    STUDIES ON METABOLIC AND HEMATOLOGICAL PROFILES IN CROSSBRED COWS WITH CYTOLOGICAL ENDOMETRITIS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021) AVINASH R.G.; A M KOTRESH
    The cytological endometritis (CE) is an inflammation of the endometrium without visible clinical signs significantly impairing the fertility in dairy cows. The study was undertaken to assess the metabolic stress and hematological profile influencing CE in crossbred dairy cows reared in the central dry zone of Karnataka. Apparently healthy crossbred cows in 3-11th week postpartum (WPP) were divided into four groups (each N=8) viz., Group- I as control having crossbred cows at 3-11th WPP estrus, Group- II at 3-5th, Group- III at 6-8th and Group- IV at 8-11 WPP estrus. CE was diagnosed based on cytobrush technique. A significant(p<0.05) increase in concentrations of BHBA and NEFA found in all CE groups compared to control group. There was no significant difference (p<0.05) found in blood glucose, serum total proteins, creatinine, AST, ALT levels in all CE cow groups compared to control group. The BUN, total cholesterol and bilirubin levels were found significantly(p<0.05) higher and calcium and phosphorous values were lower in CE affected cow groups compared to control group. There was no significant (p<0.05) difference in blood parameters such as WBCs, lymphocytes, HB, PCV, MCV, MCH, MCHC, platelet among all CE groups when compared to control group. There was significant (p<0.05) increase in percentage of neutrophils and reduced RBC levels were found in CE affected cows. There was a positive correlation found with respect to NEFA and BHBA with lymphocytes, neutrophils activity in all CE affected cow groups. There was negative correlation found between calcium and phosphorous with lymphocytes, neutrophils activity in all CE cow groups. Key words: Cytological endometritis, Metabolic stress, Hematological profile, Body condition score.

    EVALUATION OF DIETARY BETAINE SUPPLEMENTATION ON HEMATO-BIOCHEMICAL PROFILE, MILK YIELD AND MILK COMPOSITION IN DEONI COWS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-03) SONABAI KONDIBA; SHRIKANT KULKARNI
    A study was conducted to assess effects of dietary betaine supplementation on haemato-biochemical profile, milk yield and composition, SCC, biochemical characteristics in lactating Deoni cows. Twelve lactating cows were randomly divided into control and treatment group with six in each group. Control group was fed basal diet alone whereas treatment group was supplemented with anhydrous betaine hydrochloride @ 15 g/ day in the diet during the study period of 8 week in addition to basal diet. The average daily milk yield improved significantly (P<0.05) in treatment group from 5th week; milk fat and solids not fat from 3rd week of after supplementing betaine. There was no significant difference in milk lactose level between two groups during the study period. Somatic cell count in the milk declined significantly (P<0.05) in betaine supplemented Deoni cows from 4th week of study. There was no difference between two groups in TEC, Hb, PCV and TLC. Percentages of lymphocytes were significantly higher and that of neutrophils were lower in treatment group as compared to control. The concentration of cholesterol, triglycerides and BUN were significantly (P<0.05)decreased from 4th week and total proteins increased from 2nd week of betaine supplementation in lactating Deoni cows. There were no significant differences in plasma electrolytes in betaine supplemented groups compared to control, although plasma sodium and potassium were numerically higher and chloride levels were numerically lower when compared to control group. It can be concluded that dietary betaine supplementation to lactating Deoni cows enhances milk yield and improves milk composition and udder health.
