A growth experiment was conducted to study the effect of different lysine supplementation levels of barley wet distillers’ solids (WDS) diets on the performance and the carcass quality of pigs (25.5-95.5 kg live weight). A total of 160 pigs were divided into four groups of 40 animals. Four pigs of the same sex were placed in each pen and fed one of the four experimental diets; a barley-soyabean meal (SBM) control diet (167 g crude protein (CP) /kg dry matter (DM) and 7.6 g lysine/feed unit (FU)) or three similar barley-WDS diets (204 g CP/kg DM) which were supplemented with synthetic lysine to contain 7.7, 9.2 or 10.7 g lysine/FU. Lysine supplementation linearly improved the daily weight gain (DG) and feed conversion ratio (FCR) of the pigs during growing (1-5 weeks) (p < 0.001), finishing (6th week onward) (p < 0.001) and the whole experimental period (p < 0.001). However, during the whole growing-finishing period the performance of the pigs levelled off at the lysine level of 9.2 g/FU and daily supply of 18.0 g, respectively(quadratic effect: p < 0.05 for DG and p < 0.01 for FCR). The pigs on the SBM diet grew faster and more efficiently than did the pigs on the WDS diets with similar lysine content (p < 0.05).

A growth experiment was conducted using 50 pigs (25-100 kg) to evaluate the use of meat and bone meals of different ash content as a substitute for soyabean meal (SBM) for growing pigs and the potential of 1-fluoro-2,4-dinitrobenzene (FDNB) reactive lysine in diet formulation. The control diet consisted of barley and SBM. For test diets, either 33 or 67% of SBM was replaced with meat and bone meal of low (ML, 205 g ash/kg) or high (MH, 349 g ash/kg) ash content. SBM, ML33, ML67, MH33 and MH67 diets contained 7.8, 7.8, 8.2, 7.8 and 7.9 g FDNB-reactive lysine/feed unit (feed unit is equivalent to 9.3 MJ NE), respectively. For these diets, average daily live weight gains (ADG) were 859, 830, 805, 854 and 813 g/d with feed conversion ratios of 2.25, 2.40, 2.41, 2.31 and 2.44 feed units/kg, respectively. Pigs fed the SBM diet grew faster (P

SUMMARYThe nutritional value of a pelleted fattening concentrate mixture, in which heat-sterilized poultry litter (PL) was included at rates of 0, 15, 25 and 35%, was studied. A digestion and nitrogen balance trial was carried out with rams, and a feeding trial was carried out with intact male cattle from the age of 8 mo to slaughter at 14 mo.Digestibility of crude protein was related inversely to PL content of the diet. This decrease in digestibility was not accompanied by a decrease in the quality of the protein digested.Gross and digestible energy contents of the diets were related inversely to their PL content. There were no significant differences in blood urea concentration. A concentrate mixture containing 1% urea but otherwise similar to the control, was included in the feeding trial.There were no significant differences in rate of live-weight or carcass gain between treatments. The differences in degree of fatness of the carcasses tended to be related inversely to PL% in the diet, but they were small and reached significance only with the extreme treatments. Feed intake on PL-containing diets was higher than on the control diet, but feed conversion efficiency was impaired when the proportion of PL exceeded 25%. No significant correlations were found between total volatile fatty acids in rumen liquor and daily live-weight gain.

Both digestibility and performance experiments were carried out to evaluate the nutritive value of triticale for growing-finishing pigs.In experiment 1,the apparent ileal and faecal digestibility of nutrients in barley (Hordeum vulgare cv.Viivi)and two triticale (Tritico secale cultivars, Moreno and Ulrika, were measured using six cannulated barrows with a body weight (BW)of 82-107 kg.In experiment 2,132 pigs were used over 25-100 kg BW to study the effects of replacing barley in a barley-soyabean meal-based diet with graded amounts of triticale cv.Moreno (25,50,75,or 100%) and cv.Ulrika (50 or 100%).The apparent ileal and faecal digestibilities of dry matter and organic matter were higher for both triticale cultivars than for barley (P 0.05).The apparent ileal digestibility of lysine averaged 65.6, 70.8, and 70.5% for barley and triticale cv.Moreno and Ulrika,respectively.The net energy content of triticales (11.5 MJ kg-1 DM)was 0.4 MJ kg -1 DM higher than that of barley.The replacement of barley with the triticale cultivars Moreno and Ulrika exerted a positive quadratic effect on daily weight gain and the feed conversion ratio of pigs from 50 to 100 kg and from 25 to 100 kg BW (P

Randomized Experimental Design

The aim of this study was to evaluate the performance of crossbred Holstein × Zebu steers fed on the diets containing sugarcane in natura or ensiled with two levels of concentrate (30% and 70%). A total of 32 males of 394 kg of body weight were used in a completely randomized experimental design with four treatments and seven repetitions. The animals reported a high dry matter intake (DMI) (P < 0.05) when fed on the high concentrate levels. The increase in concentrate levels resulted in an approximately 25% to 60% higher DMI as compared to the lowest level offered by silage-based diets and sugarcane in natura. The highest apparent digestibility coefficients of dry matter were observed in the diets based on sugarcane in natura (P < 0.05). The sugarcane based diets also affected (P > 0.05) the digestibility of organic matter, neutral detergent fiber, crude protein, ether extract, and non-fiber carbohydrates. There were no differences (P > 0.05) between the diets for average daily weight gain, carcass dressing, carcass gain, and feed conversion. The diets based on sugarcane in nature or ensiled with 30% and 70% concentrates do not influence the performance of crossbred Holstein × Zebu cattle.

