Abstract There is a consistent demand for grass-fed livestock products in the domestic market. Alternative grazing strategies should be considered to sustain the year-round production of grass-fed products that meet consumer demand and support animal health and performance. The objective of this study was to evaluate the effect of annual forages on the growth and parasite resilience of growing lambs. We hypothesized that lambs grazing annual forages would increase their body weight at a greater rate when compared to lambs grazing stockpiled pasture. A total of 54, 60-day-old lambs (24 kg ± 4.9 kg) were stratified by weight, sex, and randomly assigned to one of three grazing treatments: 1) oats (O); 2) turnips (T); and 3) stockpiled tall fescue pasture (F). Lamb body weight and indices of parasitism were measured every 14 days. Data were analyzed using PROC MIXED in SAS. There was a treatment × day effect for body weight such that T lambs were heavier on days 42 and 56 than O and F lambs (P < 0.03). Furthermore, there was a treatment × day effect for average daily gain (ADG) whereas T lambs had a greater ADG on days 28 and 42 than O and F lambs (P < 0.0001). In addition, on day 42, F lambs had a greater ADG when compared to O lambs (P < 0.003). For the indices of parasitism, T lambs demonstrated lesser total plasma protein concentration on days 28 and 42 when compared with O lambs (P < 0.05). Forage type plays a critical role in lamb resilience to gastrointestinal parasites and body weight gain whereas T lambs showed a greater liveweight gain. However, T lambs also demonstrated lesser concentrations of total plasma protein when compared to O lambs. Under these conditions, annual forages adequately sustained the growth of fall grazing lambs.

The study aimed to evaluate the effect of SOYXYL as one of the dietary protected protein supplement product in the rations on the reproduction performance of Simmental bulls. Twelve 5 years-old Simmental bulls were allotted to 4 treatment groups with 3 replications in each, i.e.: T0= control ration (elephant grass + 5 kg/head/day commercial concentrate), T1= control ration + 150 g protected protein supplement SOYXYL (3% of concentrate), T2 = control ration + 300 g SOYXYL (6% of concentrate) and T3= control ration + 450 g SOYXYL (9% of concentrate). The experiment lasted for 90 days. At the end of the experiment, semen and blood were collected and body weight gain was measured. The variables measured included sperm motility, sperm concentration, blood protein, blood urea and the concentration of testosterone. Results showed that SOYXYL supplementation, particularly at the levels of 3 and 6%, increased the total plasma protein of bulls. SOYXYL supplementation at 3% from concentrate resulted in increased plasma urea concentration. Feeding SOYXYL, particularly at the levels of 6 and 9%, increased the average daily gain of bulls as compared to control. Feeding 3% SOYXYL increased, but at the levels of 6 and 9% decreased the concentration of sperm of bulls. The concentration of testosterone was higher in the bulls received 3 and 6% SOYXYL in the rations. Dietary supplementation of SOYXYL increased the sperm motility of Simmental bulls. In conclusion, dietary supplementation of SOYXYL at the level of 3% increased plasma protein, testosterone, and sperm concentrations as well as sperm motility. However, supplementation of SOYXYL at 6 and 9% from rations decreased the concentrations of sperm and testosterone.

Dialysis-induced hypovolemia occurs because the rate of extracorporeal ultrafiltration exceeds the rate of refilling of the blood compartment. The purpose of this study was to evaluate a method for calculating circulating blood volume (BV) during hemodialysis (HD) from changes in hematocrit (Hct) shortly (2 to 10 min) before and after ultrafiltration (UF) was abruptly stopped. Hct was monitored continuously during 93 HD treatment sessions in 16 patients by an optical technique and at selected times by centrifugation of blood samples. Total plasma protein and albumin concentrations were also measured at selected times. Continuously monitored Hct correlated with Hct determined by centrifugation (R = 0.89, N = 579). Relative changes in BV determined by continuously monitored Hct were not different from those determined by total plasma protein concentration (P = 0.05; N = 273). Calculated BV at the start of dialysis (4.1 +/- 1.3 L) was not different (P = 0.18, N = 12) from that derived anthropometrically from the patient's dry weight (4.6 +/- 0.8 L), and calculated BV when UF was stopped was 3.2 +/- 0.5 L (46 +/- 7 ml/kg body wt). These latter estimates of BV are consistent with those determined previously by dilution techniques in HD patients. It was concluded that (1) relative changes in BV assessed by continuously monitored Hct were unbiased and (2) BV can be determined noninvasively during HD by continuously monitoring Hct and temporarily stopping UF.

