“…Negative correlation coefficients were also recorded for stockiness, long-leggedness and body weight (r= -0.24 and -0.22; p<0.01 respectively). High positive relationships among YAKUBU traits suggest that they are under the same gene action and can also be predicted from one another singly or in combinations (Ngapongora et al, 2004;Ogah et al, 2009). The varying phenotypic correlation coefficients in the two sexes suggest sexual differences in the genetic architecture of the birds.…”

SUMMARYSexual dimorphism was examined in 221 randomly selected adult African Muscovy ducks extensively reared in north central Nigeria using univariate and multivariate measures of body size and skeletal proportions. The body parameters investigated included body weight, 8 primary linear body measurements [breast circumference (BTC), thigh circumference (THC), body length (BDL), bill length (BLL), neck length (NKL),foot length (FTL), total leg length (TLL) and wing length (WNL)] and 4 morphological indices (massiveness, stockiness, long-leggedness and condition index). The univariate analysis showed male dominance (p<0.05) in all the morphometric measurements, with the exception of stockiness and longleggedness where significantly higher mean values were recorded for females. Low, moderate and high positive and negative correlations among the body size and shape characters of the ducks were recorded. The canonical discriminant analysis on body weight and primary linear body measurements revealed that wing length was the most discriminating variable between the sexes, followed by body weight, neck circumference, total leg length, body length and foot length respectively. Three other variables not qualified to enter the model were expunged. The single discriminant function obtained (D= -3.116 + 0.280WNL+ 0.921BWT + 0.191NKL -0.196TLL -0.063BDL -0.283FTL) correctly classified 91.4% of individuals of known-sex ducks. This might aid in ecological studies, conservation and improvement of the indigenous ducks. RESUMENSe estudió el dimorfismo sexual en 221 patos, Muscovy Africanos, adultos, seleccionados al azar, explotados extensivamente en la región norte centro de Nigeria, empleando para ello medidas uni y multivariadas del tamaño corporal y proporciones del esqueleto. Los parámetros corporales investigados incluyeron: peso corporal, ocho medidas lineales corporales (circunferencia de la pechuga, BTC; circunferencia del muslo, THC; longitud del cuerpo, BDL; longitud del pico, BLL; longitud del cuello, NKL; longitud del pie, FTL; longitud total de la pata, TLL y longitud del ala, WNL) y cuatro índices morfológicos (masividad, solidez, largura de la pata e índice de condición). El análisis univariado mostró la dominancia del macho (p<0,05) en todas las medidas morfométricas, salvo para solidez y largura de la pata en los que se registraron valores medios significativamente más altos para las hembras. Correlaciones positivas y negativas, bajas, moderadas o altas, fueron encontradas entre tamaño corporal y caracteres morfológicos de los patos. El análisis discriminante canónico para el peso corporal y medidas lineales primarias del cuerpo, reveló que la longitud del ala fue la variable más discriminante entre sexos, seguida del peso corporal, circunferencia del cuello, longitud total de la pata, longitud del cuerpo y longitud del pie respectivamente. Otras tres variables no cualificadas para entrar en el modelo fueron eliminadas. La función discriminante simple obtenida (D= -3,116 + 0,280WNL+ 0,921BWT + 0,191NKL -0,196TL...

“…As a food source of meat it is better to use a male Muscovy ducks in accordance with Yakubu (2011), in which the male Muscovy ducks are sold to generate income and the female Muscovy ducks are for breeding. The percentage of carcass weight, breast weights and thigh weight were higher in male Muscovy duck than that in the females because male had body weight, body length, body height greater than female (Ogah, 2009).…”

