        1 - The Relationship between Body Condition Score and Milk Production, Udder Health and Reduced Negative Energy Balance during Initial Lactation Period: A Review

        Achieving improved milk yield from a healthy udder, with a minimum weight loss especially during initial lactation, is the aim of every dairy farmer. Body condition score (BCS) of dairy cows has been found to be significantly associated with body weight, milk performance and udder health status of dairy cow during the pre and post- partum period. Under and over body condition of dairy cows should be avoided. Both conditions lead to weight loss, loss of milk, poor udder health and metabolic disease in dairy animals. Cows should have balanced body condition before and after calving. Better management practices during the dry period and at calving may optimize production, and udder health in subsequent lactation. This review aims to highlight livestock management strategies during the dry period which may help in optimizing BCS at calving and during the subsequent lactation period, thus improving milk performance and udder health, and reducing weight loss in early lactation. تفاصيل المقالة

        2 - Community‐Based Productivity Veterinary Services Increase Smallholder Dairy Farms’ Income and Number of Cows for Breeding at Mymensingh of Bangladesh

        We reportedhere data from a productivity veterinary service that was participatory planned and delivered on farms at the Kanihari Union belongs to Mymensingh District of Bangladesh. We used a set of five forms and a breeding calendar on farm visit once in a month to guide service delivery and acquisition of data and to keep the records on general cattle health, reproduction, udder health and feeding management of the farms. Once information were entered into a database application, a summary sheet was produced, which was taken into the farm to guide the activities in follow-up visits. On average, 72% anoestrous cows and heifers resumed their estrous cycle and 64% of repeat breeding cows and heifers conceived when treated. When GnRH was injected at the time of artificial insemination (AI), 73% repeat breeder cows conceived. Sixty four percent cows recovered from mastitis and 87% sick animals recovered when treatment was given based on clinical diagnosis. Majority of clinically diagnosed diseases were endoparasitic infections (19.0%) and anorexia (11.9%).More than 80% farms that received the service had an income increase ranging from US $ 1.0 to $ 43.9 monthly per cattle. Productivity veterinary services increase farmers’ monthly income per cattle and number of cows for breeding. تفاصيل المقالة

        The periodic trimming of the long hairs growing at the distal end of the tail -switch trimming- is humane alternative of tail docking. The purpose of this study was to determine the influence of switch trimming on somatic cell count (SCC), California mastitis test (CMT) and udder cleanliness of lactating cows in a free-stall dairy farm. In the present study, 219 healthy, pregnant Holstein cows were enrolled. All cows were randomly allocated to either trimmed (T) (n=107) or control (C) groups (n=112) prior to entering the calving pen. The long hair in the tail switch of the cows enrolled in group T was removed completely by a hair clipper machine, while the tail hair of the animals enrolled in group C remained intact. After two months, all studied cows were evaluated for udder cleanliness and health. Udder cleanliness scores (UCS) were significantly associated with switch trimming of the tail (P=0.0129). Both trimmed and control cows showed significant difference in UCS of 2 and 3 (P≤0.05), though the difference in other UCS was not significant. No significant difference (P=0.41) in SCC between groups was identified. Comparing the CMT scores of front, rear, or all udder quarters showed that the frequency of a CMT score of 0 in group T was significantly higher than in group C (P≤0.05). Reversely, the frequencies of Trace and 2 scores of CMT for rear and all udder quarters in the control group were significantly higher than the group T (P<0.05). The results of this study show that switch trimming may be suggested to improve cleanliness and udder health of dairy cows in free-stall housing systems. تفاصيل المقالة
