The influence of modifying a traditional 24-mo dairy steer calf to beef production system on the fatty acid composition of the longissimus muscle and its potential to authenticate beef provenance was examined. Fifty-four male calves (n = 18 per sire breed), progeny of Holstein-Friesian cows mated with Holstein-Friesian (HF), Aberdeen Angus (AA) and Belgian Blue (BB) bulls were at pasture from March until August of their second year when they were assigned to a 3 (breed types) × 3 (finishing strategies) factorial experiment. The three finishing strategies were (i) pasture only for a further 94 d prior to slaughter (21 mo of age) (Grass), (ii) concentrates ad libitum indoors for 94 d prior to slaughter (21 mo of age) (EC) and (iii) pasture only for a further 94 d followed by concentrates ad libitum indoors for 98 d prior to slaughter (24 mo of age) (LC). Compared to EC, muscle from Grass had a lower intramuscular fat concentration and omega-6: omega-3 polyunsaturated fatty acid (PUFA) ratio and higher proportion of conjugated linoleic acid. A longer period at pasture pre-concentrate finishing increased the concentration of omega-3 PUFA which was still lower than in Grass. To maximise the omega-3 PUFA concentration, a late-maturing breed is more appropriate while to maximise conjugated linoleic acid, an early-maturing breed is more appropriate and both should be finished on grass. Chemometric analysis confirmed that the fatty acid profile can authenticate “Grass-Finished” beef per se and has potential to distinguish “Concentrate-Finished” beef based on the length of grazing prior to finishing, but not distinguish between sire breeds.

Cheese Production

Summary Organic farming represents agricultural practice that could contribute to the preservation of biological diversity and breeding of cows with the most desired milk quality attributes. Milk composition could vary widely according to genetic diversity of the animals and different feeding systems. These are related to higher dry matter content, fat, protein and a more favorable ratio of the saturated/unsaturated fatty acids, which is important in traditional cheese production. Standard chemical analyzes were performed and this paper shows the differences in the chemical properties and the fatty acid profile of milk, depending on the different breeds and breeding methods of animals. Simmental milk (indoors) was most abundant in dry matter and fat (13.01 and 4.30%, respectively) while protein and casein level was the highest in the Busha milk (3.67 and 2.63%, respectively). Holstein Friesian milk (organic) possessed a more constant composition and, together with Busha appropriate hygienic quality of milk (low level of somatic cells and total bacteria count). Also, milk from Holstein Friesian cows (organic) was disposed with better nutritional quality and more desirable fatty acid profile (SFA (63.40%), MUFA (30.79%) and PUFA (5.72 %)). On the other hand, Holstein Friesian (conventional) milk contained SFA (67.45%), MUFA (29.27%) and PUFA (3.28%) while Simmental (indoors) higher values of SFA (71.21%) and less MUFA (25.39%) and PUFA (3.40%). There are various ways to preserve biodiversity and the application of organic production standards in the traditional cheese production contributes to obtaining safer, quality products which are more recognizable on the market.

Abstract The aim of this study was to determine the effect of Virginia fanpetals (Sida hermaphrodita) silage on the fatty acid profile and the content of selected nutrients and vitamins in the Longissimus lumborum (LL) and Semimembranosus (SM) muscles of young bulls. Forty Polish Holstein-Friesian bulls aged 16 months were assigned to four dietary treatments (n=10) and were fed different types of silage during a 7-month fattening period. The proportion (g/kg dry matter) of silage in the diets was as follows: (1) grass silage (GS) (600); (2) Virginia fanpetals silage (VFS) (600); (3) VFS (300) and GS (300); and (4) VFS (300) and maize silage (MS) (300). Silage was supplemented with concentrate at 400 g/kg DM in each diet. The animals were slaughtered at the end of the fattening period. The intramuscular fat (IMF) of bulls fed GS had the highest (P<0.05) concentrations of n-3 polyunsaturated fatty acids (PUFAs) and linolenic acid (LNA), whereas the IMF of bulls receiving GS and VFS was characterized by the highest proportion of MUFAs, mostly oleic acid (C18:1 cis 9). In comparison with the LL muscle, the SM muscle contained less IMF (by 40%) with a more nutritionally desirable profile. The SM muscle was characterized by a more desirable mineral composition and a higher concentration of α-tocopherol.

Context Using legumes in ruminant production system may provide benefits such as improvement in animal performance and decrease in methane (CH4) emissions, mainly based on nutritional characteristics of these plants and the presence of tannins. Macrotiloma (Macrotyloma axillare) is a tropical legume that still lacks studies regarding its effects on animal performance and CH4 emissions. Aims The objective of this experiment was to evaluate productive performance, CH4 emission, ruminal fermentation parameters, carcass characteristics and fatty acid profile of the meat from lambs fed tropical grass hay supplemented with the legume forage macrotiloma. Methods For a 90-day experimental period, 14 Santa Inês male lambs (aging 100 days; 18.06 ± 3.26 kg initial bodyweight) were allocated in individual pens and divided into two treatments: chopped aruana grass (Panicum maximum cv. Aruana) hay (CON); aruana hay supplemented with chopped macrotiloma hay at a ratio of 75:25 grass to legume (MAC). Lambs were weighed fortnightly for calculation of average daily bodyweight gain (ADG) and CH4 emission was measured on three occasions (days 28 to 32; 57 to 61; 85 to 89) using the sulfur hexafluoride (SF6) tracer technique. At the last day of CH4 collection, rumen fluid samples were collected for: determination of ammoniacal nitrogen (NH3-N) and short chain fatty acids (SCFA); ruminal protozoa count; and relative abundance determination of general bacteria (BACT); Ruminococcus flavefaciens (RUMI); Fibrobacter succinogenes (FIBRO); methanogenic archaea (METH) by real-time quantitative PCR (real-time-qPCR) analysis. Subsequently, after 16 h fasting, the animals were slaughtered; carcass characteristics were then evaluated and longissimus thoracis samples were collected for fatty acid profile analysis. Key results No significant difference (P &gt; 0.05) was observed between MAC and CON for productive performance, CH4 emission, SCFA and carcass characteristics. Reduced protozoa count and relative abundance of METH were observed for MAC (P &lt; 0.05). Conclusions Despite the lack of effects on productive performance and CH4 emission, the decreased relative abundance of METH and protozoa count indicated that macrotiloma may possibly present anti-methanogenic activity. Implications The inclusion of this legume in the diet of ruminants may affect rumen microbes and potentially decrease environmental impacts of the production system.
