Abstract This study evaluated the effect of roughage:concentrate (R:C) ratio associated with a variable particle size of physically effective neutral detergent fibre (peNDF8) in the forage (Tifton-85 hay) on the performance, carcass traits and meat quality of lambs. Seventy-two 4-month-old, non-castrated Santa Ines male lambs (23.5 ± 2.32 kg BW) were distributed in a completely randomized design, in a 2 × 2 factorial arrangement [two peNDF8 hay particle sizes (13 and 6 mm) and two R:C ratios (700:300 and 500:500 g/kg DM total)]. DMI, DM, NFC and TDN digestibility's, N-intake and N-faecal excretion were affected by the R:C ratio (P < 0.05). However, the N-retained was not affected by the studied variables (P > 0.05). It was observed an interaction (P < 0.05) between the peNDF8 and R:C ratios for final BW, average daily gain (ADG), colour parameters and pH 24 h. The lower roughage ratio provided greater (P < 0.05) concentrations of C14:1, C16:1–cis9, C18:1–cis9, ΣMUFA, Σn–6:Σn–3 and hypocholesterolemic/hypercholesterolemic index, enzymatic activity Δ9desaturase-C16 and -C18. Lambs fed a lower roughage diet had improved performance and feed efficiency, however, presented reduced polyunsaturated fatty acids (PUFA) concentrations in the meat, especially Σn–3 family. Higher roughage diet and larger peNDF8 particle size improved the concentrations of PUFA while decreased Σn–6:Σn–3 ratio in meat. Larger peNDF8 particle size associated with higher roughage proportion, have reduced animal performance however, it increased protein concentration, a* and C* colour parameter without affecting fatty acids profile of Longissimus lumborum muscle.

Alkaline Catalysis

This study aimed to the methyl biodiesel production by transesterification reaction via alkaline catalysis, using as a raw material alternative to soybean oil commonly used, coco-da-baía oil (Cocos nucifera L). The biodiesel was characterized as to its acidity, density, humidity, ester content, flash point, glycerol (free, total, mono-, di- and triglycerides) and maximum percentage of methanol. The oil used was characterized by acid value, saponification number, fatty acids, density and humidity. Through these results, we verified the quality of the obtained biofuel.

Intramuscular Fat Content

The aim of this study is to compare two sheep farming practices (lamb farming with or without finishing period on concentrate), on carcass characteristics, fatty acid profile and organoleptic quality of the meat. The study was performed on 24 Beni-Guil lambs. Finished animals (F) had access to creep feeding until weaning and were fed a mixed ration of barley and alfalfa hay during a finishing period of 45 days; however, nonfinished animals (NF) remained on the pasture. This comparison was carried out by analyzing the carcass characteristics, proximate composition and fatty acids profile of the meat. Ultimate pH and meat lightness were lower for F-lambs than NF-lambs who didn’t go through the finishing period. The concentrate-based finished practice produced carcasses with better fatness state and conformation. The intramuscular fat content is more important in finished-lambs’ meats (3.81 vs 1.82) which show more juiciness and a high meat’s color lightness. However, meats of NF-lambs presented a high proportion of polyunsaturated fatty acids (PUFA: 20.70 vs 16.82), particularly the PUFA n-3 (3.97 vs 1.17) and consequently a low n-6/n-3 ratio (3.92 vs 12.72). Finally, we recommend, finished lamb meats for the large-scale market and meat of pasture-raised lamb for the niche market.

Randomized Design

This study was carried out to evaluate the effects of increasing metabolizable energy and soybean oil levels on the egg chemical composition, total lipids and cholesterol contents and fatty acids profile in the egg yolk. Three hundred and sixty 29 week-old Bovans Goldline semi-heavy commercial layers were used during three periods of 28 days. A completely randomized design were used in a 3 × 3 double factorial arrangement with three soybean oil levels (1, 2 and 3%) and three metabolizable energy levels in the diet (2,600, 2,750 and 2,900 kcal/kg), totalizing nine diets with five replicates of eight birds. No interaction soybean oil × metabolizable energy levels was observed. The metabolizable energy levels did not affect any of the determined characteristics. The moisture, ash and protein contents in the egg yolk and albumen and the lipid and cholesterol contents in the yolk were not affected by the soybean oil levels in the diet, while linoleic acid (C18:3) and linolenic acid (C18:2) levels responded linearly. The use of 2,600 kcal ME/kg and 3% of soybean oil in the diet of laying hens with consumption of 120 g/bird/day is justifiable, since this feeding strategy improves the fatty acids profile of the egg.

Quality Of Milk

This bibliography review analyzes the effects of different feeding regimes of cows the nutritional and sanogenic quality of milk, with a particular emphasis on milk content in functional fatty acids and non-enzymatic lipophilic antioxidants. Thus, using suitable feeding regimes of cows, fatty acid (FA) profile of milk fats can be improved by increasing the concentration in functional FA (C18:1 trans-11, vaccenic acid; C18:3 n-3, acid linolenic and C18:2 cis-9 trans-11, isomer of conjugated linoleic acid), considered as beneficial for consumer’s health. These suitable feeding regimes of cows aim using green fodder (pastures), preserving the fodder by drying or silage, supplementing the food with fats rich FA polyunsaturated (PUFA) and ensuring an optimal ratio between volume and ration concentrates. Milk yielded from grazing cows shows a considerably higher concentration of functional FA and lipophilic antioxidants (tocopherols, retinol and carotenes) and a lower content of saturated FA compared to that yielded from cows fed in shelter with TMR (total mixed ration). Also, hay-based feed rations, mainly those containing small amounts of concentrates or those supplemented with vegetable fats, ensure a milk yield with a fatty acid profile more favorable for human health and a better oxidative stability of compared to those with feed-based rations on silage or those high in concentrates.
