Abstract. Thirty rabbit bucks of mixed breeds (New Zealand white x Chinchilla) with average live weight of 852g, aged between 12 and 14 weeks were subjected to a feeding trial for 14 weeks, to determine the effects of diets with different ratio concentrate to fresh leaves of Gmelina arborea (FLGA) on growth performance, relative carcass weight and relative organ weights of rabbit bucks. The rabbits were randomly allo- cated into five treatments: Treatment 1-T1 (100g concentrate /C/: 0g FLGA), Treatment 2-T2 (75g C: 25g FLGA), Treatment 3-T3 (50g C: 50g FLGA), Treatment 4-T4 (25g C: 75g FLGA) and Treatment 5-T5 (00g C: 100g FLGA). The results obtained in this study showed that all the growth performance parameters and relative carcass weights differed significantly (P<0.05) across treatments. Apart from relative liver and lungs weights, which differed significantly (P<0.05) across treatments, other viscera organs were not affected by the dietary treatments. The results revealed that rabbit bucks in T2 and T3 performed better, rabbits in T4 performed the least, while rabbit bucks in T5 could not survive beyond two weeks. Concentrate to FLGA at the ratios of 75g C: 25 FLGA (T2) and 50g C: 50g FLGA (T3) are therefore, recommended as the best combinations for rabbit breeding bucks.

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

Abstract. Thirty (30) rabbit bucks of mixed breeds (New Zealand white x Chinchilla) with average live weight of 852g, aged between 12 and 14 weeks were subjected to a feeding trial for 14 weeks, to determine the effects of diets with different ratio concentrate to fresh leaves of Gmelina arborea (FLGA) on semen characteristics, testicular and epididymal morphometry of rabbit bucks. The rabbits were randomly allocated into five treatments: Treatment 1-T1 (100g concentrate /C/: 0g FLGA), Treatment 2-T2 (75g C: 25g FLGA), Treatment-T3 3 (50g C: 50g FLGA), Treatment 4-T4 (25g C: 75g FLGA), Treatment 5-T5 (00g C: 100g FLGA). The results obtained showed that sperm motility, concentration and percentage of live sperm cells showed significant effects (P<0.05), while semen volume and percentage of normal sperm cells were not significantly affected by the test diets. Rabbits on T4 did not ejaculate within the experimental period. Mean testis density was not significantly affected, while paired testes weight, mean testis length, paired testes volume, paired epididymal weight and mean epididymal length were significantly (P<0.05) influenced by the dietary treatments. The results revealed that rabbit bucks on T2 and T3 performed better, rabbits on T4 performed least, while rabbit bucks in T5 could not survive beyond two weeks. Concentrate to FLGA at the ratios of 75g C: 25g FLGA (T2) and 50g C: 50g FLGA (T3) are therefore recommended as the best combinations for rabbit breeding bucks.

Abstract This study was conducted at a commercial research facility and utilized 1,092 finishing pigs (PIC® 337 × Camborough®) in a RCBD with 3 dietary treatments to determine the effects of commercially available phytogenic feed additives on growth performance traits in finishing swine for the last 35 d prior to marketing. The dietary treatments were as follows: 1) Control; 2) Aromex Pro® (AP; Delacon) fed at 0.01%; and 3) Ambitine® (AM; PMI) fed at 0.1%. Pens with 13 pigs/pen and 0.66 m2/pig were randomly allotted to treatments on the basis of live weight and gender. Pigs had ad libitum access to corn-soy diets that met or exceeded the pig’s requirements (NRC, 2012). Aromex Pro® and Ambitine® were added to the diets at the expense of corn. Dietary treatments started on day 0 (BW = 97.7 kg; SEM = 1.04) and were fed throughout the 35 d trial period. On d 21, the two heaviest pigs per pen were marketed, while the remaining pigs in each pen were marketed on d 35. Pigs and feeders were weighed on d 0, 21, and 35. Data were analyzed by using PROC MIXED of SAS® version 9.4, and pen was the experimental unit. The model included the fixed effect of treatment and random effect of replicate. Pre-planned orthogonal contrasts were used to compare AP vs. Control and AM vs. Control. Feeding AP or AM for the last 35 d in finishing both improved (P &lt; 0.05) ADG by 4%, ADFI by 3% and final BW by 1.6 kg over Control, but did not change feed to gain or mortality. These data demonstrate that phytogenic feed additives can improve growth performance traits in finishing swine.

