Forty-five Yorkshire baby pigs from five litters (9 pigs from each litter and with mean body weight 1.9kg), at two days of age were randomly, within litter, left with the sow to 21 days of age (treatment 1), weaned to a 24% protein dry diet fed ad libitum (treatment 2), or to homogenized cow milk fed in restricted amounts four times daily to 21 days of age (treatment 3). From day 22, all pigs were fed a corn-soybean meal type diet containing 18% protein to 10 weeks of age, and a similar diet containing 16% protein from 10 weeks of age to slaughter at approximately 160 days. Average daily weight gain (ADG) and live body weight at slaughter were significantly lower, and feed/gain significantly higher among cow milk-fed pigs (treatment 3) than among pigs left with the sow until 3 weeks (treatment 1) and pigs weaned to dry diet (treatment 2). Backfat thickness, loin eye area, yield of lean cuts and dressing percent did not differ significantly among treatments. The results confirmed that weaning at two to three days to a dry diet fed ad libitum or to cow milk fed in restricted amounts four times daily is feasible, but overall performance from birth to slaughter of pigs weaned to a dry diet at two days of age was similar to that of pigs weaned at three weeks of age and superior to that of pigs weaned to cow milk at two days of age.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

The purpose of the research is increasing the average daily gain of animals due to the use of the Bisolbi drug. The effect of Bisolbi preparation based on Bacillus subtilis H-13 1.5×108 (LLC «Bisolbi-Inter») on the biochemical and productive life of calves was studied. The scientific and production experiment was carried out on the basis of a dairy farm of the State «Kupinskoe» Unitary Enterprise of the Samara region involving 30 Holstein-Friesian calves. The biological effect of the drug is provided due to its adsorption properties, the ability to enhance the activity of a number of enzyme systems and increase the digestive and systemic immunity of the body. The drug use increases the integration intensity of animals: the amount of total protein in the blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p<0.05), albumin – by 9.2% (p<0.01), compared with the animal data of con-trolled group. The Bisolbi indication contributed to an increase in the intensity of carbohydrate-lipoid metabolism: the cholesterol amount was higher by 23% (p<0.01), the glucose content – by 0.4 mmol/l (p<0.05) in the blood of 120 day old calves of the experimental group, compared with the data of controlled animals. It was found that the body weight of calves in the control group of 100 days age was 105.23±2.11 kg, in the experimental group – 108.6±2.19 kg, which is 3.37 kg higher. The average daily weight gain of animals in experimental group was signif-icantly higher by 0.075 kg (p<0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p<0.05), the average daily weight gain by 0.080 kg (p<0.05), compared with the data of the controlled ani-mals. The indication of Bisolbi 5-10 ml (LLC «Bisolbi-Inter») to calves daily for 2 months resulted in an additional profit constructively of 137 rubles from each head.

The objective of the current study was to examine the effects of mannan-oligosaccharides or inulin on HF dairy heifers’ starter feed intake and daily weight gain in farm situations. We measured these parameters across two experiments. In Trial 1 (T1), next to the control group, 15-15 HF heifers received MOS or inulin supplementation from 1st day of age to weaning. The amount of the supplementations changed according the calves’ age and the amount of milk replacer from 12 g to 24 g/calf/day. We measured the individual feed intake daily, the live weight at 0, 14, 21 and 60 days. In the second experiment (T2) we used 30 HF heifers also in three group (Control, MOS, Inulin) but we gave more from the experiment materials (28 g/calf/day MOS or Inulin). We started dosing the supplements with the colostrums feeding, and gave up on 14th day of age. We also measured the individual feed intake daily and the live body weight (BW) at 0, 14, 28, 42 and 56 days. The treatments in T1 did not cause significant differences in average feed intake, body weight and average daily weight gain. When the calves got the supplementation with colostrum too, the ADWG was significant lower in the group fed inulin than control and group fed MOS (P<0.05). We calculate the ADWG all of the experimental periods. From 0 to 14 day, and from 0 to 56 day the ADWG in inulin group was lower than control group, but the datas of group MOS did not differ from the others. Due to the distribution of the birth weights, the lower ADWG did not manifest in differences in body weight in other points of the experiments. We did not find an interaction between the treatments and the daily feed intake of calves. According with our measurements,

