Hematological alterations in broiler chicks during different seasons supplemented with herbal formulations
Nidhi Singh1,J.P.Singh2 and M.K.S. Rajput3
Veterinary World , 2008,
Abstract: The study was conducted on Vencobb broiler chicks to ascertain the antistress affects of Zist, Zeetress and a combination of Amla and Turmeric during summer, rainy and winter seasons and thereby the haematological changes of birds revealed that during all the three seasons a marked improvement in Haemoglobin was encountered in all the three groups where herbal preparations were supplemented. A marked increase in the lymphocyte count occurred during summer and winter seasons in all the experimental groups of bird as compared to the control group. The heterophil count was decreased with the supplementation of herbal formulations in the feed irrespective of the seasons encountered in the season. This decrease in heterophil count was highly significant in seasons like summer, winter and rainy. This observation proves the hepato-stimulatory, hepato protective and immuno modulating effects of herbal preparations. [Veterinary World 2008; 1(4.000): 110-112]

Abstract: the presence of salmonella species in feeds and ingredients is an important source of salmonella contamination for animals. organic acid mixtures have shown to be an effective alternative to eliminate salmonellas in feeds and chickens. in the present study, the performance of male broiler chickens receiving levels (0, 0.25, 0.50, 1.0 and 2.0%) of a mixture of organic acids (oas) (70% formic acid and 30% propionic acid) in the diet was evaluated from the age one to 42 days, in a completely randomized experimental design with five treatments and five replications of 40 birds each. diets were based on corn, soybean meal and soybean oil. body weight, weight gain and feed intake from the age one to 21 days were affected by the treatments; 2% oas in the diet reduced body weight and weight gain. feed intake increased with concentrations of 0.25 and 0.5% and was reduced with 2% of oas. from the age one to 42 days, only feed intake was affected, showing a quadratic effect, increasing at the levels of 0.25 and 0.5% and decreasing at 2% of oas. the mixture of oas at doses which are effective for the control of salmonella did not affect chicken performance, and the inclusion of 1% oas in the diet resulted in a performance similar to that of untreated birds.

Journal of Animal and Veterinary Advances , 2012,
Abstract: A study was conducted to evaluate the utilization of Dried Yeast (DY) as a source of lysine in broiler feeds. Three feeds, control (0.0% lysine and 0.0% DY), 0.25% Lysine and ).25% DY were compounded and tested on 270.0 Ross broiler chicks for 56 days. Data were collected on the proximate, calcium, phosphorus, amino acid composition of the feeds, performance and feed utilization of the broilers. It was observed that substitution of DY for lysine at 0.25% had no significant (p>0.05) effect on the proximate, calcium and phosphorus levels of the feeds. The proportion of the amino acids ( valine, arginine, leucine, isoleucine and glutamic acids) increased in DY feeds compared to the control. Mean final body weight (1.03±0.12 kg) and body weight gain (0.96±0,11 kg) of DY-fed broilers were significantly (p<0.05) higher than (0.90±0.04 kg) and (0.83±0.04 kg) of the control but similar to those of lysine-fed broilers (0.98±0.04 kg) and (0.91±0.04 kg), respectively. The results suggest that dried yeast can be used as a lysine source in broiler feeds.

Science World Journal , 2009,
Abstract: The aim of the study was to investigate the phytochemical components and the antibacterial activities of some powdered herbal medicinal preparations sourced from identified herbal shops and retail outlets in different parts of Kaduna metropolis. Extracts obtained from the herbal preparations were screened for the presence of secondary metabolites using established procedures. Also, antibacterial activities of the extracts were evaluated. Carbohydrates and tannins were identified in 105 (70%) and 101 (67.3%) of the samples respectively. Alkaloids were found in 97 (64.7%); saponins were detected in 91 (60.7%), while anthraquinones, flavonoids and cardiac glycosides were identified in 82 (54.7%), 80 (53.3%) and 60 (40%) of the herbal preparations respectively. All the methanolic extracts had inhibitory activities on the test bacterial isolates at various minimum inhibitory concentrations: 81 (54%) had inhibitory effects on Staphylococcus aureus, 74 (49.3%) on Escherichia coli, 74 (49.3%) on Salmonella typhi and 63 (42%) on Shigella spp. The uses of these products in herbal medicine are justified. However, further works are needed to identify the chemical nature of the active substances as well as their modes of actions on the bacterial cells and their roles in disease curing.

Abstract: A study was conducted to evaluate an herbal methionine replacement product in diets for young broiler chicks. A corn-soybean meal diet that was complete in all respects but methionine was prepared and divided into three aliquots. One was supplemented with 0.30% DL methionine and another was supplemented with the herbal methionine replacement product. Each of these was then blended with the unsupplemented basal diet to provide diets with 0, 0.05, 0.10, 0.15, 0.20, 0.25 and 0.30% of either DL methionine or the herbal methionine replacement product. Each diet was fed to twelve pens of five male broiler type chicks each in electrically heated battery brooders. The diets and tap water were provided for ad libitum feeding from day of hatch to 18 d of age. Analysis of the diets indicated that the methionine activity of the diets with DL methionine was close to expected values but no apparent increase in analyzed methionine activity in diets supplemented with the herbal methionine replacement product. Body weight gain and feed conversion of birds fed the diets with DL methionine were significantly superior to that of birds fed the diets with the herbal methionine replacement product. No significant differences were observed between birds fed the two products for weight of digestive or immune organs when expressed as a percentage of body weight. These data suggest that the herbal methionine replacement product is not suitable for use as a methionine source in diets for young broiler chicks.

