Milk Feeding

Twelve Large White × Landrace sows nursing litters of 6 boars and 6 gilts were used in this study. Six litters suckled the sow only, whereas the other 6 litters received supplemental liquid skim milk (200 g/L) ad libitum from Day 10 until Day 20. On Day 20 the 4 heaviest pigs of each sex were allocated to 2 pairs and were weaned. Each pair was offered either pelleted or pelleted plus liquid feed. For the first 2 days post-weaning, each pair of liquid-supplemented pigs received liquid skim milk (250 g/L). On Day 23, pelleted feed was added to the milk. The ratio of liquid to pelleted feed was adjusted daily until, on Day 28, pigs were provided with pelleted feed only until 41 days of age. Supplemental skim milk increased growth (223 v. 291 g/day, P < 0.001) between Days 10 and 20 of age so that by weaning supplemented pigs were 10% (6.13 v. 6.74 kg, P = 0.038) heavier than unsupplemented pigs. Skim milk intake increased linearly from 190 to 600 g/day per pig over the 10 days of supplementation. Supplemental milk feeding did not alter sow liveweight change (−31.9 v. −30.3 kg for sows nursing litters with and without supplementation, respectively, P = 0.894) or change in P2 backfat thickness (−5.3 v. −4.2 mm, P = 0.279) between farrowing and Day 20 of age. Pigs weaned onto skim milk and pellets ate more (257 v. 30 g dry matter (DM)/day, P < 0.001) and grew better (213 v. −151 g/day, P < 0.001) over the first 2 days post-weaning than pigs weaned onto only pellets. Piglets provided with liquid feed after weaning continued to grow faster beyond Day 22, resulting in the benefit of weaning onto liquid feed being maintained until at least 41 days of age (14.1 v. 12.8 kg, P < 0.001). In conclusion, skim milk feeding before and after weaning can result in cumulative improvements in growth performance in the nursery.

Milk Feeding

The present study was conducted to assess the effects of pre-weaning probiotic treatments on growth performance of male Holstein calves. For experimental treatments, 20 male calves were divided into 2 groups as of control and treatment group. Control group calves were supplied with fresh milk daily in two meals without any growth promoting supplement. Together with fresh milk supply, treatment group calves were supplied with additional 2 g probiotics to their morning meal. Throughout 56-day milk-feeding period, live weights (LW) and feed consumptions (FC) of the calves were determined. As compared to the control group, probiotic-supplemented calves had 5.25% higher weaning live weight and 11.4% higher daily live weight gain (P less than 0.05). Probiotic-supplemented calves consumed 2% more feed than the control calves (P>0.05) and had 9.52% better feed conversion ratio than the control group calves (P less than 0.05). Probiotic supplementation did not affect blood biochemical parameters significantly (P less than 0.05), except ALT, triglyceride and iron levels (P less than 0.05). It was concluded that probiotic supplementation during milk-feeding period improved growth performance of experimental Holstein calves.

Abstract Gut health is critical for neonatal calves, and nutritional technologies are needed for disease and stress prevention. Previous work feeding Monensin (MON) in combination with a blend of essential oils and a proprietary cobalt source (EOC) blend had demonstrated improved calf gut health and growth performance. The objective was to evaluate MON and EOC alone or in combination on calf growth performance. Eighty (80) new born Holstein calves were randomly assigned to one of four treatments arranged in a 2 x 2 factorial (MON and EOC). Treatments were: 1) Control without MON or EOC added to the calf starter (CS); 2) MON: 50.8 mg/kg CS (Norvikon Biotechnology Co., Hunan, China); 3) EOC: 44.1 mg/kg CS (Rum-A-Fresh, Ralco Inc. Marshall, MN); 4) MON+EOC: MON and EOC added to CS. Calves were fed colostrum followed by whole milk through weaning at 42 d, while CS was fed ad libitum through the 70-d experimental period. The MON by EOC interaction was found to be nonsignificant (P &gt; 0.41) for growth performance. Calves fed without or with MON demonstrated similar (P &gt; 0.70) body weight (BW; 68.7 and 68.9 kg without and with MON, respectively), while calves fed EOC demonstrated greater (P &lt; 0.01) BW (67.3 and 70.4 kg without and with EOC, respectively) compared with calves fed without EOC. Calves fed a CS containing MON were similar (P &gt; 0.47) in ADG (0.88 and 0.91 kg/d) compared with calves fed without MON; however, calves fed a CS with EOC increased (P &lt; 0.01) ADG (0.84 and 0.95 kg/d) 13% through the 70 d experimental period compared with calves not fed EOC. These data demonstrate that EOC and MON fed in combination was not beneficial for enhancing growth performance, but that calf growth performance can be improved with EOC compared to MON.

