A series of trials was conducted to investigate the effects of Conmar 80 (80% CP), a new commercial hexane-extracted fish meal, as a protein source in creep and weaner-starter diets. Eight dietary treatments, comparable in composition except for the protein source, were offered in three experiments to 112 litters and 44 Yorkshire piglets. The first two trials were designed to compare piglet performance, during the suckling and early-weaning period when Conmar 80 was included as part of the creep diet or the starter diet protein. The third trial was designed to study the digestibility of increasing levels of Conmar 80 as a protein source in the weaner ration of 70-d old barrows. The results of this study indicate that piglet performance was not adversely affected when Conmar 80 was substituted at 3.5–5.0% of the creep diet or when Conmar 80 was used as the sole animal protein source in the starter diet. The digestibility of dry matter and crude protein was 85.6 ± 0.05% and 85.1 ± 0.24%; 74.7 ± 0.14% and 73.6 ± 0.53% when Conmar 80 was substituted in the weaner ration at the 5% and the 10% level respectively. The digestible energy was 13.5 ± 0.01 and 13.4 ± 0.04 MJ kg−1, respectively. It is concluded that Conmar 80 can satisfactorily be included to replace 14.5–22.0% of the dietary protein in pig creep and weaner feeds.

Dry Matter Digestibility

Pig performance was compared on wheat based diets supplemented by two levels of either meat and bone meal or fish meal plus skim milk powder. The dry matter digestibility and nitrogen retention on these diets were determined and the effect of adding zinc to diets containing meat and bone meal was examined. At the higher level, fish meal plus skim milk powder produced greater daily gains between 60-160 lb than the meat and bone meal, but feed conversion and carcase lean were not affected. At the lower level, fish meal plus skim milk powder produced leaner carcases and greater daily gains between 60-160 lb than the meat and bone meal supplement, but had no effect on feed conversion. Between 60-100 lb, feed conversion was affected by level but not by supplement, and the higher level of fish meal plus skim milk powder produced greater daily gains than all other diets. The higher levels of each supplement produced greater nitrogen retentions and leaner carcases than the lower levels. Dry matter digestibility was least on the higher level meat and bone meal. Zinc supplements had no effect on performance.

Ad Libitum

Thirty-two British Friesian calves were individually offered milk substitutes ad libitum twice daily for 12 weeks. The milks were reconstituted to contain 170, 200, 230 or 260 g dry matter (DM) per kg, using spray-dried skim milk powder and homogenized fat-filled powder containing 500 g fat per kg. Drinking water was available ad libitum at all times. The last two blocks of four calves were used to measure the digestibility, absorption and retention of the constituents of the diets at 2, 6 and 11 weeks of age.The DM intakes of the calves given the four diets were variable but generally increased with increasing DM concentration, mean values being 61·5, 59·5, 66·0 and 73·3 g DM per kg M0.75. As the calves increased in age, their intakes decreased from 67·3 g DM per kg M0.75 at 2 weeks of age to 61·1 g DM per kg M0.75 at 8 weeks of age.The higher DM concentrations and intakes were associated with the higher rates of weight gain; the mean live weights at 12 weeks of age being 121·8, 123·9, 135·3 and 141·6 kg for the calves offered milks reconstituted at 170, 200, 230 and 260 g DM per kg respectively.The concentration of the DM had no effect upon the coefficients of digestion or absorption nor on the retention of energy, protein, calcium or phosphorus. The digestibility of protein increased, whilst the absorption and retention of Ca and P declined with age.Intake of drinking water did not change with age, but was higher for calves given the milk containing 260 g DM per kg than for those given the other three concentrations. The total water intakes were similar for the calves given milks containing 200, 230 and 260 g DM per kg.The linear relationship of DM intake to DM concentration of the milk substitute suggested a lower level of intake in the present experiment, than was observed in a previous experiment (Ternouth, Stobo, Roy and Beattie, 1985b) when the milk concentrations were lower and drinking water was not available. When the concentrations of the DM were re-calculated to take into account the quantity of drinking water consumed, the relationships between DM intake and adjusted DM concentration for the two experiments were similar.

