Ovarian Follicular Development Study in Jersey Crossbred Cows Reared in India

Ovarian follicular wave pattern studies provide the basis for applying reproductive intervention for improving fertility and improving the success of embryo transfer programmes in cattle. Four apparently healthy non-pregnant, pluriparous crossbred Jersey cows reared in a local farm located at Tirupur were utilized for this study. The evaluation was performed more than one plane, and all the measurable follicles (>3mm) were counted and recorded every other day. Various follicular dynamics related parameters were studied such as day of wave emergence, dominant follicle, static phase of dominant follicle, regressing phase of dominant follicle, day of maximum diameter, maximum size, duration of growth, growth rate, duration of atresia, rate of atresia and duration of detection. The Ultrasonographic evaluation was performed every other day throughout an estrous cycle starting from observed estrus (Day 0) to the subsequent standing estrus. A total of 10 normal estrous cycles were monitored for follicular wave pattern, in which 8 out of 10 (80 per cent) were two wave and 2 out of 10 (20 per cent) were three wave estrous cycles. The mean length of 2-wave estrous cycle was 19.25±0.41 days and 3-wave estrous cycle was 21.50±0.50 days. It was concluded that Jersey crossbred cows frequently had 2 wave estrous cycle with pre-ovulatory follicle size 12.62±0.94mm with the growth rate of 1.13±0.12mm/day and the size of pre-ovulatory follicle in 3-wave estrous cycle was lower (10.75±1.25mm) than 2-wave estrous cycle.

Characterization of Postpartum Ovarian Follicular Development Pattern in Crossbred Cows

Background: The postpartum period is crucial for cattle reproduction. The length of postpartum anestrus significantly impacts reproductive efficiency. Apparently enhanced energy attribution to milk production may lead to anestrus by delaying the onset of follicular activity. The absence of an ovulation stimulus, rather than insufficient follicle growth, determines the limited duration until ovulation. The current study was aimed to document the postpartum ovarian dynamics in crossbred Jersey cows. Methods: The study was conducted in ten postpartum crossbred Jersey cows. Transrectal ultrasonography was performed to record the follicular development pattern from parturition till two ovulation or 90 days postpartum on alternate days. The data was analyzed for follicular wave emergence, no of follicular waves, size of the dominant follicle and ovulatory status. Result: Fourty per cent of crossbred Jersey cows showed cyclicity and rest 60 per cent of cows are in anestrum. The mean diameter size of the dominant follicle in ovulated cows is 12.2±1.2 mm and in anestrum cows is 10.6±0.4 mm. The first wave emergence is 5.7±0.3 and 10.8±5.9 day in OV and NOV group respectively. In conclusion significant difference could be observed in emergence of first, second, third, fourth and fifth follicular wave emergence, growth phase duration, rate, size of the dominant follicle and duration of wave between postpartum ovulated and anestrum cows.

Relationship of Temperament during Milking with Milking Behavioural Features, Milk Yield and Udder Health of Crossbred Jersey Cows in Tropical Climate

Background: Milking behaviour of milch cows has notable impacts on their production efficiency. The present investigation is designed to explore the relationship of temperament while milking with other milking behavioural features, milk yield and udder health in crossbred Jersey cows. Methods: The study was done on crossbred Jersey cows (N=94) kept at ICAR-National Dairy Research Institute, Eastern Regional Station, Kalyani, West Bengal. The cows’ temperament score (TS) was judged on 5 points scale (1-docile, 5-aggressive). Calmer cows (TS-1 and 2) covered relatively higher (75.24%) proportions and no observation had shown for TS-5. Result: The temperament score was positively associated (P less than 0.01) with stepping/milking (0.72), flight speed (0.43) and exit score (0.33), while it was negatively associated (P less than 0.01) with milk yield (-0.64), milking duration (-0.61) and milk flow rate (-0.65). It was concluded from the above study that milking behavioural features are directly correlated with each other and production parameters. Dairy animals of calmer temperament were significantly high-yielders. The temperament of dairy animals did not significantly impact udder health as assessed through MCMT and somatic cell counts in milk.

Evidence Based Approach for Midcycle Estrum in a Crossbred Jersey Cows

Background: Effective and correct estrus detection determines the successful Artificial Insemination (AI) and in turn acceptable performance in dairy cows. All cows presented with estrus signs for AI are not usually fit for breeding for which mid cycle estrum (MCE) is one of the major causes that must be ruled out to prevent unnecessary AI and thereby preventing economic loss to the farmer. Methods: The present study was designed to compare reproductive parameters of True Estrum (TE) and MCE in crossbred Jersey cows. Around 24 cows addressed for AI has been randomly selected for the study. Based on history, clinical signs and ultrasonographic examination the cows were divided into two groups TE (n=12) and MCE (n=12) and assessed for their qualitative and quantitative parameters. Result: No significant difference could be observed between TE and MCE cows in expression of estrus signs. The size of the corpus luteum (CL) was significantly larger in MCE cows. In conclusion, no ovulation will occur in MCE cows, hence cows addressing with estrus signs needs to be ruled out for prominent CL ( greater than 15 mm) and relaxation of cervical internal os before AI.

Surgical Reconstruction of Perineal Laceration in a Crossbred Jersey Cow

A 6-year-old Jersey × Holstein Friesian cow was presented with history of vulval tear due to improper handling of dystocia by the owner. The foetal membranes were hanging from the vaginal canal through vulval tear. Clinical examination revealed all physiological parameters were within the normal range. Obstetrical examination revealed extensive tear from the caudal vagina up to vulva and the fetal membranes were hanging from both vulval passage and through tear in the vulva. The reconstructive surgery was performed under epidural anaesthesia. Post-operatively the animal was treated with Inj. Calcium borogluconate 450 ml i.v. besides Inj. Ceftriaxone at 20mg/kg i.v., Inj. Flunixin meglumine at 2.2mg/kg i.m., and Inj. Chlorpheniramine maleate at 0.5mg/kg i.m. for three days. The skin sutures were removed on 10th post operative day. The animal recovered uneventfully.

