Effect Of Age

This study aimed to determine the effect of age on the immune and visceral organ weights and cecal traits in modern broilers. 200 male Ross® 308 broilers were randomly selected, then 20 broilers were slaughtered every day (up to 10 days old) after six hours of fasting. All the organs measured had a progressive increase in absolute weight as the days progressed, apart from the spleen, which decreased its absolute weight on day 5, even though on day 10 it showed the highest values. Moreover, the small intestine relative weight increased from the fourth to the ninth day and was correlated (p ≤ 0.05) with the relative weight of the proventriculus, gizzard, small intestine, and cecum, although without statistical association with the of the heart. There was a correlation between the cecum relative weight and the cecal lactic acid bacteria, and between the primary lymphoid organs. The pH (from 5.74 to 7.40) and cecal lactic acid bacteria (from 6.11 to 8.79 log 10 CFU/g) changed according to the age of the broilers. The results could contribute to the understanding of the physiology and intestinal microbiology of the first 10 days old of modern broilers, which is crucial to improve the genetic expression of these animals.

The association of salmonella infections with the consumption of poultry products and the fact that in the live bird the Salmonella carriage is mainly asyptomatic have led to a demand for finding ways of preventing infection of commercially reared poultry and product contamination (Revolledo et al., 2006). One approach is the use of probiotics. The probiotic properties of lactic acid bacteria have been widely studied. Their capacity for adhesion to mucus, ability to autoaggregate and potential for coaggregation with pathogenic bacteria are potential mechanisms for providing a competitive advantage in the intestinal microbiota (Ghadban et al, 2002) and forming a barrier that prevents colonization of pathogenic microorganisms (Kos et al, 2003). In this study, a total of 53 lactic acid bacteria (LAB) were isolated from the contents of the crop, caecum and small intestine, and from the mucosa of the crop, jejunum and ileum of three organically farmed chickens, were examined for autoaggregation and coaggregation with Salmonella enteritidis.

Effect Of Age

This study evaluated the potential effect of age of cook-in-bag ham and turkey breast delicatessen meats formulated with lactate-diacetate on survival and/or growth of Listeria monocytogenes introduced after opening of packages and slicing of product. Commercially prepared cured ham and turkey breast products formulated with potassium lactate and sodium diacetate were stored at 1.7°C unsliced, in their original cook-in-bags, and without postlethality exposure. On days 5, 90, 120, and 180 of storage, product slices (10.2 by 7.6 cm) were surface inoculated (1 to 2 log CFU/cm2) with a 10-strain mixture of L. monocytogenes, vacuum packaged (seven slices per bag), and stored at 4°C for up to 13 weeks. Inoculated levels of L. monocytogenes on both products were 1.4 to 1.5 log CFU/cm2. Irrespective of product age at slicing and inoculation, after 13 weeks of vacuum-packaged storage (4°C), pathogen counts on product slices were 1.5 to 2.3 (ham) and 2.3 to 2.5 (turkey) log CFU/cm2. Overall, the results of the study showed that the age of the cook-in-bag products prior to slicing and inoculation with the pathogen did not (P ≥ 0.05) affect the behavior of L. monocytogenes during vacuum-packaged storage (4°C, up to 13 weeks) of ham and turkey slices. Mean counts of lactic acid bacteria and yeasts and molds, when detected, did not exceed approximately 1 and 2 log CFU/cm2, respectively, among all stored samples. Findings of the study will be useful to the meat industry and risk assessors in their efforts to control L. monocytogenes in ready-to-eat meat products.

