Abstract This study addressed the different proportions of millet and sorghum silage biomass BRS 716 (BRS-716 silage) in the diet of crossbred heifers ½ to ¾ Holstein x Zebu on their nutrient intake, and digestibility, microbial protein synthesis, nitrogen balance, ingestive behavior, and growth performance. Five experimental diets with 0, 25/75, 50/50, 75/25, and 100% of BRS-716 silage in compared to millet silage were evaluated. The roughage: concentrate ratio in the total dry matter (DM) of the diets was 75:25. The diets were evaluated in ten heifers with an initial body weight of 264.95 ± 19.4 kg (± SEM), following the experimental design in two 5 x 5 Latin squares, simultaneously. The increase in the proportion of BRS-716 silage in the diet of crossbred dairy heifers did not change the dry matter intake (DMI), total digestible nutrients, indigestible neutral detergent fiber (iNDFI), and metabolizable energy. The means observed for DMI, and iNDFI were 7.85 kg/day, and 1.18 kg/day, respectively. For the excretion of purine derivatives, and microbial synthesis, there was no significant effect (P > 0.05), the mean microbial crude protein synthesis was 503.37 g/day. The different proportions of the BRS-716 silage, and millet silage did not change the final body weight (P = 0.89), weight gain (P = 0.08), feed efficiency (P = 0.50), and the body measurements of heifers (P > 0.05). The final body weight and average daily gain of heifers were 278.46 kg, and 0.795 kg/day, respectively. The millet silage, and BRS-716 silage in the diet of crossbred Holstein x Zebu heifers, used exclusively or combined in different proportions, allow dry matter intake, and nutrients, digestibility, nitrogen balance, microbial crude protein synthesis, ingestive behavior, and performance similar body.

SUMMARY It was evaluated the effect of feed supplementation at 0.4; 0.8 and 1.2% of body weight (BW) on intake and digestibility of crossbred goats finished on caatinga, in relation to crossbred goats not supplemented (0.0% of BW). Thirty-two crossbred, Anglo-Nubian goats were used, eight months old and with body weight of 18 ± 2.5 kg, organised into randomised blocks, which were kept on 37 hectares of caatinga from 7 h to 16 h. Intake of dry matter, organic matter, crude protein, ether extract, neutral and acid detergent fibre, total carbohydrates and total digestible nutrients was influenced (P<0.05) by the levels of feed supplementation, with linear increases of 202.31; 179.42; 25.05; 11.83; 35.79; 12.27; 142.63 and 166.79 g animal-1 day-1 respectively. There was a substitution effect (P<0.05) on dry matter intake when using feed supplementation at 0.7% BW. Feed supplementation resulted in positive linear effect (P<0.05) for digestibility of dry matter, organic matter, crude protein, ether extract, total carbohydrates, total digestible-nutrient content and digestible energy, with an increase of 17.15; 16.64; 19.07; 44.74; 15.15 and 17.56% for dry matter, and 0.69 Mcal kg-1 of dry matter respectively. Final body weight, total gain and average daily gain, showed a linear increase (P<.005) of 2.60, 3.09 and 0.036 kg per percentage point of each additional level of supplement. Feed supplementation increases the intake and digestibility of total dry matter and nutrients, a fact that makes greater performance possible, and recommends use up to a level of 0.7% BW to avoid any substitution effect.

Abstract. This study was aimed to examine the excretion of urinary creatinine in young and mature Kacang goat bucks under different feeding levels. This study used 16 Kacang goat bucks consisting of 2 groups of age, i.e. eight young bucks (aged 6-7 months, weighed 12.75±2.68 kg) and 8 mature bucks (age 9-12 months, weighed 17.34±3.32 kg). The bucks were fed pelleted complete feed containing 78.82% dry matter (DM), 18.80% crude protein (CP), and 76.29% total digestible nutrients (TDN). The bucks were allocated into a 2x2 nested design with four replications. The treatment was the amount of  2.24% dry matter intake  (T1) and 4.48% of body weight (BW) (T2) for the young goat, while the mature buck was 1.87% and 3.74%, respectively. The results showed that DM, CP and TDN intake were significant different across ages and highly significantly different between feeding levels. Changes of urinary creatinine from week 0–12 showed no differences in the age group (142 mg/dl) and feeding level (143 mg/dl). Conclusively, age and feed level affected body weight, feed intake and creatinine excretion of Kacang Goat.  The more body weight gain (age) and feed level, the more urinal creatinine excretion in male Kacang goat. Key words: Kacang goat, ages, feeding level, and creatinine Abstrak. Penelitian ini bertujuan untuk mengkaji kadar kreatinin pada kambing Kacang muda dan dewasa dengan jumlah pemberian pakan yang berbeda. Materi berupa 16 ekor kambing Kacang jantan, terdiri dari 8 ekor umur muda (6-7 bulan) dan 8 ekor umur dewasa (9-12 bulan). Pakan komplit yang diberikan memiliki kandungan bahan kering (BK) 78,82%, protein kasar (PK) 18,80%, dan total digestible nutrients (TDN) 76,29%. Rancangan penelitian ini adalah pola tersarang 2x2 dengan 4 ulangan.

