Abstract/ Executive Summary:

The effect of feeding maize-based concentrates on milk yield in cows with cost-benefit analysis was done at smallholder farms in four districts of northern Bangladesh. Concentrate mixtures containing wheat bran, rice polish and sesame oil cake were supplied to 40 indigenous (Desi) cows (20 in Group A and 20 in Group B) for 30 days before intervened feeding. Cows were given 1 kg maize-based concentrates/100 kg body weight twice daily for a further 60 days after feeding intervention. Cows’ body weight, milk yield and farm income were recorded before and after maze-based concentrate supplementation. Milk production is increased by 30% for Group A and 90% for Group B. The difference in milk yield before and after supplementation of maize-based concentrate in Group B was significant (P<0.05). The cows’ average body weights in Group A increased by 4.7 kg and in Group B by 1.8 kg. In both groups, net income increased and the income increase in A was significantly (P<0.01) greater than in B. Maize-based concentrated feeding in cows led to better milk yield with good economic return.

Objectives:

1. To measure the effect of supplementary maize-based concentrate feeding on milk yield of indigenous cows under village conditions and the cost-benefit analysis.

Methodology:

Location and animals - This study was conducted in four districts of northern Bangladesh between April and June 2009. A total of 40 indigenous cows (10/district) were selected from 40 farms. Farms had a mean of 4.5 animals with 1.1 lactating cows. The age of the cows ranged from 4 to 5 years and their parity from 3 to 5. Body condition score (BCS) ranged between 2.5 to 3.0 and body weights from 110 to 160 kg. All animals had been lactating 2 to 4 months. The animals were in two groups: Group A (20 cows: 10 from Sirajgonj and 10 from Joypurhat) and Group B (20 cows: 10 from Gaibandha and 10 from Rangpur). Experimental procedure - In both groups, the animals were fed basal roughages (straw and green grass) with concentrates (1 kg for 100 kg body weight) made of rice bran, wheat bran, sesame oil cake, molasses, common salt and vitamin-mineral premixes for 30 days before feeding intervention followed by 60 days fed basal roughages with concentrates only after replacing of wheat bran by maize grain after feeding ntervention. Concentrated feeds were given twice daily. One kg concentrated feed was provided per 100 kg body weight, and ad libitum water. The cows were milked twice daily with their calves at foot. Both groups were maintained under identical management. Data collection and statistical analysis - Data were recorded for 30 days before feeding intervention and 60 days after maize-based concentrate supplementation. Daily milk yield was recorded. Changes in net income before and after intervention were calculated to make the cost-benefit analysis, determined by the formula {Income from milk (milk production × milk price) – milk production cost (feed intake × feed cost)}. Body weight of the animals was estimated according to the Shaeffer’s formula. The basal roughage and concentrate supplements were analysed for proximate principles and fibre fraction was analysed. The data were entered into Microsoft Excel work sheet and exported to SPSS (Version 10.0, 1999) for analysis. Descriptive statistics were computed and Paired t-test was done to detect the changes in milk production, body weight and net income per cow per day after supplementary feeding.

Achievement/Findings:

Maize-based concentrated feeding increased milk production and net income. The maize-based ration proved cost-effective in promoting milk production in small dairy farms.
