The effects of supplementing low (23.9%) dry matter (DM) and medium (28.9%) DM corn silage roughage rations fed ad libitum to high-producing dairy cows, with orchard grass hay at 0.7% of their body weight on milk production and composition, was determined in a double reversal feeding trial using 24 lactating cows. Cows fed medium DM corn silage consumed 15.2% more DM/100 kg body weight daily than those cows fed low DM silage (P < 0.05). Supplemental hay fed with either low or medium DM silage resulted in equal consumption of total forage DM/100 kg body weight by cows on the two treatments. Each kilogram of hay DM consumed by cows offered low DM corn silage reduced silage DM intake by 0.47 kg, whereas hay DM intake reduced silage DM intake by 0.79 kg for cows offered medium DM silage. Daily production of 4% fat-corrected milk (FCM), percent nonfat solids (SNF), and daily body weight gain were lower for cows consuming low DM corn silage than for those on the other treatments (P < 0.05). Cows consuming low DM corn silage plus orchard grass hay at 0.7% of their body weight produced milk at the same level and of similar protein, lactose, and SNF content as those fed medium DM silage plus hay. Supplemental hay fed with medium or low DM corn silage increased FCM production over feeding silage alone, independent of DM or moisture content of the silage fed (P < 0.05).

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.

Corn Silage

In two experiments, lactating cows (26 in exp. 1; 32 in exp. 2) were fed an 11.3% crude protein (CP) diet, a 14.7% CP diet containing untreated soybean meal (SBM) or a 14.6% CP diet containing formaldehyde-treated SBM (FSBM), all three fed as a complete blended diet with control corn silage (CCS) (exp. 1); a 12% CP diet, a 13.4% CP diet containing SBM or a 13.3% CP diet containing FSBM, all fed as a complete blended diet with urea-treated corn silage (UCS) (exp. 2). In both experiments concentrates and CCS or UCS were mixed (50:50 dry matter) daily and fed ad lib for a 16-wk period. The increase of CP over the low CP negative control by addition of untreated SBM resulted in a significant (P < 0.05) increase in milk production in both experiments. The addition of FSBM had no significant effect. When comparing solids-corrected milk (SCM), addition of SBM, whether treated or not, significantly increased SCM in both experiments. In neither experiment did FSBM improve milk production over untreated SBM. All animals fed CCS lost body weight but there was no difference between treatments. For animals fed UCS the low CP group lost significantly (P < 0.05) more body weight than did the group fed FSBM. Dry matter (DM) intake was significantly (P < 0.05) lower for the FSBM fed group than for the group fed untreated SBM in exp. 1 (CCS). DM intake was significantly (P < 0.05) increased by either FSBM or SBM over the low CP control fed UCS. Milk protein was the only component significantly (P < 0.05) decreased by FSBM in exp. 1. Isobutyric and isovaleric acids were significantly (P < 0.05) lower in rumen fluid of animals on FSBM plus CCS. Rumen microbial protein content seemed to be more adversely affected by FSBM with CCS than UCS. Amino acid content of FSBM and SBM demonstrated that lysine and tyrosine were lost from SBM after treatment with formaldehyde. The lack of a response in milk production to FSBM is discussed in terms of a lysine and tyrosine deficiency for milk protein synthesis and the adverse effect that formaldehyde protection of SBM may have on the rumen microbial population.

Factors Influencing

Moisture content, hay supplementation and energy content of corn silages were studied as factors affecting dry matter (DM) intake and utilization by lactating cows. In experiment I, a two-week delay in date of harvest resulted in an increase in DM content of silage for the two varieties of corn, but this was associated with significantly greater (P < 005) DM intake and fat-corrected milk production for only the earlier-maturing variety (Pride 5). Harvest date had no influence on solids-not-fat (SNF) content of the milk or body weight, but silage from Pride 5 corn resulted in a significantly (P < 0.05) higher SNF content and greater loss in body weight. In experiment II, feeding 4.7 kg of hay per day significantly reduced (P < 0.05) silage dry-matter intake and increased total ration dry-matter intake but did not change milk production or composition when compared with feeding 2.3 kg of hay per day. In experiment III, ear silage, stalk and leaf silage and hay were compared as a source of roughage for lactating cows. Total ration dry-matter intake was significantly greater (P < 0.05) for hay fed alone, but milk production was apparently higher when the ear silage was fed.

