“…Summary statistics for LW, HG and HW for adult and heifers for the various breed groups are given in Missohou et al 1997). The average LW, HG and HW measures for cows of high Bos Taurus found in this study were generally lower compared to 419-781 kg, 176-223 cm and 125-150 cm reported for Holstein Friesians cows in a developed country context (Yan et al 2009), likely due to the lower feeding level of animals in this study in comparison to that in the developed world, and because the high Bos Taurus group in this study were not always pure-bred (see Table 1).…”

We investigated the prediction of live weight (LW) of dairy cattle in low-to medium-input systems in Senegal, based on measurements of heart girth (HG) and height at the withers (HW). A total of 459 female dairy cattle, mainly comprising indigenous Zebu and their crosses with Guzerat or Bos Taurus, were weighed (kg), and their HG (cm) and HW (cm) determined. Farmers were asked to provide their own weight estimates for each animal. The single explanatory variable that explained the most variation in LW was HG. The best model to predict LW from HG for the overall data was LW = 4.81 HG − 437.52 with an adjusted R 2 of 0.85 and a root mean square error of 34.25 kg corresponding to 11.10% of the mean LW. This model predicted the LW of 91-100% of cows and 64-100% of heifers within 20% of their true-live weight, in the weight range of about 100-500 kg. In comparison, farmers could only estimate the LW of about a quarter of their animals within 20% of their true LW. This weight prediction equation, when translated into a weigh band, could provide a simple and reliable method for cattle keepers to estimate the weight of studied cattle breed types.

“…However, because of CRZ difficulties on data collection and herd management, these measurements have been gradually abandoned (Thiongane and Denis, 1974;Chollou et al, 1978;Sow et al, 1988;Sow et al, 1991). In rural farms, latest information was provided by Mime (1981), Pagot (1985) and Missohou et al (1997). In summary, recent morphometric informations on adult Gobra animals do not exist so it was not easy to compare our results.…”

“…The morphometric measurements for their part are lower than those available in the literature. Indeed, the study of Denis and Thiongane (1973) on zebu Gobra cattle enrolled in the CRZ of Dahra's breeding program, reported a HeW's average from 122 to 133 cm, Mime (1981) and Missohou et al (1997) described a HeW varying from 135 to 140 cm for the male and from 125 to 135 cm for the female. The sexual dimorphism with a marked superiority of males compared to females was early emphasized by Pagot (1985).…”

Gobra cattle; Centre de Recherches Zootechniques of Dahra; morphometric characterization; phenotypic characterization. Senegalese zebu Fulani (Bos taurus indicus), commonly called zebu Gobra, is one of three local cattle breeds. Its socioeconomic importance for food security and incomes generation was at the origin of the establishment of the Centre de Recherches Zootechniques (CRZ) of Dahra in 1952 and the initiation of the Gobra cattle breeding program. In order to increase knowledge on local bovine breed, this study aimed to phenotypical characterization of Gobra zebu. Twentysix (26) phenotypic parameters were measured or described on sixty-six adults animals (six males and sixty females) over 4 years of age chosen from the selection's nucleus herd of the CRZ. Also, weight records on the animals from 2010 to 2016 were also analyzed. Qualitative parameters were expressed as percentages and descriptive analysis were done on quantitative parameters. Means comparison according to the sex of animals was performed using Student's t-test or Wilcoxon test according on results of the Shapiro-Wilk normality test. The main results showed that Gobra cattle is an ellipometrical animal with an average height at the withers of 121.56 ± 5.53 cm, a heart girth of 171.39 ± 11.23 cm and a body length of 127.15 ± 11.29 cm. The body weight's average was 577.5 ± 81.32 kg and 393.81 ± 51.69 kg respectively for bulls and cows. Sexual dimorphism is marked between males and females with significant differences. Low weight performances are reported compared to previous studies in the same research station. Gobra breeding program needs to be reinforced and ex situ conservation should be considered.

“…These performances are constrained by the environment, indicating the poor availability and quality of fodder. Indeed, while local breeds might present genetically lower performances due to their adaptation to scarcity, several studies showed that the genetic potential of indigenous breeds might be better exploited by the adoption of simple husbandry techniques, relating to feeding and health follow-up, resulting in higher weight gains and milk yields (Achard and Chanono, 1997;Missohou et al, 1997;N'Djoya and Loko, 1997).…”

The present survey was conducted to characterize herding practices and overall production performances of pastoral systems in the Kanem region, Chad. Overall, 69 livestock keepers were interviewed, among which 12 sedentary agro-breeders, 35 mobile agro-herders, and 22 nomadic herders. Species association is a main feature of the herd structure. Agro-herders make most often an association between cattle and small ruminants (47%). Among mobile agro-herders, the association between cattle and small ruminants is frequent (47%) whereas nomadic herders tend to show more diverse modalities of herd composition. Feed is mainly based on natural pastures. However, complementary feeding is provided, targeting the producing females and weaker stock during the maximal risk period. During the rainy and post-harvest season, milk yields are significantly higher among agro-herders than in other groups (p<0.05). In camels, the season of the year and the herding system have no effect on milk production. Regarding reproduction parameters, the mean age at first calving is 4.7±0.7 years in cows and 5.8±0.6 years in she-camels. The calving interval is 1.9±0.4 years in cows and 2.7±0.4 years in she-camels. The fecundity rate is around 63% in cows and 44% in shecamels. Simple husbandry techniques might help increasing production levels to the benefit of the households, as complementary feeding, which is already provided in a targeted way. The systematic implementation of this complementation faces constraints of availability of these agricultural byproducts on the local markets. As far as research is concerned, the study recommends the implementation of herds monitoring of the area in order to precise the livestock breeding practice as well as zootechnical parameters.