This study investigates the effect on performance, carcass and meat characteristics of increasing the forage level in the diet of fattening Tudanca young bulls using silage as the forage source as compared with a conventional ad libitum straw plus concentrate diet. Twenty two Tudanca young bulls were assigned to three different finishing diets: ad libitum grass silage plus ad libitum concentrate (GS-AC), ad libitum grass silage plus concentrate limited to a half of the intake of the ad libitum group (GS-LC), ad libitum barley straw plus ad libitum concentrate (Str-AC) and then slaughtered at around 11 months of age. GS-LC diet resulted in relation to GS-AC and Str-AC diets in lower (p≤0.05) average daily weight gain (750 vs 1,059 and 991 g/animal/day, respectively), lower (p≤0.05) carcass weight (133 vs 159 and 152 kg, respectively) and carcasses with slightly lower conformation scores. Although GS-LC diet allowed for a lower dependence on concentrate (372 vs 657 and 729 kg/animal, respectively), economic margin was similar for the two GS groups (-63.1 and -64.1 vs -91.8 €/head). The polyunsaturated/saturated fatty acid ratio was the lowest (p≤0.05) in GS-AC meat (the group showing the highest IMF levels) and the ratio n-6/n-3 was the highest (p≤0.05) in Str-AC meat. GS-LC meat showed higher collagen content and Str-AC meat presented higher cohesiveness, springiness and chewiness values. Results suggested that the substitution of straw by grass silage and the restriction of the concentrate level could be recommended for finishing young Tudanca bulls in indoors systems.

Abstract. We evaluated temperament of sheep using two temperament tests: temperament score test and flight test. Temperament score test: behaviour of animals was assessed in a 5-score system while weighing, spending 30 s on the scale. Flight time test: the time taken by an animal to move a set distance (1.7 m) after exiting a weighing scale into an open yard. 10 rams, 22 ewes Hungarian Merino, 13 rams, 19 ewes German Merino and 12 rams, 16 ewes German Blackhead lambs were lot-fed on 49 days, after weaning. The temperament score test was not related to the weight at weaning, therefore the measurement of the temperament was not affected by the weaning process (P>0.10). The gender not affected the temperament scores in either of observations or genotypes. In this investigation German Blackhead lambs were calmer, than Hungarian Merino lambs. The evaluation of the effects of temperament (temperament score test [TS] and flight time test [FT]) on body weight showed that lambs with calm temperament had higher weight at the end of fattening (TS: 44.88 kg and FT: 42.37 kg) and higher average daily weight gain as well (TS: 492.18 g/day and FT: 430.03 g/day), compared to nervous animals (TS: 36.20 kg and 330.08 g/day, P<0.001; FT: 36.73 kg and 345.77 g/day, P<0.05). The lambs with good temperament had better fattening performance (higher weight at end of fattening, faster weight gain) than nervous lambs.

An eight weeks restricted feeding trial was conducted to investigate the effect of restricted feeding and strain on the growth performance and haematological parameters of two strains of pullet chicks. Five hundred and forty chicks comprising of Isa Brown (270) and Bovans Nera (270) strains were assigned to six treatments arranged in a 2 x 3 factorial arrangement of Isa Brown and Bovans Nera on ad libitum (R ), skip-a-day (R ) and skip-2-days (R ) restrictions per week, respectively. Final live weight and weight gain of pullet chicks reduced (P < 0.05) with increasing level of feed restriction. Chicks on ad libitum showed improved (P<0.05) final live weight and weight gain. Results showed significant (p<0.05) reduction in feed intake and body weight of chicks due to restricted feeding. The birds maintained on R feed restriction group recorded the highest significant (p<0.05) values of final body weight (544.57g), feed intake per day (33.70g/day) and daily weight gain (9.82g/day). R birds recorded significantly (p<0.05) higher values of final weight, feed intake and weight gain when compared with R birds with final body weight of 480.84g, daily feed intake of 28.42g/day and daily weight gain of 8.48g. Furthermore, Bovans Nera pullet chicks recorded significantly higher (p<0.05) final weight and daily weight gain when compared with the Isa Brown birds of same age. The R pullets had significantly higher (p<0.05) white blood cells when compared with the R and R birds. Heterophil/lymphocyte ratio (0.52) was  significantly (p<0.05) lower with the Isa brown birds.

This study examined the relationship between carcass composition and performance traits of local turkey fed starter diet (30.2% protein, 2950 kcal/kg ME). At 8 week of age, male and female chicks were separated and reared in individual cages until 16 weeks of age. At the end of the experiment, the birds were slaughtered and carcasses were analyzed for chemical composition to predict chemical composition (moisture, ash, protein and fat) from performance traits such as initial body weight (g) at 8wk, final live body weight (g) at 16wk, daily weight gain (g), daily feed intake (g), feed conversion ratio, daily protein intake (g), protein conversion ratio, dressing-out percentage. There were significant correlations between moisture, protein and fat; between ash, protein, fat and dressing-out percentage; between protein, fat and dressing-out percentage; between fat, moisture, ash, protein, live body weight, feed conversion ratio, protein conversion ratio and dressing-out percentage. Although the coefficient of correlation (R2) for prediction equations was not high, the moisture content equation depends on feed conversion ratio while for ash, protein and fat depends on dressing-out percentage.

