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 The positive effects of nucleotides (NU) supplementation in milk replacer has 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 following treatments: whole milk without any supplementation (NU0), whole milk + 0.5 g/d added NU to whole milk (NU0.5), and whole milk + 1 g/d added NU to whole milk (NU1). Calves were weaned at d 55 and stayed on study until d 75. Calves had free access to feed and water throughout the study. Calves fed all treatments were similar (P > 0.05) in dry matter intake (DMI) during the pre-weaning period, however increasing NU supplementation resulted in a linear (P < 0.05) increase in DMI during the post weaning period. Treatments did not affect body weight (BW) at the first and second month of study but final BW linearly increased as NU was added. Neither pre-weaning average daily gain nor post-weaning average daily gain were affected by treatments; accordingly, feed efficiency was similar among treatment groups.

The purpose of the current study was to determine the best method of delivery for glucocorticoid receptor agonist (GRA) treatment. A total of 167 Pig Improvement Company (PIC) piglets (body weight (BW) 7.35 ± 1.24 kg) were weaned at 25.0 ± 0.81 days of age and randomly assigned to 14 treatment groups based on a 2 × 7 factorial arrangement with sex (gilts vs. barrows), in-feed antibiotic (ANT; 110 mg/kg in-feed tylosin), repeated intramuscular (I.M.) injection of GRA (two injections, 0.2 mg/kg BW dexamethasone (DEX)), low dose in-feed GRA (LF, 2.5 mg/kg diet DEX ), high dose in-feed GRA (HF, 5 mg/kg diet DEX), low dose in-water GRA (LW, 0.8 mg/L DEX ), high dose in-water GRA (HW, 1.6 mg/L DEX ), and no treatment control (CON) as the main factors. Body weight and feed intake were measured daily from days 0 to 7 and weekly from days 7 to 28 post-weaning. The interaction effect for average daily gain (ADG) was significant with gilts performing better in the I.M., ANT, and LF groups (p = 0.05). All treatment groups, with the exception of the HW group, had a higher ADG than the CON group. Gilts in the I.M., LF, and HF groups had the highest ADG compared to other treatment groups (p ≤ 0.05). Sex and the interaction between sex and treatments had no effect on the gain-to-feed ratio (G:F; p ≥ 0.21). All treatment groups had a higher G:F than the CON group (p ≥ 0.04). These results suggest that the low-dose, in-feed GRA treatment is the best GRA delivery method and is a suitable alternative to in-feed sub-therapeutic antibiotics.

The effect of feeding barley-wheat-soya finisher, gestation and lactation diets containing (A) 1979 National Research Council (NRC) recommended calcium-phosphorus (Ca-P) levels or (B) 150% of NRC levels from 65 kg body weight (Bwt) on growth and reproduction was studied in two experiments using Lacombe (L) and Yorkshire (Y) gilts. The number of gilts used were 299 (148 L + 151 Y) and 107 (53 Y + 54 Y) in exp. 1 and 216 (106 L + 110 Y) and 101 (49 L + 52 Y) in exp. 2 during finishing and gestation-lactation periods, respectively. The reproductive performance during second parity was measured only in exp. 2 using 85 (36 L + 49 Y) primiparous sows. All pigs were housed in confinement except during breeding and gestation, when they were housed in outside dirt-lot pens. Average daily gain, feed intake, and feed conversion were similar for gilts fed finisher diets A or B in both experiments. In exp. 1, both L and Y gilts fed gestation diet B had more (P < 0.05) total (9.5 ± 0.3 vs. 8.6 ± 0.3) and live pigs (9.2 ± 0.3 vs. 8.2 ± 0.3) born and weaned (7.7 ± 0.3 vs 6.9 ± 0.2) with lower piglet weight gains at 3 wk (3.5 ± 0.1 vs. 3.9 ± 0.1 kg) and 5 wk (6.9 ± 0.2 vs. 7.5 ± 0.2 kg) when compared to gestation diet A group. These differences were not significant in exp. 2. Higher dietary Ca-P levels elevated the serum P during both gestation (7.3 ± 0.1 vs. 7.0 ± 0.1 mg/dL) and lactation (6.2 ± 0.1 vs. 5.9 ± 0.1 mg/dL) periods in exp. 1 but not in exp. 2. The changes in body weight during gestation and lactation, piglet birth weights, and weaning to estrus interval were similar for both treatment groups. These results indicated that the 1979 NRC recommended dietary Ca-P levels may be adequate to support the maximum growth and reproduction in gilts during finishing and lactation but are too low for gestation.

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.

The present experiment was carried out on farmers’ goats in their sheds in Rayale village of Kavre district for 150 days. Eighteen khari goats (both male and female), 8-12 months old and having similar body weight were randomly divided into three groups comprising of six individuals in each group. Three types of rations were formulated for the experimental goats. Feed intake by experimental goats in terms of green and dry matter was significantly different (P&lt;0.05) between the treatment groups. Growth rate of the goats fed with top dressed maize stover (treatment 2) was higher than the treatment 3 (seasonal fodder adlib + 200 g concentrate mixture) and treatment 1 (1/2 maize stover silage + seasonal fodder adlib + 200 g concentrate mixture). The lowest average daily gain (ADG) was found in treatment 3 where goats were fed conventional fodder and grasses supplemented with concentrate (18.4 g) followed by treatment 1 (24.6 g). <i> Nepal Journal of Science and Technology </i> Vol. 7 2006