Different Levels

Abstract Different levels and sources of NDF can modify the gastrointestinal microbiome. This study evaluated 18 Holstein calves housed in not-bedded suspended individual cages and fed one of three treatments: 22NDF - conventional starter containing 22% NDF (n = 7); 31NDF - starter with 31% NDF, replacing part of the corn by soybean hull (n = 6); and 22NDF+H - conventional starter with 22% NDF plus coast-cross hay ad libitum (n = 5). All animals received 4 L of milk replacer daily (24% CP; 18.5% fat; diluted to 12.5% solids), divided into two meals, being weaned at 8th week of age. After weaning, animals were housed in tropical shelters, fed with the respective solid diet and coast-cross hay ad libitum for all treatments. To evaluate the microbiome, ruminal fluid samples were collected using a modified Geishauser oral probe at weeks 2, 4, 6, 8 and 10, two hours after the morning feeding, and fecal samples were collected at birth (0) and at weeks 1, 2, 4, 8 and 10. The microbial community was determined by sequencing V3 and V4 region amplicons of the 16S rRNA gene that was amplified by PCR and sequenced by the Illumina MiSeq platform. Ruminal microbiome had no differences in diversity for the effects of weeks, treatments or interaction of both factors (Table 1). In feces, the diversity indices and evenness were higher for 22NDF+H when compared to 22NDF, with no difference for 31NDF. All indices were significantly affected by calves age. At birth, calves had the greatest diversity and richness. Week 1 and 2 had less evenness and diversity. Bacteroidota, Firmicutes_A and Firmicutes_C were the most abundant phylum in rumen and feces. The supply of hay was only effective in modifying the fecal microbiome of dairy calves, suggesting a resilience in the ruminal microbiome.

The objective of this study was to determine the effects of chlorogenic acid (CA) and bamboo charcoal particles activated by microwave (BCP) on performance, serum urea nitrogen and husbandry environment of broilers. The diets were devoid of antibiotic growth promoters (AGP). Two hundred and forty Avian broilers were allocated to a 2 × 2 factorial experiment involving two levels of CA (0 or 1000 mg CA/kg feed), and two levels of BCP supplementation (0 or 100 mg/kg feed). The diets and water were offered ad libitum. The growth performance and serum urea nitrogen was significantly increased when CA supplemented (P<0.05), while BCP significantly affects the ammonia concentration of the husbandry environment (P<0.05). These results indicate that CA and BCP combination can effectively improve the performance and husbandry environment.

Effect Of Feeding

A five-week study was conducted to determine the effect of feeding varying levels of S. cerevisiae on carcass and organ characteristics of finishing broilers. One hundred and twenty 4-weeks old broilers of cobb strain were randomly assigned to four treatments (T1 = 0.6 g Saccharomyces cerevisiae (SC) kg–1 diet; T2 = 0.8 g SC kg–1 diet; T3 = 1.0 g SC kg–1 diet and T4 = 0.0 g SC kg–1 diet) with 30 birds per treatment and replicated twice with 15 birds per replicate in a completely randomized design. Feed and water were provided ad libitum to the birds in a deep litter system. In the end, data on growth, carcass and organ indices generated from the study were analyzed using one-way analysis of variance (ANOVA). Results showed no significant difference (p > 0.05) among the treatments in the birds’ growth performance indices. However, significant differences (p < 0.05) were observed in the birds’ values for liver weight, heart weight, shank length and thigh length with birds in T3 recording highest values of 61.30 g, 16.93 g and 12.00 cm for liver weight, heart weight and thigh length, respectively. It was thus concluded that finishing broilers fed 1.0 g of S. cerevisiae had superior carcass and organ characteristics than birds on the control and lower levels of inclusion.
