“…The SGR range of 4.01 to 4.35 (%/day) recorded in the study is significantly greater than the range of 2.71 to 3.19 (%/day) reported by Agokei et al (2010) and 2.30 to 2.84 (%/day) reported by Odulate et al (2014) for juveniles of the same species. This disparity could be attributed to variability in diets used and study duration.…”

“…Also the difference in SGR could be attributed to the difference feeding frequency used. The three times feeding per day used in this study was more appropriate (Aderolu et al, 2010); when compared to the one and two times used by Agokei et al (2010) and Odulate et al (2014), respectively. This study recorded better weight gain in the treatment that Values on the same row with the same superscript are not significantly different was administered more of the daily ration in the evening compared to the treatment where equal rations were fed to the fish.…”

African catfish Clarias gariepinus (Burchell, 1882) constitutes a bulk of farmed freshwater fish, particularly in Africa. Its optimal production relies on an optimal feeding regime as feed covers about 50% of operation cost. Studies on feeding regimes have mostly been on feeding frequency and the daily required rations. This study was therefore designed to evaluate the impact of varied proportions of normal daily rations on the performance of C. gariepinus juveniles. Clarias gariepinus Juveniles of 17.6 ± 3.7 g were stocked at a density of 15 juveniles per 50 L of water in 80 L plastic tanks and cultured indoors for 42 days. They were fed a standard specific feed at 5% total biomass three times daily (8:00, 13:00 and 18:00). Treatment 1 received 33.33% of its daily ration at each feeding period, while treatments 2 and 3 received (50%, 25% and 25%) and (25%, 25% and 50%) of the daily rations at 8:00, 13:00 and 18:00, respectively. Fish biomass and survival rate were determined weekly and individual fish weights and lengths were determined at the end of the experiment. Water was aerated continuously and half the volume was renewed daily; temperature and pH were monitored twice daily. The specific growth rate, weight and length gained were best in treatment 3 although not significantly different (p>0.05) among treatments. However, feed conversion ratio and condition factor in treatment 3 were significantly (p<0.05) better when compared to treatments 1 and 2 although temperature and pH in the different treatments were not significantly different (p>0.05). The estimated investment cost was 3891, 4136 and 3907 FCFA, with profit index of 0.95, 0.87 and 1.09 in treatments 1, 2 and 3, respectively. Therefore, administering about 50% of the daily ration in the evening as was the case in treatment 3 is more profitable in the culture of C. gariepinus juveniles.

“…The result from this study was also in agreement with the observation by Paguia et al (2014) who established that using different amounts of Moringa oleifera leaf meal (0 %, 0.2 %, 0.3 %, 0.4 %, 0.5 %) in broiler and layer ration, did not significantly influence the broiler' feed intake, weight gain, final body weight and FCR, and also had non-significant effects on feed consumption, FCR and egg production in layer chickens. It seemed that the incorporation levels of leaf meals did not affect the palatability of the diets (Odulate et al, 2014). Nguyen Thi Thuy and Ogle (2005) also suggested that the lack of effect of the green feeds on growth rate, feed conversion and meat quality was probably due to the fact that the basal diet was already well balanced in major nutrients.…”

“…Similar observation by Tagoe et al (2014) who reported that broiler offered Alternanthera sessilis leaf meal supplement at 0.5 % level of inclusion compared favourably with the control, while high levels (0.75 %, 1 % and 1.25 %) supplementation had negative effect on growth performance. The lower growth response was probably caused by reduced palatability of the diet which causes reduction in feed intake (Odulate et al, 2014). Ghazalah and Ali (2008) who suggested that the decrease in growth as dietary leaf meal increased could be caused by the high crude fibre content in particular cellulose from the cell walls of leaf meal, which may impede the utilization of nutrients by chicks.…”

“…Ipomoea aquatica is commonly called water spinach or morning glory and is highly invasive in several parts of the world, forming dense mats over the surface of water bodies such as lakes, ponds, canals and ditches (Igwenyi et al, 2011). Water spinach is found growing wildly in tropical and subtropical countries, and is cultivated widely in China, Indonesia, Thailand, Vietnam, Myanmar, Philippines, Bangladesh, and in India (Odulate et al, 2014). It is a good source of protein on dry matter basis (Men et al 2000), and also rich in minerals and vitamins, especially vitamins A (carotene), B1, B2, C and iron (Oomen and Grubben 1978;Naren Toung et al, 1994).…”

This experiment was conducted to study the effects of supplementing green feed-water spinach (Ipomoea aquatica) to basal diet on growth performance and nutrient digestibility of broiler chickens. A total of 120 male Cobb 500 broiler chickens aged 21 days were randomly allocated to three dietary treatments by using a randomized complete block design (RCBD). Each treatment consisted of five replicates and eight birds per replicate. From 22-49 days, the grower chickens were exposed to the three different experimental diets: diet 1-basal diet containing 0.4 % vitamin-mineral premix (control), diet 2basal diet containing 0.2 % vitamin-mineral premix + 34.5 g fresh water spinach (Ipomoea aquatica), and diet 3-basal diet without vitamin-mineral premix + 69 g fresh water spinach. Growth performances were measured and calculated on weekly basis. On day 49, three birds of each treatment group with almost similar body weight were selected and placed in individual cages. Feed intake was recorded for each bird every day and total faeces were collected on three consecutive days. In order to calculate the digestibility value of experimental diets, the dry matter (DM) and crude protein (CP) content of feed and faeces were determined. There were no significant effects on growth performances through feed consumption, body weight, weight gain and feed conversion ratio (FCR) of broiler chickens. The digestibility of feed DM and feed CP was not significantly different (P>0.05) among the treatments. Further, diets supplemented with water spinach had no adverse effect on growth performance and nutrients digestibility of broiler chickens. It can be concluded that the more expensive vitamin-mineral component of the ration can be replaced by the lower cost and widely available water spinach.

The use of alternative feeds aims to maintain productivity and reduce animal production costs. The objective of this study was to determine the nutritional value of Water Spinach (WS) (Ipomoea aquatica), as well as replacement of fishmeal (FM) by water spinach in diets for Nile tilapia fry, Oreochromis niloticus. To determine the growth performance of Nile tilapia fed different levels of water spinach, 150 fish (3.25±0.44g; 3.6±0.2cm) were randomly distributed in flow through system of 15 plastic aquariums each containing about 20 liters, and fed during 7 weeks with isoprotein (30% digestible protein) and isoenergetic (14.35 kJ g-1 digestible energy) diets containing replacement levels of 0, 25, 50, 75 and 100% of FM digestible protein by WS digestible protein. The experimental design was completely randomized with five treatments and three replicates. The protein efficiency ratio, absolute body weight, live weight gain and feed conversion ratio content significantly decreased in fish fed diets containing WS levels above 25%. Therefore, WS can replace up to 25% of FM without impairing juvenile Nile tilapia growth performance, feed efficiency, and body composition.
