The aim of the work was to assess the effect of dietary inclusion of meals derived from black soldier fly (BSF) larvae on the performance and carcass composition in broilers. The trial was carried out with Ross 308 broilers divided in three groups according to the formulated diets: control, receiving standard diet, DFBSFM (receiving 5% partially defatted BSF meal), and FFBSFM (receiving 5% full fat BSF meal during the growing-finishing period, 14 to 35 days of age). The performance parameters controlled included body weight, weight gain, feed intake, feed conversion ratio, as well as the growth rate for each week of the trial. At 35 days of age, 10 broilers from each group were slaughtered and subjected to carcass analysis. The inclusion of 5% DFBSFM and FFBSFM in the diet improved performance of the broilers at the age of 21 and 35 days. The carcass weight and dressing percentage were higher in the groups receiving the insect meals. The results indicate potential of the DFBSFM and FFBSFM to alter the carcass composition of the broilers. Their inclusion in the diet of the birds tended to increase the percentage of the breast cuts, whereas the thigh muscles significantly decreased. The results of the study suggest good prospective for further research with the examined BSF meals, for their application as feed components in broiler nutrition that will not have adverse effect on the carcass composition and quality.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P < 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P < 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P < 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

Two experiments were conducted to examine the nutritive value of yellow lupins for weaner pigs. Using a completely randomised block design, Experiment 1 was conducted to determine the optimum inclusion level for yellow lupins (cv. Wodjil) in the diet of weaner pigs (6.14 kg ± 0.278). Experiment 2 was conducted using a 2 × 2 factorial design to examine whether supplementation of an enzyme preparation (VegPro) either in a soybean meal-based diet (0 g/kg yellow lupins) or in a yellow lupin-based diet (150 g/kg) improved performance of piglets (6.17 kg ± 0.317). In Experiment 1, the feed conversion ratio significantly increased at week 1 (linear effect, P = 0.040) and at week 3 (quadratic effect, P = 0.010) as the concentration of yellow lupins increased in the diet. In Experiment 2, supplementation with the enzyme preparation improved the feed conversion ratio in the pigs fed the lupin-based diet only but not in the pigs fed the soybean meal-based diet in week 2 (interaction P = 0.001). The results indicate that the optimum inclusion levels of yellow lupins for piglets immediately after weaning was 150 g/kg, and supplementation of a multi-enzyme preparation to a yellow lupin-based diet for the weaner pigs improved performance relative to the soybean meal-based diet.

Two experiments on the effect of dietary protein/energy ration on growth and carcass composition in Daldale wether lambs were carried out.In experiment 1, two groups of eight lambs in each group were fed in pens at a restricted intake (30 g air-dry feed per kg liveweight) either on a high protein/high energy diet (HP/HER) (20.7% crude protein) or on a low protein/high energy diet (LP/HER) (10.3% crude protein). The lambs were grown from 24.8 kg liveweight until slaughter at 37.5 kg. In experiment 2, two groups of eight lambs in each group were fed in pens a pelleted diet ad libitum, either on a high protein/high energy ration (HP/HEA) or on a low protein/high energy ratio (LP/HEA). The lambs were grown from 22.0 � 0.8 kg liveweight until slaughter at 37.5 kg. Those lambs on the HP/HE diets grew significantly faster than their counterparts on the LP/HE diets. Accordingly, animals given the HP/HE diets showed a superior feed conversion ratio than animals given the LP/HE diets. Despite these differences, there was no overall differences between treatments either at restricted or at ad libitum intake in the weight of carcass, the dressing percentage, and in the chemical composition of the carcass. In general, the carcasses produced contained a similar amount of fat (30.6%-32.9% of carcass). It was concluded that varying protein to energy ratio in diets affected liveweight gain and feed conversion ratio, but did not affect carcass composition.An experiment was conducted on the diets to investigate some aspects of digestion in the stomach and intestines at the two levels of crude protein.Dietary crude protein level had little effect upon the apparent digestibility of organic matter (OM) and neutral detergent fibre in the whole tract, the proportion of NDF digested in the stomach, the total volatile fatty acid concentration (VFA) in the rumen and the proportions of individual VFA.The flow of rates of digesta from the rumen and abomasum were also similar for the two diets. However, the proportion of the total digestion of OM occurring in the stomach decreased, while the flow of total N and crude protein (CP) (total N minus ammonia N x 6.25) to the intestines and the amounts of N and CP digested therein was higher on the HP diet.The data from the digestion experiment showed that the amount of digestible CP in the intestines per unit of digestible OM intake did not affect carcass composition.

