To contribute solutions to the problem of animal protein shortage for human consumption in Cameroon, a study was conducted at the Teaching and Research Farm of the University of Dschang- Cameroon to evaluate the effects of inclusion levels of Tithonia diversifolia leaf meal (TDLM) on growth performance and carcass characteristics of rabbits. The leaves were chopped, boiled for 5 minutes, drained, sundried, milled and analysed for proximate composition in the Laboratory of Animal Nutrition. The leaf meal was used to formulate 4 experimental diets containing 0% (control) 15, 20 and 25% of the TDLM, corresponding to T0, T1, T2 and T3, respectively. A total of 40 (20 males and 20 females) 2-months-old rabbits, weighing 1000 ± 125g were randomly assigned to the 4 dietary treatments in a 4 x 10 replicates in a completely randomized design. The live weights of the animals were evaluated weekly for 9 weeks. Eight (8) rabbits (4 males and 4 females) per treatment were randomly selected and sacrificed for carcass evaluation. The data collected were then submitted to one-way Analysis of Variance (ANOVA). Mean differences were separated using Duncan. The results showed that incorporation of TDLM induced a decrease in daily feed consumption. The least daily feed intake was observed in treatment T3 (109.14g/d) while the highest daily weight gain (24.49g/d) and the least feed conversion ratio (4.61) were also observed in the same treatment T3. However, no significant differences were observed for these parameters (P>0.05) between the treatments although daily weight gain was higher and feed conversion ratio lower in the males as compared to the females. Carcass yield (C.Y.) was higher in the control T1 (52.39%) though comparable (P>0.05) with all the other treatments. Abdominal fat was significantly (P<0.05) lower (1.90%) in the treatment T0 but it was comparable to T3 while it was highest (2.28%) in T2. However, C.Y. was higher in males and abdominal fat was higher in females when sex was considered. The relative weight of the lungs was highest in T1 (0.55%), liver in T2 (2.25%), kidneys in T1 (0.56%) and the heart in treatment T2 (0.25%) though, there were no significant differences (P> 0.05) observed in organs weights. Although there were significant differences between organs of different sexes, no regular pattern was maintained. These all signified nutritional adequacy at all levels of inclusion of TDLM, improving growth performance at the inclusion level of 25%. T. diversifolia leaves boiled for 5 minutes, sundried and milled can therefore be used as an alternative ingredient which when included in the rations of rabbits up to 25%, still compares well with conventional ingredients in growth and carcass performance irrespective of the sex. However, the use of TDLM could significantly reduce the cost of feeding and enhance meat production as it is relatively more abundant as compared to other ingredients.

 This experiment was conducted to determine the effect of dietary utilization of baobab leaf meal (BLM) on performance, carcass characteristics and hematological parameters of broiler chickens. Two hundred and twenty-five (225), one day old broiler chickens (Marshall Breed) were used for the study. Five diets were formulated containing baobab leaf meal (BLM) at dietary levels of 0, 2.5, 5, 7.5 and 10% designated as T1, T2, T3, T4 and T5 respectively. Chicks were randomly allotted to treatments in a completely randomized design (CRD) and each treatment was replicated three times consisting of 45 broiler chickens with 15 chicks per replication. The experiment lasted for eight weeks. Sample of BLM, experimental diet and faeces were analyzed for proximate compositions. Similarly, levels of anti-nutritional factors in BLM were also evaluated. The results at starter phase showed that the final body weight, daily weight gain and total weight gain were significantly (P < 0.05) higher at 7.5% BLM diet compared to other treatments. The feed conversion ratio (3.30) and feed cost in naira per Kg gain (N257) were significantly (P< 0.05) better at 7.5% BLM diet compared to others. The same trend was observed at finisher phase in the final body weight (2147.80g) and daily weight gain (52.39g). Similarly, feed conversion ratio (3.14) and feed cost in naira per Kg gain (N289.89) were significantly (P< 0.05) better at 7.5% BLM diet compared to other treatments. The results for carcass analysis showed that there were significant differences (P < 0.05) in final live weight (2.15 Kg) as broiler chickens fed 7.5% BLM diet had significantly (P< 0.05) highest values of carcass weight (1.52 Kg) and dressing percentage (72.04%). There were significant differences (P<0.05) in thigh muscle, back and small intestinal weights in which 7.5% BLM diet had the highest values across the treatments. Most of the organs weights were not significantly (P>0.05) affected by BLM inclusion with exception of crop and proventriculus. Therefore, it was concluded that BLM can be incorporated in the diet of broiler chickens up to 7.5% level without any adverse effect on the performance, carcass yield with concomitant reduction in the cost of production

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P &lt; 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P &lt; 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P &lt; 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

