Western Visayas has largest population of native chickens in the Philippines; however, data on the phenotypic and genetic diversity is limited. Eight hundred and ten chickens from 270 different flocks, from six provinces within the region were chosen for characterization. Data collected includes farmer selection practices, means of identifying genetic groups and information on phenotypic traits of native chickens. This information was analysed using statistical tools suggested by FAO. Phenotypic diversity and equitability of distribution were analysed using Simpson's diversity index and equality of distribution. Results showed that native chicken genetic resources are comprised of two types, the Jolo and Bisaya; the latter was further divided into Bisaya–Cluster I and Bisaya–Cluster II. Jolo chickens were the heaviest (P < 0.01) but comparable with Bisaya–Cluster II in terms of egg weight, head shape and phenotypic distance. They all had higher diversity and equitability of distribution in their plumage colour and pattern, though the iris and shank colour had higher diversity but had limited distributions. Bisaya–Cluster II and Jolo chickens had higher diversity and above average distribution in liveweight. They were also homogenous in feather morphology and distribution; head and breast shape, and skeletal variants. Thus, the observed diversities and distributions can be used in identifying genetic materials for any breeding undertakings.

The Nilagiri sheep is a dual utility (fine wool and meat), native to the Nilagiri hills of Tamil Nadu. It is known for its adaptability to high altitude and low input system of rearing. At present, this breed is endangered with less than a thousand numbers existing, of which about 50 percent is maintained at Sheep Breeding Research Station, Sandynallah. Efforts are on to conserve the breed in-situ. Generation interval (GI), pedigree completeness level, inbreeding coefficient (F), average relatedness (AR), effective population size (Ne), and effective number of founders (fe) and ancestors (fa) were studied for the breed. Pedigree analysis was carried out using data available at the research station on 5 051 animals from 1965 onwards using ENDOG ver. 4.8. Higher values of pedigree completeness (more than 80 percent for 5th generation), balance in percent of ancestors between sire and dam pathways and higher equivalent complete generations (7.12) for the reference population were indicative of the depth in pedigree. The GI, F, and AR were 3.36 years, 2.17 and 3.45 percent, respectively. Ne based on maximum number of generations and individual increase in inbreeding was 298.83 and 97.25, respectively. fe and fa were 59 and 41, respectively, for the reference population. F was far from critical values of inbreeding and fe/fa ratio indicated absence of stringent bottlenecks. The effective population size was on the higher end of the range reported for endangered sheep breeds. The knowledge on genetic diversity and effective population size coefficients would support the cause of conservation.

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).

The phenotypic correlations between selected body conformation traits and milk off-take of three indigenous cattle breeds were evaluated against a backdrop of widespread traditional practice of identifying better milking cows and heifers using these traits. It was conducted in Fogera, Dembia and Wogera districts of northern-western Ethiopia. One-shot exploratory field visits were used to randomly identify sample cattle herds. Data were collected on eight quantitative and six qualitative body conformation traits as well as milk off-take from 126 sample cows. Pearson's correlation coefficients were determined between these traits and milk off-take for large, medium and small categories of navel flap-size categories. Results show that the average daily milk off-take varies significantly between categories of udder size, size of milk vein and neck length mainly not only in Fogera but also in Dembia and Wogera cows. Statistically significant phenotypic correlations exist between all the quantitative conformation traits and milk off-take in the three breeds but the type and strength of these associations are variable, indicating breed specificity of these associations. The significant correlations between width and length of navel flap with milk off-take are consistent with traditional knowledge of farmers of using navel flap size as an indicator of better milk production in these indigenous cows. The negative correlations of milk off-take with dewlap width in both Fogera and Wogera cattle, especially under the large navel flap category, are in agreement with the indigenous knowledge of these communities about these associations. It was therefore concluded that these traditional subjective practices can be improved by introducing convenient ways of objectively measuring these traits and using them in more conclusive and predictable ways.

The survey, which had for its main objective, the morphobiometrical characterization of the local chicken was carried out from December 2010 to March 2011 in 20 villages in Lobaye Division in the Central African Republic. It was carried out on 474 adult females and 183 adult males. The main results show that the morphological features are very heterogeneous. Indeed, five main types of feathering were observed: normal feathering (75.8%), crested type (10.4%), naked neck (7.0%), feathered tarsus (5.9%) and frizzle type (2.3%). The colouration of feathers is heterogeneous, with a predominance of the white (18.0%), wild (13.4%) and mahogany (11.1%) colours. The single comb is more frequent (95.8%), and is generally red (33.8%) or pink in colour (55.1%). Earlobes are red (24.7%), white (24.0%), white centred (18.1%), yellow (16.1%) or pink (14.6%). The wattles are mainly red (55.4%) or pink (35.2%). The tarsi are mainly yellow (40.6%) or white (37.9%). With regard to the biometric characteristics, the average weight of the local chicken of Lobaye is 1176 ± 206 g for females and 1514 ± 296 g for males. The live weight and most body measurements vary according to the sex and the feathering type. The live weight and the body measurements are significantly (P < 0.01) higher in the males. In the same way, the animals with feathered tarsi are heavier and bigger than the other phenotypes.

