“…The kids of Red Sokoto goats apparently employed more efficient adaptive and survival strategies than Sahel goat kids, particularly during the HDS, which prevented the dramatic change in haematological parameters that was observed in Sahel goats. The higher magnitude of the increase in PCV and RBC in Sahel compared with Red Sokoto kids during the HDS may imply higher thermoregulatory fluid loss in Sahel kids, probably due to higher respiratory rate (Habibu et al, 2016b). This difference in breed response may be due to variation in thermoregulatory plasma fluid dynamics, as higher plasma volume, indicated by decrease in RBC and Hb has been reported in adult bucks of Red Sokoto, while an increase in PCV and RBC was observed in Sahel goats during the HDS when compared with CDS and RAS (Habibu et al, 2017).…”

“…However, both the canonical plot representation and the group membership prediction showed that the CDS imposed distinct effects on haematological variables from those by the HDS and RAS which were similar. This was probably due to the low THI during the CDS and high THI during the HDS and RAS, which may induce cold stress and heat stress, respectively (Habibu et al, 2016b).…”

Abstract. The influences of breed, sex and age on seasonal changes in haematological variables of kids (1-4 months old) belonging to Red Sokoto (n = 60) and Sahel (n = 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 (P < 0.05) packed cell volume (PCV) and red blood cell (RBC) count but lower (P < 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 (P < 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 (P < 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.

A study was conducted to assess comparatively the growth performance of three different indigenous goat breeds during exposure to summer heat stress. The primary objective of the study was to observe the heat stress impact on the growth performance based on the body weight changes, allometric measurements, growth hormone (GH) concentration and peripheral blood mononuclear cell (PBMC) Insulin-like growth factor-1 (IGF-1) mRNA expression pattern during the summer season in comparison with the local breed (Osmanabadi). Thirty-six ten-month- to one-year-old female goats of Osmanabadi, Malabari and Salem Black breeds were randomly divided into six groups, OC (n = 6; Osmanabadi control), OHS (n = 6; Osmanabadi heat stress), MC (n = 6; Malabari control), MHS (n = 6; Malabari heat stress), SBC (n = 6; Salem Black control) and SBHS (n = 6; Salem Black heat stress). Body weight was recorded at weekly intervals, whereas other growth and allometric measurements and blood collection were carried out at fortnightly intervals. Breed factor significantly (p < .05) influenced only few growth variables such as body weight, body mass index (BMI) and body condition score (BCS). However, heat stress treatment significantly (p < .05) reduced all growth parameters expect BMI. Further, the heat stress significantly (p < .01) increased plasma GH concentration in goats with significantly higher (p < .05) concentration recorded in OHS. Among the stress groups, the lower (p < .05) PBMC IGF-1 mRNA expression was recorded in OHS, while the higher (p < .05) expression was observed in SBHS indicating the extreme adaptive capability of Salem Black breed. Thus, the results indicated that the Salem Black breed performed much better compared to both Osmanabadi and Malabari breeds indicating the superior ability of this breed to adapt to heat stress challenges. The results also indicated that plasma GH and IGF-1 gene may act as ideal biomarkers for assessing the heat stress impact on growth performance in indigenous goats.

o 12' N, longitude 7 o 33' E, and altitude of 610m above sea level. The health status of the goats was evaluated based on behaviour, rectal temperature, appetite and faecal consistency. Only clinically healthy animals were used for the AbstractThis study aimed at evaluating the effect of sex, age, breed and reproductive status on platelet count and total protein, and also to demonstrate the relationship between the two variables in goats during the cold-dry season. At the peak of the cold-dry season, 56 male and female goats belonging to Red Sokoto (n=28) and Sahel (n=28) as well as 14 Red Sokoto goats in the last trimester of gestation (n=7) and early lactation (n=7) were sampled and results statistically analysed. The results revealed that the platelet count was significantly (P<0.05) higher in kids, bucks, Red Sokoto and pregnant goats, while blood total protein was significantly lower (P<0.05) in kids, bucks, Red Sokoto and pregnant goats. In addition to this inverse relationship, a significantly negative correlation (P<0.005; r=-0.330) was observed between platelet and blood total protein.It was concluded that sex, age, breed and reproductive status markedly influenced platelet count and blood total protein in an inverse manner with a negative correlation between the two variables in goats exposed to a season with low ambient temperature. More studies are needed to directly establish and understand the relationship between platelet count and blood total protein on exposure to low ambient temperature so as to explore its effect on animal health, particularly during the peri-partum period and its benefit in individuals with haemostatic challenges.
