An exploratory field survey was conducted in Horro Guduru Wollega Zone, Ethiopia, to phenotypically characterize indigenous goats. Eight qualitative and fifteen quantitative traits from 612 goats were considered. All data were analysed using SAS 9.2, version 2008. The dominant coat colour types in Guduru district were black (35.29 percent), whereas in Amuru district, the dominant coat colour types were white and brown with brown dominant (18.63 percent) and brown (17.65 percent). In Horro district, the dominant coat colour types were grey (21.57 percent) and black and white with black dominant (15.69 percent). Morphometric measurements (body weight (BW), heart girth and body length) indicated that the Amuru and Horro goats were significantly (P < 0.05) higher than the Guduru goats. Male goats were consistently higher than female goats in all variables except pelvic width (PW). BW could be predicted from the regression equation y = −45.22 + 1.04x for does and y = −59.71 + 1.25x for bucks, where y and x are the BW and the heart girth, respectively. This phenotypic information serves as a basis for designing appropriate conservation and breeding strategies for goats in the study area. However, it should be substantiated with genetic characterization to guide the overall goat breeding and conservation programmes.

This study was conducted in three villages of the Trarza region of Mauritania. The purpose of this study was to describe the management of and to characterize the local chicken. In the three surveyed villages, all the breeders were interviewed according to a questionnaire drafted in French and translated orally into hassanya or poular (national languages) as necessary. 56 poultry breeders were surveyed. Measurements were carried out on 260 adult chickens with 191 females and 69 males. The results showed that family poultry rearing is an activity managed by women. In spite of its socioeconomic importance, it is not considered as a main activity among the farmers responding to the survey. Feed resources deficiencies, animal health and the low productivity of the chickens were declared as the main concerns of the breeders. The average age of females when they start to reproduce is 6 months. The average weight of males was 1324 ± 249 g. That of females was 1028 ± 229 g. The average weight for both sexes together was 1107 ± 268 g. The average weight of the egg was 31 ± 4.81 g. The average weight of a chick on any given day was 26 ± 6.03 g. All the considered physical measurements were significantly higher (p < 0.05) in males. The variability of characters observed offers possibilities for genetic improvement (selection or crossbreeding). In the local chicken, the plumage was highly varied and presented several tints.

Characterization and genetic diversities among members of a species are fundamental to their improvement and conservation. This study was conducted to characterize and estimate genetic diversity in the ecotypes of the locally adapted Muscovy duck in Nigeria using blood proteins (haemoglobin, transferrin and albumin) and enzyme (carbonic anhydrase) markers. Blood samples collected from 20, 40 and 20 adult Muscovy ducks sampled randomly from the Rain Forest, Derived Savanna and Guinea Savanna ecotypes, respectively, were typed for blood proteins and enzyme polymorphism with cellulose acetate paper. Genetic variability in the studied population was accessed using heterozygosity (H), effective number of allele (ne) and polymorphism (percent P). All the 13 allelic variants expressed at the four loci were expressed in the Derived Savanna ecotype but 12 each in the Rain Forest and Guinea Savanna ecotypes. Results showed that all the four loci were polymorphic (100 percent) and the estimated heterozygosity among them was similar (0.424–0.481). Similarity in the estimated genetic variability parameters among ecotypes indicate that the sub-populations understudy was under similar evolutionary forces and there were no appreciable differences among them.

The study was conducted on Boran bulls from three age groups (2, 3 and 4 years) reared at two different locations in Southern Ethiopia. The study was conducted to assess the different morphometrical measurements in Boran bulls, to estimate live weight of the bulls using step-down regression equations and also to calculate structural indices for assessment of type for which the breed was developed and thus assist in the selection of the bulls. The feedlots were situated in Meki district and varied both in location and the type of management, with the second feedlot being better managed than the first. The morphometric traits included in the study were height at withers (HW), height at rump (RH), body length (BL), heart girth (HG), head width (WFH), neck circumference (NC), neck length (NL), chest width (CW), rump length (RL), hip width (WH) and flank width (FW) and the body weight (BW). The results indicated that while the skeletal measurements HW, RH and BL did not vary (P < 0.05) between bulls of a particular age across the two feedlots, the other parameters were higher among the bulls reared in the feed lot with wind breaks and situated away from lake Ziway. The results of the step-down regression equations indicated that BW could be assessed using various morphometrical measurements viz. NL, NC, RL, WH and HG. The parameters included varied both across the age groups and locations. The results related to the structural indices indicated that the Boran bulls had posterior alignment and had higher CW than HW.

