A zootechnical follow-up was conducted in Gounaka (Tassaoua department, Maradi region) in Niger on 48 goats aged less than one year to 4 years including 36 Redheads (75%) and 12 Blacks (25%), all followed by 76 kids including 37 females and 39 males of Red dress (58 individuals) and Black (18 individuals) belonging to 45 breeders. Analyzes have shown that frequency of single litter in Red goats (45.71%) was lower than that of Black (50%). On other hand, double litters were more frequent in Red goat (54.28%) than Black (50%). Differences in 2 cases of litters were not statistically significant (p> 0.05). There was a statistical difference (p <0.05) between milk production average of two types of goats. Red goat had regularly higher than Black at all rows of lactation. Average of durations of intervals between 1st-2nd, 2nd-3rd, 3rd-4th, 4th-5th and 5th-6th parturitions in Red and Black goats in all dresses were respectively 8.36 ± 1.56; 8.67 ± 1.49; 8.66 ± 1.34; 10.00 ± 0.82 and 9.50 ± 0.71 months without statistical difference. At birth, Black kids weighed more than their Red counterparts with 1.67 ± 0.20 and 1.61 ± 3.55 kg respectively, but difference was not significant. As for mean of decadal scrotal circumference (perimeter), it increased from first (D1) to tenth (D10) decade respectively from 5.13 ± 0.89 to 10.71 ± 1.61 cm for Red kids and 4.70 ± 0.80 to 9.51 ± 2.14 cm for black kids significantly (p <0.05).
