Reconstituted Milk

The present experiment was carried out to assess the effects of reconstituted milk (RM), acidified reconstituted milk (ARM), and acidified fresh milk (AFM) on growth performance, diarrhea rate, and hematological parameters of preweaning dairy calves. For this purpose, a total of 27 Holstein female calves (one month of age) with initial body weight of (67.46 ± 4.08) kg were divided into three groups in such a way that each group contained nine calves. Calves were housed individually, and starter was offered ad libitum to each calf. The dietary treatments were RM, ARM, and AFM. The highest milk intake was observed in calves receiving AFM as compared to other treatments (p < 0.01). Calves fed AFM had more feed intake than those fed ARM and RM (p < 0.01). Feed efficiency was significantly lower for calves offered ARM than those offered RM and AFM (p < 0.01). A lower withers height growth was found for calves fed RM than those fed ARM and AFM (p <0.05). Diarrhea rate and white blood cell (WBC) and lymphocytes (LYM) counts were greater for calves fed RM than those fed ARM and AFM (p < 0.05). These findings suggested that ARM and AFM had positive effects on growth performance and health status of the preweaning dairy calves.

Abstract This study investigated the interactive effects of Zn sources, Cu sources and phytase on growth performance in nursery pigs. A total of 288 weaning barrows (BW = 5.71 ± 0.81 kg), blocked by initial body weight, were randomly allotted to 1 of 8 dietary treatments, with 9 pens per treatment and 4 pigs per pen. The 8 dietary treatments were arranged in 2 × 2 × 2 factorial design, with 2 Zn sources [2000 ppm Zn from ZnO during phase 1 (d 1 to 14) and 2 (d 15 to 28), and 100 ppm Zn from ZnO during phase 3 (d 29 to 42); 100 ppm Zn from Zn methionine hydroxy analogue chelate (Zn-MHAC, MINTREX® Zn, Novus International Inc., St. Charles, MO) during phase 1 to 3], 2 Cu sources [150 ppm Cu from CuSO4 or Cu-MHAC (MINTREX® Cu) during phase 1, and 80 ppm Cu from CuSO4 or Cu-MHAC during phase 2 and 3], and 2 phytase inclusion levels (0, 500 FTU/kg). Results showed that there were no differences (P > 0.10) between ZnO and Zn-MHAC groups in terms of growth performance during the entire nursery period. Compared with CuSO4, Cu-MHAC tended to increase ADG (P = 0.07) and G:F (P = 0.08) during the entire nursery period. There tended to be an interaction (P = 0.09) between Cu sources and phytase on G:F during phase 2. Specifically, without phytase supplementation, there was no difference (P = 0.63) on G:F during phase 2 between Cu-MHAC and CuSO4, whereas with phytase supplementation, Cu-MHAC increased G:F during phase 2 (P = 0.05) compared with CuSO4. In conclusion, Zn-MHAC supplementation at 100 ppm could replace pharmacological level of ZnO without affecting growth performance. Cu-MHAC could improve growth performance compared with CuSO4. Cu-MHAC exerted synergistic effect with phytase on improving feed efficiency.

Background: Maoberry (Antidesma sp.) pomace (MP) is a waste product and therefore, it is important to exploit this resource as a feedstuff for animals. Hence, the current investigation is aimed to evaluate the effect of dietary supplementation of MP on growth performance, blood parameters, carcass quality and intestinal histology in broilers.Methods: 288 male (Ross 308), 1-day-old broilers were individually weighed and steel wing tagged before allocation to one of 24 floor pens (12 birds/pen). All birds received the same standard starter diet (7-21 d old) and finisher diet (22-42 d old) to conform with NRC (1994). After week one, six dietary treatments were provided, which contained five different maoberry (Antidesma sp.) pomace or MP sources: 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5%.Result: At 42 d, broiler fed 0.1, 0.2, 0.3, 0.4 and 0.5% MP had increased feed efficiency (FE) when compared with broilers on basal diets. Dressing and breast percentages were significantly increased across groups. Broilers fed MP had significantly (P less than 0.05) increased epithelial cell areas and cellular mitosis levels. Supplementing dietary MP exerted positive effects on FE and intestinal histology as they were significantly (P less than 0.05) increased in MP fed birds.

