A feeding trial was conducted to assess the level of inclusion of high fibre sunflower seed cake (HFSSC) protein as ror soyabean cake protein replacement  for soybean cake protein in the diets of broiler chicken at 0,25,50,75, and 100%. At the starter phase feed intake and feed efficiency ratio were significantly (p,0.05) increased as the level of HFSSC increased in the diets . weight gain and protein efficiency ratio were however significantly (p,0.05) reduced when over 25% of HFSSC was included in the diets . Atthe finisher phase the same trend was observed except that weight gain and protein efficiency ratio were significantly (p0.05) reduced when over 50% HFSSC was included in the diet. Significantly (p<0.05) differences were observed in live weight, plucked and dressing percentages at the starter and finisher phases. Reduction in abdominal fat deposition was obtained at the starter and finisher phases while gizzard weights wee significantly (p<0.05) increased. The result of this study show that 50% soybean  cake protein in the diets of broiler chicken can be replaced by HSFFC.

An eight weeks feeding trial was conducted to assess the effect of feeding graded level of soaked pigeon pea meal (SPPM) in wood ash extract or solution on the growth performance, haematological and serum biochemical indices of broiler chickens. A total of 144 day-old chicks (Anak 2000) were randomly allotted to four treatment diets (1, 2, 3 and 4) in a completely randomized design. Each treatment group was replicated three times with twelve birds per replicate, thus, having thirty-six chicks per treatment group. Diet 1 contained 0% SPPM in wood ash extract for 72hours as the control diet, while diets 2, 3 and 4 were formulated to contain 25, 50 and 75% inclusions of SPPM in place of soybean meal. Results showed that the average live weight, daily weight gain and feed intake as well as protein efficiency ratio were significantly (P<0.05) influenced by the dietary treatments at the finisher phase. Broiler chickens fed 25% SPPM based diet had a higher (P<0.05) and comparable value of live weight, weight gain and protein efficiency ratio to that recorded in the control diet at the finisher phase. The haematological and serum biochemical indices revealed that albumin and total cholesterol were significantly (P<0.05) influenced by the treatment diets. The albumin value (2.2g/dl) was highest in birds fed 50% SPPM, whereas, the cholesterol value decreased (P<0.05) with increasing levels of inclusion of SPPM from 0 to 75%. It therefore implies that SPPM can be partially included in broiler diets up to 25% level with optimum growth performance and without any detrimental effect on the blood profile of broiler chickens.

The scarcity and increasing cost of conventional plant protein sources prompted researches into potential feed resources that are relatively of less importance to man. Loofah gourd (Luffa cylindrical (M.J. Roem) is a plant that is widely available in most tropical, subtropical and temperate region. In Nigeria it grows luxuriantly uncultivated and the sponge is often used for domestic cleaning while the seeds are discarded. The seeds were de-hulled, milled and fed at 0, 5, 10, 15, and 20% dietary levels of inclusion as partial total replacement for groundnut cake. One hundred and fifty (150) day-old broiler chicks were divided into five (5) groups and each was fed the experimental diets for fifty six (56) days in a completely randomised design (CRD) arrangement. Data collected included the average feed intake (AFI), average weight gain (AWG), live weight (LW) feed conversion ratio (FCR), protein efficiency ratio (PER), haematology indices such as pack cell volume (PCV), red blood cell count (RBC), white blood cell count (WBC) and haemoglobin (Hb), serological variables such as Alanine aminotransferase (ALT), aspartic aminotransferase (AST), alkaline phosphatase (ALP) and carcass characteristics. Loofah gourd seed meal (LGSM) significantly (P<0.05) depressed the feed intake, weight gain, live weight, and protein efficiency ratio of the birds as the dietary inclusion of LGSM increased in a similar trend. AFI, AWG, and PER were significantly highest (P<0.05) in birds on the control group (125.88 g/day, 51.37 g/day, and 1.81 respectively) and lowest in those on 20% LGSM (62.88 g/day, 19.35 and 1.39 respectively). PCV and Hb were significantly highest (P<0.05) in birds on the control group (10.46 g/dl and 34% respectively) and lowest in those on 15% LGSM (21%) and 10%LGSM (6.98g/dl) respectively. Birds fed with the control diet had the lowest (P<0.05) AST (86.13 U/I), ALT (5.67 U/I) and ALP (112,338.90) and those on 20% LGSM had the highest AST (104.18 U/), ALT (10.98 U/D while the highest ALP (201,762.90) was in birds fed 10% LGSM. Weight of liver and spleen expressed as percentage of live weight were significantly lowest in birds on the control group (1.38 and 0.18 respectively) and highest in those on 15% LGSM (4.08 and 1.50 respectively). The increase in liver and spleen weight coupled with increased serum enzymes activities suggest the presence of anti-nutrient in LGSM. Hence, the use of LGSM beyond 5% level of inclusion is not beneficial in the production of broiler.

