Live Yeast

SummaryA trial was run to examine the influence of feeding a rumen specific live yeast, Levucell SC™ (Lallemand Animal Nutrition, Hamilton, New Zealand), on feed intakes and body weights of calves at weaning. Sixty male, Friesian cross calves, aged four days old, were randomly allocated to either a control (unsupplemented) creep feed diet or one containing Levucell SC™, a rumen specific strain of live yeast. All calves were fed a commercial milk replacer (CMR) and offered straw and creep feed ad libitum from entry, and intakes and weight gains were recorded. At six weeks of age, the calves were transferred to grazing with ad libitum access to creep feed and monitored for a further two weeks, covering the transition period from milk to grazing. The calves fed Levucell SC™ had higher feed intakes at weaning (1.105 kg/day versus 1.523 kg/day at seven weeks of age; P = 0.0434 and 1.179 kg/day versus 1.965 kg/day at eight weeks of age; P = 0.0272 for control and Levucell SC™ respectively). Correspondingly, average daily gain (ADG) was improved. At seven weeks of age, ADG was 0.659 kg versus 0.912 kg (P = 0.039), and at eight weeks of age ADG was 0.457 kg versus 0.707 kg (P = 0.0650) for control and Levucell SC™ respectively. It was concluded that supplying Levucell SC™ via creep feed prevented the drop off in calf performance at weaning, in terms of both feed intake and weight gain. This is important, as early rumen development and pre-weaning growth rates are related to a reduction in gastric upsets at weaning, future growth performance in calves and future lactation performance.

Abstract The objectives were to analyze the effects of housing cow-calf pairs in drylots or pasture on calf performance and behavior through weaning. Simmental × Angus (2 yr; 108/yr; 81 ± 15.3 d postpartum) spring-calving cows were stratified by age, BW, BCS, and calf sex and allotted to six groups/yr. Groups were randomly allotted to 1 of 2 treatments: drylot (DL) or pasture (PAST). Calves in the drylot had ad libitum access to a diet consisting of corn silage, dried distillers grain, corn stalks, dry rolled corn, and soybean hulls. Calves on PAST received creep feed three weeks prior to weaning. Calf BW was measured on d 0, 55, and 110. Calves were fence-line weaned on d 110. Behavior was observed for two days after weaning. Data were analyzed using the MIXED procedure of SAS. Drylot calves had greater (P < 0.01) BW at d 55 and 110. There was treatment by time interactions (P < 0.01) for lying and eating on d 111. More PAST calves were lying at h 2 and 3 and eating at h 11 and 12. More DL calves were lying at h 9, 10, 11, and 12. More DL calves were eating at h 2 and tended to at h 3. There was also a treatment by time interaction (P < 0.01) for vocalizations on d 111. More PAST calves vocalized at h 1, however, DL calves vocalized more at h 4 and tended to at h 5. There was treatment by time interactions (P < 0.01) for eating and walking on d 112. More DL calves were eating at h 2, 3, 4, 7, and 9. More PAST calves were walking at h 1 and 2. There was also a treatment by time interaction (P < 0.01) for vocalizations on d 112. More PAST calves vocalized at h 1 and 10. In conclusion, housing cow-calf pairs in drylots improved preweaning performance and altered postweaning behavior.

To determine morphological and molecular characteristics of porcine mammary tissue in vivo, mammary tissue was collected from 18 sows at 3 to 6 d of lactation and 17 to 19 d of lactation using a biopsy technique. The success of the technique was determined by monitoring lactation performance, as evidenced by sow rectal temperature, voluntary feed intake, milk somatic cell count, and piglet average daily gain. Up to 1.7 g of mammary tissue was collected at each biopsy without decreasing sow feed intake or piglet growth. Key words: Biopsy, mammary gland, lactation, sow

The Impact

Abstract The addition of a sensory additive to sow diets during the summer improved feed intake during lactation, and litter performance. The aim of this study was to evaluate the impact of the sensory additive on sow lactation performance during cooler temperatures. Three consecutive groups (n = 61 total) of sows were farrowed during winter (October, December and January). Sows were weighed, and back fat depth was measured, at 110 d of gestation prior to entering the lactation room, and again at weaning. The sows were sorted by parity, and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Spain). Experimental diets were offered upon entry to the lactation room and fed through weaning. Feed disappearance was recorded every three days. Sows were fed 2.72 kg/head/day until farrowing, and then allowed to eat ad libitum from 24 hours post-farrowing until weaning. Data were analyzed using the PROC MIXED procedure of SAS as an RCBD with treatment as the fixed effect and group as a random effect. No differences were observed on sows feed intake (P > 0.4), 10th rib backfat thickness change (P = 0.632) and body weight change from d 110 of gestation to weaning (P = 0.65, Table 1). Sows fed the sensory additive lowered preweaning mortality by 4.9% (P = 0.051), and weaned an additional 1.42 piglets (P = 0.026) with similar weaning weights (P = 0.86) when compared to control. In conclusion, in the current study, lactation diets supplemented with a sensory additive improved litter performance and helped maintain sow body condition.

