Opis:
Data on body weight and morphometric traits from one hundred and fifty-eight (158) live African cat fish sampled from two locations around Okitipupa within Ondo State, Nigeria was subjected to simple statistics analysis, Pearson’s correlation and analysis of variance to test for the effect of sex, age, location and body size on the body weight and the morphometric traits. The coefficient of variation (CV) varied among the parameters were considered. Results obtained revealed that body weight had the highest value (46.18%) in the adult fish while it was 22.76% in juvenile fish. Insignificant effect of sex (p > 0.05) was observed in both adult and juvenile fish in all the parameters considered. Age had a very highly significant effect (p < 0.0001) on all the parameters considered. The adult had higher values compared to the juvenile in body weight and the morphometric traits. Effect of body size was significant (P < 0.0001) on body weight and morphometric traits, the estimates increased from small size to medium to big size. Significant effect (P < 0.0001) of location was observed only on body weight, total length, standard length and head length. The fish from farm A had higher values compared to farm B. The correlation coefficients among the traits for juvenile and adult fish ranged between low to high and were significant (P < 0.05, P < 0.01 and P < 0.0001). Morphometric traits can be used in characterizing African catfish based on age and body size.

Opis:
This study was carried out to investigate litter traits performance of ASF-recovered pigs at Teaching and Research Farm of Federal University of Agriculture, Abeokuta. Data were collected on 52 progenies farrowed by eight (8) sows and two (2) boars, comprising of four (4) Large White sows, two (2) Large Black sows, two (2) Duroc sows, one (1) Large White boar and one (1) NigerHyb boar. These are survivals from ASF outbreak in 2005. Data were collected on the litter traits and subjected to General Linear Model (GLM) procedure using SAS, (1999) statistical package. Results obtained revealed that the litter traits estimates for the cross among the Large White were 6.52±0.26 (litter size at birth), 5.72±0.23 (litter size at weaning), 6.92±0.34 kg (litter weight at birth), 1.05±0.01 kg (average pig weight at birth), 7.08±0.35 (average pig weight at weaning), 12% (pre-weaning mortality) and sex ratio at birth (52%) and at weaning (54%). In the crosses between Duroc and NigerHyb, and Large Black and NigerHyb, effect of dam genotype was significant (P<0.01) on litter weight at birth and weaning, litter size at weaning and average pig weight at birth, higher values were observed in the cross between Large Black and NigerHyb, but not significant on litter size at birth and average pig weight at weaning. The litter traits estimates observed in this study are similar to those reported before the outbreak of ASF in 1997 in Nigeria.
