The Rice straw has several nutritional weaknesses, namely its high silica and lignin content, and its low level of protein, minerals and vitamins, so the impact on digestibility is also low. Aim of present study was to evaluating nutritional efficacy of rice straw after fermentation with Trichoderma viride. The study was conducted by using complete random design (CRD). There were three different treatments with four replicates for each treatment. Fermented rice straws were treated with varying concentrations of Trichoderma viride inoculum as follows; 0.5% (P1), 1% (P2), and 1.5% (P3). Fermented rice straw's nutrients, including dry ingredients, organic material, crude fiber, crude protein, dry matter digestibility coefficients, and organic matter digestibility coefficients were measured in this study. P3 (1.5% of Trichoderma viride) treatment performed a proper nutrient, with 80.02% dry ingredients, 80.03% organic materials, 31.68% crude fiber, 5.72% protein, 38.46% dry matter digestibility coefficient, and 61.05% organic matter digestibility coefficient. In conclusion, using 1.5% Trichoderma viride to improve the quality of rice straw, as stimulator of fermentation process can be efficient in ruminant or non-ruminant nutrition.

This study aimed at evaluating the fermention levels of pearl millet [Pennisetum Glaucum (L.) R. Br] stovers silage during storage based on pH evolution. A completely randomized experimental design in a 6×2×2 factorial scheme with three replications for each treatment was used to evaluate three factors (6 cultivars, 2 different cutting stages, and with or without salt addition to the cultivars). The silages were prepared in plastic bags and stored for 60 days at room temperature. The results revealed that the pH values of the treatments were significantly (P < 0.05) higher on the first day than in the other periods and a rapid drop in pH, with significant differences (P < 0.05), to levels below 4 was obtained on the third day of storage for the majority of local Sadoré and Siaka Millet silages (Niger). Four types of pH evolution were recorded and the variation was statistical significant among cultivars. Also, analysis of the relationships between pH, chemical composition parameters and In Vitro Digestibiliy of Organic Matter (IVDOM) showed that increasing pH values were associated with increasing Dry Matter content of stovers before silage (DM_BE), Dry Matter content of silages (DM_S), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL) values and decreasing Crude Protein (CP), Metabolizable Energy (ME), IVOMD, and Ash values. However, the pH values obtained for all silages showed that all the millet stovers used were suitable for silage. At the maturity stage, it is thus possible to use the grain for human consumption and to ensile the stovers for animal feed. This study also shows that monitoring the pH in the silo makes it possible to evaluate the quality of the fermentations to avoid losses on the farms.

The study aimed to investigate the effects of supplementing fermented chicken litter on feed consumption, nutrient digestibility (dry matter/DM, organic matter/OM, crude fiber/CF, extract ether/EE, crude protein/CP), total digestible nutrients (TDN), and average daily gain (ADG) in sheep. A completely randomized design with 4 treatments and 3 replications, namely T0 = concentrate without the addition of fermented litter, T1 = 90% concentrate + 10% fermented litter, T2 = 80% concentrate + 20% fermented litter, T3 = 70% concentrate + 30% fermented litter and T4 = 60% concentrate + 40% fermented litter was used. The parameters studied were dry matter digestibility (DMD), organic matter digestibility (OMD), extract ether digestibility (EED), crude fiber digestibility (CFD), crude protein digestibility (CPD), TDN, feed consumption and average daily gain. The results revealed that sheep fed different levels of fermented litter did not affect OMD, DMD, EED, CPD, CFD, TDN, dry matter consumption, and average daily gain (ADG). It was concluded that fermented chicken litter can be incorporated in sheep diet, without considerable negative effects.

