A trial was carried out to evaluate the effect of replacing wheat offal with rumen content on the growth performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks were randomly allotted to five (5) dietary treatments containing 0, 5, 10% inclusion levels of sundried rumen content and 5 and 10% inclusion levels of roasted rumen content as a replacement to wheat offal. Each treatment was replicated three times with five (5) birds per replicate in a completely randomized design experiment. The trial lasted for eight (8) weeks. The results showed that there were no significant differences in the final weights, daily feed intake, daily weight gain and feed conversion ratio at the starter phase and finisher phases. Furthermore, no significant differences in the final weight (1346.60-1508.50g), daily feed intake (83.57-100.00g), and daily weight gain (36.43-39.53g), and were observed for the overall performance. However, there was a significant difference (P<0.05) in the feed conversion ratio with the highest being 2.69g and the lowest 2.33g in the overall performance. From these findings, it could be concluded that rumen content could replace wheat offal without any detrimental effect on the performance of broiler chickens.

Dietary Copper

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.

Feed Conversion

One method of reducing feed cost is to restrict the feed in the early life of broilers. In this regard, Fontana et al. (1992) reported that early feed restriction programs in their experiments proportionally reduced the consumption of the starter diets by an average of 22% in restricted broilers when compared with controls. Energy restriction has also been shown to result in a reduction in metabolic energy loss leading to a reduced requirement for maintenance. If during refeeding, this low requirement is maintained and if growth resumed at a normal or above normal rate (compensatory growth), feed efficiency would be substantially improved, leading to an economical advantage. This experiment was conducted to determine the effect of severity of diet dilution (energy and protein) and duration of early feed restriction on feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) of male broiler chickens.

This study was designed to evaluate the effect of different levels of raw and cooked turmeric rhizome (Curcuma longa) on the performance of starter broiler chicks in a complete randomised design. Turmeric rhizome was washed with water and divided into two batches of 20kg each. The first batch was crushed, then sundried for 3 days. The second batch was cooked for an hour, crushed with a roller and sundried for 3 days. Both the raw and cooked sundried turmeric rhizomes were then ground using a hammer mill to produce raw and cooked turmeric rhizome meal and were bagged respectively. Seven (7) broiler starter diets were formulated to contain raw or cooked turmeric rhizome meal at 0% (control diet), 0.5%, 1.0% and 1.5% levels, respectively. The diets were offered ad libitum to 189 Cobb broilers which were randomly divided into 7 dietary treatment groups, each containing 3 replicates of 9 birds per replicate. The experiment lasted for 21days. All the routine management practices were duly observed. Daily weight gain, daily feed intake, mortality and feed conversion ratio were used as criteria of response. The results indicated that addition of turmeric rhizome meal had no significant (p>0.05) effect on daily weight gain, daily feed intake, mortality and feed conversion ratio as compared with the control. It was evident that the different processing methods and the dietary levels used had no effect on broiler performance based on the results obtained in this study and within the circumstances of the experiments. It can be concluded that sun-dried raw and cooked turmeric rhizome meal at the dietary levels used did not significantly affect broiler starter performance.

This study evaluated the effect of aqueous extracts from cocoyam leaf on the growth performance of broiler chickens fed full-fat Soya bean. The study was carried out with seventy-two (72) day old broiler chickens in a completely randomized design. The seventytwo (72) broiler chicks were randomly assigned into four groups (T1, T2, T3 and T4), each treatment had (3) birds per replicate. The T1 which was the control, contained 0g of aqueous extract of cocoyam leaves while the birds in T2, T3 and T4 were offered aqueous extract of cocoyam leaves at 100g, 150g and 200g per 6 liters of water, respectively. The test ingredients were analyzed for nutritional and phytochemical composition. Data was collected from the broiler chickens' daily feed intake, feed conversion ratio, specific growth rate, body weight gain and daily weight gain. There were no significant differences (P>0.05) on the feed intake, daily weight gain, feed efficiency, feed conversion ratio, initial and final body weights of the broiler birds. However, total water and mean daily water intake differed significantly (P>0.05). The extract administered groups (T2, T3 and T4) had lower water intake as the quality of cocoyam leaves increased. The significant variations in the water intake as the quantity of cocoyam increased may be attributed to anti-nutrient factors (tannins) found in the leaves. The cocoyam leaves are rich in nutrients when assessed by the proximate and mineral composition. It can serve as a feedstuff for livestock. Cocoyam leaves extracts should be used with caution due to the anti-nutritional factors present in it. It is therefore safe to recommend 100-150g of cocoyam leaves/ 6litres of water for broiler chickens without any negative impact on growth rate of the broiler chickens.

