“…One of the possible explanations for the linear reduction in the observed concentrations of milk protein, according to the inclusion of protected fat in diets, can be related to the reduction in rumen fermentable organic matter; this effect may be caused by the replacement of fermentable starch from corn by a fat with high intestinal digestibility, which decreases the available energy for rumen fermentation (Geron et al, 2011). This process reduces microbial protein synthesis in the rumen, which is the main source of metabolizable protein that is needed for milk protein synthesis (Santos;Pedroso, 2011).…”

According on the fat source included in the diets for goats, the milk production can be increased and milk fatty acid composition can be improved. This study was conducted to evaluate the inclusion of protected fat (CSFA - calcium salts of fatty acids) in the diets of lactating Saanen goats on milk production and composition. Five Saanen goats (63.23 ± 9.08 kg body weight and 105 ± 3 days of lactation) were distributed in a Latin square design (5 × 5) with five diets: control (without the addition of CSFA) and the other diets with: 6.25, 12.50, 18.75 and 25.0 g CSFA per kg dry matter (g/kg DM), respectively. Dry matter intake (DMI) and milk production (MP) were evaluated. Milk samples were collected to determine milk composition and fatty acid profile. Feed efficiency (FE) was estimated. The supplementation of CSFA up to 25 g/kg DM did not influence the DMI, MP and FE. Milk components production (g/d) was not influenced by the inclusion CSFA in the diet; however, there was a linear reduction of 0.87 g protein per kg of milk for each 1% CSFA included in the diet. The concentration of linolenic acid (18:3n-3) in milk was improved with a maximum point of 24 g of CSFA per kg DM. CSFA can be included in the diets of lactating Saanen goats up to 25 g/kg DM with no interference on DMI and MP.

“…Most, however, can be used in ruminant feed, which reduces production costs and transforms residue materials of low nutritional content into market products with high value, such as meat and milk. The use of agro-industry residues as alternative foods facilitates livestock production and reduces the problems caused by the disposal of residues in the environment (GERON et al, 2011).…”

<p>This study measured the ruminal parameters, feed intake, fecal and urinary N production, and N balance (NB) in sheep fed increasing levels of residue from the extraction of tamarind pulp (RETP) on a 0.0%, 5.0%, 10.0%, and 15.0% dry matter (DM) basis. Four mixed-breed male sheep weighing 40.38 ± 2.10 kg of body weight were distributed in a 4 × 4 Latin square design. The animals were allocated to metabolism cages and fed twice a day. Each experimental period lasted 20 days. The pH and concentration of ammonia nitrogen (NH3-N) in ruminal fluid were measured. Nitrogen intake (NI), fecal N (FN), urinary N (UN), absorbed N (AN), and NB were expressed in g·day-1, percentage of consumed nitrogen (CN), and g·kg-1 of metabolic weight (g·(kg0.75)-1. Statistical analysis of these variables was performed by evaluating the variance and regression at 5% probability. The levels of RETP did not alter (p>0.05) the pH level or NH3-N concentration in the rumen fluid, but a quadratic behavior for the same values after feeding (p<0.05) was observed. The inclusion of RETP in the diet did not change (p>0.05) NI, UN, the AN in g·day-1 and g·(kg0.75)-1, NB in g·day-1 and g·(kg0.75)-1, or the percentage of CN. However, the AN as a percentage of CN showed a linear effect (p<0.05) with the inclusion of RETP in experimental diets. For FN in g·day-1 and g·(kg0.75) -1, no difference was observed (p>0.05) with the inclusion of RETP, but for FN expressed as a percentage of CN, a linear increase (p<0.05) was observed with the inclusion of RETP. Thus, we concluded that diets with up to 15.0% RETP do not alter the pH and NH3-N in ruminal fluid, NI, UN, or NB. In addition, the inclusion of 15.0% RETP has a laxative affect. </p>

“…According to Geron et al (2011), alternative foods, including organic residues, can improve the efficiency of the production systems of small and medium ruminants. The use of non-traditional food sources from agribusiness, including RETP in ruminant feed, can change the dynamics of ruminal fermentation.…”

This study evaluated the digestibility of nutrients by, and parameters associated with, in vitro fermentation using different inocula (sheep ruminal fluid and feces) as well as the in vivo digestibility in sheep that were fed rations with 50% concentrate containing either no (0%) residue from the extraction of tamarind pulp (RETP) or 15% RETP. To determine the in vitro digestibility (IVD) of nutrients, two sheep, weighing 40.38 ± 2.10 kg, were used as inoculum donors. To determine the in vivo digestibility of nutrients, we used four sheep and a 3×2 factorial experimental design, with three methods of digestion of nutrients and two experimental rations (0% and 15% RETP). The variables were subjected to analysis of variance and the variables that showed differences at 5% probability were further analyzed using the Tukey test at 5% significance. The IVD using different inocula did not significantly differ (p>0.05) from the in vivo digestibility in sheep for dry matter (DM), organic matter (OM), and neutral detergent fiber (NDF). The different methods for determining nutrient digestibility did not affect (p>0.05) the digestibility of DM, OM, crude protein (CP), NDF, and acid detergent fiber (ADF) in rations with 0% and 15% RETP. However, the IVD of CP for rations containing 0% and 15% RETP incubated with both inocula was lower (p<0.05) than the CP digestibility in vivo. The in vivo digestibility of ADF for rations containing 0% and 15% RETP was higher (P<0.05) than the IVD using sheep ruminal fluid and feces as inocula. The pH values and concentration of ammonia nitrogen (NH 3 -N) after in vitro incubation for 24 h and the in vivo assay were not different (p>0.05) for the rations containing 0% and 15% RETP, but the pH and NH 3 -N of both fermented and rumen contents differed (p<0.05) depending on the inocula used and the in vivo assay. In summary, the digestibility of DM, OM, and NDF can be determined by the in vitro fermentation method using the ruminal fluid or feces of sheep as inocula in rations containing 0% or 15% RETP. However, in vitro fermentation is not a suitable method for the determination of pH and NH 3 -N concentration. ResumoAvaliou-se a digestibilidade de nutrientes e os paramentos da fermentação in vitro com diferentes inóculos (líquido ruminal e fezes de ovinos) e in vivo em ovinos de rações com 50% de concentrado contendo 0% (ausência) ou 15% de resíduo da extração da polpa de tamarindo (REPT). Para a determinação da digestão in vitro dos nutrientes foram utilizados dois ovinos com peso corporal médio de 40,38 kg ± 2,10 kg, como doadores de inóculo e para a determinação da digestibilidade in vivo dos nutrientes foram utilizados quatro ovinos por tratamentos distribuídos em duas rações experimentais com 0% e 15% de REPT. O delineamento experimental foi fatorial 3X2, três métodos de digestão dos nutrientes e duas rações experimentais com 0 e 15% de REPT. As variáveis estudadas foram submetidas à análise de variância e para as variáveis que apresentaram diferença a 5% de probabilidade proce...
