The aim of this study was to evaluate the effect of lactic acid bacteria-based postbiotic supplementation on semen characteristics and hematological and biochemical profiles in rabbits. A total of 28 males were randomly allocated into two groups. Males received a Control diet and Enriched diet supplemented with postbiotic for 15 weeks (4 weeks of adaptation period and 11 weeks of experimental period). Body weight, feed intake and semen characteristics were recorded weekly. Hematological profile was recorded at the beginning and end of the experiment and biochemical profile at 0, 5, 10 and 15 weeks. Bayesian methodology was used for the statistical analysis. Feed intake was higher in Control diet (125.2 g) than in the Enriched diet (118.6 g, p = 1.00). The percentages of abnormal spermatozoa were higher in Control diet than in Enriched diet (30% and 22%; p = 0.93) and the acrosome integrity percentage was lower (97% and 96%; p = 0.87). The hematological profile was within the range for healthy rabbits. The plasmatic level of alanine aminotransferase was higher in Control diet than Enriched diet at 5 and 10 weeks (p = 0.93 and p = 0.94, respectively) and alkaline phosphatase was similar in Control diet throughout the experiment, but decreased in Enriched diet (p = 0.97). No difference was found in kidney parameters (uric nitrogen and creatinine). Enriched diet showed higher total protein and globulin than Control diet (p = 0.99). Phosphorus was lower (p = 0.92) in Control diet than in Enriched diet. In conclusion, the addition of the postbiotic based on lactic acid bacteria seems to improve the quality of the semen and the liver profile in rabbits.

Pelleted Diet

AbstractA grower diet containing barley, wheat and soya-bean meal was expanded at 110°C and subsequently pelleted at 80°C. This processing was evaluated in laboratory tests as well as in digestibility experiments involving 12 barrows with an average initial live weight of 40 kg. The unprocessed control diet was offered as a meal. Each diet was offered ad libitum to six pigs during a 5-week period. The 1st week was an adaptation period and measurements were not carried out. Each pig was used in two 5-day digestibility trials which were performed in weeks 2 and 4. Neither food intake, weight gain nor food: gain ratio during the whole 4-week experimental period, nor apparent faecal digestibility and apparent retention of protein were significantly affected (P > 0·05) by expanding and pelleting the diet. Processing caused an increase in the in vitro protein solubility (P < 0·05) and reduced the dietary contents of free lysine and methionine (P < 0·05) while the contents of available lysine and free threonine and tryptophan were not significantly changed (P > 0·05). Apparent faecal digestibility of crude fibre increased substantially (P < 0·05) when the diet was processed, resulting in significantly lower production of faecal mass (P < 0·05) as well as lowerfaecal moisture content (P < 0·05). These phenomena were parallelled by a smaller water consumption (P < 0·05). Apparent digestibility and retention of phosphorus and calcium were diminished (P < 0·05) when the diet was expanded and pelleted.

This work was carried out to evaluate the use of Bacillus subtilis probiotic C-3102 (10(10)cfu/g) in diets with or without growth promoters on the performance of broilers in the period from 1 to 42 days of age. It was used 1,200 Cobb line broilers, distributed in a complete randomized block with five diets: negative controller (without promoters); Bacillus subtilis (30 g/t ration); Bacillus subtilis (50 g/t ration); Bacillus subtilis (30 g/t ration) + colistin (10 ppm); avilamycin (10 ppm) + colistin (10 ppm). Each diet was evaluated in 10 repetitions with 24 birds. From 21 to 42 days of age, feed intake, weight gain and feed conversion were evaluated, and at 42 days of age, productive efficiency index was evaluated. At the end of the experimental period, it was observed an increase in the consumption of diet with the lowest dose of Bacillus subtilis (30 g) in relation to that one with Bacillus subtillis (30 g) + colistin (10 ppm). The values of weight gain obtained with the diet with the lowest dose of Bacillus subtillis (30 g) and with avilamycin (10 ppm) + colistine (10 ppm) were higher than those of the birds fed control diet (without promoters). For feed conversion, the best results were obtained by supplying diets containing 50 g of Bacillus subtillis, diet with 30 g of Bacillus subtillis + 10 ppm of colistin; and diet with 10 ppm of avilamycin + 10 ppm colistin. For the analysis of productive efficiency index, the best results were obtained with diets containing additives (probiotics and/or antibiotics) in comparison to the control diet. Bacillus subtillis C-3102 probiotic, at concentration 10(10) cfu/g, is an efficient substitute of antibiotics.