Abstract The objective of this experiment was to evaluate the effects of a phytogenic feed additive (PFA-F, Digestarom® Finish, BIOMIN America Inc.) on growth performance and carcass characteristics of grow-finish pigs compared to a control, two commercial PFA products (A and B), and a ractopamine feeding program. Two hundred pigs (Choice Genetics, BW = 24.88 ± 0.53 kg) were randomly allotted to 5 dietary treatments and fed diets based on 4 dietary phases. Dietary treatments consisted of: CON, a corn-soybean meal based diet; RAC, 4.5 ppm Ractopamine HCl was added into CON for the last 21 d; PFA-A (commercial product A) was added into CON when pigs reached 90 kg of BW; PFA-B (commercial product B) was added into CON from 75 kg of BW; PFA-F was added into CON from the beginning (25 kg of BW). Body weight and feed disappearance were recorded at the end of each phase, and carcass traits were measured at the end of the trial. Data were analyzed using the Mixed procedure of SAS. No differences were observed from phase 1 to phase 3 among the treatments. At the end of phase 4, RAC had a higher (P &lt; 0.05) BW than the CON, PFA-A, or PFA-B (127.5 vs.123.1 or 121.5 kg); however, no difference between RAC and PFA-F in BW (127.5 vs.124.0 kg) was found. Pigs fed PFA-F had a higher (P &lt; 0.05) hot carcass weight than those of fed CON or PFA-B (93.0 vs. 88.8 or 88.8 kg). No differences were found in lean percentage, fat depth, and loin depth among the treatments. In conclusion, PFA-F (Digestarom Finish) supplementation resulted in similar growth performance and hot carcass weight when compared to a Ractopamine feeding program during the grow-finish period, whereas either commercial product A or B had significantly lower performance than feeding Ractopamine.

Mannan Oligosaccharides

This study examined the effect of dietary treatments containing mannan-oligosaccharides (MOS) on some blood biochemical, haematological parameters and carcass traits of 60 weaned purebred New Zealand White (NZW) and New Zealand White × Rex (NZW × RX) crossbred rabbits. They were assigned to a 2 × 3 factorial arrangement (two genetic groups; and three dietary treatments of zero, 0.5 or 1.0 g MOS/kg of diet). Blood samples have been collected at slaughter at 10 weeks of age. Significant differences were observed among dietary treatments for all biochemical and haematological parameters with the exception of triglycerides. There was a genetic group and dietary treatment interaction for albumen (P < 0.001), cholesterol (P = 0.002), red blood cell count (RBC) (P = 0.007), haemoglobin (Hb) concentration (P = 0.009) and haematocrit % (P < 0.001) observed. Rabbits from the NZW × RX genetic group fed a diet with 1.0 g/kg MOS had the highest plasma cholesterol level (0.97 ± 0.012 mmol/L), whereas the lowest level (0.89 ± 0.012 mmol/L) was detected in rabbits from the NZW × RX genetic group fed the Control diet. Rabbits from the NZW genetic group fed the diet with 1.0 g/kg MOS had the highest RBC (4.27 ± 0.083 × 106/mm3) whereas rabbits from the same genetic group fed the diet with 0.5 g/kg MOS had the highest Hb concentration (11.43 ± 0.097 g/dL) and haematocrit (30.29 ± 0.163%). Some carcass traits such as liveweight, hot and reference carcass weight (P < 0.001), percentage of periscapular, and perirenal fat relative to reference carcass weight (P < 0.05) were significantly affected by the dietary MOS supplementation. In conclusion, MOS supplementation in the diet, especially 1.0 g/kg, improved immunity, health indicators in the blood, liveweights and carcass weights of rabbits without any harmful effects on the other carcass traits. Furthermore, purebred NZW and NZW × RX crossbred rabbits showed relatively similar performance for all traits of interest. A significant interaction between genetic group and dietary supplementation of MOS was shown for albumen, cholesterol, RBC and haematocrit %.

AbstractThis experiment was conducted to evaluate the effects of replacing soybean meal (SBM) with treated rape-seed meal (tRSM) on the growth performance, blood mineral levels and fatty acid composition of back fat in growing-finishing pigs. A total of 12 crossbred pigs (Slovakian White × Landrace) with an initial live weight of 40.82 ± 2.69 kg were divided into two dietary treatments. The experimental period lasted 84 days; 38 days in the growing period and 46 days in the finishing period. The dietary treatments were as follows: control, a SBM-based diet (growing and finishing), and experimental, a treated RSM-based diet (growing and finishing). The rapeseed meal was treated with a product that neutralizes the negative physiological effects of anti-nutritive glucosinolates contained in rapeseed products for livestock feeding. Our analysis showed minor, no significant negative effects of tRSM on live weight, average daily gain and feed conversion ratio. Replacing SBM with tRSM had no significant effects on the proportion of the total saturated, monounsaturated and polyunsaturated fatty acids of back fat samples, as well as concentrations of analysed serum minerals except zinc level. In conclusion, the inclusion of 25 % and 18 % of treated RSM in growing and finishing pig diets had no negative effects on the growth performance, blood mineral profile or fatty acid composition of back fat.