The effects of type of grain (wheat, barley, or sorghum), level of roughage (0, 1, and 2 kg of oaten chaff/head/day) and sodium chloride free choice on the performance of steers of a mean (� S.E.) body weight of 241 � 2 kg fed in yards for a mean period of 133 � 4 days were examined in a factorial experiment. The type of grain, the level of chaff offered to the steers, or the provision of sodium chloride had no significant effect on daily body weight gain (1.08 � 0.03 kg) or efficiency of conversion of feed dry matter (D.M.) to body weight or carcase weight gain (6.5 and 9.7 kg feed D.M./kg gain respectively). Steers fed wheat had a significantly (P<0.01) lower daily D.M. intake than those fed either barley or sorghum grain. The incidence of persistent laminitis, the death of a steer fed barley and the greater number of steers fed wheat not attaining slaughter weight of 385 kg by 180 days indicated that sorghum was probably a 'safer' grain to feed in high-grain rations than either wheat or barley. The level of oaten chaff offered to the steers did not appear to affect the incidence of digestive disturbances. Carcase weight gain represented a mean of 66.8 � 0.7 per cent of the body weight gain during finishing.

Enteric Methane

A quarter of all anthropogenic methane emissions in the United States are from enteric fermentation, primarily from ruminant livestock. This study was undertaken to test the effect of a methane inhibitor, 3-nitrooxypropanol (3NOP), on enteric methane emission in lactating Holstein cows. An experiment was conducted using 48 cows in a randomized block design with a 2-wk covariate period and a 12-wk data collection period. Feed intake, milk production, and fiber digestibility were not affected by the inhibitor. Milk protein and lactose yields were increased by 3NOP. Rumen methane emission was linearly decreased by 3NOP, averaging about 30% lower than the control. Methane emission per unit of feed dry matter intake or per unit of energy-corrected milk were also about 30% less for the 3NOP-treated cows. On average, the body weight gain of 3NOP-treated cows was 80% greater than control cows during the 12-wk experiment. The experiment demonstrated that the methane inhibitor 3NOP, applied at 40 to 80 mg/kg feed dry matter, decreased methane emissions from high-producing dairy cows by 30% and increased body weight gain without negatively affecting feed intake or milk production and composition. The inhibitory effect persisted over 12 wk of treatment, thus offering an effective methane mitigation practice for the livestock industries.

ABSTRACT. This study was design to evaluated about  the using of total mixed fiber ammoniation  (TMFA) in ration on Ballinese beef performance. This study used an experimental method with Completely Randomized Design  (CRD) consisting of 4 types of treatmentt ration based on TMFA  usage level and 3 replications. The treatmentts were  R1 = 60% native grass (Control), R2 = 20% TMFA + 40% native grass, R3 = 40% TMFA + 20% native grass, R4 = 60% TMFA. The ration is added  with a 40% concentrate to obtain 100% ration. The comparison between forage and concentrate is 60:40. Parameters measured in vivo are performance   (ration intake, dry matter intake, crude protein intake, daily body weight gain and  ration efficiency).  The results showed that treatmentt significantly influenced (P <0.05) on  ration intake, dry matter intake, daily body weight gain and ration efficiency, but the treatmentt unsignificantly influenced (P>0.05) on crude protein intake. It can be concluded that the use of 60% TMF ammoniation in the ration shows the best result, that is  ration intake 6.89 kg/head/day, dry matter intake 6.25 kg / head / day, daily weight gain 0.47 kg / head / day and efficiency of ration 7.42%.Pemanfaatan Hasil Samping Pertanian dan Rumput Rawa  sebagai Bahan Amoniasi Total Mixed Fiber  (TMF) dalam Ransum Terhadap Performa Sapi BaliABSTRAK. Penelitian ini mengevaluasi pemanfaatan amoniasi Total Mixed Fiber (TMFA) dalam ransum terhadap performa sapi Bali.

