The level of production in a variety of organic production systems is often lower than in other traditional production systems. In poultry production, there is also a direct negative effect of the small scale regarding sustainable organic poultry production. Regardless of differences between organic and conventional production systems, this experiment aimed to investigate the usage of tea tree Melaleuca alternifolia (Maiden and Betche) Cheel essential oils as a natural alternative to antibiotics in hen nutrition on productive parameters, table egg quality and eggs fatty acid profile as a promising sustainable organic agricultural tool. A total of 360 Lohmann Brown hens, aged 54 weeks, divided into three different treatment diets, were supplemented with 0 (T1), 40 (T2) and 80 mg/kg (T3) of M. alternifolia essential oil, respectively. Experimental treatments were replicated four times within 30 birds each. The experiment lasted for a total of 56 days (55 to 62 weeks of hens age). A 56-day experimental had two timetable periods of 28 days each: period 1 (55 to 58 weeks of hen age) and period 2 (59 to 62 weeks of hen age). For compound feed supplemented with M. alternifolia essential oil, daily egg production and the efficiency of nutrient utilization (FCR) was improved significantly (p < 0.05) until the end of week 58, with a significant (p < 0.05) increase in the thickness of eggshell, as well as egg production (p < 0.05). However, egg mass, feed consumption, FCR and albumen height, Haugh unit, and eggshell strength did not show any significant (p > 0.05) differences influenced by essential oil feed supplementation. Lower concentrations of saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA), and higher concentrations of polyunsaturated fatty acid (PUFA), were recorded with M. alternifolia essential oil supplementation, but without significant (p > 0.05) differences. At the end of the experiment, the obtained results showed that the addition of M. alternifolia essential oil to hen nutrition had a positive effect on production parameters and eggs fatty acid profile, with increased eggshell thickness (p < 0.05).

Food function is nowadays not merely limited to nourishment supplying; consumers’ interest is oriented to food healthiness and nutritional value, animal welfare, environmental impact of animal productions, and products’ traceability. The objective of the present work is to compare physical parameters and fatty acids profiles of market eggs produced from hens housed in four different systems. In addition, the effects of the presence of an outdoor space allowance (IND = no outdoor space allowance, OUT = outdoor space allowance) on the same parameters have been investigated. Sixty-nine market eggs from four different production systems labelled as Alternative (ALT), Enriched Cage (ECA), Litter Floor (LIF), and Organic (ORG) have been analysed. Physical parameters and fatty acid concentrations were measured. An ANOVA analysis was performed with production system and outdoor space allowance as sources of variation, two Principal Component Analyses (PCA) were carried out with physical parameters and fatty acid parameters as variables. The effects of the complex interactions occurring among production system, hen welfare, and eggs quality have been analysed in marketed eggs leading to the conclusion that eggs from different production systems available on the market are characterized by differences in fatty acid profile and physical parameters. In physical parameters the differences among systems were influenced by the whole egg weight, albumen weight and yolk weight. In fatty acids parameters the determining variables are the content in polyunsatured fatty acids (PUFA), linoleic acid concentration, and n6/n3 ratio.

In poultry production, the intensive use of high-performing hybrid animals led to loss of genetic variability and a consequent lower response to climatic change and disease. Poultry biodiversity is seriously threatened, and its safeguard is a strong objective in developed countries. According to the FAO, which emphasized the importance of native breeds for its country of origin, the aim of this study was to present the first contribution on eggs quality for endangered the Siciliana chicken breed and deepen knowledge on the local Livorno breed. At 20 weeks of age, 108 laying hens (54 Siciliana breed and 54 Livorno breed) were divided into six homogeneous groups of 18 hens each and reared according to requirements imposed by the EC Regulation 889/08 for organic production. The production cycle was controlled over one year, and egg production was recorded daily by group. Eggs were collected, weighted, and measured. Physico-chemical parameter and fatty acids profile were analyzed and nutritional indexes calculated. The statistical model included the effects of breed (Siciliana, Livorno). Egg production was 190 egg/head for Siciliana and 180 for Livorno group. The results showed similar values for Siciliana and Livorno egg quality, highlighting several valuable quality traits from these breeds which might be taken into account for conservation programs.

Synthetic Pesticides

Conventional pest management (the use of synthetic pesticides) is being increasingly hampered by issues of pest resistance, tighter legislation and greater consumer demand for food stuffs produced in an environmentally friendly manner. A growing body of research suggests that essential oils may be of use as an alternative to synthetic products in managing the poultry red mite (Dermanyssus gallinae), a serious pest of egg production systems for laying hens (Kim et al., 2004). It is necessary to ensure that any essential oil recommended as an acaricide against this pest does not taint the eggs produced from hens in poultry units in which the oil would be deployed. The aim of the current study was to test the hypotheses that thyme and pennyroyal essential oils, having been found to be effective as acaricides for D. gallinae in preceding work, would have no effect on the occurrence of taint in hens’ eggs.

Summary Organic farming represents agricultural practice that could contribute to the preservation of biological diversity and breeding of cows with the most desired milk quality attributes. Milk composition could vary widely according to genetic diversity of the animals and different feeding systems. These are related to higher dry matter content, fat, protein and a more favorable ratio of the saturated/unsaturated fatty acids, which is important in traditional cheese production. Standard chemical analyzes were performed and this paper shows the differences in the chemical properties and the fatty acid profile of milk, depending on the different breeds and breeding methods of animals. Simmental milk (indoors) was most abundant in dry matter and fat (13.01 and 4.30%, respectively) while protein and casein level was the highest in the Busha milk (3.67 and 2.63%, respectively). Holstein Friesian milk (organic) possessed a more constant composition and, together with Busha appropriate hygienic quality of milk (low level of somatic cells and total bacteria count). Also, milk from Holstein Friesian cows (organic) was disposed with better nutritional quality and more desirable fatty acid profile (SFA (63.40%), MUFA (30.79%) and PUFA (5.72 %)). On the other hand, Holstein Friesian (conventional) milk contained SFA (67.45%), MUFA (29.27%) and PUFA (3.28%) while Simmental (indoors) higher values of SFA (71.21%) and less MUFA (25.39%) and PUFA (3.40%). There are various ways to preserve biodiversity and the application of organic production standards in the traditional cheese production contributes to obtaining safer, quality products which are more recognizable on the market.
