The objective of this study was to evaluate the performance of beef heifers on Stapf. cv. Marandu grass pastures that were managed at three herbage allowances under continuous grazing with a variable stocking rate and were provided with mineral mix supplement or supplements with energy and protein. Seventy-two test heifers and 48 put-and-take heifers were used in a randomised design in a 3 × 2 factorial arrangement [three herbage allowances (1.5, 2.0, and 2.5 kg of green dry matter/kg of bodyweight, and two supplementation levels (mineral mix or 0.3% bodyweight of a mineral–protein–energy supplement)], with two replicates per treatment (paddocks), to maintain the pre-established forage allowance. No significant difference was observed in the gain per hectare as a function of the herbage allowance, but 2.5 kg green dry matter/kg bodyweight provided the greatest average daily gain of bodyweight (0.605 kg/animal/day). The energy/protein supplementation provided the greatest average daily gain compared with animals fed only the mineral mix. The supplements in the diet of beef heifers fed at 0.3% of bodyweight increased bodyweight gains without compromising the gain per hectare at different herbage allowances.

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance.

This study evaluated food intake and productive performance of crossbred (½ Santa Inês x ½ dorper) lambs supplemented with different levels of faveleira (Cnidoscolus quercifolius Pohl) fodder salt. Thirty male sheep fed tifton grass hay, water, and faveleira fodder salt were randomly allocated into five treatments with six replicates each. The treatments consisted of diets with different inclusion levels of faveleira hay in the fodder salt composition: Treatment 1 (1% mineral salt + 99% faveleira hay), Treatment 2 (3% mineral salt + 97% faveleira hay), Treatment 3 (5% mineral salt + 95% faveleira hay), Treatment 4 (7% mineral salt + 93% faveleira hay), and Treatment 5 (Control - 100% mineral salt). Intake of dry matter, tifton hay and water, average daily gain, feed conversion, and feed efficiency were not affected by fodder salt supplementation (P > 0.05). There was a significant difference (P < 0.05) in fodder salt intake between Treatments 4 and 5, and daily intake was higher in animals submitted to Treatment 4 (61.0 g day-1). Mineral salt intake increased significantly with increasing mineral salt levels in the diet. However, no significant difference was observed in average daily gain across treatments, indicating that faveleira hay, even in small quantities, and tifton hay were able to meet the nutritional requirements of animals to support a good average daily gain. The inclusion of up to 99% faveleira hay in fodder salt formulations did not affect voluntary intake of forage, water and dry matter, average daily gain, feed conversion, and feed efficiency. Lambs supplemented with faveleira fodder salt had average daily gains within the optimal range for slaughter and high feed conversion and feed efficiency values. Faveleira was shown to be an effective supplementary feed alternative in sheep.

SUMMARYHerbage allowance (HA) impacts performance of grazing cattle as well as sward structure and herbage yield. The objective of the current study was to compare average daily gain (ADG) of Nellore steers on Marandu palisadegrass (Brachiaria brizantha (Hochst ex A. Rich.) Stapf. cv. Marandu) pastures in response to HA. Treatments were applied as 5, 10, 15 and 20 kg dry matter (DM) per 100 kg live weight (LW) per day HA5, HA10, HA15 and HA20), in rotationally stocked pastures under a 35-day grazing cycle (28 days of rest and 7 days of grazing). The trial was carried out in Pirassununga, Brazil, during two summer seasons in 2003 and 2004, each divided into four grazing cycles. Individual animal (250 kg yearling steers) gain increased with HA up to HA15 (mean=0·69 kg/head per day) during each of four grazing cycles per year. The 2-year gain per area was greater for HA5 and HA10 than for HA15 and HA20 and average stocking rate was 9·6, 6·7, 5·4 and 4·6 head/ha for HA5 to HA20, respectively. In addition to the effects of HA on ADG, changes in sward structure, especially sward height, help to explain variation in daily gain in both years. The HA10 treatment provides higher gain per area without excessively reducing individual animal performance, and thus may be the level of choice for optimizing animal output in pasture-only systems.

