K. Durowaye A. E. Salako O. H. Osaiyuwu O. E. Fijabi <p>The objective of this study was to predict the live weight (LW) of domestically kept Grasscutters from some morphological parameters.&nbsp; The study was carried out at the Grasscutter section of FAK Farms, Apata, Ibadan. Data were recorded on body length (BL), tail length (TL), heart girth (HG), wither height and head length (HL) and body weights of 45 animals (25 females and 20 males) selected at random. Body weights and linear body measurements were recorded for the animals at 3, 6, 9 and 12 months of age using the simple kitchen digital weighing balance and traditional tape measure respectively and the data obtained were subjected to descriptive statistics, Pearson correlation and regression analysis (P=0.05). Mean body length, tail and head lengths, heart girth and wither height were 51.38±3.03cm, 16.76±1.05cm, 10.01±0.42cm, 28.90±1.39cm and 13.66±0.75cm respectively for the male Grasscutters and 45.92±10.01cm, 14.62±0.84cm, 9.40±0.42cm, 28.06±1.41cm and 13.83±0.78cm respectively for the female Grasscutters. The correlation coefficients between LW and body measurements ranged from 0.251 to 0.909 for the male grasscutters and 0.347 to 0.945 for the female grasscutters with the highest correlation of 0.909 and 0.945 for the association between liveweight (LWT) and HG for males at 12 months of age and females at 9 months indicating sexual dimorphism.</p> <p>The coefficients of determination (R<sup>2</sup>) for the prediction equations recorded highest for heart girth {LWT= -0.101+0.095HG (82.6%)} at 12 months and {LWT= -2.671+0.148HG (89.4%)} at 9 months for the male and female Grasscutters respectively. Using the linear function from the R<sup>2</sup> value, BL, WH and HG were better predictors of LW than TL and HL. The best predictor of body weight was heart girth for both the male and the female.</p> <p>In conclusion, the use of BL, WH and HG in a given function explained better the variation in LW than the use of just one body measurement and can provide a basis for selection.</p> 2021-07-02T00:00:00+00:00 ##submission.copyrightStatement## Assessment of Dairy Cows for Milk Yield in the Cool Tropical Climate of Plateau State, Nigeria 2021-07-03T13:50:19+00:00 D. O. Omoniwa R. O. Okeke O. O. Adeniyi J. M. Madu D. S. Bunjah Umar <p>Genetic improvements of milk yield in the tropics necessitate the use of exotic cattle to the upgrade the performance of local cattle<strong>. </strong>The data for the study came from two different genotypes namely Holstein Friesian and FriesianxBunaji crossbred on the Plateau State in Nigeria. Milk production traits measured were 305-day fat corrected milk yield, daily milk yield, 100-day fat corrected milk yield, total fat yield, total protein yield and lactation length. Six milk production indices (Fat corrected milk yield kilogram weight; FCM Kg W, fat corrected milk yield kilogram metabolic weight; FCM Kg MW, fat corrected milk yield per day per kilogram weight; FCM/day/kgW, fat corrected milk yield per day per kilogram metabolic weight; FCM/day/kgMW, net energy efficiency and dairy merit). The R 3.0.3 statistical software was used for basic descriptive, t-test and regression analysis. Milk production traits were significantly (P&lt;0.05) influenced by genotype. Neural network models had the best prediction accuracy for estimating milk yield. It is concluded that considerable genetic variation existed between genotypes in milk production and efficiency traits.</p> 2021-07-03T00:00:00+00:00 ##submission.copyrightStatement## Prevalence and Pathology of Caprine Coccidiosis in South Darfur State, Sudan 2021-07-20T12:32:41+00:00 Mohammed Ahmed Abdalla Khairelsiad Amir Mustafa Saad Yassin Abdulrahim A. Abdelnasir El Tigani Ahamed El Tigani Mohammed Hamid <p>This study was carried out to investigate the prevalence and pathology of coccidiosis in local breeds of goats in South Darfur State and the factors affecting it. One hundred faecal samples were directly collected from the rectum during September – December 2017, from goats, kept in an open system. The animals were grouped according to sex (34 males and 66 females), and according to age group (85 goats in the age one year or more, 15 less than one year). Oocysts were detected using the floatation method; the McMaster method was used for oocysts count. Length, width and size were measured by calibrated microscope attached to computer for the parasite identification. On the other hand, 100 samples of intestine sections were collected for gross and microscopic examination, from Nyala North slaughterhouse. The gross intestinal lesions were reported and sections for histopathology were made according to standard method. The overall prevalence of coccidiosis in goats was 65% in South Darfur State. Eimeria species identified were: <em>E. alijevi</em> (15.7%), <em>E. hirci</em> (26.3%), <em>E. ninakohlyakimovae</em> (36.8%), and <em>E. caprovina</em> (21%). The infection was higher in goat kids compared to adults. The gross lesions were characterized by scattered white nodules in the intestinal wall particularly in the jejunum and ileum as well as hemorrhages. Microscopically there were hemorrhages in the mucosa; hyperplasia of the mucosal epithelium with infiltration of inflammatory cells mainly lymphocytes, plasma cells, and eosinophils in the lamina propria, and presence of different developmental stages of the parasite in the intestinal epithelium and mucosal glands. Coccidiosis in goats resulting from complex interactions between parasites and host with many factors contributing to the severity of the disease, kids are more susceptible to infection with the clinical coccidiosis.</p> 2021-07-20T00:00:00+00:00 ##submission.copyrightStatement## Haematological Indices of Growing Rabbits Fed Herbaceous Plants as Sole Diet 2021-07-30T05:37:46+00:00 S. S. Aderibigbe D. O. Adejumo O. E. Fijabi T. G. Johnson <p>Competition between humans and animals for food is inevitable since some feed stuffs used as animal feed are also consumed by humans. Therefore, suitable alternatives for animal feed are compelling. This study was conducted with 32 mixed bred (New Zealand white and Chinchilla) growing rabbits (16 bucks and 16 does of 7 to 8 weeks old and of average weight 1.03kg) for a period of seven (7) weeks to assess haematological indices of rabbits fed herbaceous plants as sole diet. The rabbits were completely randomized into <em>Corchorus olitorius </em>(T1)<em>, Moringa oleifera </em>(T2) and<em> Telfairia occidentalis </em>(T3) and commercial feed as the control diet (T0), with each treatment having eight rabbits, in four replicates of two rabbits per replicate. Blood samples were collected pre and post exposure to the treatment. Haematological parameters assayed were packed cell volume (PCV), red blood cell (RBC), white blood cell (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). Analysis of Variance (ANOVA) was carried out for the assessment of the variations in these parameters. The values obtained (Mean ± SD) for each blood parameter pre-exposure to the treatment were within the normal physiological range of healthy rabbit, except the value of the Mean corpuscular volume (MCV) which was lower than the normal physiological range. Blood indices assayed for, post exposure to treatment showed significant difference (P &lt; 0.05) in the Mean corpuscular hemoglobin. Based on the data from the haematological parameters. It was concluded that Corchorus olitorius could solely sustain rabbits with no adverse effect on their well being.</p> 2021-07-30T00:00:00+00:00 ##submission.copyrightStatement##