The Relationship

Abstract: The objective of this work was to assess the effect of genetic group and heterosis on the relationship between body weight and morphometric measurements, in purebred and crossbred animals from the second (G2) and third (G3) generations of Nellore and Charolais calves. Body weight (BW), average daily weight gain (ADG), foreleg circumference (FC), thoracic girth (TG), body length (BL), and croup height (CH) were measured at birth and at 63, 210, and 365 days of age in animals from G2 and G3. Charolais animals were superior to Nellore ones for gains BW, ADG, BL, and TG, as well as for the ratio between BW gain and CH gain; Nellore animals were superior for CH gains. Crossbred animals of both generations were superior to the purebred animals for gains of BW, BL, and CH. In G2, the predominance of Charolais genes resulted in greater gains of BW, ADG, FC, and TG. The G3 animals were superior to the purebred animals for ADG, FC, and TG. No differences were found for the ratio between gains of weight and morphometric measurements. Heterosis and complementarity are apparent for weight and body measurements of crossbred calves from rotational crossings.

Abstract Two experiments were conducted to investigate effects of feeding graded levels of PBM on performance of weanling pigs and to evaluate feed preference for PBM-based diets relative to spray-dried plasma protein (SDPP)-based diets. A third experiment evaluated PBM in grower diets on performance. In Exp. 1, 120 pigs [body weight (BW) 7.1 ± 0.6 kg] were randomly allotted to 1 of 5 treatments (0, 1, 2, 3, or 5% PBM) and housed 4 pigs/pen for a 28-d growth trial. In Exp. 2, 60 pigs (BW 6.7 ± 1.4 kg) were randomly allotted to 1 of 3 comparisons including: Comparison 1) 0% PBM vs. 2% PBM, Comparison 2) 0% PBM vs. 2% SDPP, and Comparison 3) 2% PBM vs. 2% SDPP and housed 4 pigs/pen for a 28-d preference trial; pigs were provided ad libitum access to feeders; feeder location was switched 3 times/wk. In Exp. 3, 120 pigs (BW 25.9 ± 2.1 kg) were randomly allotted to 1 of 4 treatments (0, 1.25, 2.5 or 5% PBM) and housed 5 pigs/pen for a 41-d growth trial. Increasing PBM from 0 to 5% in Exp. 1 resulted in no differences in ADG (398, 417, 424, 432, and 428 g) or G:F (0.675, 0.686, 0.733, 0.711, and 0.717). Feed preference results (Exp. 2) demonstrated that pigs consumed a higher percentage (76 vs. 24%, P &lt; 0.01) of their total feed intake from the 2% PBM-based diet compared to the 2% SDPP-based diet (Comparison 3). In Exp. 3, increasing PBM for grower pigs resulted in no differences in ADG (1007, 1025, 1002, and 1025 g) or G:F (0.484, 0.472, 0.484, and 0.478). Thus, feeding PBM up to 5% of the diet had no effect on overall performance of nursery or grower pigs, indicating it is an acceptable option as a feed ingredient.

AbstractForty-four Borana × Friesian F1 crossbred calves born to Borana (Bos indicus) cows were randomly assigned to either suck their dams hvice daily or bucket-feeding with 1341 milk over a 57-day pre-weaning period. Their dams were also allocated either to a supplement group with grass hayad libitumand 5 kg per head per day of a concentrate ration or to an unsupplemented group withad libitumgrass hay only. Calves were fed in individual boxes in a calf house. The mean birth weight of calves was 24·8 (s.e. 1·8) kg. Suckled calves were heavier (P < 0·01) at weaning (47·7 (s.e. 1·9) v.37·1 (s.e. 1·8) kg) and had faster pre-weaning growth rate (411 (s.e. 30)v.215 (s.e. 29) g/day) than bucket-fed calves. Calves which sucked supplemented cows were heavier (P < 0·001) at weaning (51·2 (s.e. 2·6)v. 44·2 (s.e. 2·6) kg), had faster (P < 0·01) pre-weaning growth rate (477 (s.e. 41)v.346 (s.e. 41) glday) and higher (P<0·01) daily milk intake (2·6 (s.e. 0·2)v.1·6 (s.e. 0·2) I/day) than those which sucked unsupplemented cows. Mean concentrate intake was 302 (s.e. 30) g/day for bucket-fed calves and 341 (s.e. 33) and 408 (s.e. 33) g/day for calves which sucked supplemented and unsupplemented cows. Cow milk production was higher (P < 0·01) in suckled than in milked cows (3·3 (s.e. 0·2)v.1·0 (s.e. 0·2) I/day) and in supplemented than unsupplemented cows (3·9 (s.e. 0·2)v.2·7 (s.e. 0·2) I/day). Concentrations of milk protein, fat and total solids averaged 39 (s.e. 15), 49 (s.e. 16) and 143 (s.e. 21) g/kg, respectively and were not significantly influenced by either concentrate supplementation or suckling. Restricted suckling and early weaning coupled with appropriate calf and cow feeding regimes could be one of the alternatives for calf rearing under smallholder and small scale peri-urban dairy production systems. However, further studies are warranted to evaluate the effects of such a strategy on both calf and cow performances under these production systems.
