“…This fact is reflected both in the animal metabolism as well as in production costs. According to Rogério et al (2013), the diet that was formulated for sheep by the National Research Council (NRC) (2007), with 60% rumenundegradable protein (RUP), is the most appropriate alternative when considering the variable production costs.…”

Effects of diets with high and low protein contents and two concentrate levels in Santa Ines×Texel lambs

et al. 2015

a b s t r a c tTwo experiments were conducted to evaluate the effects of diets containing two levels of crude protein (CP) and concentrates on the intake, total nutrient digestibility, nitrogen balance (NB), microbial efficiency, and performance of lambs. The diets consisted of 10% or 14.25% CP and 40% or 60% concentrate, with corn silage as the forage. In the digestibility assay, four intact male F1 Santa Ines Â Texel lambs, with an average body weight of 21.0 7 2.48 kg and rumen-cannulated, were used. The lambs were distributed in a 4 Â 4 Latin square design with four treatments and four periods. There was no effect of the CP Â concentrate interaction on the variables that were studied. There was an effect of CP levels on the intake and digestibility of CP, as well as on the amounts of N that were ingested, absorbed, and retained from urine (NB). There was also an effect of CP levels on uric acid excretion. In the performance assay, 32 intact F1 Santa Ines Â Texel lambs with an average body weight of 19.0 7 2.02 kg were used. They were distributed in a 2 Â 2 factorial arrangement of treatments in a randomized block design with eight replicates. There was a significant interaction between CP and concentrate levels on the ether extract (EE) intake. The CP level affected the intake of dry matter (DM), organic matter (OM), CP, neutral detergent fiber corrected for ash and protein (apNDF), non-fiber carbohydrates (NFC), total digestible nutrients (TDN), and rumen-degraded protein (RDP), as well as the carcass gain (CG) and the feed conversion (FC). Concentrate levels affected the intake of DM, OM, CP, NFC, TDN, and RDP, as well as the CG, the CG/average daily gain (ADG), and the FC. It was concluded that levels of CP and concentrate do not affect microbial efficiency or nutrient digestibility, except for CP digestibility. A high level of CP or concentrate in the diet results in greater nutrient intake and better animal performance.

The objective of this study was to evaluate the economic and financial viability of replacing corn with biscuit bran (BB) in diets for Morada Nova lambs in feedlot. Twenty lambs confined with initial body weight of 17.00 ± 3.74 kg were used, arranged in four treatments, diet without biscuit bran (BB) and diets containing 15, 30 or 45% of biscuit bran in place of corn in the diet. Data, expenses and revenues of the activity were obtained during the period of January 2020 in the municipality of Sobral, Ceará. The economic and financial evaluation was carried out descriptively, using Excel® spreadsheets. In the scenarios evaluated, feeding, animal acquisition and labor costs were the items that most contributed to production costs. The highest food costs were observed in the system that used 15% of BB, representing about 32.86% of the total costs. The simulation for sheep production provided revenue higher than the production costs in all diets tested, resulting in positive economic indicators. On the other hand, although the system that uses diet without biscuit bran provides positive revenue, net income was the lowest (R$ 12,117.15 year-1). It was observed that all scenarios had a leveling point higher than 5,000 kg of meat year-1. The total productivity of the factors of all treatments evaluated was higher than 1, which indicates that the activity is stable, presenting high internal rates of return. Similarly, profitability rates are attractive, especially for diets containing BB, where the net present value is higher (R$ 362,143.26). Sensitivity analyses showed that even in the most unfavorable situations, such as a 30% reduction in production and market price, indicators are economically viable. The use of BB does not compromise the economic viability of the diet compared to the diet without BB, they present higher profitability, especially at the level of 15% in the diet.
