Abstract/ Executive Summary:

The study was conducted to determine the effect of triticale green fodder as replacement of straw or concentrate mixture by designing two experiments with the objectives to determine the optimum level of triticale green fodder as replacement of straw and concentrate mixture in straw based diet of dairy cows and milk production and quality & live weight changes. Homogeneous productive lactating cows of early lactation were randomly allotted to seven dietary treatments having five replications in each dietary treatment. The design of the experiment was organized in such a way that in one tail, four straw based diets which were supplemented with 0, 50, 75 and 100 % of triticale green fodder on DM basis and all the four diets were assigned to four treatment groups of lactating cows having 5 cows in each group. On the other tail, the concentrate portion of other three straw based diets were replaced by 50, 25, 100% triticale green fodder. It was concluded that triticale and straw at a ratio of 50:50 may be fed for better production performance of dairy cows. Moreover, concentrate mixture of a dairy cows may be replaced up to 75 % by triticale green fodder for better milk production of dairy cows.

Commodity: Fodder

Objectives:

To determine the optimum level of triticale green fodder as replacement of straw

Methodology:

The study was conducted at Central Cattle Breeding Centre and Dairy Farm under the Department of Livestock Services (DLS) in collaboration with Bangladesh Livestock Research Institute, Savar, Dhaka. A total of 35 (thirty five) lactating crossbred (FxDeshi) cows of similar lactation period and with average body weight ranges from 290.00 to 330.00 kg were selected for the trial. Homogeneous productive (group average milk production of animal varies from 4.54 kg/ h/d/ to 4.66kg/h/d) lactating cows of early lactation were randomly allotted to seven dietary treatments having five replications in each dietary treatment. The design of the experiment was organized in such way that in one tail, the design of experiment had four straw based diets which were supplemented with 0, 50, 75 and 100 % of triticale green fodder on DM basis and all the four diets were assigned to four treatment groups of lactating cows having 5 cows in each group. On the other tail of the experiment, the concentrate portion of other three straw based diets were replaced by 50, 25, 100% triticale green fodder. A digestibility trial was conducted at the mid of the experimental period to determine the digestibility of nutrients. Feed offered and feed refusal was recorded daily to determine voluntary DM intake. The proximate and other components of feed and fecal materials were done. The collected data will be analyzed through Completely Randomized Design (CRD) and analysis of variance will be done to determine the treatment effects. Collected data were analyzed statistically by using Compare Means (CM) procedure of One-Way Analysis of variance (ANOVA): Post Hoc Multiple Comparisons of SPSS 11.5 for Windows.
