Abstract: A study was conducted to evaluate the feeding value of ground nut cake (GNC) with concentrate feeds on milk yield and its economic feasibility. Changeover design was used in three periods each comprising 25 days plus the first seven days for adaptation and ten days for wash out of residual effect between consecutive periods. Treatment diet was ground nut cake (GNC) while soya bean meal (SBM) was used as control levelled at a ratio of 0 GNC: 100 SBM (T1), 50 GNC: 50 SBM (T2) and 100 GNC: 0 SBM (T3). The concentrate diets were maize, wheat bran, minerals and vitamin premix while basal diets grass hay and corn silage were fed ad libitum. Data were analysed using the General Linear Models procedure of SAS. Daily milk yield was higher (P<0.05) for T3 (18.71 l/d) and T2 (18.17 l/d) as compared to T1 (17.96 l/d). Milk yield differed (P<0.05) between treatments with stages of lactation. Economic analysis showed the highest net return for T3 and the lowest from T2. In general, Replacement of ground nut cake for soybean meal improved milk yield and economic return.

Abstract: The present study aimed to investigate the effect of earthworm supplementation on growth and egg production performance of layer chickens. A total of 96 layers were distributed randomly into four treatment groups with three replications using a completely randomized design. Feeding trial was started when layer were reach at 24 weeks ages. The experimental diets that containing 0 (Control), 0.66, 1.32 and 1.98 % of earthworm (EW) were fed to birds for the duration of twelve weeks. Eggs were collected daily and weighed in every week and then the egg production was calculated as %. Though, body weight measurement was taken at the commencement and at the end of the experimental period; whereas egg quality was evaluated at the middle and then in the last week of experimental period. Feed intake had not statistical difference among treatment groups. Chickens fed with both diets containing 1.32 and 1.98% of EW showed an increment in bodyweight change and egg production. The hen day egg production (HDEP) and hen housed egg production (HHEP) were significantly (P<0.05) higher for hens in T4 than others, but there was no significant (P>0.05) difference between T2 and T3. There was no measurable effect on egg quality due to feeding diets, containing earthworm. Supplementation of 1.98% earthworm in layer diets trigger egg production performances without affecting the quality eggs that starting from 24 week. It is concluded that earthworm supplementation has the potential to improve the egg production performance of laying hens.
