FEEDING FERMENTED SOYBEAN MEAL IN PIGLETS- REVOLUTIONARY CONCEPT: A REVIEW Полный текст
2022
G. Srinivasan
Fermentation of soybean meal eliminates the anti-nutritional factors of soybean meal making fermented soybean meal a potential lower-cost substitute for animal protein in piglet diets.Fermentation process using bacteria, fungal and yeast strains in soybean meal (SBM) is the novel technique which is used to remove the anti-nutritional factors of SBM. In general, two types of fermentation process namely Solid State Fermentation (SSF) and Liquid or Sub merged State Fermentation (SmF). Numerous studies were carried out to document the beneficial effects of feeding fermented soybean meal. Weaning is a stressful condition to the piglets which accompanied by diarrhoea, some time may lead to death. Antibiotic growth promoters can be added to the piglet diets but it is banned in most of the countries. Fermented soybean meal supplementation can enhance pig growth performance of which the enhancement in feed efficiency is due to the improvement in nutritional value and availability rather than feed intake.The gut microbiota plays a crucialrole in livestock health and disease. Hence, it is necessary to find a mechanism to remove anti nutritional factors along with improved intestinal microbiota thereby producing improved production performance and reduced diarrhoea in piglets. The main objective of this review is to discuss the benefits of feeding fermented soybean meal in piglets.

Growing dogs were fed diets containing soy oil or poultry fat as the main fat source and soybean meal or meat meal as the main protein source to examine the effects of types of dietary fat and protein on fatty acid concentrations in serum and skin and on serum cholesterol concentrations. Dogs fed diets containing soy oil had higher serum linoleic acid concentrations and lower serum oleic acid, arachidonic acid, and cholesterol concentrations than dogs fed diets containing poultry fat. The type of dietary protein had marginal effects on fatty acid concentrations and did not affect serum cholesterol. Similar differences were found in cutaneous fatty acid concentrations, with soy oil-fed dogs having significantly (P < 0.05) higher linoleic acid and lower oleic acid concentrations in their skin than had poultry fat-fed dogs. This study suggested that dietary fat source influences serum and cutaneous fatty acid concentrations and serum cholesterol concentrations in dogs, irrespective of dietary protein source.

A study was conducted to evaluate the effects of feeding processed kidney bean meal (PKBM) by replacing soybean meal (SBM) on fertility, hatchability, embryonic mortality and chick quality of white leghorn (WL) hens. A total of 225 white leghorn hens (195 layers and 30 cocks) with uniform body weight (BW) and age were randomly distributed into 15 pens and assigned to five treatments (i.e., T1, T2, T3, T4, and T5). A total of 360 eggs collected from all the treatment birds were used for the analysis. The feeds of the treatments were SBM substituted by PKBM at 0, 25, 50, 75 and 100% levels for T1, T2, T3, T4, and T5, respectively. Replacement of SBM with PKBM in the diet did not affect the fertility, hatchability, embryonic mortality, chick length, chick weight, and chick quality by visual score. As no difference is observed, 100% replacement of SBM by PKBM (dosed at 100 g/kg concentrate diet) is possible.

The aim of the study was to evaluate the effect of feeding two levels of crude protein (CP) (low: 142 g CP/kg DM; and high: 156 g CP/kg DM) and two nitrogen sources (soybean meal and urea) to dairy cows using sugar cane as forage on microbial protein synthesis, the composition of the milk nitrogen fraction, nitrogen (N) balance and blood parameters. Twelve Holstein cows with an average milk yield of 22.0 ± 2.3 kg/day, and with 235 ± 40 days in milk were included in this study. The animals were grouped into three balanced and contemporary 4x4 Latin squares for an experimental period of 21 days. On the 15th day of each period, milk and urine samples were collected for microbial protein synthesis determination. Total excretion of urine (L/day), milk urea nitrogen (MUN) and blood urea were higher for the diets with high CP, regardless of the nitrogen source. Nitrogen efficiency was higher for cows fed diets with low CP. Cows in the final third of lactation can be fed diets with reduced CP levels, regardless of the nitrogen source, soybean meal or urea, without influencing the synthesis of microbial protein or the composition of the nitrogen fraction of milk.

Foram utilizadas 12 vacas Holandesas com produção média de 22,0 ± 2,3 kg leite/dia, no terço final de lactação (235 ± 40 dias em lactação), agrupadas em três quadrados latinos balanceados e contemporâneos 4x4, com período experimental de 21 dias, dos quais 14 para adaptação as dietas e os demais para coleta de amostras. A excreção total de urina (L/dia), o NUL e a ureia sanguínea foram maiores para as dietas com alta PB, independentemente da fonte nitrogenada. A eficiência de utilização do N foi maior para as vacas alimentadas com dietas com baixa PB. Vacas no terço final da lactação podem ser alimentadas com dietas com teores reduzidos de PB, independentemente de a fonte nitrogenada ser farelo de soja ou ureia, sem influenciar a síntese de proteína microbiana, a composição da fração nitrogenada do leite e obter maior eficiência de utilização do N da dieta.
