The present study was conducted to evaluate the effect of nisin, lactic acid and their combination on quality parameters and shelf life of broiler chicken breasts during chilling storage at 3 ± 1 °C. For achieving this goal, broiler chicken breasts were collected and divided into control and treated groups by dipping in each of 1% lactic acid, 2%lactic acid, nisin 50µg, nisin 100µg, nisin 50µg followed by 1% lactic acid, and nisin 100µg followed by 1% lactic acid. The samples were packaged and stored at 3 ± 1 °C. Control and treated groups were examined periodically at day zero and every three days until spoilage with chemical and microbiological methods. The results revealed that nisin, lactic acid and their combination improved the quality and extended the shelf life of broiler chicken breasts for 3 to 12 days during chilling storage. The use of nisin followed by lactic acid would be promising to provide a new hurdle technology for poultry meat decontamination.

The study was carried out to determine the physiological condition of the first female and male offspring of Japanese quail (Coturnix japonica) whose parents were supplemented by turmeric powder. This study consisted of two stages. In the first stage, 45 female quails aged 1 week were divided into 3 groups; P0: control; P1: supplemented by 54 mg turmeric powder/quail/day, P2: supplemented by 108 mg turmeric powder/quail/day. Each group consisted of 15 quails. Fertile eggs were collected from each treatment and incubated until hatched. Forty five females and 45 males offspring quails were collected from each treatment. The second stage consisted of 3 groups; K0: offspring of quail whose parents were not supplemented by turmeric powder (P0); K1: offspring of quail whose parents were supplemented by turmeric powder 54 mg/quail/day (P1); K2: offspring of quail whose parents were supplemented by turmeric powder 108 mg/quail/day (P2). This study implemented completely randomized design experimental method. It is proven that turmeric powder supplementation increased the levels of vitellogenin, HDL, vitamin B12, vitamin A, white egg protein, linoleic acid, arachidonic acid in eggs. In contrast, the cholesterol levels, LDL and total fat of eggs decreased. However, no significant changes of the oleic acid level were observed. On the second stage for both K1 and K2 in the case of the first female offspring of Japanese quail, the weight of carcass, SGPT, cholesterol serum, triglycerides serum and liver cholesterol increased, but LDL and SGOT serum decreased. Beside the weight of carcass, there were no significant changes for other parameters of the first male offspring of Japanese quail.

Poultry litter from rigorous poultry production plants has impact on environmental pollution. Feedstuffs for animal are getting with time expensive, to reduce the feed cost which could be achieved through the assimilation of relatively inexpensive and non-conventional feed ingredients, like poultry litter. The objective of this study was to explore the nutritive value of deep stacked broiler litter in ruminant’s total mixed ration. Four non castrated male sheep were used into 4×4 Latin Square Design (LSD) to 1 of the 4 dietary treatment groups that different in deep stacked broiler litter (DBL) as percentage of concentrate diet to investigate the nutritive value of DBL as a ruminant feed. The effect of dry matter intake and digestibility of DBL in sheep studied. Nitrogen retention was determined in total mixed ration at each level in the diets fed to sheep. Microsoft excels was used to balance experimental rations A, B, C, and D. Ration A was containing 0% DBL and served as control. Ration B contains 15% DBL, C was containing 30% DBL while Ration D containing 45% DBL. All the diets were prepared according to requirement of critical nutrients. All the diets were prepared isocaloric, isonitrogenous with or without DBL. Dry matter intake gradually decreased (P < 0.05) with the levels of broiler litter increased in the four diets. Means values of DMI (g/day) in rations A, B, C and D was 1040.7, 945.3, 840.9 and 786.8. Nitrogen retention (% of the total N consumed) were decreased (P < 0.05) as the broiler litter level increased in the diet. Up to 30% poultry litter in the supplement diets of sheep contributes as non-conventional source of nitrogen, and could be used for replacing traditional nitrogen sources like cotton seed cake. The findings of the present study suggested that inclusion of broiler litter up to 30% has no adverse effect on the health and apparent weight.

One hundred and twenty (120) day old Japanese quails were bought and allocated to four dietary treatments of thirty (30) birds per treatment with the aim of studying the growth performance and gastrointestinal tract morphometry of growing Japanese quails fed with graded levels of Moringa oleifera meal as partial replacement of dietary soybean meal. Each treatment had three replicates of 10 birds each in a completely randomized design. The experiment lasted for six weeks. Four diets containing 24% crude protein for the growing phase (0-6 weeks) were formulated in which Moringa oleifera leaf meal replaced soya bean meal at 0, 5, 10 and 15% as T0 , T1 , T2 , T3 respectively. The mean initial body weights, the mean final body weight and the mean total weight gains of the four treatments were significantly different from one another. However, feed conversion ratio, protein efficiency, performance efficiency factor and production number significantly varied across the four treatments; with T1 having the best result than the others. The mean spleen weights, mean breast weights, mean thigh weights, mean drumstick weights, mean wing weights and mean liver weights of the growing Japanese quails in the four treatments were not significantly different from one another except the heart weight of T1 . The mean weights, lengths, width and thickness of proventriculus, ventriculus, duodenum, jejunoileum, caeca and colon of the growing Japanese quails in the four treatments were not significantly different from one another, except the lengths of jejunoileum. It is therefore concluded that in growing Japanese quails, Moringa oleifera leaf meal may replace dietary soya beans meal up to 15%, with optimum level of 5% and no apparent adverse effects on gastrointestinal tract morphometry.