A biological experiment of 160 day old chicks for six weeks was undertaken with completely randomized design (CRD) divided into five treatments, each consisting of 4 replicates and 8 chicks in each replicate. Five experimental diets as per ICAR (2013) were prepared by incorporating rice distillers dried grains with solubles (rDDGS) at inclusion level of (0, 7.5, 10.0, 12.5 and 15.0%). Chemical analysis revealed that rice DDGS on as such basis is high in both crude protein 44.68% and gross energy 4232 kcal/kg. In vitro pepsin-pancreatin digestibility (IVPPD) of rDDGS was found 79.81%. At the inclusion level of 7.5, 10 and 12.5 %, growth performance and nutrient utilization did not show any significant (P>0.05) difference as compared to control but at 15% rDDGS inclusion level, growth performance (body weight gain, feed intake and FCR) and nutrient utilization (dry matter and energy metabolizability, nitrogen retention %) were significantly (Pless than0.01) lower in 15% rDDGS (T5) group as compared to control (T1) and other dietary treatments. Carcass traits did not show any significant (P>0.05) difference between control and other dietary treatments. Cost of production per kg live weight and meat yield were significantly (Pless than 0.01) lower in 7.5 % and above rDDGS levels. Thus, it is concluded that rDDGS can be safely incorporated in broiler chickens diets up to the inclusion level of 12.5% as alternate protein meal for economic broiler production.

A study was conducted to determine the growth performance and carcass characteristics of indigenous Venda chickens fed a grower’s diet supplemented with varying levels of garlic meal. The study was based on four diets containing similar energy but different garlic meal supplementation levels of 0, 10, 15 and 25 g/kg DM. At 50 to 91 days, all the growth and carcass parameters measured were improved (P less than 0.05) by garlic meal supplementation. Feed intake, growth rate, feed conversion ratio, live weight, carcass weight, dressing percent, breast meat, thigh, drumstick, gizzard and fat pad weights of Venda chickens were optimized at different garlic meal supplementation levels of 14.7, 15.8, 8.0, 16.4, 14.2, 12.7, 11.2, 12.7, 8.2, 10.5 and 15.1, respectively. These findings have implications on ration formulation for indigenous Venda chickens. Thus, it was concluded that garlic meal supplementation improved feed intake, growth rate, live weight and carcass weight of Venda chickens.

The effect of plant extracts (PE; artichoke, celery, beet, onion, garlic, spinach, avocado, oats, and parsley) in the diet of growing pigs under heat stress was investigated. Parameters included growth performance, blood constituents, carcass characteristics, organ percentage, quality and sensory appraisal of the pork. The study was performed during the Mexican summer, using 60 pigs. Treatments included the control, to which 0.1% PE, and 0.15% PE were added. The use of PE (0.1 and 0.15%) generated an increase in the average daily gain (ADG, by 10.0% for both treatments), and final live weight (LW, by 6.3% and 6.8%) (p < 0.05). The level of blood albumin at 95 kg was higher when supplementing with 0.1% PE (p < 0.05). At 120 kg LW, creatine kinase values showed a tendency to be different (p = 0.07). Carcass weight increased (p < 0.05) when adding PE. Supplementation with 0.1% PE decreased (p < 0.05) the red/green (a *) hue of the meat, whereas supplementation with 0.1% and 0.15% PE increased the yellow/blue (b *) hue (p < 0.05). The addition of PE improves pig growth performance, and carcass weight by reducing the negative effects of heat stress, without markedly modifying blood constituents, meat quality, and sensory attributes of the pork.

Abstract Maine-Anjou x Angus steers (n = 156, initial BW 366 ± 37.2 kg) were used in a 132-d finishing experiment at the Ruminant Nutrition Center in Brookings, SD. Steers were weighed on two consecutive days and assigned into 5 weight blocks. Within each weight block steers were randomly assigned to two implant types (equal steroidal hormone dose; both from Zoetis, Parsippany, NJ) and two dietary treatments in a 2 × 2 factorial arrangement. Implant treatments consisted of 1) Coated implant, 200 mg trenbolone acetate (TBA), 28 mg estradiol benzoate (EB) (Synovex ONE Feedlot, ONE) or 2) Non-coated implant, 200 mg TBA, 28 mg EB (Synovex PLUS; PLUS), placed in the left ear. Dietary treatments were 1) 15% or 2) 30% corn silage (DM basis). No interaction between implant and corn silage inclusion was observed for carcass-adjusted (hot carcass weight / 0.63) growth performance, dietary net energy (NE) utilization or carcass traits (P ≥ 0.16). Bunks were managed using a slick bunk approach and all diets contained (DM basis) 33 mg/kg monensin sodium. Implant status was checked on d 28 by a single trained evaluator; steers with missing implants were immediately re-implanted. There was no difference in carcass-adjusted growth performance between implants (P ≥ 0.85). There were no differences in observed NE or the observed-to-expected ratio of NE for either growth or maintenance (P ≥ 0.90). No differences were observed for dressing percent, hot carcass weight, ribeye area, or rib fat (P ≥ 0.22). Marbling differed between implant treatments (433 to 466 ± 8.7; P = 0.01) for PLUS and ONE respectively. Implanting cattle with a coated implant had no detrimental effect on growth performance or carcass traits, but it did increase marbling scores.
