Fattening Pigs

Considering that our previous research has indicated some positive effects of probiotics used in nutrition of sows and suckling piglets, as well as piglets in rearing, investigation designed in this case had the objective to investigate the effect of introduction of probiotic Paciflora-C-10, based on Bacillus spp C.I.P. 5832 in nutrition of fattening pigs. Investigations were carried out on Experimental pig farm of the Institute for Animal Husbandry, Belgrade-Zemun. Crietria for evaluation of obtained results were production performance, degree of use of nutritious substances slaughter parameters and economical analysis determined as price of gain of 1 kg of body mass. It was established that introduction of probiotics has induced the increase of body mass gain by 3,88%, feed conversion by 2,81% degree of utilization of dry and organic matter as well as crude proteina in mixtures. Also, in regard to slaughter traits, it was established that use of probiotic had positive effect on dressing percentage. No effect on food consumption, meatiness in warm carcasses or price of body mass gain was determined on experimental animals.

Modern broiler production is based on exploitation of meat type hybrids which are characterized by intensive growth, excellent food efficiency, strong constitution and excellent body conformation. In Serbia, many foreign proveniences are present and therefore there is a need to define a hybrid which in existing production conditions would realize the best fattening results. Objective of the study was to determine the production results of two most present line hybrids on our market, Cobb-500 and Ross-308. The following production parameters: body mass, gain, feed consumption, feed conversion, mortality and production index were monitored. One day old chickens were distributed randomly in two groups with 4 repetitions per each hybrid. In nutrition of broilers complete pellet mixtures were used, which ensured that all broiler requirements in energy, proteins, mineral substances, vitamins and essential amino acids were met. Higher final body mass was realized by Ross-308. In regard to feed conversion, mortality, feed consumption and value of production index, it is observed that Cobb-500 broilers realized better feed conversion (1,78), lower mortality (7,00%), lower consumption of feed per chicken (4238g) and higher value of production index with 316 index points compared to Ross-308 (1.82; 9,00%; 4407g; 309). Obtained production indexes for both hybrids were very high, so it can be concluded that there are no statistically significant differences between these two hybrids. It can be concluded that achieved results are satisfactory, and that hybrids have high genetic potential.

Objective of this research was to investigate the effect of addition of enzyme complex to diets of different nutritive value on performance of broiler chickens. In this trial 1200 chickens of Cobb 500 hybrid divided into 4 treatments with 8 repetitions were used: 1. Positive control; 2. Positive control with addition of 0,02% of enzyme complex; 3. Negative control (contains 0,3 MJ of energy, 0,1% of accessible P and 0,1% Ca less compared to group 1); 4. Negative control with addition of 0,02% of enzyme complex. Application of enzyme preparation resulted in positive effects on gain and feed conversion, regardless if it was added to standard mixtures or mixtures of diminished nutritive value. Economical analysis of obtained results showed that improvement realized by application of enzyme preparation exceeds costs of its application.

Abstract We recently identified a novel hypothalamic small protein, named neurosecretory protein GL (NPGL), which is involved in energy homeostasis in birds and mammals. However, whether the action of NPGL is influenced by nutritional composition remains unknown. Thus, we investigated the effect of chronic intracerebroventricular infusion of NPGL for 13 days on feeding behavior and body mass gain under a normal chow diet (NC), high-fat diet, high-sucrose diet (HSD), and medium-fat/medium-sucrose diet (MFSD) in rats. NPGL stimulated food intake of NC and MFSD, especially during the light period. By contrast, NPGL decreased body mass gain under NC and increased total white adipose tissue mass in HSD- and MFSD-fed rats. These data suggest that the effects of NPGL on feeding behavior, body mass gain, and fat accumulation depend on nutrient type. Among them, sucrose in diets seems to contribute to fat accumulation elicited by NPGL.

