Cashew Apple

In this study, the effect of substitution of maize with fermented cashew apple residue (CAR) on the growth of broiler chicken was investigated. Cashew apple residue was subjected to fermentation with Lactobacillus plantarum, and then used to formulate broiler starter diet by substituting/mixing it with maize in the ratios 0:100, 50:50 and 100:0 for maize and CAR respectively. The diet was fed to four groups of day old broilers for six weeks during which feed intake and weight gained were monitored. The bacterial count increased from 5.6 × 106 at the beginning of the fermentation to 31.5 × 106 cfu/g at 72 hr. Also, the pH of the CAR was reduced gradually over the 72 hours period of fermentation coupled with increase in the total titratable acidity. The nutritional composition analyses of the compounded diets showed no significant difference (p≤0.05) between the crude protein content of the formulated feed (21.02±0.15 - 21.12±0.15%) and the commercially available feed (21.50±0.00). However, the crude fibre content of the control (3.10±0.00) was lower than the content of the formulated diets. After feeding the chicks for two weeks, there was no significant difference in the average weight gained by the chicks fed the control diet and those fed with fermented CAR-based feeds. The cumulative feed consumption in the groups ranged from 2.57 kg (diet C) to 2.91 kg (diet A). These results suggest that fermented CAR may be used as alternative to maize in broiler feed formulation

The blood profile and histology of selected tissues (kidney, lungs, intestine, and epididymis) of Balami Sheep fed Shea Cake meal supplement was investigated. A total of thirty-two (32) sheep of the average weight range of 11.75-14.75kg comprising an equal number (16) of males and females were randomly allotted to four dietary treatments in a completely randomized experimental design with eight sheep per treatment for twelve weeks duration. Treatment 1 (T1) was a control diet and had zero inclusion level of Shea cake meal (SCM), while treatments 2,3, and 4 had 10%,15%, and 20%  inclusion of SCM, respectively. At the twelfth week of the experiment, two blood samples of 5ml each were taken from each animal from the jugular vein. The first set was preserved in Ethylene Diamine Tetra Acetic Acid (EDTA) bottle for haematological parameters, while the second samples were preserved without EDTA for serum examination. Representative samples of tissues were randomly selected and slaughtered for gross microscopic examination. There was a significant difference (P<0.05) at various levels of inclusion for parameters investigated. The white blood cell (WBC), Red blood cell (RBC), and Packed cell volume (PCV) recorded the highest values at T3 (15% inclusion level) (13.42 x109/L), 2.92x1012/L, 3.75%, respectively). The serum parameters were significantly(p <0.05)different among the treatments. Total protein ranges from 54.78(mg/dl) (T1) - 60.51(mg/dl) (T2), Cholesterol70.15(mg/dl) (T1) - 78.00(mg/dl) (T4). Iron ranges from 58.15(ug/dl) (T1) - 62.88(ug/dl) (T3).The histopathology of tissues (kidney, lungs, intestine, and epididymis) showed no alteration across the treatments (P= .05) in the gross microscopic examinations. No lesion was observed in the lungs, kidney, epididymis, and intestine. The results showed that shea cake meal posed no health risk to Balami sheep and as such recommended as a good supplement in the diets of the sheep.

Clarias anguillaris fries were fed with three isoproteic (30.25%) and isoenergetic (1.42 MJ/Kg) diets to evaluate the effects of plant seed oil on the growth performance, feed efficiency and survival rate. The test was carried out on Clarias anguillaris with an initial average weight of 0.07 g distributed in 6 plastic tanks with a stocking density of 15 fries each. The treatments were in duplicate for 45 days. The results of this experiment showed that the fish fed diet B containing Adansonia digitata seed oil as a source of lipid has the best total average weight gain (AWGa) (0.15g) compared to those fed with P and S diets containing fish oil and the Balanites aegyptiaca seed oil respectively. Similar results were obtained with the specific growth rate, which showed a significant difference between the fish fed with B diet and those fed with S and P diets that do not differ significantly between them. The best feed conversion rate (FCR) was obtained with the fish fed with B diet, which showed a significant difference with the fish fed with P and S. The best survival rate (SR) of 80% was obtained with the fish fed with diet B, followed by 73% in fish fed with diet S, and finally the lowest value 67% was contained in the fish fed with the control diet P. The best protein efficiency ratio (PER) was obtained with the fish fed with diet B (1.16) followed by the fish fed with diet S (0.80) compared with the fish fed with the control diet P (0.74). From the results of this study, we can say the replacement of fish oil with Balanites aegyptiaca seed oil and Adansonia digitata seed oil has no negative impact on the growth of Clarias anguillaris fries. In conclusion, diet B containing Adansonia digitata seed oil appears to be more suitable for Clarias anguillaris fry growth.

