An attempt was made to improve the digestibility of soy proteins (promine D) in milk replacers for young calves by supplementing the diets with pepsin and/or pancreatin preparations. Calves fed the basal soy milk replacer from 3 to 31 days of age had an average gain of 0.198 kg/day; those fed a skim powder control gained 0.443 kg/day. Supplementation of the basal soy milk replacer with 0.5% (of dry matter (DM)) pancreatin or 0.5% pepsin, or both treatments together, had a detrimental effect on calf performance, reducing gains to 0.106, 0.034 and −0.049 kg/day, respectively. Supplementation of soy replacer with these enzymes, separately or together, also reduced apparent digestibility of DM, N and lipid but had no effect on feed intakes.

The large utilization of coccidiostats in dairy herds has raised the question regards the best product to use, based on better animal performance. Sixty-four Holstein calves were randomly assigned to four treatments at 10 (±4) d of age to evaluate calf performance when fed approved coccidiostats available on the market in Arizona, USA. Calves received a dry calf starter without (control) or with one of the following coccidiostats: lasalocid, 30 mg kg-1; decoquinate, 19 mg kg-1; and monensin, 30 mg kg-1. Calves received 3.6 kg d-1 of a commercial 22% CP:20% fat milk replacer until 6 wk of age. Calves were offered starter "ad libitum" up to 2 kg d-1, and calves had free access to water throughout the trial. Alfalfa hay was offered "ad libitum" after weaning. Performance and dry matter intake (DMI) were monitored for 20 weeks and broken down in different periods of measurement (0-6, 7-12 and 13-20 weeks, respectively). Despite the lower dry matter intake and weight gain for females on monensin treatment during the whole period, differences among coccidiostats were seldom observed under the conditions of this study. Good calf management and the dry, hot climate of Arizona perhaps diminished the chances for subclinical and chronic disease appearance which negated potential differences and differences in calf performances.

AbstractThe morphological development of the sheep and the goat is different and this difference is manifested from early post-natal life. The main characteristic of kid goat carcasses is their low adipose tissue, and this is considered detrimental to quality. In an attempt to determine the nutritional causes of this, a study was performed with kid goats of the Granadina breed and lambs of the Segureña breed. Six kid goats and six lambs were slaughtered at birth, while a further eight kids and eight lambs were fed a milk replacer to satiety until the 60th day of life and slaughtered on the 61st day. Dry matter (DM) and metabolizable energy (ME) intakes and apparent digestibility of energy were determined in four balance periods between 8 and 60 days of life. From the intakes of ME and comparative slaughter data it was possible to calculate energy retention (ER), heat loss (HL) and energy retained as protein (ERp) and as fat (ERf) for kids and lambs. Kid goats showed a similar apparent digestibility of energy to lambs but had lower DM and ME intakes per kg metabolic body weight (M0·75) than lambs. For kids and lambs respectively these values were: 0·93 and 0·94; 45·4 and 50·1 g/kg M0·75 per day; 937 and 1033 kJ/kg M0·75 per day. Mean values for ER, HL, ERp and ERf rates were: 263, 674, 131 and 132 kJ/kg M0·75 per day for kid goats and, 343, 690, 132 and 211 kJ/kg M0·75 per day for lambs. Together with the different intake, kid goats showed a lower rate of ER and overall, a lower rate of ERf than lambs.

The purpose of this experiment was to formulate and evaluate milk replacer on the production performance of twin lambs from before weaning to one month after weaning. Three pairs of twin lambs aged two weeks with a body weight of 3.83 ± 0.4 kg were divided into two groups, each consisting of three lambs. The treatments applied were PSI = lamb given mother's milk and PMR = lamb given milk replacer. Pre-weaning dry matter consumption data were analyzed descriptively and other data were analyzed using the T-test. The results showed that the dry matter consumption lambs that were given milk replacers in pre-weaning was 164.18 ± 31.25 g/head/day with the largest proportion coming from milk replacers (61.4%). PSI group lambs had dry matter and energy consumption after weaning, daily gain before and after weaning, and body weight when weaned were significantly higher (P <0.05) than the PMR group lambs. However, the ratio of feed conversion and body weight at 90 days in the two groups of lamb were not significantly different. All lambs were healthy and no one died. It is concluded that formulated milk replacer provides production performance in lambs that are equivalent to lambs fed with mother's milk.

