SummaryThis study evaluated the effect of an enzyme blend (xylanase, amylase and protease; XAP) in combination with a direct fed microbial (DFM) containing three strains of Bacillus spp. on intestinal histology, immune response and performance of broilers. Four dietary treatments were tested in a 2 × 2 factorial trial, including two levels of challenge (without or with coccidial infection), two levels of feed additive (with or without XAP and DFM). Diets were fed ad libitum to male Cobb500 broilers in mash feeds from 1–21 days of age, with eight replicate pens per treatment within brooder-batteries with raised wire floors and built up litter, housing six birds per pen. A mild challenge was introduced by oral gavage at day five to the challenged birds, using a six-fold concentration of coccidial vaccine. A high fibre basal diet formulated with rye and wheat middlings was used to further increase the challenge. Body weight and feed intake were measured and feed conversion ratio (FCR) was calculated during starter (1–12 d), grower (12–21 d) and overall 1–21 days. Intestinal morphology and immune response parameters were measured on day 12 and 21. Compared to the unchallenged groups, the coccidial challenge reduced (P < 0.05) body weight gain (BWG), increased FCR, reduced villus height and increased crypt depth. The challenged birds had increased pro-inflammatory cytokines (IL-6, IL-1β; P < 0.05) in the intestine as well as higher levels of acute phase proteins (APP, haemopexin and α−1-acid glycoprotein) in the plasma and circulating heterophils. XAP + DFM supplementation improved BWG, reduced FCR and increased energy efficiency compared to the non-supplemented groups. The combination of XAP and DFM reduced inflammatory responses such as APP compared to the challenged control group and maintained performance to a comparable level seen in the unchallenged control. The data indicate that XAP enzymes in combination with Bacillus-based DFM may reduce the damage and performance losses induced by coccidial challenge.

The study included 300 unsexed broiler chicks (Hubbard) were used to evaluate (Roselle Flower) as a feed additives on the productive performance of broiler. The chicks were divided into five groups with three replicates (20 birds in each) and fed on five diets. Diet 1 (control group) dried Roselle flower powder were supplemented to the diet 2, 3, 4 and 5 as 0.25, 0.5, 0.75 and 1% respectively. The result revealed that a significant (P<0.05) increase in body weight, body weight gain, feed consumption and improvement in feed conversion ratio. Although the differences between groups for edible parts percent were not significant (Heart, Liver and Gizzard). The hematological values PCV%, RBC, WBC and H/L ratio were increased significantly (P<0.05) and cholesterol values decreased significantly as compared with control group. It can conclude that Roselle as other herbal plants may be considered as a feed additive in broiler diet would improve the productive performance, hematological and biochemical values of broiler. Diet Roselle flower supplementation of (1g/kg) might be acceptable for achieving optimum broilers performance.

This study was to evaluate the effect of chamomile alcoholic extract on performance, some blood parameters and intestinal characteristics of broiler chicks. A total 320 one day old Cobb 500 broiler chicks were randomly divided into 4 treatments. Treatments were further divided into 4 replicates. Chicks were fed a basal diet as control group, basal diet with 0.3% chamomile extract (S1), basal diet with 0. 5% chamomile extracts (S2) and basal diet with 0.7% chamomile extract (S3). The experiment was carried out of 42 days. Feed intake FI and body weight gain BW was calculated for estimation of feed conversion ratio FCR. At the end of experimental period (42 days), to determine carcass traits and other parameters, 2 birds form each replicates were slaughtered. Additionally, the blood serum samples were subjected to biochemical analysis. For determination intestinal characteristics, small intestine tissues were collected. Data from this study showed that improvement of body weight gain and feed conversion were found in chamomile extract groups (P<0.05). There were significant differences between carcasses traits in treatments feed by chamomile extract. As result reveled from this study serum triglyceride, cholesterol LDL decreased in groups fed by chamomile alcoholic extract and HDL increased significantly (p<0.05) instead. In addition villus height decreased in S1and S2 groups. An increasing crypt depth was seen on S2. According to these data villus widths, epithelium layer and goblet cells increased by using chamomile extract specially by using S2. In conclusion we could demonstrate that chamomile alcoholic extract may be used as ingredient in broilers ration without harming effects on carcass characteristics, blood biochemical parameters, and intestinal morphology of Ross 308 broiler chicks.

The aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,99±0,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%.  (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.99±0.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.

Among the most important issues of food safety, which conducted an extensive international discussion, is the use in livestock of drugs, such as recombinant bovine growth hormone, or somatotropin, and, in particular, ractopamine, stimulating the growth of cattle, pigs and poultry. Ractopamine is used in veterinary medicine to increase the meatiness of the carcass. Ractopamine improves feed conversion, reduces body fat through lipolysis and an intense muscle-building. In the United States, Australia, Argentina, Brazil, Canada and many other countries, ractopamine is allowed for usage as growth stimulator in livestock. However, in most countries of the European Union the use of ractopamine is forbidden. In this regard, it seems very important to develop effective and safe drugs that can stimulate the production of endogenous somatotropic hormone (STH). We propose to use for this purpose Gamavit – well-studied veterinary medicine stimulating metabolism and widely used by veterinary specialists in the Russian Federation, Ukraine, Belarus and some other countries. The aim of this work was to study the effect of Gamavit on STH production in suckling piglets and lambs. Previously it was shown elsewhere that Gamavit induced 2-fold increase in the STH blood level in calves. The experiment was done using 30 suckling piglets of Landrace breed at the age of 0 to 7 days and 10 newborn lambs of the Stavropol breed. All animals were kept in identical conditions, they were fed the same balanced diet. The study was conducted according to the following protocol: The piglets of the 1st group (control) received 0.9% NaCl solution at a dose of 0.5 ml/kg intramuscularly on the 1st, 2nd, 3rd and 5th days of the experiment. Piglets of group 2 (experimental) were inoculated with Gamavit at a dose of 0.5 ml/kg intramuscularly on the 1st, 2nd, 3rd and 5th days of the experiment. Lambs were inoculated with Gamavit at a dose of 0.5 ml/kg of body weight on 7th, 14th and 21st days after birth. Using method of enzyme immunoassay we shown that during the study level of STH in the experimental group of piglets inoculated with Gamavit gradually increased from 8.5 mIU/l before the experiment to 14.3 mIU/l on the 5th day. In the control group it ranged from 7.5 mIU/l to 10.2 mIU\l. At the end of the experiment greatest body weight gain was observed in the experimental group and amounted 45.450 g compared with 26,700 g in the control group piglets. In the experimental group of newborn lambs Gamavit induced raise in the STH serum level 2 from 6.5 mIU/l at day 0 to 13.1 mIU/l at day 21. Thus, Gamavit, unlike synthetic growth hormone, ractopamine and other beta-agonists used in livestock, induces the production of endogenous STH, which stimulates growth of the animal, while being safe and rapidly metabolizing on its own metabolic pathway.

Functional additives, such as autolyzed yeasts, have been used to achieve greater production efficiency and animal health. These compounds are also alternatives to the use of performance-enhancing antimicrobials. The objective was to evaluate the productive performance, ingestive behavior, apparent digestibility of feed DM and the carcass characteristics of beef steers finished in feedlot receiving autolyzed yeasts in the diet. The experimental design was randomized blocks, consisting of three treatments and six repetitions, where each repetition was represented by a stall with two animals. 36 bulls, ½ Angus × ½ Nelore blood, from the same herd, with an average age of 11 months and an average body weight of ± 330 kg were used.The treatments were as follows: CON - yeast-free diet; Y4 - yeast diet (4 g animal day-1) and Y7 - yeast diet (7 g animal day-1). The product used is a functional ingredient containing the yeast Saccharomyces cerevisiae. The inclusion of autolyzed yeasts resulted in greater daily body weight gain and better feed conversion in the initial feedlot phase. The apparent digestibility of DM of diets containing autolyzed yeast was superior to the control diet, and its use did not interfere with the animal ingestive behavior. Supplementation with autolyzed yeasts at the inclusion level of 4 g day-1 promoted better results in the finishing of feedlot steers, and that the supplemented groups (4 g animal day-1 and 7 g animal day-1) achieved the same degree of carcass finishing, higher than the control group.

