Watermelon rind is one of the several unwanted by-products generated by restaurants, fruit juice producers and food industries in Nigeria that can be gotten rid of by using it as an energy source in broiler production. The growth performance and apparent nutrient digestibility of broilers fed diets containing varying inclusion levels of dried watermelon rind (DWMR) in replacement for wheat offal as source of energy and fibre at starter phase was evaluated. The dried watermelon rind was prepared by sun-drying fresh watermelon for three days and oven-dried at 50 ºC for 2 hours. The birds were randomly allocated to five (5) treatments (T1 – T5), each treatment had three replicates with ten (10) birds per replicate. The birds were fed varied levels of DWMR at 0 %, 25 %, 50 %, 75 % and 100 % in replacement of wheat offal to obtain five diets. Feed and water were provided ad-libitum throughout the 28 days study duration. Body weight, Body weight gain, Feed intake, Feed conversion ratio and apparent nutrient digestibility were measured. The results obtained on the growth performance shows no significant (P>0.05) difference of the growth parameters across treatments. However, there was significant (P<0.05) difference in the digestibility of Crude fibre, Ether extract, Ash, Nitrogen free extract and Total digestible nutrient across treatments. There was no obvious variation in dry matter and crude protein digestibility. The result of the total digestible nutrient was significantly (P<0.05) higher in T2 (92.90 %) than the T1 (84.99 %) which was the control diet. The crude fibre digestibility recorded in T2 (63.48%) and T1 (61.09 %) is higher than T5 (43.00 %), the ether extract digestibility of T1 (96.42 %) is higher than the other groups with the lowest in T4 (95.25 %). There was depress ash digestibility in T5 (68.30 %), lower than the other groups with the highest in T1 (82.59 %). The study therefore concluded that farmers can replace wheat offal with 25 % watermelon rind in broiler starter diet without any deleterious effect in the growth performance and nutrient digestibility.     La croûte de pastèque est l'un des nombreux sous-produits indésirables produits par les restaurants, les producteurs de jus de fruits et les industries alimentaires au Nigéria qui peuvent être débarrassés en l'utilisant comme source d'énergie dans la production de poulets à griller. La performance de croissance et la digestibilité apparente des éléments nutritifs des poulets de grillage nourris selon des régimes alimentaires contenant différents niveaux d'inclusion de la croûte de pastèque séchée (DWMR) en remplacement des aals de blé comme source d'énergie et de fibres à la phase de démarrage ont été évaluées. La croûte de pastèque séchée a été préparée par pastèque fraîche séchée pendant trois jours et séchée au four à 50ºC pendant 2 heures. Les oiseaux ont été attribués au hasard à cinq (5) traitements (T1 - T5), chaque traitement avait trois répliques avec dix (10) oiseaux par réplique. Les oiseaux ont été nourris à des niveaux variés de DWMR à 0 %, 25 %, 50 %, 75 % et 100 % en remplacement des aals de blé pour obtenir cinq régimes alimentaires. L'alimentation et l'eau ont été fournies ad-libitum tout au long de la durée de l'étude de 28 jours. Le poids corporel, le gain de poids corporel, l'apport alimentaire, le rapport de conversion des aliments pour animaux et la digestibilité apparente des nutriments ont été mesurés. Les résultats obtenus sur la performance de croissance ne montrent aucune différence significative (P>0.05) des paramètres de croissance entre les traitements. Cependant, il y avait une différence significative (P<0.05) dans la digestibilité des fibres brutes, extrait d'éther, cendres, extrait sans azote et nutriment digestible total entre les traitements. Il n'y avait aucune variation évidente dans la matière sèche et la digestibilité brute de protéine. Le résultat du nutriment digestible total a été significativement (P<0.05) plus élevé en T2 (92.90 %) que le T1 (84.99%) qui était le régime de contrôle. La digestibilité des fibres brutes enregistrée en T2 (63.48%) et T1 (61.09 %) est plus élevé que T5 (43.00 %), la digestibilité de l'extrait d'éther de T1 (96.42 %) est plus élevé que les autres groupes ayant le plus faible taux de T4 (95.25 %). Il y avait une digestibilité déprimante des cendres en T5 (68.30 %), inférieure à celle des autres groupes ayant le taux le plus élevé en T1 (82.59 %). L'étude a donc conclu que les agriculteurs peuvent remplacer les aals de blé par 25 % de croûte de pastèque dans le régime de démarrage des poulets à griller sans aucun effet délétère dans la performance de croissance et la digestibilité des nutriments.

