“…Livability results (Table 2) show the lack of detrimental effects in linseed and pumpkin seed meals used in the present experiment in birds. These results coincide with Aguilar et al (2011) and Ahmad et al (2013) who did not find morbidity and mortality in the birds with levels of up to 100 g/kg of PSM and LM in the feed, respectively. Although, both oilseeds have secondary metabolites, high concentrations cause symptoms related to antinutritional factors, such as tannins, saponins and trypsin inhibitors and phytic acid, phytostereogenic and linamarin, respectively, and has been recommended by nutritionists up to 100 g/ kg in the diet (Novak & Scheideler, 2001;Martínez et al, 2010a).…”

This study was conducted to determine the effects of dietary inclusion with linseed and pumpkin seed meals on growth performance, carcass traits and breast meat fatty acids profile of helmeted guinea fowls. A total of 120 meat-type helmeted guinea fowl females of 12 weeks of age were fed with 0 (T0), 100 (T1) and 200 (T2) g/kg of linseed (LM) and pumpkin seed meals (PSM) for 56 days, in a completely randomized design with 10 replicates per treatment and four birds per replicate. The inclusion up to 200 g/kg of LM and PSM did not affect the livability, initial live weight and feed intake (p>0.05). However, final live weight and feed:gain ratio improved significantly (p<0.05). The T1 increased (p<0.05) the carcass yield and the T2 improved the breast weight and weight and yield of leg. Also, these experimental diets did not affect the carcass weight, breast yield and sensory quality of meat (p>0.05). The oleaginous seeds (LM and PSM) decreased (p<0.05) the mystic, palmitic and octadecanoic acids and the ω-6/ω-3 ratio, as well as increased the linoleic, α-linolenic, eicosapentanoic and docosahexanoic acids (p<0.05), but did not modify the concentration of monounsaturated fatty acids (p>0.05) and the eicosatrienoic and arachidonic acids in breast meat (p<0.05). It is recommended the inclusion of 100 g/kg of LM and PSM to improve the live weight, weight and yield of the edible portions and the essential fatty acids in breast meat of guinea fowl, without affecting the sensory quality of the meat.

Beef is one of the essential sources of protein in human diet. But retail beef are easily contaminated with pathogenic bacteria and can cause foodborne disease. To determine the bacterial contamination, 45 samples of retail beef including imported beef (n = 24) and local beef (n = 21) were collected from selected wet markets at every district in Selangor. Samples were analyzed for total viable counts (TVC), Escherichia coli, Enterobacteriaceae and the incidence of pathogenic bacteria which are Salmonella spp. and E. coli O157:H7. Overall results showed that all beef samples (n = 45) were positive for TVC and Enterobacteriaceae at an average reading of (mean ± SD) 7.05±0.78 log CFU/g and 5.05±0.87 log CFU/g, respectively. Only 53.3% of the total samples were contaminated with E. coli (4.22±0.60 log CFU/g) whereas only 24.4% of total samples were found to be positive with Salmonella spp. All bacterial count readings fall under the marginal category based on the international standards. There were no significant differences (p > 0.05) in microbial counts between the local and imported beef samples for all parameters. Among the E. coli isolates detected from the beef samples, 3 isolates were identified as E. coli O157:H7. In conclusion, meat safety level for the retail beef sold at wet markets in Selangor and Kuala Lumpur is low and requires more attention from the authorities to ensure its microbiological safety for consumers.

“…Considering that this synthesis process is relatively inefficient in human body, there are the increasing attempts to improve the FA composition of eggs by inclusion of different vegetable sources in hens diet. Among the numerous dietary supplements for laying hens, linseed (Ahmad et al, 2013), fish oil (Kralik et al, 2008) and marine algae (Lemahieu et al 2013) are reported to contribute successfully to enhancing n-3 PUFA content in egg yolk.…”

SummaryEggs enriched with n-3 fatty acids and natural pigments are desirable in human food chain due to numerous benefits for health. In this study, we investigated the effects of inclusion of co-extruded linseed and sunflower meal into laying hens’ diet and replacement of synthesized pigment with paprika and marigold flower as sources of natural pigments. Four hundred 18–wk-old Bovan laying hens divided in two groups (control and experiment) were fed for 12 weeks. Fatty acids and β-carotene were monitored every fourth week and successively analyzed. Significantly (p<0.05) increased content of α-linolenic acid in egg yolk in the experimental group in comparison to the control group was observed with addition of linseed, paprika and marigold in laying hens’ nutrition. Nearly the same tendency was observed in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content. Supplementation of the co-extruded linseed and sunflower meal into laying hens’ diet demonstrated significantly (p<0.05) lower n-6/n-3 FA ratio in experimental group compared to control group. The obtained results showed that the synthetic pigment added to laying hens’ diet provided better pigmentation of egg yolks after one and two months of the feeding trial than paprika and marigold flower. The concentration of β-carotene in egg yolks increased in experimental group after three months of the treatment, and that was the first time that concentrations of β-carotene did not significantly (p < 0.05) differ among control and experimental group, which shows that paprika and marigold flower as sources of natural pigments can successfully replace synthetic pigment. We shall continue research in this field with other supplemented mixtures, as there are indices for other potential feed enhancements among oily seeds and herbs.