Three trials were conducted to evaluate the potential of cassava (Manihot esculenta) foliage (leaves and petioles) as a protein supplement for sheep. In the first trial, nylon bag degradability of cassava foliage was studied. Proximate analysis of cassava foliage was conducted before and after the incubation. Rumen Ammonia Concentration (RAC) and pH were determined at 0, 4 and 8 hours after feeding cassava foliage diet (30%). Proximate composition of sundried cassava foliage was (%) DM 91.25, CP 18.55, NDF, 31.41, ADF, 29.2, EE, 6.6, Ash, 12.95. Nylon-bag dry matter disappearance (DMD) increased significantly (P<0.05) from 15.75% to 75.5% RAC values increased significantly from 8.20mg NH3/100ml at zero hour to 11.41mg NH3/100ml at 8 hours post feeding. Rumen fluid pH was not significantly changed by the 30% cassava foliage diet. In the second trial lasting 56 days, twenty-eight Yankasa/ WAD yearling rams of initial average weight of 18kg were balanced for weight and randomly allotted to seven treatments. All rams except those on control diet were fed cassava foliage or groundnut haulms or both at 1.0% or 1.5% of body weight (BW) as supplements to a basal diet of Gamba hay. Feeding Gamba hay alone (control) resulted in weight loss (-30.5g/day) but with cassava foliage or groundnut haulms supplementation at 1.0% BW, significantly higher gains of 39.2 and 44.6g/day were achieved respectively. At 1.5%BW level of supplementation with cassava foliage or groundnut haulms higher weight gains of 41.2 and 51.7g/day were achieved while feeding the (50.50) combined supplements at 1.0 and 1.50% BW resulted in live weight gains of 65.1 and 69.3g/day respectively. The third trial consisted of a four week grazing trial followed by a metabolic study. Twenty-one Yankasa/WAD yearling rams were randomly allotted to seven treatments and were balanced for live weight. All rams were allowed to graze standing digitaria hay as basal diet, except the rams on control diet. Those on treatment were fed cassava foliage or groundnut haulms or a (50:50) combination of both at 0.5% and 1.0% (BW). The metabolic study consisted of a seven day adjustment period and a seven day total collection period. There was no significant difference (P>0.05) in the live weight gains of rams on the control diet compared with those supplemented except for those supplemented with cassava foliage and groundnut haulms combined at 1% level where the weight gain was significantly higher (P<0.05). Feed intake was not significantly (P>0.05) affected by feeding either supplement. Supplementing digitaria hay with cassava foliage at both 0.5% and 1.0% BW did not significantly increase the nitrogen retention values, but groundnut haulms supplemented at 1.0% BW significantly (P<0.05) increased the nitrogen retention values.

To investigate the effects of replacement of fish oil by a mixture of Balanites aegyptiaca and Adansonia digitata seed oils three isonitrogenous (35.36%) and isoenergetic diets (3.48 MJ / kg) were formulated for one kilogram (1kg). The study was carried out on fries Clarias anguillaris for six weeks.At the beginning of the experiment, 90 Clarias anguillaris of the initial average weight of 0.82 ± 0.055g were randomly divided into three different groups with two replicates containing 15 fish/each. Fish were kept in six plastic tanks (50 x 40 x 30 cm) container (50 L). The results showed that the substitution of fish oil by a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil gives growth for all diets. However, the best growths are obtained from all points of view (MWGr, MWGa and SGR) with diet A (mixture of Adansonia seed oil and Balanites seed oil at a ratio of 20 : 20) followed by the diet D (mixture of Adansonia seed oil and Balanites seed oil at 10 : 30) compare to the control diet M containing fish oil. The best FCR was observed with the diet A followed by the diet D compare to the FCR observed with the diet M. The PER was higher in diet A (0.57) followed by diet D with (0.45) that has no significant difference with the control diet M (0.43). The highest value 63% was obtained with the diet D followed by 60% with the diet M and finally the lowest value 53% was obtained with the diet A. In regards to the growth performance, fish fed a 100% vegetable oil diet showed the best growth performance. Therefore, the replacement of fish oil with a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil has no negative impact on the growth of Clarias anguillaris fry. It would be interesting first to study the inclusion rate of Balanites aegyptiaca seed oil for a partial replacement of fish oil.