ABSTRACT. Penelitian bertujuan untuk mengkaji perkembangan bakteri usus halus dan performan ayam kampung silangan kampung-leghorn (KL) akibat ditambahkan ekstrak umbi dahlia dalam ransum. Ternak percobaan yang digunakan adalah persilangan ayam kampung silangan KL sebanyak 200 ekor umur 22 hari dengan rata-rata bobot badan 180,46 ± 1,21 g. Bahan perlakuan meliputi umbi dahlia, ethanol 70%, kertas saring halus serta bahan pakan penyusun ransum (jagung giling, bekatul, bungkil kedelai, tepung ikan, CaCO3 dan mineral dan vitamin mix). Rancangan percobaan yang digunakan rancangan acak lengkap dengan 4 perlakuan dan 5 ulangan (masing-masing unit percobaan diisi 10 ekor). Perlakuan yang diterapkan meliputi: P0=Ransum kontrol/RK, P1=RK+0,39% ekstrak umbi dahlia, P2=RK+0,78 ekstrak umbi dahlia, dan P3= RK+1,17 ekstrak umbi dahlia. Parameter yang diukur meliputi populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan pertambahan bobot badan harian (PBBH). Data dianalisis dengan menggunakan uji sidik ragam dan jika berpengaruh nyata dilakukan uji beda nyata Duncan pada taraf 5%. Hasil penelitian menunjukkan bahwa penambahan ekstrak umbi dahlia berpengaruh nyata terhadap populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan PBBH. Kesimpulan adalah penambahan ekstrak umbi dahlia sampai taraf 1,17% sebagai sumber inulin di dalam ransum dapat meningkatkan populasi bakteri asam laktat, menurunkan pH dan Escherichia coli pada masing-masing segmen usus halus serta memperlambat laju digesta dan meningkatkan PBBH.  (Population of small intestine bacteria and performance of native chicken-leghorn crossbreed duo to feeding of dahlia tuber extract) ABSTRAK. This study aims to examine the development of small intestine bacteria and the performances of native chicken-leghorn crossbreed due to the addition of dahlia tuber extract in the diet. Experimental animals were 200 unsex native chicken-leghorn crossbreed, 22 days old with an average body weight of 180.46 ± 1.21 g. Treatment materials include dahlia tuber, ethanol 70%, fine filter paper and feed stuff (yellow corn, rice bran, soy bean meal, fish meal, CaCO3, and vitamin-mineral mix). The present experiment was assigned in a completely randomized with 4 treatments and 5 replications (10 birds each). The treatments were: P0=Control Diet/CD, P1=CD+0,39% dahlia tuber extract, P2=CD+0,78% dahlia tuber extract and P3=CD+1,17% dahlia tuber extract. Parameters measured were the number of Lactic Acid Bacteria (LAB), Escherichia coli, intestinal potential hydrogen (pH) (duodenal, jejunal and ileal), rate of passage and daily body weight gain (DBWG). Data were subjected to ANOVA and followed by Duncan Multiple Range Test on 5% level. The results indicated that feeding native chicken-leghorn crossbreed with the diet containing dahlia tuber extract (DTE) significantly (P0.05) increased LAB population and DBWG, decreased E. coli population and intestinal pH, and slow the rate of passage down. In conclusion, feeding of dahlia tubers as a source of inulin in the form of dahlia tuber extract to a level of 1.17% increased the population of lactic acid bacteria, reduced pH and Escherichia coli in each segment of the small intestine and retard the rate of digestion and increased body weight gain.

In this study, the effect as growth promoter of five lactic acid strains (Enterococcus faecium, E. durans, Leuconostoc sp., Streptococcus sp. I and Streptococcus sp. II), isolated from intestinal tract of Nile tilapia (Oreochromis niloticus), was evaluated. Eight isocaloric diets were formulated: one containing 40% of protein as positive control, and seven with 27% protein. Five diets with 27% protein were supplemented with one of the isolated lactic acid bacteria in a concentration of 2.5x106 cfu g-1 of diet. A commercial probiotic based on S. faecium and Lactobacillus acidophilus was added at the same concentration to one 27% protein diet as a comparative diet, and the last diet was not supplemented with bacteria (negative control). Tilapia fry (280 mg basal weight) stocked in 15 L aquaria at a density of two per liter were fed for 12 weeks with experimental diets. Results showed that fry fed with native bacteria supplemented diets presented significantly higher growth and feeding performance than those fed with control diet. Treatment with Streptococcus sp. I isolated from the intestine of Tilapia produced the best growth and feeding efficiency, suggesting that this bacteria is an appropriate native growth promoter.