Abstract Reducing dietary crude protein (CP) with synthetic amino acids (AA) supplementation is beneficial for sustainable swine industry. However some discrepancies regarding the consequences on growth performance are observed. Therefore, this trial aimed to assess the effect of dietary CP level on growth performance of pigs from 35 to 113 kg BW. Growth performance of 63 pigs fed ad libitum and allocated to three groups (HH, MM and LL) was compared. Each group received one level of CP (‘H’ for High, ‘M’ for Medium and ‘L’ for Low) during growing (d0–d35) and finishing (d35–slaugther day) periods: 15.1%, 16.2%, 17.2% and 13.0%, 14.0%, 15.1% respectively. Diets were mostly based on wheat, corn and soybean meal. Within each feeding phase, diets were formulated to be similar in apparent total tract digestible phosphorus, net energy and standardized ileal digestible (SID) essential AA, the SID Lys levels being 0.95% and 0.78% during the growing and finishing period respectively. Data were analyzed using a linear model (R, 3.1.2) with individual as the experimental unit as feed intake, body weight and carcass grading were individually recorded. From d0 to d14 and from d35 to d63, average daily gain (ADG) and Growth:Feed ratio (G:F) were significantly reduced as the CP level decreased (P < 0.05) while average daily feed intake (ADFI) remained unaffected by the dietary treatments. From d14 to d35 and in late finishing period (d63-slaugther day), growth performance was not significantly affected by the dietary CP level. Over the 82-d of the experiment, G:F was significantly higher for ‘HH’ pigs (P < 0.01). Overall, ADG tended to be reduced as CP levels decreased (P = 0.10). There was no difference among treatments for parameters concerning carcass grading (lean meat percentage and meat yield). In conclusion, reducing CP levels while maintaining essential AA levels impaired growth performances of pigs.

A total of seventy-two weaner rabbits of eight weeks of age were used to assess the effects of replacing groundnut cake (GNC) with blood vegetable waste meal (BVWM) in the diets of rabbits. The BVWM was fed to replace dietary GNC at 0, 15, 30, and 45%, with GNC being 15% in the control diet. The four experimental diets were fed ad libitum for a period of eight weeks. BVWM was analyzed to contain a crude protein value of 62.35%. There were comparable feed intake values by rabbits on all the diets although the rabbits in the higher replacement levels of BVWM tended to have consumed more of the feed. There were significant increases (P<0.05) in body weight gain by rabbits as the BVWM level increased in the diet. Similarly, the feed to gain ratio improved and nitrogen digestibility increased (P<0.05) with higher levels of BVWM in the diet. This study shows that rabbits can tolerate the 45% BVWM replacement of groundnut cake effectively.

Lemongrass Oil

An attempt was taken to study the growth performance of lemongrass oil (Cymbopogon citraturs) as a growth promoter on the broiler production. A total of 180day-old broiler chicks were procured from private hatchery (Shivam Hatchery Birgung, Parsa, Nepal) and were allocated following Completely Randomized Design (CRD) into four treatment groups (each treatment with 3 replications and each replication with 15 birds); T1= control, T2= containing lemongrass oil 200 ml/100 kg feed, T3= containing lemongrass oil 400 ml/100 kg feed and, T4= containing lemongrass oil 600 ml/100 kg feed. The study was carried out for 36 days at Avian Research Unit, Regional Agriculture Research Station, Parwanipur, Bara, Nepal. Concentrate mixture and lemongrass oil were procured from Shakti Feed Industry, Birgung; Herbs Processing Plant of Ministry of Forest and Soil Conservation, Jadibuti, Kathmandu, respectively. Experimental birds were provided ad libitum amount of starter feed from 0 to 21 days and finisher feed from 22 to 36 days. Feed intake was recorded daily and body weight gain was measured in 7 days interval. The study revealed that the cumulative feed intake per bird was found higher in T3 (3443.17g) followed by T4 (3377.33g) and T2 (3354.04g), respectively, and were statistically non-significant among the diet groups. The FCR was highest in T3 (1:1.44 kg) and lowest in T4 (1:1.51 kg), and differed insignificantly among the diet groups. Similarly, the total weight gain of the experimental bird was found to be higher in T3 (2385.13g) followed by T1 (2279.46g) and T2 (2271.86g), respectively.  The average daily gain of experimental birds noted higher in T3 (66.25g) followed by T1 and T2 (63.31g) and (63.1g), respectively. The experiment suggested that inclusion of lemongrass oil could be considered as an alternative to antibiotic growth promoter in broiler diet to enhance the production performance.