Abstract. Fat, cholesterol and fatty acid profile of breast and thigh meat of 12 Muscovy ducks (6 drakes) aged 8 weeks from the local farm in Bogor, West Java were analyzed in thus study. In general, Muscovy ducks were fed with rice bran twice a day and free-ranged in the backyard. The nutrition of rice bran is varied in crude protein, crude fiber, fat, and ash content. Muscovy ducks were slaughtered and the percentage of carcass weight, fat, cholesterol and fatty acid profile of the breast and thigh meat were measured and analyzed. The result showed that the breast meat had higher (P<0.05) ω3 total fatty acid EPA (C20:5ω3) but DHA (C22:6ω3) and linolenic acid (C18:3ω3) were not significant compared to that of thigh meat. Concentration of linolenic acid in breast meat ranged from 0.26 to 0.51% of fat and 0.35 to 0.39% of fat in thigh meat. Linoleic acid (C18:2ω6) in breast and thigh meat was 7.64 -10.73% and 5.17 -13.93 % fat, respectively. DHA concentration ranged from 0.13-1.31% fat in breast meat and EPA in thigh meat was approximately 0.08-0.32 % fat. EPA was significantly higher (P<0.05) in breast meat (0.03-0.28 %) than thigh meat (0.05-0.08 %) The study produced ω 6:3 ratio ranged 6.50-24.14 and 8.94-31.64 in breast and thigh meat, respectively. Key words: Muscovy duck, fatty acid, fat, cholesterol.Abstrak. Penelitian ini bertujuan untuk mendapatkan informasi tentang kandungan leamk,cholesterol dan profil asam lemak dari daging dada dan daging paha entok (Muscovy duck) yang dipelihara secara tradisional oleh masyarakat. Entok diberi pakan dedak padi yang mempunyai kualitas rendah dan beragam dari 6 peternak yang ada di kota Bogor, Jawa Barat, Indonesia. Dedak padi diberikan dua kali sehari yaitu pagi dan siang kemudian entok di lepas disekitar halaman rumah. Penelitian ini menggunakan 12 sampel entok berumur 8 minggu kemudian dipotong dan diukur karkas, persentase daging dada dan paha dan kandungan lemak,cholesterol dan asam lemak. Hasil penelitian diperoleh daging dada lebih tinggi kandungan total asam lemak ω 3 (P<0.05), EPA (C20:5ω3) (P<0.05) daripada daging paha tetapi DHA (C22:6ω 3) tidak berbeda nyata. Kadar asam linolenat (C18: 3ω3) pada daging dada berkisar dari 0,26 to 0,51% total lemak dan 0,35 to 0,39 % total lemak di daging paha. Asam linoleat (C18:2 ω 6) berkisar 7,64 -10,73% total lemak di daging dada dan 5,17 -13,93 % total lemak di daging paha. Kadar DHA (C22:6ω 3) berkisar 0,13-1,31% total lemak di daging dada dan EPA berkisar 0,08-0,32 % total lemak di daging paha. Kadar EPA lebih tinggi (P<0,05) di daging dada dibandingkan daging paha berkisar 0,03-0,28 % total lemak (daging dada) sampai 0,05-0,08 % total lemak (daging paha). Penelitian ini menghasilkan rasio ω 6/ ω 3 berkisar 6,50-24,14 di daging dada dan 8,94-31,64 di daging paha.

ABSTRAKPenelitian ini dilakukan untuk mengidentifikasi ukuran-ukuran tubuh entok di Kabupaten (Magelang, Demak dan Pekalongan), Provinsi Jawa Tengah. Materi yang digunakan yaitu 210 ekorentok yang telah dewasa tubuh dengan rerata umur 7 bulan (70 ekor/kabupaten, 35 ekor jantan dan 35 ekor betina) pada masing-masing kabupaten. Variabel ukuran tubuh yang diamati meliputi bobot badan, panjang paruh, lebar paruh,panjang kepala, lingkar kepala, tinggi kepala, panjang leher, lingkar leher, panjang sayap, panjang badan, lingkar badan, tinggi badan, panjang dada, panjang femur, panjang tibia, lingkar tibia, panjang maxilla, dan panjang jari kaki ketiga. Data yang diperoleh dianalisis univariate dan multivariate dengan bantuan software SAS. Jarak Mahalanobis dianalisis menggunakan MEGA 5 (UPGMA) untuk membentuk pohon filogeni. Hasil penelitian menunjukkan bahwa entok jantan dan betina pada masing-masing kabupaten menunjukkan perbedaan (P<0,05) pada semua variabel yang diamati. Ukuran panjang sayap dan lingkar badan menjadi variabel pembeda pada entok antar kabupaten. Berdasarkan matrik jarak genetik, entok Magelang memiliki kedekatan dengan entok Pekalongan, tetapi berjauhan dengan entok Demak. Kata kunci: karakteristik fenotipik, ukuran tubuh, entok Body Measurement of Muscovy Duckin Three Regency of Central Java ABSTRACTThe study was conducted to identify the body measurements of Muscovy duck among three regency (Pekalongan, Magelang dan Demak)
