Abstract: The purpose of the study was to establish the structure of monitored animal farms and determine reproductive parameters of Sahelian goats in the Guera Region, in Central Chad. Data were collected through longitudinal survey in 27 observatory farms during three years using goats identified by numbered ear tags. The herds were composed on average of about 71% of females. The age pyramid covering all years showed a significant number of males aged between 0 - 1 year and perceptible fall thereafter. However, some stability was observed in the class of the 2 - 8 years old among females. The frequencies of accumulated kiddings showed that 44% of births occurred in the rainy season against 28% respectively in the cool dry and hot dry seasons. Obtained reproduction parameters were: a sex ratio of 0.51 in favor of males, a kidding interval of 10.6 months with significant differences (P < 0.05) according to the rank of birth, an age at first kidding of 16.5 months for females born in monitoring and an age of 20.3 months for all first-kidding, giving an apparent fertility rate of 145%, a fecundity rate of 116% and an abortion rate of 2%. The composition and structure of herds have highlighted the importance of females to ensure the reproducibility of goat production systems. The determined reproduction parameters are references for actions to improve goat rearing in this area.

Abstract: The objective of the study was to assess zooeconomic parameters like age, weight, price and destinations of produced chickens that are sold on three main markets of Guera, east-central Chad. Data were collected over six months on the market places of Mongo and Mangalme and four months on the market place of Bitkine. The transversal and retrospective survey was coupled with direct observations and weightings. For 1549 marketed chickens, the males made up 57% and the females 43%. The average values per chicken were found to be 16.29.9 months for age, 1082.4371.2 g for weight and 1607.8FCFA 414.6 for price. Average age and weight of sold chickens were significantly higher (p<0.001) on Mangalme market, with an average price significantly lower (p<0.001). On the whole, 52% of surveyed chickens were intended for sale in the capital NDjamena, 39% in Mongo city, 7% in Bitkine and 2% in Mangalme. According to the final destinations declared by buyers, average age and weight of the sold chickens to be consumed in Bitkine were significantly lower (p<0.001) but with an average price significantly higher (p<0.001). The Mangalme sellers sold mainly old chickens in order to earn more money. The pressure exerted by NDjamena traders to purchase chickens in Bitkine increases prices.
