The selection index will include traits measured during performance recording. These traits can be the same as in the objective or correlated to them. They will be adapted from the French sheep performance recording. Pre-weaning growth and reproduction parameters such as fertility and litter size will be recorded. In addition to these traits, post-weaning growth and faecal egg count (FEC) will also be recorded. FEC gives an indication of the level of parasitism of the animals. Genetic parameter estimationThe genetic parameters were estimated to calculate the weighting of the traits in the index (Gunia et al., 2010b). The experimental Creole goat flock at INRA Gardel provided enough data for the calculation of the genetic parameters. More than 20 years of data about growth and reproduction traits were available. Organisation of the breeding programmeThe mating scheme will be designed. A sample of interested farmers (owning 300 does in total) will select the Creole goat. They will sell improved reproducers to a ''user'' group of farmers. These users will rear Creole goats and sell them for meat purpose, either in totally pure breed systems, or by using Creole does as a maternal line for crossbreeding. The different organisations of the programme will be studied with extension services to choose the most adapted solution. ConclusionAs it happened for other indigenous breeds, the value of the Creole goat was long underestimated (Gauly et al., 2010). Technical, economical, and genetic factors were taken into account in this programme to allow a more efficient selection of the Creole goat. The disease resistance characteristic of Creole goat was emphasised along with growth and reproduction traits. All participants (farmers, research, extension services) were integrated in this project.

“…Genetic and phenotypic parameters estimation of growth traits of different goat breeds have been reported by several studies (Shrestha & Fahmy, 2007;Boujenane & El-Hazzab, 2008;Zhang et al, 2009;Al-Saef, 2013). Al Saef (2013) reported heritability of birth and weaning weight in Syrian Damascus and Boer goat were 0.41 and 0.21, respectively.…”

The aim of this study was to estimate genetic and phenotypic parameters of growth traits consisting of birth weight (BW), weaning weight (WW), 6 mo body weight (6WM), 12 mo body weight (12WM), and 18 mo body weight (18WM) of Ettawa Grade goats. The number of goat used to determine growth traits of BW, WW, 6WM, 12WM, and 18WM were 316; 316; 259; 259 and 165 heads, respectively. Data were analyzed using General Linear Model (GLM) to identify non-genetic effect. Estimation of genetic and phenotypic parameters including heritability, repeatability, genetic and phenotypic correlation were calculated using Restricted Maximum Likelihood and GLM. Genetic trends were calculated using the regression of mean breeding values on birth year. The results showed that parity and type of birth had significant (P<0.05) influence on all growth traits. Estimated heritability of birth,

“…Various studies have shown that improved management strategies are the key entry point for improving smallholder goat and sheep production, but also that there is potential for genetic improvement through selection (Bosso et al 2007; Kosgey and Okeyo 2007; Shrestha and Jahmy 2007). Yet, an explicit understanding of the varying nonfood functions of sheep and of goats as well as a comprehensive quantification of their keepers’ preferences for traits and breeding practices including applied selection criteria within and across urban settings is therefore indispensable for making locally and regionally valid recommendations and for establishing appropriate improvement initiatives.…”

Production objectives and breeding practices of urban goat and sheep keepers in West Africa: regional analysis and implications for the development of supportive breeding programs

To better understand the relative importance of the multi-purpose functions of small ruminants for their urban owners and related breeding practices including selection criteria, we undertook a comparative analysis across the West African cities of Kano (Nigeria), Bobo Dioulasso (Burkina Faso) and Sikasso (Mali). Semi-structured questionnaires were used to collect the required information from 301 sheep farmers (100, 102 and 99 in Kano, Bobo Dioulasso and Sikasso) and 306 goat farmers (100, 99 and 107 in Kano, Bobo Dioulasso and Sikasso). Sheep and goats were kept for a variety of reasons including income generation, insurance (sale for cash to meet unexpected expenditures) and economic security (sale for cash to support foreseeable expenses), social/religious functions and prestige in ownership. The relative importance given by respondents to the different functions varied significantly (p < 0.001) across cities and between species within a city. However, irrespective of city, both species were primarily kept for their financial functions whereby sheep were perceived as having higher economic value. Although breeding practices were very similar in many respects (low practice of castration, culling and replacement strategies, uncontrolled mating, no record keeping and selection criteria), the emphasis put on each selection criteria varied across cities and between species. Irrespective of city, most of the goats were of the indigenous type while keeping crossbred animals and/or maintaining more than one genotype in the same flock was more commonly practiced by sheep keepers. This points to a higher motivation for strategic breeding among sheep than goat keepers and indicates that the former might be interested in joining carefully designed participatory flock improvement programs.