Abstract The objective of this experiment was to investigate dietary supplementation of oligosaccharide-based polymer on growth performance, diarrhea, and fecal β-hemolytic coliforms of weaned pigs experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Forty-eight pigs (7.23 ± 1.11 kg BW) were individually housed in disease containment rooms and randomly allotted to one of four treatments with 12 replicate pigs per treatment. The four dietary treatments were a nursery basal diet (control), and 3 additional diets supplemented with 50 mg/kg Mecadox (AGP), 10 or 20 mg/kg of oligosaccharide-based polymer. The experiment lasted 18 d [7 d before and 11 d after the first inoculation (d 0)]. The doses of F18 E. coli inoculum were 1010 cfu/3 mL oral dose daily for 3 days. Growth performance was measured on d -7 to 0 before inoculation, and d 0 to 5 and 5 to 11 post-inoculation (PI). Diarrhea score (DS; 1, normal, to 5, watery diarrhea) was daily recorded for each pig. Fecal samples were collected on d 2, 5, 8, and 11 PI to test the percentage of β-hemolytic coliforms in total coliforms. All data were analyzed by ANOVA using the PROC MIXED of SAS with pig as the experimental unit. Inclusion of oligosaccharide-based polymer linearly increased (P &lt; 0.05) ADFI on d 0 to 5 PI, and feed efficiency on d 0 to 5 PI and d 5 to 11 PI (P = 0.07), compared with the control. Supplementation of AGP or oligosaccharide-based polymer reduced (P &lt; 0.01) frequency of diarrhea of pigs from d 0 to 11 PI. No differences were observed in overall growth performance and percentage of fecal β-hemolytic coliforms on d 8 PI among pigs in AGP and oligosaccharide-based polymer treatments. In conclusion, supplementation of oligosaccharide-based polymer enhanced feed efficiency and reduced diarrhea of weaned pigs infected with a pathogenic E. coli.

A 6 wk trial was conducted to evaluate the effects of nucleotide supplementation in improving performance, nutrient digestibility, and immune blood profiles so as to reduce foot-and-mouth disease (FMD) vaccine stress in growing pigs. A total of 120 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 25.76 ± 1.83 kg were used. Pigs were allocated to one of three treatments (eight pens per treatment; three barrows and two gilts per pen) based on BW and sex. Pigs were injected with FMD vaccine at 84 d of age (2 wk after experiment started). Dietary treatments consisted of (1) CON: corn–soybean-meal-based diet, (2) NUC1: CON + 0.5% nucleotide, and (3) NUC2: CON + 1.0% nucleotide. In the current study, the growth performance of gain:feed ratio (G:F), the apparent total tract digestibility of dry matter and nitrogen was linearly (P < 0.05) increased with the increasing level of nucleotide. After injection, the concentration of cortisol and epinephrine was decreased (P < 0.05) linearly in nucleotide treatments. In conclusion, nucleotide supplementation to FMD vaccinated pigs showed positive effects on improving performance, immune system health, and reducing vaccine stress in growing pigs.

The inclusion of straw in high concentrate total mixed rations (TMRs) of male fattening goats can provide the necessary fiber to prevent ruminal acidosis and maintain growth. The objective of this study was to evaluate the effects of the physical form (PF) of the diet (pelleted vs. conventional) and the straw level (SL) of wheat straw (WS) (15% versus 25%) in total mixed rations on feed intake, growth, total tract digestibility, and blood metabolites of fattening goats. Thirty-two male Beetal goats (27.4 ± 0.28 kg body weight (BW)) were divided randomly into the following four dietary treatments with a 2 × 2 factorial arrangement (n = 8/treatment): (1) CTMR15 (conventional TMR containing 15% WS), (2) CTMR25 (conventional TMR containing 25% WS), (3) PTMR15 (pelleted TMR containing 15% WS), and (4) PTMR25 (pelleted TMR containing 25% WS). Both conventional and pelleted 15% WS TMR had 33.7% neutral detergent fiber (NDF) and 19.3% acid detergent fiber (ADF), whereas in 25% WS TMR the NDF and ADF contents were 38.7% and 22.9%, respectively. The experimental diets were formulated to be iso-nitrogenous (crude protein (CP) = 15%). The dry matter intake (DMI) (1.265 vs. 1.044 kg/day) and average daily gain (ADG) (0.176 vs. 0.143 kg/day) were higher (p < 0.05) in pelleted vs. conventional TMR-fed goats. Irrespective of the PF of the TMR, the 15% WS-fed animals had greater (p < 0.05) DMI (1.206 vs. 1.102 kg/day) and ADG (0.172 vs. 0.144 kg) when compared to those fed on 25% WS diets. Furthermore, feed-to-gain ratio (F:G) was higher (p < 0.05) in the 25% WS-fed goats when compared with the 15% WS-fed animals. Digestibility coefficients, nitrogen balancing, hepatic enzymes, blood metabolites, and hematological parameters were similar (p > 0.05) across all treatments. In conclusion, feeding pelleted TMR with WS improved DMI and growth performance as compared to those fed conventional TMR, and 15% WS performed better than 25% WS without exerting any adverse effects on blood metabolites, liver enzymes, or hematological parameters.

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.

Dietary soluble fibre limits the incidence of epizootic rabbit enteropathy (ERE) and improves the energy and nitrogen balance in low-insoluble fibre diets, while high-insoluble fibre diets seem to favour ERE. This study assessed whether the positive effects of soluble fibre are influenced by the level of insoluble fibre. Four diets (2 × 2 factorial arrangement) were used with two levels of insoluble fibre (314 vs. 393 g/kg DM) and soluble fibre (87 vs. 128 g/kg DM), resulting in four diets with increasing total dietary fibre levels. Growth performance and chemical composition (body and carcass) (28–62 days of age), faecal digestibility (54–57 days of age), and jejunal morphometry functionality (39 days of age) were determined. Mortality was low (<1%) and treatments did not influence it. Insoluble and soluble fibre tended to reduce the growth rate (p ≤ 0.109), body protein, and fat accretion (p = 0.049 to 0.120), but only insoluble fibre impaired feed efficiency (p < 0.001). The efficiency of digestible energy used for growth was impaired with the increase of total dietary fibre (p = 0.027), while that of nitrogen remained majorly unaffected. In conclusion, in healthy rabbits, the increase of either insoluble or soluble fibre had no benefit.

