O desafio de ampliação do mercado do leite de cabra tem estimulado ações de pesquisa, desenvolvimento e inovação para desenvolvimento de alimentos diferenciados. Uma das alternativas é a produção de lácteos com alto teor de ácido linoleico conjugado (CLA) e alegação funcional. O presente trabalho sintetiza os achados de pesquisa em rede, envolvendo uma equipe multidisciplinar de pesquisadores com o objetivo de desenvolver bases para a produção de alimento lácteo caprino com alto teor em CLA e alegação funcional. Os resultados obtidos indicam que a suplementação da dieta com óleo de soja, tem sido a melhor estratégia para a obtenção de um leite com alto teor de CLA, sem prejuízos à produção animal. Este teor de CLA permanece inalterado quando o leite é...

Objective: To investigate the effects of lipids from goat milk containing conjugated linoleic acids on body weight and reflex ontogeny of neonatal rats treated during the prenatal and suckling periods. Methods: Three groups were studied: soybean oil (S), coconut oil (C), and goat milk lipids (GM). Reflex maturation (palm grasp, righting reflex, cliff avoidance, vibrissae placing, negative geotaxis, auditory startle, and free-fall righting) as well as body weight evolution were recorded during lactation. Results: Data demonstrated that the lipids from goat milk accelerated body weight evolution as well as all the reflex maturation investigated (P < 0.05). Discussion: The supply of goat?s milk offered to Wistar rats during pregnancy and lactation provided...

The aim of this study was to evaluate the performance of cows fed with a total mixed ration composed of elephant grass and a concentrate containing 0.0% (control), 1.5%, 3.0% or 4.5% soybean oil on a dry matter basis. The effect of milking time (morning versus afternoon) on butter fatty acid composition was also evaluated. Twelve multiparous Holstein x Gyr cows with an average milk production of 18.0±4.6 kg day-1 and 90±25 days in milk were used in a triplicated 4 x 4 Latin square experimental design with 15-day periods. Data were analyzed using mixed models. There was no effect of soybean oil supplementation on dry matter or neutral detergent fiber intake (P > 0.05). The fat-corrected milk yield linearly decreased (P=0.0109) and the milk protein yield...

This study evaluated the chemical and lipid composition of uncooked or cooked loin (Longissimus thoracis) and rump (Biceps femoris) in samples of 2.54 cm thick from 35 carcasses of Nellore young bulls finished in feedlot for 96 days and slaughtered at an average weight of 532.17 ± 30.25 kg and 24 months of age. The rump had the lowest level of protein and ash (18.57 and 0.90%, respectively) and the highest level of ether extract compared to loin (3.37 and 1.90%, respectively). Higher levels of cholesterol were found in rump compared to loin (40.91 e 30.93 mg 100 g-1, respectively). The uncooked loin showed lower content of saturated fatty acids and higher content of polyunsaturated fatty acids. The best values for the omega-6: omega-3 ratio was observed in...

Fatty acid (FA) content affects the sensorial and nutritional value of meat and plays a significant role in biological processes such as adipogenesis and immune response. It is well known that, in beef, the main FAs associated with these biological processes are oleic acid (C18:1 cis9, OA) and conjugated linoleic acid (CLA-c9t11), which may have beneficial effects on metabolic diseases such as type 2 diabetes and obesity. Here, we performed differential expression and co-expression analyses, weighted gene co-expression network analysis (WGCNA) and partial correlation with information theory (PCIT), to uncover the complex interactions between miRNAs and mRNAs expressed in skeletal muscle associated with FA content. miRNA and mRNA expression data were...

The changes in the concentration of trans-vaccenic (C18:1t-11) and rumenic (C18:2c-9,t-11) acids in the milk from cows grazing on Pennisetum clandestinum, fed a supplement containing palm oil, rice bran or whole cottonseed were evaluated. Three supplements were assessed: one control supplement containing palm oil (C), with a low concentration of linoleic acid mainly from palm oil, and two supplements containing rice bran (RB) or whole cottonseed (CS) as the main source of linoleic acid. Six Holstein cows (4.2±1.7 years of age, 532.5±50.7 kg BW, 125±29 days in milk and a milk yield of 21.7 5.8 kg d−1; Mean±SD) were assigned to each treatment using a double 3 × 3 × 3 Latin Square Design. Compared with treatment C, the milk fat concentrations of...

