AbstractThe postnatal period is critical for broiler chicks as they are exposed to, possibly stressful, environmental changes in the hatchery and during transportation to the rearing houses. The ability of broiler chicks to spontaneously drink essential oils (EO) to mitigate the effects of a negative postnatal experience was tested. Chicks were either immediately placed in the rearing facility (C group), or subjected to a 24h-delay period before their placement (D group), mimicking the possible transportation delay in commercial conditions.In experiment 1, each group had access to either water only or to water and one EO (cardamom, marjoram or verbena) from D1 to D13. The verbena EO intake was higher in the D group than in the C group from D1 to D6 and the cardamom EO intake was lower in the D group than in the C group from D6 to D13.In experiment 2, half of the groups had access to water only and the other half was offered water and the 3 EO simultaneously. The EO were not differently chosen by chicks between D and C groups except a lower cardamom EO intake was observed in the D group than in the C group from D6 to D12. The delayed placement of the D group reduced chicken growth until 34 days of age and temporarily increased the feed conversion ratio, but did not affect their welfare or the prevalence of health disorders. The EO intake did not allow the chicks in the D group to overcome the growth reduction, but did overcome the reduction in Pectoralis major muscle yield. In conclusion, chicks are able to make spontaneous choices regarding EO intake according to their postnatal experience when EO are presented individually, but in our experimental design, they were not when EO were simultaneously presented. The EO intake only partially mitigated the decrease in chicken performance after the negative postnatal experience.

Convulsive Threshold

Few data are available in the literature describing the long-term effects of envenoming in the perinatal period. In this study, the relationship between envenoming of lactating rats and possible behavioral changes in the mother and in her offspring were investigated. Lactating Wistar rats received a single dose of T. serrulatus crude venom on postnatal days 2 (V2), 10 (V10) or 16 (V16), and had their maternal behavior evaluated. The seizure threshold was evaluated in adulthood offspring. A decrease in maternal care during envenoming was observed in V2 and V10 groups. The retrieval behavior was absent in the V2 group, and a lower seizure threshold in the adult offspring of all groups was observed. During envenoming, mothers stayed away from their offspring for a relatively long time. Maternal deprivation during the early postnatal period is one of the most potent stressors for pups and could be responsible, at least in part, for the decrease in the convulsive threshold of the offspring since stress is pointed to as a risk factor for epileptogenesis. Furthermore, the scorpionic accident generates an intense immune response, and inflammation in neonates increases the susceptibility to seizures in adulthood. Therefore, maternal envenoming during lactation can have adverse effects on offspring in adulthood.

In a randomized, prospective study the long-term effects of early post-partum skin-toskin and suckling contact was studied. In follow-up studies 36 hours, 3 and 12 months after delivery maternal behaviour, infant behaviour, the duration of breast feeding and certain attitudes towards child rearing procedures were shown to develop differently in a group of mothers and infants with early post-natal contacts as compared to a control group. Three years after delivery parents with early contact appreciated their children's language development to be faster; the number of siblings born in these families was greater than in controls. In the discussion, the relative importance of the immediate postnatal period is emphasized, a more family oriented development seems to occur in the presence of early post-delivery interaction.

New Brunswick lakes are subjected to multiple environmental stressors, such as atmospheric acid deposition and climate change. In the absence of long-term environmental data, the impacts of these stressors are not well understood. Long-term effects of environmental change on diatom species assemblages were assessed in the sediments of 16 New Brunswick lakes using paleolimnological approaches. A regional trend of increasing Cyclotella stelligera Cleve & Gunrow and decreasing Aulacoseira species complex was recorded in most lakes. Detailed paleolimnological analyses of Wolfe, Cundy, and West Long lakes revealed varying degrees of species change, with assemblage shifts beginning ca. 1900 CE (common era). These species trends are not consistent with acidification. However, linear regression of mean July temperature with time for two New Brunswick historical instrumental temperature records revealed statistically significant warming over the past century. The shift from heavily silicified tychoplanktonic Aulacoseira species to small planktonic diatom species, such as C. stelligera, is consistent with paleolimnological inferences of warming trends recorded in several other lake regions of the Northern Hemisphere. These assemblage shifts are likely due to recent climate change and may be mediated by reduced ice cover and (or) increased thermal stability (decreased lake mixing) during the open water period.

Factors Influencing

This review, which summarizes our findings concerning the long-term effects of pre-, peri- and postnatal factors affecting development, nociception and sensorimotor functions, focuses on three areas: 1) perinatal factors influencing nociception in adult rats were examined in rats with hippocampal lesions, after the administration of stress influencing and psychostimulant drugs (dexamethasone, indomethacine and methamphetamine); 2) the effect of pre- and early postnatal methamphetamine administration was shown to impair the development of sensorimotor functions tested in rat pups throughout the preweaning period; 3) the effect of extensive dorsal rhizotomy of the brachial plexus during the early postnatal period was studied with respect to neuropathic pain development and sensorimotor functions. The present study indicates that prenatal or neonatal stress, as well as various drugs, may disturb the development of the nociceptive system and cause long-term behavioral changes persisting to adulthood and that some types of neuropathic pain cannot be induced during the first two postnatal weeks at all. A mature nervous system is required for the development of the described pathological behaviors.