Weaner Pigs

Thirty (30) weaned crossbred (Landrace × large white) pigs with an average body weight of 8.5±0.4 kg was used to evaluate performance and nutrient digestibility of weaned pigs fed five experimental diets containing cereal milling by-products. Diet 1 contained maize offal, while diets 2, 3, 4 and 5 contained wheat offal, sorghum offal, millet offal and rice offal respectively. The animals were balanced for sex and weight then allotted to five dietary treatments replicated three times in a completely randomized design. Data were collected on feed intake and weight gain for a period of eight weeks. A digestibility trial was carried at the end of the feeding trial using three pigs per treatment. Data collected were subjected to oneway analysis of variance. The result of growth performance and nutrient digestibility showed that average feed intake, final body weight as well as digestibility of dry matter, crude fibre, ether extracts, crude protein and ash were higher (P<0.05) for pigs fed T1 (maize offal), T2 (wheat offal), T3 (sorghum offal) and T4 (millet offal), while those on T5 (Rice offal) had the lowest growth and nutrient digestibility. It was concluded that maize offal, wheat offal, sorghum offal, millet offal can be used in weaner pigs' diet.   Trente (30) porcs croisés sevrés (Landrace × Large white) d'un poids corporel moyen de 8,5 ± 0,4 kg ont été utilisés pour évaluer les performances et la digestibilité des nutriments de porcs sevrés nourris avec cinq régimes expérimentaux contenant des sous-produits de la mouture de céréales. Le régime 1 contenait des as des aliments de maïs, tandis que les régimes 2, 3, 4 et 5 contenaient respectivement des aliments de blé, des aliments de sorgho, des aliments de mil et des aliments de riz. Les animaux ont été équilibrés pour le sexe et le poids puis attribués à cinq traitements diététiques répétés trois fois dans une conception complètement aléatoire. Des données ont été recueillies sur la prise alimentaire et la prise de poids pendant une période de huit semaines. Un essai de digestibilité a été réalisé à la fin de test d'alimentation en utilisant trois porcs par traitement. Les données collectées ont été soumises à une analyse unidirectionnelle de la variance. Le résultat des performances de croissance et de la digestibilité des nutriments a montré que l'apport alimentaire moyen, le poids corporel final ainsi que la digestibilité de la matière sèche, des fibres brutes, des extraits d'éther, des protéines brutes et des cendres étaient plus élevés (P <0,05) pour les porcs nourris au T1 (aliments de maïs). , T2 (aliments de blé), T3 (aliments de sorgho) et T4 (aliments de millet), tandis que ceux de T5 (aliments de riz) avaient la plus faible croissance et digestibilité des éléments nutritifs. Il a été conclu que les aliments de maïs, les aliments de blé, les aliments de sorgho, les aliments de millet peut être utilisé dans l'alimentation des porcs sevrés.

