An experiment was carried out in Nicobari fowl to investigate the efficiency of dietary iron supplementation on iron fortification in eggs. Birds were as-signed to each of four dietary treatments in a completely randomized de-sign: T1: Control (commercial layer feed); iron was supplemented in the form of iron- soy proteinate (Fe-SP) chelate @ 200 ppm (T2), 400 ppm (T3) and 600 ppm (T4). Birds were fed ad-libitum as per nutritional specification of BIS (2007). 60 d feeding trial showed that 200 ppm enhanced iron content in egg yolk to 64 μg/g yolk at 15th day of feeding as compared to control (50 μg/g yolk) and improved hatchability (24%). Further fortification beyond 200 ppm (400 & 600 ppm) was not effective. Egg iron content was maximized at 15 days after feeding supplemental Fe. It was concluded that iron enriched egg could be produced on commercial basis to meet the consumers changing need.

Abstract Objectives Although iron fortification/supplementation is recommended for infants (6 to 12 months) and toddlers by pediatrics, the optimal dose is still largely debated. One of controversies centers on whether iron fortification at recommended dose increases the risk of infection. Using a weanling piglet model, we aim to assess the dose of iron fortification on host susceptibility to enterotoxigenic E. coli (ETEC) infection. Methods Thirty-two weanling piglets were randomly assigned to four treatments on PD21, including normal iron diet (250 mg/kg) without ETEC challenge (CON), and Low (125 mg/kg; LOI), normal (COI), or high iron (750 mg/kg; HII) diets with ETEC challenge. On study day 10 (d10), piglets were orally inoculated with 1010 cfu/dose of F18 ETEC once daily for 3 consecutive days. The pathogen colonize in small intestine and cause watery diarrhea in weanling pigs. Piglets were euthanized on d16 for tissue sampling. A 5-scale fecal score were recorded daily. Feces collected on d10, 13 and 16 were plated on blood and MacConkey agars to verify absence or presence of the pathogen. Blood sampled on d0, 10, 13 and 16 were analyzed for hemoglobin, hematocrit, iron and cytokines. Intestinal tissue sections will be stained for iron using Prussian blue and spatial localization of E. coli through fluorescence in situ hybridization. Results The pathogen was absent in feces of all piglets on d10 before inoculation, but was detected at different abundances only in ETEC-inoculated piglets on d13. By d16, only 2 fecal samples from each ETEC-inoculated group were positive for the pathogen, which was accompanied by improved fecal scores. Piglets in LOI suffered more days of diarrhea (fecal score >2) as compared to CON and COI (P < 0.05). Iron content did not affect BW by d10. Nonetheless, piglets in LOI had lower BW (P < 0.05) than those in HII and CON on d16. Hemoglobin was consistently higher in HII than that in COI and LOI. Enteric infection reduced hemoglobin regardless of dietary iron content. Conclusions Our preliminary results showed both iron inadequacy and excess exacerbated ETEC-induced diarrheal illness. However, high iron improved growth during transient ETEC infection in weanling pigs. Funding Sources UC Davis; NIFA.

The significance of the mineral elements in animal nutrition cannot be over emphasized. The presence of mineral elements in animal feed is vital for adequate the metabolic processes. Sixteen (16) crossbred weaned pigs aged eight weeks weighing between 6-7 kg were used in experiment to investigate the effect of feeding varying dietary levels of toasted soybean hull on macro and micro minerals in blood of weaned pigs. The pigs were randomly allotted to four treatments T1, T2, T3 and T4 containing 0%, 5%, 10% and 15% of toasted soybean hull respectively. Water was supplied ad libitum. At the end of feeding trial, two pigs per treatment were selected and blood collected for analysis. Results showed that there were significant (p>0.05) differences in macro minerals. Calcium value ranged from 10.40mg/dL in T1 to11.05mg/dL in T4. Phosphorus ranged from 13.20mg/dL to 17.54mg/dL. Potassium value ranged from 4.65mg/dL to 5.65mg/dL. Magnesium ranged from (3.98mg/dL to 4.80mg/dL). Sodium value ranged from (137.50mg/dL to 143.50mg/dL). Iron, copper and manganese values were significantly (p<0.05) influenced by the dietary treatments with the values ranging from 57.50 – 48.00mg/kg, 42.34 – 31.87mg/kg and 10.95 – 8.85mg/kg respectively. For zinc, the value ranged from 1.04mg/kg to 1.30mg/kg. Based on the findings of this study, it can be concluded that toasted soybean hull could be fed to weaned pigs up to 15% inclusion level without any adverse effects on the macro and micro minerals composition of weaned pigs.     On ne saurait trop insister sur l'importance des éléments minéraux dans la nutrition animale. La présence d'éléments minéraux dans l'alimentation animale est essentielle pour un traitement métabolique adéquat. Seize (16) porcs sevrés croisés âgés de huit semaines pesant entre 6 et 7 kg ont été utilisés dans l'expérience pour étudier l'effet de l'alimentation de différents niveaux alimentaires de coque de soja grillé sur les macro et micro minéraux dans le sang des porcs sevrés. Les porcs ont été attribués au hasard à quatre traitements T1, T2, T3 et T4 contenant respectivement 0 %, 5 %, 10 % et 15 % de la coque de soja grillée. L'eau a été fournie ad libitum. À la fin de l'essai d'alimentation, deux porcs par traitement ont été sélectionnés et le sang prélevé pour analyse. Les résultats ont montré qu'il y avait des différences significatives (p>0,05) dans les minéraux macro. La valeur de calcium s'est étendue de 10.40mg/dL dans T1 à11.05mg/dL dans T4. Le phosphore tégrait de 13,20 mg/dl à 17,54 mg/dl. La valeur de potassium s'est étendue de 4.65mg/dL à 5.65mg/dL. Le magnésium tégrait de (3,98 mg/dL à 4,80 mg/dL). La valeur en sodium varierait de (137,50 mg/dL à 143,50 mg/dL). Les valeurs de fer, de cuivre et de manganèse ont étésignificativement influencées (p<0,05) par les traitements diététiques dont les valeurs vont de 57,50 – 48,00 mg/kg, 42,34 – 31,87 mg/kg et 10,95 – 8,85 mg/kg respectivement. Pour le zinc, la valeur varierait de 1,04 mg/kg à 1,30 mg/kg. D'après les résultats de cette étude, on peut conclure que la coque de soja grillée pourrait être nourrie à des porcs sevrés jusqu'à un niveau d'inclusion de 15 % sans effets négatifs sur la composition macro et micro-minérale des porcs sevrés.

