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 < 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 < 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 < 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 this study was to develop the least-cost starter’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’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<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<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’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<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’s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

Leaf Meal

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.

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 study was conducted to evaluate the effect of feed restricted (off-feeding intervals) on feed intake, water intake, body weight gain, growth rate, feed conversion ratio, mortality, and dressing percentage of broilers. Two hundred fourty, one day old unsexed, (Ross 308) broiler chicks were randomly distributed into four treatment groups. Each group included three replicates each one had 20 birds. Those assigned as; Control group (T1): birds were fed ad libtium, T2 group feed removed from 8 Am. to 4 Pm., T3 group feed removed from 4 Pm. to 8 Am., T4 group feed removed 8 Am. to 8Am. (skip-a day) all birds were allowed to access feed for above intervals for 8-21 days of age, and re-full fed for the remaining of experiment period 42 days. The results indicated that feed restriction system did significantly (P<0.05) affect live body weight, body weight gain, and feed conversion ratio on starter diet period. Feed restriction significantly P<0.05 reduced feed consumption accompanied with water consumption positively correlated, decreases mortality in restriction period and at marketing, and increase dressing percentage, improved characteristics of carcasses at marketing age, the compensatory growth may be appeared after re-full free feeding for restricted groups to reach a close the market weight as control group., that was indicated by an increase in growth rate post feed restriction period especially at week (6th) as compared with the control group

Abstract The aim of this study was to evaluate possibility for valorization of the dry pressed distilled rose petals (DDRP) as a feedstuff phytonutrients in animal husbandry. In connection with the chemical composition and radical scavenging activity of polyphenol complex in rose waste products were studied. The polyphenol composition in dry rose petals, DDRP and waste water after distillation was identified and quantified. The chromatographic analysis was conducted by HPLC-PDA and LC-MS. The experiments were conducted with bird, monogastric and ruminants representatives. A total of 40 one days old chicks from the hybrid combination Ross 308 were distributed into two groups each containing of 20 birds fed for 49 days. The control group C fed with basal diet vs. experimental group R fed with the same fodder plus 40 mg DDRP/kg/d. A total of 72 Danube White 155 days old fattening pigs (both sexes - 36 male and 36 female) of 72.500 ± 1.937 kg were distributed into three groups (one control C and two experimental R1 and R2 supplemented with 0.255 g DDRP/kg/d or 0.545 g DDRP/kg/d). Each one group (24 piglets) was fed for 45 days. A total of 30 numbers of 65 days old lambs from the Synthetic population of Bulgarian milk sheep breed lambs (both sexes - 15 male and 15 female) with average life weight 20.500 ± 1.039 kg were divided into two groups (control C and experimental R) each one containing of 10 animals fed for 50 days. The experimental group was fed with combined feed for lambs granules and ground alfalfa supplemented either 0.545 g DDRP/kg/d. Animals were assessed for average daily weight gain and feed conversion ratio. Thirteen glycosides of kaempferol, ten glycosides of quercetin, six glycosides of gallic acid and the two flavonol aglycones have been identified in dry rose petals. Those polyphenols possess high antioxidant activity and positively influence the growth performance of pigs. The supplementation of pig's feed with 545 mg DDRP/kg/d increased (p < 0.05) with 6.73% the total feed consumption and with 27.05% the average daily weight gain, and decreases with approximately 16% the feed conversion ratio comparing to control group (C) pigs fattening without DDRP supplementation. The studied concentrations of DDRP were not effective in small ruminants and poultry husbandry.

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.

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.

Breed effects on live weight gain, slaughter characteristics and carcass composition were compared in Aberdeen Angus, Charolais, Hereford and Simmental bulls. The experiment extended over 2 years and involved totally 96 animals. The target slaughter live weights were determined 550 kg for earlier maturing breeds Aberdeen Angus and Hereford and 630 kg for later maturing breeds Charolais and Simmental. Charolais and Simmental gained more rapidly (P &lt; 0.05) than Aberdeen Angus while Hereford were intermediate. Hereford had lower (P &lt; 0.05) dressing percentage than the other breeds. Percentages of grade I meat were significantly higher (P &lt; 0.05) in Charolais and Simmental. The highest percentage of separable fat was recorded in Hereford (P &lt; 0.05). Charolais and Simmental had lower (P &lt; 0.05) thickness of subcutaneous fat over MLLT than Aberdeen Angus andHereford. The later maturing bulls generally tended to achieve higher live weight gains during the experiment, produced less fat and had higher percentage of meat from high priced joints in comparison with earlier maturing animals. &nbsp;
