Eight villages such as Mohonpur, Char Soydabad, Bonbaria, Satiantoli, Morgram, Khoksh abari, Kholishakura and Vatpiari of Sirajganj Sado rupazila under Sirajganj district in Bangladesh were selected for the study. Sirajganj district is situated between 24001' and 24047' north latitudes and between 89015' and 89049' East longitude. The temperature ranges from 34.60C t o 11.90C and annual rainfall is 1610 mm. Total 1152 Black Bengal female goats in which 936 adults (>1 year of age) and 216 growing (3 to 12 months of age) goats were selected for study. The research work was carried out from July 2013 to March 2014
Soundness examination: Before introduction to QF each goat was examined by Veterinarian and only healthy and sound goats were allowed to rear in QF for the study.
Housing management: Goats were kept under semi-intensive rearing systems. Goats were housed in a permanent wooden or bamboo floor house. Jute sack and rice straw or both were used as bedding when environmental temperature low (mainly during November to February) for all age groups of goats.
Feeding management: Feeding management of goats were based on green grasses from various sources such as green pasture grasses (Perennial grasses), weeds from paddy field, napier grass, khesari grass and varieties of leaves such as jackfruit leaves, mango leaves, banana leaves and small quantity of rice straw with supplementation of concentrates. The commonly used concentrate ingredients were wheat bran, sesame oil cake, rice bran, broken rice maize powder, matikali bran, common salt, vitamin, mineral but the proportionate use of these ingredients varies from farm to farm. Fresh drinking water was also supplied to the goats. Goats were kept under semi intensive condition. They were allowed to grazing on communal land in both seasons and stall fed in the remaining period of the day. When goats were kept in stall, feeds were supplied average 2.0 times in a day.
Herd health care: Goats were vaccinated against PPR and administered with anthelmintics at QF. Control measures against contagious ecthyma, pneumonia and diarrhoea were undertaken with appropriate drugs/measures. Regular vigilance was performed to ensure feeding, herd health care, proper breeding and cleanliness of the farm.
Disease diagnosis and data recording: The sick and death animal was measured daily on the basis of observed clinical signs and some by laboratory examinations. Suspected causes of mortality were clarified by taking history, clinical signs before death where showed, postmortem examination and in some cases by laboratory tests. After 16 days total numbers of sick, death and distributed goats were measured from each QF and this procedure was continued upto final distribution (up to 6th batch). Then morbidity and mortality rate was measured with formula.
Data were analyzed by using Chi-square test of fixed factor contingency table and student’s t-test.
