A study on morphological body conformation of Alabio, Bali, Khaki Campbell, Mojosari and Pegagan ducks was carried out to determine the genetic distance and discriminant variables. This research was held in Research Institute for Animal Production, Ciawi, Bogor using 65 Alabio ducks, 40 Bali ducks, 36 Khaki Campbell ducks, 60 Mojosari ducks and 30 Pegagan ducks. Seven different body parts were measured, they were the length of femur, tibia, tarsometatarsus, the circumference of tarsometatarsus, the length of third digits, wing and maxilla. General Linear Models and simple discriminant analysis were used in this observation (SAS package program). Male and female Pegagan ducks had morphological size bigger than Alabio, Bali, Khaki Campbell and Mojosari ducks. Khaki Campbell ducks were mixed with Bali ducks (47.22%) and Pegagan ducks from isolated location in South Sumatera were lightly mixed with Alabio and Bali. Mahalanobis genetic distance showed that Bali and Khaki Campbell ducks, also, Alabio and Mojosari ducks had similarity, with genetic distance of 1.420 and 1.548, respectively. Results from canonical analysis showed that the most discriminant variables were obtained from the length of femur, tibia and third digits. Â Key words: Duck, genetic distance, morphological

The observation on morphological body conformation of English Spot (ES), Flemish Giant (FG), New Zealand White (NZWm), and Rex (Rexm) from Magelang, Central Java, and New Zealand White (NZWb), Rex (Rexb), Satin (Satin) and RS (RS) from Balitnak-Ciawi, were carried out to determine estimation of Mahalanobis genetic distance.Â This research was held in Magelang (Central Java) and Balitnak-Ciawi (West Java), 237 heads of Rabbits were used. Eleven different body parts were measured, those were head (length and width), ear (length and width), chest (girth, depth, and width), humerus length, radius-ulna length, tibia length and body length. General Linear Models were used in this observation (SAS package program). Simple discriminant analyses as further analyses were done for head (length and width), chest (girth, depth, and width), humerus length, radius-ulna length, tibia length and body length. ES, FG and NZWm rabbits had morphological size bigger than others. Mahalanobis genetic distance showed that NZWm and NZWb, Rexm and Rexb were had differences with genetic distances of 5.89139 and 6.75571 respectively. Rabbits from Magelang and from Balitnak were different on morphometric with mahalanobis distance of that region ranges were 4.89426 to 6.96749. Results from canonical analysis showed that the most discriminant variables were obtained by chest girth, chest width and humerus length on first canonical and head length on second cannonical.

A study on morphological body conformation of Cihateup, Cirebon and Mojosari ducks was carried out to determine the genetic distance and discriminant variables. The research was done at PT Dwi Mitra Daq, Gunung Sindur, Bogor, using 30 Cihateup, 30 Cirebon and 30 Mojosari ducks, from September to November 2004. Length of neck, wing, circumference of chest, deep chest, body weight, circumference of tarsometatarsus, length of chest, third digit, tarsometatarsus, tibia, femur and maxilla were measured to observe their body sizes to determine the genetic distance and discriminant variables. Data obtained were analyzed by using GLM (General Linear Model) and simple discriminant analysis with SAS package program version 6.12 and program MEGA2 to make the construction of tree fenograms. Cihateup ducks had larger body size (i.e. length of neck, wing, circumference of chest, deep chest, length of third digit and femur) than Cirebon and Mojosari ducks, but were smaller on length of tarsometatarsus than Mojosari ducks. Results from canonical analysis showed that the most discriminant variables were obtained from the length of third digit tarsometatarsus, tibia and femur. Cihateup ducks were mixed with Cirebon ducks (36,67%), Cirebon ducks were mixed with Cihateup ducks (43,33%) and Mojosari ducks (3,33%), Mojosari ducks were mixed with Cihateup ducks (3,33%) and Cirebon ducks (13,33%). Mahalanobis genetic distance showed that Cihateup and Cirebon ducks had a genetic distance of 0,880, Cihateup and Mojosari, and, Cirebon and Mojosari had 1,786.

Identification of genes in rabbits correlated to economic traits were intended to improve and develop their genetic quality. The objective of this research was to analyze the variability of growth hormone gene (GH) in three rabbit breeds, i.e. Rex, Satin, and Reza (Rex and Satin crosses) then was associated with ultrasound imaging of Longissimus dorsi muscle and perirenal fat thickness. Identification of the variability of growth hormone gene was analyzed using PCR RFLP technique from blood samples of 33 mature male rabbits in Indonesian Research Institute for Animal Production (IRIAP). Thickness of Longissimus dorsi muscle and perirenal fat were imaged and measured by using ultrasound unit at 2nd to 3rd lumbar vertebrae in the left body side. PCR product of GH gene fragment (231 base pair /bp) was digested with restriction enzyme Bsh1236I. PCR-RFLP patterns were allele T resulted in an undigested fragment of 231 bp; allele C resulted in fragment of 169 bp and 62 bp. The result showed that Bsh1236I GH gene had three genotypes, i.e. CC, TT, and CT. There were signifficant association of Longissimus dorsi muscle thickness between rabbit breed (P<0.05). There was no significant association between GH Bsh1236I gene polymorphism and imaging ultrasound of Longissimus dorsi muscle and perirenal fat thickness. The association of characteristic genotype of GH|Bsh1236Igene with measurement phenotype was not significant, however it had potency as marker assisted selection (MAS). Key words: growth hormone gene, Longissimus dorsi, perirenal fat, rabbit, ultrasound