An experiment was conducted to determine the dietary effect of different levels of ground black pepper (Piper nigrum) on growth performance and apparent nutrient digestibility of broiler chickens. There were five dietary treatments each containing 0, 0.25, 0.50, 0.75 and 1.00 % black pepper (BP) fed at both starter and finisher phases. One hundred and fifty (150) day old chicks of Arbor-acre strain were divided into five dietary groups having three replication with 10 in each. The five dietary treatments were randomly assigned into five groups. The birds were fed and watered ad libitum. At the starter phase 0.25 and 0.5 % BP improved live weight significantly (p<0.05). Feed intake was significantly (p<0.05) reduced at 1.00% BP. There were no significant differences (P>0.05) in daily gain, feed: gain ratio and protein efficiency ratio. At the finisher phase, final live weight was improved by 0.25% (p<0.05). Final live weight, feed intake, weight gain, feed: gain ratio and protein efficiency ratio were negatively affected by 0.75 and 1.0%BP. Fecal moisture was significantly (P<0.05) reduced by 0.25% while dry matter, protein and ether extract digestibility were improved by all the levels of BP. None of the BP levels improved crude fibre digestibility (p>0.05) over the control. NFE and energy utilization were improved by 0.25 and 0.5%, but significantly (p<0.05) reduced by 1.00% BP.Bang. J.

The performance and nutrient retention of broilers fed raw (RMD), toasted (TMD), boiled (BMD), soaked and boiled (SMD) or no (NMD) Mucuna cochinchinensis seed diets at both starter and finisher phases were assessed using 400 broiler chicks. The birds were fed a common proprietary feed (Top Feed) until 2 weeks of age, followed by a treatment diet for 3 weeks of the starter period, then 5 weeks on the finisher diet. At the starter phase, RMD significantly (P < 0.05) decreased liveweight, daily weight gain, protein efficiency ratio and encouraged poorer feed conversion ratio and higher cost per kilogram weight gain when compared with other diets. TMD decreased (P < 0.05) only the protein efficiency ratio. RMD also decreased (P < 0.05) retention of dry matter (DM), crude protein (CP), crude fibre (CF) and energy while TMD decreased (P < 0.05) retention of only DM, CP, and energy. At the finisher phase, RMD also significantly (P < 0.05) decreased daily weight gain, protein efficiency ratio and feed conversion ratio and increased cost per kg weight gain, while TMD decreased (P < 0.05) only the protein efficiency ratio and feed conversion ratio. RMD again decreased (P < 0.05) retention of DM, CP, CF and energy, while TMD, as in the starter phase, again decreased (P < 0.05) retention of DM, CP and energy. On a cumulative basis, RMD adversely affected (P < 0.05) all the parameters under investigation. TMD affected (P < 0.05) only the feed conversion ratio, protein efficiency ratio and cost per kg weight gain. Boiling Mucuna cochinchinensis, therefore, encourages significantly better performance of chicks, higher nutrient retention and lower cost per kg weight gain than toasting, whereas soaking before boiling does not add any advantage to boiling alone.