Three spray-dried powders were prepared after heating skim milk for 30 min at 60 C (LT), 73.9 C (MT) or 85 C (HT). Each was reconstituted to two concentrations of dietary fat and fed to five or six calves for 26 days after purchase at approximately 1 wk of age. Calves receiving the HT skim milk had significantly (P < 0.05) higher incidence of diarrhea and slower rate of gain over 19 days on test as compared with those fed the MT and LT skim milks. Subsequently growth rate was unaffected by the skim milk source and there were interactions of fat level with skim milk source. The high fat level (22.2% of dietary dry matter) resulted in a higher incidence of alopecia than in calves receiving the low fat level (16.2% of dietary dry matter). Nutrient digestibilities and nitrogen balance, measured from day 20 to day 26, were unaffected by skim milk treatments or fat concentrations. This experiment indicated that young calves, less than 3 wk of age, require a diet based on skim milk that has not been severely heat-treated and the curd formation is a suitable index of quality for such milk replacer diets. Where control diets for milk-replacer studies are designated "all milk protein," it is important for correct interpretation to define their curd-forming characteristics. For older calves, coagulation appears not to be a requirement.

The operation of the Willems Polytron® to prepare batches of high-fat (27–35%, air dry basis) milk replacers is described. Most milk replacers were mixed at 40% solids to minimize foaming, and were diluted prior to feeding. The Polytron homogenized fat in liquid mixtures at 55 or 65 C, and partially dispersed insoluble ingredients in soybean, rape-seed, and fish flours. The inclusion of 25% or more of partially delactosed acid whey powder increased the viscosity of the mixtures, and held insoluble ingredients in suspension for several hours. Homogenization of a milk replacer containing 73% skim milk powder and 27% bleachable fancy tallow (3% soybean lecithin added) markedly improved growth (425 vs. 190 g/day), dry matter, nitrogen, and energy digestion (92 vs. 73% for energy) and nitrogen retention (44 vs. 24%) by calves. Calf responses were similar when the liquid diet was homogenized at either 55 or 65 C. Homogenization with 3% soybean lecithin in the tallow increased digestion of dry matter, nitrogen, and energy by chives by 5–6% units (P < 0.2), and Ca by 16% units (P < 0.05) compared with no lecithin. Bleachable fancy or crude tallow and 3% soybean lecithin or 0.2% glyceryl monostearate in the fat gave similar calf responses.

We previously demonstrated that Lactobacillus casei K17, isolated from Korean kimchi, has high antioxidant levels in vitro and in vivo. However, its effect on Micropterus salmoides is unknown. In this study, we investigated the impact of L. casei K17 supplementation on the lipid metabolism, antioxidant response, liver histology, and fillet quality of M. salmoides. We randomly assigned 450 M. salmoides (33.0 ± 0.5 g) to six diet groups for 69 days. The diets were as follows: 0.85% normal saline; 10% skim milk powder; 1 × 108 CFU/g live L. casei K17 (LB); 1 × 108 live L. casei K17 protected by skim milk powder (MB); 1 × 108 dead L. casei K17 (DB); and L. casei K17 fermentation supernatant. MB significantly improved the crude protein, total collagen, alkaline-insoluble collagen, fiber numbers, hardness, chewiness, and gumminess of M. salmoides fillets (p < 0.05). LB significantly improved crude protein and fiber numbers (p < 0.05). Furthermore, dietary supplementation with LB, MB, and DB maintained normal liver histology, preserved liver function, and increased hepatic and hemal antioxidant status by enhancing antioxidant enzyme activities. Meanwhile, the three diets also promoted lipid metabolism by increasing HDL-C effectiveness and reducing total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels in serum and liver tissues, indicating that dietary supplementation with DB, LB, and MB had hypolipidemic effects on M. salmoides. MB and LB significantly improved fillet quality and LB, MB, and DB improved hemal and hepatic lipid metabolism and antioxidant response and reduced reactive oxygen species production, protecting M. salmoides hepatic cells from injury.

High-temperature-treated skim milk (HTSM) used in milk replacers for calves resulted in no growth response to an increased protein level as compared with low temperature treatment (LTSM), where an increase in protein level from 20.7 to 25.6% of the dry matter resulted in an increase (P < 0.05) in growth rate during the first 19 days on experiment. The HTSM resulted in a greater depression of gross energy intake than the LTSM when dietary fat levels were changed from high to low. Increasing the fat level from 18.0 to 20.9% of the dry matter improved calf health, and rate of gain (independently of energy intake) during early life. The intake of gross energy from high fat diets tended to be higher with the high protein level than with the low protein level. This tendency was reversed in the low fat diets. From 19 days of age to market weight (95 kg liveweight), energy intake increased with increased protein and fat in the diet. During this period, daily gain (after removing the effect of energy intake) responded only to increased protein level in the diet. However, calves fed HTSM had lower (P < 0.05) dressing percent than those fed LTSM.