Abstract A total of 1,215 pigs (L337×1050, PIC, Hendersonville, TN) were used in a 156-d wean-to-finish experiment. Pigs were weaned at 21 d of age and placed in pens based on initial body weight (BW) with 27 pigs/pen. There were three dietary treatments including a: 1) control; 2) pigs fed diets containing AviPlus (micro-encapsulated sorbic and citric acids and synthetic thymol and vanillin botanicals; Vetagro Inc., Chicago, IL) during the nursery and finisher phases; or 3) pigs fed AviPlus during the nursery but not the finishing phase. AviPlus was included at 2.72 kg/ton from d 0 to 21, 0.90 kg/ton from d 21 to 42, and 0.45 kg/ton from d 42 to 156. Thus, there were 15 control pens and 30 Aviplus pens in the nursery and 15 pens for the 3 treatments in the finisher phase. On d 42, pigs were transported as intact pens to the finishing facility. Data were analyzed as a RCBD with pen as experimental unit. For the overall nursery period (d 0 to 42), pigs fed AviPlus had improved (P &lt; 0.05) G:F, with no evidence of difference (P &gt; 0.05) for d 42 BW, ADG, or ADFI. For the overall finishing period (d 42 to 156) and overall experimental period (d 0 to 156), there was no evidence of difference (P &gt; 0.05) for BW, ADG, ADFI, or G:F. There was no evidence of difference (P &gt; 0.05) observed for mortality and removals during the nursery, finisher, or overall. In summary, providing AviPlus during the nursery improved nursery G:F, but there was no effect on overall wean-to-finish performance.

This study was conducted to evaluate the effects of dietary FVS supplementation on growth performance, nutrient digestibility, biochemical profile of serum and fecal short chain fatty acids (SCFAs) production in weaned piglets. In Exp.1, 150 weaned pigs (initial body weight: 6.89 ± 1.17 kg) were allotted to five dietary treatments. The treatment diets included a basal diet and four experimental diets supplemented with 2.5%, 5.0%, 7.5% and 10.0% FVS respectively. The animal trial lasted for 28 days. In Exp.2, 72 piglets (initial body weight: 8.20 ± 1.67 kg) were allotted to three dietary treatments. The treatment diets included a basal diet and two experimental diets supplemented with 1.5% and 3.0% FVS, respectively. The animal trial lasted for 56 days. The results showed that pigs fed dietary FVS with 3% or lower inclusion levels had no significant difference (p > 0.10) on growth performance compared with pigs fed the control diet during day 1–28 and day 1–56. Dietary FVS supplementation decreased the apparent total tract digestibility (ATTD) of nutrients on day 28, day 35 and day 56, but no significant changes (p > 0.05) of nutrient digestibility were observed on day 14. Although piglets fed diets with higher levels of FVS showed impaired growth performance and ATTD of nutrients, dietary FVS supplementation improved the fecal SCFA production, antioxidant capacity, interleukin-2 and growth hormone levels in serum, and reduced the harmful low-density lipoprotein levels in serum on day 56. In conclusion, as a promising alternative fibrous ingredient, FVS could be supplemented in diets of weaned piglets with a proportion under 3%.

Abstract Ninety steers (259.9 ± 36.18 kg BW) were used in a 56-d experiment to assess the effects of flavoring additives on feeding behavior, feed efficiency, growth performance, and temperament of newly arrived feedlot cattle. Steers were homogenously distributed by BW into six pens (15 head/pen) and pen was randomly assigned to one of 3 treatments (2 pens/treatment): a standard feedlot receiving diet (CT); or the same diet with a flavoring additive comprised of either sweeteners (SW) or a mix of basic tastes (MX) at 1 g/kg (Lucta SA, Barcelona, Spain). Pens were equipped with a feed intake monitoring system (Growsafe Systems, Airdrie, Canada), while BW and chute exit flight speed were measured bi-weekly during the study. Data were analyzed using a mixed-effects model accounting for repeated measures. There were multiple treatment × time interactions (P &lt; 0.05), where DMI per meal was greater in SW than CT and MX on wk 3 and 5, respectively, and in MX than CT and SW on wk 3 and 7, respectively. The number of visits to the feed bunk per day was greater in MX than CT on wk 2, it was greater in SW than MX on wk 4, and it was greater in CT than in MX and SW on wk 4, and wk 7 and 8, respectively. The eating rate was greater in SW than MX on wk 4 and 5 and greater than CT and on wk 4. Although the cumulative responses for DMI, ADG and feed efficiency (FE; kg BW/kg DM) were not significant (P &gt; 0.1), FE was greater in SW and MX than CT from 27 to 41 d. Despite these positive effects on FE, there was no feeding pattern associated with the inclusion of flavoring additives in the diet of receiving feedlot cattle.