Abstract A total of 18 sows (Landrace × Yorkshire) with an average body weight of (within 24 h after farrowing) were used for a 5- week experiment to determine the effects of varying dietary Valine, Lysine (V:L) ratios on performance and fecal score in lactating sows and litters. Sows were raised in individual pens, and assigned to one of three experimental diets consisting different concentration of Valine, Lysine ratios (0.83%, 0.85% and 0.88%). sows body weight was significantly improved by 0.85% valine and lysine ratio compared to 0.85% and 0.88%. However, no significant difference were observed on sows body weight loss, back fat thickness, average daily feed intake and days to return to estrus of sows during the three experiment period. In addition, growth performance of piglet weaning weight were significantly improved by 0.85% valine and lysine ratio compared to 0.85% and 0.88%. Morever, piglet average daily gain was significantly increased 0.88% valine and lysine ratio compared to 0.83% and 0.85%. The three dietary treatments had a significant differences (P&gt;0.05) on fecal score of sows, farrowing and 14 d old age piglets were significantly observed by valine and lisiune ratio. In conclusion, Valine, Lysine had no positive effects on the fecal score of sows and litter during lactation and also no positive effect on gut and its microflora.

Abstract The objective of the present study was to evaluate the effects of different ratios of L-Arginine and lysine on the performance of sows and their piglets. A total of 12 (Landrace×Yorkshire) sows, with an average parity of 2.3 (from 1 to 4), were subjected to 3 treatments with 4 sows per treatment. Treatments were as follows: 1) CON, Basal diet (L-arginine: Lysine= 0.95), 2) TRT1, CON + Arginine (A: L = 1), and 3) TRT2, CON + Arginine (A: L = 1.05). The supplementation of 1.05 A: L showed reduction in body weight loss after farrowing (linear, P = 0.0105), at weaning (linear, P = 0.0492), and increased the back-fat thickness loss after farrowing (0.00498) and at weaning (0.0204). Dietary supplementation of 1.05 A: L increased (linear, P = 0.0226) body weight of piglets at weaning. In addition, dietary supplementation of L-Arginine tended to increase (linear, P = 0.0103) the average daily gain (ADG) of piglets at weaning. In conclusion, dietary supplementation with L-arginine (A: L = 1.05) exerted positive effects on some of the reproductive performance parameters in sows and growth performance in suckling piglets. These findings may provide an insight into a new nutritional strategy for sows.

This experiment aims to study the effects of dietary fat level during the suckling period on growth<br />performance and meat characteristics in twin lambs. Thirty pairs of male twin Hu lambs were divided into two<br />groups, namely high fat (HF) and normal fat (NF). Lambs in HF group were fed milk replacer and starter containing<br />26.89% and 5.07% of fat, whereas those in NF group, were fed milk replacer and starter containing 15.15% and<br />2.80% of fat, respectively, from eight to 60 days of age. From 60 to 120 days of age, all lambs were fed a starter feed<br />containing 2.80% fat. The results showed that lambs fed HF diet had higher body weight (12.78 kg versus 11.63 kg,<br />P = 0.020), average daily gain (162.4 g/day versus 141.1 g/day, P = 0.019), apparent digestibility of organic matter<br />(P = 0.018) and gross energy (P &lt; 0.001). No difference was observed between HF and NF group in slaughter performance<br />during eight to 60 days of age. Lambs fed HF diet had higher body weight at 120 days of age (P = 0.035).<br />However, no difference was observed in nutrient digestibility, slaughter performance or meat quality at 120 days<br />of age. In summary, HF diet in the suckling period showed long-lasting beneficial effects on the growth performance

This research communication describes relationships between pre-weaning average daily gain (ADG) and dam parity with future productivity of dairy calves. Higher ADG before weaning has been shown to be related to greater milk production in the first lactation of Holstein calves fed milk replacer. However, data is limited on the relationship between pre-weaning ADG and first lactation performance of Holstein calves fed whole milk. Data of three hundred and thirty-two Holstein calves from 35 primiparous and 297 multiparous cows was investigated to evaluate the relationship between the dam parity and pre-weaning ADG with the first lactation performance. Results indicated that birth (P < 0·01), and weaning body weight (P < 0·001) were greater in calves born from multiparous cows. Neither 305 d milk production nor pre-weaning ADG differed significantly between calves born to primiparous or multiparous cows, although milk yield tended to be higher in the former and ADG higher in the latter. Correlations between 305 d milk yield and pre-weaning ADG, dam parity and birth body weight were low and non-significant, although there was a tendency for a positive correlation between ADG and milk yield.

In a study that lasted for 120 days, 20 weaned Yankasa ram lambs aged 6 months and weighing between 10.5 and 14.5kg with an average of 12.75kg were offered a basal Digitaria smutsii hay diet at 2% of body weight. This was supplemented with a concentrate mixture made to supply 14.6% crude protein and 2.6 Mcal ME per kg and offered to treatment groups A, B, C and D at 1, 2, 3, and 4% of body weight respectively. There were five replicates and the animals were fed individually. Results indicated that the differences in Average Daily Gain was significant (P<0.05) between all the treatments; the value increased with increased level of feeding. The cost of effecting one unit of live weight increase was not significantly different (P<0.05) between treatments, A, B, and C, but it was significantly lower (P<0.05) than for treatment D. The low growth response of lambs fed the concentrate at 1% of body weight and the higher cost per unit gain of lambs offered the supplement at 4% of body weight suggested that concentrate supplementation at 2 and 3% of body weight was adequate for optimum liveweight gains in the Yankasa sheep breed.