ABSTRACT The use of different types of concentrated supplements on the performance of Nellore calves grazing Urochloa brizantha cv. Marandu in the dry season was evaluated. The experiment was conducted on 24 ha divided into 12 paddocks. Seventy-two calves with initial body weight (BW) 176±14kg for 140 days of experiment were used. Evaluated treatments included: Mineral, Salt+urea (mineral with 30% urea), Protein (supplementation with 45% crude protein (CP) and 46% total digestible nutrients (TDN)); and Protein+energy (with 28% CP and 73% TDN). The Mineral, Salt+urea, and Protein were offered ad libitum, and the Protein+energy 5g/kg BW. Protein+energy showed the highest (P< 0.05) intake (3.66g/kg BW) followed by the Protein (1.61), Salt+urea (0.36), and Mineral (0.32). The two latter supplements were not significantly different (P> 0.05). The highest (P< 0.05) average daily gain (ADG, kg/day) was observed in the Protein+energy (0.074). Average daily gains for the Protein and Salt+urea (0.014 and -0.024, respectively) were not significantly different (P> 0.05), but were significantly higher (P< 0.05) than the Mineral (-0.085). Therefore, during the dry season, to prevent the loss of bovine weight the supplements must supply in addition to minerals, also energy, non-protein nitrogen (NNP), and true protein.

This meta-analysis evaluates the effects of yeast supplementation (Saccharomyces cerevisiae) on dry matter intake (DMI) and average daily gain (ADG) in beef cattle. The inclusion criteria were complete and randomized trials and supplementation with yeast S. cerevisiae versus no supplementation to measure DMI or ADG. Data were extracted from relevant papers via pre-defined protocols. A meta-analysis of random effects was conducted for each indicator separately including the mean of the control and treated groups. The results were presented with the pooled mean difference (MD), 95% of confidence interval, and I² (percentage of total variation between studies that is due to heterogeneity rather than chance). A total of 12 publications reporting 22 trials conducted in 1,161 cattle were analysed. The heterogeneity between studies was high and ranged from 92 to 99%. No effects were observed in ADG with the inclusion of yeast in the diet (MD = -2.849 g/day, p = 0.492). However, there was a reduction in the DMI (MD = -0.885 kg/day; p = 0.023) despite the high heterogeneity among studies (I2 = 92.4%; p < 0.001). The ADG increased when the forage level in the diet was between 30 and 50% (MD = 641.08 g/day; p = 0.001) and decreased when the level range from 51 to 75% (MD = -2.90 g/day; p < 0.001). In over 60% of the Neutral Detergent Fibre, the use of yeast in the diet decreased the ADG by 406.94 g/day (p = 0.034). Feedlot animals showed a reduction in the DMI (MD = -0.97 kg/day; p = 0.019) if supplemented with yeast. Supplementation with S. cerevisiae in the diet of beef cattle had no effect on ADG; however, it does improve the feed conversion due to the reduction in DMI.

Kochia (Kochia scoparia (L.) Schrad.) was grown on land irrigated with packinghouse wastewater and ensiled in a plastic silo bag. Kochia dry matter (DM) yield and acid-detergent fiber (ADF), Na, Mg, Mn, and Cu contents (DM basis) were correlated with some soil measurements. Alfalfa silage was replaced with kochia silage in a basal diet at levels of one-half (35% of diet DM) or all (70% of diet DM) of the roughage. The diets were fed to 120 calves (initial weight 294 kg) for 70 d in a completely randomized experiment with three treatments (kochia, kochia and alfalfa, and alfalfa) and four pen replicates. Inclusion of either 35 or 70% kochia silage in the diet DM depressed (P < 0.01) DM intake (DMI) by 23.3 and 50.1%, respectively, compared with calves fed the basal diet. Average daily gain (ADG) and final bodyweight of the calves fed kochia silage were both less (P < 0.01) than those fed the basal diet. DM conversion to liveweight gain ratios (DM: G) were 13.91, 8.42, and 7.15 when the diets contained (DM basis) 70, 35, or 0% kochia silage, respectively. Over the 42-d period following the trial, the calves that had received kochia silage tended (P = 0.078) to gain faster than those that had been fed the basal diet. The reduction in DMI observed when kochia silage was fed appeared to be the result of advanced maturity and weather damage of the kochia and not due to apparent toxic effects.

The objective of this research was to determine the potential uses of dry matter in the average daily gain of beef cattle and rice straw carrying capacity as a feed alternative. The research used an analytical survey approach, and the location was chosen via purposive sampling. Data collection consisted of conducting interviews and observations based on a questionnaire; then, the collected data were tabulated and analyzed using descriptive statistics. Spearman’s correlation coefficient was used to determine the relationship between dry matter intake level and average daily gain; simple linear regression analysis was used to measure the effect of dry matter intake level on average daily gain. The results revealed that the average daily gain of beef cattle in North Samarinda, Palaran, Sambutan, and Samarinda Ulu (Indonesia) was 0.44 kg, 0.45 kg, 0.45 kg, and 0.45 kg, respectively. The analysis results of dry matter intake level on average daily gain obtained via the regression equation (Y) were as follows: Ỷ = 0.013 + 0.945X. This indicates that every intake of 0.945 kg of dry matter would yield an average daily gain increase of 0.013 kg. Effective utilization of available abundant feed resources (rice straw) is the key to economic maintenance of cattle; however, it tends to have low nutrition and low digestibility, so it is not given as a single feed because it cannot meet beef cattle’s dietary needs. This research found that rice straw production (each hectare of rice area) was able to supply alternative feed for beef cattle of 2.7 animal units per year.