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB)  (T0), LPB+ 100g/100 met + 300g/100  lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.

Research aimed to determine broiler performance fed different level of yoghurt - fermented pineapple peel (FPPM) in the diet containing medicinal weed. Two hundred 2 day - old male broiler chicken, diet containing medicinal weed  (MW) and yoghurt - fermented pineapple peel used in this study. The experimental design was a completely randomized design with 5 treatments and 5 replications. The treatments were T0 (control, diet containing 0% FPPM and 0% MW), T1 (diet containing 0% FPPM and 2% MW), T2 (diet containing 7.5% FPPM and 2% MW), T3 (diet containing 15% FPPM and 2% MW), and T4 (diet containing 22.5% FPPM and 2% MW). The variables were feed consumption, body weight gain, live weight and feed conversion ratio. Data were analyzed by ANOVA and Contrast orthogonal Test. The results showed that there was a significant effect (P<0,05) of treatment on the feed consumption, body weight gain, live weight and feed conversion ratio. Feed consumption and feed conversion ratio increased with increasing level of FPPM in the diet, however, body weight decreased. It is concluded that feeding yoghurt - fermented pineapple peels up to 22,5 % in the broiler diet containing medicinal weed decreased broiler chicken performance.

Ompok Bimaculatus

The Indian butter catfish, Ompok bimaculatus (Bloch, 1794), is a high-value catfish that has gained immense consumer preference in South-East Asia. However, information on the nutritional requirements of this species is scanty. Hence, an experiment was conducted to evaluate the effects of varying dietary lipid levels on growth, body composition, and activities of digestive and metabolic enzymes in larvae. Three isonitrogenous (40% crude protein) diets were formulated by supplementing fish and vegetable oil (1:1) at 4.5% (D1), 7% (D2), and 9.5% (D3) levels (containing crude lipid 5.7%, 8.0%, and 10.45%, respectively in diets D1–D3) to a fish meal- and oilcake-based formulated diet. Experimental diets were fed to butter catfish larvae (0.15 ± 0.01 g) in triplicate groups for a period of 42 days. Proximate compositions of the experimental diets, as well as fish carcass, were analyzed using standard procedures (AOAC 2005). Digestive and metabolic enzyme activities were analyzed at the completion of the experiment by standard methodology. Butter catfish larvae fed the diet D2 (8% crude lipid) resulted in the best performance in terms of weight gain (final weight 1.40 ± 0.07 g), net weight gain (1.31 ± 0.06 g), specific growth rate (5.50 ± 0.05% · day−1), and protein efficiency ratio (2.39 ± 0.17). The highest lipid deposition (2.90 ± 0.12%) in the carcass was also recorded in fish reared on diet D2. The final weight, net weight gain, protein efficiency ratio, and specific growth rate were significantly (P &lt; 0.05) higher in D2 having 8% lipid. Moisture and lipid contents of the whole body were significantly (P &lt; 0.05) higher in larvae fed diet D2. Amylase activity in fish significantly (P &lt; 0.05) decreased with increasing dietary lipid levels. The maximum alkaline protease, pepsin, and lipase activities were noticed in the larvae fed diet D2. Progressive decrease in liver glucose-6-phosphate dehydrogenase activities and significant increase (P &lt; 0.05) in the activities of neoglucogenic enzymes (glucose-6-phosphatase and fructose-1,6-bis phosphatase) were noticed with an increase in dietary lipid levels. Significantly lower (P &lt; 0.05) activities of LDH, ALT, and AST were recorded in the group fed diet D2. Results of the study indicated that 8% crude lipid in the diet could assure optimum growth and survival of butter catfish larvae during early development. An appraisal on growth, body composition, and digestive as well as metabolic function in the butter catfish larvae recorded in the study might provide some important information to consider application of formulated diets for the larviculture of Ompok bimaculatus.
