A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

A study was carried out to determine the effect of Crina Poultry Plus®, a natural blend of essential oils and benzoic acid. on the growth performance, carcass yield and nutrient digestibility of broiler chickens. Six treatment diets were formulated by the addition of Crina Poultry Plus (CPP®) at 0, 0.2, 0.3, 0.4, 0.5 and 0.6g/kg of feed. Two hundred and forty day-old chicks were allocated to the six dietary treatments with each treatment having four replicates. Each replicate had 10 broilers. The parameters measured were live weight, live weight gain, feed intake, feed conversion, protein efficiency ratio, carcass and organ    characteristics, nutrient utilization and feed cost benefit. Results of growth performance showed that there were no significant differences (P>0.05) across the treatment groups, but birds fed diets supplemented with CPP® had significantly heavier body weight (BW), higher average daily weigh gain live weight gain and similar feed conversion ratio when compared with the control group. The dressing percentage, thigh, drum stick, breast cut and back cut were not significantly (P>0.05) different across the treatment groups but those fed diet supplemented with CPP® had higher values when compared with the control diet. The supplementation of CPP® improved nutrient digestibility in broiler chickens. Birds fed diet containing 0.6g of CPP® had numerically lower cost per kg of weight gained compared to other treatment groups. It can be concluded that the addition of 0.6 g CPP® in broiler diets improved performance, carcass, organ characteristics and nutrient utilization of broilers.

Abstract We previously found that i.m. injection of GRA, similar to in-feed antibiotics, improves measures of intestinal integrity, nutrient digestibility, and overall growth performance in nursery pigs. In addition, we have demonstrated that the mitigating effects of GRA on the stress of weaning is predominantly done by subsiding the inflammatory response that often accompanies early weaning. The objective of the current study was to explore the most practical methods for delivering GRA to newly weaned pigs. One-hundred and sixty-seven PIC pigs were weaned at 25 ±1.0 days of age (BW 7 ±1.2 kg), and assigned to fourteen treatments (3-4 pigs /pen; 3 pens/treatment). Seven treatments were tested within two sexes (gilts vs. barrows). The treatments were: 1) i.m. injection of GRA (two injections, 0.2 mg/kg BW at -1 and 3 d post-weaning), 2) two levels of in-water GRA (0.8 and 1.6 ppm), 3) in-feed GRA (2.5 and 5.0 ppm), 4) in-feed antibiotic (ANT, 100 ppm tylosin), and 5) control. Dexamethasone was used as GRA. Pigs had free access to in-feed or in-water GRA or ANT during the 1st-week post-weaning. Parameters of growth performance were measured weekly until the end of the nursery phase. A completely randomized design and repeated measurement ANOVA (PROC MIXED) in SAS were used for statistical analyses. In-water, in-feed, and i.m. GRA treatments resulted in growth performance outcomes comparable to that of in-feed ANT. Relative to CON pigs, both ANT and GRA improved ADG and G: F during the nursery phase (P &lt; 0.05). Among the delivery methods tested, 2.5 ppm of in-feed GRA resulted in superior ADG (GRA vs. CON; 0.29 vs. 0.20 kg/d) and G: F (0.63 vs. 0.40 ± 0.05), compared to the control group (P &lt; 0.02). Collectively, these results suggested that in-feed treatment is the best method for delivering GRA to newly weaned pigs.

Abstract The objective was to determine the functional and nutritional values of Corynebacterium glutamicum Cell Mass (CGCM) on growth performance and gut health of newly-weaned pigs. Forty newly-weaned pigs (21 d of age; initial BW 7.1 ± 0.4 kg) were allotted to 5 dietary treatments based on randomized complete block design with sex and BW as blocks. The lysine broth of CGCM (CJ Bio, Fort Dodge, IA) was homogenized by using French press and dried to obtain lysed CGCM. Dietary treatments were: basal diet with lysed CGCM at 0, 0.7, 1.4, 2.1%, and with 1.4% intact CGCM. Experimental diets were formulated based on nutrient requirements (NRC, 2012) and pigs were fed based on 2 phases (10 and 11 d for each phase). Titanium dioxide (0.4%) was added to phase 2 diets as an indigestible external marker to calculate nutrient digestibility. Feed intake and BW were measured at d 0, 10, and 21. Pigs were euthanized on d 21 to collect proximal and distal jejunal mucosa to measure TNF-α, IL-8, MDA, IgA, and IgG concentrations. Diets and ileal digesta were collected to measure AID. Data were analyzed by SAS using MIXED, REG, and GLM procedures. Overall, increasing daily lysed CGCM intake increased (P &lt; 0.05) ADG (211 to 296 g) and ADFI (432 to 501 g). Increasing levels of lysed CGCM decreased (P &lt; 0.05) MDA and changed (quadratic, P &lt; 0.05) IgA (max: 4.90 ng/mg at 1.13%) and IgG (max: 3.37 ng/mg at 1.04%) in the proximal jejunal mucosa. Increasing daily lysed CGCM intake had quadratic effect (P&lt; 0.05) of protein carbonyl (max: 6.3 μmol/mg at 4.9 g/d). Lysed CGCM potentially benefits growth performance and gut health of newly-weaned pigs by reducing oxidative stress and increasing immune response.

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

High cost of conventional feedstuffs has resulted to the need to exploit the diverse feed resources for improved sustainability in swine production. Hydroponic sprouts which undergo nutritional modification during the sprouting process are a good source of nutrients that could improve the performance of pigs. Hence, nutrient digestibility, performance, haematological and serum biochemical parameters of weaned pigs fed hydroponic maize fodder (HMF) and conventional basal based diets were studied. Thirty-six (36) crossbred weaned pigs were randomly allotted to three treatments with four replicates each in a completely randomized design. Treatment 1 (T1) had 50% hydroponically grown maize sprouts + 50% concentrate, Treatment 2 (T2) had 100% hydroponically grown maize sprouts and Treatment 3 (T3) had 100% basal diet (cassava peel +palm kernel cake +brewery dried grain). The experiment lasted 6 weeks. Significant differences (P<0.05) were observed in the apparent digestibility of nutrients, performance and blood profile of pigs across dietary treatments. T1 had higher (P<0.05) apparent crude protein digestibility (65.76%) while the lowest (55.27%) was observed in T2 with a similar trend observed for apparent crude fibre digestibility. Apparent ether extract digestibility was higher (P<0.05) in T2 (68.43%) and lowest in T3 (65.47%) while ash digestibility was (P<0.05) highest in T3 (46.08%). Significantly higher values were obtained in T3 for final weight (13.83kg), feed intake (12.79kg) and weight gain (3.83kg) while least values were observed in T2. However, T1 had the highest value for FCR (3.68kg) while comparable values were obtained for feed cost/weight gain in pigs fed T1 and T3. T1 had higher (p<0.05) RBC (5.73×10 µl), WBC (1.80×10 µl), lymphocytes (69%) and eosinophils (3.67%) values while lowest values were obtained in T2 for PCV (34.67%), RBC (5.08×10 µl) and lymphocytes (56.33%). Significant differences (P<0.05) were also observed for cholesterol, triglycerides, LDL, VLDL, total protein, globulin and albumin while glucose and HDL showed no differences (P>0.05). All values obtained for haematology and serum biochemical parameters were within the normal physiological range of the animals.In conclusion, hydroponics maize fodder when combined with concentrate feed had a positive impact on nutrient digestibility and performance of pigs. Also, haematological and serum biochemical indices of pigs were not negatively affected.
