This study aimed to evaluate the effects of increasing the neutral detergent fibers (NDF) concentration of sugarcane-based diets on the growth and development of Holstein heifers. Twenty-seven Holstein heifers with a mean body weight of 265.5 ± 36.4 kg were housed in a sand bedded tie stall and fed individually. The experimental diet consisted of fresh sugarcane and concentrate. Three concentrations of sugarcane NDF were compared: 33% (SC33), 38% (SC38), and 42% (SC42). Crude protein content of experimental diets was 16%. The following parameters were evaluated: dry matter intake, weight gain and morphometric measures, digestibility, feeding behavior, and ruminal pH. The experimental design was a randomized block and all analyses were performed using the MIXED procedure in SAS. Intake of DM decreased as NDF concentration increased (p=0.07), but weight gain and growth were not significantly affected (p=0.74). As dietary NDF increased, chewing activity per unit DM intake increased (p=0.001), but rumen pH was not significantly affected (p=0.91). Diets formulated with 330?420 g of sugarcane NDF/kg of dry matter were sufficient to support the growth of Holstein heifers.

Abstract This study evaluated the effects of undigested neutral detergent fiber (uNDF) concentration and forage inclusion (FI) rate on dry matter (DM) intake, ruminal pH, reticular contractions, and gastrointestinal permeability for finishing beef cattle. Five ruminally cannulated Hereford′Simmental heifers (699±69.1 kg) were used in an incomplete 6×6 Latin square (26-d periods) with a 2×3 factorial treatment arrangement. Barley grain-based diets were formulated using barley silage or wheat straw to provide low or high uNDF (7.1 vs. 8.5% DM) with forage proportions of 5, 10, or 15% of dietary DM. Dry matter intake (P ≥ 0.10) and eating time (P ≥ 0.13) were not affected by uNDF, FI, or uNDF′FI. With low uNDF diets, increasing FI numerically (P = 0.02) increased rumination time (min/d); while, with high uNDF diets, rumination time increased with 5 to 10% FI, but not thereafter (P = 0.03). Mean ruminal pH was not affected by uNDF (6.17 vs. 6.19; P = 0.08), but increased with increasing FI (6.04b, 6.23a, and 6.28a; P = 0.02). Duration of ruminal pH < 5.5 was not affected by uNDF but tended (P = 0.07) to be reduced with increasing FI. High uNDF diet tended to increase the frequency of reticular contractions (1.43 vs. 1.51 contractions/min; P = 0.07) but decreased the contraction duration (13.2 vs. 14.1 sec; P = 0.04). Increasing FI increased contraction frequency (1.39b, 1.50a, and 1.53a contractions/min; P = 0.03) and tended to reduce contraction duration as forage increased from 5 to 10 and 15% (14.3, 13.1, and 13.6 sec; P = 0.07). Feeding high uNDF decreased (P = 0.05) permeability of the gastrointestinal tract based on the appearance of Cr-EDTA in urine following an intra-ruminal dose. Increasing FI tended to reduce gastrointestinal tract permeability (P = 0.06). Limited interactions indicate that uNDF and FI act independently suggesting that increasing dietary uNDF, without increasing FI rate, can stimulate frequency of reticulo-ruminal contractions and reduce gastrointestinal permeability for finishing cattle.

This study evaluated the use of babassu cake as a replacement for soybean meal and pineapple byproduct silage as roughage in the diets of feedlot sheep. Ten rumen-fistulated sheep were used and distributed in an experimental design consisting of two 5 x 5 Latin squares. Babassu cake replaced soybean meal at four concentration levels (0, 26.66, 53.33, and 80%), and pineapple byproduct silage was used as roughage. A treatment was also evaluated in which elephant grass silage was used as roughage and corn and soybean meal were used as the concentrate. No effect of babassu cake as a replacement for soybean meal on dry matter intake, neutral detergent fiber, or crude protein was observed. Higher babassu cake replacement levels in the diets resulted in linear reductions in the digestibility of the dry matter, neutral detergent fiber, organic matter, nonfiber carbohydrates and total carbohydrates. For the digestibility of the crude protein, no effect was observed after the addition of babassu cake. The replacement levels of the babassu cake had no effect on the intake and retention of the daily nitrogen, ammonia nitrogen and ruminal pH. Babassu cake could replace soybean meal at concentrations of up to 80% when the roughage source was pineapple byproduct silage. Compared with elephant grass silage, pineapple byproduct silage improves nutrient intake and digestibility and nitrogen intake, retention, and absorption without compromising the ruminal pH or ammonia nitrogen of feedlot sheep.

