Abstract/ Executive Summary:

The present study was carried out to evaluate the effect of sire and environment on growth performance of grade-2 Brahman calves. A total of 70 grade-2 Brahman calves produced from 6 sires (14BR0043, 7BR-524, 14BR0040, 7BR-527, 14BR0041,7BR-522) were included in this study to know the effect of different sires on calves growth performances those located on 8 different areas (Barisal, Chattogram, Dhaka, Khulna, Mymensingh, Rajshahi, Rangpur, Sylhet). Analyses were performed by using Statistical Analysis System (SAS) version 9.1.3. Analyses revealed that sires had significant effect (p<0.05) on 1month, 6-month, 24-month weights and average daily gain. In contrast, non-significant effect (p>0.05) was observed on birth weight, 3-month, 9-month and 12-month weights of progeny. The highest mean birth weight (32.27±0.59 kg) and 1-month weight (57.58±2.11 kg) of calves was found from the sire 14BR0040 and 14BR0041, respectively. The highest mean of 3-month (81.57±3.13 kg), 6-month (186.71±6.20 kg), 9-month (332.43±8.07 kg), 12-month (463.57±13.61 kg) and 24-month (903.33±16.71 kg) weights were found by sire 7BR-524, 14BR0043, 14BR0043, 7BR-524 and 14BR0040, respectively. The area significantly (p<0.01) affected on 3-month and 6-month weight of calves. The highest 3-month weight (90.00±7.52 kg) and 6-month weight (184.06±3.79 kg) of calves were recorded in Barisal and Rangpur, respectively. The average daily gain (ADG) of progeny from birth to 6-months had been significantly (p<0.01) influenced by different areas. The strong positive correlation between ADG from 12 to 24 months and ADG from 0 to 24 months was 0.91. This result showed that the sire and environment had significant effect on above growth traits at different ages of Brahman progeny, which indicated that best sire in best environment can produce superior progeny. As Brahman breed are good meat producer and the average daily gain is quite satisfactory in the specific location so it is concluded that Brahman breed can be a valuable alternative approach for increasing meat production. However, further study with large sample size of grade-2 Brahman should be taken to increase beef production.

Location: The Central Cattle Breeding and Dairy Farm and 12 different upazilas (Barisal Sadar, Chhagalnaiya, Tungipara, Jashore Sadar, Dewangonj, Belkuchi, Sariakandi, Chowhali, Pirganj, Chirirbandar, Takurgaon Sadar, Moulovibazar Sadar) those were in 8 divisions (Barisal, Chattogram, Dhaka, Khulna, Mymensingh, Rajshahi, Rangpur, Sylhet).

Program Area: Animal Health and Management

Commodity: Calves

Objectives:

To evaluate the effect of Brahman breeding bulls on progeny early growth performance and phenotypic correlations among the growth traits at different ages of Brahman crossbred calves.

Methodology:

The present study was conducted with grade-2 Brahman calves cherished in different farmers’ level of 12 different upazilas of 11 different districts of 8 divisions of the country under the control of Department of Livestock Services (DLS) and Department of Animal Breeding and Genetics, Bangladesh Agricultural University, Mymensingh. Site of the experiment and period: This study was conducted at Central Cattle Breeding and Dairy Farm and 12 different upazilas (Barisal Sadar, Chhagalnaiya, Tungipara, Jashore Sadar, Dewangonj, Belkuchi, Sariakandi, Chowhali, Pirganj, Chirirbandar, Takurgaon Sadar, Moulovibazar Sadar) those were in 8 divisions (Barisal, Chattogram, Dhaka, Khulna, Mymensingh, Rajshahi, Rangpur, Sylhet) during the periods of January 2018 to March 2019. The entire activities of this experiment were performed with the collaboration of DLS and Department of Animal Breeding and Genetics of Bangladesh Agricultural University, Mymensingh through execution of a project entitled “Genetic improvement of indigenous cattle for beef production through crossing with Brahman cattle by farmers’ participatory breeding approach in Bangladesh” under the financial support from NATP. Source of data on 75% Brahman calves: In this experiment, the grade-1 Brahman heifers were taken which were produced from indigenous cows inseminating by Brahman (100%) frozen semen and then grade-1 Brahman cows were inseminated by 100% Brahman frozen semen to produce the grade-2 Brahman calves. Performance of those grade-2 calves were evaluated at different farmers’ level. A total of 70 grade-2 Brahman (75%) calves were included in this experiment of which 39 males and 31 females’ calves. All data such as date of artificial insemination, date of calving, weight of different growth stages was collected from the herd book recorded in Upazila Livestock Office with the help of community research assistants in the respective selected research areas of DLS with its ongoing project. Mating plan: In this experiment, the Local and G1 heifers (Brahman×Local) were inseminated by imported frozen semen of 6 different proven sires of Brahman breed for producing grade-2 Brahman progeny and measuring their growth performance at early stage. Measurement of weights: Birth weight, one-month and three-month weights were measured with a balance and six-month, nine-month, twelve-month and twenty-four month weights were calculated according to Shaeffer's formula as described by Hossain and Akhter (1999). Statistical analysis: The growth traits studied in this experiment for measuring the progeny performance were- birth weight, one-month, three-month, six–month, nine–month, twelve–month and twenty four–month weight as well as average daily gain at different stages. The significance of fixed effects was tested by least-squares analyses of variance using generalized linear model (GLM) procedure of the Statistical Analysis System (SAS, 2009). Mean comparisons were estimated by Duncan’s multiple range test (DMRT) method. The following generalized linear model was used for analyses: Y_ijkl=μ + S_i+ A_j+ X_k+ S_i*A_j+ e_ijkl,Where, Y_ijkl= Observation on traits; μ = Overall mean; S_i= Effect of Sire; A_j= Effect of area; X_k= Effect of sex; S_i*A_j= Interaction effect of sire by area and e_ijkl= Residual error.

Achievement/Findings:

The effect of sire and environment on progeny growth of grade-2 Brahman calves using the growth performance data of those calves will be helpful to find out the best genotype for beef production and to make decision for beef breeding. The higher significant weight of growth traits observed from different sires indicate that Brahman cattle has the ability of higher growth rate and building up greater final body weight with excellent body conformation and size. The significant effects (p<0.01) of area on three-month and six-month weight of calves indicate that weight of grade-2 Brahman calves can vary due to change in different areas. The strong positive phenotypic correlation point out that selection for growth traits will help to increase growth yield at following generation. The findings of this study indicate that grade2 Brahman crossbred can be a valuable stock to improve meat production and to produce a superior beef breed in Bangladesh. However, due to being a newly introduce breed in Bangladesh, Brahman cattle should be taken into consideration for further in depth study with large number of animals.
