Enhancing feed efficiency in converting feed mass into pig body mass is a critical phase for the profit in producing pig. To improve the metabolic utilization of dietary nutrients, it relies heavily on a healthy gut or gastrointestinal tract, and only a healthy digestive can result in better feed digestion and better nutrient absorption. Thus, the study investigates the growth performance, the response of the digestive morphology of native pigs, which treatment will stretch higher output and variations under different levels of fermented mungbean. The experimental research design was employed to determine the response of the three (3) pigs treated with mungbean for 70 days. The growth performance of pigs treated with different levels of fermented mungbean has a total gain weight of 7.50kg for Treatment 1; Treatment 2 is 9.00kg and, Treatment 3 is 6.50kg and is observed no significant difference on the final weight and the total weight with a p-value of > 0. 050; the response on digestive morphology such as small intestine, large intestine, heart, stomach, liver, lungs, esophagus, spleen, and kidney of pigs shows no variations on their length, width, and weight with a p-value of >0.050 under the different level of fermented mungbean; and resulted with high output treated with different level of fermented mungbean is observed on Treatment 2 with a lowest feed conversion efficiency of 3.89 for feeds and 1.39 for mungbean. Treatment 2 has the highest gain weight among the treated sample; the intestinal morphology of pigs was comparable under the three treatments; treatment 2 has the lowest feed conversion efficiency.

Plasma Triiodothyronine

The aim of the present study was to investigate the effects of induction hypothyroidism by propylthiouracil (PTU) on the growth performance and meat quality of fat-tailed Lori-Bakhtiari lambs. Eighteen Lori-Bakhtiari male lambs were randomly assigned to one of three groups (n = 6) and received daily treatments (gavage) consisting of 0 (Control: C), 10 (Low: L) or 20 (High: H) mg PTU/kg bodyweight/day for 60 days. PTU decreased plasma triiodothyronine and thyroxine concentration in both L and H (P < 0.0001). Lambs treated with PTU (L and H) had lower feed intake (P < 0.004), feed conversion efficiency (P < 0.003), and greater intramuscular fat than C lambs (P < 0.035). Meat from the L and H lambs had lower cooking loss and shear force, and also higher L* (lightness) than C lambs (P < 0.004, P < 0.015 and P < 0.025, respectively). The meat of H and L lambs was more tender than C lambs (P < 0.032). However, the meat of H lambs required fewer chews before swallowing than C lambs (P < 0.041). Generally, induction of mild hypothyroidism appeared to improve feed conversion efficiency and meat quality of lambs.

Selection For

Thirty-five steers and 37 heifers were grown at pasture and finished in a feedlot to meet Australian domestic market specifications, i.e. 160-200 kg carcass weight with 5-9 mm subcutaneous fat at the P8 rump site. The animals were from lines that had been selected for either high growth rate to 600 days (UPWT) or for low rectal temperature under conditions of high ambient temperatures (TEMP) and from a control line (CONT). They were slaughtered in six groups at fortnightly intervals when liveweight of individuals was estimated to satisfy market requirements. Animals from the UPWT line were heavier at all ages than animals from the TEMP and CONT lines (P< 0.05) and had higher liveweight gains at pasture (P < 0.01). There was no difference between the lines in liveweight gains in the feedlot. At the same carcass weight, UPM animals had leaner carcasses (P < 0.01) but similar levels of marbling to CONT line animals. TEMP line animals were also leaner than CONT line animals (P < 0.0l ) , but had more marbling (P<0.01). There was no significant difference between lines in feed conversion efficiency. Steers were heavier (P < 0.001) than heifers at all ages, grew faster (P < 0.001) except during the immediate post-castration period, had higher feed intakes (P < 0.05) but better feed conversion efficiencies (P < 0.05), and at the same carcass weight were leaner (P < 0-01) and had less marbling (P < 0.05). Meat colour, cooking loss, ultimate pH and meat tenderness did not differ significantly between lines or sexes. These results are discussed with reference to the use of selection for growth or heat resistance to improve growth and carcass traits of beef herds in tropical areas.

Forty-eight crossbred wether lambs (38 kg) were randomly assigned to two dietary groups (LUC, chaffed lucerne ad libitum; CSM, LUC plus 300 g cottonseed meal/lday) and two hormone treatment groups (rGRF, recombinant growth hormone-releasing factor (GRF); sGRF, synthetic GRF) plus controls (CON, excipient only), and slaughtered after treatment for 28 (n = 36) or 30 (n = 12) days. An initial slaughter group (n = 12) was killed on day 0. CSM reduced intake of lucerne chaff, but increased total feed intake. CSM also increased liveweight gain and wool growth, with no effect on feed conversion efficiency. CSM increased carcass weight and decreased subcutaneous fat depth, with no effect on dressing percentage or longissimus dorsi (LD) area. Meat tenderness tended to decrease with CSM supplementation. CSM increased carcass protein accretion ( P < 0.01), with no significant change in fat gain or final composition (P > 0.05). CSM increased weights of the pelt, liver and empty body, and decreased the proportion of digesta in liveweight. Weights of blood, forestomachs and small intestine tended to increase as well (P < 0.10). Both sources of GRF had similar effects. Intakes were not significantly affected by GRF, but feed conversion efficiency improved (P < 0.01) with GRF treatment (6.4 v. 9.2 feed:gain for GRF and CON respectively). Liveweight gains and final weights of the whole body and carcass were increased additively by CSM and GRF. GRF reduced fat depth and increased LD area, with no effect on dressing percentage, carcass length or meat tenderness. These changes reflected increased carcass protein and reduced fat contents, brought about by increased accretion of protein and water and reduced fat gain due to GRF. GRF increased weights of blood and liver beyond the general increase in body size. Cottonseed meal and GRF additively produced significant improvements in growth performance and carcass quality of young wether lambs fed a roughage diet. GRF may be a useful tool to improve livestock production under extensive and intensive conditions.

