The aim of the present study was to evaluate the effect of replacing corn grain with citrus pulp (CSP) in the starter concentrate on performance and metabolism of dairy calves. Twenty-four individually housed Holstein calves were blocked according to birth date and weight and fed one of the following concentrates: (1) concentrate containing 64% corn and 0% CSP (0CSP); (2) concentrate containing 32% corn and 32% CSP (32CSP); and (3) concentrate containing 0% corn and 64% CSP (64CSP). Animals were fed 4 L of milk replacer daily (20% crude protein, 16% ether extract) divided in two meals (at 0700 hours and 1800 hours). The starter feed and water were provided ad libitum. Starter intake and faecal score were monitored daily. Bodyweight and measurements (withers height, hip width and heart girth) were recorded weekly. Blood samples were collected weekly, and ruminal fluid samples at 4, 6 and 8 weeks of age, 2 h after the morning feeding. After 8 weeks, animals were harvested to evaluate the development of the proximal digestive tract. Concentrate composition had no effect (P > 0.05) on concentrate intake, weight gain, bodyweight, body measurements, and faecal score. However, there was a lower concentration of ruminal butyrate (P < 0.05) in animals receiving 0CSP than in those fed the starter containing CSP. The 0CSP concentrate resulted in a lower (P < 0.05) total weight of the proximal digestive tract, weight of the reticulum–rumen and weight of the omasum than did the other concentrates. The length of the rumen papillae was the greatest (P < 0.05) in 32CSP-fed animals. However, papillae area in animals fed 32CSP concentrate was larger (P < 0.05) than that in 0CSP- and 64CSP-fed animals, with no difference observed between these latter two treatments. However, 0CSP-fed animals showed a higher proportion of abomasum than did the animals fed 32CSP and 64CSP concentrates. The replacement of 50% or 100% of corn by CSP in the starter feed of dairy calves did not affect performance and probably contributed to the better development of the proximal digestive tract.

This study aimed to evaluate the performance and metabolic changes in dairy calves supplemented with lysine and methionine in milk replacer (MR) or starter concentrate (SC). Male Holstein calves (n = 45) were blocked and distributed in Control without supplementation (1) and; Lysine and Methionine supplementation to achieve an intake of 17 and 5.3 g/d in the SC (2) and to achieve of 17 and 5.3 g/d in the MR (3). MR was fed (6 L/d) until the 8th week of life when weaning occurred. Calves were followed until the 10th week of age. Feed intake was measured daily. Weight and body measurements were registered weekly. Blood samples were collected biweekly to evaluate the intermediate metabolism. The AA supplementation resulted in lower body weight at weaning and week 10. Calves fed SC Lys:Met had lower SC intake and lower total feed intake at weaning when compared to control. Calves fed control had higher heart girth, hip-width, and plasma glucose concentration. The supplementation with Lys and Met did not benefit dairy calves’ performance nor metabolism in this study. Supplementation through the MR was more efficient than SC to result in adequate daily intakes of AA. Further studies are needed to understand the negative effects of AA on calf starter intake.

This study aimed to investigate various levels of crude protein (CP) in starter diets and their supplementation with amino acids (AAs) on efficiency, health, and serum metabolites of dairy calves. Ninety-six newborn Holstein calves were allocated to eight treatments, namely T1) 18% CP unsupplemented starter, T2) T1 supplemented with additional 20% methionine, T3) T1 with additional 20% lysine and 20% methionine, T4) T1 with additional 20% lysine, T5) 22% CP unsupplemented starter, T6) T5 supplemented with additional 20% methionine, T7) T5 supplemented with additional 20% lysine and 20% methionine, and T8) T5 supplemented with additional 20% lysine. Consumption of the starter was not influenced by the level of CP. Calves that received the unsupplemented 22% CP starter had higher average daily gain (ADG) and final weight. But no significant differences among diets were found in feed efficiency. Skeletal growth did not exhibit a clear trend. Calves that received T3 had fewer bouts of diarrhea and reduced body temperature. However, there were no significant dietary effects on immunoglobin G (IgG) or total protein concentration in blood. T1–T3 decreased serum urea concentration. Thus, use of T3 resulted in an improved amino acid balance, and was less expensive than the 22% CP starter.Keywords: amino acid, feed intake, immunity, pre-ruminant calf