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.

This study is targeted at evaluating whether C. deserticola addition promotes digestion, nitrogen and energy use, and methane production of sheep fed on fresh forage from alfalfa/tall fescue pastures. The sheep feeding trial was conducted with four addition levels with C. deserticola powder, and a basal diet of fresh alfalfa (Medicago sativa) and tall fescue (Festuca arundinacea). Addition levels of 4% and 6% improved average body weight gain (BWG) by 215.71 and 142.86 g/d, and feed conversion ratio (FCR) by 0.20 and 0.14, respectively. Digestibility of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and ether extract (EE) was 62.25%, 65.18%, 58.75%, and 47.25% under the addition level of 2%, which is greater than that in the control group. C. deserticola addition improved energy utilization efficiency, while addition levels of 2% and 4% increased nitrogen intake and deposited nitrogen. Overall, C. deserticola has the potential to improve growth performance, digestion of sheep, so it has suitability to be used as a feed additive.

A trial was conducted with 32 indigenous goat kids (Capra prisca) 8,5 weeks old to examine the effectiveness of dietary avoparcin as growth promoting factor. The kids were randomly allocated into two groups (control- and avoparcin group with initial mean body weight of 11,61 ±1,16 kg and 11,57±1,47 kg, respectively) comprising of 16 kids (8 male and 8 female) each. For a period of 12 weeks, kids in the control group were given lucerne (alfalfa) hay (mean daily consumption 170 g/head) and an appropriate compound diet (given ad libitum), while kids in the avoparcin group were fed the same diet except that the compound diet was supplemented with avoparcin (20 mg/kg). Avoparcin supplementation significantly (P<0.05) improved final mean body weight by 10.57% (19.24 ± 2.33 kg vs. 17.40 ± 2.30 kg), body weight gain (BWG) by 32.30% (7.66 ± 1.42 kg vs. 5.79 ± 1.74 kg), mean daily feed consumption in dry matter basis (DM) by 14.24% (551.80 ± 31.60 g DM vs. 483.02 ± 28.94 g DM), feed conversion ratio by 13.62% (6.09 ± 0.47 kg DM consumption/kg BWG vs. 7.05 ± 0.56 kg DM consumption/kg BWG) and carcass weight by 14.86% (11.44 ± 1.48 kg vs. 9.96 ± 1.76 kg). Moreover, no significant differences (P>0.05) were noticed neither in carcass yield and carcass chemical composition nor in percentages of small intestine-, major omentum-, lung-,heart-, liver- and spleen weight in the body weight.

This study was conducted to determine the effect of phytogenic feed additive and prebiotic on vegetable protein base diet in broiler performance.  A total of 90 chicks (Cobb-500) were weighted and randomly assigned to the three treatment groups (To, T1 and T2) and supplemented with either phytogenic feed additives or prebiotic and reared for 28 days. Data on live body weight, body weight gain, feed intake and feed conversion (FC) were taken at weekly interval. Results revealed that significant (P<0.05) increase in live body weight of broilers was evident in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group at 4th weeks of age. No significant (P>0.05) differences were found in live weight gain among the treatment groups on weekly intervals along the whole experimental period. However, significant differences (P<0.05) were evident on cumulative weight gain at 3rd and 4th weeks of age. In case of feed intake at the age of 3rd and 4th weeks, significant (P<0.05) differences were obtained with decreased feed intake in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group. In case of feed conversion (FC), there were significant (P<0.05) differences among the groups on 1st week and 4th week of age. Best FC was accounted for prebiotic supplemented group along the whole experimental period. The survivability rates were 96.67%, 100% and 100% in control group, phytogenic feed additive and prebiotic supplemented group respectively. Results finally showed that vegetable protein when supplemented with phytogenic prebiotic feed additives and prebiotic c an additive beneficial effect on performance of when compared to non-supplemented control diet. So, ration using vegetable protein mixed with phytogenic feed additives or prebiotic can be recommended for broiler.Progressive Agriculture 28 (4): 323-330, 2017
