An experiment was conducted for a period of 56 days with 36 healthy New Zealand White (NZW) rabbits aged about one months having weight from 370 to 390g to evaluate the effects of dietary citric acid on growth performance, feed consumption and digestibility of nutrients as well as immune status. The experiment was designed with 6 dietary treatments having 6 rabbits per treatment. Rabbits of control treatment (T1) were given the diet without citric acid (CA) but the dietary treatments T2, T3, T4, T5 and T6 contained 0.5, 1.0, 1.5, 2.0 and 2.5% CA respectively. Green grass was supplied on ad libitum basis. The total body weight gain was Addition of CA at the level of 2% enhanced body weight significantly (P<0.05). (P<0.05)(P<0.05) T 734, 776, 812, 862, 911 and 740g for the rabbits fed 0, 0.5, 1.0, 1.5, 2.0 and 2.5% CA containing diets respectively. Total DM intake also increased with increasing the percentage of CA up to 2% level . Incase of feed conversion ratio, there was no significant difference in addition to different levels of CA. Supplementation of CA improved dry matter, crude protein and ether extract digestibility but incase of crude fiber and nitrogen free extract, there was no significant difference. Non significant difference was also found incase of acidity of feed and feces. The highest lymphocyte (73%) was counted in dietary treatment T6 having 2.5% CA, which was 17% higher than the control diet. From the result of this experiment, it may be concluded that the addition of CA up to 2% level in diet improves performance, digestibility of nutrients and immune status of growing rabbit.

An experiment was conducted with commercial broilers to investigate the effects of feeding citric acid, acetic acid and their combination on their performance and to determine the economic competence of using citric acid and acetic acid in broiler rations. A total number of 108 one day old straight run broiler chicks were distributed to four dietary treatments i.e. 0 % citric or acetic acid (A), 0.5% citric acid (B), 0.5% acetic acid (C) and their combinations 0.5% citric acid and 0.5% acetic acid (D). The birds were reared in cages. Body weight gains, feed conversion ratio (FCR), mortality, dressing yield and carcass characteristics were recorded. The performance showed significant increase in body weight gain (P<0.05) when compared with the control during 0-5 weeks of age on 0.5% citric acid (B). Feed consumption increased (P<0.05) at 2nd and 3rd weeks of age on 0.5% citric acid (B). Feed conversion was found higher (P<0.05) during 0-5 weeks of age in treatment B when compared to those of the other treatments. Carcass characteristics were not affected by dietary treatments. The highest mortality was found in treatment A and treatment C due to excessive hot. It may be concluded that use of 0.5% citric acid in the diet of broilers may have better performance in respect of live weight gain and feed conversion.

Feeding trials were conducted to evaluate the effect of including vomitoxin-contaminated wheat (VCW) containing 6.9 mg vomitoxin per kilogram in the complete diet of gilts during gestation and lactation (3 wk) and in the initial diet of weanling pigs up to approximately 23 kg liveweight. Four groups of four littermate gilts were assigned to four dietary treatments (one littermate per treatment) as follows: (1) control with 69% clean wheat (CW) in the diet with 16% crude protein; (2) 1/3 replacement of the CW with VCW; (3) 2/3 replacement of the CW with VCW; and (4) 100% replacement of the CW with the VCW. During gestation gilts were fed 2.3 kg/day of the diet in two meals, and the same diet ad libitum during lactation. The level of vomitoxin (VT) did not have any detrimental effect on body weight change of the gilt during gestation and after farrowing. Ad libitum feed consumption of the gilts during lactation was not significantly different among treatments. Litter size and weight at birth and at weaning time was not affected by the level of VT intake during gestation. One hundred and four weanling piglets (56 males and 48 females) weighing approximately 7.0 kg each were included in an 8-wk feeding trial. Four dietary treatments, including the control diet (treatment 1), contained 73.2% CW and 22% crude protein, and treatments 2, 3 and 4 in which VCW replaced 1/3, 2/3 and 100% CW, respectively. A significant (P < 0.05) reduction in body weight gain in the 8-wk period was observed only when 100% of the cereal included in the diet was VCW. This effect was due to a significant reduction in feed consumption of the piglets. Thus, feed efficiency was not affected by the level of VT content of the diet.