AbstractSeven, 3-year-old pony mares (~230 kg) were used in a cross-over study to compare the appetite, energy and nutrient digestibilities, growth rate and feeding behaviour, when a complete diet was offered ad libitum in either the original loose-chaff mix (C), or as a more convenient, milled and pelleted preparation (P). Ad libitum access to the study diet (gross energy = 17·2 MJ/kg dry matter (DM)) was attained over 2 weeks. In the following 4 weeks, groups 1 (no. = 3) and 2 (no. = 4) received pelleted and chaff-based diets respectively. Dietary forms were exchanged during week 5 and ad libitum provision continued for a further 4 weeks. Behaviour and apparent nutrient digestibilities were assessed in weeks 3 and 4 of each period. Pelleted food had a lower proportion of water (P, 0·12; C, 0·22), but relative proportions of oil (0·04), crude protein (0·08), crude fibre (0·29), neutral-detergent fibre (NDF; 0·53) and gross energy (GE) were neither altered by food processing nor time. Apparent digestibilities (DM, 0·49; GE, 0·50; NDF, 0·40 in period 1) of the pelleted and chaff-based diets were similar within periods but decreased (P 0·01) to a similar extent for both diet types (proportional changes: DM, –0·14; GE, –0·16; NDF, –0·28) in period 2. Overall, mean intakes of digestible energy (DE) for chaff-fed animals during period 1 were 0·73 (P 0·001) of pellet DE intake (DEI). Mean DEI of pellets increased (P 0·001) during period 1 to attain 1·76 (s.e. 0·25) MJ/kg M0·75 on day 25. Following transfer from pellets to chaff, DEI decreased (P 0·001) to 0·68 (s.e. 0·07) MJ/kg M0·75 by the end of period 2. In contrast, DEI of animals which progressed from chaff to pellets remained relatively constant between periods. Oestrous behaviour caused no detectable change in the appetite of individual mares. Irrespective of differences in DEI, average daily gain (ADG) in body weight and condition score (CS) did not differ between groups. Overall, mean ADG decreased (P 0·01) from 1·54 (s.e. 0·17) kg/day in period 1 to 0·26 (s.e.0·08) kg/day in period 2. Changes in body weight were associated with CS (R2 = 0·72). Each CS point represented a 53·4 (s.e. 4·8) kg gain in body weight. Chaff meals were longer (30·6 (s.e. 1·6) min, P 0·001), less frequent (23·8 (s.e. 1·4) per day, P 0·001) and associated with a lower bite rate (3·8 (s.e.0·2) per min, P 0·001) and increased chewing requirement (23 (s.e. 1·2) per bite, P 0·001), which decreased the rate of DM intake (17·0 (s.e. 0·9) g/min, P 0·0.01). Overall, chaff-fed animals spent more time feeding (0·50 (s.e. 1·3) of the time; P 0·0.01), primarily at the expense of non-feeding activity and rest. The ad libitum feeding regime enabled stabled ponies to re-establish natural feeding patterns and offers a viable alternative to meal and forage feeding. The more slowly ingested chaff form maximized time spent feeding and limited changes in DEI during the introductory period. Although CS and ADG increased over the first 4 weeks, growth and appetite returned to near maintenance values within 9 weeks in association with a decrease in dietary energy intake and nutrient digestibility.

Conventional feed resources for livestock are increasingly becoming more expensive, due to competition with man; hence nutritionists are searching for cheaper, locally-available alternatives. A total of forty-five (45) mixed sex weaner rabbits, aged 5 – 6 weeks, with average initial weights of between 694.42 and 761.10 g were used to investigate the effect of varying levels of cowpea milling waste (CMW) diets on their growth performance and nutrient digestibility. They were randomly allotted to five dietary treatments with nine rabbits per treatment. The control treatment (T1) contained 0 % CMW while treatments T2, T3, T4 and T5 had 10, 20, 30 and 40 % CMW dietary inclusion levels, respectively. Clean water and feed were offered ad libitum daily to the rabbits, and record of their feed intake and growth performance were taken for 12 weeks. At the end of the 11th week, a nutrient digestibility trial was carried out. Results show that there were no significant (P>0.05) differences in final body weight, body weight gain, total feed intake and mortality among the dietary treatments. Feed conversion ratio (FCR) for diets T4 (6.65) and T5 (6.66) containing 30 and 40 % CMW respectively, were as good as that of the control diet (6.11). Dry matter and crude protein digestibility showed no significant (P>0.05) difference across the treatments. Digestibility of crude fibre (72.64, 80.16, 84.04 and 80.90 % for T2, T3, T4 and T5 respectively), ether extract (95.98, 94.90, 96.04 and 94.38 % for T2, T3, T4 and T5 respectively), nitrogen free extract (94.30, 95.18, 93.58 and 94.90 % for T2, T3, T4 and T5 respectively), as well as total digestible nutrient (83.69, 76.11, 81.67 and 80.02 % for T2, T3, T4 and T5 respectively) of the test diets compared favourably with that of the control diet (72.94, 95.23, 96.04 and 80.47 % for CF, EE, NFE and TDN respectively). Hence, it can be concluded that CMW can be used safely as a protein source and included up to 40 % in weaner rabbit diets with no detrimental effect on their growth performance and nutrient digestibility.

