“…Rapeseed meal (RSM), having 32%-40% crude protein [5] , ranks second (12% of total) in global oilseed meal consumption [2] . Sunflower meal (SFM), containing 28%-30% protein, 25%-27% cellulose, and 11%-13% lignin (dry basis) [6] , is considered a potential protein source for ruminants with high-fiber content [7] . Cottonseed meal (CSM) is rich in protein from 30% to 50% in dry matter [8] .…”

Reasonable design of the parameters of thermal processing such as conditioning and cooling according to formula changes of pelleted feeds has always been a serious challenge for Chinese feed mills and feed equipment manufacturers. Studying the thermophysical properties of different protein feeds under different temperatures and particle sizes will facilitate the equipment design, parameter optimization, and simulation for the thermal processing of pelleted feeds. In this study, the specific heat (C p ), thermal conductivity (k b ), and thermal diffusivity (α) of six plant protein supplements with three particle sizes were determined over a temperature range of 25°C-100°C. The differences in C p , k b , and α among different feedstuffs and particle sizes were analyzed and the influences of temperature and particle size on these properties were evaluated. Results showed that the C p , k b , and α of all the feedstuffs increased with increasing temperature and varied from 1.622 to 2.417 kJ/(kg•°C), 0.080 to 0.362 W/(m•°C), 6.379×10 -8 to 21.984×10 -8 m 2 /s, respectively. To rise to the same temperature, the distiller's dried grain with solubles (DDGS) needed to absorb 3% more heat than that required for soybean meal (SBM), while the rest four feedstuffs just needed to absorb 93%-98% heat for SBM. Particle size had no significant effect on C p for all the feedstuffs (p>0.05). However, descending trends in k b and α were observed with increasing particle size for a certain feedstuff at the same bulk density. In addition, regression equations with only statistically significant terms were developed to describe C p , k b , and α as a function of temperature and particle size for six feedstuffs. The results can provide basic theory and data for the optimization of thermal processing parameters required for the plant-protein ingredient change in compound feed formulations.

“…It is well known that dietary fat may influence the fat content of ewe milk and biochemical parameters of their blood. In recent years, consumers are becoming more conscious of the link between diet, disease, and food components and how they can influence health status (Goes et al, 2017).…”

Partial replacement of soybean meal with pea grains and sunflower cake in ewe diets: milk quality and blood biochemical parameters

et al. 2019

The objective of this research was to evaluate the effect of pea and sunflower cake as partial replacement for soybean meal in diet, as well as to assess their effect on milk quality during lactation and on blood parameters of ewes kept in organic farming. The research was carried out with 30 ewes of Merinolandschaf breed during 75 days. Ewes were given mixtures based on soybean meal as a protein source in control group (SBM), while in experimental groups, soybean meal was partially replaced with pea grain (P) and sunflower cake (SFC). Biochemical parameters (urea, glucose, total protein, albumin, globulins, cholesterol, HDL, LDL, triglyceride, β-hydroxybutyrate, and non-esterified fatty acids), as well as enzyme activity (ALT, AST, ALP, GGT, and CK) were determined in blood of ewes. Milk composition and concentration of fatty acids in milk fat were also determined. In comparison with control, sunflower cake as a protein source affected the increase of fat content in milk. When compared with pea grain and SBM, it decreased the urea concentration in milk. Oleic acid, total monounsaturated fatty acids, and n-6 increased, while saturated fatty acids, atherogenic, and thrombogenic indices decreased in SFC. Feeding ewes with peas increased the content of n-3 fatty acids in their milk. If compared to SFC, it also improved the n-6:n-3 ratio. Partial replacement of soybean meal with SFC reduced the blood concentration of total protein, globulin, and AST, and GGT enzyme activities and increased the β-hydroxybutyrate. Inclusion of pea grain and SFC can be adequately used as partial replacement of soybean meal in feeding of ewes kept in organic farming.
