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.

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.

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.

Formalin (37% formaldehyde) was added at 0–0.15% (v/w) to 20% (w/w) solids milk replacers to determine its effect on utilization of nutrients, growth, feed intake and incidence of abomasal bloat in lambs. Formalin at 0.05 or 0.10% in the diet had no effect on growth, nitrogen retention and apparent digestion of dry matter, nitrogen and energy by lambs. The incidence of abomasal bloat was markedly reduced in lambs fed milk replacer twice daily to appetite when 0.10%, compared with 0 or 0.05% formalin was added. Milk replacer intake by lambs and body weight gains were reduced by the inclusion of 0.15% formalin, but there was no adverse effect on the digestive tract mucosa. Lambs fed milk replacer ad libitum at 17 C with 0.05% formalin added tended to gain more body weight to weaning than those fed refrigerated milk replacer without formalin (237 vs. 192 g/day); weight gains to 10 wk were 224 and 222 g/day, respectively. The same milk replacer containing 0.05% formalin was fed to lambs either ad libitum or restricted to 900 g/day after 8 days of age. Weight gains to weaning at 28 days were 311 and 212 g/day, and to 10 wk were 259 and 220 g/day, respectively. Milk replacer dry matter intakes per lamb were 8.8 and 5.4 kg. There was no abomasal bloating in lambs when fed ad libitum or restricted amounts of milk replacer with 0.05% formalin added.

Milk Replacers

Two milk replacers, formulated to provide one-half the dietary protein from either pea protein concentrate (PPC) or pea protein isolate (PPI), were compared with a milk replacer based on reconstituted skim milk (SM). The milk replacers were fed to pre-ruminant Holstein-Friesian calves aged 3–23 days and dry matter and protein digestibilities were determined. The mean protein digestibilities of the SM (control) and PPI milk replacer were 84.0 and 75.4%, respectively (the difference was not statistically significant), and were greatly superior to that of the PPC milk replacer (47.5%). The PPC contained, on dry matter basis, 61.2% protein, 5.5% starch and 9.8% total sugars. The sugars detected were sucrose (3.7%), raffinose (1.5%), stachyose (3.3%) and verbascose (2.5%). The PPI contained 92.8% protein and less than 1.0% starch or total sugars; the only sugar detected was sucrose (0.7%). Lactose was the only sugar present in SM. Although other factors cannot be ruled out, it was concluded that starch and oligosaccharides were mainly responsible for the poor digestibility of the pea proteins in the PPC milk replacer.

ABSTRACTResults are presented from six trials dealing with aspects of management on the cold ad libitum system of calf rearing using an acidified milk replacer containing over 600 g skim milk powder per kg.Thirty-six calves were housed in pens of six for each trial and were fed through a teat and pipeline from a storage barrel. Acidified milk replacer, pH 5·6, was mixed cold at 125 g/1 and made available ad libitum to 3 weeks. A rationed allowance was given daily, on a reducing scale, over the following 2 weeks with weaning completed at 35 days. A pelleted dry food containing 180 g crude protein per kg, together with water in buckets and barley straw in racks, was available ad libitum throughout. Each trial lasted 8 weeks. Results for the mean of the six cold ad libitum trials involving 216 calves were compared with the mean results of 10 conventional bucket-fed trials carried out separately at the same unit, involving 912 calves. All calves were purchased British Friesian male (bull) calves.Calves on the ad libitum system showed improved live-weight gains of 9·4 kg at 3 weeks, 8·8 kg at 5 weeks and 7·5 kg at 8 weeks, compared with the conventional system. The consumption of milk replacer powder was higher in ad libitum trials at 29·4 kg cf. 12·5 kg by bucket but intake of pelleted dry feed was lower on the ad libitum system at 50·7 kg cf. 71·3 kg to 8 weeks. Calf appearance scores were significantly improved on the ad libitum system which gave the main improvement in performance in the first 3 weeks.

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.

