Effect Of Feeding

The effect of feeding corn-soybean meal-based diets with two levels of supplemental leucine (0 vs. 2%) on growth, carcass, and pork quality characteristics was evaluated in 40 individually fed finishing pigs over a 39-d feeding period (78.4 ± 3.46 to 114.8 ± 7.30 kg liveweight). Supplemental dietary leucine reduced weight gain (8.7%; P < 0.05), but had no effect (P > 0.05) on feed intake or gain:feed ratio. Feeding diets with 2% supplemental leucine increased (P < 0.05) longissimus fat content and marbling scores in both barrows and gilts. Key words: Finishing pigs, dietary leucine, intramuscular fat

Finishing Pigs

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

Sixty 12-wk-old pigs were fed a corn–barley–soybean type diet in a 2 × 5 factorial experiment. Two mycotoxin, corn-based premixes were added: one with and without deoxynivalenol (DON) supplement (2.5 mg kg−1 feed) and the other with T-2 toxin at levels of 0.0, 0.4, 0.8, 1.6 and 3.2 mg kg−1 feed. After a 5-wk feeding period the pigs were killed; major organs were examined grossly and microscopically, and blood and tissue samples were taken for biochemical and hematological analyses. Lower final body weight and daily gain appeared (P > 0.05) to be associated with increasing dietary T-2 toxin content. Feed intake followed a similar trend. The performance of pigs fed the DON-supplemented diets was significantly less than for diets without the DON. There was an interaction between DON and T-2 toxin, with differences in weight gain and feed intake, at the two levels of DON, being smaller at the intermediate levels of T-2 toxin. The incidence of lesions on the mucosa of the pars esophageal region increased with increasing levels of T-2. Otherwise, there was little evidence that T-2 affected any of the major organs examined at necropsy or the biochemical and hematological criteria. It seemed that any effects detected were attributable more to DON and its interaction with T-2 than to the presence of T-2 toxin alone. Key words: Pigs, T-2 toxin, DON, toxin interaction

Thirty dairy heifer calves were reared from birth to calving on rations containing 0, 6.8 or 13.7% rapeseed meal in substitution for soybean meal. The level of rapeseed meal did not significantly (P > 0.05) affect feed intake, weight gain or feed efficiency of heifers up to breeding weight (330–340 kg). The level of rapeseed meal did not significantly (P > 0.05) affect reproduction or milk production during the first lactation. However, there may have been a trend for lower conception rate and milk fat production during first lactation with the higher level of rapeseed meal.

Abstract In the United States, bioethanol is generated from corn and biodiesel from soybean oil to reduce the dependence on fossil fuels. Ethanol production generates DDGS, high in bypass protein and soluble carbohydrates, which can be used as a cheaper alternative replacement for corn and soybean. This experiment was conducted to evaluate voluntary feed intake, body weight gain and blood metabolites of lambs fed legume-based diets supplemented with corn and soybean meal or dried distillers grain with solubles (DDGS). Animals were individually housed in pens (1.52 mx 1.52 m) under a modified carport shed with woodchips as bedding. They were stratified into four groups (n = 9) with similar weights and standard deviation and randomly assigned to four treatments. The lambs were fed ground sericea hay (SL) or alfalfa meal (ALF) with either corn and soybean meal (control) or DDGS for 60 days. Treatments were SLC, SLDDGS, ALFC and AFLDDGS. The lambs were fed ad libitum based on their selected treatment and given water daily. At the end of the 60 days, weights and blood samples were collected. Plasma samples were analyzed for blood urea nitrogen (BUN), glucose and non-esterified fatty acids (NEFA). Data were analyzed using Proc Mix Procedure of SAS. Results indicated that replacing corn with DDGS did not (P &gt; 0.05) affect voluntary feed intake, final live weight and carcass weight. Blood NEFA and glucose were not affected by dietary treatments. BUN increased in lambs fed alfalfa with corn and soybean meal compared to animals fed either legume supplemented with DDGS. Similarly animals fed sericea have lower (P &lt; 0.05) BUN (19 vs 23 mg/dL) when corn and soybean meal were replaced with DDGS. DDGS can be used in legume diets for growing lambs in replacement for corn and soybean meal.

Red Grape

The disposal of red grape pomace (GP) in landfills and by incineration has negative impacts on the environment. It is, therefore, imperative that alternative and sustainable ways of managing this waste product are identified. Using GP as a source of nutrients and beneficial bioactive compounds in avian diets is a potential waste-reduction and valorization strategy that promotes sustainable agriculture. However, there is limited information on the valorization of GP for this purpose. This study, therefore, investigated the effect of dietary inclusion of GP on growth performance, blood parameters, carcass characteristics, and breast meat quality traits of broilers. Four hundred, two-week old Cobb 500 broilers (279.2 ± 18.87 g) were allocated to 40 pens. Five isonitrogenous and isoenergetic diets were formulated by including GP in commercial broiler diets at 0 (GP0), 2.5 (GP25), 4.5 (GP45); 5.5% (GP55); and 7.5% (GP75). Feed intake, weight gain, feed utilization efficiency, hematology, serum biochemistry, carcass characteristics, and breast meat quality traits were measured. Chickens on GP75 had the least feed intake (p < 0.05) but there were no dietary effects on weight gain. Birds on GP0 had the highest (p < 0.05) feed conversion ratio (1.79) while those fed GP75 had the lowest (p < 0.05) ratio (1.45). Breast meat from broilers offered GP75 had the highest (p < 0.05) redness value (0.75) while the GP0 diet promoted the least (p < 0.05) redness value (0.49). Broilers fed GP55 and GP75 diets had higher (p < 0.05) feed conversion efficiency compared to GP0 birds. Inclusion of GP in broiler diets has the potential to reduce feed costs, thus making this valorization strategy a sustainable alternative to current pomace disposal methods. Adoption of this waste-reduction and valorization strategy promotes sustainable agriculture by contributing to food security and environmental stewardship.

Effect Of Feeding

Feding different physical forms of diets on performance and carcass traits of goats was studied. Thirty-six wethers were fed total mixed diets of either whole or rolled barley mixed with grass-alfalfa hay either chopped to 2.5 or 5 cm lengths. No differences (P > 0.05) in ADG (76.6 to 84.8 g d-1), feed intake (0.92 to 1.01 kg d-1), F:G (12.2 to 13.1 kg kg-1), hot carcass weight (13.5 to 14.1 kg), dressing %, (45.0 to 45.7%) and ribeye area (10.9 to 13.1 cm2) were observed among goats fed the four dietary combinations.
