“…This was expected, as most animals in the Federal District were imported from Sergipe due to a lack of Federal sanitary barrier between these States and the action of a strong association of breeders. The type of animal found in both regions is morphologically similar and different from animals found in other places in the Northeast region, as recently reported with morphometric markers (Carneiro et al, 2010). These cited authors noted that the pattern is consistent with the hypothesis for the existence of an "Old Santa Inês" breed versus the "New Santa Inês".…”

ABSTRACT. Santa Inês is the most common hair sheep breed in Brazil and probably has the highest genetic diversity among sheep breeds in this country. Successful breeding programs for Brazilian sheep breeds are not common for various reasons, including a lack of control of parentage in the flocks. We developed an allele frequency database for 23 STR loci for the Santa Inês breed based on 285 animals sampled from five populations distributed across the central-western and north-eastern regions of Brazil.

“…The discriminant analysis based on significant F-values indicated body weight, body length, height at withered, chest width, ramp length, pelvic width, horn length and ear length as the linear measures permitting discrimination between the Woyto-Guji and Central Highland goats. Some of these discriminating variables are similar to those reported by other researchers in sheep (Carneiro et al, 2010;Yakubu and Ibrahim, 2011) and goats . The higher the overall percent classification rate (hit rate) is also an indication of the fact that, the two breeds belong to different breeds.…”

The study was conducted to differentiate the Woyto-Guji and Central Highland goat breeds of Ethiopia and derive the most accurate linear regression equation for live body weight prediction. Morphological measurements were taken on randomly selected 531 adult female goats (263 from Woyto-Guji and 268 from Central Highland). Positive and highly significant (P<0.001) correlations were observed between body weight and most independent body measurement variables in both breeds. The highest relationship between chest girth and body weight were illustrated in both breeds (r=0.85 for Woyto-Guji and r=0.82 for Central Highland). The multiple regressions found five parameters to be significant (P<0.05) for Woyto-Guji (chest girth, body length, pelvic width, chest width and ramp length) and Central Highland (chest girth, body length, ramp length, horn and ear length) with R 2 values of 84% and 79%, respectively. Body weight, body length, height at wither, chest width, ramp length, pelvic width, horn length and ear length had a significant (P<0.15) discriminating power on the breeds. Nearest neighbor discriminating function analysis shows that 93.23% of Woyto-Guji and 92.96% of Central Highland breeds were classified into their source population. The morphological variations obtained in this study should be consolidated with more evidence drawn from genetic analysis.

“…Based on height at wither and body weight, indigenous goat in Ethiopia are classified in to three classes (large, >65 cm and weighing 37-50 kg; small, 51-65 cm and weighing 26-36 kg; dwarf, <50 cm and weighing 18-25 kg) (Kassahun and Solomon, 2008). The improvement on local goat depends on the phenotypic information for mass selection, whereby individuals with better trait values is chosen to be parents of the next generation (Carneiro et al, 2010). Maefur goats population is one of the potential indigenous goat breeds found in the regional government of Tigray but not yet well described with limited attempts to characterization for sustainable utilization and designing management intervention under smallholder farmer.…”

The study was conducted in Erob district eastern Tigray, Ethiopia to phenotypic characterize Maefur goat based on physical body feature and linear body measurements. Six hundred (297 male and 303 female) goats were randomly selected and grouped into four age groups of 0, 1, 2 and ≥3 PPI. General Linear Model (GLM) procedure of SPSS version 16.0 and descriptive statistical analysis were were used to summarize the collected data. Short ear size (12.3 cm for male and 11.8 cm for female), long and thick horn, medium body size (42.8 kg for male and 32.7 kg for female), and large heart girth (82.1 cm for male and 73.4 cm for female) are the major body characteristics of Maefur goat breed. There was a significant (P< 0.05) effect of sex and age on live body weight and linear measurements. Mean± SE of live body weight, heart girth, body length and height at wither in male were 34.7±0.57 kg, 75.3±0.53 cm, 64.3±0.61 cm and 64.7±0.46 cm, respectively while in female 28.9±0.35 kg, 70.0±0.33 cm, 60.0±0.40 cm, and 59.3±0.31 cm, respectively. For heart girth in these age groups were 61.1±0.53, 69.4±0.33, 70.6±0.4 and 77.7±0.39 cm, respectively while body length were 50.3±0.43, 56.8±0.42, 59.3±0.58 and 68.2±0.42 cm, respectively. For height at wither in these age groups were 54.0±0.45, 59.1±0.35, 58.4±0.32 and 66.5±0.40 cm, respectively. Heart girth and height at wither were significantly (P<0.05) different among the age groups except between 13-18 and 19-24 months. The study revealed that large heart girth is a unique characteristic of the Maefur indigenous goat. The study concluded that Maefur goat breed is identified as one of the potential goat breed in Tigray, Ethiopia.
