Daily Gain

A new oat cultivar, CDC SO-I, with a low lignin hull and high oil groat was evaluated in backgrounding diets for steer calves, with an emphasis on the requirement for processing. Average daily gain was not different (P > 0.05) between calves fed rolled barley, rolled oat, or whole oat diets. Dry matter intake of cattle fed the rolled oat diet was greater (P = 0.04) than that of cattle fed the rolled barley or whole oat diets. Feed:gain was not affected (P = 0.13) by treatment. Results indicate the CDC SO-I oat does not require processing (i.e., rolling), and can replace barley in backgrounding diets with no negative effect on animal performance.

Supplementing a control diet of ground alfalfa (CON) with monensin (MON), chlortetracycline (CTC) or tylosin (TYL) did not affect (P < 0.05) dry matter intake or average daily gain of market lambs. Feed efficiency with CTC was less than with the unsupplemented control (CON) (6.22 vs. 5.68) (P < 0.05). Mean digestibilities of dry matter, acid detergent fiber and neutral detergent fiber were lower (P < 0.05) with all antibiotic treatments than the CON diet. Relative to CON, nitrogen digestibility was increased with MON (66.3 vs. 70.9%) while that of energy was reduced with TYL (P < 0.05). Rumen ammonia and acetic, propionic and butyric acid concentrations were not influenced by any of the treatments. MON, CTC and TYL were not effective supplements for lambs fed alfalfa finishing diets. Key words: lamb, chlortetracycline, monensin, tylosin, alfalfa hay, digestibility

Animal performance and behaviour in fattening steers using ad libitum or restricted feed-bunk management were evaluated. High store-capacity self-feeders with weekly recharge were used in ad libitum management (ADLIB), while manual twice-a-day delivery was used in restricted management (REST). Twenty-four steers were allotted to 12 pens and fed with a high corn-grain diet without roughage, and randomly assigned to one of the treatments. Animal behaviour was recorded every 5 min throughout 24 h for 3 days. No bunk-management effect was evident in bodyweight (P ≥ 0.95) or average daily gain (P = 0.91). Even though ADLIB resulted in higher dry-matter intake (P = 0.03), the animals spent less time per day eating feed than did those under REST (P &lt; 0.01), with more eating sessions per day (P = 0.02), which were shorter (P = 0.06). Rumination time was greater (P = 0.07) under ADLIB than under REST, while the opposite was observed for time spent eating (P &lt; 0.01). Resting time was longer in animals under ADLIB (P = 0.02), with more sessions per day (P = 0.06), than under REST. In conclusion, the two feed-bunk managements evaluated had no negative implications either for animal performance or behaviour.

This study aimed to evaluate the effect of slaughter weight on animal performance, carcass commercial cuts and meat characteristics of Purunã cows feedlot finished. We used 28 cull cows with 68.02±17.36 months of age slaughtered at different weights (461, 476, 434 and 522 kg). The experimental design was completely randomized with four treatments (slaughter weight) and seven replicates (animals). The dry matter intake, expressed as kg d-1 and % of body weight, presented quadratic variation with increasing slaughter weight, with the highest values observed for slaughter weight of 461 kg. The average daily gain decreased linearly, whereas the absolute weight of forequarter, short ribs, and pistol cut linearly increased by the advance of slaughter weight. In relative terms only the short ribs was changed by increase slaughter weight, increasing linearly. Between the proportions of meat cuts prepared for commercialization, linear increases were observed for the chuck and striploin. Increasing slaughter weight promoted linear increases in the scores of color, marbling and palatability, but did not alter the score of tenderness of the meat. The increase of slaughter weight of cull cows of the Purunã breed reduces animal performance, increasing the losses by trimming fat, with important benefits only for the meat palatability.

This study was conducted to determine the accuracy of average daily gain (ADG) predictions based on digestible energy (DE) estimated from acid detergent fiber (ADF) and on the nutrient requirements of beef cattle when applied to growing cattle fed silages of contrasting digestibilities with or without barley. A feeding trial was conducted with 45 Charolais × Simmental calves fed either a control silage (early cut, E) with no barley or two other silages (medium cut, M; late cut, L) fed with (M + barley and L + barley) or without 60% dry-matter (DM) basis rolled barley in the diet. Total dry-matter intake (DMI) of diet E was higher (P < 0.05) than that of diets M and L. The addition of barley in diets M + barley and L + barley led to an increase (P < 0.05) in total DMI. ADG of steers fed diet E was higher (P < 0.05) than that of steers fed diets M and L but lower (P < 0.05) than that of steers fed diets M + barley and L + barley. A digestion trial was conducted concurrently, using five steers fed at 90% ad libitum. The apparent digestibility values of the DM for the five diets tested were (E) 68.5, (M) 60.8, (L) 56.8, (M + barley) 70.8 and (L + barley) 70.1%. Gains predicted when forage DE was estimated from ADF or determined in vivo were, respectively, 57 and 92.6% of observed values. When barley–supplemented diets were studied separately, it was apparent that most of the prediction error was due to the inability to predict forage DE from ADF. Further research is needed to develop methods to accurately predict the energy content of forage silages grown in Canada. Key words: Energy, forages, silages, cattle

