Fifty-four barrows (27.5 ± 0.5 kg) were given ad libitum for 7 wk one of 18 diets prepared from field corn inoculated with different strains of Fusarium graminearum, naturally contaminated corn and wheat, pure deoxynivalenol (DON), and clean corn. The effect of 4.7 mg pure DON kg−1 feed was not significantly different from that of the control, whereas pigs on several diets at a similar DON level had significantly lower feed intake and weight gain values. There was no correlation between DON concentration in the diets, amount ingested and pig performance. Key words: Vomitoxin, deoxynivalenol, pigs, inoculated corn, Fusarium, mycotoxins

n eight week study was conducted to assess the performance, carcass characteristics and haematological indices of broiler chickens provided water from different sources. One hundred and fifty day - old broiler chicks (Arbor acre) were randomly allocated to five treatment groups (rain, stream, pipe borne water, well and borehole water respectively) in a completely randomized experimental design. The borehole water was obtained from a residential building, about 500 m to the experimental site (Federal College of Agriculture (FECA), Akure, Nigeria). Rainwater was harvested when it rained and was stored in plastic containers before it was used. It was not stored for more than three days before use. Stream water was obtained from a stream that flowed close to the students' residential area of FECA. It is sometimes drunk and is typical of streams that flow in a typical village community. Well water was obtained from a well sunk within the premises of the FECA. It was a well from where people fetched water for domestic use and was provided to the birds without prior treatment. Pipe borne water was obtained from the Water Corporation Mains that supplies FECA and Ijapo Estate, Akure. Results from the experiment revealed that there were no significant (P>0.05) differences among the treatments in terms of water intake, feed intake, weight gain, feed conversion ratio, carcass characteristics, relative weight of some organs, muscle dimensions and haematological parameters. Pipe borne water had the highest numerical values (P>0.05) for most of the performance and carcass characteristic indices measured, such as daily water intake (181.53±14.6), cumulative water intake (8.90±.71), daily feed intake (106.27±4.15), cumulative feed intake (5.21±0.20), daily weight gain (38.53±2.38), total weight gain (1.89±0.12), final weight gain (1.98±0.12), percent dressed weight (97.11±0.16%), percent eviscerated weight (81.86±3.26%), relative weights of drumstick (99.37±5.43g/kg), wings (89.10±9.69g/kg), chest (170.08±6.59g/kg) and back (159.40±18.90g/kg live weight) respectively. Water from different sources (rain, well, pipe borne water, borehole and stream) had no significant (P>0.05) effect on the performance indices, considered in the study for broiler chickens. This implies that the aforementioned water sources can be used to raise broiler chickens provided such water is free from any contaminants that could impair the health of the birds.

In this study, the effect of three different sources of maggot meals was conducted to evaluate the performance and slaughter characteristics of broiler chickens. Five diets were formulated to include Diet 1 (control) which contained 3.5 % fish meal, while Diets 2, 3 and 4 contained 3.5% maggot meal from broiler droppings (BMM),maggot meal from layers droppings (LMM) and maggot meal from rabbit faeces (RMM) respectively. Eighty (80) dayold unsexed Marshall Broilers were randomly allotted to four dietary treatments in a completely randomized design (CRD). Thedietary treatments had 20 birds each with two (2) replicates. Data were generated on proximate analysis and performance indices including feed intake and weight gain, slaughter characteristics and mortality rate. They were subjected to analysis of variance (ANOVA) and means significantly different were separated using Duncan's Multiple Range Test (DMRT) at 5% probability level. Results from proximate analysis showed that maggots from layer droppings had the highest crude protein and ether extract. Results on performance indices showed that birds fed on diet 3 (layer maggot meal) had significantly (P<0.05) best performance than others as regards feed intake. Layer maggot meal (LMM) in this study enhanced bestproductive performance compared to those from broiler and rabbit maggot.Birds fed layer maggot meal had the best (1.85) feed conversion ratio. They also had the best body weight gain (2501g) and feed intake (4627g). In conclusion, layer maggot meal is recommended as analternative animal protein source to expensive fish meal.

Six groups each of five barrows and five gilts were offered ad libitum one of six pelleted diets containing 68% wheat. A pellet binder was added (1.5%) to all diets. There were three clean wheat diets, one unsupplemented, one supplemented with a binding agent (Antitox Vana) and another with Fusarium graminearum inoculated corn; also, three vomitoxin-contaminated wheat diets, one unsupplemented, one supplemented with Antitox Vana and another with ammonium carbonate. Vomitoxin content was negligible in the clean wheat (control) diet, and was about 5 mg/kg in the three contaminated diets and 14 mg/kg in the inoculated corn diet. Pigs weighed 35 kg initially and a necropsy was conducted on each after 5 wk on experiment. Feed consumption was reduced 15–17% with the contaminated wheat diets, and approximately 50% with the inoculated corn diet from which effect the pigs seemed never to recover to the level of those fed the contaminated wheat diets. Discoloration of the stomach mucosa, and epithelial thickening of the esophageal area occurred in more pigs fed the contaminated wheat diets than those fed the clean wheat (control) diet, and a more marked response was evoked by the inoculated corn diet. The addition of the binding agent or the ammonium carbonate did not appear in this experiment to alleviate any of these effects.

