Abstract
The objective of this study was to figure out the prevalence and probable causes of repeat breeding (RB) in dairy cows. Hence, a cross-sectional study was conducted on randomly selected 265 dairy farms in Sirajganj, Bogura, Rangpur, Satkhira, and Munshiganj districts of Bangladesh from December 2018 to February 2019. Data were collected through a direct interview method using a survey questionnaire. The reproductive organs of repeat breeder cows were examined for pathological, infectious, and functional reasons, and genital tract abnormalities. Additionally, the influence of nutrition, season, and age on the frequency of RB was recorded. The prevalence of RB was 28% among the 3824 cows investigated. Among the total repeat breeder cases, 72.54% of RB cases were found in Holstein-Friesian crossbred, 23.90% in Jersey crossbred, 1.50% in Sahiwal crossbred, and 2.06% in indigenous cows. The prevalence of RB was significantly highest (P < 0.01) in Satkhira (44.35%) and lowest in the Munshiganj district (15.87%). Data indicated that a major proportion of cows significantly (P < 0.05) faced RB problems due to functional causes (34.18%), followed by pathological causes (28.01%), genital tract abnormalities (21.32%), and infectious causes (16.49%). Furthermore, the cows were remarkably (P < 0.001) affected in RB during the summer season and nutritional deficient diseases like milk fever (70%). Age (3-7 years) had a significant (P < 0.001) effect on the RB occurrence (90%) in crossbred cows. However, particular focus should be given to systematic breeding, balanced nutrition, artificial inseminator efficiency, and hygienic inseminating tools to reduce RB incidence in high-yielding crossbred cows.

Abstract
Six indigenous Bangladeshi Garole sheep (Ovis aries) (BW: 8±0.5 kg; Age: 1yr) were divided into two groups using a randomized block design to investigate the effect of total mixed ration (TMR) pellet feeding on growth parameter, blood metabolomics, carcass and meat characteristics. Control diet was composed of road side grass, rice straw, wheat bran, mustard oil cake, molasses, common salt which considered as loose total mixed ration (L-TMR) and treatment diet was pelleted form of L-TMR (P-TMR).In both the dietary treatments the animals were fed at 1.5 times of maintenance energy and protein requirement. P-TMR revealed a positive impact (p < 0.05) on live weight gain and feed conversion ratio than L-TMR. Total digestible nutrients (TDN) and digestible crude fibre (DCF) was significantly higher (p < 0.05) in P-TMR group whereas there was no significant difference (p < 0.05) in other digestible nutrients as well as plasma metabolites like plasma glucose, triglyceride, total cholesterol, HDL-cholesterol and LDL- cholesterol concentration between two dietary group. Dressing percentage and eye muscle area was significantly higher (p < 0.05) in P-TMR group but no significant difference was found between dietary treatments in term of disposition of body fat, proximate composition of mutton, all the sensory parameters except tenderness and overall acceptability. So, it could be concluded that, the P-TMR might be fed to sheep for better growth performance and higher meat production rather than production of functional mutton.Progressive Agriculture 28 (3): 222-229, 2017
