Abstract
Post-partum anestrus and repeat breeding condition continue to be the most common and puzzling infertility problems in daily animals. Certain blood constituents during different reproductive periods have been found to be associated with the fertility status of animals and their reproductive behaviour. Variations in certain blood constituents in blood during different reproductive periods affect or upset proper functioning of the reproductive organs. HaematĀ©logical and biochemical constituents of blood have great diagnostic value in the clinical practice. Keeping these in view, an attempt was made to evaluate the difference, if any, in the haematological, biochemical and milk urea levels in normal cycling, repeat breeding and anestrus dairy animals. Haematological (Hb, PCV, TSC and TLC) and biochemical (serum calcium, inorganic phosphorus, magnesium, total protein, blood glucose, blood urea nitrogen and milk urea nitrogen) estimations were carried out in 82 post-partum Surati buffaloes and 35 crossbred (K x J) cows during the period from June to September 1989. These animals were divided into normal farm animals, normal cycling field animals, repeat breeding field animals and anestras field animals. Ten Surati buffaloes from Reproductive Biology Research Unit, Griijarat Agricaltaral University, Anand and ten'crossbred (K x J ) cows from Livestock Research Station, GAU, Anand were taken as normal cycling farm animals. Ten Sarati buffaloes and ten crossbred (Z x J ) cows from the animals presented at the A.I, Centre, Veterinary College, GAU, Anand for artificial insemination (A.I) and sexual health check-up were selected as normal cycling field animals. Animals presented for the sexual health check-up were screened and on the basis of individual case history of calving, reproductive cycle, number of insemination or service, repeat cycle and gynaecological examinations, 20 buffaloes as repeat breeders, 42 buffaloes as anestrus condition and 15 crossbred cows as repeat breeders were selected for the study. Haematological study revealed that haematological parameters did not show significant changes between farm and field normal cycling buffaloes and cows. Haemoglobin values of repeat breeder and anestrus buffaloes were significantly (P/.0.01) low as compared to farm normal cycling buffaloes. Packed cell volume (PCV), total erythrocytic count (TEC) and total leucocytic count (TLC) values did not reveal significant changes in repeat breeder and anestrus buffaloes as compared to farm normal cycling buffaloes. Haemoglobin and packed cell volume (PCV) values of repeat breeder cows were significantly (P /0.01) low as compared to field normal cycling cows. Total erythrocytic count and total leacocytic count (TLC) values did not reveal significant changes in repeat breeder cows as compared to field normal cycling cows. Biochemical parameters except serum inorganic phosphorus, total protein and blood glucose in buffaloes, did not show significant changes between farm and field normal cycling buffaloes and cows. Serum inorganic phosphorus, magnesium, total protein, blood glucose, blood urea nitrogen values were significantly (P /0.01) low in repeat breeder and anestrus buffaloes as compared to farm normal cycling buffaloes. Serum calcium and milk urea nitrogen values did not revealed significant changes in repeat breeder and anestrus buffaloes as compared to farm normal buffaloes. Serum inorganic phosphorus and magnesium values were significantly (P /0.01 and P/0.05) low in repeat breeder cows as compared to farm normal cycling cows. Milk urea nitrogen values was significantly (P /0.05) high in repeat breeder cows as compared to farm normal cycling cows. Serum calcium, total protein, blood glucose and blood urea nitrogen values did not revealed significant changes in.repeat breeder cows as compared to farm normal cycling cows.