Phase-feeding is the feeding of several diets for a relatively short period of time to specifically meet an animal’s nutrient requirements. The study evaluated the effect of different phase feeding methods on growth and carcass characteristics of broiler chickens. A total of 120-day-old chicks of the FIDAN strain were assigned to four dietary treatments of 30 birds each, 15 birds per replicate. Birds were fed at different phases: Phase 1 were fed broiler starter diet alone for 8 weeks; Phase 2 birds were fed starter diet from 0-4 weeks and 1st finisher diet from 5-8 weeks. Phase 3 birds were fed starter diet from 0-3 weeks, 1st finisher diet from 4-6 weeks and 2nd finisher diet from 6-8 weeks. Phase 4 birds were fed starter diet from 0-2 weeks, 1st finisher diet from 2-4 weeks, 2nd finisher diet from 4-6 weeks and 3rd finisher diet from 6-8 weeks of age. Result no significant differences (p>0.05) between the groups in body weight gain (2.91–2.47 kg/bird) and feed conversion ratio (2.03–2.34). Total feed intake was highest in phase 1 (6.70 kg/bird) followed by phase 2 birds (6.41 kg). Dressed weight in Phase 1 was significantly (p<0.05) higher than others, followed by Phase 2. Dressing percentage did not differ significantly (p>0.05) between the groups. Feed cost between treatments was however significantly (p<0.05) different, Phase 1 diet being costliest. Phase-feeding using phase 4 regime elicited reduced dietary cost without compromising optimal performance of the birds.

The aim of this research is to examine how raw and cooked onions affect some antioxidant enzymes and some tissues in female rabbits. Twenty-four female albino rabbits weighing (1-1.5 Kg), (5-6 months age), non-pregnant, were used for the experiment, and they were divided into three groups for a duration of 28 days. A 20 g/kg raw onion and same amount of cooked onion were added to the second and third groups’ diets respectively for comparison of results with control groups without any addition of onion. Results showed that diets supplemented with raw and cooked onion significantly increased the superoxide dismutase (SOD) activity. The cooked onion group showed normal and no pathological changes in liver, kidney, and heart tissues, while liver tissues of both control and raw onion groups suffered extreme congestion in the central veins of the liver lobules and in kidney tissues of only control rabbits, developed hemorrhagic foci was observed. In the control and raw onion groups, the heart tissue showed the development of hemorrhagic foci and necrosis in the heart muscle fibers. In conclusion, both raw and cooked onions boosted the activity of SOD enzyme, but the cooked onions showed to be more effective than raw at protecting liver, kidney, and heart tissues against cell necrosis caused by oxidative processes.

The objective of the study was to investigate performance and carcass quality of Pekin, local, and cross-breed ducks raised under different feeding (varied in protein and fiber levels). A total of 180 male ducks aged 14 days, consisting of 60 Pekin ducks, 60 local ducks (Mojosari), and 60 cross-breed (Mojosari + Alabio) ducks were used in the study. Each type of duck was randomly divided into 36 units of cages, each of which was filled with 5 ducks. The data obtained from the study were analyzed according to a completely randomized design with 2×3 factorial pattern. Initial body weight of local ducks at 14 days was significantly (P<0.01) lower than that of Pekin and cross-breed ducks, while, Pekin ducks were higher than the other two types of ducks. On the other hand, feed consumption was significantly (P<0.01) influenced by the type of diet and breed. While carcass percentage was significantly (P<0.01) influenced by breed and diet types. The percentage of Pekin duck carcasses that received diet A (low protein and fiber) was significantly different (P<0.05) from cross-breed ducks, in comparison to local ducks. In conclusion the feed conversion rate and final body weight for diet A showed better results than diet B (high protein and high fiber) on the Pekin duck. Meanwhile, the carcass characteristics like abdominal fat of diet B (for pekin, local duck, and cross breed) were better than diet A (for Pekin and local duck). It’s suggested to use Pekin ducks with low protein and low fiber diet to get the better performance, in compared with local ducks which needs high protein and high fiber content in diet.

In recent years, global aquaculture production has increased, leading to an increase in fish waste. These wastes, which in many cases are disposed directly without trying to take advantage of them, are a major environmental and economic problem that may affect the sustainability of the fishing and aquaculture industry. Therefore, their use seems necessary to reduce pollution and make the aquatic industry more efficient. Most of well-known technologies for using fish waste are not economically attractive due to the need for high initial investment. But an easy and inexpensive way to use these wastes is to convert them into silage. Fish silage is a product of good nutritional quality included in animal diets as part of the feed. Fish silage is a liquid product made from whole fish or parts of it to which lactic acid-producing acids, enzymes or bacteria are added, and the liquefaction of the material indicates the action of enzymes present in the fish. Therefore, the purpose of this review is to investigate the use of aquatic waste for preparing silage and the possibility of using it in animal nutrition.