Feeding Diets

Two experiments were conducted, using a total of 288 crossbred boars, gilts and barrows from the progeny of two Yorkshire sow lines, one kept as control, and the other selected for lower backfat thickness and increased growth rate for six generations. The lysine to DE (g MJ−1) levels used during grower (20 to 60 kg) and finisher (60 to 105 kg) periods, respectively, in the three diets (14.2 MJ DE kg−1) were: 1) 0.53 and 0.42 with no other supplemental amino acids except lysine, 2) 0.69 and 0.57 with supplemental threonine and methionine at a ratio of 0.65 and 0.30 to dietary lysine and 3) 0.85 and 0.72 with supplemental threonine and methionine at similar ratios as in diet 2. Feeding diets 2 and 3 increased (P < 0.05) the ADG and feed conversion efficiency of all pigs in both experiments, and this response was mainly during the grower period. Feeding diet 3 improved the growth rate more than diet 2 only in boars and gilts but not barrows. It also increased the feed conversion efficiency in exp. 2. The increased feed conversion efficiency response was higher in select than control line pigs, and in boars. Feeding diets 2 and 3 also improved the carcass merit but reduced the meat quality with an increased firmness and reduced marbling, juiciness, and flavour. The overall results indicated that an average daily intake of approximately 17 g of lysine (0.74 g MJ−1 DE), 11 g of threonine and 5 g of methionine during the grower period and 25 g lysine (0.62 g MJ−1 DE), 18 g threonine and 8 g methionine during finisher period optimized the growth performance, lean growth rate and carcass merit. This response tended to be higher in select than control line, and in boars and gilts than barrows. Key words: Lysine, amino acids, energy, growth, carcass, pigs

Green Seaweed

Using seaweeds as sources of nutrients and beneficial bioactive compounds can promote sustainable production of functional poultry products. This study investigated the physiological and meat quality responses of Cobb 500 broiler chickens to graded levels of green seaweed (Ulva sp.) meal (SWM). Three hundred, two-week-old male chicks (159.3 ± 11.76 g live-weight) were randomly assigned to five diets formulated by diluting a standard broiler diet with SWM at 0 (SW0), 20 (SW20), 25 (SW25), 30 (SW30) and 35 g/kg (SW35). There were neither linear nor quadratic trends (p > 0.05) for overall feed intake, overall growth performance and carcass and meat quality traits. Overall feed conversion efficiency (R2 = 0.192, p = 0.018) and spleen weights (R2 = 0.182; p = 0.020) linearly declined as SWM levels increased. Linear and quadratic responses (p > 0.05) were observed for lymphocytes. There were linear effects for meat pH except on day 7 of storage. Meat lightness (L*) linearly increased whereas meat redness (a*) quadratically responded to SWM levels (day 3 of storage). While an optimum inclusion level could not be established for seaweed based on growth performance, improvements in some meat shelf life indicators were observed in the broilers reared on seaweed-containing diets.

This experiment was conducted in animal felid/ University of Baghdad/ College of Agriculture/ Animal production from 9/11/2016 until 9/1/2017. Twelve growing Awassi ewes lambs weighted 29.13 ±1.50 kg and 8-10 month old were used in this study, the lambs were divided into three individual groups (4 animals/ group) receive the dietary treatments contain 0.2 and 4% tallow, animals were fed concentrate at 2.5% of body weight, Alfalfa hay was given ad libitum basis as the roughage, The results found that: No significant difference between groups in total and daily concentrate, roughage and total feed intake, However, final body weight not affected by the experimental diets, total and daily weight gain had higher values (p<0.05) in diets containing 2 and 4% tallow, feed conversion efficiency improved significantly (P<0.05) in 4% tallow diet compared to other groups. It can be concluded that added tallow to sheep diets improved some productive performance such as total and daily weight gain, feed conversion efficiency. Excess animal fats from human consumption can be used as an energy source in ruminants feeds. Thus benefiting from excess animal fats from human consumption as a source of energy in ruminants' rations.

Maintenance Requirements

The experiment was conducted to study the effect of oats and barley in high-grain rations on performance of calves and on totals and proportions of muscle, bone and fat in the carcasses. Each experimental diet was fed to a group of four Jersey bull calves. There was no significant difference between the two groups of calves in average daily liveweight gain, and very little difference in feed conversion efficiency and daily feed consumption.On the basis of total dissection of one-half of each carcass, calves fed barley contained practically the same amount of lean, similar proportions of bone and more fat (23.6% vs. 14.9%) compared with those fed oats. Barley-fed animals consumed 26.3% more digestible energy over maintenance requirements than oats-fed animals. This resulted in 58.4% more dissectable fat in the carcasses of barley-fed animals.
