Tannins have shown numerous biological activities and are very appreciated in food animal production, especially for their antimicrobial, antiparasitic, antioxidant, anti-inflammatory and antivirus effects. The aim of the present study was to evaluate the effect of two levels of dietary Quebracho tannin (QT) on growth and performance traits, and possible effects on intestinal parasite load in Italian White Livorno pullets. A 140-day trial was carried out on 180 35-day-old females, fed on two levels of dietary QT inclusion: 0%, 1% and 2%. Birds were reared under free-range conditions. Dietary Quebracho tannin may be used up to 1% in growing female White Livorno chickens without any adverse effects. The results observed in this study on the use of dietary QT at 2% might have not reflected the real effect on performance traits due to the initial inclusion of dietary QT at 3%. Nevertheless, by reducing QT to 2%, a progressive normalization of body weight gain, feed intake and feed conversion ratio was observed, resulting in compensatory growth. QT was demonstrated to drastically reduce fecal outputs of Nematodes eggs (Ascaridia spp. and Heterakis spp.) and Coccidia oocytes (Eimeria spp.). The inclusion of 2% produced highly dry droppings.

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%.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.

The aim of this study was to evaluate poultry performance and diet metabolisability in slow- growing naked neck chickens fed different substitution levels of soybean meal protein with cottonseed cake protein. The trial was conducted in a completely randomized design with five treatments (0, 10, 20, 30 and 40% substitution of soybean meal protein with cottonseed cake protein), six replicates and fifteen birds per replicate. The birds and diets of each experimental unit were weighed at one day old. At 30, 60 and 85 days old, the chickens and leftovers were weighed again to estimate the feed intake (FI), weight gain (WG), feed conversion (FC) and final weight (FW) from 1 to 30 days, from 1 to 60 days and from 1 to 85 days old. To evaluate diet metabolisability, a three-day total excreta collection (26 to 28 days of age) was performed. A quadratic effect was reported for diet metabolisability, in which the minimum substitution level was 17.45% and 17.69% for apparent metabolisable energy (AME) and nitrogen-corrected apparent metabolisable energy (AMEn), respectively. Based on performance, it is recommended to replace 40% soybean meal protein with cottonseed cake protein.

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.

Numerous non-antibiotic feed additives (alternatives to antibiotics, ATAs) have been marketed, but few have been evaluated under uniform testing conditions modelling commercial flocks. We compared 24 ATA treatments and the ionophorous coccidiostat narasin against a diet without any feed additives. Feed conversion ratio and body weight gain were registered from day 0 to 28 in Ross 308 chickens housed on litter floor. The chickens were challenged with Eimeria spp., and cecal Clostridium perfringens (CP) counts were investigated. Active components from all ATA classes had a positive impact on intestinal health or production performance. Whereas narasin had a strong CP-reducing effect in combination with performance-promoting impact, only two ATA treatments achieved significantly beneficial effects on CP counts as well as feed conversion during the time span following Eimeria challenge. Active components present in these two treatments include a Bacillus subtilis probiotic strain, short- and medium-chain fatty acids and Saccharomyces cerevisiae components. Different ATA classes had beneficial impact during distinct rearing phases and on specific performance targets, suggesting that optimizing combinations and use of active components can make ATAs even more useful tools in broiler rearing without the use of in-feed antimicrobials. Further studies of promising ATAs and ATA combinations are required.

This study examined the relationship between carcass composition and performance traits of local turkey fed starter diet (30.2% protein, 2950 kcal/kg ME). At 8 week of age, male and female chicks were separated and reared in individual cages until 16 weeks of age. At the end of the experiment, the birds were slaughtered and carcasses were analyzed for chemical composition to predict chemical composition (moisture, ash, protein and fat) from performance traits such as initial body weight (g) at 8wk, final live body weight (g) at 16wk, daily weight gain (g), daily feed intake (g), feed conversion ratio, daily protein intake (g), protein conversion ratio, dressing-out percentage. There were significant correlations between moisture, protein and fat; between ash, protein, fat and dressing-out percentage; between protein, fat and dressing-out percentage; between fat, moisture, ash, protein, live body weight, feed conversion ratio, protein conversion ratio and dressing-out percentage. Although the coefficient of correlation (R2) for prediction equations was not high, the moisture content equation depends on feed conversion ratio while for ash, protein and fat depends on dressing-out percentage.

Glucomannan is consisted of D-glucose and D-mannose with β-1.4 linkages. Poultry had no enzyme to digest β linkage so that porang (Amorphophallus onchophyllus) glucomannan could be a prebiotic candidate. The study purposed to determine the effect of porang glucomannan on caecum bacterial composition (similarity, diversity, grouping of bacteria) using Terminal Restriction Fragment Length Polymorphisms method and performance (body weight gain, feed intake, feed conversion ratio) of broiler chickens. One hundred and eighty unsexed day old chicks (DOC) were divided into 6 treat-ments and 3 replicates (10 birds each) using completely randomized design (CRD). The treatments were P0 (basal feed), P1 (basal feed + 0.05% porang glucomannan), P2 (basal feed + 0.1% porang glu-comannan), P3 (basal feed + 0.15% porang glucomannan), KJ (basal feed + 0.1% commercial konjac glucomannan), and KM (commercial feed). The results showed that caecal bacterial composition of porang glucomannan treatment had similarity with konjac glucomannan and basal feed. Diversity index and species number of porang glucomannan treatment was higher than konjac glucomannan. Gluco-mannan prebiotics had higher Lactobacillus while the lowest Clostridium was obtained in 0.1% porang glucomannan treatment. The inclusion of glucomannan prebiotics gave no negative effect on the per-formance of broilers.

Four trials (two at the starter phase and two at the finisher phase) were carried out in a study that utilized Anak-180 broiler chickens to evaluate the potentials of six limestone sources (that were procured from Ashaka, Calabar, Jakura, Sokoto, Ukpila and Yandev cement factories) for inclusion in broiler diets as calcium source. The control diet accounted for the seventh dietary treatment. The first chick trial (Trial 1) utilized 525 chicks and the second (Trial 2) utilized 420 chicks from day old to 28 days of age. Dietary treatments in each trial were replicated 3 times such that Trial 1 had 25 chicks per replicate and Trial 2 had 20 chicks. The first finisher trial (Trial 3) utilized 315 chickens with 15 birds per replicate, the second (Trial 4) utilized 252 chickens with 12 birds per replicate from 35 days of age to 56 days. The experimental design was Completely Randomized Design. Measurements were taken for, feed intake, body weight gain, efficiency of feed conversion, leg disorders and mortality rate. Results indicated significant (P<0.05) differences in feed intake and weight gain in trial 1. In trial 2, all performance traits were significantly (P<0.05) different among the diets. Both leg disorders and mortality rate occurred in trial 1 but were mild in trial 2. There were no significant (P>0.05) differences among the limes in the performance traits in trial 3, but trial 4 showed significant (P<0.05) differences among the dietary means for feed intake, and weight gain. Generally, the study showed improved performance traits over suggested bench mark standard in this country. Leg disorders did not affect performance traits adversely; both leg disorders and mortality rate were adjudged to be independent of limestone sources tested. It was concluded that, the limestone sources tested were good calcium sources for broiler diets.
