“…Body weight is a function of frame or size and condition of animal (Philip, 1970). The average live weight of 1.3kg reported in this study is comparable to those reported by Egbunike and Oluyemi (1979), Mancha (2004), Fayaye et al (2006), Ezekwe et al (2000) and Sudik (2007) . Mopate and Lony (1999) reported similar average values in the local scavenging chickens of N'djamena, Chad.…”

This study was conducted in Song and Shelleng local government areas of Adamawa State, between January 2004 and December 2006, to determine some characteristics of local chickens. A total of 451 chickens of both sexes were examined. About 49% of the birds observed were males while 51% were females. The comb type was mostly single (96.45%). Eye colours were either dark brown (37.92%), light brown (28.82%), dark red (28.60%), light green (2.00%), pink (1.33%) or dark ash (1.33%). For plumage colour, 17.07% of the chickens were classified as black and mottled, 14.41% as dark red/golden, 13.97% as dark brown, 12.64% as brown and mottled while 9.76, 6.85, 6.86 and 6.21 were classified as ash, white, white and mottled, and black, respectively. Most chickens (38.8%) had pink shanks, while 23.28%, 16.63% and 12.42% had dark ash, ash ,and light yellow shanks, respectively. The remaining birds (8.87%) had either milky, red, light pink or ash and yellow shanks. Average live weight, body girth, body length and shank length were 1.3 kg, 27.59 cm, 18.23 cm and 8.72 cm ,respectively. About 40.47% of the eggs observed were light brown. The average clutch size, egg weight, egg length, egg width, shell weight and shell thickness were 7.86, 39.03g, 4.52cm, 3.16cm, 3.80g and 0.53mm respectively. Generally, the local chickens in the study area were mostly black and mottled with dark brown eyes and pink shanks, and mostly lay light brown eggs. There were also distinctive differences in almost all the measurable parameters. These distinctions provide the basis for which they could be classified into breeds.

“…Underfeeding diminished the ability of the gonads to respond to gonadotropin stimulation (Davies, Mann & Rowson, 1957). Moderate underfeeding or reduction of feed intake by 30% to 50% adversely affects semen production and quality (Ezekwe et al, 2003).…”

The study investigated the effect of dietary protein (groundnut cake and coconut cake) on the live weight gain, spermiograms, gonadalsperm reserves and fertility of boars. The study was conducted at the Swine unit of the Teaching and Research Farm, University of Uyo, Uyo, Akwa Ibom State. The university of Uyo was used in this study. It is located in the heart of Uyo, the capital of Akwa Ibom state, Nigeria. A total of 18 grower pigs of large white consisting of 15 boars and 3 sows were used for the study. The boars were randomly selected into 3 groups (Ti, T2 and T3)5 of five based on average initial weights (20-25kg) and were tagged appropriately while the sows were randomly placed in 3 group(S1, S2 and S3) of 1 in each group. Three diets were made for the three treatment conditions. The boars in T1which is the control group were given normal maize fed, boars in T2 which is the first treatment condition were given groundnut cake diet while boars in T3 which is the second treatment condition were given coconut cake. These pigs were fed twice daily and water supplied adlibitium. Finally, the sow in S1 was artificially inseminated with the semen of the Boar in condtion group 1 (T1), S2 was artificially inseminated with the semen of treatment condition 2 (T2) while S3 was artificially inseminated with the semen of treatment condition 3 (T3). During the feeding trial, weekly feed consumption and weight changes were recorded, while weight gain, feed conversion. Result showed a significant difference on the live weight gain of boars between groups (P < 0.05). Also, there was a significant difference on the spermiogenes and gonadal sperm reserves of boars between groups (P < 0.05). Finally, there was no significant difference on the fertility of sows between the treatment conditions (P> 0.05). It was concluded that dietary protein of groundnut cake and coconut cake could completely replace maize as they improve the live weight gain and sperms quality of boars. Implications and recommendations were made from the findings of the study.