Twelve male growing lambs were used in a randomized complete block design to determine the effects of feeding liquid acid whey (LAW) on the performance of the animal, its dry matter intake, nutrient digestibility, weight gain and ruminal pH. Animals received a diet consisting of Napier grass (Pennisetum purpureum, Schumacher). Treatments were Napier grass plus concentrate, Napier grass plus LAW and Napier grass plus concentrate plus LAW. Individual dry matter intake (DMI), biweekly weight gain (WG) and ruminal pH were measured. Diet digestibility was determined using the total collection method. Results showed that LAW increased (p<0.05) WG and diet digestibility (dry matter, organic matter and crude protein). Liquid acid whey had an average digestibility of 54.41% for dry matter, 83.94% for organic matter and 87.56% for crude protein. Ruminal pH two hours after feeding was stable for animals with LAW alone. However, DMI was similar (p>0.05) among treatments. It can be concluded that including LAW in the diet significantly improved WG, diet digestibility and ruminal pH without affecting DMI.

A trial was carried out with four Holstein x Nellore crossbred steers (225±22kg of BW) fitted with ruminal and abomasal cannulaes in a 4 x 4 Latin Square design to evaluate the intake and the total and partial apparent digestibilities of nutrients, ruminal parameters, and microbial synthesis. Diets consisted of 60% silage and 40% concentrate formulated to be isonitrogenous (12.5% of crude protein, dry matter basis). Treatments consisted of different proportions of Brachiaria brizantha grass silage and sorghum silage: 100:0; 67:33; 33:67, and 0:100%, respectively, on dry matter basis. The intake of dry matter, organic matter, crude protein, ether extract, non-fiber carbohydrates, and total digestible nutrients linearly increased (P<0.01) as levels of sorghum silage increased. The total apparent digestibility of dry matter, organic matter, and neutral detergent fiber linearly increased with sorghum silage levels (P<0.02). The highest ruminal NH3-N (13.63mg/dL) levels occurred at 2.94h post-feeding whereas the lowest ruminal pH (5.87) was measured at 5.21h post-feeding. Microbial efficiency was not affected (P>0.05) by the treatments. The use of 67% of sorghum silage and 33% of grass silage increased intake and digestibility of nutrients without affecting ruminal pH, ruminal NH3-N, and microbial efficiency.

ABSTRACT The objective of this study was to evaluate the effect of the partial replacement of elephant grass silage with babassu (Orbignya speciosa) on the performance, intake, digestibility, and carcass weight gain of sheep. Fifty-four castrated male lambs (19.08±2.76kg) were distributed in a completely randomized design and administered one of the following treatments: 0.0, 12.5, 25.0, 37.5 or 50% dry matter (%DM) replacement of elephant grass silage with babassu cake. No difference (P> 0.05) was observed in the dry matter, crude protein, and neutral detergent fiber intake, but the ether extract intake increased (P< 0.05). The digestibility of the dry matter, neutral detergent fiber, and total digestible nutrients were unaffected. The crude protein digestibility decreased (P< 0.05), and the ether extract digestibility increased with the replacement of the elephant grass. There were no changes in mean daily weight gain and carcass weight gain. In the carcasses, a linear increase was observed in the proportion of the ether extract, and the crude protein decreased. The replacement of the silage with the babassu cake by up to 50% did not change the performance of sheep, however it led to an increase in fat deposit in the carcass.

