PSIV-B-24 Late-Breaking: Effect of initial body weight variation on growth performance of finishing Nellore cattle

Abstract The increased number of beef cattle entering feedlot operations in Brazil has increased, thus leading to increased productivity, livestock density rate, and improved carcass traits. The age and condition in which animals enter the feedlot is often neglected and may result in increased pen heterogeneity and might impact the growth development of the animals. The objective of this study was to evaluate the effect of the initial weight variation indicator (IWVI) on confined Nellore breeds on productive performance. A total of 382 pens (38,850 animals) were evaluated for 90 days. The variables evaluated were (IWVI), average daily gain (ADG), gain efficiency (G:F) and net feed conversion (nFC). The experimental design was determined by the amplitude of the mean and high volume of homogeneity. A non-parametric analysis was performed using the Kruskal-Wallis test for the comparison of groups, and there was a significant difference using the Mann-Whitney test for the comparison of experimental groups 2 to 2. Significance was determined at (P < 0.017). The highest ADG was 1.59 kg, observed for the pens with lower IWVI. The lowest ADG was 1.46 kg, observed in the pens with higher IWVI. The lower IWVI showed higher G:F (6.36) and nFC (131.01 kg) compared to more variable initial weight pens (1.82 and 148.09 kg, respectively). Lower initial weight variations per pen had a positive effect on average daily gain, gain efficiency and net feed conversion. Initial body weight variation seems to be an important factor feedlots should consider upon Nellore cattle arrival.

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

Stimulation Of

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.

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.

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.

The objective of this experiment was to evaluate the effects of metabolizable energy (ME) levels in diets with high digestible lysine concentration on performance, carcass traits, and meat quality of barrows from 95 to 158 days of age. Eighty commercial hybrid barrows (50 ± 1.82 kg) selected for lean meat deposition, were assigned to four dietary treatments (3,150, 3,235, 3,320, and 3,400 kcal EM kg-1) in a randomized design with 10 replicate pens per treatment and two pigs per pen. From 95 to 116 days of age, we observed no effects of ME on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME levels (? = 5.79961 - 0.00096790X - r2 = 0.89). From 95 to 137 days of age, no effects of ME were observed on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME (?= 6.1176 - 0.001X - r2= 0.97). From 95 to 158 days, of age no effects of ME were observed on FBW and ADG. Dietary ME influenced the ADFI and F: G, which decreased linearly with increasing ME concentrations (?= 8.12951 - 0.00149X - r2= 0.99; ?= 6.0914 - 0.001X - r² = 0.75, respectively). There was a linear increase in loin eye area (LEA) with increasing ME (? = - 29.851 + 0.0207 X - r² = 0.87). Backfat thickness, pH, and temperature, measured at different times after slaughter (0 min, 45 min, 3 h, and 24 h), were not affected by dietary ME. The level of ME also did not affect the meat quality parameters Color L*, Color a*, Color b*, Warner-Bratzler shear force, thaw water losses, cooking water losses, sum of water losses, intramuscular fat content, and TBARS. Diets with 3,400 kcal kg-1 ME, corresponding to 2.75, 2.57, and 2.31 g digestible lysine/Mcal of ME for pigs from 95 to 116, 116 to 137, and 95 to 158 days of age, respectively, resulted in best performance and carcass traits, without negative effects on meat quality.

Twenty-four male Santa Ines animals were used, with initial body weight of 19.77 ± 1.95 kg and average age of 160 days. The animals were distributed in three treatments (Tifton 85 hay-TH, Maniçoba hay-MH and Maniçoba silage-MS), arranged in a randomized blocks design, with 8 replicates per treatment. The feedlot period lasted for 71 days. The means of the variables were tested by Tukey’s test at 5% probability. Sheep fed MH presented higher dry matter intake (p > 0.05) than those fed TH (1.17 kg day-1 vs 1.06 kg day-1). Neutral detergent fiber intake was higher (p > 0.05) for MH-fed sheep (0.394 kg day-1) when compared to MS (0.340 kg day-1). The digestibility of total carbohydrates was higher (p > 0.05) for MH diet (0.71 g kg-1) than TH (0.67 g kg-1). The average daily gain and body weight at slaughter did not differ (p > 0.05) among treatments. Maniçoba hay or silage can replace Tifton 85 hay in sheep diets.

The effect of feeding barley-wheat-soya finisher, gestation and lactation diets containing (A) 1979 National Research Council (NRC) recommended calcium-phosphorus (Ca-P) levels or (B) 150% of NRC levels from 65 kg body weight (Bwt) on growth and reproduction was studied in two experiments using Lacombe (L) and Yorkshire (Y) gilts. The number of gilts used were 299 (148 L + 151 Y) and 107 (53 Y + 54 Y) in exp. 1 and 216 (106 L + 110 Y) and 101 (49 L + 52 Y) in exp. 2 during finishing and gestation-lactation periods, respectively. The reproductive performance during second parity was measured only in exp. 2 using 85 (36 L + 49 Y) primiparous sows. All pigs were housed in confinement except during breeding and gestation, when they were housed in outside dirt-lot pens. Average daily gain, feed intake, and feed conversion were similar for gilts fed finisher diets A or B in both experiments. In exp. 1, both L and Y gilts fed gestation diet B had more (P < 0.05) total (9.5 ± 0.3 vs. 8.6 ± 0.3) and live pigs (9.2 ± 0.3 vs. 8.2 ± 0.3) born and weaned (7.7 ± 0.3 vs 6.9 ± 0.2) with lower piglet weight gains at 3 wk (3.5 ± 0.1 vs. 3.9 ± 0.1 kg) and 5 wk (6.9 ± 0.2 vs. 7.5 ± 0.2 kg) when compared to gestation diet A group. These differences were not significant in exp. 2. Higher dietary Ca-P levels elevated the serum P during both gestation (7.3 ± 0.1 vs. 7.0 ± 0.1 mg/dL) and lactation (6.2 ± 0.1 vs. 5.9 ± 0.1 mg/dL) periods in exp. 1 but not in exp. 2. The changes in body weight during gestation and lactation, piglet birth weights, and weaning to estrus interval were similar for both treatment groups. These results indicated that the 1979 NRC recommended dietary Ca-P levels may be adequate to support the maximum growth and reproduction in gilts during finishing and lactation but are too low for gestation.

S. alba leaves and A. lanata leaves are forages that grow in mangrove ecosystems which are considered potential to support the performance of goat jawarandu. This study aims to determine the effect of the leaves of S. alba and A. lanata on the performance of jawarandu goats. This research was conducted in Environment XII of Seberang Fishermen Village, Belawan I Village, Medan Belawan District, Medan City. The study lasted for 3 months, starting in July to October 2019. The research method was a completely randomized design (CRD) with 3 treatments and 4 replications so that there were 12 male goats that were kept with an average initial body weight of 14.65 ± 1.65. The treatments given were leaves of S. alba and A. lanata with a ratio of P1 (100: 0); P2 (50:50); and P3 (0: 100). The research parameters are Feed Consumption, Average Daily Gain , and Feed Conversion. The results showed that the utilization of the S. alba and A. lanata leaves had a significant effect on feed consumption and average daily gain, but did not significantly effect on feed conversion. It can be concluded that the utilization of S. alba leaves gives a greater effect on the performance of goat jawarandu compared to A. lanata leaves or combination feed.
