Effects Of Using Hemp Hearts As A Feed Additive In Broiler Chicks, Brian Parr, Cheyenne Hooks, Mallorie Snider, Huichang Chae, Tony Brannon

Journal of Agricultural Hemp Research

In this experiment, hemp hearts of differing percentages were fed to broiler chicks for 49 days. The experiment, which was initiated to identify the potential of hemp hearts as a feed source, consisted of four experimental groups and one control group. Each experimental group received a diet containing: 10%, 20%, 30% and 40% hemp hearts; the control group did not contain hemp hearts, but contained soybean meal. As a result, broilers fed a diet containing 20% hemp hearts gained the most weight, t(16) = 2.12, p < 0.05 and feed conversion was also the lowest t(18) = 2.10, p < 0.01. These results indicate the feed efficiency of broilers using 20% hemp hearts was the lowest numerically, but the most efficient qualitatively. The diets consisting of higher percentages of hemp hearts demonstrate a need for additional supplementation.


Effects Of Phytase On Broilers Performance And Body Status Of Phosphorus, جمال ابو عمر, ربيع صبحه Aug 2020

Effects Of Phytase On Broilers Performance And Body Status Of Phosphorus, جمال ابو عمر, ربيع صبحه

Hebron University Research Journal-A (Natural Sciences) - (مجلة جامعة الخليل للبحوث- أ (العلوم الطبيعيه

his experiment was conducted to investigate the effect of microbial phytase supplementation on broilers performance, nutrient digestibility, carcass cuts and body status of Ca and P. A total of 200 day-old Cobb-500 chicks were used in the experiment. Birds were partitioned into five experimental groups of 40 birds each treatment was composed of 4 replicates with 10 birds in each. The control group was fed a commercial starter and finisher diet. The second treatment group was fed a phosphorus deficient diet, while the third, fourth and fifth treatments groups were fed a phosphorus deficient diets plus the microbial phytase. Phytase …

A broiler chicken study was conducted for 42 D to evaluate their responses to 3 commercially available microbial phytases. Growth performance, nutrient digestibility, and bone mineralization at days 21 and 42 posthatching were used as parameters of evaluation. The study was a randomized complete block design with 12 treatments, 8 replicate pens, and 25 birds per pen. Treatments included a positive control (PC), a negative control (NC) with crude protein (CP), nonphytate phosphorus (P), and calcium (Ca) reduced by 18, 1.5, and 1.8 g/kg, respectively; the NC + 4 levels of phytase A (250, 500, 750, 1,000 FTU/kg), 3 levels …


Distillers Dried Grains With Solubles: Determination Of Metabolizable Energy Values Using Regression-Based Assays And Their Correlation With Chemical Composition, Kenia Mitre Jul 2020

Distillers Dried Grains With Solubles: Determination Of Metabolizable Energy Values Using Regression-Based Assays And Their Correlation With Chemical Composition, Kenia Mitre

Graduate Theses and Dissertations

The inherent variability and lack of standardization of in vivo assays to determine the metabolizable energy (ME) of DDGS has led to inconsistent values and limited its potential to use in broiler diets. Therefore, two experiments were conducted to characterize the content of nitrogen-corrected ME (MEn) in 11 DDGS sources obtained from various ethanol plants using a regression-based broiler assay and to attempt to develop equations to predict MEn based on its chemical composition. In experiment 1, the objectives were to determine the influence of inclusion level and feed intake on the resulting ME and MEn values of a single …


Effect Of Dietary Spirulina Platensis On Stress Levels And Growth Of Female Broiler Chickens, Victoria Tarkington May 2020

Effect Of Dietary Spirulina Platensis On Stress Levels And Growth Of Female Broiler Chickens, Victoria Tarkington

Animal Science Undergraduate Honors Theses

This study measured the effects of dietary Spirulina platensis supplementation on heterophil to lymphocyte ratio, footpad lesions, and growth performance parameters. One hundred and eighty Ross 708 broiler females were randomly divided evenly into fifteen pens with three dietary treatments for a total of five replications per treatment (twelve birds per replicate) for five weeks. The different treatments were a control diet of 20% crude protein, a diet of 17% crude protein, and a diet of 17% crude protein with 10% S. platensis added to the feed. Body weight, feed intake, and mortality rate was not significantly different between treatments …


Effects Of Selenium And Zinc Supplementation On Cadmium Toxicity In Broilers, Evangelos Zoidis, Athanasios C. Pappas, Ali Al-Waeli, Constantinos A. Georgiou, George P. Danezis, Nikos Demiris, George Zervas, Konstantinos Fegeros Jan 2020

Turkish Journal of Veterinary & Animal Sciences

Cadmium (Cd) is a toxic metal regarded as an environmental pollutant. The potential ameliorative effect of simultaneous addition of Se and Zn to broilers against Cd toxicity was examined. A total of 180 as-hatched broilers were used. There were 4 replicate pens of 3 dietary treatments: T1, T2, and T3. In T1, Se, Cd, and Zn were added to a basal diet at 0.3, 0, and 100 ppm, in T2 at 0.3, 50, and 150 ppm, and in T3 at 0.5, 50, and 150 ppm respectively. Selenium, Cd, Ca, Co, Cu, Fe, Li, Mg, Mn, Sb, As, Cr, Pb, Mo, …