Characterization of indigenous animal genetic resources is a first step in providing much needed information for the conservation and utilization of useful genotypes for future needs. The study was undertaken to estimate heritability of traits of economic importance in local chicken populations from the forest and savannah zones of Ghana. A restricted maximum likelihood animal model was applied to growth data of local chickens from hatch to 40 weeks to estimate heritability, phenotypic and genotypic correlations of body weight and shank length. Heritability, phenotypic and genotypic correlations were also calculated for egg number and egg weight. High genetic and phenotypic correlations were obtained between body weight and shank length. Average heritability estimates were 0.54, 0.42, 0.30 and 0.47 for body weight, shank length, egg number and egg weight, respectively. These moderate-to-high heritability estimates indicate that these traits could be targeted in genetic improvement programmes for local chickens.

Animals should have the capacity to adapt to changing environmental pressures to ensure sustainable productivity. The easier an animal can adapt to disease burdens without extra cost to the farmer, the more profitable the enterprise becomes. Effective immune response protects organisms against disease insults and contributes to improved productivity. Primary immune response of Ghanaian local, Sasso T-44 and broiler chickens to sheep red blood cell (SRBC) antigens was measured 5 days post-inoculation. Antibody levels were determined by haemagglutination. Local ecotypes and Sasso T-44 chicken were superior to broilers in terms of their ability to respond to antigens. Female chickens produced more antibodies in response to increased concentration of SRBC antigens while the opposite was true in the male population. Further investigation of the genetic correlation between production performance and immune response of various chicken breeds will help establish the effect of, for example, high growth rate of broilers on their immunological status.

The Ardennaise breed is emblematic of the Belgian poultry diversity. We compared two varieties of the breed, the golden black and the silver black. The comparison encompassed: (i) the morphology of adult birds, (ii) the growth, carcass characteristics and meat quality of broilers 22 weeks old, (iii) the laying rate during 52 weeks and the egg quality. Significant differences were observed in the size of mature males and females: body weight, diameter and length of the tarsus, size of the comb and wattles. The two varieties did not differ concerning the carcass and meat quality traits. The golden black has a higher laying rate and a higher yolk / albumen ratio, but lays lighter eggs. It could be interesting to complete this study by molecular markers analysis to evaluate the degree of genetic diversity between the two varieties.

A household survey and measurements of different body traits from 120 households and from 1 009 goats were collected to characterize the production system and morphological features of Western lowland and Abergelle goat breeds of Ethiopia. Goats were kept for multifunctional roles in both areas, but mainly to generate cash. The average ± SD of flock sizes per household were 10.8 ± 7.25 and 48.56 ± 52.21 for Western lowland and Abergelle, respectively. Production characters such as body conformation, multiple births and milk yield were reported as major selection criteria of breeding goats. The majority of Abergelle goats have red brown (23.8 percent) and brown (19.7 percent) coat colours with short and smooth hair. All Abergelle goats have horns, 11.1 percent have wattles, 8.0 percent of males have ruff. White (20.4 percent) and a mixture of white with other colours were the predominant coat colours of Western lowland goats. A total of 42.3 percent males and 5.1 percent females of the Western lowland population have ruff. The least square means of body weight, chest girth, body length and height at withers of Western lowland female goats were 24.00 ± 0.19 kg, 65.27 ± 0.23 cm, 54.8 ± 0.21 cm and 62.60 ± 0.22 cm, respectively. The corresponding values for Abergelle female goats were 18.34 ± 0.22 kg, 61.03 ± 0.27 cm, 51.00 ± 0.24 cm and 58.99 ± 0.25 cm, respectively. Breed improvement programmes in these areas should take into account the multifunctional roles of goats, goat breeding practices and traits preference of the farmers.

The Global Plan of Action (GPA) for Animal Genetic Resources (AnGR) adopted by FAO recognizes the role of AnGR for food security through improved productivity while maintaining genetic diversity. A critical issue for conservation and genetic improvement programmes is the availability of supportive infrastructure. The objective of the present study was to assess existing and needed infrastructure for sustainable use of AnGR in a sample of countries in Southern and Eastern Africa. Information was primarily obtained from semi-structured interviews with key personnel in animal breeding during country visits. Countries studied are at different stages of development. No complete breeding programmes are in place but some conservation programmes exist in most countries. Except for a few cases, livestock recording as basis for R&D and breeding practice is lacking. The institutional setup to support animal breeding programmes is fragmented and needs to be better integrated. Shortage of skilled personnel is noted as the most serious constraint for development. Countries with least university training in animal breeding have least developed AnGR activities. However, since the GPA was agreed upon, many countries have re-casted their policies and make efforts to develop breeding policies. A change in mindsets aiming at closer collaboration among institutions, farmer involvement and capacity development and strengthening at all levels is suggested.

This paper analyzes the articles published in this special issue and also some material presented at the Session “Strategies to add value to local breeds” of the 61st Annual Meeting of the European Federation of Animal Science (EAAP) (August, 2010, Crete, Greece)1 or at other workshops dealing with the issue of adding value to local breeds. The analysis refers to the challenges facing local breeds and the different strategies that can be used to increase their value and thereby enhance their sustainability. These strategies can be categorized, inter alia, according to the species, the specific characteristics of the targeted breeds or production systems, the existence or absence of markets and the characteristics and dynamics of the breeders and other stakeholders. The paper is structured as follows: presentation of an overview of the challenges involved; this is followed by a discussion of strategies for adding value to breeds, which is illustrated with examples; an analysis of the key factors affecting such strategies and ends with some conclusions. Questions remain regarding the society's responsibility for providing support to farmers that keep local breeds that are at risk of extinction and regarding what actions are appropriate when such a breed that was once at risk becomes self-sustainable or, in contrast, when a breed ceases to be self-sustained.