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.

 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 present study was to investigate the short-term and long-term effect of the peripheral administration of ghrelin on the growth performance (feed intake, weight gain, and feed conversion ratio), carcass quality, and selected serum biochemical (glucose, total cholesterol, triglyceride, and total protein) and hormonal (T3, T4, and corticostrone) indices in broiler chickens. 240 one-day-old broiler chickens were selected, and allocated into three treatment groups (control and two experimental groups). On day-21 of the rearing period, ghrelin was peripherally administrated to three experimental groups. The control group contained birds without any administration of peptide or solution, groups G50 and G100; included birds with Ip-injection of 50 and 100 (ng/100g BW) ghrelin peptide, respectively. The peripheral administration of exogenous ghrelin did not affect feed intake, body weight gain (BWG), feed conversion ratio (FCR) and carcass characteristics in broiler chickens. In short-term samples taken 12h after ghrelin infusion, the glucose level was increased in ghrelin-treated groups (162 and 151 mg/dl in G50 and G100 compared with 117 mg/dl in control; P< 0.01) and there were significant declines for TC, triglyceride, and TP in the ghrelin-treated groups (G50 and G100) compared with the control. In addition, long-term glucose level has a greater value in G50 and G100 (182 and 200.66 mg/dl) compared with control (133.60 mg/dl) group (P< 0.01). A significant decline was also observed for TC and triglyceride content in the ghrelin-treated groups (P<0.05). There was no significant difference among groups for TP in short-term and long-term samples. There was a significant increase for T4 in ghrelin-treated groups (G50 and G100) compared with the control (4.55 and 4.57 ng/ml vs 4.20 ng/ml respectively; P< 0.05) in long-term samples. In conclusion, the peripheral administration of ghrelin in broiler chickens, during the commercial rearing period did not affect the overall growth performance, carcass quality and feed conversion ratio. The infusion of exogenous ghrelin may increase the levels of serum glucose, decrease total cholesterol and triglyceride, and T4 levels are increased in the long-term (and not in the short-term or 12h after administration).

An experiment was conducted to determine the growth response of African giant land snail Archachatina marginata fed diets containing different levels of sodium chloride. One hundred and twenty snails were subjected to four dietary treatments of T1, T2, T3 and T4 with 0%, 0.25%, 0.5% and 0.75% sodium chloride respectively. The treatments were replicated thrice with 10 snails per replicate. The measured parameters included weight gain, feed intake, shell length, shell circumference and shell thickness. Feed cost, cost of feed per kg weight gain and feed conversion ratio were also calculated. Results showed that there were significant differences (p < 0.05) in average daily weight gain, average daily feed intake, feed conversion ratio, feed cost and shell thickness but there were no significant differences (p > 0.05) in cost of feed per kg weight gain, shell length and shell circumference in the snails fed the treatment diets. Treatment 2 had the highest average daily weight gain (0.07±0.01), average daily feed intake (0.91±0.08) and feed cost (7.19±0.64) but the lowest feed conversion ratio (13.15±61.76) while treatment 1 had the lowest average daily weight gain (0.04±0.01), average daily feed intake (0.70±0.20) and feed cost (5.54±0.18) but the highest feed conversion ratio (15.86±0.5). This shows that inclusion of sodium chloride above 0.25% in the diet of Archachatina marginata affects both the feed intake and weight gain of the snails.

Energy is an important component of diets without which animals will not grow. Thus, a study was conducted to investigate the effect of low dietary energy on growth performance of broiler chicken at finisher stage. Two hundred and twenty five Zartech strain day old chicks were raised intensively for four weeks in a completely randomized design. The birds were grouped into three treatments of 75 birds and sub-divided into three replications of 25 birds. Three experimental diets of three energy levels (2,400; 2,600 and 2,800 ME Kcal/Kg designated A, B and C, respectively) with 20% crude protein were formulated and fed to the broiler chickens to assess feed intake, body weight gain, feed conversion ration and feed cost gain ration. The data were subjected to one way analysis of variance and means were separated using least significant difference. Results showed that feed intake decreased as the energy value of the feed increased. There was significant (p<0.05) difference in total feed intake between the treatments. No significant (p>0.05) difference was recorded in terms of initial live weight, final live weight, feed conversion ratio, feed conversion efficiency, feed cost and cost/gain. Feed cost showed progressive increase as the energy level of the diet increased. Lowest cost/gain ratio was reported from diet C. It was concluded that feed intake decreased as the energy value of the feed increased. It is therefore, recommended that broiler chickens should be fed with diet containing 2 800 ME Kcal/Kg as it provides the least feed conversion ratio.