Forty male Holstein calves were divided into four groups; one group was offered whole milk and each of the others was given a different milk replacer. All calves were fed at 12% of body weight for 6 wk and a starter ration was fed free choice for the last 3 wk of the trial. Growth rate was 0.58, 0.32, 0.30, and 0.25 kg/day for whole milk and milk replacers B, C, and D, respectively, while the respective intake of calf starter was 0.23, 0.36, 0.34, and 0.38 kg/day of dry matter per calf per day. Feed conversions during the last 3 wk of the experiment were 1.15, 1.66, 1.45, and 1.65 kg of dry matter per kg of gain for whole milk and replacers B, C, and D, respectively. Blood hematocrit was higher for calves fed milk replacer B than for the other three treatments. Blood glucose levels were 123, 96, 107 and 101 mg percent for whole milk and milk replacers B, C, and D, respectively. The relationships between plasma glucose and blood urea nitrogen with growth rate and intake of calf starter were evaluated.

Alkali treatment to disperse a soybean protein concentrate (SPC) was studied in two milk replacer experiments, in which the SPC supplied 50% of the total nitrogen. In experiment 1, six lambs were used in a double 3 × 3 latin square digestion and nitrogen balance trial. The three treatments of the SPC in the milk replacer were: control (no alkali), alkali 1 (0.05 N NaOH at 40 C, neutralized with HCl after 15 min), and alkali 2 (same as 1, but neutralized after 18 hr at 5 C). The remainder of the diet ingredients were homogenized with a Polytron. Alkali treatment increased digestibility of dry matter (91, 93, and 95%, P < 0.01, on the three treatments, respectively), nitrogen, and energy, but tended to reduce the percent of absorbed nitrogen that was retained (63, 61, and 60%, P < 0.20). The control (complete diet prepared with the Polytron) and alkali 1 treatments were compared in a growth and metabolism trial in experiment 2. Growth of a total of 19 lambs from about 4 days to weaning from milk replacer at 26 days of age tended to be lower on the alkali-treated than the control SPC milk replacer (179 vs. 215 g/day, P < 0.20); however, growth to 10 weeks of age was similar for both groups and averaged 250 g/day.

Three fish protein sources and milk by-products were used in milk replacers. Thirty Holstein heifer calves were fed five different milk replacers as follows: all-milk nitrogen control, and four with 65% of the nitrogen supplied by steam-dried herring meal and the remaining nitrogen from milk as: (a) skim milk powder, (b) skim milk and acid whey powders; and (c) acid whey powder partially neutralized with NaOH or (d) Ca(OH)2. Body weight gains were greater for calves fed the control milk replacer; from birth to 26 wk of age, calves weaned from this milk replacer gained 822 g/day, compared with 662, 731, 741 and 699 g/day, respectively, on diets a to d noted above (P < 0.05). A digestion and nitrogen balance trial with four bull calves fed the four herring meal milk replacers in a 4 × 4 latin square showed relatively poor utilization of the herring meal, especially for calves at 2–4 wk of age. The apparent dry matter digestibility was 75% when the acid whey in the diet was neutralized with Ca(OH)2, compared with 81% when it was neutralized with NaOH. Three milk replacers containing 62% of the total nitrogen from herring meal, isopropanol-extracted fish protein concentrate (FPC), or predigested FPC were compared using six Holstein bull calves in two 3 × 3 latin squares. Apparent digestion of dry matter and energy by the calves was similar for the three diets. Nitrogen digestibility was 82% in the herring meal and 86% in the predigested FPC diet (P < 0.05). At the end of the digestion trial, the calves were continued on the same diet to 91 kg body weight. Body weight gains by all calves averaged 1 kg/day. Loin roasts from the calves fed the herring meal diet were tougher and had an objectionable odor compared with those from calves fed the two FPC diets or whole milk. It was concluded that FPC could be a useful ingredient in calf milk replacers, and that herring meal was not well utilized by calves at 2–4 wk of age.

