A total number of 250 one day-old broiler cobb500™ chicks were used to study effect of nano silver on performance of growth and some physiological parameters of broiler chicks in the diet or drinking water under south Sinai condition. Chicks were randomly distributed into 5 equal experimental treatments of 50 chicks each. Every treatment was sub-divided into 5 replicates (10 chicks/ replicates), the chicks were housed in cages from hatch up to 5 weeks of age. The first group was fed the basal diet as a control(C), while, the other four treatments were fed diets containing either 10 and 15 mg/liter of drinking water silver (Ag NPs) for T1 and T2, respectively, while T3 and T4 treatments were fed on 10 and 15 mg / kg diets, respectively. Results obtained could be summarized as follows: Live body weight was increased significantly varied (P<0.01) among the different experimental treatment with the Ag NPs in drinking water and diets more than that of the control diet. Live body weight was improved with the Ag NPs level in the drinking water at 10 mg/ liter of drinking water and 10 mg/kg diets. Feed conversion ratio was better when given via the drinking water. Results on different growing period for clicks recorded significant differences in all carcass traits. Body weight and feed consumption were significant increase, synchronous with the increasing in thyroid hormone, total protein, IGG and AIGM. The same enhanced were in decrease of total lipid and cholesterol in blood, synchronous with the increasing in thyroid hormone; total protein; IGG and AIGM. The same enhanced were in decrease of total lipid and cholesterol in blood. The effect of the material used harmless to the birds and it is clear from the liver and kidney function means no side effects of the substance under study. In conclusion, View, the nano form of silver with 10 ppm/ liter of drinking water can be used on growth improve or some physiological parameters for broiler chicks under semiarid condition.

This research was guided to investigate the effects of supplementation of DL-methionine (DLM) and liquid DL-methionine hydroxy analog free acid (MHA) in diets on productive performance, hematological, blood metabolites and histological parameters in broiler chickens under summer conditions in Sina. A total number of 180 one day old Hubbard broiler chicks, with initial body weight (46.9 ± 2.5 g), were divided into 6 equal treatment groups. The treatment were DL-methionine (DLM) at 0.25% level, acid liquid methionine (ALM) and methionine hydroxyl analogue Ca salt (MHA) at 0.29 and 0.30%, respectively with and without dietary L-Threonine (0.0 and 1.0 g/kg diet). Chicks were raised for 35 days in battery cages under semi – arid conditions (high ambient temperature and relative humidity) in open-side housing. The obtained results indicate: The productive performance of DLM and MHA were not significantly different. Supplementation of DLM and MHA significantly improved final body weight, body weight gain, average daily gain, and feed conversion ratio when compared to the control group (P<0.01). The use of DLM enhanced the plasma methionine concentration (P<0.01) and increased the heterophil/lymphocyte ratio (P<0.05). While MHA elevated the plasma urea and uric acid concentration levels (P<0.05).

Plants have a crucial role in maintaining fitness of human beings in one way or other. These medicinal plants with complicated secondary metabolites provide medicinal and curative properties. Medicines based on plant and plant products, is the tradition of Kerala, which is now used as the basis of many of the modern medicaments. There are many plants, which are used by folklore for the treatment of cuts, wounds and burns that promote the repair mechanisms in the natural way. Since our traditional knowledge is on the verge of extinction, the present study was undertaken to document some of the medicinal plants used by Malapandaram tribal community settled at Adichipuzha, near Ranni to treat cuts and wounds.

