Abstract

ABSTRACKBangkalan Regency has a potensial local Dabung duck. A study was conducted on the duck eggs, including egg weight, egg index and hatching weight. This study aims to determine the relationship between egg weight and egg index with hatching weight. The research material was 150 eggs of Dabung duck. The origin of eggs was from the parent duck with the age  ±7-9 months and the age of  eggs was 1-5 days. Research methods the experiment with how to incubate Dabung duck eggs in a simple to use machine incubate. Dabung duck analysis result showed average egg weight 63,65g/egg, egg index 76,50% and hatching weight 43,03g/tail. Positive correlation relationship between egg weight with hatching weight and give a real influence (P<0.05), while the egg index with hatching weight shows a positive correlation relationship and shows real influence (P<0.05). The results of the regression analysis (A) shows Dabung duck egg weight with hatching weight Y=-1.809+0.704X. Results of a regression analysis (A) shows the egg index with hatching weights Y=10.619+0.424X. Regression coefficient of the egg weight and the egg index are positive. Results of the regression analysis (B) of egg weight and eggs index with hatching weight Y=-16.312+0.694X1+0.198X2. Regression coefficients are positive. Result showed that Dabung duck has average egg weight 63.65 g/egg, egg index 76.50% and hatching weight 43.03g/tail. Correlation between egg weight and egg index with hatching weight was significant (P<0,05). Regression (A) and (B) in Dabung duck indicate the of the relationship of egg weight and egg index to hatching weight is positive. Keywords :

Abstract

The aims of present study was to evaluate the qualitative and quantitative characteristics of imported sheep such as Texel crossed and Dorper sheep, compared with local sheep (Fat Tail Sheep/FTS) in almost the same region, namely Pujon and Karangkates. This research was a field research with case study methods and research materials as many as 39 for Texel crossed sheep, 19 for Dorper sheep and 37 for FTS. The age of the sheep ranges from 1.5 to 3 years (some have their first calf). Qualitative data were analyzed by Population Genetics Analysis and quantitative data were analyzed by One-Way Design Anova using Minitab software version 13. The results showed that: (1) Qualitative traits in Texel crossed , Dorper and FTS sheep showed that some traits underwent fixation where one of the traits was fixed. One allele in Texel crossed and Dorper sheep has disappeared and no longer exist in its origin place such as horned and hornless traits, white body color and black head, erect ears, while in FTS sheep it is still polymorphic, especially in the hornless and drooping ears in FTS. The white color on the FTS seems to have been fixed, because the dominant gene frequency/ p = 1 and the recessive gene frequency/ q = 0. (2) The quantitative traits such as body weight, in which the body weights of the Texel crossed , Dorper and FTS breed were different in the study, and the Dorper sheep the highest body weights, while the body weights of Texel crossed and FTS sheep were almost the same. Dorper sheep had the highest head index, and Texel crossed sheep and FTS sheep had the same head index. It was concluded that Texel crossed and Dorper sheep had many fixed qualitative characteristics such as horns, erect and drooping ears, white body color and black head in FTS sheep were quite polymorphic in horns and erect and drooping ears. The best growth of Dorper sheep because Dorper sheep was originated from a crossing between Dorset and Black Persian sheep.
