Sixteen Newzealand White rabbits aged 9.5 = 0.5 weeks weighing 0.72-0.99kg were used to evaluate the experimental rations which allowed for good weight gain. They were divided into 4 groups and allotted four different diets for the treatment groups with 10, 13, 16 and 20% CP. Feed intake (FI) for the treatment groups were 58.52, 61.46, 57.35, and 61.06g while average daily gain (ADG) were 4.22, 4.35, 5.32 and 6.02g for the groups. There were significant increase (P<0.01) in the digestibility of CP, EE and NFE within the treatment groups. Diets containing 16-20% CP may provide adequate nutrients for optimum weight gain of Newzealand rabbits.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

A total of 48 large white pigs were used in an experiment to investigate the use of exogenous testosterone on the growth of pigs. The pigs were randomly selected as day old piglets, balanced for weight with equal number for each sex, and allotted to two treatment groups, T1, which received Testosterone Enanthate (TE), intramuscularly, weekly, for 24 weeks and T2, the control, which received no hormone but blank injections. Dosage was based on live weight (1.2mg/kg live weight). Corn oil served as the vehicle. The parameters measured include Total weight gain (TWG), Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and Feed Conversion Ratio. The results obtained showed that exogenous testosterone increased weight gain significantly (p<0.05) in both sexes than their respective controls. The same trend was observed for feed intake and feed conversion. Exogenous testosterone also indicated pronounced sex effect on the pigs in this study with males having significantly (p<0.05) higher values than females. It can be concluded from this study that exogenous testosterone can be used to accelerate growth thereby finishing the pigs early. A withdrawal period of 4 weeks before slaughter is however recommended.

Abstract The aim of the present study was to explore the influences of varying doses of micelle silymarin (0, 0.05%, 0.1%, and 0.2%) supplementation on sows’ feed intake, milk yields, serum hormones, and litter growth using 40 multiparous sows (Landrace × Yorkshire, parity from 3-5) from the109 th prenatal day to the 21 st postnatal day. Each treatment included 10 sows and each sow was used as an experimental unit. On weaning day, litter weight and litter weight gain were linearly improved (P &lt; 0.01, both), corresponding to the increasing dose of silymarin micelle in the diet. Also, litter weight, litter weight gain, and average daily gain (ADG) of piglets born to treated sows exceeded (P &lt; 0.05) those of offspring from the control sows (0% micelle silymarin). Feed intake in week1, week2, and the entire lactation period were increased (linear, P &lt; 0.01) as micelle silymarin dose increased. Body weight (BW) loss of sows during lactation was linearly reduced (P = 0.003) with the increasing amounts of micelle silymarin. Average daily milk yields during lactation were also linearly increased (P = 0.002) in treated sows, exceeding (P = 0.046) that of control sows. Also, uniform increases were observed (P = 0.037) in fat content in milk produced by treated sows on d 14 of lactation. Epinephrine concentrations and aspartate aminotransferase (AST) activity in sow serum on d 21 postpartum were linearly declined (P = 0.010) as micelle silymarin dose increased, and were both declined (P &lt; 0.05) in treated sows compared with the control. In addition, treated sows’ serum had higher activity of superoxide dismutase (SOD) at parturition and glutathione peroxidase (GSH-Px), lower oxidized glutathione (GSSG) concentrations, and GSSG/GSH (glutathione) ratio (all, P &lt; 0.01) on d 21 of lactation. Moreover, offspring from micelle silymarin-treated sows tended to (0.05 &lt; P &lt;0.1) have higher serum catalase (CAT) activity and total antioxidant capacity (T-AOC) concentrations. Taken together, the results showed that sows fed increasing levels of micelle silymarin from the109 th prenatal day to the 21 st postnatal day had an incremental dose-dependent effect on higher feed intake, diminished BW loss, greater milk yields, and greater litter weight at weaning, and 0.2% of micelle silymarin could be optimal to achieve the better effect.

A feeding trial was conducted to investigate the optimum level of dietary protein and energy on production performance and carcass characteristics of quail. A total number of 128 day-old chicks of Dhakai quail were used from internal hatchery of Bangladesh Livestock Research Institute, Savar, Dhaka. The chicks were arranged according to a 4 × 2 factorial (4 protein levels; 20, 22, 24 and 26% and 2 energy levels; 2800 and 2900 kcal ME/kg), and allocated into eight dietary treatment combinations according to the experimental design. The combinations were designated as D1 (CP20ME2800), D2 (CP20ME2900), D3 (CP22ME2800), D4 (CP22ME2900), D5 (P24ME2800), D6 (P24ME2900), D7 (P26ME2800) and D8 (P26ME2900). There were 16 chicks per treatment, each treatment had 2 replications having 8 chicks in each. At the end of 5 weeks, 2 birds from each replication were randomly selected and slaughtered to analyze the meat yield traits. All birds were fed ad libitum with treatment diets from day-old to 35 days of age. There were significant effect (P<0.001) of crude protein levels on final body weight, total weight gain, daily gain, feed intake and feed conversion ratio (FCR). Feed intake, total weight gain and FCR at different energy levels did not differ significantly (P>0.05). It was observed that the performance of Dhakai quail fed diet with 22% crude protein and 2900 kcal. ME/kg DM was better compared to others in terms of total gain, daily gain, FCR and dressing percent. Futher, treatments effect of protein level was observed on weight gain from day-old to 35 days. A crude protein level of 22.227% was estimated by regression equations for growing Dhakai quail.Bangladesh J. of Livestock Res. 19(1-2): 1-9, Jan-Dec 2012

