The optimised use of mixed crude glycerin (MCG) and ractopamine hydrochloride (RH) in diets for finishing pigs requires a better understanding of glycerol metabolism. Therefore, the present study evaluated the performance, blood parameters, metabolite concentrations in the Longissimus lumborum muscle and the activity of enzymes in the liver, subcutaneous adipose tissue and kidney of pigs fed diets containing MCG and/or RH. According to the initial weight, 64 barrows were distributed in a 4 × 2 factorial design, corresponding to four concentrations of MCG (0, 100, 150, and 200 g/kg) in diets containing 0 or 10 mg/kg of RH. There was no MCG × RH interaction for any of the evaluated parameters (P > 0.05). Moreover, there was no isolated effect of dietary MCG or RH on the weight gain and the blood concentrations of glucose, insulin, triacylglycerols, total cholesterol, total protein, albumin, creatinine, cortisol and lactate (P > 0.05). There was a higher rate of phosphorylation of glycerol in the liver, stimulation of lipogenesis in adipose tissue and a likely increase in the utilisation of glycerol by muscle fibres in response to an increased concentration of circulating glycerol from the diet (P < 0.05). In contrast, when the diet contained up to 200 g/kg MCG and 10 mg/kg RH, there were indications of a lower utilisation of glycerol for the synthesis of triacylglycerols in muscle, liver and adipose tissue, in addition to increased oxidation of amino acids in the liver followed by improved feed conversion of pigs (P < 0.05).

Crossbred Pigs

A total of 192 Iberian × Duroc pigs kept under intensive conditions were used to investigate the effects of feeding crude glycerin on growth performance, nutrient digestibility, and blood parameters. Animals were blocked by initial body weight (96.0 ± 11.3 kg) and allotted to pens (16 pigs per pen). Pens were assigned randomly to one of three dietary treatments (four pens per treatment). Dietary treatments contained 0, 5, or 10% of crude glycerin proportionally substituting for wheat (G0, G5, and G10, respectively). Diets were formulated to be isoenergetic and isoaminoacidic. No significant effect of crude glycerin was observed on average daily gain, average feed intake, or feed conversion ratio. The apparent total tract digestibility of dry matter, organic matter, and crude protein was no different between treatments. Total serum protein, albumin, glucose, insulin, and IGF-1 were not affected by glycerin inclusion. In conclusion, crude glycerin up to 100 g/kg can be included in the diets of finishing Iberian crossbred pigs without any negative effect on growth performance, digestibility, or serum metabolic parameters.

Dairy Bulls

We assessed the productive performance, blood parameters, and carcass characteristics of young crossbreed dairy bulls kept in feedlots and fed with diets containing 0, 60, 120, and 240 g/kg of crude glycerin, replacing a mixture of ground pearl millet grain (50%) and babassu mesocarp bran (50%). Twenty-four bulls with an average age of 24 months and an average initial weight of 390 ± 31.5 kg were used. The experimental design was completely randomised with six replications. Dry matter and digestible energy intake were not influenced by diets. Feed conversion linearly decreased with increasing glycerin levels. The increase in the levels of glycerin resulted in a linear increase in blood glucose and in average daily weight gain. Carcass weight was not affected, but trimming fat increased and carcass yield decreased linearly, with increasing glycerin levels. The addition of crude glycerin at levels up to 240 g/kg of dry matter to diets containing babassu mesocarp bran and ground pearl millet grain increased the performance of young feedlot bulls, and improved feed efficiency and carcass subcutaneous fat thickness.

One hundred and twenty-four feeder pigs, representing two breed groups (Hampshire × Yorkshire and Yorkshire) were used in three experiments to compare the live performance and carcass characteristics of boars, barrows and gilts fed, from 25 to 92 kg, a 16% protein, barley–soybean meal diet or diets based on a utility grade, soft wheat (Triticum aestivum cv. Pitic 62) with 0, 7½ and 15% field peas (Pisum sativum cv. Century) to provide total protein levels of 13, 14 or 15%. Under conditions of adequate nutrition, boars were superior to barrows in efficiency of feed conversion and estimates of carcass leanness, while gilts were intermediate in feed conversion and equivalent to boars in carcass indices. The amount and composition of the diet consumed had a greater effect upon the relative performance of boars and, to a lesser extent, of gilts than was observed with barrows. In addition, the dressing percentage was consistently lower with boars than with barrows or gilts. Sexual odor or taint was not noticeably present in the carcasses at the packing plant, although there was a tendency for meat from boars on restricted feeding to have a higher moisture and darker lean than that present in carcasses from barrows and gilts. The results also suggested that satisfactory performance of growing–finishing pigs could be achieved with diets based on Pitic 62 wheat using field peas as the sole source of supplementary protein.