Conventional feed resources for livestock are increasingly becoming more expensive, due to competition with man; hence nutritionists are searching for cheaper, locally-available alternatives. A total of forty-five (45) mixed sex weaner rabbits, aged 5 – 6 weeks, with average initial weights of between 694.42 and 761.10 g were used to investigate the effect of varying levels of cowpea milling waste (CMW) diets on their growth performance and nutrient digestibility. They were randomly allotted to five dietary treatments with nine rabbits per treatment. The control treatment (T1) contained 0 % CMW while treatments T2, T3, T4 and T5 had 10, 20, 30 and 40 % CMW dietary inclusion levels, respectively. Clean water and feed were offered ad libitum daily to the rabbits, and record of their feed intake and growth performance were taken for 12 weeks. At the end of the 11th week, a nutrient digestibility trial was carried out. Results show that there were no significant (P>0.05) differences in final body weight, body weight gain, total feed intake and mortality among the dietary treatments. Feed conversion ratio (FCR) for diets T4 (6.65) and T5 (6.66) containing 30 and 40 % CMW respectively, were as good as that of the control diet (6.11). Dry matter and crude protein digestibility showed no significant (P>0.05) difference across the treatments. Digestibility of crude fibre (72.64, 80.16, 84.04 and 80.90 % for T2, T3, T4 and T5 respectively), ether extract (95.98, 94.90, 96.04 and 94.38 % for T2, T3, T4 and T5 respectively), nitrogen free extract (94.30, 95.18, 93.58 and 94.90 % for T2, T3, T4 and T5 respectively), as well as total digestible nutrient (83.69, 76.11, 81.67 and 80.02 % for T2, T3, T4 and T5 respectively) of the test diets compared favourably with that of the control diet (72.94, 95.23, 96.04 and 80.47 % for CF, EE, NFE and TDN respectively). Hence, it can be concluded that CMW can be used safely as a protein source and included up to 40 % in weaner rabbit diets with no detrimental effect on their growth performance and nutrient digestibility.

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

The aim of this research was the visual characterization and investigating the effects of Alternaria spp. contaminated wheat grains in the starter stage of broilers nutrition on productive parameters and oxidative stress. The research was divided into two phases. Bunches of wheat in post-harvest period of year 2020 was collected from a various locality in Serbia and Albania. In the first phase, collected samples were visual characterized by Alternaria spp. presence by color measurement methods. Gained results are conferred in the range of the color properties of grain color properties of Alternaria toxins. Wheat grain samples were significantly different (p < 0.05) in terms of all measured color parameters (L*, a*, b*). Classification of field fungi in analyzed wheat grain samples showed that the significant field fungi were Rhizopus spp., followed by Alternaria spp., and Fusarium spp. In the second phase, biological tests with chickens were carried out during the broiler chickens’ dietary starter period in the first 14th days of age. At the beginning of the experiment, a total of 180-day-old Ross 308 strain broilers were equally distributed into three dietary treatments, with four replicates each. Dietary treatments in the experiments were as follows: basal diet without visual contamination of Alternaria spp. with 25% wheat (A1), a basal diet with visual contamination of Alternaria spp. with 25% wheat from Serbia (A2), basal diet with visual contamination of Alternaria spp. with 25% wheat from Albania (A3). The trial with chickens lasted for 14 days. After the first experimental week, wheat infected with Alternaria spp. in treatment A2 and A3 expressed adverse effects. The highest body weight of chickens of 140.40 g was recorded in broilers on control treatment A1 with statistically significant differences (p < 0.05) compared to treatments A2 (137.32 g) and A3 (135.35 g). At the end of the second week of test period, a statistically significant (p < 0.05) difference in body weight of broiler chickens could be noticed. The highest body weight of 352.68 g was recorded in control treatment A1, with statistically significant differences compared to other Alternaria spp. treatments. The lowest body weight of chickens was recorded in treatment A3 (335.93 g). Results of feed consumption and feed conversion ratio showed some numerical differences between treatments but without any statistically significant differences (p > 0.05). Alternaria spp. contaminated diet increased glutathione (GSH), glutathione reductase (GR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and decreased peroxidase (POD) and superoxide dismutase (SOD) serum levels, respectively. Built on the achieved results, it can be concluded that the wheat contaminated with Alternaria spp. in broilers nutrition negatively affected growth, decreased oxidative protection and interrupted chicken welfare in the first period of life.

Present study was conducted to evaluate the different levels of energy to protein ratios (EPR) using food waste and black soldier fly larvae meal (FWBSFL) on growth performance and nutrient digestibility of broilers. A total of 160 one-day old broiler chicks were divided randomly to four groups and each group had 8 replicates with 5 chicks per replicate. The control diet was formulated using conventional feed ingredients with EPR of 154 for the starter period and 167 for the finisher period. The other treatments were diets with normal, low, and high EPR (154,143, and 166 for the starter period; 167, 155, and 177 for the finisher period) using FWBSFL. Feed consumption and body weight gain as well as digestibility of crude protein, crude fiber, and fat were decreased due to feeding of FWBSFL diets. Different levels of EPR using FWBSFL decreased growth performance and nutrient digestibility of broilers.