This study was undertaken to evaluate the effect of supplements of siris (Albizia lebbeck) flowers and leaves on Merino wethers fed Mitchell grass hay (Astrebla spp.). Three groups, each of 6 sheep, were fed the following diets: hammermilled Mitchell grass hay ad libitum (M); M + 181 g DM/day of siris flowers (MF), and M + 216 g DM/day of siris leaves (ML). The experiment, conducted over 17 days, measured feed intake and digestibility, nitrogen (N) retention, and plasma glucose and urea concentrations. The total DM intakes by MF and ML sheep were significantly (P<0.01) higher than those in M sheep. As a result of the supplement of siris flowers, the digestibility of the MF diet was highest (P<0.01). Sheep fed the M diet showed negative N retention, while MF and ML sheep showed positive N retention. The increased (P<0.01) N retention in the MF and ML sheep was associated with increased (P<0.01) urinary N excretion. The improved nutritional state of MF and ML sheep was associated with increases in plasma glucose and urea concentrations. Environmental temperature, which reached a mean daily maximum of 31.3�C, did not interact with the dietary treatments.

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

Haematological and serum biochemical parameters are indicators of physiological, nutritional and pathological status of animals. Investigation of these parameters provide information for diagnostic purposes. The study was conducted to determine the influence of feeding graded levels of yam peel meal (YPM) as a replacement for maize on haematology; blood chemistry was evaluated in rabbits. Thirty- six (New Zealand white X Chinchilla) were randomly assigned to four dietary treatments in a completely randomized design with nine rabbits per treatment. The rabbits were fed diets containing 0, 12.5, 25 and 37.5% of Yam peel meal (YPM) as a replacement for maize, designated as T1, T2, T3 and T4, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were randomly selected for hematological and serum biochemical analysis. All the haematological and serum biochemical indices except AST were affected (P<0.05) by dietary inclusion of YPM. Although most of the parameters investigated were affected by rabbits fed test ingredient, the values fell within the normal literature reference values for rabbits. It can therefore be concluded that up to 37.5% inclusion level of YPM can be fed to growing rabbits without deleterious effects on health status.

Iron deficiency reaches epidemic proportions in infants, particularly those of low socioeconomic status.1 In an attempt to decrease the frequency of this deficiency, iron fortification of infant cereals and cow's milk formulas has been advocated.2 Although the prevention of iron deficiency is a valid nutritional goal, concern has recently been voiced about possible detrimental effects of iron supplementation.3,1 This concern has been based on studies indicating an association between hyperferremia and serious infection,3,6 and also by denionstrations that the bacteriostatic properties of serum and milk can be abolished by the addition of iron.7,8 These findings have been extrapolated into suggestions that the iron supplementation of cow's milk formulas might predispose the infants consuming them to an increased risk of bacterial infection and even that ironcontaining formulas might be contraindicated.4

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first- and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second- or third-cut grass silage (550 g kg-1 dry matter), rolled barley (435 g kg-1 dry matter) and a mineral-vitamin mixture (15 g kg-1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first- or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first- and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.

The experiment which lasted for seventy (70) days was conducted to determine the effects of various dietary levels of sunflower seed meal (SSM) on the performance of growing rabbits. Thirty- two (32) indigenous breeds of rabbits obtained from small-scale producers were used in study. They were individually weighed and randomly assigned to the four (4) dietary treatments, in which 0,10, 20 and 30% of the groundnut cake was replaced by SSM, respectively. The diets contained 2391.76, 2387.44, 2383.12 and 2378.80 Kcal ME/kg for diets 1,2,3 and 4, respectively. The crude protein (CP) was approximately 14.0% for the four (4) experimental diets. The diets, in mash form were fed to the rabbits ad libitum. There was no significant difference (P > 0.05) amongst the treatments in all the parameters examined. However, he incorporation of SSM resulted in a considerable decrease in feed cost with increasing levels of SSM. Thc. results of this Study therefore suggest that 30% or more of the GNC could be replaced by SSM in the diets of growing rabbits without deleterious effect on performance.