A total of seventy-two weaner rabbits of eight weeks of age were used to assess the effects of replacing groundnut cake (GNC) with blood vegetable waste meal (BVWM) in the diets of rabbits. The BVWM was fed to replace dietary GNC at 0, 15, 30, and 45%, with GNC being 15% in the control diet. The four experimental diets were fed ad libitum for a period of eight weeks. BVWM was analyzed to contain a crude protein value of 62.35%. There were comparable feed intake values by rabbits on all the diets although the rabbits in the higher replacement levels of BVWM tended to have consumed more of the feed. There were significant increases (P<0.05) in body weight gain by rabbits as the BVWM level increased in the diet. Similarly, the feed to gain ratio improved and nitrogen digestibility increased (P<0.05) with higher levels of BVWM in the diet. This study shows that rabbits can tolerate the 45% BVWM replacement of groundnut cake effectively.

Potential Interactions

The performance of growing pigs fed 2 mg kg−1 of one of several Fusarium graminearum metabolites (sambucinol, 15-acetyldeoxynivalenol, 3-acetyldeoxynivalenol, culmorin, dihydroxycalonectrin) with and without 6 mg kg−1 deoxynivalenol (DON) was examined in three preliminary studies. The only significant effects (P < 0.05) were seen in feed consumption, weight gain and feed efficiency due to the presence of DON in the diet. In addition, the appearance and degree of folding of the esophageal portion of the stomach were also different between pigs fed the DON-free and DON-contaminated diets, though the degree of significance varied between trials. Some small differences were seen in growth and feed consumption for certain metabolites, notably sambucinol and culmorin, with and without DON, but they were not significant (P > 0.05). The data indicate that, at the dietary concentrations used, the fungal metabolites tested in combination with DON do not interact with DON in growing pigs to any marked degree.

SUMMARYIn an experiment with group-fed cattle from 6 months of age to slaughter at 480 kg live weight two levels of feed intake: 1, ad libitum, 2, 85% of ad libitum amount, were combined with two ratios of concentrate to hay: a, 70: 30; b, 30: 70. In two further treatments, 3a and 3b, the cattle were fed diets a or b at 70% of ad libitum from 6 to 10 months and ad libitum thereafter.Daily gain during the first 124 days of the experiment was (in grams) 1293, 983, 1097, 846, 992 and 756, and from the 125th day to slaughter 735, 600, 796, 579, 830 and 714, for treatments la, lb, 2a, 2b, 3a and 3b, respectively. The decline in rate of gain from the first period to the second was inversely related to the level of feed intake and to the percentage of concentrates in the ration in the first period.Daily carcass gain was 582, 393, 532, 350, 531 and 368 g for treatments la, lb, 2a, 2b, 3a and 3b, respectively.The treatments that were switched over from 70% of ad libitum feed intake in the first period to 100% in the second (3a and 3b), exhibited considerable compensatory growth in the second period, but this was not sufficient to be of economic advantage.The overall ME requirement per kg of live-weight gain was inversely related to rate of gain. Of the six treatments, 2a (85% of ad libitum, 70% concentrate) was the most efficient (19·8 Mcal/kg live-weight gain).Animals on the 100% level of feed intake throughout the experiment (treatments la, lb) were significantly fatter than those on the other treatments.

Whole canola/pea (WCP, 1:1 wt/wt) or whole canola/canola meal (WCC, 3:1 wt/wt) were heat-processed using a commercial pellet mill prior to incorporation in broiler starter (0–20 d) and finisher diets (20–40 d). The pelleted blends readily disintegrated in the preparation of the mash diets. Body weight gain of broilers (0–40 d) fed WCP (0, 10, 20, or 30%) or WCC (0, 5, 10, or 15%) declined linearly with level of dietary inclusion (P < 0.01). Feed intake declined curvilinearly (P < 0.01) with both blends, with lower intake most apparent at the higher inclusion levels. Feed/gain increased for broilers fed WCP or WCC (P < 0.01). Overall broiler mortality declined incrementally with inclusion of WCP (P < 0.07) or WCC (P < 0.03) in the diet. Although there was no distinct limitation on the dietary inclusion levels of either blend, the low feed intake with broilers fed 15% WCC indicated that its level should not exceed 10% of the diet.