The aim of the study was to identify and characterize the phenotype of goat genetic resources in the Bench Maji zone, south western Ethiopia. Focus group discussions, observation of physical attributes and morphology, and morphometrical measurements were employed for data collection. Descriptive statistics, chi-square tests, general linear model (GLM) and two-step cluster analysis were employed to analyse the data. The results of the analyses revealed that 90.7 percent of the female and 88.4 percent of the male goats have straight facial profile. Horns in the majority of females (85.7 percent) and males (73.4 percent) are straight with backward direction in 72.6 percent of females and 84.2 percent of males. In most cases the female goats lack ruffs (88.2 percent), wattles (73.8 percent) and beards (68.3 percent). Averaged quantitative traits of the female population were 56.97 ± 0.21 cm; 70.15 ± 0.27 cm, 60.08 ± 0.17 cm and 26.36 ± 0.21 kg for body length, chest girth, height at withers and body weight, respectively. The corresponding values of the male population were 60.81 ± 0.35 cm, 75.04 ± 0.50 cm, 64.47 ± 0.32 cm and 31.02 ± 0.50 kg, respectively. Goats from the different districts have shown significant (P < 0.01) differences in body length, height at withers and body weight of female and chest girth and body weight of males. 48 and 52 percent of the goat populations were distributed under two clusters indicating that the goat populations can be classified into two ecotypes (Meanit and Sheko).

A total of 700 adult female goats from Sétif area (Algeria), were investigated for eight qualitative morphological traits and 17 body measurements. Sampling included three environmental areas: Northern, Central and Southern area. Coefficients of variation ranged from 10.9 percent to 34.7 percent, showing high heterogeneity. Canonical analyses showed that differences in body measurements between the three area-populations were large and significant in all traits (P < 0.001). The shortest Mahalanobis distance was found between North-Center populations (2.8), while that between Center (4.0) and (8.6) between North-South populations were the largest. Discriminant analysis showed that most goat-populations were classified into their environmental-area, North (73.0 percent), Center (66.8 percent) and South (79.3 percent) with a few misclassified individuals. Correspondence analysis indicated no large differences between the goat populations; they were more homogeneous for qualitative traits. This information will constitute the basis for further characterization and develop conservation strategies for Algerian goat populations

This study aims to provide data on the physical profiles of the red goat of Maradi. It was conducted in the centre of the goat's main territory, and further comprised 4 departments of the Maradi area (Tessaoua in the east, Dakoro in the north, Madarounfa in the south and Guidan Roumdji in the west). This work was performed on 339 animals including 77 in the centre, 88 in the east, 69 in the north, 50 in the south and 55 in the west. It focused on the following measurements: height at withers, scapulo-ischial length, chest size, back length, length of the horns, ears and head, the presence of “pendeloques” and goatees, the coat color and structure of the hair. The results have shown differences between body variable measurements related to geographical position. In fact, the geographical position has significantly influenced body profiles, IGS and IAT indices (P < 0.0001). The dominant trend of the red color is probably an adaptation character of Maradi goats. Our contribution to define the standard of this breed of red goats should be summary as a population with medium size, short and erect ears, two horns (most developed in males) tilting back, short hair and the presence of a beard (beard developed in males) in both sexes. We also note the presence of “pendeloques” in some animals in the East of Maradi.