Energy Supplementation

The objective of this study was to evaluate the effect of the frequency of provision of protein energy supplementation on pasture during the dry period of the year on the performance of Nelore steers in rearing phase. FAZU teaching school conducted the experiment from July to September 2017. Twenty-two animals of the Nelore breed, aged 12 months and mean initial weight of 232.22 (± 20) kg, modules of 2 ha each, subdivided in six paddocks of Panicum maximum cultivars Mombaça and Tanzânia. The experimental design was completely randomized (DIC) and the averages were compared by the Tukey test at 5% significance. There was no significant difference between the three frequencies of supply of energy protein supplementation, in relation to the average daily weight gain, which were 837; 881 and 855g, at the frequencies of 7; 5 and 3 times per week, respectively. However, there was a significant difference (P <0.05) for the mean daily weight gain between the treatment in which the animals received mineral supplementation (434g), which was lower than the treatments in which the animals were fed with protein energy supplement at the level of 0.25% of body weight. In conclusion, during the period and in the evaluation conditions of this experiment, there was no difference in the effect of the frequency of supply of a protein energy supplement in the supply level of 0.25% of the animals' body weight. The average daily gain was higher for the animals that received the protein energy supplement compared to those supplemented with mineral. Five times a week supplementation obtained the best economic benefit among the evaluated frequencies.

Abstract. Hartatik T., Fathoni A, Bintara S., Ismaya, Panjono, Widyobroto B.P, Agus A, Budisatria I.G.S, Leroy P. 2020. Short communication: The genotype of growth hormone gene that affects the birth weight and average daily gain in crossbred beef cattle. Biodiversitas 21: 941-945. Growth Hormone gene has been proposed to direct search for quantitative trait loci, and polymorphisms at these loci have been associated with several production traits in bovine. This research aimed to investigate the association of the genotype of partial growth hormone gene with birth weight and average daily gain in crossbred beef cattle. The materials of this research consist of 47 samples from four different breeds. Birth weight was measured just after calving delivery from the mother. The average daily gain was calculated from the period since birth weight to the second weight (90 days). Genotyping of the growth hormone gene was determined by the sequencing and PCR-RFLP method with the AluI restriction enzyme. The association between genotype and growth traits data was analyzed using analysis of variance (ANOVA) by RStudio version 1.1.383. The results showed the significantly different (P<0.001) in birth weight and average daily gain according to the different breed. Friesian Holstein breed showed the highest birth weight, followed by Belgian Blue Bull cross and others. The genotype valine/valine only occurs in Belgian blue bull cross and Wagyu bull cross cattle and showed moderate birth weight. Genotype affects birth weight significantly (P<0.001). The birth weight for genotype leucine/leucine, leucine/valine, and valine/valine was 34.82±18.13, 25.31±13.10, and 29.35±13.65, respectively. There was no significant difference in average daily genes according to the different genotypes. In conclusion, the growth hormone gene was probably one of the molecular genetics markers for excellent growth traits in different crossbred beef cattle.

Corn for silage was planted at two seeding rates (60 000 and 200 000 kernels ha−1) in three consecutive years and evaluated by determining yields, digestibility by sheep and performance of growing-fattening beef cattle fed the ensiled crops. Plant populations at harvest ranged over years from 53 000 to 63 000 plants ha−1 for conventional seeding and from 94 000 to 151 000 plants ha−1 for the dense seeding rate. Dense seeding increased whole-plant dry matter yield each year. Only in 1 year (1979) did dense seeding reduce the yield of dry matter in the whole ear or grain (P < 0.01). In the same crop year (1979) dense seeding reduced the dry matter and crude protein contents of the silage (P < 0.01) and the digestibilities by sheep of the dry matter and nitrogen were lower (P < 0.01) than for the conventionally seeded crop. In 2 years (1978 and 1979), when the silages were fed ad libitum with only a protein-mineral-vitamin supplement, the daily silage dry matter intake by beef cattle was lower (P < 0.01 or P < 0.05) and in 1979 the average daily gain (1.06 vs. 1.14 kg d−1) was lower (P < 0.01) with silage from the dense seeding. There were no significant differences in beef performance parameters (silage dry matter intake, daily gain, and efficiency of silage conversion to daily gain) in the third year when the silages were fed with ground barley. Dense seeding of corn for silage resulted in more beef production per hectare and provides a means of reducing productivity loss due to birds feeding on the ripening ears of corn.
