Abstract

 

The aim of this trial was to assess the possibility of using teat perimeter in estimating milk production potential and kids’ growth rate in Nguni and Boer goats of South Africa. Traditionally, the productive capacity of goats doe, are judged to a large extent by the physical phenotypic characteristics. In this trial a 2 × 2 factorial  design (two goat breeds and two nutritional management systems) were used. Thirty six (36) recently kidded does (18 Boer goats and 18 Nguni goats) were also used in this experiment. The investigation was conducted between seven (7) and hundred (100) days post-partum. Half (n = 9) the Boer goat does and half (n = 9) the Nguni does were allocated randomly within breed to an extensive (veld) feeding treatment, and the other half per breed to an intensive (high energy) feeding treatment (this is traditionally practiced by profit driven intensive farmers). The results revealed that teat perimeter measurement could be used in both breeds under an intensive feeding regime. The results further revealed that in the extensive feeding regime, the prediction of milk potential through teat perimeter can only be carried out in the Nguni goat breed. These results indicate that the teat perimeter measurement can be used to measure milk production of the Nguni goats based on the two feeding systems. These results appear to suggest that teat perimeters in the Nguni goat could be the best tool for the resource poor farmers.