ABSTRACTObjective. The objective of this study was to determine the effect on productiveperformance and carcass characteristics in lambs fed with different amounts of palmkernel cake. Material and methods. Thirty-two Santa Inês lambs, with an initial livebody weight of 24.8 ± 3.59 kg were used. Treatments consisted of four levels (0; 6.5;13.0 and 19.5%) of palm kernel cake added to the dry matter diet. Lambs were fed for80 days, and then slaughtered to be evaluated for the quantitative characteristics of thecarcass. Results. Intake of dry matter and non-structural carbohydrates decreased withincreasing levels of palm kernel cake. The intake of neutral detergent fiber showed a linearincrease. Crude protein and total digestive nutrient intake were not affected. Weight gain,and the feed:gain ratio of dry matter, organic matter, crude protein and total digestivenutrients were similar among the four treatments. There was an increase on the feed:gainratio of neutral detergent fiber and a decrease of nonstructural carbohydrates. The weightgain at slaughter and biometric measures were not affected by treatment. The carcasscompactness index showed a linear decrease. The indexes of leg muscularity, compactnessof the leg and rib eye area were similar among treatments. There was a linear decrease inthe cold carcass weight and commercial yield of the carcass. Conclusions. The diet madeof up to 19.5% palm kernel cake reduced DM intake, the carcass compactness index andcarcass commercial yield, but did not alter weight gain, or feed dry matter intake.

This study aimed to evaluate the effect of different non-fibrous carbohydrate (NFC):neutral detergent fiber (NDF) ratios (0.70:1, 0.90:1, 1.14:1, 1.42:1, and 1.85:1) in diets containing cactus cladodes on intake, digestibility, ruminal parameters, ingestive behavior, and microbial protein of growing heifers. Five rumen-cannulated heifers (194 ± 70 kg of body weight) were distributed in a Latin square design (5 x 5). There was a quadratic effect on the intake of dry matter (DM) (Kg day-1 and %BW) and crude protein (CP) with the increase in non-fibrous carbohydrate (NFC): neutral detergent fiber (NDF) ratio, with maximum values of 7.07 kg day-1, 2.86%, and 0.949 kg day-1, estimated for 1.37:1, 1.39:1, and 1.27:1 ratios. When the intake of NDF decreased, in turn, the intakes of NFC and TDN increased. The NDF digestibility decreased with increasing NFC levels in diets. The other nutrients were not influenced. The ruminal pH showed the lowest values at 4 hours after feeding, mainly for animals fed the 1.85:1 ratio. There was a quadratic effect for rumination time with maximum values estimated for an NFC:NDF ratio of 0.88:1. The time spent idle increased linearly, while total chewing time and feeding efficiency of NDF decreased. The urinary volume increased linearly. However, microbial protein synthesis and the efficiency of the synthesis were not influenced. The number of protozoa increased by 64.5% with the elevation of the NFC:NDF ratio. We recommend a NFC:NDF ratio of 1.37:1 in diets containing cactus cladodes, to improve the use of nutrients, without negatively affecting ruminal parameters.

The objective of this study was to evaluate the performance and digestibility of diets containing different levels of crude propolis for growing rabbits. Forty-eight New Zealand White rabbits, 43 days old, of both genders, were used, distributed in a completely randomized design. There were four diets with different inclusion levels of crude propolis (0.0; 0.5; 1.0 and 1.5%). There was no statistical difference for performance regarding the inclusion levels of crude propolis (p = 0.85), as well as for the variables dry matter consumption, neutral detergent fiber and acid detergent fiber (p ≥ 0.07). Crude protein consumption showed a statistical difference in relation to gender (p = 0.04): males showed higher consumption. However, final weight, total weight gain, daily weight gain and feed efficiency were not influenced by the addition of crude propolis (p ≥ 0.37). Dry matter digestibility, crude protein, neutral detergent fiber and acid detergent fiber were not influenced by the inclusion levels of crude propolis in the diets (p ≥ 0.12). This study indicates that the inclusion of raw propolis up to 1.5% in the diets does not affect the performance parameters of rabbits.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.
