The production performance and economic viability of Khaki Campbell ducks in backyard farming systems at NICRA-adopted flood-prone village in the Darrang district of Assam was evaluated. The study investigated key productivity metrics such as egg production, growth performance, and survival rates, in addition to economic factors like input costs, labor requirements, and market returns. The findings of the study indicated that Khaki Campbell ducks can perform well in backyard systems, with good egg production and growth rate. The mean body weight at 30 weeks of age was 1.82 kg and the average age at first egg was 163 days. Throughout the study period, the mean egg production was 185.5 and the mean mortality rate was 12.5%. The practice of backyard rearing of Khaki Campbell ducks is viable with a Benefit-Cost ratio of 2.07. The research highlighted the potential of ducks in enhancing household income and nutritional security and contributing to greater agricultural resilience against climate variability. The findings of the research contribute to the broader discourse on sustainable rural development and offers practical recommendations for similar agro-climatic regions facing the dual challenges of agricultural productivity and climate change

Cost of feed is one of the primary stumbling blocks for goat farming in Malaysia. Stage feeding was introduced as a method to formulate feed at minimum cost based on the requirement of different stages of production to improve overall farm productivity. A study was conducted to evaluate 5 feeding rations formulated based on the requirements of different production stages on Katjang-Boer crossbred. Ration formulated of creep feed (CF) for a period of 101d, starter grower (SG) (70d), grower finisher (GF) (98d), flushing feed (FF) (97d) and maintenance feed (MF) (155d) were compared with commercial feed (CCF and CMF) as control. Results showed a significantly higher (P<0.05 preweaning bodyweight of 12.83 ± 3.61 kg in CF at 101 days of age. Post weaning also achieved significantly higher bodyweight (P<0.05 of 22.20±2.78kg and 31.5±4.67 in SG (223 days) and GF (361 days) of age respectively. Feed cost per kg gain obtain in CF (RM5.68), SG (RM9.03) and GF (RM6.57) were lower compared to CCM of RM6.14, RM10.27 and 12.99 respectively. FF showed a significantly higher (P<0.05) average daily gain (ADG) of 67.01 ± 14.42 g while MF was able to maintain body weight at minimum cost. Stage feeding proved to be able to meet nutritional needs through significantly higher body weight in CF, SG, GF and FF as well as lower feed cost per kg gain rendering it as a more economical option.
