A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 18 weeks old, nine castrated DYL and nine local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 0.95% total lysine for finisher and L3- basal diet with 1.45% total lysine for finisher. The growth performance and back fat thickness were determined for finishing pigs. Significantly better body weight, weight gain, feed conversion ratio (FCR) and lower back fat were observed in pigs fed L2 but did not significantly differ from those fed L3. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and feed efficiency. Between the two breeds, growth performances of DYL were superior over that of local breed. Back fat thicknesses of DYL were also thinner than that of local breed. The interactions were observed between lysine levels and different breeds regard for final body weight, cumulative gain and feed conversion ratio. It was noticeable that lysine supplementation helped to improve growth performance and reduce back fat thickness of both local breed and DYL crossed breed. The result also showed that a comparison of the two different breed revealed the improved performances in DYL crossed breed rather than that of local breed.

Commercial Diet

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.

The aim of the present study was to evaluate the effects of feed particle size and flooring designs on organ traits, performance and pododermatitis in broilers. A total of 480 broilers (Ross 308) of both sexes were randomly assigned to two feeding groups (finely or coarsely ground pelleted diets; with addition of 5% to 10% intact wheat in coarsely diets) and four different housing systems (litter; litter with floor heating; partially or fully slatted floor) with three subgroups each. A coarse diet increased the final gizzard and pancreas weights (p < 0.001) while decreasing the risk of Isthmus gastrici dilatation compared to a fine diet (p < 0.001). Broilers fed a coarse diet displayed an increased final body weight (p = 0.023) and led to a favourable feed conversion ratio. Final body weight was the highest (p < 0.001) for birds housed on partially or fully slatted floor. Housing birds on litter with floor heating showed the lowest pododermatitis scoring (p < 0.001). It seems to be favourable to use coarse diets for organ development, whereas slatted floors seem to foster enlargement of the Isthmus gastrici. Increasing growth performance was possible both when using coarse diets or slatted floors.

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.

Abstract The purpose of this study was to evaluate the growth performance of Peking ducks fed with rations containing waste products of leubiem fish (Chanthidermis maculatus) and probiotic agents. The study was conducted experimentally using 96 Peking ducks, within an age range of about 1 to 8 weeks, and a Completely Randomized Design (CRD), which consisted of four treatment rations and four replications. The treatment rations used in this research included treatment R0, which was the basal diet, serving as the control ration, and also treatment R1, R2, and R3, which consisted of 10% concentration of leubiem fish skin, head, and bone, respectively, as well as 1% of a probiotic agent. The observed variables included the rate of feed consumption, body weight gain, final body weight, feed conversion ratio, and mortality were then analysed using Analysis of Variance (ANOVA). The results showed that the use of leubiem fish components and probiotic agents in rations at 10% and 1%, respectively, had a significant effect (p<0.05) on the rate of feed consumption, body weight gain, feed conversion ratio and final body weight. However, there was no significant effect on the mortality of Peking ducks. Therefore, this study concluded that the use of rations containing leubiem fishbone and probiotic agents at 10% and 1%, respectively, were able to accelerate the growth performance of Peking ducks.

Dietary Treatments

An experiment was conducted to evaluate the efficacy of AZOMITE® as source of natural minerals on growth performance of commercial broiler. A total of 1,020 day-old Cobb 500 male broiler chicks were randomly allocated to 5 dietary treatments with 6 replications per treatment having 34 chicks in each pen. The five dietary treatments were: (i) basal diet without AZOMITE®, (ii) basal diet with 0.25% AZOMITE®, (iii) basal diet with 0.50% AZOMITE® which was recommended by manufacturer, (iv) basal diet with 0.75% AZOMITE® and (v) basal diet with 1.0% AZOMITE®. Broilers were reared in open-sided gable type house for a period of 32 days. Results showed that the supplementation of AZOMITE® had significant effect on growth performance (p<0.01) of broilers. Live body weight (LBW), body weight gain (BWG), average daily gain (ADG), feed intake (FI), feed conversion ratio (FCR), European efficiency factor (EEF) and gain cost of the birds fed various levels of AZOMITE® were significantly improved as compared to the control. Meat characteristics results indicated that the treatments had no significant effect on dressing percent, thigh, drumsticks and breast percentage among the dietary groups. Taken together, it may be concluded that the supplementation of AZOMITE® in commercial broiler at 0.50 to 1.0% improved live weight, feed intake and feed conversion ratio of commercial broilers.

Background The benefits of probiotics being used in animals are well-documented via evidenced growth performance improvement and positive modulations of gut microbiota (GM). Thus, a combination of effective microorganisms (EM) has been frequently used in animal production, including broilers. However, there are only very limited reports of EM on the growth performance and the modulation in GM of partridge shank broiler chicks. Methods We attempted to evaluate the effects of a basal diet with the addition of an EM mixture on the growth performance and gut microbiome of the chicks. A total of 100 ten-day-old female partridge shank broiler chicks were randomly divided into two groups of 50 chicks each, of which, one group fed with EM supplementation in the basal diet (designated as EM-treated group), the other group just fed with a basal diet (referred as to non-EM treated group or control group). The body weight, daily feed intake, daily gain, feed conversion ratio and other growth parameters were observed and compared between EM-treated and non-EM-treated chicks, and the gut microbiota was profiled by 16S rRNA-based next generation sequencing (NGS). Results EM-treated chicks showed significantly increased performances in body weight (BW), average daily gain (ADG) and reduced feed conversion ratio (FCR). Histological observation indicated that dietary supplementation of EM significantly increased the villus heights (VH) and the ratio of villus height to crypt depth (VH/CD), while decreased the CD of jejunum, ilea, and ceca. The results of 16S rRNA-based gut microbiota analyses showed that Firmicutes accounted for the most of the relative abundance (63.24%∼92.63%), followed by Proteobacteria (0.62%∼23.94%), Bacteroidetes (0.80%∼7.85%), Actinobacteria (0.06%∼13.69%) and others in both EM-treated and non-EM-treated broiler chicks. The addition of EM could not alter the alpha diversity of gut microbiota. Compared with the non-EM-treated chicks, the abundances of bad bacteria in the phyla of Firmicutes, Euryarchaeota, and Ruminococcus were dramatically decreased in that of EM-treated chicks, while the abundances of good bacteria in the phyla of Actinobacteria and WPS-2 were significantly increased. Conclusions The supplementation of EM in feed could improve the growth performance and positively influence the morphological characteristics of the intestine, and ameliorate the community and structure of the intestinal microbiota of partridge shank broiler chicks.

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.

Abstract                         A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 12 weeks old, nine castrated DYL and nine castrated local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 1.15% total lysine for grower and L3- basal diet with 1.65% total lysine for grower. The growth performance and feed intake were determined for growing pigs. In this study, no significant difference (p>0.05) was found in feed intake among the three different treatments. However, significantly better body weight, weight gain and feed conversion ratio (FCR) were observed in pigs fed L2 and L3 but were not significantly (p>0.05) differ from each other. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and farm efficiency. Between the two breeds, body weight of DYL was superior over that of local breed. The interactions were observed between lysine levels and different breeds regard for body weight and cumulative weight gain. To wrap up, it was noticeable that crystalline lysine supplementation helped to improve growth performance in both breeds.

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.
