Mountain Roosters
<p>Men have a peculiar way of teaching young boys how to be men. The peculiarity of it is in those men’s relationship with their emotions. Especially in Appalachia, boys are encouraged to “be a man” and not to “cry like a girl.” They are encouraged to suppress their emotions, to solve problems with …

Temporal profile of gonadal steroids in populations of roosters divergently selected for mating frequency
… profile in genetically selected populations of roosters differing in sexual activity. Plasma levels of androstenedione (AE), dihydrotestosterone (DHT), testosterone (T), total androgens (Total A) and estradiol-17<sub>β</sub> (E₂) were measured at 1, 56, 112 and 168 days of age by …

Avian Infectious Bronchitis Virus: A Tropism for the Rooster Reproductive Tract and Effects on Reproductive Performance
… free amino acid levels are altered in vaccinated roosters when compared to non-vaccinated roosters. Fourth, differentially expressed seminal plasma proteins were identified in vaccinated roosters when compared to non-vaccinated roosters. These data provide further evidence that the proper function …

Reproductive Soundness and Egg Quality in Chickens Selected for Low and High Antibody Response
… from that selection. Forty-five hens and 25 roosters from each antibody line were used. In hens, commencement and intensity of lay, and egg quality, were analyzed; in both sexes, length of fertility was considered. Hens and roosters were mated to an intercross line to avoid confounding …

Determination of relative metabolizable energy values for fats and oils via the slope-ratio precision-fed rooster assay
… both conventional (CONV) and cecectomized (CEC) roosters. Lipids were fed in ground corn diets to CONV roosters in Experiments 2 through 6. Palomys®, stearidonic (SDA) soybean (soy) oil, three commercial animal/vegetable (A/V) blends (A/V blend 1, 2 and 3) and corn oil from distillers dried …

Nutritional Evaluation Of New Reduced-Oligosaccharide Soybean Meal And Canola Meals Produced From New Varieties Of Canola Seeds For Poultry
… energy (TMEn) assay with conventional roosters. The second experiment was a precision-fed cecectomized rooster assay that was conducted to determine TMEn and amino acid digestibility. The third experiment was a standardized ileal amino acid digestibility (SIAAD) assay, in which broiler …

Methodology to evaluate the nutritive value of feedstuffs for poultry and swine
… using 24 adult Single Comb White Leghorn roosters. After 24 hours of fasting, six roosters were force-fed 25 g of each of these feedstuffs. Six roosters were fasted for another 48-hour period and served as negative controls. Excreta were collected for two consecutive 24-hour periods. …

Further evaluation of a slope-ratio precision-fed rooster assay for relative bioavailable energy values for fats and oils
… bioavailable energy values. In Experiment 1, roosters were precision-fed 0, 5, or 10% of five different fats as part of a ground corn diet totaling 30 g of diet per rooster. Refined soy oil (the reference oil), poultry fat, crude soy oil, crude corn oil, and palm oil 1 were all evaluated. In …

Evaluation of the nutritional values of seven insect meals for inclusion in poultry diets
… rooster assays to determine TMEn in conventional roosters or amino acid digestibility in cecectomized roosters. The roosters were precision-fed 25 to 30 g of one of seven insect meals which included three different black soldier fly larvae meals (BSFL), one partially-defatted BSFL, one cricket …

Nutritional evaluation of novel ethanol co-products for poultry
… assays with conventional and cecectomized roosters were conducted to determine TMEn and amino acid digestibility, respectively. The TMEn of Glutenol™ was determined to be 3256 kcal/kg DM. Standardized digestibility values for Lys, Met, Cys, Thr and Val were 80.1%, 90.4%, 74.1%, 81.1% and …

Nutritional evaluation of canola meal produced from a new variety of canola seeds in broiler chickens and laying hens
… determine the values of MEn using conventional roosters and ileal digestible amino acid values using cecectomized roosters. The first experiment evaluated a conventional canola meal (Conv CM) in broiler chicken diets from 2 to 37 days of age. Treatments were replicated eight times using five …

Effect of particle size on nutritional value of soybean meal for poultry
… of the SBMs were determined using conventional roosters while the standardized amino acid digestibility was determined using cecectomized roosters. In both experiments, six single comb white-leghorn roosters were tube fed 30 g of one of the seven SBM samples. There were no significant …

Evaluation of the precision-fed rooster assay for detecting effects of exogenous carbohydrases and adaptation diet on true metabolizable energy and cecal microbial ecology, short-chain fatty acid profile, and enzyme activity
… In both experiments, Single Comb White Leghorn roosters were fasted for 26 h and then crop intubated with either 25 or 30 g of the test diets. Excreta were collected quantitatively for 48 h after feeding. In Experiment 1, all carbohydrase combinations either numerically or significantly (P < …

Localization of P450 aromatase in sperm and estrogen receptors in the epididymal region of the rooster
… levels of ER mRNA in the epididymal region of roosters was suppressed in the presence of reduced serum concentrations of testosterone. These data clearly demonstrate that rooster germ cells and epididymal sperm are sites for the synthesis of estrogen and the epididymal region of the rooster is …

The Effect of Various Feed Additives on Growth Performance, Nutrient Utilization, and Cecal Microbial Populations in Poultry
… (TOS) were fed to adult roosters at a concentration of 4 or 8 g/kg. Data showed that the true digestibility of amino acids (AA) and metabolizable energy (MEn) were not negatively impacted. Each oligosaccharide was then evaluated at 4 or 8 g/kg in day-old chicks. …

Evaluation of in vitro methods to estimate digestibility of amino acids in the rumen undegraded protein fraction of feedstuffs
… for AA and crop-intubated to cecectomized roosters. Results of the rooster experiments indicate that AA digestibility differs from RUP-AA for DDGS samples, and RUP-AA digestibility differs within samples. For the modified three-step procedure, digestibility of all AA in all feedstuffs was …

Branched -Chain Amino Acid Nutrition of Grow-Finish Pigs and Young Chicks
… RBC product was determined in both cecectomized roosters and ileal-cannulated pigs and found to be 97%. Broken-line analysis of dose titrations of Ile (0.38 to 0.58% true digestible Ile) suggested a true digestible Ile requirement of 0.50% for growing pigs. Minimal plasma urea-nitrogen levels in …

Evaluation of red and white sorghum as alternative carbohydrate sources and the effects of extrusion in monogastric nutrition through the determination of macronutrient digestibility, fecal microbiota, digestible and metabolizable energy content
… (P < 0.05) the TMEn of RSH in conventional roosters and WSH in cecectomized roosters. The standardized amino acid digestibility of all grains was greater than 75% except lysine for raw WSH and extruded RSH. Extrusion increased the digestibility of arginine, histidine, lysine, methionine, …

Amino acid digestibility of various feedstuffs using different methods
… The PFR involves tube-feeding cecectomized adult roosters and excreta are then quantitatively collected for amino acids. For the SID, 3-week-old broiler chicks are ad libitum fed a semi-purified diet with the test ingredient added as a sole source of protein for a period of several days. The …
