The effect of inclusion of graded levels of poultry offal in the diet of Clarias gariepinus on growth performance and cost effectiveness was determined. Group A (control) was fed with 100% concentrate ration while test group B was fed with concentrate at graded level of inclusion of poultry offal.

There was no significant difference (p<0.05) in the performance of the two groups in terms of growth rate (GR), specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency ratio (FER) and cost effectiveness (CE). Group A however had a higher final mean live weight and total length of 720gms and 47 cm relative to Group B with 465gms and 37cm respectively.

Assessment within group B using FCR, FER, GR, SGR and CE as indices shows that the performance varies within the group. Our study shows that poultry offal is a viable alternative to the more expensive conventional animal protein in fish feeds. An investigation into means of presenting it in an aesthetically acceptable way is hereby recommended.

In a 4-week trial, seventy-two Anak broiler day old chicks were randomly distributed to four experimental diets. Each diet had eighteen birds with three replicates. Each replicate had six birds. The diets were formulated by partial replacement of groundnut cake (GNC) with cassava leaf meal (CLM). Diet I was the control and contained 150g kg-1 of GNC. Diets 2, 3 and 4 were formulated with a 16.67%, 33.33% and 50% replacement of the GNC with CLM respectively

Inclusion of CLM up to a level of 5% in the diet caused a significant (P<0.05) increase in feed intake and body weight gain. Further increase in the level of CLM caused a depression in weight and feed intake.

Blood haematological parameters were not significantly affected (P>0.05) by CLM supplementation. CLM supplementation resulted in lower feed cost and weekly feed cost per unit weight of the birds. Results show that CLM can be used to supplement 33.33% of GNC in chick diets with positive results.

African giant snails, Archachatina marginata and Achatina sp. were examined cytologically with the aim of determining their chromosome numbers. The chromosome numbers were 2n=56 and 2n=44 for A. marginata and Achatina sp. respectively. Using the metaphase spreads of meiosis 1 in the ovotestes tissues of the snails, 28 and 22 bivalents were observed for A. marginata and Achatina sp. respectively. The chromosomes were large and rod like. Prometaphase and mitotic metaphase stages were also recorded for A. marginata while only mitotic metaphase stages were recorded for Achatina sp. The chromosomes at these stages were reduced in size. This could probably be an intrinsic feature of these species. No polyploidy was observed in all the cells examined.

Abstract

Morphometric studies were undertaken of the brain of Red Sokoto goat. A total of 13 frozen/unfixed specimens were used. The mean brain weight was 85.85±10.85g, mean brain length (from cerebrum, rostral to the coronal sulcus to the medulla oblongata at the level of the occipital condyles) was 10.19±0.52cm and the mean brain depth/ height was 4.67±0.34cm (measured from the level of the hypothalamus to the top of the cerebrum). The mean cerebellum depth, length and cerebrum length was 3.72±0.44cm, 2.83±0.39cm and 6.42±0.28cm respectively. The average ratio of brain to body weight was 0.006 or 1:165. There were no significant differences in brain linear dimensions, brain weight and brain to body weight ratio between male and female. There was, however, a significant difference P<0.05) between the brain weight and length, cerebellum depth, length and cerebrum length of animals between 15kg and those above this weight mark.

* Author for correspondenceAbstract

Separate questionnaires were designed for pet owners (clients) and veterinarians to ascertain the existence and extent of noncompliance in veterinary practice in lbadan and to elucidate the influence of such factors as logistics, education, economy, attitudes and veterinarian/client relationship on non-compliance. Analyses of the results showed that both groups veterinarians and their clients perpetrate non-compliance. Ignorance of the aims of treatment, financial constraint and negligence are factors that encourage non-compliance by pet owners. The results also showed that some veterinarians encourage non-compliance by not educating clients on their diagnosis, aims of treatment, and also by not given written instructions.

We conclude that non-compliance by pet owners to drug prescriptions exists in veterinary practice in lbadan. Veterinarians have a role to play in reducing the level of non-compliance by educating clients on proper drug use and consequences of non-compliance. An improved economy will assist both veterinarians and clients in fulfilling their individual responsibilities