Abstract A blend of essential oils (EO) and a prebiotic were combined (EOC) to formulate a colostrum-based liquid birth supplement and a separate feeding supplement (Start Strong and Stay Strong, Ralco Inc., Marshall, MN). These products were designed to promote immunity and stimulate appetite to diminish health challenges and stresses experienced by newborn calves. The hypothesis was that calves supplemented with an oral dose of liquid EOC at birth (10-mL aliquot at birth and 10 mL at 12 h of age) when fed the EOC feeding supplement would result in improved growth performance, health, and immunity. The objective was to determine if an additional feeding of liquid EOC at birth in combination with EOC in the milk replacer (MR) would allow calves to demonstrate improved growth, health, and immunity compare with calves only offered EO in MR. Sixty-one Holstein calves (18 males and 43 females) from a commercial dairy operation were blocked by birth date and randomly assigned to 1 of 3 treatments. Treatments were 1) Control (CON): a 24% crude protein (CP):20% fat (as-fed basis) MR; 2) EP: a 24:20 MR with EOC mixed at 1.25 g/d; or 3) EPC: a 24:20 MR with EOC mixed at 1.25 g/d in addition to calves receiving one 10-mL oral dose of liquid EOC at birth and 10 mL again at 12 h. The 24:20 MR was fed via bucket 2 times per day at a rate of 0.57 kg/calf daily for 14 d, increased to 0.85 kg/calf at 2 times per day until 35 d and was reduced to 0.43 kg at 1 time per day at 36 d to facilitate weaning after 42 d. Decoquinate was added to the MR at 41.6 mg/kg for coccidiosis control. Calves were housed in individual hutches bedded with straw with ad libitum access to a 20% CP-pelleted calf starter and water. All data were analyzed using PROC MIXED as a randomized complete block design. Calves in this study had similar (P &gt; 0.10) average daily gains, body weight, and growth measurements. Calves fed EPC had significantly (P &lt; 0.05) higher IgA titers on day 0 of the trial compared with calves fed EP or CON, which was expected as calves were supplemented with liquid EOC at birth and 12 h later demonstrating an increase in immune response. The use of a liquid EOC product being administrated after birth can improve IgA titers to improve the immune status of the new born calf to fight off potential diseases and pathogens. A formulation error resulted in the EOC being fed at half the rate of the previous experiment of 2.5 g/d, which appears to be below an efficacious dosage.

Abstract The objective of this study was to evaluate the effect of whole flint corn grain or tropical grass hay free choice, as a fiber source in the diet, on the performance, ruminal and intestinal development of Holstein dairy calves. Forty-two Holstein calves were used in a randomized block design, considering sex, birth date and weight at 21 days of age (48.7 ± 0.82 kg), when the study started. Three solid diets were compared: 1) SC: starter concentrate only (24% CP, 14% NDF, 47% NFC); 2) SCH: starter concentrate, with free access to chopped Tifton-85 hay; and 3) SCW: starter concentrate with free access to whole flint corn grain. Animals were fed with 6 L/d until d 21, and then 4L/d of whole milk until gradual weaning at d 56. At weaning, 12 animals were randomly selected to be slaughtered to evaluate the weight of forestomach compartments and rumen and intestine morphometrics. Data were analyzed using the GLM or MIXED (repeated measures) procedure of SAS, and the means were compared using Tukey test (P ≤ 0.05). The SCH diet increased the total DMI (P = 0.01) and ADG (P = 0.01). Calves fed with SCH diet presented higher total proximal digestive tract weight (kg; P &lt; 0.01). The empty reticulum-rumen weight was higher in calves fed the SCH diet (P = 0.03). The papillae area was higher in calves fed with SCH diet (P = 0.05). The depth of the crypts and the number of goblet cells from the duodenum and cecum were not affected by diets; however, the duodenum villus height was higher for animals that received SCH (P = 0.02). The tropical grass hay supplementation in the diet improved performance, ruminal and intestinal development. The whole flint corn grain do not play a fiber role for dairy calves.