Abstract BACKGROUND: A total of one hundred and forty, 28 d-old weaner pigs [Duroc x (Yorkshire x Landrace)] with initial body weight (BW) of 6.56±1.25kg were used in a six-week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low nutrient density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, fecal microbial, and gas emission of weaner pigs. RESULTS: Pigs fed low-density diet with probiotic mixture supplementation had linearly increased (P = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (P=0.018, 0.014, 0.014) at week 3, 6, and overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of low-density diet with probiotic mixture supplementation has improved the fecal lactobacillus counts linearly, but E. coli was unaffected during the trail. On day 42, Ammonium gas emission was significantly decrease in pigs fed a low-density diet with probiotic mixture supplementation. However, H2S, acetic acid, and CO2 were not significantly affected by the probiotic mixture supplementation diet. CONCLUSION: Low-density diet with probiotic mixture supplementation had positively affected the growth performance, fecal microbial, and fecal gas emission on weaner pigs.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

Jack Bean

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.

Yeast Concentration

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

Twelve ram lambs of the West African Forest type of between 15.7 and 24.6 kg were divided into four groups of 3 animals each. A group was assigned to one of four diets consisting of the following concentrate: grass hay ratios - 20 : 80 (A), 40 : 60 (B), 60 : 40 (C) and 80 : 20 (D). Feed intake, nutrient digestibilities and efficiency of feed utilization were measured. As the level of concentrate increased, the contents of crude protein ether extract, nitrogen-free extract (NFE) and gross energy of the diets increased, while the crude fibre and ash contents decreased almost linearly. Voluntary feed intake increased with increasing levels of concentrate, with diet C having a significantly higher (P 0.01) Relative Intake (RI) value than the other diets. Both the Nutritive Value Index (NVI) and Digestible Energy (DE) intake values were significantly higher (P. 0.01) in diets C and D than the other diets. Generally, the digestion coefficients for the gross energy, crude protein, crude fibre and nitrogen free extract increased with increasing levels of concentrate, the values being significantly higher (P 0.01) in diets C and D, while diet A showed a significantly lower (P 0.05) dry matter digestion coefficient value when compared with either diets. Although a similar trend was observed in the digestion coefficient for ether extract, the differences were not significant (P 0.05). With the exception of animals on diet C which had the highest daily weight gains, average daily weight gains and efficiency of feed utilization increased with successive substitution of concentrate for grass hay.

A ten-week feeding trial was conducted to evaluate the apparent nutrient digestibility of 120, one-day old broiler starter chicks fed varying levels of Parboiled sundried taro cocoyam (Colocasia esculenta) meal (PSCM). Four treatments were formulated with diet one containing 100% maize as control, while in diet two, three and four parboiled sundried cocoyam meal (PSCM) replaced the percentage proportion of maize in diet one at 50, 75 and 100% inclusion levels respectively. Thirty (30) birds were randomly assigned to the four treatment diets in a complete randomized designed (CRD) and each treatment group contained three replicates with ten (10) birds each. Ground fed feed and voided faecal samples collected after a 4-day feeding in a metabolic cage were analyzed for their respective proximate constituent. Apparent nutrient digestibility revealed that crude fibre was significantly (P<0.05) higher in diet 4 while crude ash was significantly (P<0.05) higher in control. Digestible ether extract and NFE were significantly (P<0.05) higher among birds placed on 50% PSCM. It is therefore concluded that parboiled sundried taro cocoyam meal (PSCM) could replace 50% of maize in broiler starter diet without any deleterious effect. However, substituting maize with parboiled sundried taro cocoyam meal at 50% replacement level improved nutrient digestibility and is hereby recommended for poultry farmers.