L-carnitine as well as lysine and methionine are amino acids of important nutritional and nutraceutical interest and are used in nutritional strategies as dietary supplements to improve feed quality characteristics in animals and broiler chicken in particular. This study investigated the effect of different levels of L-carnitine and extra levels of lysine-methionine on growth performance, carcass characteristics, and some immune system markers. Two hundred seventy male Ross 308 broilers were a fed control diet (C) and eight different diets supplemented with an excess of amino acids. In the experimental diets, identified as D1, D2, D3, D4, D5, D6, D7, and D8, extra L-carnitine, lysine, and methionine were added in excess with respect to the American National Research Council (NRC) recommendations: L-carnitine equal to NRC (D1), control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine equal to NRC (D2), control diet supplemented with lysine equal to NRC, methionine equal to NRC, and L-carnitine at 15% in excess of NRC (D3), control diet supplemented control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 15% in excess of NRC (D4), control diet supplemented lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 15% in excess of NRC (D5), control diet supplemented with lysine equal to NRC recommendations, methionine equal to NRC recommendations, and L-carnitine at 75% in excess of NRC (D6), control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 75% in excess of NRC (D7), and control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 75% in excess of NRC (D8). During the starter and growth phases, feed intake was not affected by dietary treatment (p > 0.05). By contrast, body weight and FCR were both affected (p < 0.001) during the starter period. During the finisher phase, feed consumption was affected (p < 0.05) by dietary treatment. Feed intake of broilers fed on C, D3, D6, and D7 were statistically similar (p > 0.05) (1851.90, 1862.00, 1945.10, and 1872.80 g/pen/day, respectively) and were higher (p < 0.05) than 1564.40 g/pen/day (D5). With the exception of drumsticks, neck, back thoracic vertebrae, and proventriculus weights, the economical carcass segments were not affected (p > 0.05) by the dietary supplementation of amino acids. Duodenum and ileum weights and lengths decreased with amino acid supplementation (p < 0.05). IgT and IgG titers against Sheep Red Blood Cells (SRBC) for both primary and secondary responses were not affected by dietary treatments (p > 0.05). Dietary amino acids supplementation did not affect IgM titer after the secondary challenge (p > 0.05) and had a significant effect (p < 0.05) on serum antibody titers in broilers vaccinated against Newcastle disease (NCD) and Gumboro ‘s disease at the 27th and 30th days, respectively.

Aim: The aim was to evaluate the chemical, physical, sensory and microbial qualities of fruit bars produced from blends of banana and cashew apple fruits and to investigate the applicability of cashew apple in fruit bar production. Study Design: The experimental design used was the complete randomized design (CRD) and the data obtained were analyzed using one – way analysis of variance (ANOVA). Place and duration of Study: The study took place at the Department of Food Science and Technology, University of Nigeria, Nsukka between January and July, 2016. Methodology: Fruit bar samples were prepared with blends of  ripe banana and cashew apple purees in the ratios of 90:10, 80:20, 70:30, 60:40, 50: 50% (Banana puree : Cashew apple puree). One hundred percent (100%) banana pulp based fruit bar served as the control. Formulated fruit bars contained 7% sugar, 5% date powder, 0.2% sodium metabisulphite and 0.5% citric acid in 1000 g of fruit purees and dried at 80oC for 8 hours. Fruit bar samples were analysed for sensory qualities, proximate composition, micronutrient compositions (vitamin C and potassium), physicochemical properties (pH, brix and titratable acidiy), and microbiological quality using standard methods. Results: There were significant (p<0.05) differences in the proximate composition, potassium, vitamin C and tannin content of samples. The carbohydrate, protein, crude fibre, ash and moisture contents ranged from 68.78 to 74.51%, 3.06 to 3.38%, 1.00 to 2.05%, 2.33 to 2.76% and 18.92 to 22.64% respectively. The fruit bars have high caloric energy values. The vitamin C content increased as the ratio of cashew apple increased. Potassium and tannin contents of the samples ranged from 125.50 to 220.00mg/100g and 52.04 to 84.23 mg/100g respectively. Titratable acidity, pH and brix of samples varied significantly (p < 0.05) and ranged from 0.23 to 0.37%, 4.00 to 4.65% and 7.10 to 11.85% respectively. The microbial results showed that total viable count found present in the fruit bar samples ranged from 4.0 x 102 to 1.3 x 103 while the mould count ranged from 2.0 x 101 to 7.0 x 101. The sensory scores showed that all samples were generally accepted while the sample with 20% of cashew apple was the most preferred. These results showed that underutilized fruits such as cashew apple can be utilized in this regard instead of being wasted.

