Abstract: Indigenous breeding practices of the farmers and the livestock production system form the bases for designing community-basedbreeding programs. The aim of this study was to characterize production system and examine breeding practices of the indig-enous goat farmers in Hai district in Northern Tanzania to determine their relevance in establishing a community-based breedingprogram in the area. A cross-sectional survey was conducted in which information was collected from 160 households randomlyselected from 6 villages. Average household herd was 29.2 goats with majority keeping less than 20 goats. Major reasons forkeeping goats were income generation, meat and milk production. Controlled mating was practiced mainly using apron andcastration. Castration was practiced using traditional methods to control breeding and improve meat quality. Farmers in the studyarea had large goat flocks and a small buck to doe ratio. Farmers do not have a good understanding of inbreeding and its negativeeffects but practise other good breeding methods which could impact the productivity of their animals. Diseases and feedshortages were the main constraints to production. Opportunities exist for a community-based breeding program to geneticallyimprove goat productivity. |

This experiment was carried out to analyze the tillering dynamics of the species Panicum maximum cv.
Mombaca subjected to three post-grazing heights: residue of 30 cm (30); residue of 50 cm (50); and residue of 50 cm during
spring and summer, lowered to 40 cm in the first fall season grazing and to 30 cm in the following grazing cycle, resuming
to 50 cm after the first grazing of the following spring season (50-30). Grazings were initiated whenever the swards intercepted
95% of the incident light. The post-grazing heights were allocated in the experimental units in a completely randomized block
design with three replications. The density of basal tillers did not vary between the residual heights evaluated. Swards managed
with variable residual height (50-30) presented higher rates of appearance and mortality of basal tillers during the summer
of 2007, indicating high tiller renovation. Regardless of the post-grazing height evaluated, lower rates of appearance of basal
tillers were found in the spring of 2006. The stability index of guinea grass cv. Mombaca was close to 1.0 throughout the
experimental period. Swards managed with variable post-grazing present structural changes able to improve the regrowth vigor,
which may be important to maximize the use of the forage species in the production system. |