Effect of heat stress amelioration through open-ridge ventilated thatched roof housing on production and reproduction performance of crossbred Jersey cows

The present study was conducted to assess the impacts of loose house roofing designs and materials on modulation of micro-climate of the cow shed and its influences on production and reproduction performance of lactating crossbred Jersey cows. The control group (T0) was kept in a traditional single-slope asbestos roof shed and treatment group (T1) at a specially designed open-ridge ventilated, double-slope thatch roof shed. Lactation stage, average daily milk yield, and average parity at the beginning of the experiment were kept similar between T0 and T1 cows. The specifically designed T1 shed had significantly (P < 0.05) lower temperature, humidity, and thermal humidity index as compared to the traditional shed (T0). The T1 shed was cooler and more comfortable than T0. Housing significantly (P < 0.05) influenced cardinal physiological parameters of resident cows. Body temperature, pulse rate, respiration rate, and discomfort index were significantly (P < 0.05) higher in T0 as compared to those in T1 cows. Improved housing significantly (P < 0.01) influenced milk yield, composition, quality, and udder health of cows. Daily milk yield depending on parity, monthly milk yield, milk fat, SNF, and protein were significantly (P < 0.01) higher in T1 than those in T0 cows. The milk somatic cell count, modified California mastitis test score, electrical conductivity, and pH of milk samples of T0 cows were significantly (P < 0.0) higher than those of T1. Effect of housing type, parity, and interaction of housing × parity did not cause any significant (P > 0.05) differences in reproductive traits such as service period, break period, calving interval, pregnancy rate, and other cow fertility parameters. Post-partum body condition score and body weight loss did not differ significantly (P > 0.05) between the two groups; however, more loss occurred in T0 than T1. The estimated net profit from housing of cows (N = 20) in a comfortable shed was 2200kg milk per annum, i.e., 110kg/cow/annum. The study concluded that a central open-ridge ventilated, double-slope thatched roof design created a favorable micro-environment and it significantly affected cows' comfort index; thermo-comfortable housing significantly reduced the heat stress-oriented drop in milk yield and decline in milk composition, and improved udder health and other milk production traits; however, its impact was non-significant on reproduction and fertility traits in Jersey crossbred cows.

Besnoitia besnoiti natural infection in a crossbred cow in India

Besnoitia besnoiti is an obligate intracellular parasite that causesbesnoitiosis in cattle, goats, and equids.Acute besnoitiosis is characterized bypyrexia, enlargement of the lymph nodes, anorexia, ruminal atony, and necrosis of the epidermis. A crossbred Jersey cow was referred for respiratory distress, swollen lymph nodes, patchy dermis, pyrexia, and anorexia. Skin histopathology revealed Besnoitia cysts. The animal was treated with oxytetracycline (10 mg/kg body weight, IV) for a week and with ivermectin (200 μg/kg, SC) once a week for 75 days with supportive therapy. Chronic bovine besnoitiosis was diagnosed, and the author concluded that no therapeutic plan would be successful. This case is unusual because besnoitiosis is not commonly reported in India

Cavernous haemangioma of thymus : A rare vascular tumour in a cross bred cow

A six-year-old cross bred Jersey cow was presented for necropsy. On examination of thoracic cavity, pericardium over the base of the heart revealed dark reddish, firm, tortuous mass embedded in thoracic part of thymus surrounded by adipose tissue. Histopathological of the tissue revealed thymus with involution changes. Lobes were shrunken. Capsule was thin and was surrounded and infiltrated by adipocytes. Thymic lobules were shrunken, follicles were atrophied. Cortex and medulla were non-de- lineated containing condensed area composed of epithelial cells, Hassall’s corpuscles and thymocytes. Cystic degenerations were noticed in Hassel’s Corpuscles, epithelial cells and stromal tissue. Thymocytes were arranged to form acinar pattern. Atrophic thymus showed variable sized vascular channels filled with blood. The vascular channels were lined by endothelial cells. The stroma composed of fat and fibrous tissues admixed with remnant of thymic tissue and follicles. Based on the location, gross and histopathological features of the tissue, the case was diagnosed as cavernous haemangioma of thymus in a cross bred Jersey cow.

Clinical and Ultrasonographic examinations in cattle with empty rectum

Ultrasonography helps in early diagnosis of large animal digestive disorders especially in cattle with empty rectum and also to initiate early therapeutic and surgical management. The study was undertaken to elicit GI disturbances in cattle at TVCC, VCRI, Orathanadu during 2015-16. Animals with history of absence of feces and or empty rectum were selected for this study. In total twenty nine cattle were found to be affected with various GI disorders. The incidence of GI disturbances was more (65.52 %) in cross bred Jersey cow. The common clinical signs were absence of feces (65.52 %), anorexia (58.62 %), scant/tarry/mucous coated foul smelling feces (34.48 %), arched back (24.14 %) and abdominal distention (24.14 %). All selected 29 animals were subjected to abdominal ultrasonography which revealed peritonitis (31.03 %), paralytic ileus with peritonitis and pericarditis in each 10.34 %, uroabdomen, intussusceptions, caecal dilatation, abomasal dilatation and peritonitis with intussusceptions in each 6.90 % and diaphragmatic hernia, reticular abscess, omasal impaction and peritonitis with pericarditis in each 3.45 %. Based on this study, clinical and ultrasonographic examinations were found to be a useful tool for the diagnosis of GI disorders of cattle with empty rectum.