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

This study was carried out to evaluate the effect of 45 minutes Boiled Mucuna Seed Meal (BMSM) on the growth performance and nutrient digestibility of broiler finisher chicks. In a four-week feeding trial, three hundred and fifteen (315),4-week old broiler chicks were  randomly allocated to five experimental treatment diets in a completely randomized design (CRD). Each treatment was replicated thrice having twenty-one (21) birds per pen. Boiled Mucuna seed meal was prepared and fed in graded levels of 0.0% (control diet), 10.0%, 20.0%, 30.0%, and 40.0%BMSM. Feed and water were given to the birds ad libitum. The parameters measured and calculated include final weight, weight gain, feed intake, feed to gain ratio and feed cost per kilogram gain. Digestibility of dry matter, crude protein; crude fibre, ash, nitrogen free extract and ether extract were also determined. The data collected were subjected to analysis of variance (ANOVA). The results showed that dietary levels of inclusion of BMSM had significant (P<0.05) effect on these parameters. The final weight, the weight gain and feed intake of the birds fed 0.0%, 10.0% and 20.0%BMSM were statistically (P>0.05) similar and significantly (P<0.05) higher than those of other treatments. Cost of feed per birds and feed cost per kilogram gain were lower for all BMSB diets.Digestibility of nutrients was better for the birds fed the control,10.0 and 20.0%BMSM based diets. It was concluded that inclusion of BMSM in the diets of broiler finisher chicks up to20% has no deleterious effect on growth performance and nutrient digestibility of the birds.     Cette étude a été réalisée pour évaluer l'effet de 45 minutes de farine de graines de Mucuna (le 'BMSM') bouillie sur la performance de croissance et la digestibilité des éléments nutritifs des poussins finisseurs de poulet à griller. Dans un teste d'alimentation de quatre semaines, trois cent quinze (315), poussins de poulet de griller de 4 semaines ont été aléatoirement attribués à cinq régimes expérimentaux de traitement dans une conception complètement randomisée (le 'CRD'). Chaque traitement a été reproduit trois fois avec vingt et un (21) oiseaux par enclos. Le repas bouilli de graine de Mucuna a été préparé et alimenté dans les niveaux classés de 0.0% (régime de contrôle), 10.0%, 20.0%, 30.0%, et 40.0%BMSM. L'alimentation et l'eau ont été données aux oiseaux ad libitum. Les paramètres mesurés et calculés comprennent le poids final, le gain de poids, la prise d'aliments pour animaux, le rapport alimentation/gain et le coût des aliments pour animaux par gain kilogramme. La digestibilité de la matière sèche, protéines brutes; des fibres brutes, des cendres, de l'extrait sans azote et de l'extrait d'éther ont également été déterminés. Les données recueillies ont fait l'objet d'une analyse de la variance (ANOVA). Les résultats ont montré que les niveaux diététiques d'inclusion de 'BMSM' ont eu un effet significatif (P<0.05) sur ces paramètres. Le poids final, le gain de poids et la prise d'alimentation des oiseaux nourris 0.0%, 10.0% et 20.0%BMSM étaient statistiquement (P>0.05) semblables et significativement (P<0.05) plus élevés que ceux des autres traitements. Le coût de l'alimentation animale par oiseau et le coût de l'alimentation par kilogramme étaient inférieurs pour tous les régimes BMSB. La digestibilité des éléments nutritifs était meilleure pour les oiseaux alimentés le contrôle,10.0 et 20.0% BMSM régimes à base. Il a été conclu que l'inclusion du BMSM dans l'alimentation des poussins finisseurs de poulet de gril jusqu'à 20 % n'a aucun effet délétère sur la performance de croissance et la digestibilité des oiseaux en matière d'éléments nutritifs.

Foram avaliados os parâmetros zootécnicos de frangos de corte alimentados com dietas suplementadas com diferentes fontes e níveis de selênio (Se), criados sob diferentes condições de temperatura. Foram utilizados 720 pintainhos, Cobb-500, em um delineamento inteiramente ao acaso em esquema fatorial 3 x 2 x 2 (3 temperaturas ambiente: termoneutra, fria e quente; 2 níveis de suplementação de Se: nível A e B; e 2 fontes de Se: orgânica e inorgânica), com 4 repetições de 15 aves. Os níveis A e B de Se na ração inicial (1 a 21 dias) e de crescimento (22 a 42 dias) foram 0,15 e 0,30 mg/kg e 0,20 e 0,40 mg/kg, respectivamente. Selenometionina foi usada como fonte de Se orgânico e selenito de sódio, inorgânico. Os frangos criados em condições de estresse por calor apresentaram uma redução no consumo de ração e ganho de peso. Não houve influência da suplementação das diferentes fontes ou níveis de Se no ganho de peso, consumo de ração ou conversão alimentar. Os resultados são indicativos de que a suplementação de Se não melhora o desempenho de frangos de corte criados em condições de temperatura adversa. Evaluation of different sources and selenium levels for broilers at different temperatures Abstract This study evaluated the effect of selenium (Se) diet supplementation on productive parameters of broiler chickens raised under different temperatures, in a complete randomized design with 3 x 2 x 2 factorial schedule (3 environmental temperatures: cold, neutral and hot; 2 levels and two Se sources) with 4 repetitions of 15 birds. The levels of Se in rations for initial and growth phases were: 0.15 and 0.30 mg/kg; and 0.20 and 0.40 mg/kg, respectively. The organic and inorganic sources of selenium were selenomethionine and sodium selenite, respectively. There were a reducing in broiler feed intake and weight gain of the broilers housed in the hot temperature. Selenium levels or sources did not affect the weight gain, feed intake or feed conversion. It was concluded that Se supplementation did no affect the broiler performance, housed under adverse environmental temperature.