The positive effects of nucleotide (NU) supplementation in milk replacer have been elucidated in infants and in dairy calves; however, NU addition to whole milk has not been evaluated previously. This study aimed to assess NU supplementation in the whole milk on calf growth and health. Thirty Holstein calves (body weight: 39.1 ± 1.0 kg; 3 d after birth) were randomly assigned to the following treatments: whole milk without any supplementation (NU0), whole milk + 0.5 g/d added a NU-containing supplement to whole milk (NUCS0.5), and whole milk + 1 g/d added a NU-containing supplement to whole milk (NUCS1). Calves were weaned at d 55 and stayed on study until d 75. Calves had free access to feed and water throughout the study. Dry matter intakes (DMI) were similar among treatments (p > 0.05) during the pre-weaning period; however, increasing NU resulted in a linear (p < 0.05) increase in DMI during the post weaning period (2158, 2432, and 2518 g/d for NU0, NUCS0.5, and NUCS1, respectively). Treatments did not affect body weight (BW) at the first and second month of study, but final BW linearly increased as NU was added (87.1, 90.6, and 95.4 kg for NU0, NUCS0.5, and NUCS1, respectively). Neither pre-weaning average daily gain nor post-weaning average daily gain was affected by treatments; accordingly, feed efficiency was similar among treatment groups. Days with loose fecal score were linearly decreased as NU was added to whole milk during the first month of life, while the fecal score did not differ among treatments until the end of the study. No difference was observed in the skeletal growth of calves in the current study. Therefore, it can be concluded that NU supplementation in the whole milk has some beneficial effects on calf performance in terms of final BW, post-weaning DMI, and less days with loose feces.

Abstract Annual ryegrass (Lolium multiflorum Lam.) can be divided into two cytotypes: diploid (2n = 2x) and tetraploid (2n = 4x). Polyploid versions of a given plant species result in increased seedling vigor, more robust growth and, potentially, greater yield. While most data suggest no difference in yield between diploid and tetraploid cultivars, there is still potential for weight gain advantages thanks to increased non-structural carbohydrates in tetraploid cells. The objectives of this study were to compare weight gain of cattle grazing either diploid or tetraploid cultivars of annual ryegrass. Two diploid annual ryegrass cultivars (Marshall and Tam 90) and two tetraploid cultivars (Jumbo and Nelson) were planted in 0.81-ha pastures, each replicated four times. Four steers (mean initial BW = 214 kg) were randomly assigned to each pasture for an 82-d grazing period. Body weights were recorded starting at d0 then every 28 days throughout the season. Data were analyzed in the GLM procedure of SAS using a significance level of α = 0.05. There were significant differences between cytotypes with respect to seasonal yield with diploids (9547.90 kg/ha) yielding greater than tetraploids (7762.00 kg/ha). As expected, ADF and NDF fractions were significantly less for tetraploids (ADF; 31.39%, NDF; 31.39%) compared to diploids (ADF; 33.75%, NDF; 53.25%). Tetraploids also contained significantly greater crude protein (13.50%) than diploids (12.90%). Cytotype had no effect on final average daily gain (ADG) (P = 0.9427). However, final ADG was significantly impacted by cultivar (P = 0.0134). Final ADG for Tam 90 (1.10 kg/d) was greater than Marshall (0.92 kg/d). Cattle grazing Nelson (1.04 kg/d) and Jumbo (0.99 kg/d) did not differ. Results show that regardless of differences in seasonal yield and nutritive value between cytotypes, there were no advantages in ADG for cattle grazing either cytotype.