Pakistan Journal of Nutrition , 2008,
Abstract: Studies were conducted to chemically characterize and biologically evaluate millet offal as a replacement for maize in the diets of broiler chickens. Two types of millet offal were chemically characterized: the one obtained as a by-product of brewing industry and the other a by-product of pap manufacture. Studies were further carried out to further determine the effects of varying levels of millet offal obtained from the brewing industry on the performance of broiler chickens. The results of the studies indicated that millet offal from the brewery contained 14.60% CP, 4.57% CF, 2.25% EE, 2.90% Ash and 2148.0kcal/kg ME while the one from pap manufacture contained 20.65% CP, 3.12% CF, 3.01% EE, 3.36% Ash and 2506.0kcal/kg ME. The results further indicated final body weight values of 602.02, 605.85, 605.83 and 561.72g/bird for starter chicks (5 weeks old) and 2283.7, 2192.2, 2145.9 and 1904.5g/bird for finisher chickens (9 weeks old). Generally, there was an increase in feed intake as dietary millet offal increased. Feed cost per bird generally decreased when millet offal replaced maize in the diets. Therefore, millet offal can be classified as medium energy and protein sources in poultry diets. Moreover, millet offal can replace up to 50% maize in the diet without any adverse performance of broiler chickens and at reduced cost of feed production.

Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v71i4.722
Abstract: Information on the traditional tick control methods used in Keffa, Illubabor and Wellega Provinces in western Ethiopia was obtained from 86 veterinary clinics and 865 peasant farmers through a questionnaire survey. Latexes of Euphorbia obovalifolia and Ficus brachypoda, juice of crushed leaves of Phytolaca dodecandra and Vernonia amygdalina, fruit juice of Solanum incanum, crushed seeds of Lepidium sativum mixed with fresh cattle faeces, juice of crushed leaves and bark of Calpurnea aurea and commercially available spice of Capsicum spp. mixed with butter, were used by peasant farmers to control ticks. Preliminary in vitro efficacy tests of these plant preparations were performed on engorged female Boophilus decoloratus. Preparations of Capsicum spp., E. obovalifolia, S. incanum and F. brachypoda were found to have 30-100 % killing effects. Subsequently, in vivo treatment trials of these preparations were conducted using indigenous Bos indicus cattle naturally infested with ticks. Results indicate that treatments at the rate of once per day for 5 consecutive days with the latexes of E. obovalifolia and F. brachypoda can reduce tick burdens by up to 70 % on cattle.

Abstract: The antioxidant potentials for fourteen multipurpose traditional herbal preparations sold in South Africa were determined using the DPPH radical scavenging, ferric reducing power and β-carotene-linoleic acid model system, the anti-HIV-1 reverse transcriptase (RT) enzyme inhibitory effects using an ELISA kit and acetylcholinesterase (AChE) enzyme inhibition using the microtitre plate assay. Nine of the herbal mixtures (Umzimba omubi, Umuthi wekukhwehlela ne zilonda, Mvusa ukunzi, Umpatisa inkosi, Imbiza ephuzwato, Vusa umzimba, Supreme one hundred, Sejeso herbal mixture Ingwe? and Ingwe? special muti) exhibited higher antioxidant potentials, while only four (Imbiza ephuzwato, Ingwe? muthi mixture, Sejeso herbal mixture Ingwe? and African potato extractTM) showed potent activity against the RT enzyme. Nine mixtures (Imbiza ephuzwato, Umpatisa inkosi, African potato extractTM, Sejeso herbal mixture Ingwe?, Vusa umzimba; Ingwe? muthi mixture, Ibhubezi?, Lion izifozonke Ingwe? and Ingwe? special muti) showed AChE enzyme inhibitory activity greater than 50%. The observed activity exhibited by some of the herbal mixtures gives some credence to the manufacturers’ claims and goes part of the way towards validating their use against certain conditions such as oxidative stress, HIV/AIDS proliferation and some mental conditions. It is however, desirable to carry out further studies to determine the effects of mixing plant species/parts in one mixture on the antioxidant potency as well as isolating active constituents from the herbal mixtures.

International Journal of Poultry Science , 2006,
Abstract: An experiment was conducted to determine the comparative efficacy of DL-methionine and herbal methionine on performance and carcass characteristics of broiler chickens. Two thousand and four hundred d-old commercial broiler (VenCobb) chicks were purchased and randomly divided into four dietary treatment groups of 600 birds each. Each treatment group was further subdivided into three replicates of 200 broilers per replicate. The treatments groups were control; control plus 10g DL-methionine/kg diet; control plus 10g herbal methionine (Herbomethion , supplied by Indian Research and Supply Co. Ltd.) /kg diet and control plus 15g herbal methionine/kg diet. There were significant effects of dietary treatments on body weight, body weight gain, feed intake and feed conversion ratio at 0 to 41 day. The body weight and body weight gain of the broilers fed the 15g herbal methionine/kg diet were heavier than other treatments. Feed conversion ratio of broiler fed 15g herbal methionine/kg diet was significantly better than that of broilers fed on 10g herbal methionine or DL-methionine/kg diet. Neither DL-methionine nor herbal methionine supplementation had a significant effect on broiler mortality. Plasma protein and enzyme concentration was unaffected by the dietary treatments. Abdominal fat (%) and liver lipid (g/kg) was significantly decreased by the addition of 15g herbal methionine/kg diet. This study demonstrates that herbal methionine can replace DL-methionine very effectively when used at the rate 15g/kg diet of commercial broiler chicken.
