“…This corroborates the report of Renema et al, (2008) who stated that small degrees of over or underfeeding have been shown to negatively impact egg production. However, this report contradicted the findings of Sekoni et al, (2002) who concluded that quantitative feed restriction did not have any significance on feed consumption and efficiency of feed for egg production. Differences in total egg production observed in this study shows that bird fed two times a day (morning and noon) had better egg production compared with those fed once and thrice a day.…”

Most poultry farmers in Nigeria feed their laying birds twice a day with one bag of 25 kg to 200 layers which translate to 125g/bird/day, while very few feed once or thrice a day and there has been little or no documentation on how many times laying hens should be fed in a day to optimize profit. Thus, this study was designed to investigate the performance and egg qualities of Isa-Brown layers fed different quantities of feed at varying feeding frequencies. Three hundred and sixty (360) 16-weeks in-lay Isa-Brown layers were used in this trial. The treatment consisted of 95g, 105g, 115g, and 125g of feed per day at varying frequencies of once, twice and thrice per day. The birds were housed in California type cages, 3 birds per cage unit, 5 cage units per replicate, and 6 replicates per treatment. A completely randomized experimental design with a 4x3 factorial was adopted. Results at the end of the trial showed that bird fed 115g of feed twice per day had the highest percentage hen-day production (85.24%), highest egg mass (56.69g) and best feed conversion ratio (1.96) while lowest percentage hen-day production (62.02%) and lowest egg mass (39.22g) were observed in hen fed 95g of feed thrice per day and worst feed conversion ratio (2.50) was recorded in bird fed 125g of feed thrice per day. The bird fed 115g twice per day had the highest net profit (N637.63) while the lowest net profit (N199.33) was recorded in bird fed 125g thrice per day. It could be concluded that for optimum laying performance and to save time and labour expended in feeding birds thrice per day, feeding laying Isa-Brown birds the required feed quantity (115g) twice per day would be most economical.

“…This result is contrary to that of Tumova et al (2002), who indicated that intake of feed decreased by restricted feeding, which brought about a better feed efficiency when compared with those under unrestricted feeding. The results of this work agree with the findings of Sekoni et al (2002), who showed that controlled feeding did not influence the feed conversion ratio of birds. Novele et al (2009) also showed that feed restriction at early age of birds for a short period stimulated compensatory growth so that at the market age feed restricted birds performed similarly to those of the full fed groups.…”

An eleven-month experiment was conducted to establish the influence of phenotype and feeding systems on growth performance and carcass characteristics of F1 crossbred broilers. One hundred normal feathered broiler breeder females were mated with 10 naked neck males to obtain the F1. Two hundred and seventy-two chicks obtained from the F1 generation and from four hatches were randomly assigned into four treatments (naked neck full feeding, naked neck feed withdrawal, normal feathered full feeding and normal feathered feed withdrawal) in an RCBD 2 × 2 factorial arrangement and studied for 12 weeks. The naked neck broilers had superior (P < 0.05) weight and better feed conversion compared to their normal feathered counterparts. Chickens on full feeding had higher (P < 0.05) feed intake in comparison to their counterparts on feed withdrawal. Normal feathered birds had higher (P < 0.05) average rectal temperature compared to the naked neck ones. Mortality was lower (P < 0.05) in naked neck birds compared to their normal feathered siblings. Birds on feed withdrawal had higher (P < 0.05) average rectal temperature in contrast to their counterparts on full feeding. The naked neck gene improves growth performance, carcass yield and survivability hence should be incorporated into broiler breeding programmes for tropical countries.

“…The average egg weights from dietary treatments with 25 and 50% urea-treated BDG which compared favourably with the control indicated that these replacement levels lied within the optimum range of inclusion for positive synergistic effects on egg weights. Average egg weights obtained in this study were comparable to that of Sekoni et al (2002) and Ayanwale et al (2003) who fed cottonseed cake to pullet layers. The similarity of the hen day production of birds fed the control and the urea-treated and fermented BDG diets up to the 75% inclusion level is an indication that these levels of inclusion furnished adequate nutrients to the birds to support same production level.…”

The effect of replacing groundnut cake (GNC) with urea-treated and fermented brewer's dried grains at 0, 25, 50, 75 and 100% graded levels in pullet layers diets was investigated. Five dietary treatments were formulated to be isonitrogenous and isocaloric to provide 17% crude protein and 2600kcal/kg metabolizable energy. One hundred and twenty pullet layers of Goldline hybreed were randomly allotted into five treatments of 24 birds each and replicated three times with 8 birds per replicate. They were fed ad libitum in deep litter for eight weeks. Daily feed intake, total eggs produced for the period, total eggs weight per bird and feed conversion ratio were not significantly (P>0.05) different, while significant (P<0.5) differences were observed in final body weight, body weight gain, total eggs produced per bird per week, average egg weight and hen day production. Hen day was similar for the control and up to 75% replacement level. It was more economical and profitable to use urea-treated and fermented brewer's dried grains in replacing GNC in pullet layer's diets.
