Effect of Varying Inclusion Levels of Fossil Shell Flour on Growth Performance, Water Intake, Digestibility and N Retention in Dohne-Merino Wethers

This study was carried out to determine the effect of varying levels of Fossil shell flour (FSF) supplementation on growth performance, water intake, digestibility and N retention in Dohne Merino sheep pursuant to establishing the optimum inclusion rate of this supplement in Dohne Merino diets. Sixteen Dohne-Merino wethers (18 ± 1.5 kg body weight) were used in a complete randomized design with four animals per treatment. Sheep were fed a basal diet without FSF addition (control, T1), or with the addition of FSF (2%, T2), (4%, T3) or (6%, T4) of the diet for 105 days. Treatment 3 (4% FSF) has the highest values of dry matter intake, total weight gain, N retention and for most of the apparent digestibility nutrients (CP, EE and Ash) compared to treatment T1, T2 and T4(p < 0.05). The urinary and fecal N excretion also significantly decreased in the FSF treated diets compared to the control (p < 0.05). Water intake values were highest in control and were significantly (p < 0.05) different from those in treatments 2 and 4, but not to treatment 3. It is concluded that 4% inclusion rate of FSF will give the best improvement on growth performance, diet digestibility and N retention of Dohne-Merino sheep. Also, the addition of FSF in the diets of sheep is a safe natural additive that can help to reduce environmental pollution by reducing fecal and urinary N excretion.

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.

The aim of this study was to determine the calcium requirements of broiler chickens in starter phase with the addition of phytase enzyme. This experiment used 1,200 broiler chickens (mixed sex) for 21 days rearing period in a closed house. The basal diets was corn and soybean meal which contained 0.097% Ca and 0.123% P-av. The treatments consisted of 6 diets treatment: P1 (basal diet with the addition of 0.42% non-phytate phosphorus (NPP), and then P2 to P6 were basal diet with the addition of 0.22% NPP and 1,000 FTU/kg phytase and the addition of calcium (Ca) at different levels: 0.82% (P2); 0.74% (P3); 0.66% (P4); 0.58% (P5) and 0.50% (P6). The growth performance, feed efficiency, and bone mineralization parameters were studied using Oneway ANOVA in a Completely Randomized Design. Duncan's new Multiple Ranges Test was used to separate means with significant differences. Results showed that 0.90% Ca supplementation without phytase and the reduction levels of Ca from 0.82% to 0.50% increased the amount of feed consumed by birds in all growth phases (P<0.05). The addition of phytase had beneficial effects on increasing body weight (P<0.05) and average of body weight gain (P<0.05), and decreased the value of FCR in 11 - 21 days and 1 - 21 days. The addition of phytase increased protein and energy consumption, followed by increased in the value of PER and EER (P<0.05). When phytase was added in the diets, reduction levels of Ca in the diets up to 0.50% did not give any adverse effect on the tibia bone ash. It can be concluded that feeding with phytase can sustain growth performance, feed efficiency, and bone mineralization.

High energy diet is related to high feed cost. Thus, it is essential to reduce energy diet but still support the good performance of birds. The utilization of low cost- feed ingredients combined with enzymes are the alternative way to do. The objective of this study was to investigate the effects of multy-enzyme supplementation on growth performance of broilers fed low energy basal diets containing rice bran. Experiment 1. The apparent metabolizable energy (AME) assay of yellow corn and rice bran. A total of 48 broilers were randomly distributed to 12 cages (4 birds/cage). A maize-soybean meal basal diet (mash form) was formulated and two assay diets were then developed by substituting rice bran (raw 250 g kg-1, w/w) and maize (500 g kg-1, w/w) of the basal diet. Total excreta collection method was used. The results showed that the AME value of rice bran was significantly lower (2032 kcal/kg DM) and 3112 Kcal/kg DM. Experiment II. The experiment was designed using a completely randomized design with four treatments and six replications. A total of 160 DOC (unsex) were randomly distributed to 16 pens (10 birds/pen). The experimental diets were iso-nitrogenous and iso-energetics. The results show that dietary treatments significantly affected (P0.05) FCR and mortality of broilers. Broilers fed P2, P3 and P4 diets had higher (P0.05). In conclusion, 1) the supplementation of enzymes in low energy diets containing rice bran improved BWG and FI but not FCR and mortality. 2) Birds fed rice bran-containing-diets supplemented with enzymes produced similar growth performance.

The study aimed to evaluate growth performance of grower pigs fed fermented liquid potato hash with or without exogenous enzyme. Diets containing either 200 (LFLPH) g/kg potato hash (enzyme treated or not); 400 (HFLPH) g/kg potato hash (enzyme treated or not) or no fermented potato hash (control) were formulated to provide 14 MJ/kg digestible energy (DE), 180 g/kg crude protein (CP) and 11.6 g/kg lysine. Dietary treatments were control (no FLPH), enzyme treated LFPHE and HFLPHE, and untreated LFLPH and HFLPH. The exogenous enzyme was added in treated diets to provide minimum of 560-840 TXU/TDU xylanase per kg feed, at an inclusion rate of 100 g/tonne. Diets were mixed with water at 1:2 ration and fermented for 8 hours at 25 °C room temperature before being fed to pigs. Back-slopping fermentation approach was followed to prepare diets. Twelve pigs (25±2.3 kg) per diet that were individually housed were fed ad-lib for eight weeks. Pigs were allocated to diets in complete randomized design. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured. The enzyme treated FLPH diets had higher (P < 0.05) CP, lower (P > 0.05) NDF and ADF concentrations compared to untreated FLPH diets. The LFPHE diet had higher (P < 0.001) final weight, ADG and lower (P < 0.001) ADFI and FCR compared to LFPH, HLFPH and HLFPHE. It was concluded that LFPHE diet may be an alternative feed source for growing pigs as indicated by higher gain and lower intake compared to LFLPH, HFLPH and HFLPHE.

