The objective of this study was to evaluate the use of sorghum silage, Buffel grass hay and forage palm fodder in the diet of dairy goats by means of performance tests and economic viability of different roughage sources. Eight Anglo-Nubian goats, multiparous, weighing around 40.13 ± 2.76 kg of live weight were used. The experiment lasted 84 days, consisting of four periods of 21 days, distributed in two Latin squares (4x4). The treatments represented by diets with different volumetric sources: SSCF: (sorghum silage+ forage palm+ concentrate); BHCF: (Buffel grass hay + cactus forage+ concentrate); SS: (sorghum silage+ concentrate) and BH: (Buffel grass hay + concentrate). Nutritional intake, digestibility, feed behavior, milk production and chemical composition and economic analysis were evaluated. Animals fed the BHCF diet had higher nutrient intakes and consequently were more productive in fat, protein, lactose, fat free solids and total solids. The BHCF diet led to a higher gross income in Brazilian currency. The safety margin of the SSCF diet presented the highest percentage, with 43.06%, and the BHCF diet, the lowest percentage, of 14.89. The association of forage palm with sorghum silage and Buffel grass hay can be used as a bulky source in lactating goat diets.

Concentrated feed can be used to increase the milk yield in dairy farms. However, the feeding cost increases when concentrates are used and, sometimes, farmers lose competitiveness, if the cows do not produce what is expected with supplementation. Thus, this study aimed at evaluating the nutrients intake, milk yield and composition and live weight change of dairy cows fed with sorghum silage alone or supplemented with concentrates. Nine crossbred cows (Holstein-Gyr) were allocated in three balanced Latin squares and fed with sorghum silage supplemented with minerals (0.2 kg) or with 2.6 kg (38.5% of crude protein) or 5.0 kg (20% of crude protein) of concentrate per day, aiming at supplying the same amount of crude protein (1.0 kg day-1). The dry matter intake and milk yield were higher for the cows fed with concentrate, independently of its protein level. The productive response (in kg of milk per kg of concentrate) was 1.67 and 0.83, respectively for the low and high supplemental levels. The cows that received only minerals lost weight, while those fed with concentrate gained weight. The cows which produced 13.0 kg of milk day-1 showed a higher increase in milk yield when fed with supplements containing high protein and mineral contents. The response for milk production per kg of concentrate was higher when lower amounts of concentrate with high protein and mineral levels were used, allowing a reduction in the production costs.

Recent genetic improvement has developed pigs with maximum potential for protein deposit at higher weights; however, their optimal slaughter weight still needs to be determined. The objective of the study was to evaluate live performance, carcass traits, and economic viability of 417 Agroceres PIC pigs slaughtered with 100, 115, 130, and 145kg live weight. Pigs were reared in pens with 10-11 barrows and gilts each, offered a feed allowance of 2.8kg/pig/day until the following slaughter weights (SW): 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, and 143.90±1.24. There was no interaction between sex and SW (P>0.05). Backfat thickness, fat area, and loin eye area linearly increased with SW (P<0.001; R2: 70.12-77.44%), and carcass yield increased in a quadratic manner (P<0.001; R²=24.66%). Lean yield was not affected (P>0.05), and feed conversion ratio (R²=43.29%) linearly worsened with SW (P<0.001), but the effect of SW on live production cost (R$/kg) was quadratic, with the minimum point at 134.8kg. It was concluded that, under the applied management, increasing SW results in larger amount of lean tissue with no change in its yield and little effect on growth performance.

<p>This study aimed to evaluate the correlations of intake, digestibility and performance with the ingestive behavior of lambs fed diets containing ammoniated buffel grass hay. Buffel grass hay was treated with four levels of urea (0, 18, 36 and 54 g/kg DM basis) and eight repetitions. Thirty-two sheep with no defined breed and an average body weight of 17.7 ± 1.8 kg were distributed in a completely randomized design. It was observed positive correlations were found between the feeding time and the intake of dry matter (r = 0.3120), organic matter (r = 0.3242), neutral detergent fiber (r = 0.3800), total carbohydrates (r = 0.3343) and total digestible nutrients (r = 0.3233). Positive correlations (P &lt; 0.05) were found among the rumination efficiencies, g of DM/h and g of NDF/h with nutrient intake variables, except for ether extract intake. Positive correlations were observed (P &lt; 0.05) between both total weight gain (TWG) and average daily gain (ADG) and the rumination efficiency, g of DM/h (r = 0.3330) and g of NDF/h (r = 0.3304). The feeding and rumination efficiencies have a positive relationship with the total digestible nutrients. The correlation among intake, digestibility and performance variables with the ingestive behavior, it was important for the understanding of diet containing ammoniated buffel grass hay, in which the positive correlation of rumination efficiency with intake and weight gain explained the favorable effect on productive performance of feedlot sheep.</p><p><strong> </strong></p>

