The effects of dietary copper supplementation on serum copper level and performance were studied in a 174-day feeding experiment involving 16 female West African dwarf goats level and using depletion - repletion approach, The results obtained showed a significantly lower  (P<0.05) but traces of serum copper after depletion combined with pre depletion (1.70 to 1.90 Ug/dl serum) and after 42 days of dietary repletion (1.28 to 2.50 Ug/dl serum). The best  responses in terms of growth rate (0.114 kg/day) highest dry matter intake (1.43 Ugg feed DM) were induced by 240.68 Ug Cug DM of feed. The goats managed maintenance requirement for copper was 5.033 UgCuw0.75. while the dietary copper supplementation requirement was 240.68 Ug They had free access to salt licks and water.

The study evaluated the effects of level of feed offer on dry matter intake (DMI) , digestibility, the parts of plants selected and on the growth rate of West African dwarf (WAD) goats without resulting in toxicity. Seven different levels of feed offer ranging from 40g/kg0.75/day to 130Wkg0.75/day in increments of 15g/kg0.75) were fed to two groups of goats. The first group was fed 100% Gliricidia while the while the second was fed 50% Gliricidia and 50% Leucaena diet (50/50). The level of feed offer had significant effect on the DIM and digestible DMI (DDMI) of the goat (P < 0.01). The Leucaena intake in a 50/50 diet was always higher than the Gliricidia intake except at 55g1kg0.75 offer level. The level of feed offer had significant effects on the parts of plants selected (P < 0.01.) and on the growth rate. The leaf intake was statistically higher than the stem intake (P < 0.01). All the goats on 40g/kg0.75 and 55g/kg0.75 on a 100% Gliricidia diet lost weight while only those on 40g/kg0.75 lost weight on a 50/50 diet. There was no significant difference in the growth rate of goats on feed offer levels of 70g to 130g/kg0.75 (P > 0.05). The study indicate that goats performance was higher on a mixed browse diet than on Gliricidia alone. Goats performed best at 100g/kg0.75 offer level.

<b><i>Introduction:</i></b> The association of serum copper with polycystic ovarian syndrome (PCOS) has been studied for years, but no definite conclusion is drawn. Therefore, we conducted a meta-analysis to investigate serum copper concentrations in PCOS subjects compared with healthy controls. <b><i>Methods:</i></b> Electronic search was performed in PubMed, Google Scholar, and Scopus up to June 30, 2020, without any restriction. Standardized mean differences (SMDs) with corresponding 95% CIs in serum copper levels were employed with random-effects model. <i>I</i><sup>2</sup> was applied to evaluate heterogeneity among studies. <b><i>Results:</i></b> Nine studies, measuring plasma copper levels in 1,168 PCOS patients and 1,106 controls, were included. Pooled effect size suggested serum copper level was significantly higher in women with PCOS (SMD = 0.51 μg/mL, 95% CI = [0.30, 0.72], <i>p</i> &#x3c; 0.0001). The overall heterogeneity was not connected with subgroups of the country, but derived from the opposite result of 1 study. <b><i>Conclusion:</i></b> Our research generally indicated circulating copper level in PCOS sufferers was significantly higher than normal controls. Large-scale studies are still needed to elucidate the clear relation between copper status and etiology of PCOS.

The study was designed to explore serum copper as a risk factor for coronary artery disease (CAD). In this case-control study 30 healthy controls and 60 diagnosed cases of acute myocardial infarction (AMI) were enrolled. Serum copper concentration and serum lipid profile were measured in all study subjects. Serum copper level was significantly higher in AMI as compared to controls. The concentrations of serum TC, TG, LDL-C level were found to be significantly higher in cases as compared to controls. The concentration serum HDL-C was found to be significantly lower in cases as compared to controls. CAD leads to raised serum copper level and it has positive correlation with TC, TG and LDL-C but negative correlation with HDL-C in males.Keywords: Coronary artery disease; serum copper; acute myocardial infarction; total cholesterol; triglyceride; low density lipoprotein cholesterol.

AbstractThe present study compares estimates of caecotrophes production from urinary purine derivatives (PD) excretion with that from preventing caecotrophy by using a neck collar. A total of 64 New Zealand growing male rabbits were used to study the effect of diet composition on caecotrophes production. Diets were formulated using two sources of structural carbohydrates (fibre): alfalfa hay (AH) and sugar-beet pulp (SBP), mixed at two constant proportions, (0·75: 0·25) AH diets and (0·25: 0·75) SBP diets. Both diets included either barley or maize grain at two fibre: grain ratios (F/G, 80: 20 and 45: 55). Diets were given ad libitum. Growth rate, dry matter intake and digestibility were not modified by the grain source, although high F/G diets resulted in a lower growth rate (19·8 v. 26·4 g/day; P < 0·001). Between fibre sources, dry-matter intake and growth were higher in AH than in SBP diets (122·5 and 25·6 v. 101·6 and 20·4 g/day, respectively, P < 0·001 and P < 0·01). Rabbits given high F/G ratio and AH diets excreted more caecotrophes than those given low F/G ratio and SBP diets (19·5 and 20·9 v. 16·3 and 14·85 g/day, respectively). Microbial-N recycling through the caecotrophy process was higher when considering data from PD excretion (1·33 g/d) than when estimated by preventing caecotrophy (0·72 g/day).

ABSTRACTFive different straws consisting of two varieties of winter barley, two varieties of spring barley and one variety of winter wheat were chosen due to differences in degradation characteristics determined by using nylon bags incubated in the rumen of cattle and describing the straw using the equation: p = a + b (1 – e–ct). To increase variation in degradability, batches of the same straws were also treated with anhydrous ammonia in a sealed oven.The straws were subsequently offered ad libitum to groups of steers given a daily supplement of 1·5 kg concentrate and untreated straws were supplemented with urea. The dry-matter intake (DMI) of the straws varied from 3·4 to 5·7 kg/day, the digestible DMI from 1·4 to 3·5 kg/day and growth rate from 106 to 608 g/day.By using multiple regression of a, b, c from the exponential equations characterizing degradability of the straw, the correlation coefficients with DMI, digestible DMI and growth rate were 0·88, 0·96 and 0·95 respectively.

Legume–grass forage was ensiled two seasons in 25-ton polyvinyl-encased stacks at dry matter (D.M.) levels of 22 to 37% or stored as field-cured hay. The polyvinyl sleeve coverings provided initial gas-tight conditions. High losses occurred in the high D.M. (32 to 37%) silage during the feeding-out period. Silage quality, as indicated by volatile fatty acid ratios, proximate principles, and digestibility coefficients, was not significantly influenced by D.M. content. When cows were fed the lower D.M. (22 to 29%) silages and hay, forage intake was inversely related to its dry matter content. Intake of high D.M. silage appeared abnormally low. Milk yields appeared to be more consistently influenced by small variations in grain intake than forage dry matter intake through both trials. Milk yields from silages were greater than from hay per unit of D.M. intake. Moisture content of forage had no significant effect on milk composition as indicated by percentage of butterfat, solids-not-fat, or protein.