This study aims to evaluate the use of cassava peels added with lactic acid bacteria on the immune organ weight of super native chickens. The material used in this study was 144 Day Old Chick (DOC) super unsex native chicken with an average body weight of 34 ± 3,14 gram. The research design used was a completely randomized design (CRD) with a dose of liquid feed additive in the form of a combination of cassava peel flour and lactic acid bacteria mixed with rations. The treatments in this study included T0: basal ration, T1 (basal ration + 10% feed additive ml/kg), T2 (basal ration + 15% feed additive ml/kg) and T3 (basal ration + 20% feed additive ml/kg). The parameters observed were body weight, the relative weight of lymph, thymus, and bursa Fabricius superficial chicken stock exchange. The result showed that the combination of cassava peel and lactic acid bacteria had no significant effect (P>0.05) on body weight, the relative weight of the lymph organs, thymus, and bursa Fabricius of super native chickens. This research concludes that the combination of cassava peel and lactic acid bacteria as a feed additive can maintain chickens' health by not increasing the relative weight of the super native chicken immune organs to the level of 200 ml/kg.

Piglet Mortality

The perinatal mortality of cloned animals is a well-known problem. In the present retrospective study, we report on mortality of cloned transgenic or non-transgenic piglets produced as part of several investigations. Large White (LW) sows (n = 105) received hand-made cloned LW or minipig blastocysts and delivered either spontaneously or after prostaglandin induction followed by either Caesarean section or vaginal birth. The overall pregnancy rate was 62%, with 26% of pregnancies terminating before term. This resulted in 48 deliveries. The terminated pregnancies consisted of 12 abortions that occurred at 35 ± 2 days gestation and five sows that went to term without returning to heat and then by surgery showed the uterus without fetal content. The gestation length was for sows with LW piglets that delivered by Caesarean section or vaginally was 115.7 ± 0.3 and 117.6 ± 0.4 days, respectively. In sows with minipiglets, the gestation length for those delivered by Caesarean section or vaginally 114.4 ± 0.2 and 115.5 ± 0.3 days, respectively. Of the 34 sows that delivered vaginally, 28 gave birth after induction, whereas 6 farrowed spontaneously. Of the 14 sows that delivered after Caesarean section and in the five empty sows, the endometrium and placenta showed severe oedema. Piglet mortality following vaginal delivery was higher than after Caesarean section (31% v. 10%, respectively; P < 0.001). When vaginal delivery occurred spontaneously, the stillborn rate was greater than after induced delivery (56% v. 24%, respectively; P < 0.0001). Internal organ weights were recorded for seven cloned LW piglets and six normal piglets. The relative weight of the heart, liver, kidneys and small intestine was found to be reduced in the cloned piglets (P < 0.05). The present study demonstrates extensive endometrial oedema in sows pregnant with cloned and transgenic piglets, as well as in empty recipients, at term. The growth of certain organs in some of the cloned piglets was reduced and the rate of stillborn piglets was greater in cloned and transgenic piglets delivered vaginally, possibly because of oedema of the fetal–maternal interface.

The extent to which lactic acid bacteria, intestinal bacteria, and yeast from the gastrointestinal tract of rats suppress the absorption of 3-amino-1,4-dimethyl-5H-pyrido(4,3-b)indole (Trp-P-1) was investigated. Trp-P-1 was absorbed from the small intestine very rapidly, but in the stomach it was slowly absorbed, requiring 1 or 2 h after administration. When mixtures of Trp-P-1 and freeze-dried microorganisms were administered to rats for 1 h, the amounts of Trp-P-1 absorbed from the small intestine were significantly reduced, and the levels of Trp-P-1 in blood decreased by 40.4–64.7% compared with a control in which only Trp-P-1 was administered. There were no significant differences between the organisms used. In vitro, freeze-dried cells of the strains tested bound 51-97% of Trp-P-1. The Trp-P-1 bound to cells was effectively extracted by aqueous methanol, ethanol, ammonia (50 g/L), and solutions of MgCl2 and CaCl2 (100 mM/mL), but little was extracted by water and solutions of KCl, NaCl, and buffers at various pH values.Key words: Trp-P-1, gastrointestinal absorption, binding, intestinal bacteria, mutagen–carcinogen.
