Objective from this research was to determine the relationship of udder morphometry which consists of the height of the front udder, the height of the rear udder and the circumference ofudder on milk production in the Bima District of West Nusa Tenggara. One of ways to choose a good lactational mare is to pay attention at the shape of the part external body which is udder. The sample had used 32 mares that were in lactation period. Milk production has been measured from the average milk production per day in the lactation period. Milking process in Bima District, West Nusa Tenggara has done in three to four times a day in the span of four to five hours per day. Body length had been measured from os thoracalis to os coxae, chest circumference had been measured from os vertebrae thoracalis to os thoracalis, posterior abdomen of pelvic to os pelvis and the last of os lumbar vetebrae. The research design in this study was survey on every wild mares rancher. Data that has been collected and processed using Multiple Regression with SPSS program version 23th. The result showed that there was a strong relationship between height of rear udder and udder circumference to milk production with back udder with height coefficient of 0.21 (P <0.05) and udder circumference was 0.11 (P <0.05) and equation in Y = 2.423 - 0.398LA + 0.793TAB. However, there is no significant relationship between the height of the front udder and milk production.

The purpose of this study was to determine the effect of aflatoxin content of 9.58 ppb in feed on gastrointestinal biometrics and weight gain of laying hens in the early growth period. Thirty-six day old chicks (DOC) were used in this study and were divided into two groups P0 and P1. P0 (control group) was fed with 100% basal diet and P1 (treatment group) was fed a diet with a composition of 80% basal feed + 20% aflatoxin-containing feed. After the DOC was adapted, the first feeding containing aflatoxin was given from the 20th day to the 60th day. Data collection was carried out three times, namely the 20th, 40th, and 60th days. At the end of each period, the chickens would be euthanized to collect data on the weight and length of the digestive tract and body weight. Weight gain with time increased, but had no significant effect (p>0.05) between the control and treatment groups. Body weight continues to increase because the body's homeresis function is still running well. Observations on gastrointestinal biometrics showed significant differences (p<0.05) in oesophagus weight, proventriculus weight, ventriculus weight, jejunum weight, ileum weight and length, and cecum weight because aflatoxins have a direct effect on the digestive tract they pass. The conclusion of this study was that the provision of 20% aflatoxin-containing feed did not affect weight gain but had shown an effect on the biometrics of several gastrointestinal tracts.

Penelitian ini bertujuan untuk membuktikan pola pertumbuhan rahang bawah (mandibula) dombamerino jantan pada enam bulan pertama pascalahir tidak linier mengikuti pertambahan umur karenaaktivitas feeding dipengaruhi olehnya. Model pendugaan MARS (Multivariate Adaptive RegressionSplines) digunakan untuk pembuktian pola tersebut. Lima belas ekor anakan domba merino pascalahirdiukur panjang dan lebar rahang bawah setiap selang satu bulan selama enam bulan. Data totalpanjang dan lebar mandibula (cm) ditabulasi dan diolah dengan piranti MARS for Windows versi 2.0.Hasil analisis model MARS untuk hubungan umur terhadap panjang mandibula adalah Y = 13,022 +0,933 * BF2 {BF2 = max (0, umur – 4,000)}; {(BF =3, MI =1, M0 = 0, GCV = 3,148, R2 = 0,984)}, sedangkanuntuk lebarnya adalah Y = 4,940 + 0,382 * BF1 + 0,368 * BF2 {BF1= max (0, umur - 4,000) dan BF2 = max(0, 4,00 - umur)} ; {MI = 1, M0 = 0, GCV = 0,532 dan R2 = 0,984)}. Hasil ini menunjukkan pertambahanukuran panjang ataupun lebar rahang bawah berjalan linier dengan umur setelah anak domba merinomencapai umur empat bulan, sedangkan ini masih di bawah umur empat bulan, hubungan tersebuttidak linier, bahkan pada rentang umur satu menuju empat bulan lebar mandibula justru menampakkanpenyusutan. Pengamatan ini menyimpulkan bahwa, pola pertumbuhan bagian rahang bawah tidakberjalan linier dengan umur sebagai implikasi dari fungsi mandibula saat menyusu dan memamah-biakdi awal pertumbuhan anakan domba merino.

The technology of laserpuncture in livestock is an acupuncture technique using Laser (Light Amplification by Stimulated Emission of Radiation) that is fired at acupuncture points as biological receptors that are related to organs that can provide stimulatory effects. This research was conducted in the laboratory of Airlangga University for 30 days using a sample of 18 cambell ducks divided into 3 treatments and laser shot with 3 days interval. Treatment 0 as control, treatment 1 got laser treatment dose 0,2 joule and treatment 2 got laser treatment dose 0,5 joule. On the final result of the eggs that have been in the production of duck research for 29 days. P2 given laser shootings with a dose of 0.5 joule yielded more eggs with 158 grains compared to P1 given laser shootings with a dose of 0.2 joules yielding 126 grains and P0 with inactivated laser yielding a total of 86 grains. The conclusion of this study is the shooting of laserpuncture dose of 0.2-0.5 joule can increase egg productivity