Alfalfa Silage

Triticale (cv. Beaguelita) was compared with barley in concentrate mixes for lactating Holstein cows. Grains in the concentrate mixes were 100% barley (B), 57% barley and 43% triticale (BT) or 14% barley and 86% triticale (T). Alfalfa silage (15% crude protein (CP), 62.2% dry matter (DM) digestibility) was fed ad libitum and the concentrates were fed twice daily at 1 kg per 2.75 kg milk produced. Twenty-one lactating cows were allocated to the three diets for an 11-wk trial with three repeated measures of responses (periods). There were no linear or quadratic effects due to dietary treatments (P > 0.05) on mean dry matter consumption of concentrate and alfalfa silage by cows fed the three diets, with average daily intake of concentrate and forage (kg d−1), respectively being: B, 8.2 and 13.3; BT, 8.8 and 12.2; T, 8.3 and 12.2. Replacing barley with triticale also was not related to 4% fat-corrected milk yield (kg d−1) (P > 0.05) which was 23.6, 26.6 and 24.7 for diets B, BT and T, respectively. Similarly the fat, protein and lactose contents of the milk were not related to the proportions of barley and triticale in the diets. There was a linear reduction in body weight gain as triticale levels increased in the diets (P < 0.05). Rumen fluid pH and ammonia concentration were not affected by triticale levels in the diets. However, the molar concentrations of acetate, propionate, butyrate and valerate tended to increase linearly (P < 0.10) with triticale levels. The rates of disappearance of DM and CP of barley were faster than for triticale from nylon bags incubated in situ in the rumen but the solubilities of DM and CP at zero time of triticale were greater (P < 0.01). Concentrate mixes BT and T containing triticale were readily accepted by dairy cows and supported milk yields similar to one based on barley. However, body weight gain was reduced in cows fed triticale indicating that more of the productive energy was expressed in milk production. Key words: Triticale, barley, lactation

This study investigated the nutritional potency and efficacy of tannin-containing forages as anti-parasites sources to support the performance of female Bligon goats. Fifteen female Bligon goats were divided into 3 different groups based on feeding treatments. The first group (KG) served as the control and was fed 100% king grass (dry matter basis). The second group (KGC) was fed 50% king grass and 50% Calliandra calothyrsus leaves (dry matter basis). The third group (KGA) was fed 50% king grass and 50% Artocarpus heterophyllus leaves (dry matter basis). The study showed that supplementation with tannin-containing forages could improve feed consumption and the digestibility of dry matter (DM), organic matter (OM), and crude protein (CP). The groups that received tannin-containing forages had higher body weight gains at 22.85 g/day and 29.52 g/day for KGC and KGA respectively than the control group. The anti-parasites effects were successfully indicated by the declining number of coccidian oocysts in the feces (number/gram feces), which were 3,166; 841; and 450 for KG, KGC, and KGA respectively. Tannin-containing forage supplementation could improve the consumption and digestibility of DM, OM and CP. Supplementation improved the daily body weight gain. The number of coccidian oocysts in animals receiving supplementation was also reduced. The greatest effects on fecal coccidian oocyst reduction were attained with Jackfruit leaves (Artocarpus heterophyllus) supplementation

Dough Stage

Whole crops of corn, barley, wheat, and forage oats were ensiled and fed as the sole forage to 48 milking cows in two 12-wk feeding trials. In the first experiment corn (25.1% dry matter (DM)) harvested in the early dent stage, barley (34.2% DM), and forage oats (27.6% DM) harvested in the dough stage were compared. Holstein cows fed the three silages averaged 22.6, 19.7, and 18.7 kg of 4% fat-corrected milk per day and consumed 1.67, 1.82, and 1.85 kg of silage DM per 100 kg body weight, respectively. In the second experiment, cows fed wheat (35.7% DM), barley (29.8% DM), or forage oat (27.0% DM) silage harvested in the dough stage produced 21.2, 23.3, and 22.1 kg fat-corrected milk daily and consumed 1.75, 1.71, and 1.62 kg silage DM per 100 kg body weight, respectively. Corn silage DM intake was lower (P < 0.01) but more efficiently utilized for milk production (P < 0.01) than barley or forage oats, whereas wheat, barley, and forage oat silages were similar in feeding value. In experiment I, rumen acetate increased and butyrate decreased with corresponding increases in forage fiber content. Propionate levels were unaffected by the kind of forage, whereas blood urea nitrogen was highest for cows fed forage oats in both experiments.