We assessed the urinary indexes of hydration status of Greco-Roman wrestlers in an authentic precompetition situation at the time of official weigh-in (OWI). A total of 51 of 89 wrestlers competing in the Estonian Championship in 2009 donated a urine sample. Questionnaire responses revealed that 27 wrestlers (body mass losers (BMLs)) reduced body mass before the competition, whereas 24 wrestlers (those who do not lose body mass (n-BMLs)) did not. In 42 wrestlers, values of urine specific gravity ≥1.020 and urine osmolality ≥700 mOsmol·kg−1 revealed a hypohydrated status. The prevalence of hypohydration in the BMLs (96%) was higher than in the n-BMLs (67%) (χ2 = 7.68; p < 0.05). The prevalence of serious hypohydration (urine specific gravity >1.030) was 5.3 times greater (χ2 = 8.32; p < 0.05) in the BMLs than in the n-BMLs. In the BMLs, the extent of body mass gain during the 16-h recovery (2.5 ± 1.2 kg) was associated (r = 0.764; p < 0.05) with self-reported precompetition body mass loss (4.3 ± 2.0 kg) and exceeded the body mass gain observed in the n-BMLs (0.7 ± 1.2 kg; p < 0.05). We conclude that hypohydration is prevalent among Greco-Roman wrestlers at the time of OWI. The prevalence of hypohydration and serious hypohydration is especially high among wrestlers who are accustomed to reducing body mass before competition. These results suggest that an effective rehydration strategy is needed for Olympic-style wrestlers, and that changes in wrestling rules should be considered to reduce the prevalence of harmful body mass management behaviours.

This study aimed to investigate the effects of interval and continuous training on the body mass gain and adiposity levels of rats fed a high-fat diet. Forty-eight male Sprague-Dawley rats were randomly divided into two groups, standard diet and high-fat diet, and received their respective diets for a period of four weeks without exercise stimuli. After this period, the animals were randomly divided into six groups (n=8): control standard diet (CS), control high-fat diet (CH), continuous training standard diet (CTS), continuous training high-fat diet (CTH), interval training standard diet (ITS), and interval training high-fat diet (ITH). The interval and continuous training consisted of a swimming exercise performed over eight weeks. CH rats had greater body mass gain, sum of adipose tissues mass, and lower serum high density lipoprotein values than CS. The trained groups showed lower values of feed intake, caloric intake, body mass gain, and adiposity levels compared with the CH group. No significant differences were observed between the trained groups (CTS versus ITS and CTH versus ITH) on body mass gains and adiposity levels. In conclusion, both training methodologies were shown to be effective in controlling body mass gain and adiposity levels in high-fat diet fed rats.

In general, 3,5-diiodothyronine (3,5-T2) increases the resting metabolic rate and oxygen consumption, exerting short-term beneficial metabolic effects on rats subjected to a high-fat diet. Our aim was to evaluate the effects of chronic 3,5-T2 administration on the hypothalamus–pituitary–thyroid axis, body mass gain, adipose tissue mass, and body oxygen consumption in Wistar rats from 3 to 6 months of age. The rats were treated daily with 3,5-T2 (25, 50, or 75 μg/100 g body weight, s.c.) for 90 days between the ages of 3 and 6 months. The administration of 3,5-T2 suppressed thyroid function, reducing not only thyroid iodide uptake but also thyroperoxidase, NADPH oxidase 4 (NOX4), and thyroid type 1 iodothyronine deiodinase (D1 (DIO1)) activities and expression levels, whereas the expression of the TSH receptor and dual oxidase (DUOX) were increased. Serum TSH, 3,3′,5-triiodothyronine, and thyroxine were reduced in a 3,5-T2 dose-dependent manner, whereas oxygen consumption increased in these animals, indicating the direct action of 3,5-T2 on this physiological variable. Type 2 deiodinase activity increased in both the hypothalamus and the pituitary, and D1 activities in the liver and kidney were also increased in groups treated with 3,5-T2. Moreover, after 3 months of 3,5-T2 administration, body mass and retroperitoneal fat pad mass were significantly reduced, whereas the heart rate and mass were unchanged. Thus, 3,5-T2 acts as a direct stimulator of energy expenditure and reduces body mass gain; however, TSH suppression may develop secondary to 3,5-T2 administration.

AbstractQuantifying food intake in wild animals is crucial to many ecological and evolutionary questions, yet it can be very challenging, especially in the marine environment. Because foraging behavior can be inferred from dive recordings in many marine creatures, we hypothesized that specific behavioral dive variables can indicate food intake. To test this hypothesis, we attached time-depth recorders to breeding Adélie penguins also implanted with RFID tags that crossed a weighbridge as they traveled to and from the ocean to feed their chicks. The weighbridge reported how much mass the penguin had gained during a foraging trip. The variables that explained a significant amount of the change in body mass while at sea were the number of foraging dives per hour (46%) and the number of undulations per hour (12%). Most importantly, every increment of 1 in the rate of foraging dives per hour equated to a penguin gaining an average 170 g of mass, over the course of a 6–60 h foraging trip. These results add to a growing understanding that different metrics of foraging success are likely appropriate for different species, and that assessing the types and frequencies of dives using time-depth recorders can yield valuable insights.
