Amrithmahal Project : Milk yield and its composition: The Amrithmahal cows were non cooperative to assess their milk yield by direct measurements. Hence, a new method of assessment of milk yield was developed at the station “ Indirect method by weightiest of calf before and after suckling”. Here in this method the calves were weighed before and after suckling milk from cows twice a day - once in morning and evening. The difference in weight of calves was added up to obtain the milk yield of the cows per day .This was further projected as milk yield per lactation ( kg/d). The composition of the milk was assets using milk - O - tester. The milk yield (kg/d) ranged 1.6 to 2.4 kg.
Adoptiveness of the Amrithmahal cattle for humans (Behavioral study). The study was conducted to assess the adoptiveness of the Amrithmahal cattle for the humans / working labour. Here in out off 25 cows, 19 cows gradually were adopted for the working staff for weighment, handling of cows and calves, during treatment and other routine procedures. Any way they were not cooperative for assessment of milk yield body weight measurement etc. They followed stereo typed methods of herd behavior, tying at mangers, grazing. Hematological analysis: The blood and serum of the all the animals were subjected for labourarory analysis for the following parameters: Hb, WBC, RBC, Platelets, Neutrophils, Lymphocytes, Eosinophils, Monocytes, SGPT, SGOT, BUN, Creatinine, Calcium, Phosphorus, Total Protein, Albumin, incidence of Johne’s disease by indirect ELISA, FMD by LBP ELISA.
The Haemoglobin (g%) values ranged from 9.1 to 12.3; WBC( X/103 μl) ranged from 3.9 to 19.1; RBC (X/106 μl) ranged from 5.34 to 10.53; Platelet count (X/105 μl) ranged from 64 to 419; Neutrophils (%) ranged from 20 to 78; Lymphocytes (%) ranged from 10 to 71; Eosinophils (%) values ranged from 03 to 20; Monocytes (%) values ranged from 01 to 03.
Results obtained by Serum analysis of the Amrithmahal cattle revealed that SGPT (U/L), a test to assess normal functioning of liver, ranged from 11.3 to 33.7; SGOT (U/L) ranged from 61.88 to 97.47; BUN (mg/dl) values have varied from 19.5 to 29.4; Creatinine (mg/dl) which is the indicator of kidney function test fell within range of 0.62 to 1.91.
Amrithmahal cattle were evaluated for Mineral status in terms of Calcium (mg/dl) ranging from 7.02 to 10.9; Posphorus (mg/dl) ranging from 5.40 to 9.17.
Nutritional status as observed by Serum analysis revealed that Total Protein (g/dl) ranging from 5.32 to 7.36; Albumin (g/dl) ranging from 2.22 to 3.69. Globulin by deductive calculation (Globulin=Total Protein-Albumin) ranged from 3.1 to 3.67 and the ratio of Albumin:Globulin ranged from 1.005 to 1.39.
The haemotological and biochemical values of all the animals fell in normal range showing that the Amrithmahal stock at LRIC(A) was healthy, nutritionally sound and disease free.
The body scores of the animals ranged from 6.5 to 7.4 in a scale from 0 to 8 body scoring system.
Morphometric measurements: The animals were measured for heart girth, body length, height at withers, tail length, ear length, parietal girth, face length, horn length and other relevant body measurements every month. These were compared with the direct measurements of body weight to find the correlation.
Morphometric measurements of cows (cm, minimum to maximum): Body length ranged from 96 to 119; height at withers ranged from 102 to 118; Chest girth varied from 115 to 143; Parietal girth observed within range of 118 to 136; face length 37 to 45; PL (forehead) 12 to 16; Horn length within range of 14 to 24; Ear length ranging from 15 to 19 and tail length ranging from 57 to 78.
Morphometric measurements of Bulls (cm, minimum to maximum): Body length ranged from 109 to 110; height at withers ranged from 115 to 122; Chest girth varied from 131 to 142; Parietal girth observed within range of 138 to 149; face length 42 to 43; PL (forehead) 15 to 15; Horn length within range of 16 to 17; Ear length ranging from 20 to 21 and tail length ranging from 63 to 74.The morphometric observations have shown growing prominence of the bulls over cows in terms of Chest girth, body length, height at withers, horn length with age and approachment of maturity.
The parameters about age at maturity, age at mating, age at first calving, inter calving period, drafting capacity of bulls w.r.t. weight of bullock cart, drafting capacity of bulls w.r.t. working in field, drafting capacity of bulls w.r.t. hours of work, lactation length, number of services/conception and other relevant parameters are planned for tabulation.
Period vaccination, deworming, treatment for ectoparasites were followed to keep the animals in healthy condition.
