“…In the South, Southeast, and Midwest regions of Brazil, there has been a significant increase in the production of dairy sheep due to several favorable factors such as fertile soil, mild climate, and topography, as well as a new niche of consumers searching for different, flavorful, and healthy foods like sheep milk and its derivatives (Bianchi et al, 2014a).…”

The objective of this study was to evaluate the effect of protected fat from palm oil on body weight and milk production and composition of lactating Lacaune ewes. Four treatments (0, 20, 40, and 60 g kg −1 as fed) of protected fat from palm oil were used to feed nine animals in each group. Isoproteic and isoenergetic diets were formulated and adjusted for each animal after milk weighing. Corn silage was used as roughage on the same proportion of concentrated to feed all animals. Milk samples were collected weekly for chemical analyses up to the seventh week of the lactation period and every other week after that until the end of the lactation period (182 days). Increased levels of protected fat in the diet of lactating ewes resulted in lower body weight gain and poor animal body condition. The production peak showed differences and was higher in the treatment of 40 g kg −1 of palm oil, but milk production during lactation was higher in animals that received 60 g kg −1 of protected fat supplementation. Animals fed 60 g kg −1 of protected fat showed the highest milk yield. We observed a positive linear effect on milk fat content, whereas the effect on milk protein, lactose, and nonfat solids was linearly negative after dairy sheep fed protected fat from palm oil. There were no changes in the amount (kg) of milk fat, protein, lactose, total solids, and nonfat solids in any of the treatments. Therefore, protected fat from palm oil is efficient to increase milk production and fat content.

“…For instance, Elaeis guineensis oil contains approximately 50% of saturated and 50% of unsaturated fatty acids. Palm oil is rich in tocotrienol, a form of vitamin E beneficial to health in general (Bianchi et al, 2014a). The use of fat is an effective method to increase dietary energy density.…”

“…The capacity of the immune system is vital for health during fattening, of which the level not only affects the daily weight gain but also the disease incidence. In the last few years, several studies have investigated the strong relation between nutrition and immune response in livestock production, particularly in dairy cows [ 29 , 30 , 31 ] and sheep [ 32 , 33 ]. We measured an index of the immune system for appreciating the mixture diets with the same nutrition concentration.…”

“…The results of all the index were not statistically different among the treatments, and illustrate that different compositions of straw did not affect the immune function. Meanwhile, the serum immunoglobulin levels (IgG, IgM, and IgE) and proinflammatory cytokine levels (TNF-α, IL-1, and IL-6) significantly increased on days 60 and 120 ( p < 0.05) in a diet based on palm oil [ 33 ]. The previous study demonstrated that the diet supplementation linseed and quinoa enhanced the cell-mediated immune response of lambs [ 32 ].…”

As the byproduct of finger millet, millet straw is a new forage resource of ruminants. The effect of the combined utilization of millet straw with corn straw on fattening lamb production is seldom reported. The purpose of this study was to investigate the effect of different proportions of millet straw instead of corn straw on the growth performance, blood metabolites, immune response, meat yield, and quality of fattening lamb. Sixty-three-month-old healthy Small-Tailed Han sheep crossbred rams with an average initial weight of 19.28 ± 2.95 kg were randomly divided into four groups, with three replicates in each group and five lambs in each replicate. The replacement ratio of millet straw of each group (Group I, II, III, IV) was 0%, 25%, 35%, 50% at the first stage (the first two months) and 0%, 20%, 28%, 40% in the second period (final two months), respectively. The experiment lasted 4 months 10 days of the pre-feeding period. The results indicated that the body weight gain and average daily gain of group Ⅱ were significantly higher than those of group Ⅰ and group Ⅳ (p < 0.05). The concentration of total protein in group Ⅳ was significantly increased compared to those of the other three groups at the second stage (p < 0.05), which proved that the protein synthesis metabolism capacity was improved with the addition of millet straw. The concentration of the plasma glutamic-oxalacetic transaminase and lactic dehydrogenase of lambs was significantly decreased in group Ⅱ (p < 0.05). The combination of millet straw and corn straw had no impact on the glucose, total cholesterol, and triglycerides metabolism (p > 0.05). There was no significant difference in the pre-slaughter weight, carcass weight, dressing percentage, loin-eye area, and GR value among the four groups (p > 0.05). Furthermore, the immune response and meat quality were not impacted by the different proportions of millet and corn forage diets. The results showed that the combined utilization of millet straw with corn straw could improve the blood biochemistry metabolism capability of fattening lambs. The replacement of 50% of corn straw with millet straw could improve the growth performance and be an application in fattening lamb production.

“…Moreover, alpha-and beta-carotene are primarily precursors of vitamin A, essential for preventing blindness, maintaining tissue integrity, and promoting growth (Wattanapenpaiboon & Wahlqvist, 2003) while tocochromanols are potent antioxidants that confer oxidative stability to the oil (Nagendran, Unnithan, Choo, & Sundram, 2000). Palm oil as compared with other plant fats is especially characterized by high levels of tocotrienols that have shown valuable biological properties in cancer prevention, protection against cardiovascular diseases, neurodegeneration, oxidative stress, and immune regulation which has been confirmed in many studies around the world (Bianchi, Macedo, Duarte, et al, 2014;Meganathan & Fu, 2016), but only 1% of vitamin E research refers to tocotrienols (Wong & Radhakrishnan, 2014).…”

Study on the influence of palm oil on blood and liver biochemical parameters, beta-carotene and tocochromanols content as well as antioxidant activity in rats

In the ongoing discussion on the health properties of palm oil, a study of the effect a diet supplemented with palm oil on blood and liver biochemical parameters, beta‐carotene and tocochromanols content as well as antioxidant activity was undertaken. Forty Wistar rats were randomly divided into five groups, fed with a diet supplemented with plant‐based frying commercial fat, palm oil, 7.5% palm oil and 2.5% concentrate from palm oil and 10% of rapeseed oil, respectively. After 21 days, blood samples and livers were collected to determine beta‐carotene and tocochromanols concentrations, antioxidant activity using DPPH* radical scavenging activity and TEAC methods, insulin, glucagon, serum triacyloglycerols and cholesterol levels, glucose in blood serum and glycogen in the livers. Research has shown valuable biological properties of palm oil in terms of plasma glucose, total cholesterol, low‐density lipoprotein (LDL) cholesterol, and triacylglycerol concentrations which was related to the high content of beta‐carotene and tocochromanols. Practical application Public concern over the health properties of palm oil has been growing. Therefore, this study supplements existing knowledge in this area based on experimental rat observations. In the presented research, plasma glucose was significantly reduced and no additional growth of total or LDL cholesterol, as well as triacylglycerol concentration, was observed after consuming a palm oil‐based diet. Palm oil was a good source of beta‐carotene and tocochromanols, which were preferentially distributed in rats’ livers. Bioavailability of vitamin E‐active compounds in palm oil supplemented rats’ livers was relatively high as compared to the rapeseed oil group, therefore this observation complements literature in the field of tocotrienols and tocopherols. Studies have not confirmed the harmful effect of palm oil on rats, however in depth human studies appear to be a promising direction for further research.