Abstract The objective of this study was to evaluate the growth performance and carcass traits of finishing bulls fed diets containing, on dietary dry matter basis, different levels of corn wet distillers bran plus solubles (WDBS; 0, 15, 30 or 45%) added with or without corn oil (CO; 0 and 3%). A total of 205 Nellore bulls (390 ± 25 kg initial BW) were blocked by initial body weight, distributed in 40 pens and pens within weight block were randomly assigned to treatments in a 2 × 4 factorial arrangement. Diets were isonitrogenous and contained 8.5% sugarcane bagasse and 91.5% concentrate (ground corn, soybean meal, pelleted citrus pulp, urea, mineral). The WDBS (FlexyDDG®) and the corn oil were from SJC Bioenergia (Quirinópolis, Goiás, Brazil). Data were analyzed using the PROC MIXED procedure of SAS. An interaction between CO × WDBS levels was observed for dry matter intake (DMI; P = 0.032). In diets without CO, increasing levels of WDBS linearly (P = 0.004) reduced the DMI, but in diets containing 3% CO, increasing levels of WDBS quadraticaly affected the DMI (P = 0.002). No effects of CO, WDBSF levels or CO × WDBS levels were observed for final body weight, average daily gain, hot carcass weight and dressing percentage. Feed efficiency tended (P = 0.07) to be greater for bulls fed diets containing CO (0.154 vs. 0.144). Increasing levels of WDBS tended (P = 0.09) to increase the feed efficiency. In summary, increasing levels of WDBS in finishing diets linearly (in diets without CO) or quadratically (in diets with CO) reduces the dry matter intake. Adding CO and WDBS tend to increase feed efficiency.

Four concentrations (0, 200, 400, 600 and 800 mg extract per ml of water) of mesquite extract were used as phytogenic additive to verify the potential to increase the nutritional value of the feed, ruminal parameters (primarily propionate production) and nitrogen use efficiency, microbial protein synthesis and quantify the reduction of ciliated protozoa and characterize the ingestive behavior of sheep. Ten adult male sheep were subjected to a 5 × 5 double Latin square design. Prior to feeding, the animals received the mesquite extract. Nutrient intake was estimated from the difference of the amount of feed provided and the total surplus. Rumen content samples were collected to evaluate the profile of short-chain fatty acids, ammonia nitrogen, pH, ciliated protozoa, turnover rate and disappearance rate. To estimate the microbial protein synthesis, the technique of purine derivatives was used. The mesquite extract quadratically increased (P < 0.05) the digestibility of dry matter, organic matter, crude protein and total digestible nutrients, as well as increased propionate production, acetate:propionate ratio and microbial protein synthesis. The numbers of ciliate protozoa in the rumen decreased as a result of mesquite extract inclusion in the diet. The use of mesquite pod extract at a concentration of 488 mg/mL is recommended to improve digestibility of dry matter, organic matter, crude protein and total digestible nutrients, and to optimize microbial protein synthesis and increase propionic acid production.

The objective of this work was to investigate the ingestive behavior of sheep fed with different inclusions of babassu endocarp meal I. The animals receive isofibrous, isoenergetic and isonitrogenous diets containing the by-product in increasing levels of inclusion (zero; 7,5%; 15%; 22,5%). Twenty rams were used in this study and distributed in four treatments with five repetitions each. The ingestive behavior was conducted over a period of 24 hours, with visual observations at 5 minutes intervals and the variables being: idle, ruminating, feeding and chewing. The study demonstrated that the dry matter intake in function of the body weight and the metabolic weight decreased linearly as the babassu endocarp meal I was included in the diet. The feeding, ruminating and chewing efficiency when expressed in grams/dry matter/hour was reduced in a linear response with the different inclusions of the by-product. The ingestive behavior of feeding, idle, rumination and chewing activities in minutes/day was not altered in this study