An experiment was conduted to evaluate the effectiveness level of corn substituted by Morinda citrifolia leaf meal in broiler ration. The use of Morinda citrifolia leaf meal substituted for corn in ration is expected to improve feed conversion in broiler chickens and produce chicken meat that safe for consumption and free of chemical antibiotics residues . Completely Randomized Design (CRD) was used to analyze data obtained from this research. One hundred and sixty chicleas (7 days aged) divided into 5 (five) treatments with 4 (four) replications and each replication consisted of 8 (eight) chicleas. Ration of treatments were a negative control diet (R0), 1% Morinda citrifolia leaf meal (R1), 2% Morinda citrifolia leaf meal (R2), 3% Morinda citrifolia leaf meal (R3) and commersial ration (R4). All treatments rations were added a natural feed additive that consist of 0,125% Curcuma and.0,075% Turmeric meal. Measured parameters were feed intake, weight gain, feed conversion ratio, mortality, percentages of carcas and abdominal fat. Results showed that feed consumption, weight gain, and feed conversion ratio were significantly (p <0.05) influenced by treatments. Mortality, percentage of carcas and abdominal fat were not significantly (p >0.05) influenced by ration treatments. Mortality rates in chickens using a ration of treatment was 0%, while using the control diet 0,78% (1 bird). The counclusion showed that the substitution of 1-2% Morinda citrifolia leaf meal in ration has better performance compared to the control diet, with improvement of feed conversion ratio was 7.57 and 9.2% respectively was more efficient than the control diets

Commercial Diet

The objective of this study was to develop the least-cost starter&rsquo;s diet and evaluated its effect on the growth performance of Sasso breeds and Indigenous ecotype of chicks under the local condition of the South Gondar Zone. The effects of substitution of different levels of commercial starters ration with homemade diet on the growth performance of Sasso and Indigenous chicks were studied in Hiruy Abaregay village of Farta district. The research area is 586km distant from the capital city of Addis Ababa, Ethiopia. A total of 510 Sasso T-44 and 90 Indigenous local ecotypes day-old chicks were randomly divided into five groups, each with 102 and 18 chicks, respectively. These were assigned into five treatments in which 100 (T1), 75 (T2), 50 (T3), 25 (T4), and 0% (T5) of commercial starter&rsquo;s diet in factorial completely randomized design (CRD) with 3 replications for 60 days feeding period. The results obtained indicated that increased levels of substitution of a commercial diet with a homemade diet significantly depressed (p&lt;0.001) mean daily feed consumption and retention of dry matter, nitrogen, and metabolizable energy. Growth rate as measured by mean daily weight gain, mean final body weight, and total feed consumption and feed cost were significantly miserable (p&lt;0.001) in an increased homemade diet. On the contrary, there was an increase in feed conversion ratio and fiber content in high-level dilution of starter&rsquo;s commercial diet with a homemade diet. However, the groups of chicks on 0, 25, and 50% commercial starters diets replaced by homemade diet were significantly higher (p&lt;0.001) in mean daily feed intake, daily weight gain, feed conversion ratio, and final body weight attained. The results of this study indicated that up to 50% of expensive commercial starter&rsquo;s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

A 56-day feeding trial using twelve (12) crossbred weaner pigs of 8 weeks of age and average weight of 10.58±17kg were used to investigate the effect of different dietary levels of raw bambara groundnut offal on their growth and carcass characteristics. Four diets were formulated to contain raw bambara groundnut offal at 0, 10, 20 and 30%, designated T1, T2, T3 and T4 respectively. The weaner pigs were randomly assigned to the four (4) diets in a completely randomized design (CRD) experiment. Chemical composition of the test ingredient and diets were analysed. Data collected include feed intake, weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and economics of production. The carcass characteristics were also evaluated. The proximate composition of the experimental diets revealed that the crude protein and ether extract contents of the diets decreased with increased levels of raw BGO in the diets, but the converse was true for crude fibre and ash contents. The results indicated significant differences (p< 0.05) in daily weight gain (DWG). feed conversion ratio, protein efficiency ratio, cost (N) /kg of seed and cost (N)/kg weight gain. The values were. 0.34, 0.29, 0.28 and 0.22kg for DWG, 3.03, 3.62, 3.55 and 4.30 for FCR in T1, T2, T3 and T4 respectively. Protein efficiency ratio, values were 1.84, 1.54, 1.57 and 1.29. Cost/kg of feed values were 75.69, 70.13, 64.56 and 56.10, and cost (N)/kg weight gain were 229.32, 253.86, 229.20 and 253.69 for the treatments respectively. The results of the carcass evaluation indicated significant differences (p< 0.05) for ham and trotters. The values were 0.31, 0.35, 0.37 and 0.32 for ham in T1, T2, T3 and T4 respectively. The values of trotters were, 64.6.56.99, 56.98 and 53.66 among the treatments. For organs characteristics, the results indicated significant differences (p< 0.05) for lung, kidney, liver and spleen. The values of the lungs were, 11.20. 11.25. 9.40 and 8.97 among the treatments. The values of kidney and liver were, 3.34, 2.86, 3.72 and 3.14, and 24.28, 28.57, 22.55 and 27.70 respectively. The inclusion of up to 20% raw BGO in the diet of weaner pigs recorded comparable daily weight gain, feed conversion ratio and cost/kg weight gain with the group fed the control (0%raw BGO). Further studies involving heat treatment of the BGO might be necessary to improved nutrient utilization by the animals, and also increase inclusion level.