Full-fat soybean flour (FFSF) was prepared from dehulled soybeans by extraction with water and NaHCO3, colloid milling, cooking and spray-drying. The apparent destruction of soybean trypsin inhibitor (SBTI) prior to cooking was variable. A rat bioassay for SBTI was conducted with diets containing 1.6% nitrogen from cooked and uncooked FFSF. Cooking the FFSF for 1 h markedly improved rat growth (4.0 vs. 2.6 g/day, P < 0.01) and weight gain/protein intake (3.3 vs. 2.5, P < 0.01). The cooked FFSF was also used in three lamb experiments to supply 0, 30, 50 or 60% of the nitrogen in milk replacers. Apparent digestion coefficients for energy were 88, 92 and 92% (P < 0.05), and for nitrogen were 94, 95 and 92% for lambs fed milk replacers containing 0, 30 or 60% of the nitrogen from FFSF. The percent of total nitrogen intake retained was 61, 63 and 55, respectively. The lower energy digestion by lambs on the zero FFSF diet was attributed to the fat being supplied only by tallow. In another experiment, when unrefined soybean oil, equal to that supplied by FFSF, was used in place of the tallow in an all-milk protein milk replacer, energy digestion by lambs was greater than with a milk replacer containing FFSF. Milk replacers containing a mixture of spray-dried skim milk and whey powders resulted in higher nitrogen digestion and retention by lambs than did a mixture of roller-dried buttermilk and whey powders, when 50% of the nitrogen was supplied by FFSF. It was concluded that milk replacers containing up to 60% of the total dietary nitrogen from FFSF were utilized satisfactorily by milk-fed lambs.

Two growth trials were conducted to determine an optimum level of fat in milk replacer and an optimum level of protein in creep feed for artificially reared lambs. In experiment 1, milk replacers containing 31 or 36% fat (dry matter, DM, basis) were fed ad libitum to 58 lambs at 1 day of age. The protein was supplied by low-heat spray-dried skim milk powder and Na caseinate and the fat from a mixture of 10% coconut oil and 90% tallow. A finely ground unpelleted creep feed with 20% protein, on a DM basis, was fed ad libitum. The lambs consumed more of the 31% fat milk replacer and gained more live weight (288 vs. 254 g/day; P < 0.025) to weaning at 25–30 days of age than did lambs fed the 36% fat formula. Weight gains to 10 wk of age were 190 and 170 g/day, respectively (P < 0.10). In experiment 2, 84 lambs were fed a 26% fat milk replacer ad libitum, and creep feeds with 15, 20 or 25% protein (DM basis). The supplementary protein was supplied by herring meal and soybean meal. Weight gains of lambs to weaning at 24 days of age were similar on the three creep feeds. However, gains to 10 wk of age averaged 218, 235 and 244 g/day (P < 0.05) on the 15, 20 and 25% protein diets, respectively. One and 2 kg of DM were consumed/kg lamb body weight gain to weaning and to 10 wk of age, respectively. It was concluded that the milk replacer should contain 26–31% fat, and the creep feed 20% protein or more for maximal performance of artificially reared lambs.

ABSTRACTTwo feeding trials were carried out with Israeli Friesian male calves, commencing at an average age of 7 to 10 days, and covering a suckling period of 30 days followed by a further 90 days. A conventional starter, or one that contained cotton hulls, was used. In each experiment one group of 10 animals served as a control and a similar group was monensin-supplemented. No coccidia were found in the animals. In experiments 1 and 2 monensin supplementation was associated with increased daily gains of 10% and 47% during the suckling period and of 6% and 17% during the next 90 days, but only the differences obtained in experiment 2 were significant. In both experiments, dry-matter intake relative to body weight was higher with monensin supplementation in period 1, but reduced in period 2. The effect of monensin on molar proportions of acetic and propionic acids was smaller than that reported by previous authors for older cattle.A separate digestibility trial showed that monensin administered to suckling calves, either with milk replacer or directly into the rumen, improved dry-matter digestibility, increased the excretion of amylase, and tended to reduce that of trypsin and chymotrypsin.

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.
