The effects of doe breed on reproductive rates and internal parasite tolerance

Li Wang, Tennessee State University

Abstract

Boer (n= 60), Kiko (n= 89), Myotonic (n= 55) and Spanish (n= 92) meat goat does were studied to assess potential breed effects on reproductive performance and health. The herd was semi-intensively managed on humid subtropical pasture in central Tennessee for three years. This study was conducted after the herd was rebuilt following a flood. Body weight of Boer and Kiko were heavier (p< 0.01) than Spanish, which was heavier (p< 0.01) than Myotonic doe. At kidding, Kiko and Spanish delivered heavier (p< 0.05) litters than Boer and Myotonic does. Boer does weaned lighter (p< 0.05) litters than Kiko, Myotonic and Spanish; the latter three were similar. Litter weights of single kid litters were lighter than for multiple kids litters at kidding and weaning (p< 0.05). Reproductive and survival rates of Myotonic were lower (p< 0.05) than for Kiko and Spanish, while higher (p< 0.05) than for Boer does. Myotonic doe fecal egg count (FEC) was lower (p< 0.01) than for Boer and Kiko does. Spanish were lower than Boer, but similar to Kiko and Myotonic does for mean FEC. Fecal egg count of 2-year-old dams was lower (p< 0.05) than 7+ years old dams. Packed cell volume (PCV) of 2-year-old does was higher (p< 0.01) than 4 to 7+ years old does. Boer had lower (p< 0.01) PCV than Kiko, Myotonic and Spanish does. The latter three were similar. Kiko, Spanish and Myotonic does showed advantages compared to Boer for traits of reproductive performance and internal parasitism.^