Dietas bajas en proteína adicionadas con ácido linoleico conjugado o aceite de soya acidulado para cerdos en engorda

Reducir la concentración de proteína en las dietas de cerdos adicionando aminoácidos sintéticos mantiene la respuesta productiva, pero la carne tiene un mayor contenido de grasa. El uso de distinto aceite en la dieta de cerdos puede modificar este aspecto; además, de cambiar el contenido de ácidos grasos en la carne por aumento en el consumo de ácidos grasos que no son sintetizados por los cerdos. Se realizaron tres experimentos para evaluar dietas bajas en proteína y distinta fuente de aceite (aceite crudo de soya “ACS”, ácido linoleico conjugado ”ALC” y aceite de soya acidulado “ASA”) en cerdos de engorda. El experimento 1 y 2 fueron pruebas de comportamiento productivo y evaluación de las características de la canal en las dietas de inicio, crecimiento...

To analyze the effect of conjugated linoleic acid (CLA) on the meat of pigs (0,1%) and three crude protein (CP) levels (nursery: 20.5, 16.0, 14.5%; growing: 16, 14.5, 11.5%; and finishing: 14.0, 12.5, 11% CP), studies were conducted with 36 hybrid (Yorkshire×Landrace×Duroc) barrows (17.3-83.5 kg), which were individually penned and allotted in a completely randomized design in a factorial (2×3) arrangement for 84 d. The analysis by phases indicated that CP level affected some variables. Average daily gain, average daily feed intake, fat free lean gain, backfat thickness, longissimus muscle area and final body weight were reduced (P≤0.05) feeding the lowest CP diet in nursery and growing pigs. Plasma urea nitrogen concentration was also lower (P≤0.05) in...

Abstract The inclusion of plant oils in the diets of grazing cows represents a promising nutritional strategy for the production of milk naturally enriched with bioactive compounds, such as rumenic (cis-9, trans-11 CLA), vaccenic (trans-11 C18:1) and oleic (cis-9 C18:1) acids. The aim of this study was to evaluate the effect of dietary supplementation with sunflower oil (SO) on the fatty acid (FA) composition of milk from Holstein x Gyr dairy cows grazing on Urochloa brizantha cv. Marandu under rotational stocking. Sixteen multiparous cows with 185±10 days in milk received a concentrate containing 0% (control) or 15% SO on a dry matter basis in a randomized block design with two replications (paddocks). The results were analyzed with mixed models (P ?...

Abstract: Goat milk is source of different lipids, including conjugated linoleic acid (CLA). CLA reduces body fat and protect against cardiovascular diseases. In the present study fat from goat milk naturally enriched with CLA was used. Male Wistar rats were divided into three groups that received during a 10 week diet with different lipid sources: soybean oil (CON), coconut oil (CO) and goat milk fat naturally enriched with CLA (GM-CLA). We evaluated the effects of a GM-CLA on biochemistry parameters--high density lipoprotein (HDL), triacylglycerol (TAG), TAG/HDL ratio, total cholesterol and glucose, body weight and histopathological aspects of the intestine and liver. GM-CLA increased body weight from the second to the fifth week of the experiment...

The objective in this study was to determine growth, carcass characteristics, chemical composition and fatty acid profile of the longissimus dorsi of crossbred Boer × Saanen kids fed castor oil. Twenty-four kids (12 males and 12 females) were assigned in a randomized complete block design with two treatments and twelve replications. Blocks were defined according to weight, gender and initial age of animals for the evaluation of performance. The experimental treatments consisted of two diets containing 900 g concentrate/kg: a control diet (without addition of oil) and another containing castor oil at 30 g/kg (on a dry matter basis). After they reached an average body weight of 25 kg, males were slaughtered for the evaluation of carcass characteristics,...