This study was conducted to evaluate the nutritional value of potato tuber meal (PTM) for broiler chickens during growing (22–42 days) and finishing (43–49 days) periods. A total of 360 1-day-old male broiler chicks (Ross 308) were fed a corn-soybean meal-based diet until 21 days of age, then randomly assigned to six experimental diets, in which corn was replaced by PTM at 0%, 10%, 20%, 30%, 40%, and 50% levels by weight, respectively. Replacement of corn with 10%, 20%, 30% and 40% PTM had no effect on feed intake, bodyweight gain, and feed conversion ratio (P > 0.05). However, replacing 50% of corn with PTM resulted in a significant reduction (P < 0.05) in bodyweight gains from 22 to 42, and 22 to 49 days of age. Moreover, there was a significant (P < 0.05) increase in feed conversion ratio when 50% of corn was replaced by PTM. Corn replacement with PTM did not affect (P > 0.05) carcass and organ weights of broilers at 42 days of age. However, compared with the Control group, the relative length of the ileum was increased (P < 0.05) by inclusion of PTM in the diets, and it was statistically different for broiler fed diets in which 20% or 50% of corn was replaced by PTM. The serum concentrations of triglycerides, cholesterol, urea, and uric acid were not affected (P > 0.05) by diet inclusion of PTM. Replacing 50% of dietary corn with PTM significantly (P < 0.05) decreased apparent ileal digestibility of protein at 42 days of age. The excreta content of uric acid was not affected by diet inclusion of PTM. In conclusion, our results showed that PTM can replace dietary corn up to 40% during the growing and finishing periods with no adverse effects on growth performance of broiler chickens. Also, replacing up to 40% of corn with PTM in broiler diet had no adverse effect on carcass composition, blood constituents, and apparent ileal digestibility of protein at 42 days of age.

Abstract. The objective of this study was to determine the effects of breed and a diet containing linseed on the growth and carcass composition characteristics of heifers. A total of 48 Limousin (LI) and Charolais (CH) heifers with an average weight of 270 kg were assigned to two diets containing either extruded linseed (LIN) or no supplemental oilseed (CON). The target slaughter weight was set at 500 kg. The diet had no effect on any of the observed production traits. The CH heifers had higher live weight gains (P<0.001) and a lower feed conversion ratio (P<0.001). The LI heifers had a higher dressing percentage (P<0.001), higher meat to bone ratio (P<0.001), greater m. longissimus lumborum et thoracis area (P<0.05), and produced more internal and carcass fat (P<0.05). It was concluded that purebred LI heifers grew less rapidly and less efficiently but produced heavier carcasses with a more favourable meat to bone ratio compared to purebred CH heifers.