SUMMARY1. Fifty-one Jersey, Ayrshire and British Friesian male calves were reared from birth to veal weights on one of three liquid diets.2. Two ultra-high fat milk powders containing 680 g fat, either beef tallow (T) or a mixture of coconut oil and beef tallow (CT)/kg dry matter were prepared and mixed with liquid skim milk (35 g powder/kg) to give diets TLS and CTLS, containing 200 g fat/kg dry matter. A third diet consisted of reconstituted spray-dried skim milk powder containing 200 g margarine fat/kg (MDS).3. The incidence of diarrhoea and of nasal discharge for all breeds, and of a high rectal temperature for the Ayrshire breed was greatest for calves given diet MDS and lowest for those given diet TLS. The incidence of lung lesions at slaughter was 100, 72 and 57% for the Jersey, Friesian and Ayrshire breeds respectively. Severity of lung lesions was lowest for calves given diet TLS.4. Dry-matter intake and live-weight gain, especially for the Ayrshire breed, were greater for calves given diets containing liquid skim milk and the ultra-high fat powders (TLS and CTLS).5. Fat digestibility was lowest on diet TLS. Protein digestibility increased with age. Digestibility of dry matter and lactose, and absorption of ash and calcium decreased with age. Calcium and N retention were lowest on diet MDS.6. Killing-out percentage was highest for the Friesian and lowest for the Jersey breed. Perirenal fat deposition was highest for the Jersey and lowest for the Ayrshire breed. Skin weight/kg0·73 was higher for the Ayrshire calves than for the other two breeds.

Rate Of Decline

The hypocholesterolemic property of skim milk powder (SMP) was investigated using rats in a series of six separate experiments. SMP was incorporated at a level of 25% by weight into stock diets or semipurified diets with casein or soy as the protein source. Ingestion of SMP with casein-based diets for periods of 5 to 12 weeks produced a transient hypocholesterolemia only when diets were introduced within 1 week of weaning. In two different experiments, when weanling rats were fed stock diets with or without SMP for periods of 8 and 16 weeks, SMP ingestion led to a transient decrease in plasma cholesterol (CH) levels in only one experiment. Finally, SMP was not hypocholesterolemic when fed to weanling rats with a soy-based diet for 8 weeks. Together, these results reveal that consumption of SMP does not consistently elicit hypocholesterolemia in rats. We found that to observe significant differences in plasma CH levels between the control and SMP groups, semipurified diets containing SMP had to be fed to rats within the first week of weaning; in addition, the diets had to be free of, or reduced in other components with cholesterol-lowering properties. Finally, the SMP-induced hypocholesterolemia that we observed appeared to facilitate the normal rate of decline in plasma CH levels during the post-weaning period, producing only a transient difference between control and SMP groups.

ABSTRACTThirty-six pigs were weaned at 21 days of age and were given diets supplemented with either dicalcium phosphate (DCP) or defluorinated rock phosphate (DFP) from 4 weeks of age until slaughter at 50 kg live weight. From 4 to 9 weeks of age the diets contained either skim milk powder (SKIM) or soya bean meal (SOY) as the main protein supplement. The dietary treatments were arranged in a 2 × 2 factorial design. From 9 weeks of age until slaughter, SOY was the only protein supplement used. Four 7-day measurements of phosphorus, calcium and nitrogen balance were made on each pig. Faecal endogenous P was estimated in two pigs per treatment by the 32P dilution method.There were no significant effects of P supplement on performance or on apparent absorption, true absorption or retention of P. The apparent absorption and retention of Ca were both 0·07 lower with DFP than with DCP in the period from 9 weeks of age to slaughter (P< 0·001).From 4 to 9 weeks of age there was no effect of protein supplement on performance. From 9 weeks of age to slaughter, when all pigs were given SOY, those which had received SKIM in the previous period grew slightly faster (P<0·05); their growth-rate overall, from 4 weeks of age to slaughter, was also significantly better (P <0·05).Pigs given SKIM showed a higher apparent absorption of P (P < 0·001) and higher apparent absorption (P<0·01) and retention (P<0·001) of both Ca and N from 4 to 9 weeks of age. Again, there were carry-over effects in the period from 9 weeks of age to slaughter, although the trends observed in the first period were reversed; pigs previously given SKIM showed significantly lower apparent absorption and retention of both P and Ca, and apparent absorption of N, than those previously given SOY.There were no significant effects of dietary treatments on the ash, Ca or P content of the fourth metacarpal.
