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. 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.

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 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

Daily Gain

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.

Background: Due to the resistance that various pathogens have developed to the unplanned use of antibiotic growth promoters (AGPs) and the risk to consumers health that this implies, AGPs could be replaced by natural products such as plants, essential oils or extracts. The current study was aimed to investigate the effects of a feed additive based on papaveraceae roots and nanoclays (Sangromix 10x®) on broiler performance. Methods: One hundred and twenty Cobb broilers one d old, were randomly assigned to a diet without additive or with additive at 20 g/t during 49 d. Broilers had free access to concentrate and fresh water and were weighed daily. Feed intake and body weight was measured daily and where used to estimate average daily gain and feed conversion ratio. Result: Broilers that received Sangromix 10x®, had higher final body weight, total gain, average daily gain and better feed conversion value as compared with broilers with no additive. The additive did not affect feed intake. The inclusion of Sangromix 10x® increased final body weight and improved feed conversion value and it can be concluded that is an efficient alternative for broiler production. Nevertheless, further research is required to determine their effect on meat and carcass quality, internal organs and blood biochemistry.

Shorthorn cows were confined year-round using three types of shelter (an enclosed barn, IN; a barn with free access to an outside yard, IN-OUT; and outside pens with only windbreak fences for shelter, OUT) and two types of feed (hay and grass silage) provided at three levels (ad libitum, L1 or 75%, L2 or 50%, L3, of ad libitum) until late pregnancy, after which all were fed their respective roughage ad libitum until late August weaning. No interactions were found among years, degree of shelter and feed levels. The average daily intake for hay and the corresponding average daily gain were greater (all differences cited were significant, P < 0.05) than those for silage. The daily intake and weight loss of the OUT cows were greater than those of the IN and IN-OUT cows. All differences among feed levels for daily intake and weight change were significant. Calves of dams fed hay were heavier at birth and grew more quickly. OUT calves were heavier than IN calves at birth, but their daily gain to weaning was considerably less than either IN or IN-OUT calves. Feed levels did not influence calf birth weight, but L1 calves gained more to weaning than L2 and L3 calves. Pregnancy percentages for IN cows were 91.7 (L1), 91.7 (L2) and 75.0 (L3); IN-OUT 88.9, 88.9 and 86.1 and OUT 88.9, 80.6 and 58.3. The general condition of OUT cows, especially those on L3 diet, was poor.

Twelve adult (10 months old) castrated Korean black goats, with an average initial body weight of 24.98 ± 3.7 kg, were used in this experiment to determine their maintenance energy requirements. Dry matter intakes (g/d, p = 0.945) were not affected by energy levels, but metabolic energy intake (kcal/d, p < 0.002) and average daily gain (g/d, p < 0.001) were significantly increased at higher energy levels. Nutrient digestibility was similar in the treatments, but crude fat digestibility increased with the addition of protective fat powder (p = 0.001). The energy required for fattening the castrated Korean black goats was estimated using the correlation between metabolic energy intake per dietary body weight and average daily gain per dietary body weight. The Y-axis intercept value was calculated to be 108.76 kcal/kg BW0.75 (p < 0.05, r2 = 0.6036), which was the metabolic energy requirement for maintaining the lives of the fattening Korean black goats. The estimated energy requirements of the black goat can improve specification techniques, such as the energy level and the amount of feed supply required for domestic black goats.

Abstract This research evaluated the effects of ensiled edamame soybean processing waste on ruminant intake and total tract digestibility. Waste from processing stored edamame was obtained (3 trips) and wilted (28%, 25%, and 37% DM), then treated with or without inoculant (Lactobacillus buchneri) and ensiled in 167 L plastic barrels (2 or 3 barrels/treatment from each trip) for 72 (Trip 1) or 69 (Trip 2 and 3) days. Pregnant ewes (n = 18; body weight = 55.5 ± 1.2 kg; 2 to 3 years old) were blocked by body weight and assigned randomly within a block to treatments within a trip, then each ewe was assigned to a barrel of silage. Ewes were housed individually in 1 × 1.5-m pens and offered silage for a 10-day adaptation period followed by 7 days of total feces and urine collection. Ewes were offered silage to allow for 10% orts and were offered 0.2% of their body weight of soyhulls and 32 g of mineral supplement/day to meet their predicted nutrient requirements for gestating ewes. Ewes consumed 1,616 ± 54 g DM/day (X ± SEM) or 2.9 ± 0.12% of their body weight and there was no effect (P ≥ 0.85) of inoculant treatment on DM intake (g/day or % of body weight). Dry matter digestibility was not affected (P = 0.98) by inoculant and averaged 55.7 ± 0.66%. Ewe average daily gain for the 17-day trial tended to be greater (P = 0.08) for the ewes offered the silage without inoculant (0.18 vs. 0.04 kg/d). Ensiling edamame processing waste yielded a feed that ewes consumed in adequate amounts to maintain their body weights over 17 days when also supplemented with soyhulls. The addition of silage inoculant had minimal effects on intake, digestibility, or ewe body weight change.

Abstract This study applied a chemical isotope labeling/liquid chromatography mass spectrometry-based metabolomics technique to determine differences in plasma metabolites containing amine/phenol and carbonyl chemical groups in beef steers with divergent average daily gain (ADG). Thirty-eight Angus crossbred beef steers (21 d post-weaning; 210 ± 12 kg of BW) from a single source were housed in individual slatted floor pens and were fed the same total mixed ration (CP = 14.5% and NEg = 1.10 Mcal/kg) ad libitum for 42 d with free access to water. After 42 days of feeding, the steers were divided into two groups of lowest ADG (LF: n = 8) and highest (HF: n = 8) ADG. Blood samples were taken from both LF and HF steers and were immediately centrifuged to harvest the plasma. The average daily DM intake of the steers in LF and HF were 6.08 kg ± 0.57 and 6.04 kg ± 0.42, respectively, and was similar between the two groups (P = 0.72). The ADG of LF (0.99 kg ± 0.23) was lower (P = 0.01) than that of HF (1.63 kg ± 0.20). A total number of 42 carbonyl-containing metabolites and 229 amine/phenol-containing metabolites were identified in the plasma samples of both groups. No alteration in carbonyl-metabolome was detected. Ten metabolites including 4,6-dihydroxyquinoline, prolyl-valine, prolyl-leucine, prolyl-isoleucine, L-formylkynurenine, pyrocatechol, and histidine were greater in HF steers whereas 8 metabolites including arginine, phenylalanine, guanidoacetic acid, and aspartyl-threonine were greater in LF steers. This study demonstrated that beef steers with divergent ADG had altered plasma amine/phenol metabolome. Notably, plasma concentrations of dipeptides containing branched chain amino acid residues (prolyl-valine, prolyl-leucine, prolyl-isoleucine) and metabolites with anti-inflammatory and reactive oxygen-scavenging properties (4,6-dihydroxyquinoline and L-formylkynurenine) were greater in steers with high ADG.