In this study, the possibility to control enzootic pneumonia by spraying mild organic acids in fatteners' buildings was investigated. In a farm with enzootic pneumonia, two groups, each of 120 weaned pigs, were housed in 2 separate rooms. With the pigs inside, the rooms were being sprayed once a week, for a total period of 20 weeks (up to the end of fattening period), either with a mixture of organic acids (1st room= AML-pigs), or with water (2nd room= placebo control pigs). Groups were compared with each other with respect to pigs' health status, mortality, performance parameters (average daily gain, feed conversion ratio) and the presence of specific lesions and pathogens in their lungs. It was shown that the incidence of coughing and the mortality in the AML-pigs were lower (10% and 3.25% respectively) compared to placebo controls (25% and 8.26% respectively). At the age of 70,120 and 165 days, the AML-pigs were 1.9 kg, 2.85 kg and 4.75 kg heavier, respectively, compared to controls (P< 0.001). Also, the pigs of the acid treated group have performed better than the controls with respect to average daily gain (674 g and 640 g respectively) and feed conversion ratio (3,00 and 3,14 respectively) (P<0.05). Lung lesions, characteristic for enzootic pneumonia, were detected in 37.5% of the AML-pigs and in 57.5% of placebo controls. Bacteria in the lungs, possibly complicating the disease, were isolated from more pigs of the control group compared to the acid-treated group. Finally, no clinical side effects following each application of the product were observed. The results of the present study show that, spraying of mild organic acids in a Mycoplasma hyopneumoniae-affected pig farm can be used for controlling the disease and improving performance parameters.

One hundred and twenty, one day old Anak breeds were randomly assigned to five treatment diets. Each group was replicated into four with six birds per replicate. Five experimental diets were formulated with diet 1 (T1) as control, contained 0% Goat Blood-Rumen Content Mixture (GBRCM) and aromatic plants. Diet 2 (T2) contains 10% GBRCM without aromatic plants supplementation. Diet 3, 4 and 5 (T3, T4 and T5) contained 10% goat blood-rumen content mixture supplemented with garlic (Allium sativum), ginger (Zingiber officinale) and rosemary (Rosemarinus officinalis). The experiment lasted for 56 days. Parameters evaluated were; body weight gain, feed intake, feed conversion ratio, protein intake, protein efficiency ratio, nutrient digestibility and economics of production. The results showed that birds fed with aromatic plant supplemented had significantly (P<0.05) higher body weight gain, feed intake and superior feed conversion ratio than birds fed with unsupplemented and control. There was no significant (P>0.05) difference on the parameters of the birds fed with control diet T1 and T2 among the treatments. Diet T3 formulated with 10% goat blood-rumen content and 5 grams of Allium sativum indicated the best performance followed by diet T4 and  diet T5 . This showed that the goat blood-rumen content based-diet supplemented with  aromatic reduced the high cost of feed material, ensured greater productivity and has no adverse effect on health status of the birds. The GBRCM based-diet supplemented in the broiler bird's diets reduced the cost of production with no adverse effect on performance.

This study was carried out to investigate the effects of pen colour and photoperiod interactions on the performance and respiratory rate of gilts at finisher stage. Thirty-six crossbred (Large white x Landrace) gilts of mean body weight of 38.12±0.59kg were randomly allotted to four (4) treatments. Pens were painted with different colours: pantone441 (control), pantone293 (blue), pantone185 (red) and pantone361 (green) and exposed to photoperiods of 12, 15 and 18 hours (h). The experimental design was 3x 4 factorial arrangement in a completely randomised design. Performance parameters measured were Feed Intake (FI), Final Weight (FW) and Weight Gain (WG), while Feed Conversion Ratio (FCR) was calculated weekly throughout the eight weeks of the experiment. Respiratory and rectal temperatures were also monitored. The main effect of pen colour was not significant (p>0.05) on FW and WG across the treatments while there were no significant variations (p>0.05) in the values of FI and FCR of the gilts due to pen colour. The respiratory rate varied significantly (p<0.05) with gilts in red pen (46.64±2.32) having the highest value. Photoperiod had no significant (p>0.05) effects on FW and WG, while FI and FCR had significant (p<0.05) variation across the treatments [12 h. (5.05±0.37),18 h(4.70±0.22) and 15 (4.68±0.25)]. Interactions of pen colour x photoperiods was also significant for FW, WG, FCR and FI. It can therefore be concluded that rearing gilts at finisher stage in green, blue or red pens gives optimal performance and photoperiod of 12hours gives maximum production.