The experiment was conducted to determine the effects of sesame meal supplementation on the production economy of broiler chickens. The study used a total of one hundred- and fifty-day-old Anak 2000 white strain unsexed broiler chicks which were randomly allocated to five dietary treatments of thirty broiler chicks per treatment and replicated three times with ten birds per replicate in a completely randomized design (CRD). Five experimental diets were formulated with toasted white sesame seeds meal (TWSSM) supplemented methionine at 0%, 4%, 8%, 12% and 16% in diets. The growth performance of the birds at starter phase were not significantly different (P?0.05) across all the treatments. At the finisher phase, the average daily feed intake (ADFI) differs significantly (P?0.001) among the treatment groups, while the average daily weight gain (ADWG) and feed conversion ratio (FCR) were similar. Feed cost (?431.49/kg gain) was higher in T5 (16%) TWSS while T2 (4%) TWSS had the lowest feed cost (?336. 54/kg gain). Thus, it was concluded that TWSSM could be a potential vegetables protein source for broiler chickens’ production and can be included in their diets at 4% as supplement for methionine without having effects on growth performance and equally reduces the cost of production.

Indiscriminate use of antibiotics in livestock and poultry farming has caused emergence of new pathogenic strains and resistance to other strains. This situation warranted the development of safe and alternative growth promoters and immunity enhancers in livestock production. Phytogenic additives in animal and bird feed is a centuries-old practice. Thus, this study investigated the efficacy of turmeric rhizome powder (Curcuma longa) as a natural growth promoter poultry feed additive. The study was designed on 112 one-day old chicks, assigned into four groups. Control group (T1) kept on basal diet only and groups T2, T3 and T4 fed with 0.5%, 0.75 and 1% TRP respectively on top of the basal diet for 45 days. Each dietary group consisted of four replicates of seven birds. Body weight, feed intake, blood biochemical analysis status of serum was investigated. In summary, we concluded that TRP can be used as a natural feed additive to improve growth performance in poultry, probably due to the better antioxidant activity and antimicrobial effects contributed by the better bioavailability of curcuminoids and turmerones. Beside these curcuminoids and turmerones act as gastroprotective and anti-inflammatory agents. The results obtained from this work show that lower inclusion rates of turmeric (0.5%) have a better potential on most of the observed parameters.

Antibiotic resistance has become an alarming issue in recent years, and the poultry industry is seeking alternatives in broiler feed to enhance growth and produce safe meat to meet consumer demand. Turmeric is one of the natural feed additives with the potential to improve broiler health and productivity. The present study was conducted to evaluate feed intake, weight gain, and feed conversion efficiency under different dietary treatment levels. A total of one hundred twelve (112) day-old chicks were used and divided into four treatment groups: T1, T2, T3, and T4, containing 0%, 0.5%, 0.75%, and 1% turmeric powder, respectively. Each treatment was replicated three times with seven birds per replicate in a completely randomized experimental design. A significant effect of turmeric powder on feed intake was observed (P < 0.05), whereas non-significant effects were observed on weight gain, body weight, feed conversion ratio, and feed efficiency at different levels of Curcuma longa powder supplementation. The experimental flocks were uniform and showed low variability in five parameters; however, the coefficient of variation (CV) for feed efficiency ratio was slightly higher at approximately 2.94%. The results of this experiment suggest that supplementation with 0.75% turmeric powder enhances feed intake in broiler chickens.

This study evaluated the haematological and serum biochemical indices of broiler chickens fed diets containing varying inclusion levels of sun-dried false yam meal (SFYM) as a partial replacement for maize. A total of 150-day-old broiler chicks were randomly assigned to five dietary treatments (0, 4, 8, 12 and 16% SFYM inclusion) in a completely randomized design (CRD), with three replicates of ten birds per treatment. Data on haematological indices showed that increasing SFYM levels led to a significant (P<0.05) decrease in packed cell volume (PCV), red blood cell (RBC), MCV, MCH, MCHC, and percentage heterophil, whilst the WBC increases. The mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) declined with increasing SFYM levels, indicative of a microcytic, hypochromic effect. Percentage eosinophil and lymphocytes were significantly (P<0.05) higher in broiler chickens maintained in T2 and T5 respectively compared to other treatment groups. The serum biochemical indices revealed (P<0.05) reduction in total protein, glucose, ALP, and AST of broiler chickens as the inclusion levels of SFYM increased, while the concentration of albumin, urea and creatinine increased. These findings suggest that SFYM can be used to substitute maize partially up to 16% level without negative impact on broiler chickens health.
