Soya Bean Meal

Fishmeal is a suitable protein source for pregnant and lactating ewes, providing higher levels of undegradable protein than vegetable protein sources, with an improved biological value (Robinson, 1987). Vegetable protein sources may however be improved by formaldehyde treatment to reduce protein degradability and by the addition of rumen-protected amino acids. The objective of the current experiment was to compare the effects of feeding concentrates containing fishmeal with concentrates containing soya-bean meal, formaldehyde treated soya-bean meal and formaldehyde treated soya-bean meal with rumen-protected methionine.

Fishmeal is a suitable protein source for pregnant and lactating ewes, providing higher levels of undegradable protein (UDP) than vegetable protein sources, with an improved biological value (Robinson, 1987). The lower amounts of UDP supplied by vegetable protein sources may however be improved by formaldehyde treatment. The objective of the current experiment was to compare the effects of feeding concentrates containing fishmeal with concentrates containing vegetable protein sources with or without formaldehyde treatment.

1. Nitrogen balance studies were conducted on 8 early-weaned calves fed on four diets containing respectively Peruvian fish meal, soya bean meal, groundnut meal and dried distillers grains as the major sources of protein.2. Nitrogen retention differed significantly between diets, being highest on the fish meal diet, and lowest on the groundnut diet.

Soya Bean Meal

Vegetable proteins, including soya-bean meal (SBM), can only be included in diets for newly-weaned piglets in restricted amounts as they can induce a transient local gut hypersensitivity. This hypersensitivity may be a causative factor in post-weaning diarrhoea. Previous studies have indicated a strong maternal influence on the response of piglets to SBM. The object of the current experiment was to assess more formally maternal influences on weaning performance of piglets

SUMMARYSoya-bean meal and rapeseed meal treated with 0, 0·4 or 0·8 g formaldehyde/100 g crude protein (N × 6·25) was incubated in the rumen in nylon bags with 10 and 40 μm aperture.Disappearance of dry matter and nitrogenous compounds was reduced with increasing formaldehyde treatment.The proportion of acid-pepsin soluble nitrogen in the undegraded residues of untreated and treated soya-bean meal was similar to the original samples. For rapeseed meal the proportion of acid-pepsin soluble nitrogen in the undegraded residues decreased with increasing rumen incubation time. This reduction decreased with increasing formaldehyde treatment.Concentration of amino acids in the undegraded residues did not generally deviate from those in the original samples. However, a distinguishable decrease in the methionine concentration was observed in all the rapeseed meal samples and in glutamic acid concentration in rapeseed meal treated with 0 and 0·4 g formaldehyde/100g- crude protein.Most of the changes due to rumen incubation were smaller using the 10 μm bags than using the 40 μm bags. However, the bag pore size did not play a decisive role in the conclusions of the results given.

AbstractTwo trials, one with 36 twin-suckling Chios ewes and the other with 32 twin-suckling Damascus goats, were conducted to study the effect of protein source (fish meal v. soya-bean meal) on the pre-weaning milk yield of the dams, and the growth performance of their offspring. The control (C) concentrate mixture was similar in both trials, using soya-bean meal (SBM) (195 kg/t) as a source of supplemental protein. In the experimental diet (FME) of the ewe trial, SBM was replaced completely by fish meal (FM) whereas in the goat trial (FMG) 83 kg of SBM were replaced by 50 kg FM. Dry matter (DM) and crude protein (CP) degradation of the three isonitrogenous mixtures were measured using nylon bags incubated in the rumens (2, 6, 16, 24 and 32 h) of three Damascus goats. There were no significant differences between mixtures for DM and CP effective degradability at 005 per h outflow rate. At 0·08 per h outflow rate however, lower degradability values were obtained with the FME than with the C diet. There were differences in the effective CP degradability of SBM and FM used in the ewe trial, but the FM used in the goat trial was of higher CP degradability and similar to that of SBM. Ewes on FM produced more milk than those on the control diet (C 3·44 v. FME 3·84 kg/day), whereas milk yield of goats was similar in the two treatments (C 3·87 v. FMG 3·82 kg/day). There were no differences between treatments for ewe milk fat (C 44 v. FME 43 g/kg) or protein concentration (C 54 v. FME 53 g/kg). Goats on fish meal (FMG) produced milk of higher protein (C 37 v. FMG 40 g/kg), but of similar fat (C 42 v. FMG 43 g/kg) concentration to those on the SBM (C) diet. With the exception of the better conversion (milk: gain ratio) efficiency (C 5·17 v. FME 4·44) of male lambs sucking ewes on the FM diet, no other differences were observed in the performance of lambs or kids. Lambs consumed less milk than kids (lambs: males 4·69, females 5·13; kids: males 6·63, females 6·98) per unit of weight gain.

SUMMARYField beans were compared with fish meal and soya bean meal as a protein source for young calves, and the effect of processing beans and barley on the digestibility of the diet was measured with older, castrated male cattle.In calves given equal nitrogen intakes, apparent nitrogen digestibility was lower with field beans than with soya bean meal or white-fish meal, but nitrogen retention (g/day and percentage of intake) in calves given beans was between that obtained with fish meal and soya bean meal. The dry-matter digestibility of diets containing 20 % whole or rolled beans together with rolled barley was 80 % but fell to 74 % if the barley was given whole.

Ground Material

The degree of processing of protein-rich feeds affects their physical properties. Seeds which are less comminuted, whether cracked or rolled, may have properties which make their behaviour, in the rumen and postruminally, distinct from fine ground material and which may therefore alter their performance as feed proteins. The use of lupin seeds as a replacement for soya in ruminant diets has been demonstrated (Moss et al, 1997). This project aimed to assess whether the processing of lupin seeds, either hammer milling or rolling, affected the performance of young cattle fed the seed as their principal source of protein.

Since, under Irish conditions, the source of protein used in pig rations often varies from one area to another, an experiment was conducted to determine the accumulation of copper in the tissues of pigs given the commonly-usedprotein sources in diets containing 250 ppm of supplemental copper. The protein sources compared were (a) white-fish meal (370 ppm Cu), (b) soya bean meal (17 ppm. Cu), (c) roller-dried skim milk (2 ppm Cu), and (d) a mixture of soya bean meal and meat and bone meal (5 ppm Cu) (Table 1). The minerals, vitamins and copper sulphate were premixed with about 5 kg. of barley and distributed over the total feed before mixing. The copper sulphate was sieved to remove coarse particles. Analyses of complete feed mixtures are shown in Table 1. As far as possible, the rations were balanced for crude protein, calcium and phosphorus.
