The present study examined the efficiency of thyme in improving the productive and reproductive performances in male rabbits living in hot climates with the further lowering of the faecal ammonia and adverse heat stress. One hundred and twenty-five Zealand-White male rabbits were assigned to five dietary treatments [age: 60-day-old; body weight (b.w.): 1 362 ± 20 g] (n = 25). The basal diet was supplemented with either 0 (control), 4, 8, 12 or 16 g/kg of thyme leaves. The experiment lasted for 90 days. The feed and water were provided ad libitum. The animals were housed in an open system (39 °C ambient-temperature and 30–35% relative-humidity). The dietary thyme leaf levels significantly improved the appetite, body weight gain and growth performance compared to the control (P < 0.001). The weight gain and feed conversion ratio were directly proportional to the thyme leaves intake. The faecal ammonia was markedly lowered in response to the feeding with thyme leaves. The thyme leaves significantly improved the liver and kidney functions as indicated by their biomarkers. The testosterone concentrations and semen characteristics were also significantly improved in the thyme leaves-treated groups compared to the control (P < 0.01). In conclusion, thyme leaves, at an optimum dose of 16 g/kg of the diet, could be an efficient feed additive for rabbits surviving under hot climatic conditions.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

An experiment was conducted with 312 day-old male broiler chicks in grower phase(8-28d) to estimate the biological availability of four sources Zinc (Zn), Zinc sulfate(ZnSO4.H2O), two sources of Zinc oxide(ZnO FG1 and ZnO FG2) and Bioplex Zn. Zinc sulfate (ZnSO4.H2O) was used as the standard in the bioavailability assay. Chicks were allotted randomly to 13 dietary treatments with 6 birds per replicate and 4 replicates per treatment, that included an unsupplemented corn-soybean meal basal diet (25.50 mg of Zn/kg of DM), or the basal diet supplemented with 100, 150 or 200 mg/kg of DM as either ZnSO4.H2O (33 % Zn), Zinc oxide FG1(72%Zn), Zinc oxide FG2 (75%Zn) or Bioplex Zn (15% Zn). Dietary Zn level and source had no effect (P>0.05) of feed intake or body weight gain of chicks during first and second weeks of experimental periods, but feed conversion ratio in the first and second week and feed intake, body weight gain or feed conversion ratio in third week and total experimental periods were significant difference between treatments (P<0.05). The relative biological availability values using body weight gain were estimated to be 59, 99 or 45 for three levels of Zinc oxide FG1, 64, 78 or 31 for three levels of Zinc oxide FG2 and 151, 200 or 147 for three levels of Bioplex Zn, respectively. From the standpoint of bioavailability, Bioplex Zn was more available to broiler chicks than Zn from other sources and can be used by the feed industry as sources of supplemental Zn for broiler chickens.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

The use of conventional supplements as feed additives has been criticized for their potential negative impact on the food chain hence, the need for viable organic alternatives. Centella asiatica has been found to contain essential phytochemicals. This study was therefore carried out to evaluate the utilization of dried Centella asiatica leaf meal (CALM) as phytogenic feed additive in broiler chicken diet. A total of 180, one-day-old Arbor acre broiler chicks were randomly allocated to six dietary treatment groups with thirty birds, at three replicates of ten chicks per replicate. Experimental diets included control basal diet + 0% CALM (T1), basal diet + antibiotics (T2). T3, T4, T5 and T6 were basal diet + 3%, 4%, 5% and 6% CALM respectively. Experiment was designed using completely randomized design. Feeding trial was carried out for 49 days. Parameters measured included growth nperformance and carcass characteristics. All data were subjected to analysis of variance using Statistical Package for Social Sciences (version 21) while treatments means were nseparated using Duncan's multiple range test at P≥0.05 level of significance. There wer significant differences in final live weight, body weight gain and feed conversion ratio. Birds fed with 4% CALM had the highest weight gain (1,683.30g) and feed intakes (3,295.30g), while T3 had the lowest weight gain (1,446.70.30g) and feed intake (3,107.80g). The breast cut showed significant (P<0.05) variation across the treatment with treatment T2 having the largest value of 31.9% and lowest value of 26.0% was in T3, thigh showed highest value in T5 and lowest value in T4. Gizzard values obtained in this finding showed significant (P<0.05) value ranged from 1.8-2.6% the highest value was obtained in T3 and lowest value in control diet. It can be concluded that the inclusion of Centella asiatica in the diets of broiler chicken has no detrimental effect on the performance characteristics of the experimental birds but improved the average body weight, feed conversion ratio and livability of the birds at 4% level of inclusion.

