Abstract/ Executive Summary:

The study was conducted to find out the effect of the beef cattle diet on the performance of upgraded Holstein Friesian bulls at BAPARD cattle farms in Bangladesh. For this purpose, twelve Local x Holstein- Friesian upgraded bulls (L×F) of average 20 months of age and 213 kg live weight were divided into three equal groups. Three different diets such as (i) a mixed concentrate ration (T₁), (ii) mixed concentrate ration and UMS at a ratio of 1:1 on DM basis (T₂) and (iii) green Grass-based ration without concentrate and UMS. The results found that the average daily live weight gains of the three groups were 350g, 330g and 340g respectively, which did not differ significantly (P<0.05). Daily DM intake was significantly higher in T3 but the digestibility found lower than other treatments. In the case of feed conversion ratio (FCR), the highest FCR was found in T₁ (2.96) but the cost of per kg live weight gain was the lowest in T₃ (BDT 90) compared to T₁ (BDT 140) and T₂ (BDT 142). Therefore, considering the FCR and cost of per unit beef production, a beef diet of green grass might be the appropriate diet for the floodplains area for Local x Holstein-Friesian upgraded bulls.

Location: BAPARD Cattle Farm in Kotalipara, Gopalganj, Bangladesh

Start Date: 00-09-2019

End Date: 00-12-2019

Program Area: Animal Health and Management

Commodity: Feed, Cattle

Objectives:

To determine the i) growth rate of upgraded bulls with different formulated diets, ii) FCR of upgraded bulls with different formulated diets and iii) cost of meat production of upgraded bulls with different formulated diets.

Methodology:

The study was conducted at BAPARD Cattle Farm in Kotalipara, Gopalganj, Bangladesh for a period of 4 months from September 2019 to December 2019. The animals were selected and bought from the Cattle Breeding and Dairy Farm, Bogra under DLS (Directorate of Livestock Services). Twelve F₁ Local × Holstein- Friesian upgraded bull of almost 20 months of age and an average bodyweight of 213 kg were selected from the breeding herd. At the beginning of the experiment, the animals were weighed in the morning before offering any types of feed by using Shaeffer’s formula and the measurement was continued throughout the experiment in the morning once weekly. These 12 bulls were randomly distributed into 3 groups for 3 different formulated diets (treatment) and each group consists of 4 bulls (replication). Animals of group A were supplied concentrate mixture (T₁), animals of group B were supplied urea molasses straw with concentrate mixture (T₂), and animals of group C were supplied various green grass viz. sweet jumbo, Napier pakchong, red pakchong and local green grass (T₃) which were produced in BAPARD campus. The proportion of feed ingredients for the concentrate mixture was selected to fulfill the nutrient requirements of the experimental bulls. Individual records of these upgraded bulls were kept with separate feeding and watering system at BAPARD cattle farm in Kotalipara Upazila, Gopalganj, Bangladesh. All upgraded bulls kept under quarantine for 14 days period prior to fattening and then dewormed with anthelmintics before the starting of the feeding experiment. Antiworm 1 bolas was applied for 41-70kg body wt. to all of the upgraded bulls and a sufficient amount of water was supplied during this period for better effectiveness of that drug. Firstly, all the ingredients were measured using manual balance and kept in a safe place for feeding the animals. The required amount of urea, molasses and rice straw following the ratio of 3:15:82 on a dry matter basis (Khandakar and Reza, 1993) were weighted and kept separately. The weighed amount of urea and molasses was dissolved in water (55% of the weight of fresh straw) and mixed thoroughly in a container and a half of the total volume was sprayed on the total weighed amount dry and chopped straw kept spread on a polythene sheet, mixed thoroughly and turned completely upside down. The rest of the solution was sprayed on the straw and mixed thoroughly again without allowing any seepage of the urea molasses solution. The UMS was prepared as and when it was required and kept on a concrete floor covered by a polythene sheet to protect from the sun or rain for feeding the bulls. The formulated diets were fed ad libitum and calculated the total DM intake of the diets of the respective dietary components was maintained throughout the feeding period. The animals were fed twice daily once at 7.00 h and again at 15.00 h. Clean and fresh water was offered twice daily to all animals. The same amount of mineral supplements (di-calcium phosphate and salt) was supplied to all treatment groups to minimize mineral deficiencies. Daily feed offered to and refused by an individual animal was recorded and the animals were weighed every seven days for a total period of 120 days including a seven days digestibility trial after sixty days of growth trial. The obtained information was collected, stored and coded accordingly using Microsoft Excel-2013 to WASP- 1.0 (Web Agri. Stat Package) by ICAR (Central Coastal Agricultural Research Institute) for analysis. The results were expressed in body weight gain with P value for the Chi-square test. Significances were determined when P<0.05.

Achievement/Findings:

It may be concluded from the study that the cost per unit of beef production was the lowest in green grass-based feed formulation (T₃). Although the DM intake was higher and digestibility was lower in T₃, it seems to be profitable for the rural poor who were engaged in beef fattening. Concentrate feeds ingredients were expensive and UMS preparation was found difficult for the rural poor. Therefore, considering all of these factors green grass-based beef fattening was found suitable in this rural area.