Plasma volume by the dye (T-1824) method, hematocrit, hemoglobin concentration and plasma specific gravity were determined, and from them total blood and erythrocyte volumes and plasma protein concentration were derived in hypophysectomized female rats fed standard and enriched diets. The effects of insulin, growth hormone and prolactin were also studied. Hypophysectomy decreased the plasma volume and established a lower, stable plasma volume/body weight ratio which was not influenced significantly by diet or hormones. The erythrocyte volume/body weight ratio markedly reduced after hypophysectomy, was readily increased by the enriched diet, especially in younger animals. Insulin injections did not alter the blood picture or increase the body weight. Growth hormone increased both plasma and erythrocyte volumes proportionally to the elevation in body weight and also increased the total plasma protein. Prolactin, possibly contaminated with growth hormone as noted by the tibia test, acted similarly to growth hormone but to a lesser extent.

Abstract Gastrointestinal nematodes and other pathogens pose a major problem for goat production by reducing animal performance and welfare. Plants such as Acacia Senegal are useful as dietary sources for natural prophylaxis. Gum Arabica (GA) from A. Sengal has antimicrobial, anti-inflammatory properties that need to be explored in goats. The objective of this study was to investigate the possible immunomodulatory effect of a water extract of GA in goat blood. Clinically healthy Boer and Spanish goats from the NCA&T Small ruminant unit were used. Goats were assigned randomly to two groups of ten (n = 20). Goats of one group were drenched daily with 10 mL of GA (treatment I) extract for 6 weeks. The second (control) group of goats received sterile water (treatment II). Blood was collected from the jugular vein in tubes containing acid-citrate-dextrose anticoagulant. Plasma was separated and the concentration of total protein was determined using Pierce BCA kit (Thermo Scientific Pierce, Rockford, IL). The white blood cell differential count was assessed on Wrights smeared stains. Data were analyzed using PROC GLM in SAS 9.4 (P < 0.05). Treatment with GA modulated total plasma protein concentration and the differential white blood cell counts. Treatment increased total plasma protein concentration and % lymphocytes, it decreased % neutrophils. Immunomodulation by GA may be advantageous in promoting health and wellness in goats. Further studies on the mechanism of action are warranted.

Lemna sp. is known to have several bioactive compounds and polysaccharide macromolecules that can function as immunomodulators to affect non-specific immune responses to increase the body's resistance to pathogens. This study aims to determine the potential of catfish eye extract as an immunostimulant by observing non-specific tilapia immune parameters. The extraction method used was 96% ethanol maceration for 2 days with a ratio of 1: 4. The experimental design used a Completely Randomized Design with 5 treatments (doses 0.2, 0.4, 0.6 mg/kg, control + and control -) and 3 replications. The non-specific parameters of immunity observed included total plasma protein (Bradford method), superoxide dismutase and lysozyme activity. The data obtained will be analyzed using ANOVA, if there is a significant difference, it will be further tested with Duncan Multiple. Range Test (DMRT). The results showed that the highest total plasma protein was found in treatment C (giving an extract of 0.3 mg/kg body weight) with an average total plasma protein after 12 days of maintenance of 4.99 g / dL. The extract dose of 0.3 mg/body weight showed a rapid decrease in SOD and increase Lysozyme activity.

ABSTRACT The effect of graded levels of dietary aflatoxin on the assessment of genetic variability of body weight and gain and plasma protein response was tested utilizing the Athens-Canadian randombred population of chickens. Dietary aflatoxin was administered at levels of either 0, 1.25, 2.50 or 5.0 µg/g of diet ad libitum from 7 to 21 days of age to progeny from 58 sire families. Twenty-one-day body weights, gain and plasma protein concentration were used to assess the variation in response.—The administration of increasing levels of aflatoxin resulted in a dose-related decrease of gains and plasma protein concentrations. Plasma protein concentrations were significantly higher among males than females within the control group; however, this difference was reversed as the severity of the aflatoxin challenge increased. Heritability estimates for all responses increased as the level of aflatoxin administered increased. This change was most notable for total plasma protein concentration. Phenotypic correlations for plasma protein concentration and growth measurements tended to diminish with increasing levels of aflatoxin. A similar trend was noted for the genetic correlations; however, a moderate correlation between growth responses and plasma protein response was detected in the 5.0-µg/g aflatoxin treatment group. Genetic correlations were calculated for the same characters between the different levels of aflatoxin. Regardless of which aflatoxin challenges were compared, a very high genetic correlation for 21-day body weight and 7- to 21-day gain was estimated. This variation in growth potential in the toxic environment paralleled that observed in the control environment but at a lower plane. Genetic correlations for plasma protein response across aflatoxin levels diminished as the difference between the levels of aflatoxin administered increased. Plasma protein concentration in the control environment was positively correlated with plasma protein response in groups fed a low level of aflatoxin, but negatively correlated when an aflatoxin challenge of 2.5 µg/g or more was given, suggesting that selection for aflatoxin resistance using plasma protein response as a selection criterion should be made under an aflatoxin stress environment.
