The Relationship

Experiments were conducted to estimate the variability in growth promoting ability of seven meat meals (MM) or meat and bone meals (MBM) for pigs and the relationship between pig growth and chemical or chick tests. The meals were fed as the sole protein supplement in wheat-based diets to Large White pigs over the 18-73 kg growth phase. The diets were fed at the restricted rate of 7.2 g crude protein and approximately 114 kcal digestible energy per kg liveweight per day. The nitrogen retention of pigs and dry and organic matter digestibilities of the diets were determined. With the nutritional regime adopted, there was little difference (12 per cent) in the growth promoting ability of the seven diets for pigs, with one brand inferior to the other six. This difference appeared to be due to lower protein quality. The seven meals varied considerably in chemical composition (bone content 22-55 per cent, crude protein 45-59 per cent). There appeared little relationship between chemical composition of the diets and their growth promoting ability. Dietary calcium levels varied from 1.6-3.0 per cent but there was no apparent effect of calcium level on pig growth. 'Available' lysine levels in the meal varied from 3.1-3.7 per cent with the inferior meal having the lowest available lysine content. All diets contained considerable quantities of minerals as a result of the inclusion of MM or MBM and the diets contained the estimated requirements of pigs for major minerals. There was little relationship between chick growth on the seven diets and pig growth (r = 0.11). Chick growth was correlated with dietary calcium (r = -0.72) and feed intake (r = 0.64). When the diets were equalized for calcium, the relationship between chick growth and pig growth increased (r = 0.62). The results indicated that the calcium content of a meal was a major factor affecting its growth promoting ability for chicks but not for pigs. As the depressed chick growth was associated with lowered feed intake under ad lib. feeding, it was possible that the restricted feeding of the diets to the pigs minimized the development of depressing effects of calcium.

On the basis of chick growth and efficiency of feed conversion, wide variation in the nutritional value of Australian meat meals has been observed, with all samples inferior in value to imported fish meal. No necessary relationship was observed between the crude protein and fat contents of the meals and the chick growth-promoting ability or efficiency of feed conversion. Small variations in growth response were significantly associated with the amount of ash contributed by meat meals to diets. However, ash was not the major cause of the differences between high and low quality meals. The addition of ash or ether extract from low quality meat meal to high quality meal did not indicate the presence of growth-depressing or toxic factors in these fractions. The results are interpreted as indicating that neither total protein content, ash content, or lipid content, nor ash or lipid toxic factors was the main cause of variation in the nutritional value of the meat meals studied.

Experiments were conducted to determine the effect of rate of feeding on the differences in growth promoting ability of wheat-based diets containing meat meal or meat and bone meal as the sole protein supplement for pigs. The value of laboratory rats in assessing diet quality for pigs was also investigated. There was no difference in the growth promoting abilities of diets containing MM or MBM under restricted feeding but under ad lib. feeding variation between the diets occurred. Rat responses to the dietary treatments were inconsistent with the pig responses. The results confirmed previous findings that under restricted feeding meat meals and meat and bone meals had similar growth promoting abilities for pigs.

The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara.

Maize-meat meal and maize-meat and bone meal diets were supplemented with dl-tryptophan, l-lysine or a mineral-vitamin-antibiotic (MVA) premix and fed to pigs during the 1s to 45 kg growth phase. Diets were offered at an estimated 145 kcal of digestible energy and 7g crude protein per kg liveweight per day. The basal maize-meat meal diet produced poor growth and feed conversion and the combined addition of all three supplements increased growth by 46 per cent, feed conversion by 21 per cent, and lean in the ham by 4.7 per cent. This effect resulted from responses to dl-tryptophan, the MVA and an interaction between dl-tryptophan and l-lysine, with l-lysine depressing gain and feed conversion in the absence of dl- tryptophan and increasing gain, feed conversion, and lean in the ham in its presence. The basal maize-meat and bone meal diet also produced poor growth and feed conversion, and the combined addition of all three supplements resulted in an 82 per cent increase in growth, a 35 per cent increase in feed conversion, and a 3.3 per cent increase in lean in the ham. Both dl-tryptophan and MYA separately increased growth and feed conversion and combined they had an even greater effect. The l-lysine increased feed conversion and lean in the ham. The l-lysine also increased growth rates on the dl-tryptophan supplemented diets, but this effect was not significant (P>0.05).