Public health concerns and the potential for food-borne zoonotic transmission have made Salmonella a subject of surveillance programs in food-producing animals. Forty-two piglets (25 d of age and initially 7.48 kg) were used in a 28 d infection period to evaluate the effects of a high proportion of rye on reducing Salmonella Typhimurium. Piglets were divided into two diet groups: control diet (wheat 69%) and experimental diet (rye 69%). After a one-week adaptation period, all piglets were orally infected with Salmonella Typhimurium (107 log CFU/mL; 2mL/pig). Salmonella in fecal shedding were evaluated at day 1, 3, 5, 7 and then weekly after infection. At the end of the experimental period (at day 28 after infection), the piglets were euthanized to sample feces, cecal digesta contents and ileocecal lymph nodes to determine the bacterial counts of Salmonella. The results suggest that the bacterial counts in the experimental group fed rye diets showed evidence of reducing Salmonella fecal shedding from day 14 onwards and decreasing the number of Salmonella in cecal digesta. However, the translocation of Salmonella in ileocecal lymph nodes was not affected. Furthermore, feed intake, weight gain and feed conversion did not differ between the groups (p > 0.05).

Lysophospholipids (LPL), a new feed additive, were supplemented to a pelleted total mixed ration (TMR) of dairy cows to examine its effects on feed intake, production, and composition of milk and plasma biochemical parameters. Two dietary treatments included diets supplemented without (control diet; CON) or with LPL at a dose of 0.5 g/kg of pelleted TMR. Twelve multiparous, mid-lactation, Holstein cows (Bodyweight 730 ± 9.3 kg; 100 ± 6.0 days in milk) were randomly assigned to one of the two dietary treatments with a 42-day measurement period after a 14-day adaptation period. Feed and water were provided ad libitum. Feed intake and milk yields were recorded daily, blood samples were collected fortnightly, and milk samples weekly. The results showed that the supplementation of LPL did not change feed dry matter intake, milk yields, and milk composition. However, it increased total protein and globulin and the activity of alkaline phosphatase and decreased total cholesterol in plasma. This study suggests that LPL may have beneficent effects in animal health but might be not a feasible feed additive to increase production for dairy cows fed a pelleted TMR.

A total of 60 weaned piglets (28-day old; [Landrace ×Yorkshire]×Duroc) were used to evaluate the efficacy of Bacillus-based probiotic on performance, digestibility, blood profiles, and fecal microbiota in weaned pigs. The piglets were randomly allotted to three treatments with 4 pens per treatment and 5 pigs per pen. Dietary treatments consisted of: CON, basal diet; BS, basal diet + 0.1% of Bacillus subtilis RX7; BM, basal diet + 0.1% of Bacillus methylotrophicus C14. The average daily feed intake (ADFI) was reduced (P=0.01) in BS and BM treatments compared with CON. The apparent total tract digestibility of energy was increased (P less than 0.05) in BS and BM compared with CON on day 14. The supplementation of probiotics led to increase (P less than 0.05) in fecal lactic acid bacteria counts on day 42. In conclusion, probiotic supplementation reduced feed intake, increased energy digestibility and lactic acid bacteria counts and numerically reduced Salmonella counts in weaned pigs.

<p><em>This study examined the effect of live <em><em>Lactobacillus paracasei</em></em> NFRI 7415 on the preference of a lard diet (LD) and a fish-oil diet (FD) in rats. 4-week-old male Fischer 344 rats were fed one of four diets; LD, LD + lactic acid bacteria (LLD), FD and FD + lactic acid bacteria for 4 weeks (dietary experimental period). The LLD and FLD groups freely ingested water containing <em><em>Lb. paracasei</em></em> NFRI 7415 (10<sup>7</sup> cfu/ml). After 4 weeks, all rats were placed on a two-choice diet program in which they self-selected from two food cups, each containing either the LD or the FD for 5 weeks (self-selection period). After the dietary experimental period, there was no significant difference in the final body weight and total food intake among the four groups. The intake of fish-oil and live <em><em>Lb. paracasei</em></em> NFRI 7415 was increasing the fecal lipids excretion, and it effectively reduced plasma total cholesterol concentration (p&lt;0.05). It was indicated that the intake of live <em><em>Lb. paracasei</em></em> NFRI 7415 was no influence on the preference for fat in the dietary experimental period and the self-selection period.</em></p>
