The objective of the current study is to assess the effects of the inclusion of 6-n phytase to a phosphorous-deficient diet on the growth performance (feed intake, average daily gain, and feed conversion ratio), apparent digestibility of calcium and phosphorus, and bone characteristics of grower–finisher pigs. The experimental diets included a phosphorus-deficient diet containing 0 (negative control), 250, 500, 1000, or 1500 FTU/kg of 6-phytase, and a diet formulated to meet the phosphorus nutrient requirements of pigs (positive control). Pigs were fed the experimental diets from the time they were ~35 kg body weight until they reached slaughter weight of ~110 kg. Bone status of the metacarpal (ash, mineral content) and femur (mineralization, geometry, and mechanical strength) bones were assessed. There was no effect of dietary treatment on feed intake. Feed conversion ratio was improved following inclusion of phytase at a dose of 500 FTU/kg or higher. Phytase inclusion at a dose of 1000 FTU/kg increased the average daily weight gain of grower–finisher pigs. Phytase inclusion at a dose of 500 FTU/kg was sufficient to increase metacarpal phosphorus content. Femur mid-diaphysis ash percentage was significantly increased even after the inclusion of the lowest dose of phytase. Analysis of structural parameters of femur mechanical strength (Young’s modulus, yield stress, yield strain, ultimate stress, ultimate strain) showed that the inclusion of a phytase dose of 500 FTU/kg in growing/finishing diets was sufficient to significantly improve bone status of grower–finisher pigs at slaughter.

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.

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.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

Deficit of conventional feed resources in meeting increased demand has led to hike in their prices culminating in soaring cost of livestock feed. This has necessitated the search for cheap and easily available alternatives. Pride of barbados seed which constitute a waste has potential of becoming a cheap and easily available feed resource. Performance and nutrient digestibility of dietary inclusion of raw pride of barbados seed meal was evaluated in an eight week feeding trial. Atotal of sixteen crossbred (Large White x Landrace) weaned pigs of eight weeks of age were weighed and allotted to four dietary treatments with four pigs each being a replicate in a completely randomized design. Diet 1 (control) was without raw pride of barbados seed meal while 5%, 10% and 15% of virgin raw pride of barbados were included in diets 2,3 and 4 respectively. Weekly weight gain, daily feed intake, feed conversion ratio and nutrient digestibility of raw pride of barbados seed meal was also determined. Results revealed a significant average final body weight of 16.75kg (diet 3) to 24.50kg (diet 4).The pigs fed 15% raw pride of barbados had the highest feed intake of 137.20kg in diet 4 while the lowest feed intake was obtained in pigs fed 10% (diet 3) inclusion level of raw pride of barbados. Pigs maintained on the control diet had the best feed conversion (7.60kg) while the pigs fed diet 3 had the lowest feed conversion ratio (8.93kg). Crude protein, ether extract and dry matter digestibility was highest at T4 (84.15%, 80.21% and 86.70%) respectively while the least values (68.71%, 65.75% and 71.10% was obtained in T2 and T3 respectively. This study concluded that 15% inclusion of raw pride of barbados in the diets of crossbred weaned pigs had no deleterious effect on performance and nutrient digestibility of pigs.

SummaryA total of 432, one-day-old broiler chickens were randomly assigned as a 2 × 4 factorial design (pellet or mash and 0, 25, 50, and 75% whole sorghum levels) in a completely randomised experiment, having six replicates with nine birds per replicate. Body weight and feed intake were measured on a pen basis at 10, 25, and 35 days of age and feed conversion ratio calculated. Pelleting diets significantly improved (P<0.05) feed intake, body weight and carcass yield of broiler chickens at 10 and 24 days of age. Heavier relative gizzard weights with lower pH (P<0.05) were recorded for broiler chickens offered mash diets at 35 days old. Feed conversion ratio at 35 days of age increased (P<0.035, quadratic effect) with higher levels of whole sorghum and levelled off at 75% inclusion rates. Relative gizzard weight at 35 days was marginally increased (P<0.033, linear effect) in line with rising sorghum levels. Similarly, relative bursa and liver weights at 35 days increased (P<0.037, quadratic effect and P<0.033, linear effect, respectively) with sorghum inclusion. The results showed that pelleted diets gave superior performance compared to mash diets. Although higher levels of sorghum inclusion in mash diets enhanced gizzard development, performance parameters of birds at 35 days of age were poorer, with 125 g less body weight and an increase in FCR from 1.51 to 1.62 for the 0% and 75% sorghum levels respectively.

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.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

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.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

Biochemical Indices

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.
