AbstractSensor feeding is a liquid feeding system for fattening pigs that is operated with a restricted animal/feeding-place ratio (AFR). The aim of the present study was to quantify the effect of three different AFRs (4:1, 7:1 and 13:1, calculated with a feeding space of 33 cm per animal) on the performance and behaviour of fattening pigs (mean initial weight 26·3 (s.d. 3·3) kg, live weight at slaughter 102 (s.d. 5) kg). The pigs were housed in groups of 40 and each AFR was tested with seven groups (21 groups in total). The daily weight gain of the individual pigs was calculated from the beginning of the experiments until slaughter. Additionally, the lean meat percentage was recorded (AutoFOM). Feeding behaviour was observed by means of 24-h video recording at the ages of 14 and 17 weeks with scan sampling every 5 min. The daily weight gain decreased with increasing AFR (P<0·01) and females had lower weight gains than barrows (P<0·001). The lean meat proportion was influenced by the AFR (P<0·01) and sex of the pigs (P<0·001). Proportions were highest with the AFR 13:1 and in females. The average number of pigs feeding simultaneously was highest for the AFR of 4:1 (P<0·01). Moreover, the ingestion rate per day (kg/min) increased with increasing AFR (P<0·05). The average number of pigs waiting behind other pigs feeding at the trough was highest with the AFR 13:1 (P<0·001).In conclusion, growth performance and pig behaviour were negatively affected by an AFR of 13:1, which cannot be recommended for use with this feeding system. With an AFR of 4:1 lean meat values were low.

Abstract This study aimed to determine the effects of increasing Methionine (Met) supply on growth performance and carcass traits of growing-finishing pigs under summer conditions in Brazil. A total of 200 barrows and females, 63 d-old (20.43±2.0 kg), were allocated in a 2 x 2 factorial design (two Met sources [DL-Met and OH-Met] and two Met doses [100 and 120% Brazilian Nutritional recommendation) with 10 replicates of 5 animals each. Corn-DDGS-wheat-soya based diets were formulated. Treatments were offered during four phases: growing I (63-93 d old), growing II (94-114 d old), finishing I (115-142 d old) and finishing II (143-160 d old). The recommended digestible Met levels were: 0.32, 0.30, 0.29 and 0.24% respectively for the four phases. Average temperature was 27.12 ± 4.51ºC and relative humidity was 61.72 ± 5.65%. Growth performance was measured for each rearing phase. Carcass yield, back fat height, loin depth, and lean meat yield were measured at the end of the experiment. Data were submitted to a 2-way ANOVA and Tukey test. There was no significant interaction between the Met source and the dose for all performance and carcass traits. Feed intake and feed conversion ratio were similar between treatments (P &gt;0.05). The individual daily weight gain and live weight were better for the highest doses of methionine (P&lt; 0.05) in all phases and on the whole period, except for the finishing II where the weight gain was similar for all treatments. Likewise, carcass yield, lean meat was increased with the highest dose of methionine in comparison to the adequate dose. No significant difference was found between DL-Met and OH-Met on growth performance parameters. OH-Met resulted in a higher loin depth (58.37 mm) in comparison to DL-Met (55.21 mm). Overall, these results demonstrated the interest of increasing Met supply under hot conditions to improving performance and carcass quality traits.

The objective of the current study was to examine the effects of mannan-oligosaccharides or inulin on HF dairy heifers’ starter feed intake and daily weight gain in farm situations. We measured these parameters across two experiments. In Trial 1 (T1), next to the control group, 15-15 HF heifers received MOS or inulin supplementation from 1st day of age to weaning. The amount of the supplementations changed according the calves’ age and the amount of milk replacer from 12 g to 24 g/calf/day. We measured the individual feed intake daily, the live weight at 0, 14, 21 and 60 days. In the second experiment (T2) we used 30 HF heifers also in three group (Control, MOS, Inulin) but we gave more from the experiment materials (28 g/calf/day MOS or Inulin). We started dosing the supplements with the colostrums feeding, and gave up on 14th day of age. We also measured the individual feed intake daily and the live body weight (BW) at 0, 14, 28, 42 and 56 days. The treatments in T1 did not cause significant differences in average feed intake, body weight and average daily weight gain. When the calves got the supplementation with colostrum too, the ADWG was significant lower in the group fed inulin than control and group fed MOS (P<0.05). We calculate the ADWG all of the experimental periods. From 0 to 14 day, and from 0 to 56 day the ADWG in inulin group was lower than control group, but the datas of group MOS did not differ from the others. Due to the distribution of the birth weights, the lower ADWG did not manifest in differences in body weight in other points of the experiments. We did not find an interaction between the treatments and the daily feed intake of calves. According with our measurements,

The Impact

The acceptance of eco-friendly black soldier fly larvae meal (BSFLM) as sustainable alternative protein ingredient in poultry feeds continues to gain momentum worldwide. This study evaluates the impact of BSFLM in layer chick and grower diets on the growth, carcass quality and economic returns. Mean weekly weight gain and total live weight per chick and grower varied significantly. The highest final weight gain was achieved when birds were provided diet with 25.6% BSFLM. Average daily feed intake (ADFI), average daily weight gain (ADG) and overall weight gain of the chick varied significantly, except for the feed conversion ratio (FCR). For grower birds, ADFI, ADG, FCR and overall weight gain did not vary significantly across the various feeding regimes. The weight of the wings and drumsticks had a quadratic response with a maximum weight obtained at 33% inclusion of BSFLM. The weight of the internal organs were not significantly affected by dietary types. Positive cost–benefit ratio and return on investment was recorded for diet types with higher BSFLM inclusion levels (>75%). Diets with 25% and 100% BSFLM inclusion were the most suitable and cost-effective, respectively. Thus, BSFLM represents a promising alternative source of protein that could be sustainably used in the poultry industries.

