Lactation milk yield in dairy bovines is closely related with peak yield, persistency and lactation length. Therefore, characteristics, curve and persistency of lactation were studied in Gir cows. A total of 2,24,748 morning and evening milk production records of 300 lactations of 1-6 parity Gir cows present at Cattle Breeding Farm, JAU, Junagadh, Gujarat over a period of 31 years (1986-2016) were used for this study. Overall lactation length (LL), total lactation milk yield (TLMY) and standard lactation milk yield (SLMY) of the Gir cows averaged 371.59 ± 5.42 days, 2674.21 ± 48.79 lit and 2380.79 ± 37.68 lit, respectively. Overall daily peak yield (DPY) was 13.25 ± 0.17 lit/day, attained at 48.47 ± 2.40 days postpartum. Overall weekly peak yield (WPY) and weeks to attain WPY averaged 82.08 ± 1.11 lit/week and 6.54 ± 0.31 weeks, respectively. Weekly milk yield could be predicted using linear function [(y ̂ =79.5139+(-1.1002 × X)] and logarithmic function [(y ̂ =1.9378 × (-0.00965) ^X)] with an accuracy of 86 to 95%, while monthly milk yield could be predicted using linear function [(y ̂ =348.52+(-20.26 × X)] and logarithmic function [(y ̂ =2.588 × (-0.042) ^X)] with comparatively higher R2 value of 94.01 to 98.05%. Overall persistency, in terms of weekly and monthly milk yield was estimated to be 96.82 ± 0.13% and 88.77 ± 0.37%, respectively.

In the present study, 86 avian pathogenic E. coli isolates from chicken were subjected to multiplex PCR to detect the presence of virulence genes stx1, stx2, eaeA, and hlyA. Forty-seven isolates harbored one or more virulence genes, stx1, stx2, and eaeA while gene hlyA was not detected in any of the samples. Of these, 15 (17.44%) isolates harbored stx1gene, 11 (12.79%) isolates carried stx2 gene, 18 (20.93%) isolates were positive for both stx1 and stx2 genes and 3 (3.49%) isolates carried eaeA gene.