SUMMARY1. Seventy-two individually fed pigs on six treatments were used to determine the effects on performance and in particular on carcass quality of (a) giving quantities of liquid skim-milk (preserved with formalin) in excess of those normally recommended; (b) replacing meal by skim-milk in the ration on a calculated dry-matter basis (1 gal. skim-milk equivalent to 1 · 1 lb. meal) as compared with a calculated energy basis (1 gal. skim-milk equivalent to 1 · 3 lb. meal) and (c) giving skim-milk for only a part of the growing period instead of throughout. The experimental period continued from 9–10 weeks of age until slaughter at an average live-weight of 135 lb.2. Extensive carcass measurements were taken and in addition assessment of the carcasses was made by a representative of the County Quality Pork Association and by an expert pork butcher.3. Carcasses from pigs given an all-meal diet were comparable in all respects with those from pigs given skim-milk throughout up to a maximum of either 5¼ or 10½ pints per pig per day.4. Carcasses from pigs given the highest level of skim-milk (maximum of 15¾ pints per pig per day) were superior in many respects to those on any of the other treatments, but the possibility that this was due to their slower rate of growth rather than to the high level of milk per se, is discussed.5. Pigs given skim-milk as replacement of part of their meal allowance on a calculated dry matter basis grew significantly faster than those in which the replacement was made on a calculated energy basis or than those given an all-meal diet. The importance is stressed of ensuring that in assessing the value of skim-milk for pigs the caloric value of the rations being compared is similar. The need for experiments based on actual determinations of the caloric value of the rations used is also emphasised.6. While the performance of pigs given skim-milk up to 75 lb. live-weight only was similar to that of pigs given skim-milk throughout, evidence was obtained that the quality of their carcasses was slightly inferior.7. There was some suggestion that as the level of skim-milk in the diet increased an eye muscle of a rather paler colour was produced.

Urea Addition

SUMMARYFifty-four British Friesian castrated male calves, initially 3, 6 or 9 months of age (107, 180 and 249 kg initial live weight, respectively), were individually fed for 83 days on maize silage (27·9% dry matter (D.M.), 10·7% crude protein in D.M.), offeredad libitum. Silage was offered either alone or supplemented with cobs of dried lucerne (21% of total D.M. intake). Three levels of urea (0, 1 and 2% of silage D.M.) were added to the silage before feeding.Total D.M. intakes averaged 23·0, 23·4 and 21·6 g/kg live weight (LW) for the 3-, 6- and 9-month-old animals, respectively. Addition of urea increased silage intake by 11% in the 6-month-old group but there was little effect in the 3- and 9-month-old groups. Lucerne supplementation reduced silage D.M. intake from 22·0 to 18·4 g/kg LW (P< 0·001) and increased total D.M. intake by 1·4 g/kg LW (P< 0·001).Live-weight gain (LWG) of the cattle fed on silage alone increased (P< 0·001) with increasing age of animal. The main effect of urea was to elevate (P< 0·001) LWG from an average of 0·79 (no urea) to 0·94 kg/head/day (2% urea). However, it appeared that most of this effect was confined to the 6-month-old group. The effect of lucerne on LWG decreased with increasing age of animal (P< 0·001). Inclusion of lucerne in the diet significantly reduced the response to urea (P< 0·05).Feed conversion efficiency (LWG/100 Mcal DE intake) decreased (P< 0·01) with increasing age of animal but increased with urea addition from an average of 4·7 (no urea) to 5·3 kg LWG/100 Meal DE intake (2% urea). The response to lucerne supplementation in terms of efficiency was greatest in the 3-month-old group and thereafter declined markedly with increasing age of animal.The results of this experiment indicated that cattle older than 6 months of age (180 kg LW) could achieve a rate of growth of 1·0 kg/head/day on maize silage supplemented solely with urea, but that younger animals required supplementary lucerne to support a high rate of live-weight gain.