This work was carried out to evaluate the effect of supplements based on non-protein nitrogen (NPN) as: urea, amirea and multinutritional block, on live weight gain and cost analysis for cattle kept in pastures. During a period of 104 days(April to July 2004), 40 crossbreed bulls, uncastrated and initial average weight of 379kg, were allocated into 4 paddocks with Brachiaria brizantha cv. Marandu, in continuous pasture system receiving, in troughs, the following treatments: mineral salt (control), protein supplement containing amirea, protein supplement containing urea and multinutritional block. The experimental design used was randomized blocks with repetition within the block. Results of availability bromatological composition of pasture, supplement consumption and daily weight gain of animals were evaluated in two experimental sub-periods: 0 to 45 and 45 to 90 days. In the first sub-period, there was no effect of treatments (P>0.05) on daily weight gain but in the second sub-period, the multinutritional block showed smaller (P<0.05) weight gain than the ones which were similar among themselves, being: 0.60; 0.59; 0.61 and 0.22kg/animal/day, respectively, for the treatments with mineral salt, amirea, urea and multinutritional block. Before these edafoclimatic conditions, the period and duration of the experiment, the supplementation with mineral salt provided the higher profit.

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.

Young Cattle

The protein, vitamin and mineral supplements have been developed and it was studied the efficiency of feeding with them the young cattle in the composition of the grain production. The scientific and farm experiment has been carried out during 62 days. The study was conducted in four groups of bulls with 12 heads in each. The initial live weight at the beginning of the study was about 300–310 kg. Differences in feeding were in the fact that the grain forage for young animals of group I included PVMS No. 1, II – PVMS No. 2, III –PVMS No.3, IV – PVMS No 4. The grain feed is represented mainly by barley. The protein, vitamin and mineral supplement replenished 20 % of the deficient protein. It was discovered that concentration of hydrogen ions was practically at the same level in the rumen contents of steers of different groups. As for level of ammonia, VFA, total nitrogen, ciliates in the young cattle of I, II and III groups, the differences were insignificant. The concentration of ammonia of group IVcompared to I, II and III group was higher by 15.58, 23.61 and 21.9 %, VFA – by 6.7, 19.4 and 11.1 %, total nitrogen – by 3.32, 31.44 and 24.03 %, ciliates – by 4.35, 14.29 and 9.09 %, respectively. The research results showed that digestibility of protein, fiber and BEV was higher in the fourth group by 1–7 % compared with the rest groups (P>0.05). A slight increase in nitrogen deposition was found in IV group of young animals (by 4.7–11.9 %) receiving PVMS with AFA as a source of protein. The use of calcium and phosphorus by animals was almost at the same level. The research helped to determine that the average daily weight gain of animals of all the groups was within the range 629–710 g. The highest was in the fourth group consuming PVMS No. 4 with AFA as a protein component; the second place in terms is occupied by group I – 660 g, consuming PVMS No. 2, which included lupine, AFA and standard DKMK No. 1; PVMS No. 3 with depleted phosphate used as a source of phosphorus, took the last place in terms of this indicator – 629 g. Feed cost per 1 kg of weight gain was the lowest in IV group – 8.77 feed units, in I, II and III groups, it was higher by 8.32 %; 13.68 and 10.83 %, respectively. The cost of sold products from one animal during experiment turned out to be higher for steers that received PVMS No. 4 as compared to I, II and III groups by 6.82, 11.36 and 9.1 %, respectively.

Fattening Pigs

Abstract. Fattening pigs are commonly kept in intensive housing systems with slatted floor which represent a very barren environment, causing poor animal welfare. To improve such conditions a small amount of straw or hay (100 g per animal per day laid daily in a rack) was used in our study as an environmental enrichment (EE). Two replications, each including 96 fattening pigs of both sexes (3 pens of 16 females and 3 pens of 16 male castrates) from 60 kg to slaughter at average 96 kg live weight, were used to test the effect of EE and sex on behaviour, growth rate, and carcass composition. EE significantly increased the proportion of total activity during the illumination period (between 6 a. m. and 2 p. m.) on account of increased occupation with substrate (P<0.01). EE also significantly reduced time spent biting pen bars and frequency of aggressive encounters (P<0.01). The EE increased total activity in female animals during the observation period, but not in male castrates. None of the EE significantly influenced pigs‘ growth rate and lean meat percentage; however females in enriched environment grew slower and had greater lean meat percentage than the castrated males. Provision of a small amount of straw or hay to pigs in intensive housing systems can enrich barren environment in inexpensive and efficient way. Therefore such enrichment can be widely used also in large commercial pig production systems.

Six comparable groups, each of 4 castrate pigs, were used to compare the feed value of maize and sorghum as estimated by live-weight gain, food conversion efficiency, slaughter quality and ham composition.The maize ration contained 40% yellow maize and the sorghum ration 40% Sorghum vulgare subglabrescens, all other ingredients being the same for both diets.No statistically significant differences were found between the maize and sorghum pigs with regard to the criteria mentioned.It is concluded that no difference exists between the feed value of the maize and the sorghum used. This result is in better agreement with the net energy values of maize and sorghum as calculated by the formula of Hoff-mann and digestion coefficients for pigs, than with “classical” starch equivalents.