ABSTRACT The present study aimed to evaluate the feedlot performance, profitability and carcass traits of Brahman bulls classified according to the residual feed intake (RFI). Twenty-four bulls (19-month old, 370±34kg live weight) were housed in individual pens for 54 days and had the daily feed intake (observed dry matter intake, DMIobs; DMI % live weight, LW) and average daily gain (ADG) measured. Ultrasound carcass evaluations were performed at the initial and final weighings, when measurements were taken of Longissimus dorsi area, ratio, Longissimus and Biceps femoris fat thickness. The animals were ranked and divided into high (>+0.5 standard deviation; SD), medium (between ±0.5 SD from the mean), and low (<-0.5 SD) RFI groups. Low-RFI animals had lower DMIobs (P<0.10) and DMI % LW (P<0.05). No significant differences in initial and final weight or ADG were noticed (P>0.05). Low-RFI animals showed lower weight gain cost and higher daily profit (P<0.05). Carcass traits were similar between groups, regardless of evaluation date (P>0.05). Selection for RFI lead to animals with lower feed intake without affecting weight gain or carcass traits, thereby providing increased profitability for beef cattle farming.

SUMMARYIn an experiment with group-fed cattle from 6 months of age to slaughter at 480 kg live weight two levels of feed intake: 1, ad libitum, 2, 85% of ad libitum amount, were combined with two ratios of concentrate to hay: a, 70: 30; b, 30: 70. In two further treatments, 3a and 3b, the cattle were fed diets a or b at 70% of ad libitum from 6 to 10 months and ad libitum thereafter.Daily gain during the first 124 days of the experiment was (in grams) 1293, 983, 1097, 846, 992 and 756, and from the 125th day to slaughter 735, 600, 796, 579, 830 and 714, for treatments la, lb, 2a, 2b, 3a and 3b, respectively. The decline in rate of gain from the first period to the second was inversely related to the level of feed intake and to the percentage of concentrates in the ration in the first period.Daily carcass gain was 582, 393, 532, 350, 531 and 368 g for treatments la, lb, 2a, 2b, 3a and 3b, respectively.The treatments that were switched over from 70% of ad libitum feed intake in the first period to 100% in the second (3a and 3b), exhibited considerable compensatory growth in the second period, but this was not sufficient to be of economic advantage.The overall ME requirement per kg of live-weight gain was inversely related to rate of gain. Of the six treatments, 2a (85% of ad libitum, 70% concentrate) was the most efficient (19·8 Mcal/kg live-weight gain).Animals on the 100% level of feed intake throughout the experiment (treatments la, lb) were significantly fatter than those on the other treatments.

A study involving three sets of data from the University of Alberta beef breeding herd (1966–67, 176 cows; 1967–68, 167 cows; 1968–70, 285 cows) was conducted to determine the influence of birth weight of calf (BW), postcalving weight of dam (PCW), and breed effect on calf performance to 365 days of age. The influence of preweaning on postweaning performance was also considered. Calves heavier at birth tended to excel in both preweaning and postweaning growth rate. A 1-kg increase in BW resulted in an increase of 2.86–4.42 kg in calf weight at 365 days of age. For male calves, PCW was negatively associated with calf weight at both 180 and 365 days of age for 1966–67 data; however, for 1967–68 and 1968–70 data, a 10-kg increase in PCW resulted in 0.70- and 0.92-kg increases, respectively, in calf weight at 180 days, and 1.96- and 2.12-kg increases in calf weight at 365 days, respectively. For female calves, a 10-kg increase in PCW resulted in 1.40-, 0.88-, and 0.29-kg increases in calf weight at 180 days of age, and 0.68-, 1.31-, and 0.31-kg increases in calf weight at 365 days of age, respectively, for the three sets of data. Breed difference explained from 22 to 43% of the variance in average daily gain of calf to weaning (ADG) but only 0.2–13.8% of the variance in postweaning average daily gain (PWADG). Male calves with higher ADG to weaning or heavier weaning weights tended to have slightly higher PWADG. A 10-kg advantage in weaning weight for male calves resulted in a 12–14-kg advantage in weight at 365 days of age.

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.