This study was conducted to evaluate the effect of polyherbal (phytogenic) formulation (PHF: containing Acacia nilotica and Curcuma longa) on performance parameters, liver histopathology and prevention of fatty liver in broilers. 700 day-old chicks were randomly distributed to seven groups (10 replicates / group; 10 birds each), namely positive control (T1) fed with basal diet + choline chloride (CCL) 60% (1000g), negative control (T2) fed with high energy (5% increment), low protein (24% reduction), high cholesterol (2% increment) diet, T3 (T2 + PHF; 1000g-full cycle), T4 (T2 + PHF; 2000g-full cycle), T5 (T2 + CCL 60% (1000g-full cycle)), T6 (T5 + PHF; 1000g-grower and finisher stage), T7 (T5 + PHF; 2000g-finisher stage). Average daily gain (ADG; g), average daily feed intake (ADFI; g) and feed conversion ratio (FCR) were calculated at 1-14 days, 15-28 days, 29-42 days, and 1-42 days. Serum triglycerides analysis, gross and histopathological observations of liver morphology were performed for the samples of control and experimental groups on day 42. The performance parameters; ADG, ADFI, FCR, and liveability were found to be improved in all the groups as compared to the negative control group. However, better performance was observed in PHF (2000g) top-up group (during the finisher stage) as compared to the negative control group. Serum triglyceride levels were increased non-significantly as compared to the negative control indicating that more fat is mobilized from liver to serum. In addition, PHF supplementation at 2000g during the finisher phase had restored the liver tissue architecture as well as improved the liver score when compared to the negative control group. It is concluded that PHF (2000g/ton) during the finisher stage can be used as a top-up to improve the performance parameters as well as to prevent the fatty liver condition in broiler chickens.

The comparative modulating effects of synthetic and natural source of ascorbic acid (AA) were investigated on transporting pullet birds in the hot-dry season of humid tropics. Ninety-six 16 weeks Isa-brown pullets were randomly allotted in a completely randomized design into four treatments of oral vitamin supplementation 5 days before transportation i.e; T1 (ordinary water), T2 (synthetic vitamin), T3 (30% citrus-sweet orange), T4 (50% citrus-sweet orange). Birds were crated and transported for 3 hrs covering 135km at 45km/hr. Meteorological values were monitored during the journey and no mortality was recorded. The results revealed that treatments had a significant effect (p < 0.05) on measured physiological parameters [body temperature (BTC), rectal temperature (RTC), respiratory rate (RR) and panting rate (PR)], hematological parameters and measured serum biochemical parameters as compared to the control group (T1). The treatments group of orange at different inclusion ratios (T3 and T4) compared well with pullet birds on oral supplementation of synthetic vitamin (T2) and were significantly different (p < 0.05) from birds on control water treatment (T1). Birds on control (T1) had the highest values for all measured physiological parameters which were significantly different from other groups (p<0.05). Birds in the control treatment (T1) were more stressed as compared to other treatment groups, indicated by increased hematological and serum biochemical parameters except for a decrease in hemoglobin (Hb) as compared to other treatments. It can be deduced from this study that the oral supplementation of natural source of ascorbic acid (Citrus sinensis) and synthetic vitamin supplement helps to ameliorate the effect of transportation stress. Citrus sinensis extract can be a suitable alternative that is readily available for farmers and stakeholders.

This study was conducted to evaluate the effects of different inclusion levels of water hyacinth leaf meal fermented with Aspergillus niger on feed utilization efficiency and growth performance of Nile tilapia (Oreochromis Niloticus L.). Fermented water hyacinth leaf (FWHL) at 0, 10, 20 and 30% inclusion levels were incorporated into four isonitrogenous (35% CP), and isoenergetic (18 KJ g-1 g) test diets. The fishes were stocked in 80 liters aquarium units, in a closed, recirculating indoor system. The diets were fed to triplicate groups of fish fingerlings (1.6 g average body weight) twice a day, at 6% of body weight/day, for three months. The study demonstrated that Nile tilapia fed FWHL at levels 30% had a significant negative impact (P<0.05) on weight gain, specific growth rate, feed utilization efficiency, and whole body composition. But, there were no significant changes between diets supplemented with 10% and 20% FWHL when compared with the control group. Therefore, supplementation of fermented water hyacinth leaf meal to diets of Nile tilapia is recommended up to 20% because it is cheaper than fish meal and corn.