A total of thirty-four Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls with an average weight of 284 kg were included in the experiment and fed ad libitum two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal and lucerne silages) with different concentrations of dietary energy until slaughter at the target live weight of 600 kg. The CF bulls consumed more dry matter (DM) of feed daily than the CH bulls (<i>P</i> < 0.05) and gained weight less efficiently than the CH × CF and CH animals (<i>P</i> < 0.01) during the entire experiment. The killing-out percentage was lower in the CF than in the CH × CF and CH (<i>P</i> < 0.05). The CH bulls received a higher score for carcass conformation and a lower score for carcass fatness (<i>P</i> < 0.01) than the CF bulls, had lower proportions of kidney and cod fat (<i>P</i> < 0.01) than the CH × CF and CF bulls, and produced the highest percentage of high-priced meat (<i>P</i> < 0.05) and the lowest percentage of separable fat (<i>P</i> < 0.001). The bulls on the MS diet were younger than the others at the end of the experiment (<i>P</i> < 0.01), gained weight more rapidly (<i>P</i> < 0.001), consumed less DM (<i>P</i> < 0.001) daily, utilized nutrients more efficiently over the entire experimental period (<i>P</i> < 0.001), and had a higher proportion of internal fat than the LCS bulls. It can be concluded that purebred CH bulls were superior to the other breed groups in most of the traits observed. The intensive diet based on maize silage increased average daily gains, reduced the time needed to achieve the target slaughter weight, and improved the feed efficiency of bulls.

Zinc Bacitracin

SUMMARYThree experiments were carried out to evaluate zinc bacitracin as compared with penicillin, as a feed supplement for bacon pigs. The first experiment compared pig performance on a control diet with performance on the control diet supplemented with penicillin, 5 g./ton, or with zinc bacitracin, 10 g./ton. Experiment 2 compared the control diet with penicillin at 10 g./ton and zinc bacitracin at 10 g./ton with pigs housed in a different piggery. Experiment 3 compared the control diet with penicillin at 10 g./ton and zinc bacitracin at two levels, 10 g./ton and 5 g./ton. In none of the experiments was there any significant response to penicillin in terms of rate of gain, feed conversion efficiency or carcass composition. In the first experiment there was a small but significant improvement in rate of gain up to 100 lb. live-weight and for the whole experimental period by the pigs receiving 10 g./ton of zinc bacitracin. There was no significant response in feed conversion efficiency or carcass measurements. In the other two experiments there was no response to zinc bacitracin. The implications of the results are discussed.

Coconut Meal

Coconut meal (CM) was included in a broiler diet to supply 40% of the total groundnut cake protein. The diet was formulated based on the recommendations of a previous study that coconut meal protein can replace 40% of groundnut cake (GNC) in broilers diet. A control diet was formulated containing 22% GNC, the protein of which was replaced by coconut meal protein. Five diets were prepared . The control (Diet A) and 4 others that contained essentially the same proximate composition (Diets B-E) were supplemented with synthetic lysine at 0.30, 0,60, 0.90 and 1.20% dietary levels. 240 broiler chicks were alotted into 5 dietary treatment groups of 3 sub-groupa. Each sub-group contained 16 birds. The dietary lysine content from diets A-E were 1.20, 1.15, 1.45, 1.76 and 2.00% respectively and were fed to the broilers for a period of 56 days. Performance indices, average feed consumption, average body gain, live weight, feed conversion ratio (FCR), protein efficiency ratio (PER) were monitored. The dry matter, protein and ether extractretentions were all equally monitored twice at the 4th and 8th week. Haematological and enzyme assays were investigated  at 4th and 8th week. The average feed consumption and FCR were significantly increased (P<0.05) by the increasing level of lysine supplementation both at the 4th and 8th week. The body gain also decreased significantly (P<0.05) at the 4th and 8th week while the live weight was significantly (P<0.05) better in the control and 0.6% lysine supplementation at the 56th day of the study. The dry matter, nitrogen and other extract retentions significantly decreased (P<0.05) at the 4th and 8th week. The total protein and albumin decreased significantly (P<0.05) at the 4th and 8th week while, creatinine and urea increased with increasing level of lysine supplementation. The serum glutamate amino transaminase and alanine amino transaminase both increased significantly (P<0.05) at the 4th and 8th week. The study indicated that 0.6% lysine supplementation (of diet containing coconut meal contributing 40% protein of the major vegetable protein source) enhance the utilization of the coconut meal by broilers.

ABSTRACT: This study was conducted to assess the use of propolis ethanolic extract as an alternative to performance-enhancing antibiotics for piglets. Seventy piglets weaned at 21 days of age, with initial weights of 7.3±0.4kg and final weights of 24.9±1.2kg, were randomly assigned to five diets: positive control (diet with 200ppm antibiotic); negative control (diet without growth promoter); and diets with 100, 500, and 1,000ppm of brown propolis ethanolic extract, with seven replicates of two piglets each. The duration of the experimental period was 35 days. The diets did not influence (P>0.05) daily feed intake, daily weight gain, final weight, and feed conversion of animals. The bacteriological profile of the nasal swab presented a predominance of gram-positive bacteria commonly associated with the mucous membranes in all samples. Rectal swabs did not present atypical bacterial isolates. The use of ethanolic propolis extract in diets did not alter the performance of weaned piglets, nor did it affect the bacteriological profile, fecal score, or the occurrence of diarrhea in piglets.
