Abstract:
The objective of this work was to compare the tissue composition of the main
special cuts of sheep supplemented with multinutrient blocks (MBs) with and without
purging potato meal (O. macrocarpa) in its composition and analyze the financial and
economic viability these special courts. The research was conducted at the Center for
Research and Education Semi-Arid (NUPEÁRIDO) of the Federal University of
Campina Grande (UFCG) in the meat processing sector Mocó Agricultural Ltda. the
Tamanduá Farm, Santa Terezinha-PB. MBs were produced by the State Enterprise for
Agricultural Research of Paraíba SA (EMEPA-PB). We used 24 sheep type Santa Ines,
males, with an average age of 6 months, average weight of 26.5 kg. The animals were
divided into 4 treatments: Treatment 1 (T1) received only MBs (positive control);
Treatment 2 (T2) were added with MBs purge potato meal at a dose of 1 g / kg / bw; in
treatment 3 (T3) blocks added with the same meal at 0.5 g / kg / bw, 50% of the dose of
T2; and Treatment 4 (T4) and MBs separately by a chemical anthelmintic
subcutaneously (Moxidectin 1%) in a single dose of 1 mL / 50 kg (negative control). At
the end of the experimental period, the animals were slaughtered. From left carcass
were conducted in nine special courts: Sliced neck, shoulder, loin discovered, covered
loin, rib, sirloin, filet mignon, steak and leg. These were dissected and their constituent
tissues were separated and weighed. The cost structure and revenue used in the
economic analysis was the Effective Operating Cost, Total Operating Cost, Fixed Cost,
Variable Cost, Total Cost of Production, Gross Revenues and Gross Margin.
Depreciation was calculated using the straight line method. The cash flow was formed
by values of the entry and exit of resources and products per unit of time that make up
the investment proposal. Was considered the time horizon of 10 years. We considered
three indicators of economic viability: Net Present Value, Internal Rate of Return and
the simple payback. The Return Attractiveness Minimum Rate was the profitability of savings accounts (6%). There were no differences in the consumption of MBs between
treatments. In relation to tissue constituents of special cuts, there was a significant
difference (P <0.05) in total income of muscle and muscle relationship / cut bone "leg"
of T2. In carré cut cover of T2 dorsi muscle Longuissimus was heavier. Cutting
"palette" was no difference in intermuscular fat T4 and T2. In cut prime rib was
subcutaneous fat T4 that was superior to the others. The rest of the special courts did not
differ from their constituents between treatments. The average cost of production of
kilogram live weight was R $ 5.23 per animal slaughtered and R $ 136.58. The gross
and net margins were positive. Earnings and profitability had incipient results. The Net
Present Value (NPV) was negative and the Internal Rate of Return (IRR) was higher in
the live animal sales model. However, in both cases, there is inability return on
investment (payback) over the next ten years. It can be concluded that the use of
compounds of MBs purge potato meal as a nutritional supplement provides gains in
ovine muscle and fat composition of special cuts carcass when consumed in an amount
permitting intake of 1g / kg / PV . As regards the economic analysis, one can conclude
that it is not feasible to implement special cuts of the carcass of lambs within the
Paraíba, in view of the low values of financial indicators that point to a capital return
inability invested over ten, making it unaffordable model economically.