It is well established that the fatty acid combustion of adipose issue in pigs (non-ruminants) may be manipulated by changes in the fatty acid profile of the diets. The objective of this program of work was to quantify the responses of adipose depots of finishing pigs to changes in the level and profile of dietary fatty acids and to relate these changes to the sensory quality of meat as determined by taste panel.

Performance Trial

This study aimed to evaluate the use of silage of forage cactus (Opuntia ficus-indica Mill) in diets for finishing pigs. Two experiments were conducted: the first for digestibility and the second for performance. In the performance trial, the quantitative levels of feed restriction (0%, 10%, 20%, and 30%) were evaluated, which were associated with the supply of forage cactus silage. Forage cactus silage presented 2463.59 and 2456 kcal/kg of digestible and metabolizable energy, respectively. The feed restriction levels associated with the supply of forage cactus silage influenced feed intake, weight gain and final weight negatively, but did not affect feed conversion. Carcass absolute weight was influenced negatively. However, the yield of carcass and cuts and the amount of meat in the carcass were not influenced. With the increase in feed restriction, there was a decrease in duodenal mucosa thickness, intestinal glands, liver glycogen storage and the occurrence of inflammation in the submucosa and intestinal mucosa. Forage cactus silage is not accepted well by animals. The restriction up to 30% of balanced feed did not affect feed conversion, yield of carcass and cuts and economic viability. However, levels over 10% affected intestinal health.Keywords: Alternative feed, feed preservation, intestinal health, Opuntia ficus-indica Mill, pig nutrition

Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of five treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl-1, and from 1.70 to 3.25 g dl-1) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl-1 vs. 92.6 and 149.9 mg dl-1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

It was aimed to evaluate anti-GnRH vaccine efficiency on productive characteristics, seminal performance, size, and histology of testicles of lambs submitted to immunocastration. Twenty contemporary Texel lambs were evaluated, being 10 animals received two doses of 1 mL of anti-GnRH vaccine and 10 received two doses of 1 mL of saline, with an interval of 30 days. Seminal characteristics, weight and histological cut for the testicles, productive performance, and blood parameters were analyzed. Andrological monitoring was carried out every 30 days. All animals were kept on pasture of Urochloa spp. receiving daily supplementation protein-energetic by 90 days. There was effect of immunocastration on slaughter weight (44.3 vs. 48.3 kg), total gain (9.9 vs. 10.3 kg), daily gain (104.5 vs. 108.9 g/day), and feed conversion (5.83 vs. 5.97) respectively to immunocastrated and intact lambs. There was immunocastration effect on testicle weight (0.09 vs. 0.35 g), motility (4.5 vs. 61.0%), vigor (0.40 vs. 3.00), volume (0.09 vs. 0.74 mL) and swirling (0.20 vs. 2.70) in the third semen collection. Immunocastration through two doses of 1 mL of anti-GnRH vaccine with a 30-day interval between doses, causes infertility in sheep and can be adopted for lambs.

Two experiments were carried out with the objective of evaluating the performance and carcass traits of growing and finishing pigs fed rations with sticky coffee hull silage. In experiment 1, the coffee hulls were ground through a 4-mm screen and ensiled with 30% water and enzymatic-bacterial inoculant and evaluated in digestibility trial with 15 crossbred pigs distributed in a completely randomised design. Overall, the ensiling process did not improve the digestibility of the sticky coffee hulls. In experiment 2, it was used 60 pigs (32.52 to 59.58 kg) in the growing phase and 55 pigs (61.70 to 90.27 kg) in the finishing phase, distributed in a completely randomised design with five diets (0, 4, 8, 12 and 16% of sticky coffee hull silage) and six replicates. In the growing and finishing phase, inclusion of levels of sticky coffee hull silage did not affect feed intake, weight gain, and plasma urea nitrogen. However, in the finishing phase, feed conversion improved as the levels of sticky coffee hull silage increased. Responses by backfat thickness and marbling were quadratic, whereas empty stomach weight increased linearly when sticky coffee hull silage was included in the diet. Sticky coffee hull silage has good nutritional value and if used in levels up to 16% of the diet, it does not impair performance of pigs in the growing and finishing phases and it results in leaner carcasses. However, the economic feasibility of its use depends on the price relationship of this by-product with the other feedstuffs.
