Influences of breed, sex and age on seasonal changes in haematological variables of tropical goat kids
The influences of breed, sex and age on seasonal changes in haematological variables of kids (1–4 months old) belonging to Red Sokoto (<i>n</i> = 60) and Sahel (<i>n</i> = 60) goats were studied at the peaks of the cold-dry, hot-dry and rainy seasons in a West A...

| description | The influences of breed, sex and age on seasonal changes in haematological
variables of kids (1–4 months old) belonging to Red Sokoto (<i>n</i> = 60) and Sahel (<i>n</i> = 60) goats were studied at the peaks of the cold-dry, hot-dry and rainy seasons in a West Africa Guinea savanna climate. The results showed that, during the hot-dry season, Sahel goat kids had significantly higher
(<i>P</i> < 0.05) packed cell volume (PCV) and red blood cell (RBC) count but
lower (<i>P</i> < 0.05) mean corpuscular volume (MCV), mean corpuscular
haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) and
total leucocyte count than Red Sokoto kids. Similarly, younger kids of both
breed had significantly higher (<i>P</i> < 0.05) PCV and RBC but lower
MCV, MCH and MCHC compared with the older kids during the hot-dry season.
Younger kids (1–2 months) of both breeds exhibited significantly
(<i>P</i> < 0.05) high PCV and RBC but low MCH and MCHC during the hot-dry
season as compared with the cold-dry and rainy seasons, with the magnitude
of the change being greater in Sahel kids. More remarkable seasonal
fluctuations in haematological parameters were observed in buck kids than
doe kids of both breeds. Multivariate analysis revealed a clear distinction
between the change in haematological parameters during the cold-dry as
compared with the hot-dry and rainy seasons, with MCV having the strongest
discriminating power (0.91*). In conclusion, breed, age and sex variations
in haematological variables of goats were more pronounced in the hot-dry
season, during which the seasonal changes were more dramatic in kids of
Sahel goats, as well as in younger and male kids of both breeds. These findings may be useful in the management of tropical goat kids in different seasons. |
