The Livestock Nutrition Laboratory

Constructed in 2015 with funding from the East African Agricultural Productivity Project (EAAPP), the lab was completed and handover in February, 2016.

The lab is fully functional and handles a range of samples including;

  1. Livestock feeds including grasses, legumes, silage and concentrates
  2. Milk samples
  3. Meat samples

Genetic diversity of Theileria parva strains in Uganda: Implications for Muguga cocktail vaccine efficacy in ECF control

ECF causes high mortality (up to 100%) among exotic and crossbred cattle impeding the development of the dairy industry and poverty reduction among smallholder dairy farmers. ECF control depends on acaricides to kill ticks. Prolonged acaricide use has resulted into environmental contamination and emergence of acaricide resistant ticks (Vudriko et al 2016).

Goat breeding program

Development of elite indigenous goat lines with superior growth rates, twining ability, mature weights and reduced age at maturity.

Current Research Efforts to achieve desired targets

  • Established community goat breeding farmers’ groups through training and sensitisation
  • Ear Tagging, blood samples collection, create performance and pedigree data base through recording
  • Periodic participatory selection of elite young breeding bucks and exchange of bucks among farmers

Evaluation of Napier grass (Pennisetum purpureum) varieties for performance and tolerance to Napier stunt Disease in Uganda

Napier grass despite its high biomass production has been threatened by Napier Stunt Disease (NSD). NSD has the ability to cause over 70% biomass reduction.

Conclusion & Recommendation :

  • All varieties had a mean severity score of less than 3 showing that the varieties are tolerant to NSD under Ugandan conditions.
  • Variety 97, Kakamega2, 16702, 112 & Kakamega1 are recommended for multiplication and dissemination to farmers

Ngu-2B Tsetse fly trap for Karamoja AEZ

Trapping is a formidable tool for the  reduction  of  tsetse  fly population  densities  and associated  diseases  in  humans and  livestock.  High  densities  of tsetse flies in the Karamoja Dry land  Agro-ecological  Zone (AEZ)  of  Uganda  is  a  threat  to livestock  health  and  production due to direct and indirect losses.

Milk yield response of cows supplemented with sorghum stover and Tithonia diversifolia leaf hay diets during the dry season in northern Uganda

Introduction : Tithonia diversfolia (Mexican sunflower) leaves are high in Nitrogen (3.5%) concentration, which makes it a possible option for improving crop residues such as sorghum stover for livestock feeding (Chikuvire,2013).

Specific objective : Assess milk yield response of dairy cows fed a basal diet of Panicum hay and supplemented with on sorghum stover and T. diversifolia leaf hay based diets.

Supplementation improves growth rate  and reduces age at slaughter for grazing small East African Zebu Cattle (SEAZ)

Small East African Zebu (SEAZ) grow at a rate of 100g/day to 250kg LW in 5.5 to 6 years.

Major reasons include: Low quality and quantity of natural pastures (<3%CP and ~ 300g biomass per 1m2 area) and the natural grazing only system. This study sought to develop supplementary growth enhancing feed rations for SEAZ cattle under extensive grazing from locally available feed resource.