This study was conducted to evaluate the effect of garlic an alternative feed additive in broiler diet.  The experiment was carried out for a period of 32 days with a number of 340 day-old straight run broiler chicks. Birds were divided into five dietary treatment groups with 4 replications each having 17 birds. The dietary groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), garlic 0.25% (basal diet + 0.25% garlic powder), garlic 0.50% (basal diet + 0.50% garlic powder) and garlic 0.75% (basal diet + 0.75% garlic powder). Results showed that the body weight, body weight gain and total FCR were not differ significantly (P>0.05) among the treatment groups. Total feed intake in different dietary levels showed significant (P<0.05) difference. Control group showed significantly (P<0.05) higher feed intake than the other dietary groups. The results also showed thatthe serum glucose concentration was reduced (P<0.05) in all garlic supplemented groups compared to the control and antibiotic groups. Total cholesterol level was significantly (P<0.05) lower in the 0.75% garlic group compared to the control and antibiotic groups. In case of dressing parameter, 0.75% garlic group showed lowest (P<0.05) abdominal fat compared to the other groups. Cost of production per kg live broiler was lower in antibiotic and control groups compared to the garlic group. With regards to profit, antibiotic groups showed higher profitability than the other groups. It can be concluded that the addition of garlic powder to broiler diet had positive effect on cholesterol and glucose levels and had no effect on feed intake, body weight gain, meat yield, bone development, carcass parameters. It can be suggested that the garlic could be a potential feed additive in broiler diet.Bang. J. Anim. Sci. 2017. 46 (4): 215-224

A total of 180 day old broiler chicks (Cobb 500) were allocated randomly to five treatment groups with 3 replicate having 12 birds in each reared for a period of 28 days. The aim of this study was to find out whether koroch seed cake (KSC) had any effect upon broiler at different age group. Therefore, two diets were formulated: 1) basal diet with 0% KSC and 2) basal diet with 2% KSC. The birds of different treatment groups received either diet i or ii in the following way: Control group (T1)=0% KSC throughout the experimental period, T2 =1st 21days 0% KSC diet + rest 7 days 2% KSC diet, T3=1st 14days 0% KSC diet + rest 14 days 2% KSC diet, T4=1st 7 days 0% KSC diet + rest 21 days 2% KSC diet, and T5=2% KSC throughout the experimental period. Body weight, body weight gain, feed consumption and mortality of broilers were recorded weekly and also whole experimental period. Feed conversion ratio (FCR) was also calculated. Weekly body weight and body weight gain did not show significant differences during 1st, 2nd and 4th week of age, while significant differences were found in 3rd week of age. In 3rd week, the body weight and body weight gain was the lowest in T5 (fed 2% KSC diet) among the Treatments. The final body weight was 906.69, 864.05, 869.92, 860.87 and 838.89 g for T1, T2, T3, T4 and T5, respectively and found non-significant result. Similar pattern of result found in body weight gain of the birds. Feed intake and feed conversion ratio of birds at different weeks and during whole experimental period did not differ significantly (p>0.05). All the meat yield parameters showed a non-significant effect of age of broilers fed with 2% KSC.  Results of this experiment revealed that the feeding of 2% KSC at different ages fail to show any significant effect on broiler performance.Bang.

Probiotics is a feed additive in the form of life microorganisms that balance microorganism population in the digestive tract. This research was conducted to study the effect of addition of probiotics product into drinking water on performance. One hundred and fifty birds of day old chicks (DOC) of “Hybro-AM”strain were divided into 5 groups of treatments. The treatments were R0 (control diet+ drinking water without probiotics), R1 (R0 + Temban), R2 (R0 + Biolacta), R3 (R0 + Biovet), and R4 (commercial diet). Chicken were given diet and drinkingwater ad libitum. Feed intake, body weight gain and feed conversion were measured weekly and income over feed and cost (IOFC). Local feed (control died) and control with probiotics are feed with self formulation (R0, and R1 – R3). Thecontrol feed ingredient used are corn, rice brand, fish meal, hull soybean mea, palm oil, grit,DCP and premix. Results showed that treatments did not give significant effect (P>0,05) on feed intake, body weight gain and feed conversion. The result of Income Over Feed Cost (IOFC), shows that feed with control diet with probiotics Temban are best alternatif to pressure high price of feed and useable by farmer.
