Milk Replacers

Sixteen calves 3–28 days of age were fed milk replacers containing 15% added fat with 0, 5, 10 or 15% rapeseed oil (27% erucic acid) substituting for lard. The protein in these replacers was entirely of milk origin. The rapeseed oil was 69% digestible, compared to 94% for the lard, and its use resulted in depression of the digestibility of protein from 80 to 66% as the portion of rapeseed oil rose from 0 to 15%. Three calves were fed a milk replacer containing 10% lard and 10% rapeseed oil, in which 60% of the protein of milk origin was replaced by protein from fish protein concentrate and from brewers’ yeast. The calves showed progressive improvement in their ability to digest amino acids in successive 2-day periods. Average amino acid digestibility increased from 72% at 4–6 days of age to 87% at 16–18 days of age, at which time utilization about equalled that expected on milk-origin diets.

Biological Value

Milk chocolate is particularly popular with different age groups. It is characterized by low protein content with a large amount of fats and carbohydrates determining the food imbalance of the product. In conditions of high-grade animal proteins deficiency the selection of high-quality protein-containing ingredients for food production is very relevant. The aim of this work is to study the protein adequacy of various components of milk chocolate to enhance its biological value. The amino acid scale method has been used to assess the biological value of proteins; it is based on the determination of amino acid (chemical) score. It has been found that the limiting biological value amino acid for classical white raw ingredients of milk chocolate (cocoa products and milk powder) is methionine + cysteine. For constructing chocolate formulas with increased biological value it is advisable to use protein-containing raw materials (whey protein concentrate, oat flour, etc.) to compensate for the limiting amino acids. The indicator of amino acids utilitarianity of proteins of raw milk chocolate components has been calculated. On the basis of the utilitarian index we have established the coefficient of utilitarian of the amino acid composition of the raw materials characterizing essential amino acids' balance. We have determined the biological value of protein and the amino acid composition imbalance coefficient. It has been found that the amino acid composition of milk and whey protein concentrates is most balanced compared to the amino acid composition of traditional protein-containing raw components of milk chocolate. The limiting acid of whey protein concentrate is valine, which makes its use in the manufacture of chocolate products more attractive compared to milk protein concentrate (the limiting amino acid is methionine + cysteine). In the group of vegetable non-conventional raw materials oat and buckwheat flour are characterized by the best indicators of biological value. The amino acid adequacy of oat flour is comparable to the qualitative protein indicators of cocoa products, the limiting amino acid is lysine. Buckwheat flour is characterized by the smallest imbalance in amino acid composition, which distinguishes the proteins of this raw material with the highest degree of digestibility compared with the proteins of all the studied protein-containing components of milk chocolate.

Two experiments were carried out with Holstein heifer calves to determine the effect of supplying a major portion of the protein in milk replacers by isopropanol-extracted protein concentrate from whole herring (FPC) or a mixture of FPC and soybean protein concentrate (SPC). Milk replacers were compared with whole milk in experiment 1. All calves were abruptly weaned when consuming 0.5 kg starter/day, or by 5 weeks of age. Calf performance was similar when the pre-weaning liquid diet was whole milk, or milk replacers containing either milk protein or 50% of the protein from FPC. Average daily gains to weaning and to 26 weeks of age for all calves were 377 and 692 g/day, respectively. Calves in experiment 2 were fed either an all-milk protein milk replacer or one containing 98% of the protein equally from FPC and SPC. Both milk replacers were fed once daily either six or seven times per week. Calf growth to weaning was lower on the FPC–SPC formula (283 vs. 364 g/day, P < 0.01), but was not significantly different (P < 0.05) to 15 weeks of age (618 vs. 643 g/day). Feeding milk replacer six vs. seven times per week had no significant effect on calf growth. Digestibility coefficients of dry matter, nitrogen, and energy were similar in bull calves fed the all-milk or FPC–SPC protein milk replacers, but retention of absorbed nitrogen was less on the latter diet (54 vs. 45%, P < 0.10).

Ayrshire bull calves were weaned from whole milk or milk-replacer at 7 weeks of age, and at two different body weights, namely 55 and 46 kg. A maximum of 1.82 kg starter was fed daily to 15 weeks of age and 1.82 kg grower concentrate to 180 days of age.Calf performance did not differ significantly by weaning at 7 weeks or 55 kg. Weight gains to weaning and to 15 weeks were significantly lower for calves weaned at 46 kg. The average 180-day body weights for calves weaned at 7 weeks, 55, and 46 kg were 150, 146, and 140 kg, respectively.Whole milk or milk-replacer feeding produced identical calf growth to 180 days of age. Milk-replacer tended to increase preweaning and decrease post-weaning growth of calves weaned at 46 kg compared with whole milk. The augmented preweaning starter intake by calves fed replacer is discussed in relation to the digestible energy content of milk-replacers. It is suggested that energy supplied by plant carbohydrates should not be included in replacers for early-weaned calves, due to the low digestibility of starch by calves until 3 or 4 weeks of age.

By product that rich in protein such as fish roes are potential as raw material for protein concentrate. This research aimed to utilize skipjack roes to produce protein concentrate and to characterize its functional properties. The method used to extract protein was defatting method using isopropyl alcohol and ethanol with extraction times of 1, 2, and 3 hours.  The results showed that skipjack roes contained 19.81% of protein, 3.41% of fat, 71.32% of moisture, 2.04% of ash, and 1.53% of carbohydrate (by difference). Defatting method using isopropyl alcohol for 3 hours produced the best roe protein concentrate (RPC).  The product meets to the quality requirements of fish protein concentrate type B, contained protein and fat of 71.79% and 2.78%, respectively. This product also had functional properties as follows: water absorption capacity (1.57 ml/g), oil absorption capacity (1.82 g/g), emulsion capacity (81.65%), bulk density (0.51 g/ml), foaming capacity (1.90 ml), foaming stability (0.22 ml) and protein digestibility (95.86%).  Lysine and leucine became the major essential amino acid of RPC, with values were 70.76 and 64.91 mg/g protein, respectively. The composition of amino acids of RPC skipjack consisted of 8 essentials amino acids, 5 non-essentials amino acids and 2 semi-essentials amino acids.

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

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.