Penggunaan asam sitrat sintetis nyata dapat menurunkan konversi pakan minggu ke tiga dan empat dibanding kontrol dan asam organik belimbing wuluh. Kesimpulan penelitian ini yaitu penggunaan sari belimbing wuluh sebagai acidifier belum menunjukkan perbaikan performa yang signifikan sedangkan penggunaan asam sitrat sintetis memiliki performa yang lebih baik dibanding perlakuan kontrol dan penggunaan sari belimbing wuluh.Kata kunci: acidifier, asam sitrat, belimbing wuluh, puyuh fase growerABSTRACTThe organic and synthetic acidifiers could improve the optimization of nutrients utilization in the quail digestive tract. Furthermore, the optimization of nutrients is expected to improve quail performance. This study was aimed to determine the effect of using two types of acidifiers (Averrhoa bilimbi juice and synthetic citric acid) on the grower phase of quail performance. Total of 100 unsexed quails (Coturnix coturnix japonica) grower phase aged 14-40 days were used in this research and designed as a completely randomized design of five treatments and four replications. Feed ingredients used were yellow corn, rice bran, commercial quail concentrate, Averrhoa bilimbi juice (organic acidifier), and synthetic citric acid. The treatments consisted of control (P0), 0.3% synthetic citric acid (P1), use of 0.25% Averrhoa bilimbi juice (P2), use of 0.6% synthetic citric acid (P3), and use of 0.5% Averrhoa bilimbi juice (P4). The variables observed were weekly feed intake, body weight gain, and feed conversion. The result showed that utilization of Averrhoa bilimbi juice has lower feed consumption (P<0.05) in the first week compare to control and synthetic citric acid, and synthetic citric acid utilization increases body weight gain in the first week (P<0.05). The use of synthetic citric acid significantly reduces feed conversion in the third and fourth weeks compared to control and organic acid groups. The conclusion of this study is the utilization of Averrhoa bilimbi juice as an acidifier has not shown significant improvements in quail performance. The use of synthetic citric acid has a better performance compared to control and Averrhoa bilimbi juice utilization.Keywords: acidifier, organic acidifier, citric acid, growing quail

ABSTRACT. Tempe of soybean is fermented soybean with Rhizopus ologosporus fungus. From a result of researchers, it is the fact that tempe can increase valuable of nutrion and digest capacity and also produce antibiotic . Utilization of abtibiotic in chiken food as stimulus growth in not recommended because it can cause resistance a certain germ and it is presume there are antibiotic residu in egg and chiken meat. It is hope that the use of fermented soybean oil meal can increase nutrient value and digest capacity as well as produce antibiotic, so that it can get a better growth and over come a problem of using antibiotic in chiken food. The study was conducted to evaluate the effect of fermented soybean oil meal utilization in the ration on body weight gain, feed consumption, feed conversion and mortality. The study use 80 unsex day old chick broiler CP-707 and conducted at Poulty Laboratory Product Agriculture Faculty, Syiah Kuala University. Chiken were putting in 27 houses unit, each unit contain of four chiken. The design of experiment was Completely Randomized Design, four treatments and five replication. The treatments were ration contained 0%, 5%, 10% and 15% fermented soybean oil meal as replace the use of soybean oil meal. The protein and energy content of all dietary treatments were equally composed from six weeks investigation, were body weight gain, feed consumption, feed conversion and mortality. The result of the study indicated that up to 10% graded of fermented soybean oil meal in ration were significant difference influenced increase the body weight gain and decrease the feed conversion. The fermented soybeanoil meal) utilization more than 10% were significant difference decrease the body weight gain and increase the feed conversion. If the inclusion was increase the feed consumption would tendency decline. In this study there were no mortality in all treatment.

The effect of different levels of supplemented dietary protein on body weight, certain haematological values and meat yield characteristics in 20 "Shaver Star Bro" broilers was studied during the period from 02 March to 12 April 2002. The broilers were randomly assigned to four equal groups (A to D) each consisting of 5 birds. Group A was considered as control, fed only with commercial ration and other three groups were treated with extra dietary protein supplement @ 5%, 10% and 15% as group B, C and D respectively. Increased body weight was recorded in group B and the body weight decreases as the level of protein increased from 5% to 10% and 15% and the decrease was linear. No differences in haematological values were observed among the groups but the TEC varied significantly (p < 0.05). The mean weight of breast meat, drum stick meat varied significantly (p < 0.01). The shank weight varied significantly (p < 0.05) but there was no significant difference among the mean weight of thigh meat and wing meat corresponding to the different levels of supplemented dietary protein. It can be concluded that 5% supplemented dietary protein with commercial ration gives better result in respect to body weight gain, haematological values and meat yield characteristics.Key words: dietary protein; haematological values; meat yield; broiler birdsdoi: 10.3329/bjvm.v2i2.2543Bangl.