This study was designed to investigate the effects of supplementation of high and low energy based concentrate diets (13.77 Vs 12.14 MJ/kg DM metabolizable energy) on the nutrient intake and body weight changes of indigenous growing buffalo bull calves in Bangladesh. The crude protein contents of both the supplemented diets were similar (about 12.50% on DM basis). In this study, a total of fifteen indigenous growing buffalo bull calves (av. Live weight 85.10±0.874 kg) were selected from different villages. It was found that the total dry matter intake was the highest (28.22±0.015 g/kg W0.75/d) in group supplemented with high energy concentrate diet along with farmer’s practices (D1), thereafter, in group supplemented with low energy concentrate diet along with farmer’s practices (D2) (27.79±0.015 g/kg W0.75/d) and the lowest (26.39±0.016 g/kg W0.75/d) in control group (D0) in which the animals were fed only farmers practices diet. Similarly, the crude protein intake was the highest in D1 group (2.86 ±0.029 g/kg W0.75/d), followed by D2 group (2.83±0.010 g/kg W0.75/d) and the lowest in farmer’s practices diet, D0 (2.08b±0.021 g/kg W0.75/d).  However, the final body weight of buffalo bull calves was higher in both groups supplemented with concentrate diets (D1 and D2) compared with control (D0) and differed significantly (p<0.01) while there were no significant differences (p>0.05) found between D1 and D2 where high energy concentrate supplementation group buffalo bull claves, D1 tended to be higher than low energy concentrate supplementation group buffalo bull claves, D2. The highest final (254.6 kg) body weight was recorded in high energy concentrate supplemented diets and the lowest (144.0 kg) was found in control. Additionally, the average final body weight was increased by 153.40 kg (151.58%), 150.40 kg (152.22%) and 45.60 kg (46.34%) in D1, D2 and D0 group buffalo bull calves, respectively. On the other hand, the average final body weight of D1 and D2 was increased by 110.60 kg (76.80%) and 105.20 kg (73.05%), respectively, compared with D0. In addition, the highest (6.46) feed conversion efficiency (FCE) was recorded in D1 followed by D2 (6.64) and the lowest (12.17) was found in D0. The trends of cost benefit ratio was the same like other considering factors, the highest (1:3.60) found in D1 followed by D2 (1:3.51) and the lowest (1:1.97) in D0. Finally, considering all the parameters, it was clearly indicated that supplementation of concentrate diet along with farmers practice is essential for fast growing, higher body weight gain and more benefits by rearing buffalo bull calves at Subornochar Upozila of Noakhali district in Bangladesh.

AbstractOur objective was to estimate nutrient intake, ruminal flow, total apparent and ruminal digestibility, rates of passage and digestion, ruminal and omasal pH, blood metabolite concentrations, and body measurements during gestation of Holstein heifers. Eleven pregnant Holstein heifers, 8 of which fitted with a rumen cannula (450 ± 27.6 kg of body weight and 20 ± 3.5 months of initial age) were used. All heifers received the same diet composed of corn silage, soybean meal, corn meal, minerals and vitamins, with a corn silage:concentrate ratio of 50:50 (on a dry matter basis), aiming an average daily gain of approximately 1.0 kg. The sampling periods were established according to the days of gestation: 145, 200, and 255 with a duration of 10 days per period. Total fecal samples were collected to estimate dry matter, organic matter, crude protein, and neutral detergent fiber digestibility. Blood samples were collected to analyze metabolites (non-esterified fatty acids, β-hydroxybutyrate, urea, and glucose). Data were analyzed as a repeated measurements scheme, using MIXED procedure, with differences declared when P < 0.05. Dry matter intake expressed in kg/day increased from d-145 to d-200, and remaining stable until d-255 of gestation. The same results were observed for organic matter and crude protein intake, increasing 15.0 and 35.8% respectively. In contrast, when dry matter intake was evaluated as % body weight, we observed a decrease of 16.7% from d-200 to d-255. Days of gestation did not influence ruminal flow of dry matter, organic matter, crude protein, and neutral detergent fiber. We observed an increase in the ruminal digestibility of neutral detergent fiber by 20.5%. The apparent total-tract digestibility of dry matter, organic matter, and crude protein changed over days of gestation, with an increase of 11.9, 8.5, and 9.8%, respectively, when comparing d-145 with d-200. The rate of digestion of neutral detergent fiber increased from 2.0 to 3.5% h-1. Glucose levels decreased, while β-hydroxybutirate and non-esterified fatty acids increased from d-145 to d-255. In conclusion, our results demonstrate a reduction in dry matter intake in % body weight due to pregnancy. It also shows an increase in total apparent digestibility through gestation, which imply a greater efficiency of use of nutrients by pregnant animals. Thus, further research is still needed to consolidate such results and to elucidate the mechanism about nutrient usage during the final third of gestation in heifers.