This study aimed to evaluate the effects of the inclusion of different levels of sun-dried banana peel in the diet for crossbred cows on the quality of Minas fresh cheese and milk. Diets consisted of 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel. Ten cows were assigned to two 5 x 5 Latin squares experimental design. Milk samples were taken from each cow and analyzed for composition. Milk was pasteurized for the production of Minas fresh cheese, which was weighed to determine the yield and analyzed for texture, physical and chemical characteristics and consumer acceptance test. Milk urea nitrogen had a quadratic effect with minimum point at 43.76% replacement of silage with banana peel. The remaining items evaluated in the composition of milk and cheese and the consumer acceptance test were not influenced by diets with banana peel. The replacement of up to 60% sorghum silage with banana peel is a viable alternative because it causes no alteration in physical and chemical composition of milk and Minas fresh cheese, as well as consumer acceptance.

Live Yeast

Any method to increase the utilisation of nutrients from feeds given to horses exercised on a regular basis is important. Commercially-available dried yeast cultures, used as supplements to equine diets have been shown to increase the digestibility of gross energy and enhance the retention of N in yearling horses (Glade and Biesik, 1986). There is however, limited information on whether the increase in digestibility of GE or enhancement in retention of N occurs in mature horses (Glade and Campbell-Taylor, 1990). The aim of the research reported here was to determine the effect of a dried live yeast culture on the digestibility of nutrients from a mixed diet given to riding school horses.Six 2 and 3 year old riding school horses (mean live-weight 433 (s.e. 11.1) kg) were allocated to three balanced 2 x 2 Latin squares with two treatments and two periods of 3 weeks. The first 14 days of each period was a preliminary and the last 7 days was for measurement. The horses were housed individually (bedded on saw dust) and given 13.5 kg DM hay and 3.0 kg DM concentrate mix as a base diet. The base diet was either supplemented with 10 g dried yeast culture (S) or not supplemented (N).

The objective of this study was to evaluate the use of multinutritional blocks (BMs) associated with the concentrate content in the diet of lactating goats and their effects on milk production and economic viability. Eight goats Parda Alpina, multiparas were distributed in two Latin squares (4x4). The experiment consisted of four treatments (0.971, 0.746, 0.521 and 0.296 kg concentrate day-1 per goat) and BMs ad libitum. It was evaluated the consumption, milk monitoring and the system was analyzed economically. If there was a significant effect of the concentrate, the control treatment was compared to the others using the Dunnett test and 5% regression analysis. When the concentrate contents were high in the diets, the total dry matter intake decreased linearly. However, there was an inverse behavior for the consumption of BMs. Milk production (PL kg day-1) was linear and positively related to the increase of concentrate levels in the diets. The PL was lower for the decreasing levels of concentrate when compared to the control diet. The economic parameters indicate that the use of low concentrate levels associated with BMs is the best feeding strategy for lactating goats. The multinutritional blocks can be used to feed lactating goats to partially replace the concentrate.

This study aimed to evaluate the inclusion of palm kernel cake in the diet for lactating crossbred cows in feedlot system, and its implications on economic viability. We used 12 crossbred Holstein x Zebu cows assigned to three 4 x 4 Latin Squares, in the following treatments: control (without inclusion of palm kernel cake in the diet); inclusion of 50, 100 or 150 g palm kernel cake (PKC) per kg in the total dry matter (TDM). Earnings per animal showed a reduction in values, this decrease in profitability is related to the increase in feed costs, specifically, and the costs with concentrate, which increased as the palm kernel cake was included in the treatments, 0, 50, 100 and 150 g kg-1 TDM. The effect observed for profitability affected the internal rate of return, which decreased with the inclusion of palm kernel cake levels in the diet. However, it was positive in all treatments, demonstrating the feasibility of investment in palm kernel cake. Data on the economic viability evidenced that treatment with 100 g palm kernel cake per kg TDM is the most financially viable under the conditions of this study.
