ABSTRACT: The haematological and biochemical parameters of 140 apparently healthy goats consisting of 70 adults (35 male and 35 female; 37 buck kids and 33 doe kids) comprised of 3 indigenous and popular breeds of goats of Nothern Nigeria were studied. Data were analysed for the effect of breed, sex and season. Packed cell volume (PCV) was significantly higher (P<0.05) for Kano brown (buck and doe kid) of the north west. Haemoglobin (Hb) values was also higher (P<0.05) for Kano brown adult buck and doe (P<0.05). Red blood cell count (RBC) was significantly higher (P<0.05) for Borno white adult buck and buck kid. The mean corpuscular haemoglobin (MCH) was higher in Kano brown doe (27.3) while the values were much higher in Sokoto red goat kids. The mean corpuscular haemoglobin concentration (MCHC) was significantly higher (P<0.05) for goat kids than in adult goats. The mean corpuscular volume (MCV) was observed to higher for Kano brown buck and buck kid than other breeds of goats. Borno white doe and doe-kid had the highest white blood cell count (WBC). White blood cell differentials shows that lymphocytes was significantly higher (P<0.05) for Borno white goats (adult and kids). Monocytes was only observed in Borno white goats. The serum sodium range from (136.0 to 156.0 mmol/l) for adult goats of all breeds, (132.0 to 160.0 mmol/l) for goat kids of all breeds. Serum potassium range from (6.5 to 9.4 mmol/l) for adult goats, (4.8 to 12.3 mmol/l) for goat kids. The chloride, HCO-3 and urea values was higher for adult goats than in kids for all the breeds. Values for creatinine, cholesterol and glucose was observed to be higher for kids than in adult goats. The values for total protein, albumin and globulin showed significant difference (P<0.05) among breeds age and sex. Moreso significant difference (P<0.05) was observed for the enzymes studied in all the breeds of goats of different sexes and ages.

ABSTRACT: Organic matter degradation of Acacia nilotica, Acacia sieberiana, Annana senegalensis, Balanites aegyptiaca, Cassia sieberiana, Combretum leati, Faidhebia albida, Maerua angolensis, Prosopis africana and Vitex doniana using two different techniques: (i) the in sacco nylon bag degradation and in vitro gas production techniques. Samples were incubated in sacco and in vitro for 24, 48, 72 and 96 h. In sacco and in vitro OM degradation kinetics were described using the equation Y=a+b(1-e-ct). The dry matter (DM) and crude protein (CP) were relatively high ranging from 934.00 to 984.60 g Kg-1 DM and 122.50 to 174.80 g Kg-1 DM in Cassia sieberiana and Acacis nilotica had the highest value (216.60 and 910.30 g Kg-1 DM for as and organic matter (OM) The highest value for neutral detergent fibre (NDF) and acid detergent fibre (ADF) was observed in Vitex doniana. The acid detergent fibre was generally high ranging from 86.40 to 144.70 g Kg-1 DM. The OM disappearance increases with increasing incubation time in all the browse forages ranging from 28.56 in Balanites aegyptiaca at 24 h to 76.53 in Combretum leati at 96 h. The OM degradation constant (a, b, a+b, lag T and ED) were all significantly different (P<0.05) except 'c' values. The cumulative gas production was generally low for all the browse forages Acacia sieberiana and Cassia sieberiana having the lowest (9.66 ml/200 mg DM) and Vitex doniana having the highest value (22.66 ml/200 mg DM) at 96 h incubation. In vitro gas production constant showed significant difference (P<0.05) except for rate of constant 'c'. It was concluded that in sacco OM disappearance parameters of browse forages such as the samples used in this study may be predicted from in vitro gas production parameters.
