Abstract/ Executive Summary:

The study was undertaken with the objectives to determine the comparative production performance of dairy cows fed with untreated straw (S; T₀), untreated triticale straw (TS; T₁), urea-molasses triticale straw (UMTS; T₂), and urea molasses straw (UMS; T₃), to determine milk quality. A total of 20 lactating cows (L x F, SL x F, F-62.5 and F-75%) were divided into 4 treatment groups and the diets were supplemented with a concentrate mixture containing 20.83% CP as per requirement of individual milk production. The study reveals that the highest total DM intake (kg/day) was observed in (10.91 ± 0.09) S followed by UMS, UMTS and TS. The DM digestibility among the treatment groups were 66.08, 64.09, 69.36 and 65.20 for S, TS, UMTS and UMS, respectively. The CP digestibility was also significantly (P<0.05) higher (78.45) in UMS treatment group compared to S, TS and UMTS treatment groups and differences were significant (P<0.05) among the treatments. The highest average (7.35 ± 0.85 L/d) milk production was observed in UMS treatment group followed by UMTS, TS and S, respectively. The per cent increase in milk production was highest in UMS followed by UMTS, and TS, respectively. Therefore, it can be concluded that triticale straw has a great potential similar to rice straw in feeding of dairy cows.

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

To determine productive performances of caws fed fresh or urea-molasses treated triticale straw and its comparison with rice straw

Methodology:

A total of 20 lactating cows of different parity of cross-breds (L x F, SL x F, F-62.5 and F-75%) were selected from the Central Cattle Breeding and Dairy Farm, Savar, and all the experimental cows were divided into 4 treatment groups having 5 animals in each treatment group. The dietary treatments were untreated rice straw (S; T₀ ); untreated triticale straw (TS; T₁), urea molasses triticale straw (UMTS; T₂) and urea molasses rice straw (UMS; T₃) and all the treatment groups were allotted to a Completely Randomized Design. All animals were supplemented with a concentrate mixture containing 20.83% CP as per requirement of individual milk production. At the mid of the feeding trial, a digestion trial was conducted with 5 days collection period of fecal output on the same stall. During the digestibility trial, data were recorded on the daily amount of feed offered, residues left and faces voided. Similarly, daily samples of feed offered were obtained, ground and stored in the freezer for chemical determination. Dry matter (DM) content of as fed feed samples was determined once a week. Both the feed and feces samples were brought and analyzed for dry matter, crude protein (CP), crude fibre (CF), ether extract (EE), organic matter (OM) and ash content. All the collected data were organized and analyzed in an ANOVA of a Complete Randomized Design (CRD). Duncan’s Multiple Range Test was used to determine the significance differences among the treatment means.

Achievement/Findings:

The highest average (7.35 ± 0.85 L/d) milk production was observed in UMS treatment group followed by UMTS, TS and S, respectively. The per cent increase in milk production was highest in UMS followed by UMTS, and TS, respectively. Therefore, it can be concluded that triticale straw has a great potential similar to rice straw in feeding of dairy cows.
