Abstract/ Executive Summary:

Dairy farmers (82.9%) had no idea about genotype, quality & merit of bull semen being used. Almost 55.1% lactating cows were suffering from sub-clinical mastitis (SCM). Cows with 75% Holstein inheritance experienced more SCM (63.0%) than others. Draminski mastitis detector was effective for diagnosis of SCM in dairy cows. Neomastipra-JR5 as intra mammary infusion against SCM in lactating cows was found effective (78.2%). Application of some modalities and management tools significantly reduced mastitis (11.76% SCM) occurrence in dairy cows. Using towel for cleaning udder with antiseptic potassium permanganate in luke warm water without introducing calf with udder before and after milking and /or use of plastic mat in the floor of lactating cows were very effective in mastitis control. Evaluation of genotype x environment interaction indicated that for reproduction 50% HF crossbred cows and for production both 50% and 62.5% HF crossbred cows would be suitable for use in small holder peri-urban dairying system. Using herd book based pedigree and performance records (test-day milk records of registered cows and reproductive profile of their mothers, own body weight, growth and health information) a total of 24 young seed bulls in two batches (16 plus 8) were certified and recommended suitable by the Seed Certification Committee for use in breeding to gear smallholder dairying. Information catalogues were disseminated among the cattle breeding service providers of the country (both government and private sector). Finally, replication of this Herd Book based farmer participatory pilot research cum development work elsewhere in the country by cattle breeding service providers of Bangladesh (DLS, Milk Vita, BRAC, Lal Teer) is envisaged.

Location: Bade Kolpa of Khagdahar and Chalakandi of Boyra in Mymensingh Sadar of Mymensingh district and (ii) BAU, AI Centre, Mymensingh

Start Date: 01-04-2010

End Date: 31-12-2013

Program Area: Animal Health and Management

Commodity: Bullock

Objectives:

1. To develop a science-led farmer participatory system for seed bull production and 2. To ensure supply of meritorious and clean seed bull to the dairy industry of the country.

Methodology:

In this project research was carried out to establish Herd Book recording system for the production of meritorious breeding bulls in close cooperation with the cattle raisers of the project area. Farmer participatory Herd Book recording system, developing milk recording and genetic evaluation system, identification of young seed bulls, progeny show, preferential mating plan and replacement of AI breeding males with superior ones on regular basis for use in the farmers’ herd were the main features of the project. However, the project methodology included the following steps : i) Baseline Survey, ii) Identification of Superior Cattle Genetics in Project Area (crossbred vis-à-vis indigenous), iii) Farmer Consultation and Contractual Agreement with Elite Farmers, iv) Farmers’ Need Assessment and National Workshop, v)Opening Herd Book and Registration of Elite Cows, vi) Farmers’ Training, Routine Deworming and Vaccination Program, vii)Breeding Through AI Using Superior Dairy Genetics (crossbred / indigenous), viii)Calf Identification and Registration, ix) Milk Recording, x) Animal Database Management and Genetic Evaluation, xi) Identification of Superior Young Bulls (crossbred / indigenous), xii) Testing Young Bulls for Diseases and Breeding Soundness , xiii) Organizing Progeny Show, xiv) Certification for Meritorious Young Seed Bulls and xv)Seed Bull Offer Among Cattle Breeding Service Providers.
