Evaluation of The Farmers’ Feeding Strategies on Growth Performance and Carcass Characteristics of Growing Pigs in Selected Areas of Morogoro Municipality

The objective of this study was to compare feeding strategies used by pig keepers in urban and peri-urban areas of Morogoro from different feed ingredients in relation to growth performance and carcass characteristics of growing pigs. The study had two components. Study I was a survey among 60 pig farmers in Morogoro. The results showed that feed resources mostly used by farmers were crop by products and poor non-conventional waste like kitchen waste and green forages. It was noted that major constraints to pig production in the study area were expensive feeds and availability of quality feeds. It was also revealed that the average disposal age of pigs was 11.96 ± 1.79 months with average weight of 67.09 ± 8.64. In study II 30 castrated pigs with average body weight of 12.77 ± 0.84 kg and aged two and half months were fed three experimental diets for 18 weeks at farmers’ homesteads. Pigs were randomly allocated to five selected farmers; and the three diets T1, T2 and T3 with two animals in each treatment. Pigs were weighed weekly before morning feeding. The average daily gains were 100 g, 400 g and 300 g for T1, T2 and T3 respectively. Their respective feed intakes were 0.5 kg, 1.60 kg and 1.20 kg, and their corresponding FCR were 4.60, 3.71, and 4.21.Their mean hot carcass weights were 13.40 kg, 30.20 kg and 23.80 kg for T1, T2 and T3 respectively. Total lean in half carcasses were 4.50 kg, 9.50 kg, and 7.50 kg for T1, T2 and T3 respectively. Costs of 1kg gain were 1522 TSh, 1583 TSh and 1158 TSh for T1, T2 and T3 respectively. In conclusion, T2 had better growth performance and better carcass characteristics in relation to lean meat while T3 had higher net return.