Milk replacers containing zero (all-milk) or 70% of the total protein from a soybean protein concentrate (soy-milk), with or without methionine supplementation, were fed to Holstein calves. Bull calves digested 91 and 89% of the dry matter (P < 0.05), and 87 and 82% of the nitrogen (P < 0.01) supplied by the all-milk and soy-milk replacers, respectively. Nitrogen retention averaged 41% of that consumed, with no difference due to protein source. DL-methionine (0.1% of the dry replacer) did not increase calf growth or nitrogen retention. Heifer calves fed whole milk, the all-milk replacer or soy-milk replacer plus methionine, and hay and concentrates, gained 496, 550 and 526 g/day, respectively, to weaning at 7 weeks of age (treatment means not significantly different at P < 0.05). Weight gains for these three groups of heifers from 7 to 15 weeks of age were 723, 650 and 599 g/day (significant difference between whole milk and soy-milk at P < 0.05), respectively. It was concluded that the soybean protein concentrate could supply a major portion of the protein in milk replacers for rearing dairy calves.

The objective of this research was to determine the effect of different starters consisted of dried whey and soy proteins with low anti-nutritive factors (ANFs) + amino acids (lysine and methionine) on body measurements, biochemical parameters, and feed consumption of early-weaned female Holstein calves. Based on the starter, calves were divided into four groups: i) control (control starter), ii) E1 (starter with added dry whey), iii) E2 (starter with added soy proteins with low ANFs + lysine and methionine), and iv) E3 (starter with added dry whey and soy proteins with low ANFs + lysine and methionine). Results indicate that different starters based on whey powder and soy proteins with low ANFs + lysine and methionine significantly affected the consumption of milk replacer and starter, the total consumption of dry matter, then withers in height, and body length (among body traits) as well as NEFA (among blood biochemical parameters) of female Holstein calves. Finally, starters based on dried whey and soy proteins with low ANFs + lysine and methionine could be recommended to optimize the growth and feed consumption.

Daily Gain

Dehulled, low-erucic acid–low-glucosinolate, full-fat rapeseed (FFRS), was studied as a protein source in milk replacers for lambs. Before being incorporated into the milk replacers to provide 25% (FFRS-25) or 50% (FFRS-50) of the total dietary protein, the FFRS was either passed through a colloid mill (milled) or left unmilled. When compared with an all-milk protein diet (FFRS-0), inclusion of the unmilled FFRS decreased the digestibilities of dry matter, nitrogen and energy (P < 0.01). Addition of unmilled FFRS to the milk replacer also decreased N retention (P < 0.01), but did not affect average daily gain. Addition of the milled FFRS to the milk replacers resulted in higher digestibilities of dry matter, nitrogen and energy and better retention of nitrogen than when the unmilled FFRS was added. However, the colloid-milled FFRS diet still was not as highly digestible as the all-milk diet. Increasing the level of substitution with milled FFRS from 25 to 50% produced a further decrease of about 4 units in the digestion coefficients and of 9 units in the retention of nitrogen expressed as a percent of the intake. Serum cholesterol levels just prior to and 2 h after feeding were not affected by the dietary treatments. Histology of liver biopsy samples taken at 22 days of age and of hearts and livers at market weight showed no detrimental effect on these organs from feeding low-erucic acid, low-glucosinolate FFRS to lambs. Based on growth trials it is concluded that low-erucic acid, low-glucosinolate FFRS, after colloid milling, can replace from 25 to 50% of the milk protein and most of the fat in lamb milk replacers without significantly affecting animal performance.