Experimental Trials

Introduction: Various types of feed additives have been evaluated under commercial conditions and in experimental trials with the aim to achieve improvements on growth performance and the best economic return. Herbs, including Sesame indicum leaves, spices and various plant extracts/essential oils can be used as alternatives to replace antibiotic growth promoters as they are rich in phytochemicals (active compounds) that can be used to stimulate growth and health of the animals. The uses of all these herbs should be studied in relation to the blood and serum indices of the animals in order to determine their harmful level of consuming them by the animals. Therefore, the aim of the study is to determine the effect of different dietary inclusion levels of Sesame indicum leaves on haematology and serum parameters of broiler chickens at both starter and finisher phases. Methods: A total of one hundred and fifty 1-day old, unsexed (Marshal) broiler chicks were randomly divided into five experimental groups at rate of 30 birds per group. Each group was further subdivided into three replicates at the rate of ten chicks per replicate in a Complete Randomized Design. A maize-soybean basal diet served as control while the Sesame indicum leaves was added to the basal diets at level (0g, 10g, 20g, 30g and 40g/kg) resulting in five formulae, respectively. At the end of the 4th and 8th weeks respectively, six birds were randomly selected from each of the replicate and blood samples were collected from the jugular vein of birds for haematology and serum. Results: The results indicated that all the haematology and serum parameters were significantly (p < 0.05) affected by the different inclusion levels of S. indicum leaves but the value obtained were within the recommended range while birds fed with the diet containing 40g/kg of S. indicum leaves had the highest values. Conclusion: Inclusion of S. indicum leaves in the diets appear not to have detrimental effect on the haematology and serum parameters of the experimental birds. The study recommended that 40g/kg inclusion level be adopted as it improved growth performance and general well-being of broiler chickens.

Abstract To evaluate the effects of probiotics on performance and gut health of Escherichia coli-challenged weaned pigs, a total of 28 weaned pigs (initial BW = 8.25 kg) were housed individually in pens and fed 4 experimental diets for 21 d in a completely randomized design. The 4 diets were corn-soybean meal-based basal diet without or with 0.25% antibiotics (neomycin + oxytetracycline), 0.05% Bacillus subtilis DSM 32540, or 0.05% Bacillus pumilus DSM 32539. All pigs were orally challenged with K88 strain of E. coli on d 3. Feed intake and BW data, and blood samples were collected on d 3, 7, 14, and 21. Fecal scores were recorded daily. On d 21, pigs were sacrificed to determine gastrointestinal histomorphology, pH and organ weights. Supplementation of the basal diet with antibiotics or B. pumilus did not affect the overall (d 0 to 21) ADG and G:F. The B. subtilis supplementation did not affect the overall ADG, but tended to increase (P < 0.1) the overall G:F by 15%. Fecal score was unaffected by dietary treatment. Supplementation of the basal diet with either probiotic, but not antibiotics increased (P < 0.05) jejunal villous height and reduced (P < 0.05) cecal digesta pH. Supplementation with B. pumilus tended to increase (P < 0.1) colon weight relative to BW; however, antibiotics or B. subtilis supplementation did not affect colon weight. The addition of B. subtilis to basal diet tended to increase (P < 0.1) serum immunoglobulin A concentration on d 21 of the study; however, such effect was not observed with the addition of antibiotics or B. pumilus. In conclusion, dietary B. subtilis improved G:F and jejunal villous height and reduced cecal digesta pH, indicating that dietary supplementation with B. subtilis at 0.05% could improve growth performance and gut health of weaned pigs.

This study aimed to determine the effects of replacing corn with hydroponically sprouted barley (HSB) in Holstein heifer feed on growth performance and blood metabolites. For this purpose, the barley was prepared with hydroponic sprouting under optimized conditions, and its chemical composition was analyzed on a dry matter (DM) basis. A total of 30 Holstein heifers that were 7 months old with an average body weight of 212.60 ± 55.00 kg were used in a completely randomized design comprising 10 repetitions and three groups over a period of 11 months. Dietary treatments included control (CON), basal diet (corn meal-based diets), and trail diets, in which 10% and 30% HSB gradually replaced corn meal. The growth performance and biochemical indices were analyzed every month. Results showed that the HSB diet increased chemical compositions compared with the control diets on a DM basis. In addition, diets with up to 30% HSB did not show any negative effects on the growth performance (body weight, height at withers, and height at rump) or selected blood metabolites of heifers compared with the CON diet. In conclusion, the use of HSB instead of corn meal did not lead to any adverse effects on growth performance or biochemical indices; therefore, HSB can be used as an alternative dietary source for raising Holstein heifers.