ABSTRACTObjective. To evaluate the effect of three energy sources on the intake, total apparent digestibility and excretion of nutrients in cattle diet. Materials and methods. Six ruminally cannulated cows (730 ± 70 kg) were distributed into three treatments in a replicated 3x3 Latin square experimental design, where: (I) Control: Low ether extract diet (3.50% EE); (II) Soybean: High ether extract diet (5.30% EE) with inclusion of 15% soybean and (III) Citrus pulp: Low ether extract diet (3.00% EE) and high pectin involvement with inclusion of 15% citrus pulp. To determine the digestibility of DM and its fractions, chromic oxide was used as a marker. Nutrient excretion was calculated from the digestibility coefficient of each fraction. Results. The soybean treatment reduced (p<0.05) dry matter, crude protein, nitrogen-free extract and organic matter intake and increased ether extract intake. There was no effect (p>0.05) of the energy source on the digestibility coefficients of DM, CP, NDF, EE, NFE or OM. The TDN value was higher for the soybean treatment. The excretion of DM, NFE and OM was lower (p<0.05) for the soybean treatment. All energy sources influenced the excretion of crude protein. Conclusions. The energy sources used did not affect the digestibility of the diets and are indicated as high potential sources to be used in cattle.

The effects of butyrate supplementation in diets of calves are inconsistent in the literature. Fifty-one Holstein calves (45.7 ± 5.8 kg of bodyweight and 11.8 ± 3.1 days of age; mean ± s.d.) were randomly allocated to three treatments to assess the effects of supplementing the milk replacer at 0.3% dry matter with butyrate in the form of sodium butyrate or tributyrin compared with no supplementation (CTR). Calves were fed 4 L/day of milk replacer (25% crude protein and 19.2% ether extract) and starter feed (20% crude protein and 3.8% ether extract) ad libitum over a period of 6 weeks. Individual intake was measured daily and bodyweight and blood β-hydroxybutyrate, glucose-like peptide-1, glucose and insulin were measured fortnightly. A glucose tolerance test was performed on Days 0 and 35 of the study. No effects of butyrate supplementation were found on starter and total dry matter intake. CTR calves had greater average daily gain than tributyrin calves. CTR calves tended to have greater final bodyweight than tributyrin and sodium butyrate calves. Gain : feed ratio tended to be greater for CTR calves. There were no differences in plasma glucose, insulin, β-hydroxybutyrate and glucose-like peptide-1 concentrations throughout among treatments the study. During the glucose tolerance test, no differences on insulin sensitivity were found among treatments. In conclusion, no apparent advantages of supplementing milk replacer with sodium butyrate or tributyrin were found on performance and glucose metabolism in calves.

This work was conducted with the objective to evaluate the effect of vermicompost application on chemical characteristics, energetic parameters and amino acids prof ile of hybrid race corn grain cultivated under open-f ield and rained conditions. The experiment was accomplished under a randomized complete design with three repetitions. Three treatments were evaluated: 1) Maize after inoculation with a commercial mycorrhizal arbuscular fungi mixture (Tec Myc 60®) plus vermicompost (V+M); vermicompost (V) and chemical fertilization (CF). Starch content in grain was 1.9% higher in V+M treatment in comparison with chemical, whereas crude protein, ether extract, crude f iber, acid detergent f iber, neutral detergent f iber, total phosphorous and phytic phosphorous were not different between treatments. Energetic parameters were not different between three treatments. 17 amino acids were evaluated of wich only tryptophan, leucine, valine, histidine and aspartic acid were higher in CF and V treatments in comparison with V+M treatment. In conclusion, it is possible to cultivate maize using vermicompost as fertilizer because chemical characteristics, energetic parameters and amino acids prof ile in maize grain were not affected compared with the maize cultivated with vermicompost added with biofertilizers (V+M) or with corn cultivated with chemical fertilizers (CF).

The objective of this experiment was to evaluate the effects of simultaneous using heat-treated corn grain as basic energy source and heat treated whole soybeans as protein source, in diet for calves 60-120 days old. The main predicted effects were improved energy and nutrients utilization efficiency and production performances of calves at this age. Thirty-six weaned Holstein calves were used, there were three treatments using different concentrates, formulated as: concentrate with micronized corn grain and extruded whole soybeans (KTT); concentrate with non-treated corn grain and soybean meal (KTN); concentrate with non-treated corn grain and extruded whole soybeans (KS). The marked effects of simultaneous use of heat-treated corn grain and whole soybeans were determined for feed efficiency (feed conversion ratio, FCR was 6,2% higher for calves on KTT than on KTN and 4,3% higher than on KS treatment). Efficiency of energy utilization (MJ ME/kg of gain) was better for calves on diet with KTT concentrate (5.8 % and 5.3% lower efficiency of metabolic energy utilization for KTN and KS treatment respectively). Consumed crude protein was better utilized for growth by calves on KTT diets, than other two treatments (10.8 % more CP/kg of growth for KTN, and 7.5% more for KS).

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.
