks were between labia duck and Campbell ducks. The relative SLG of labor duck was highest and while that of mojosari ducks was the lowest. The average of the shank diameter gain within 10 weeks for all breeds increased 217.43%. There was no shank diameter difference (P 0.05 >) between Sasak ducks and the nation Lombok indigenous ducks. The average of middle finger length (MFL) of all breeds from one to 10 weeks increased 181,90%. The relative MFL gain of Sasak and Campbell ducks were less (P < 0.05) than that of the other three breeds. The feed conversion of Sasak, Campbell ducks, mojosari, MA, and alabio were 3.60; 3.90; 4.04; 4.06, and 3.66 consecutively.

Respon Tingkah Laku Birahi, Service Per Conception,Non Return Rate, Conception Rate pada Sapi Bali Dara dan Induk yang Disinkronisasi Birahi dengan Hormon Progesteron Mardiansyah Mardiansyah; Enny Yuliani; Sugeng Prasetyo

The aim of this study was to determine the differences ofestrous response, service per conception (S/C), nonreturn rate (NRR),and conceptionrate (CR) between Bali cattle heifersandcowssynchronized using intra-vaginalprogesterone hormone. Two groups of Bali cattle, 15 heifers and 15 cows, were used to examine the responsedifferences of estrous synchronization using progesterone hormone on reproductive performance, betweendifferent parity. Each group was given progesterone dose of 1 mg/kg body weight. The data observed wereestrousbehavior (estrousintensity, onset of estrous, estrous percentage), and value of S/C, NRR, and CR wereanalyzed by statistical analysis (t-test). The result shows the estrous intensity was significantly different (P<0.05)between the heifers and cows. The average estrousintensity score of the heifer was 2.87±0.35, while the cows was2.27±0.45. There was significantly different (P <0.05) in onset of estrous in the cows 41.5±5.18 hours, while inthe heifers was 50.67±3.5 hours. The estrouspercentage of the heifers and cows was the same, both of them was100%. There was no significant difference (P>0.05) in S/Cvalue showed by the heifers (1,31±0,45)and the cows(1,50±0,50). The average value of NRR, for heifers and cowswas 86.67% and 80.00%, respectively. The averagevalue of CRfor heifers and cowswas 86.67% and 80.00%, respectively.

Determination of the value of hardness, corrosion rate and microstructure after the quenching process with variations in immersion time with the help of ultrasonic waves, cooling media in 3,5% HCl solution. The specimens were placed in ultrasonic batches with a frequency of 45 KHz to obtain maximum results. the lowest hardness values in water cooling media occurred at the time of immersion using ultrasonic waves 7 hours, tempering temperatures of 300°C, 400°C and 500°C were 0,6 HRA, 51.2 HRA, 51,6HRA for oil medium of 40 ,3HRA, 41.2HRA, 41.3HRA. While the value of the corrosion rate was obtained the higher the tempering temperature and the length of immersion time the corrosion rate decreased the corrosion rate value in the oil cooling medium was 0.1663 mm/year, 0.1663 mm/year, 0.4726 mm/year, respectively. as well as water cooling media, respectively, namely 0.2125 mm/year, 0.3151mm/year and 0.2538 mm/year. metallographic test results can be a lot of pearly and ferrite formed.