ABSTRACT Here in this study we assessed dairy heifers kept in tropical grasslands during spring and summer seasons to observe the effects of two supplementation strategies upon their performance. Sixteen dairy heifers (Holstein 5/8 x Gyr 3/4) with 135.25 kg of body mass were randomly assigned in two supplementation treatments (e.g., mineral salt and protein salt supplement) during spring and summer seasons, divided into two groups of eight animals that represented 4.29 animal unit ha. Initial and final fasted weights (i.e., feed and water withheld for 16h) were obtained before to start and at the end of each grazing cycle (28 days), and then the weight gain (kg animal-1) per grazing cycle was calculated by the difference between final and initial weights. There was no significant effect (P <0.05) on the intake of dry matter, crude protein, ether extract, neutral detergent fiber, and dry matter digestibility, between treatments (P <0.05). However, there was a significant effect (P <0.05) between seasons; e.g., respective means of dry matter intake (kg day-1,% BW g / kg 0.75), intake of crude protein (g day-1 g / kg 0.75), ether extract (g day-1), neutral detergent fiber (g day-1 and% BW) were 3.95 and 2.88 kg, 2.54 and 1.65%, 89.27 and 59.56 g kg0.75, 429.89 and 298.43 g day-1, 9.72 and 6.18 g kg0.75, 118.79 and 84.07 g day-1, 2.90 and 2.05 kg day-1, 1.86 and 1.18%, for Spring and Summer seasons. Moreover, the dry matter intake (% BW and g kg 0.75 of DM) were higher (P < 0.05) during the spring season (e.g., 2.53 vs 1.64 % BW; and 89.26 vs 59.56 g kg0.75 DM).

<p>This study aimed to evaluate nutrient intake and digestibility by sheep fed diets containing residue from the extraction of tamarind pulp (RETP). We used four sheep with a mean body weight (BW) of 40.38 kg, whose pens were distributed in a Latin square design. The diet treatments contained 0, 5, 10 and 15% of RETP. The variables were subjected to analysis of variance and the differences observed were tested using regression equations at 5% significance. The intake of dry matter (DM), organic matter (OM), crude protein (CP), total carbohydrates (TC), and non-fiber carbohydrates (NFC),expressed in g day-1, % BW and g kg0,75-1, were not significantly affected (p&gt;0.05) by the inclusion of RETP. The intake of ether extract (EE) and neutral detergent fiber (NDF) showed a linear increase (p&lt;0.05) as RETP content rose. However, the digestibility of DM, CP, TC, and total digestible nutrients (TDN) decreased linearly (p&lt;0.05), while the digestibility of EE, NDF, ADF, and NFC, with average values of 62.12%; 79.95%; 41.59%; 37.12%, and 91.57%, respectively, were not significantly affected (p&gt;0.05) when RETP was included in the diet. The inclusion of up to 15% of the residue from the extraction of tamarind pulp changes the intake of ether extract and neutral detergent fiber, and reduced dry matter, crude protein, and total carbohydrates in the sheep’s diet.</p>

This study was aimed to examine the effect of dietary crude protein (CP) concentration on carcass and meat production in young and adult Kejobong goats. This study used 8 young (5 months) and 8 adult (9 months) Kejobong goats; which were allocated to a randomized nested design, with an age of goat as the nest, and treatment applied was dietary protein concentration (T1: 9.96%; T2: 14.66%). The parameters observed were dry matter intake (DMI), CP intake (CPI), body weight gain (BWG), and the production of carcass meat. The results showed that the DMI of adult goats (910 g/d) was higher (P<0.05) than that of young goats (680 g/d). The goats fed diet T2 had higher (P<0.05) DMI, CPI, and BWG (855 g, 140 g, and 94 g/d, respectively) than those of T1 (725 g/d, 80 g/d, and 59 g/d). Slaughter weight, carcass weight and carcass meat weight, and carcass meat percentage of adult goats (28.09 kg, 13.19 kg, 8.60 kg and 64.94%, respectively) were higher (P <0.05) than those of young goats (20.06 kg, 8.72 kg, 5.46 kg, and 62.06%, respectively). The weight and percentage of carcass meat of T2 (8.30 kg and 64.99%, respectively) were higher (P<0.05) than those of T1 (5.75 kg and 62.06%, respectively). The meat-bone ratio of adult goats was higher (P<0.05) than that of young goats (3.53 vs 2.85). The meat-bone ratio of T2 (3.58) was higher (P<0.05) than that of T1 (2.80). It was concluded that adult Kejobong goats produced more meat than the young ones, and the goat-fed diet with 14.66% CP produced more meat than that with 9.96% CP.