An experiment was conducted to assess the effects of thyme and peppermint essential oils (EO) as an alternative to antibiotic growth promoter (AGP) on the performance of broiler chicken. Total 256 day-old Vencobb broiler chicks were randomly distributed into eight experimental groups with four replicates of eight birds each. Experimental groups were fed with control diet without supplementation of AGP and essential oils (T1), BMD (Bacitracin Methylene Disalicylate) antibiotic @ 500 mg/kg diet (T2), thyme essential oil @ 150 mg/kg diet (T3), 200 mg/kg diet (T4), 250 mg/kg diet (T5), peppermint essential oil @ 200 mg/kg diet (T6), 250 mg/kg diet (T7) and 300 mg/kg diet (T8). The supplementation of thyme oil @ 200 mg/kg and peppermint oil @ 300 mg/kg broiler diet significantly (p less than 0.05) improved b.wt. and b.wt gain. The peppermint oil supplementation @ 300 mg/kg was found to be more beneficial when compared among different oil-supplemented groups. The feed conversion ratio was significantly (p less than 0.05) improved with peppermint oil supplementation @ 300 mg/kg diet. A significant (p less than 0.05) reduction in the mean abdominal fat was observed in diet supplemented with higher levels of thyme oil (@ 250 mg/kg diet) and peppermint oil (@ 300 mg/kg diet). Return over feed cost was the highest in broilers assigned diet with AGP; however, it was statistically similar to the basal diet. Considering the net return over fed cost of broilers, use of thyme oil was uneconomical, but supplementation of peppermint essential oil @ 200 and 300 mg/kg diet increased the net return over feed cost and were economical, however less as compared to T1 and T2.

Abstract Our previous work has indicated that feeding a blend of essential oils and a proprietary cobalt source (EOC) in combination with monensin (MON) may not be mutually beneficial to dairy calf growth performance. To evaluate this observation further, a 240 d long-term growth experiment was conducted using 12 young growing Holstein bulls using a 2 × 2 factorial treatment arrangement. Main factors were EOC (Rum-A-Fresh, Ralco, Inc., Marshall, MN) and monensin (MON; Norvikon Biotechnology Co., Hunan, China) arranged in 4 treatments: 1) Control: ration fed without EOC or MON; 2) EOC: EOC fed at 26 mg/kg DM; 3) MON: MON fed at 25 mg/kg DM; and 4) EOC+MON: EOC and MON fed in combination. Holstein bulls were 70 d of age and similar in BW (93.3 ± 4.54 kg) and individually fed for 280 d. Body weights, frame measurements, and blood samples were collected monthly. Interactions of EOC by MON were detected for BW, BW gain, ADG, and a trend for feed conversion. Bulls fed EOC or MON demonstrated greater final BW (367.7, 385.2, 381.2, and 357.5 kg for Control, EOC, MON, and EOC+MON, respectively), while BW gains (277.2, 291.5, 284.8, and 265.2 kg) and ADG (1.16, 1.22, 1.19, 1.11 kg/d) were greatest for bulls fed EOC or MON compared with bulls fed EOC+MON, with bulls fed Control being intermediate and similar to bulls fed MON. Intake of DM was greater for bulls fed EOC (6.55, 6.99, 6.60, and 6.42 kg/d) compared with bulls fed remaining treatments. Feeding EOC or MON separately can improve growth performance of growing Holstein bulls. Why the combination of EOC and MON is antagonistic to growth performance of Holstein bulls is unknown.

<p class="Els-1storder-head">Comparing these concepts with the usage of productivity assessment current design standards in implementing technological systems create concerns in safety performances [5]. The technology developmental risk was a concern in the Wright Brother era and the approach in implementing best solution practices based on simulating and testing standards to meet the goals in today’s operation is still an issue [4]. Effective modeling in promoting environmental changes for operational practices can present a risk concern in the developmental approach if productivity is not assessed [1]. Steps are needed to be taken to improve the environmental factors in the business efforts of promoting alternative energy; nonetheless, the long-term effects of not prioritizing the development standards on the global level may cause risk concerns in assessing aviation practice [1]. Realizing the sensitivity of the system development and the tradeoffs in implementing effective practices can also create awareness in the long-term efforts of environmental factors and its impact on operational cost improvements [10]. The ethical standards for human factors to improve the quality of people lives in addressing the challenges faced may be a concern going into the 21st century [7]. The tradeoffs of prioritizing can present both pros and cons; however, developmental practices are risky without modeling long-term impact and exploring different applications in adopting business practices [6]. Flexibility is an importance aspect in evaluating the productivity of long-term practices while using modern technology [6]. The productivity assessment impact in future implications and it influences to integrate traditional technology within the modern environment. </p><p> </p><p>Keywords: IT, aviation practices, promoting</p>
