Plasma Nesfatin-1 and Leptin in pubertal and non-pubertal Murrah buffalo heifers (Bubalus bubalis)
AbstractBuffaloes mostly suffer from delayed puberty,
anestrus, subestrus, summer infertility, prolonged
inter-calving interval and postpartum uterine
disorders. Nesfatin-1 and Leptin are directly or
indirectly related with body weight (BW), feed
parameters and regulation of puberty. The objective
of this study was to investigate the influence of
Nesfatin-1 and Leptin in pubertal and non-pubertal
Murrah buffalo heifers. The Murrah buffalo heifers
(n=13) were randomly selected and divided into two
groups; pubertal group (PG) and non-pubertal group
(NG). Heifers with plasma progesterone (P 4 ) level of
?1 ng/mL were classified as PG. Blood samples were
collected at fortnight intervals for analysis of plasma
Nesfatin-1, Leptin, P 4 , glucose and non-esterified
fatty acids. Body weight, dry matter intake and feed
conversion efficiency were recorded at fortnight
intervals. The mean (±SEM) plasma Nesfatin-1,
Leptin, P 4 , BW and feed conversion efficiency (%)
were significantly (P<0.01) higher in PG as compared
to NG. Dry matter intake by the heifers was also
significantly (P<0.001) higher in PG than NG. Plasma
metabolites (glucose and NEFA) did not differ
significantly between the groups. The findings of this
study suggest that Nesfatin-1 and Leptin have
indispensable role in the onset of puberty in buffalo
heifers by affecting BW and feed parameters.
