(ST, CW, BD, WH, HG, BL and RW). It is therefore suggested that in selecting for body conformation these genetic and non genetic factors should be taken into consideration.

An experiment was conducted to evaluate the effect of vitamin C in chicken and quail egg yolk extender on sperm motility in chilled stored bull semen. Semen was collected from the bull with the aid of artificial vagina and six types of extenders were prepared using chicken and quail egg yolk with each extender divided into three aliquots having 0, 3 and 6 mg/mL Vitamin C levels. Bottles containing the diluted semen using the chicken and quail egg yolk °extenders were stored in a refrigerator at 5C over a period of three days and monitored or evaluated at 0, 24, 48 and 72 hours. The result showed that there was a general decline in motility of semen as storage time increases, although samples with 6mg/mL Vitamin C levels had better results. It can be concluded that adding Vitamin C in chicken and quail egg yolk 0extender maintained motility of chilled semen even at 72 hours of preservation at 5C.

The aim of this study was to determine the lactation curve traits of White Fulani (WF) and Sokoto Gudali (SG) lactating cows. Wood's gamma and Wilmink's curve parameters were employed to identify the lactation curve types and values for the parameters beginning yield (a) , coefficient of rising (b), coefficient of decreasing (c)t=timeande= is the exponential.The parameter assumed a fixed value derived from a preliminary analysis and disassociated with the time at peak yield were used to determine the shape and type of lactation curve. All Parameters in a typical lactation curves were positive, and in the event of one parameter being negative, the curve was considered to be an atypical lactation curve. Lactation records from WF (n=96)and SG (n=130) cows were recorded in the study area between year 2016-2017. Cows were hand-milked twice per day in the morning and evening from the 5 day post-partum till the end of the lactation period (260-270 days).Prediction equation of milk yield showed R values ranging from (32.00) in the SG to (35.00) in the WF. It was observed that the Wood's model curves were typical while Wilmink's model curves were atypical respectively. For typical lactation curves, a, b, c, persistency (S), time after parturition until the peak yield occurs (T ), maximum daily peak yield (Y ), and coefficient of determination (R ) were - 0.25±0.13, 1.08±0.07, 0.23±0.19, 2.34,51.00,2.62 and 97 for WF lactating cows and - 0.23 ± 0.14,1.13 ± 0.08, 0.07± 0.03, 2.33, 51.26, 2.58 and 96 for SG Lactating cows respectively. Parameters predicted by the Wood's model have the potential of being useful for breeding programmes in the SG and WF cows.

The objective of this study was to provide information on the morphological structure and body indices of Bunaji cattle and their crosses. Body weight and eight (8) morphological traits of 72 Bunaji and 60 Friesian x Bunaji cows were measured. The morphological parameters were used to calculate nine body indices. The analyzed morphological traits showed that the crossbred cows were heavier with larger morphological structure than the pure breed; however, both animals slightly slope forward although not very unbalanced. The correlation coefficients amongst the morphological traits in Bunaji were all positive and significant (P< 0.05 – 0.01) except for correlation of Rump Width (RW) with Body Depth (BD: r = 0.352) and Body Length (BL: r =0.210). However, the correlation coefficients amongst the morphological traits in the crosses were generally weak. The strongest correlation was observed between BW and HG (0.926) and between BW and RW (r = 0.946) in Bunaji and their crosses, respectively. The Principal Component Analysis (PCA) of the morphometric traits extracted one component with total variance of 67.67% in Bunaji and two components with total variance of 74.30% in the crosses. The first factor in each case had higher loadings for variables relating to body size, while the second PC in the crosses had high association with traits that reflect the body shape of the animal. The HG and RW were the single most informative morphological traits for estimation of BW in Bunaji and Friesian x Bunaji, respectively. In Conclusion, the Bunaji cattle are medium size animals, although they are used for both meat and milk production (multipurpose) there morphology showed some resemblance to milk type animal, thus suggesting a possible genetic improvement of these animals for dairy purpose.