Abstract This experiment evaluated the impacts of bovine appeasing substance (BAS) administration on performance, health, and physiological responses of feedlot cattle during a 45-d receiving period. A total of 342 recently-weaned Angus-influenced steers, originating from 16 cow-calf operations, were obtained from an auction yard on d -1 and road-transported (12 h) to the feedlot. Upon arrival on d 0, body weight (BW) was recorded and steers were ranked by BW and source and assigned to receive BAS (Nutricorp, Araras, SP, Brazil; n = 171) or placebo (diethylene glycol monoethyl ether; CON; n = 171). Treatments (5 mL) were topically applied to the nuchal skin area of each animal. Within treatment, calves were allocated to 1 of 24 drylot pens (12 pens/treatment) and received a free choice total-mixed ration from d 1 to 45. Calves were assessed for bovine respiratory disease (BRD) signs and feed intake was recorded from each pen daily. Steer BW was again recorded on d 1, 7, 17, 31, and 45, whereas blood samples were collected from 5 steers/pen concurrently with each BW assessment. Average daily gain was greater (P = 0.05) in BAS vs. CON calves, although final BW did not differ (P = 0.36) between treatments. No treatment effects were detected for feed intake (P = 0.95), resulting in greater (P = 0.05) feed efficiency in BAS vs. CON steers. No treatment effects were detected (P ≥ 0.37) for plasma concentrations of haptoglobin, whereas plasma cortisol concentrations were greater (P = 0.05) in CON vs. BAS steers on d 7 (treatment × day; P = 0.07). Incidence of BRD was greater (P ≤ 0.05) in BAS vs. CON on d 6 to 10 and d 18 to 21 (treatment × day; P &lt; 0.01), although overall BRD incidence did not differ (P = 0.24) between treatments. The number of antimicrobial treatments required per steer diagnosed with BRD symptoms to recover from sickness was greater (P = 0.04) in CON vs. BAS calves. No treatment differences were detected (P ≥ 0.41) for mortality incidence, or proportion of steers removed from the experiment due to extreme sickness. Results from this experiment indicate BAS administration upon feedlot entry improved average daily gain by enhancing feed efficiency. Administration of BAS facilitated earlier detection of BRD and reduced the need for antimicrobial treatments. Collectively, these results suggest BAS administration as a promising strategy to benefit performance and immunocompetence of feedlot receiving cattle.

Forty-eight crossbred pigs of average initial weight 21 kg were fed 10% Tower rapeseed meal (RSM) and 10% Candle RSM as partial replacements for soybean meal (SBM). Diets were formulated to be isocaloric. Pigs fed the SBM diet consumed less feed, gained significantly (P < 0.01) faster and were more efficient at converting feed to gain than those fed the RSM diets. Performance of pigs fed Candle RSM was not significantly different to that obtained with Tower RSM. In a second experiment, dehulled Tower RSM and Tower RSM hulls were mixed in amounts to produce RSM with crude fibre levels of 6.8, 10.8, 13.5 and 15.8%. The simulated RSM and Tower and Candle RSM were used to completely replace SBM in the diets of weanling (75 g) Sprague-Dawley rats. Rats fed SBM had significantly (P < 0.05) higher average daily gain (ADG) than those fed Tower or Candle RSM, or diets containing the rapeseed meats. There was no significant (P < 0.05) difference in ADG, feed intake or feed to gain ratio of rats fed either Tower or Candle RSM. Feed intake, feed to gain ratio and fecal volatile fatty acid concentrations increased while average daily gain decreased with increasing level of hulls in simulated RSM diets. There was no significant difference (P < 0.05) in thyroid weight between rats fed SBM, Tower RSM or Candle RSM.

Abstract Objectives were to compare feedlot performance and carcass traits of F1 beef × Holstein steers and Holstein steers. Angus or Limousin × Holstein crossbred [n = 27; age = 12 ± 3 months; body weight (BW) = 435 ± 8 kg] and Holstein (n = 20; age = 11 ± 2 months; BW = 400 ± 9 kg) steers were fed at the Pennsylvania Department of Agriculture Livestock Evaluation Center for 111 days. Feed intake was recorded using the GrowSafe Feed Intake Monitoring System (Model 4000E, GrowSafe Systems Ltd., Calgary AB, Canada). The diet contained corn silage, dried distillers grains, soybean meal, and cracked corn and was formulated to meet or exceed the requirements of beef cattle (NASEM, 2016). Growth performance variables of interest and carcass measurements were analyzed with the Mixed procedure of SAS (SAS 9.4; SAS Institute Inc., Cary, NC). USDA assigned quality grades (QG) and yield grades (YG) were analyzed the with GLIMMIX procedure of SAS. Breed was a fixed effect in all models. There were no differences (P &gt; 0.05) between breeds in average daily gain or feed efficiency. Crossbreds exceeded Holsteins in initial (P &lt; 0.01) and final BW (P = 0.01), dry matter intake (P = 0.03), hot carcass weight (P &lt; 0.01), backfat (P = 0.03), and ribeye area (REA; P &lt; 0.01). Thirty-five percent (35%) of the Holsteins received a QG of Choice or above while 74% of crossbreds graded USDA Choice or above (P = 0.01). However, 75% of Holsteins were YG 2 or lower while only 45% of crossbreds achieved YG 2 or less (P = 0.05). There was no improvement in efficiency when crossbreds were compared to Holsteins; however, carcasses from crossbreds were more likely to grade USDA Choice or above while yielding greater REA and backfat than Holsteins.