This study was carried out at Poultry Research Station, State Board of Agricultural Research, Ministry of Agriculture for the period from 27 September 2014 to 9 November 2014 to evaluate the Supplementation of different levels of Conjugated Linoleic Acid (CLA) on productive performance of broiler. Four hundred eighty chicks (Ross-308),one day old were randomly distributed to four dietary treatments for 42 days of age with 3 replicates/vtreatment (40 bird/replicate). Experimental treatments were as follow; T1 (Control diet) without supplement, while the treatment T2,T3 and T4  were Supplemented with 1, 1.5, 2 g CLA /kg diet  respectively. The results showed significant (P ≤ 0.05) increased in mean of body weight, weight gain, average feed consumption and the feed conversion ratio, for the birds of treatments T3 and T4 in comparison with control treatment (T1). A     significant (P ≤ 0.05) improvement was found in dressing percentage of treatments T3 and T4  in comparison with control treatment, whilst the breast percentage was significantly higher in all treatments which supplemented CLA than T1 treatment. The liver percentage weight has significantly (P ≤ 0.05) increased whereas the abdominal fat percentage has significantly (P ≤ 0.05) decreased in treatment T4 in comparison with control treatment. It is concluded that CLA supplementation at levels 1.5 and 2 g/kg diet of broiler chicken has improved productive performance.

An experiment was conducted for a period of 56 days with 36 healthy New Zealand White (NZW) rabbits aged about one months having weight from 370 to 390g to evaluate the effects of dietary citric acid on growth performance, feed consumption and digestibility of nutrients as well as immune status. The experiment was designed with 6 dietary treatments having 6 rabbits per treatment. Rabbits of control treatment (T1) were given the diet without citric acid (CA) but the dietary treatments T2, T3, T4, T5 and T6 contained 0.5, 1.0, 1.5, 2.0 and 2.5% CA respectively. Green grass was supplied on ad libitum basis. The total body weight gain was Addition of CA at the level of 2% enhanced body weight significantly (P<0.05). (P<0.05)(P<0.05) T 734, 776, 812, 862, 911 and 740g for the rabbits fed 0, 0.5, 1.0, 1.5, 2.0 and 2.5% CA containing diets respectively. Total DM intake also increased with increasing the percentage of CA up to 2% level . Incase of feed conversion ratio, there was no significant difference in addition to different levels of CA. Supplementation of CA improved dry matter, crude protein and ether extract digestibility but incase of crude fiber and nitrogen free extract, there was no significant difference. Non significant difference was also found incase of acidity of feed and feces. The highest lymphocyte (73%) was counted in dietary treatment T6 having 2.5% CA, which was 17% higher than the control diet. From the result of this experiment, it may be concluded that the addition of CA up to 2% level in diet improves performance, digestibility of nutrients and immune status of growing rabbit.

Protein Components

The main aim of this experiment was to verify the suitability of two Polish varieties of dehulled lupin seed (the low-protein SONET variety and the high-protein JUNO variety) as protein components to replace 50% of soya extract meal in feeding mixtures designed for the feeding of young broilers. The results of this experiment demonstrate that suitable treatment of lupin seed (dehulling) may significantly increase its nutritional value. Dehulling provides a product (core) in which the level of nitrogen-containing substances is by 27% higher than that in the original seed, providing an important protein component to be added in feeding mixtures for chickens. The experiment has also shown that production performance depends on the particular Lupinus variety used. Chickens fed on the JUNO variety seed (Group E1) reached a live weight of 2.332 kg on Day 40, which is comparable with the control group of chickens (2.337 kg; Group C). However, chickens in Group E2 fed on the SONET variety seed had a conclusively lower average weight (2.280 kg) (P < 0.05). Feed consumption per kg of weight gain at this level of average live weight was as follows: 1.89 kg (Group C), 1.85 kg (Group E1), and 1.93 kg (Group E2). The results confirm the suitability of dehulled lupin seed as a substitute for soya extract meal. When designing the composition of feeding mixtures one has to know the exact nutritional composition of the particular lupin variety. One important finding from a nutritional point of view is that the seed of the Lupinus genus is a major source of the amino acid arginine, which is often deficient in the feeding mixtures.