The comparative value of meat meal as a protein supplement to barley, oats, sorghum, and wheat-based diets was investigated for pigs during the 18-45 kg growth phase. Diets were offered at the rate of 129 kcal digestible energy and 7 g crude protein per kg liveweight per day. Two methods of estimating digestible energy in the diets were also examined. The major differences recorded (Pt0.05) were : Growth rates-Wheat barley and sorghum, oats and barley sorghum. Feed conversion ratios-Wheat barley: oats and sorghum. Protein efficiency ratios-Wheat and oats barley sorghum. Lean in ham-Oats and barley sorghum and wheat. When the magnitude of all differences was considered the results indicated that the protein quality of the sorghum-meat meal diet was lower than that of the other three diets. The correlation between digestible energy values estimated by two methods (energy in feed X dry matter digestibility) and (energy in feed-energy in faeces/feed intake) was significant (r = 0.98)

Different Levels

On a single feed an animal can increase its intake of a nutrient (eg. protein), as its ratio to energy is reduced, only by increasing its rate of energy intake. When given, as a choice, two feeds of a different protein but equal energy contents, it can vary its protein intake independently of Its energy intake by varying the proportion of each feed in its diet.The experiment described here was designed to investigate the effect of feed protein content on the feed intake of young pigs and to test the proposition that young pigs, when given a choice between two feeds of different protein contents, a combination of which is non-limting, will select a diet which meets their protein requirements. In addition an investigation of the rules which govern the diet selection was carried out.Four feeds (L, A, B and H) with similar energy contents (16.5 MJ DE per kg fresh feed) but different levels of crude protein (CP) were formulated and made into pellets. All feeds were intended to be non-limiting in vitamins and minerals.

SUMMARYTwo experiments were conducted with 84 male British Friesian calves to estimate their nitrogen and sulphur requirements between 5 and 11 weeks of age. A basal 12 % crude protein (CP) diet was supplemented with meat meal, soya bean meal or urea to 15 or 18 % CP, and with sulphur to reduce the nitrogen to sulphur ratios of the diets to about 10 to 1.The weight gains and feed conversion ratios of the calves given the 12% CP diets were significantly poorer than those of the calves fed on the diets containing 15 or 18% CP, irrespective of the CP supplement used. The supplementation of the urea-containing diets with sulphur caused a significant increase in feed intake and weight gain.The digestibility of nitrogen and dry matter increased with increasing CP content of the diets and was greater for the diets supplemented with urea than for those supplemented with meat meal or soya bean meal. Sulphur additions also increased the nitrogen digestibility. The retention of nitrogen, when corrected for feed intake, was greater in the calves fed on the diets containing 18% CP than in those fed on the 15% and 12% CP diets.The supplementation of the diets with sulphur increased the digestibility of sulphur, its excretion in urine and its retention. The concentration of urea in the blood plasma increased with increasing dietary CP content, and was higher in calves given urea.

SUMMARYNineteen feedstuffs were evaluated for total digestible nutrients (TDN), digestible energy (DE) and metabolizable energy (ME) using growing pigs. DE values, on a drymatter basis, ranged from 1570 kcal/kg D.M. (grassmeal) to 4890 kcal/kg D.M. (BP Grangemouth protein). ME averaged 97·4% of DE for cereal feeds and 81·9% of DE for protein feeds, the ratio of DE to ME being significantly affected by the crudeprotein content of the feedstuff:ME/DE × 100 = 99·7–0·18 × crude protein (%): r = –0·94; P < 0·01.TDN was more closely related to ME than DE:DE (kcal/kg D.M.) = 45 TDN + 156: r = 0·92; P < 0·01,ME (kcal/kg D.M.) = 43 TDN + 71: r = 0·98; P < 0·01.ME values were corrected to both 30% and 0% nitrogen retention. Correction to 30% retention caused a maximum change of 3% in ME value while correction to 0% retention had a variable effect related to protein content of the feedstuff:(ME(N0)/ME) × 100 = 98·3–0·113 × crude protein (%): r = –0·80; P < 0·01.

ABSTRACT1. The digestible energy content of 14 meat meals and meat and bone meals produced from different regions in eastern Australia was determined using growing pigs. The relationship between digestible energy content and chemical constituents in the meals was investigated.2. Digestible energy ranged from 9·4 to 13·9MJ/kg (air-dry basis). This variation in digestible energy was best described by the regression equation:3. Simpler equations, with only gross energy or crude protein and ether extract were:4. Digestibility of the energy and crude protein in the meals ranged from 0·63 to 0·77 and 0·73 to 0·91 respectively. These variations were not related to any of the major chemical constituents of the meals.