Serrana de Teruel is an endangered cattle breed raised traditionally in the mountainous areas of Southern Aragon (Spain). With the aim of recovering the breed, a characterization was carried out to determine the morphology, husbandry and genetic values of the Serrana de Teruel breed. Individuals showed a medium to high degree of homogeneity and harmony, most of the animals being of straight profile, and eumetrical and sublongilineal individuals, although smaller in size than other phylogenetically proximate breeds. Biodiversity studies showed good diversity values despite the breed's low effective population size (240 individuals in 2010). These studies provided the basis for a sustainable programme of genetic conservation. In order to guarantee long-term maintenance, germplasm banks contain 6400 doses of semen and 74 embryos. Concurrently, the commercial viability of the breed was studied by means of an analysis of carcass and meat quality from three commercial categories – yearling, bull and steer (castrated at 9 months old) – with ages at slaughter of 12, 22 and 22 months and live weights of 470, 720 and 660 kg,, respectively. Good performances and high-quality products with no commercial constraints in the beef market were obtained. Finally, a prospective study for a new beef quality product labelled ‘Serrana de Teruel’ was performed, according to the opinions of experts. These studies provide the standard requirements for the alternative production of a labelled beef product that might create an incentive for the production of the Serrana de Teruel breed among other breeds, and thus favour the conservation of the breed in the medium term.

Assessment of diversity is a prerequisite for the management and conservation of farm animal genetic resources. To study the morphological features of Fipa cattle in Southwestern Tanzania, 108 herds were studied. Fourteen body measurements (body weight, body length, height at withers, heart girth, ear length, ear width, horn length, horn-base thickness, horn-base spacing, horn-tip spacing, rump width, rump length, tail length and tail-base thickness) and qualitative traits were recorded from 307 animals. Measurements were classified according to location and animal sex. Both location and sex significantly (P < 0.05) influenced all the measurements, with castrates and bulls superseding cows. Most measurements were positively and highly significantly (P < 0.001) correlated with the body weight predicted accurately from heart girth. The animals had variable colour patterns, but being predominantly red (20.9 percent), pied black and white (18.6 percent), black (17.9 percent) and pied red and white (14.7 percent). All animals had sloping rumps and most (81.8 percent) had small-sized humps. Most (94.8 percent) animals had pyramid-shaped humps located in the cervico-thoracic position. Most (91.5 percent) animals had upward–forward oriented and lyre-shaped horns. All the animals had flat faces and backs, and laterally oriented ears. Most (97.1 percent) animals had medium-sized dewlaps, medium-sized teats (93.6 percent) and medium-sized quarters (87.2 percent). The navel flap was absent in most (87.6 percent) animals. Thus, the Fipa cattle can be classified as a medium-sized strain with considerable variation in body size and morphological features within and between districts.

Phenotypic characterization is critical in breed improvement and conservation. To determine the performance and morphological features of Ankole cattle in three livestock production systems (LPS) of Uganda, 248 farms were studied. Height at withers (HW), heart girth (HG), body length (BL), ear length, horn length (HL), distance between horn tips (HS) and body weight (BW) were then measured on 120 bulls and 180 cows. Data were analysed using LPS (crop livestock, agropastoral, pastoral), county (Gomba, Kazo, Kiboga, Mawoggola, Nyabushozi) and sex (females, males) as main factors. In the results, age at sexual maturity was 23.6 ± 0.5 months for bulls and 22.7 ± 0.5 months for cows. Age at first calving was 33.2 ± 0.5 months, whereas calving interval was 12.9 ± 0.8 months. Lactation length differed between LPS (5.5 ± 0.4, 6.3 ± 0.3 and 7.4 ± 0.2 months in agropastoral, crop livestock and pastoral, respectively). Mean daily milk off take was 2.2 ± 0.1 kg/cow whereas preweaning calf survivability was 90.0 ± 6.5%. Sex and LPS significantly influenced HW, HL and HS. Positive correlations were observed between BW and HG, BL and HL. Correlation coefficients were much lower in females than in males, except for BW vs HG and BW vs HW. Results show wide variations both in performance and morphology suggesting that within breed selection scheme and/or management improvement may lead to productivity improvements.
