The aim of the study was to assess changes in the vaginal bacteria load, at different times following treatment with intravaginal Progesterone implants. Thirty postpartum (>70 days) anestrus crossbred cows were treated with three standard hormonal protocols (CIDR Gr. II, TRIU-B Gr. III and P4 Sponge Gr. IV protocols, n=10 each), and the findings were compared with a group of untreated (n=10) anestrus cows which were inserted with blank sponge (containing no P4).

The present study was conducted to compare the efficacy of hormonal and nutritional approaches to induce fertile estrus in canine. Twenty female dogs of different breeds presented to university clinics, GADVASU, Ludhiana were subjected to hormonal (Group 1, n=10) and nutritional (Group 2; n=10) treatments. The breeds of these dogs were Labrador, Dalmatian and German Shephard weighing between 25-30 kg with the history of not showing estrus despite attaining age of puberty (≥ 1.5 years of age).

Haematological profiles play a key role in diagnosis of array of reproductive disorders. Postpartum lactating anestrous Ongole cows were treated with estrus and ovulation hormonal protocols Heatsynch (Group A) and G6G (Group B) and haematological analysis was done following estrus induction. The mean of haemoglobin level was 9.94±0.47, 10.51±0.27 and 10.23±0.68, 10.93±0.45 g/dl on day of selection (0 day), on day of induced estrus in Heatsynch and G6G groups, respectively. The mean PCV was 28.97±1.04, 33.92±1.31 and 30.24±1.74, 34.49±0.