The study was carried out to evaluate the effect of concrete feeding trough, semi-automatic feeder and their combination on growth performance of weaned pigs. Sixty weaned cross bred (Large white x Landrace) pigs of average initial weight of 9.04 Kg were grouped based on sex and assigned to three dietary treatments, comprising two replicates of 10 weaned pigs each. The design of the experiment was completely randomized design. A standard diet was prepared to meet the nutrient requirements of weaned pigs. The diet was fed to the animals in concrete feeding trough (T1), semi-automatic feeder and concrete feeding trough (T2) and semi-automatic feeder (T3). The experiment was partitioned into three periods (Weeks 1-4, 5-8 and 1-8). Feed and water were given unrestrictedly throughout the period of the experiment. The feed intake and weights of the pigs were recorded on weekly basis. Feed conversion ratio and daily weight gain were calculated and the study lasted for eight weeks. There was no significant (P>0.05) effect of feeders on final body weight, average daily weight gain, daily feed intake and feed conversion ratio. The overall performance showed that combination of the feeders (T2) improved daily weight gain (369.71 g), average daily feed intake (1021.14 g) and had the best feed conversion ratio (2.99). It could be concluded that combination of concrete feeding trough and semi-automatic feeders improved the growth performance of weaned pigs.

Apart from the use of sour sop (Annonamuricata) as food crop, the leaves, seeds andmany of the plant parts are used in traditional medicine for treatment of kidney problems, fever with antispasmodic, antidysenteric, and parasiticidal activity. Thus, a 63 day study was conducted to evaluate the feed potentials and effect of sour sop (Annona muricata) leafmeal (AMLM) on growth performance ofWest African dwarf (WAD) weaned goats. Nine (9)WAD goats were grouped into three and assigned diets containing 0%, 10%, and 20%Annona leaf meal.Formulated feedswere offered at3%of bodyweight in themorning andgmelina leaves later in the day. Feed intake was recorded daily while weight gain was taken weekly and feed conversion ratio was calculated to determine growth performance. Proximate composition of the leaf meal was determined according AOAC, (2000). The result showed high metabolisable energy, dry matter, ash, and crude fiber of 2563.5Kcal/Kg, 93.91%, 10.62% and 16.20% respectively,moderate level of nitrogen free extract (42.39%) and crude protein (20.41%) which is an indication thatAnnonamuricata leafmeal could be a suitable feedstuff for ruminant animals. The performance results showed that feed intake was significantly higher in group 1(0%AMLM) and lower in group 3(20%AMLM). However, no significant (P>0.05) differences were observed among the groups on weight gain and feed conversion ratio proving that the diet treatment had no significant effect on the goats. Therefore,Annona muricata leafmeal could be an alternative to high-cost goat nutritionwithout compromising growth performance.

The study was conducted to investigate the growth performance of broiler birds fed varying dietary levels of Artemisia annua. A total of 90 broiler chickens (Arbor Acre strain) were used. The study lasted for eight weeks. At the starter phase, 90 fourteen-day old broiler chicks were randomly allocated to five groups and fed starter diets containing five levels of A. annua (0, 50, 100, 150 and 200 g per kg of diet, respectively). At the finisher phase, 90 forty-two-day old finisher broilers were randomly allocated to five groups and fed finisher diets containing five levels of A. annua (0, 50, 100, 150 and 200 g per kg of diet, respectively). Each group was replicated three times with six birds per replicate in a completely randomized design. Parameter measured includes body weight, average daily feed intake, feed conversion ratio and protein efficiency ratio. The result of the proximate composition showed that Artemisia annua leaf meal contained 10.50% moisture, 26.27% crude protein, 5.00% crude fibre, 9.60% ash, 2.00% ether extract and 46.63% nitrogen-free extract. The result showed that at the starter phase, the inclusion of varying levels of A. annua in the starter diets had significant (p < 0.05) effect on the final body weight (FBW) of birds. Birds fed diet 2 (diet containing 50g of A. annua per kg diet) had significantly (p<0.05) higher final body weight (FBW) value (1115.00g) than those fed diet 5 (diet containing 200g of A. annua per kg of diet) which had FBW value of 915.00g. Dietary treatments had no significant (p > 0.05) effect on average daily feed intake (ADFI), total weight gain (TWG), average daily weight gain (ADWG), feed conversion ratio (FCR) and protein efficient ratio(PER) of the birds. At the finisher phase, significant (p < 0.05) differences existed among treatments in ADWG, TWG, FBW and ADFI. Birds fed diet containing 50 g A. annua per kg diet had significantly (p < 0.05) higher ADWG, TWG and FWG values than those fed the control diet. However, no significant (p > 0.05) differences existed among treatments in FCR and PER. It is concluded that A. annua leaf meal can be included in the diet of starter and finisher broilers at 200g per kg of diet without any deleterious effect on the growth performance of birds.
