    BIOLOGICAL EVALUATION OF EARTHWORM MEAL AS A REPLACEMENT OF FISHMEAL IN COMMERCIAL BROILER DIETS
    (CSKHPKV, Palampur, 2011-08-06) SHARMA, ROHIT; Sharma, K.S.
    ABSTRACT In the present scenario, poultry farming is becoming expensive day by day, mainly because of the increasing cost of the feed which alone accounts for about 70 percent of the expenditure incurred on poultry rearing. The present investigation was undertaken with the objective of exploring feasibility of replacing fishmeal with the earthworm meal in the diets of commercial broilers along with calculation of the cost benefit ratio of the broiler production. To achieve this, 500 day-old broiler chicks were divided into 5 groups and in each group fishmeal were replaced with the earthworm meal at 0, 25, 50, 75 and 100 percent levels. Growth characteristics, some parameters of blood plasma viz. calcium, phosphorus and cholesterol, chemical composition of meat, dry matter and nutrient digestibility and liveability percentage were studied. Broilers assigned to groups getting 100 percent earthworm meal as a replacement of fishmeal performed significantly better in terms of gain in live weight (13.36 percent compared to control) and FCR (2.17). Dressing percentage (66.03 %) was also found to be significantly better in the treatment group containing 100 percent earthworm meal. Further, the cost of feed and the total expenditure/kg gain in live weight) got reduced progressively as the level of earthworm meal was increased successively at different levels in the diets of the birds. As a result more profit/kg gain in live weight (12.10 % as compared to control in treatment group containing 100 percent earthworm meal ) was earned at each stage of substitution of fishmeal with the earthworm meal.

    STUDY ON EFFICACY OF DIFFERENT THERAPEUTIC REGIMENS ON RESTORING FERTILITY OF INFERTILE ABANDONED COWS MAINTAINED IN GOSHALAS OF HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2015-08-07) SHARMA, ROHIT; Singh, Madhumeet
    ABSTRACT Abandoned cows, reared in 18 Goshalas in different districts of Himachal Pradesh were examined clino-gynaecologically for reproductive status. Overall 321 abandoned cows diagnosed to be affected with 402 reproductive ailments (few of them with multifactor etiology) were taken for this study. These animals were treated as per the condition diagnosed. Uterine discharge samples of cows diagnosed as endometritis were subjected to culture sensitivity tests in Nutrient broth and Mueller Hinton agar. Blood samples were collected for estimation of minerals (Ca, P, Mg, Cu, Zn, Co, Mn. Na, K and Cl), biochemicals (Total Proteins, Cholesterol, ALT, AST, ALP and GGT), and hormones (T3, T4, TSH, cortisol, progesterone, estradiol-17β and insulin). There was highest prevalence of endometritis (27.8%) followed by cervical disorders (14.43%) which included cervical fibrosis, cervicitis, non-patent cervix and kinked cervix etc. However management errors were detected in 38.80 per cent animals. The antibiogram of uterine discharges indicated highest sensitivity for fluoroquinolones derivatives and gentamicin followed by tetracycline. Whereas high resistance was recorded forMetronidazole, Penicillin,Cloxacillin andNitrofurantoin. All bacteria were resistant toCotrimoxazole. Copper concentration significantly increased in recovered abandoned cows suffering from endometritis and treated anestrus cows, irrespective of recovery. Inorganic phosphorus concentrations significantly increased only in recovered true anestrus animals. The post-treatment recovery could be followed in 220 cows with 280 reproductive problems. A good proportion of endometritic cows (21.69%) responded to treatment whereas only 2.17 percent of the animals affected with cervical problems conceived. High post treatment recovery was recorded in true anestrus (42.17%) and silent estrus (56.25%) cows. In all 37 (16.82%) abandoned cows conceived out of total 220 cows followed to evaluate post-treatment recovery. Principal contributor to reproductive problems in abandoned cows was technical errors committed by personals handling genitalia (50.00%) of which only 12.75 per cent were treatable. Whereas, much higher (44.45 %) post treatment recovery rate was recorded in cows (38.80 %) suspected to have managemental problems.