Abstract The aim of this trial was to evaluate the effect of encapsulated calcium ammonium nitrate as a partial substitute for soybean meals in the concentrate dry matter intake, average daily gain and feed efficiency of Nellore young bulls under grazing conditions, during the dry season. Sixty-four weaned Nellore (initial BW = 177.46±3.77 kg and 9 mo old) were used in a completely randomized assay. The study lasted 84 days on the dry season. Animals were allotted into 16 paddocks of 1.0 ha each of Urochloa brizantha, randomly assigned into one of two treatments: (CTL) supplement with 25% CP, without nitrate inclusion and; (ENP): supplement with 25% CP, with a inclusion of 50 g of encapsulated calcium ammonium nitrate to each 100 kg of body weight. Animals were fed with concentrate at 1.0% of body weight. Concentrate offered was monitored daily as well as his refusals were collected and weighed to determine daily concentrate dry matter intake (DMI) and feed efficiency (F:G). Animals were weighed every 28 d for calculating average daily gain (ADG). Data were analyzed as a completely randomized design, using ANOVA (α = 0.05). No effects of treatments (P &gt; 0.3487) were observed for final BW (246.69 kg). The same for concentrate dry matter intake (P &gt; 0.0550). Animals consumed 2.34 kg of supplement per day. The average daily gain (0.832 kg, P &gt; 0.2649) and feed efficiency (0.356 kg, P &gt; 0.7315) were not affected by the inclusion of nitrate. The inclusion of encapsulated calcium ammonium nitrate in supplement to Nellore young bulls under grazing conditions during the growing phase did not affect the performance.

The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

Abstract The objective of this study was to evaluate the growth performance and apparent total tract nutrient digestibility of Holstein heifers limit-fed diets containing different amounts of wet brewer’s grains (WBG). A 12-wk randomized complete block study was conducted using 30 yearling Holstein heifers [378 ± 27 d of age, and body weight (BW) of 357.8 ± 27.6 kg (mean ± SD)]. Treatments were 0%, 10% and 20% of WBG on a dry matter (DM) basis and diets were formulated to be limit-fed for dry matter intake (DMI) at 2.35% of BW and provided 15% crude protein (CP) and 2.27 Mcal metabolizable energy/kg of DM. Dry matter intake was recorded daily, while BW and skeletal measurements were measured every 2 wk. During week 12, fecal samples were collected directly from the rectum over four consecutive days and composited by heifer to determine apparent total tract nutrient digestibility using acid detergent insoluble ash as a marker. Data were analyzed using the MIXED procedure of SAS. Dry matter intakes, BW, and average daily gain were not different among treatments (P = 0.2, P = 0.4, and P = 0.6, respectively). Dry matter intakes ranged from 8.6 to 9.0 kg/d. Average BW were 404.4, 411.5, and 409.3 kg for heifers fed the 0%, 10%, and 20% WBG diets, respectively. Average daily gains were 1.03, 1.04, and 0.96 kg/d for heifers fed the 0%, 10%, and 20% WBG diets respectively. Skeletal measurements and body condition scores (BCS) were not different among treatments except for the change in heart girth (P &lt; 0.01) and initial BCS (P &lt; 0.01). Apparent total tract digestibilities of DM, organic matter, CP, fat, and hemicellulose were greater or tended to be greater in heifers fed 0% and 20% WBG treatments than heifers fed 10 % WBG (P = 0.04, P = 0.04, P = 0.06, P = 0.06, and P = 0.01, respectively). Neutral detergent fiber, acid detergent fiber, and fat digestibilities were similar among treatments (P = 0.2, P = 0.3, and P = 0.3, respectively). During the digestibility phase, DMI tended to be greater (P = 0.08) for the 10% WBG treatment. These results demonstrate that limit-feeding heifers with diets containing up to 20% WBG could replace soybean- and corn-based concentrates in diets without adverse consequences to the heifer growth performance.
