Abstract. Goats are more and more used as shrub-fighters in landscape conservation. Important traits for the extensive production system are vitality and robustness but also acceptable meat production of kids during the grazing period. To investigate possible selection traits for "landscape conservation suitability", 35 kids were investigated for vitality parameters directly after birth whereas all-in 65 kids were investigated for performance traits under extensive grazing conditions. Birth weight as a parameter for vitality and survivability of kids was significantly influenced by sex, genotype and age of doe. Besides rectal temperature 3 hours p.p., other factors regarded as possible vitality parameters were not influenced by birth weight. Birth weight had a significant influence on daily weight gain during the extensive period; kids with higher birth weight showed slightly better weight gain. Birth weight had also a significant effect on some carcass parts, indicating that higher birth weight implies a high probability of a better carcass performance especially in some valuable parts. Still, the effect of the genotype on carcass performance was considerably higher than any other investigated effect. As a result of the present study, there are indications that birth weight can be taken as a parameter for kids' vitality. Also, it is indicated that goats of Cashmere type as fibre animals are not appropriate for landscape management whereas crossbred animals with a meat, dairy and fibre component in their genotype showed to be a vital animal with acceptable efficiency also in harsh conditions and with an average meat and carcass performance.

SUMMARYIn three successive years cows from an Aberdeen Angus cross Shorthorn herd were mated to pedigree Charolais, British Friesian and Hereford bulls. A comparison of the progeny of the three breeds of sire under controlled conditions was therefore possible using a random selection of dams for mating, and identical rearing of the calves. Results for live-weight gain of the suckled progeny were analysed and showed superiority of the Charolais breed over the other two when used in this form of beef cattle production.For birth weights and daily live-weight gains, particularly during the grazing period, the Charolais cross progeny showed superiority over the other two. There was a consistent although not always statistically significant tendency for these differences between the breed crosses to occur in the male calves only, the females showing little difference between breeds. The data also showed highly significant relationships between gestation period and birth weight, both within and between breed crosses.

The aim of the study was to evaluate the growth rate and selected carcass and meat quality parameters in bulls fed a high-grain diet and to compare the results with those obtained in bulls fed a diet based on preserved roughage. The trial included 18 Czech-Pied bulls fed a diet with a high proportion of concentrated feed and 18 Czech-Pied bulls fed a diet based on maize silage, used as a control group. The trial was launched after the weaning of calves. During the fattening period, live weight and average daily weight gain were monitored. The bulls were slaughtered at the live weight of 550–600 kg, the mean age at slaughter was 473 days for the high-grain diet group and 474 days for the control group. The carcasses were classified to SEUROP quality grades, and carcass gain and dressing percentage were calculated. Samples of <I>m. longissimus pars thoracis</I> were taken from five bulls in each group to examine selected meat quality parameters. In the period from weaning to slaughter the high-grain diet bulls and the control bulls achieved the average daily weight gain of 1.29 kg and 1.21 kg, respectively. Differences between the groups were not significant. The high-grain diet group showed higher average carcass weight and higher carcass weight gain, differences between the groups were not significant, either. As to meat quality parameters under study, a significant difference was found only in meat lightness (L*), with the mean value in the high-grain diet group being significantly (<I>P</I> ≤ 0.01) lower than in the control group. The other meat quality parameters did not show any significant differences between the groups. In this study, the high-grain diet gave similar performance as the maize silage-based diet in fattening bulls. The high-grain diet group and control group showed comparable average daily weight gain and selected carcass and meat quality parameters.

This study was conducted to compare the growth and economic performances between Swamp and Murrah crossbred buffaloes. The records of 108 Swamp and 276 Murrah crossbred buffaloes born between January 2010 and December 2015 were used in this study. The farm was practicing an extensive grazing system without supplementation from January 2010 to December 2011 (pre-intervention) and a new implementation of supplement in the feeding regime from January 2012 to December 2015 (post-intervention). The birth, weaning, and body weight at three monthly intervals, number of calves born, and mortality rate of calves at different years and during pre- and post-intervention were analyzed using a general linear model procedure. The interventions in 2012 had a positive effect on increasing the number of calves born for both breeds, average birth weight, economic performance, and reduce mortality calf rate. As a result, the birth weight of Murrah crossbred buffaloes was higher (36.63 ± 0.50 kg) than Swamp buffaloes (34.69 ± 0.40 kg) (p < 0.05). The average pre-weaning daily weight gain for Swamp and Murrah crossbred buffaloes was 0.73 and 0.98 kg/day (p < 0.05), while the average post-weaning daily weight gain was 0.39 and 0.44 kg/day, respectively (p < 0.05). The Swamp and Murrah crossbred buffaloes achieved the targeted market weight of 250 kg at 18 and 15 months old, respectively, while the targeted breeding weight of 385 kg was achieved at 30 and 26 months old, respectively. In this farm, on average a total of 64 calves were born yearly, with the ratio number of born calves per number of mated dams recorded higher in Murrah crossbred buffaloes as compared to Swamp buffalo (0.64 vs. 0.37) (p < 0.05). Furthermore, the average number of calves born in the post-intervention period (January 2012–December 2015) was significantly higher than in the pre-intervention period (January 2010–December 2011), respectively (Swamp: 23 vs. 8 and Murrah crossbred: 53 vs. 31, respectively) (p < 0.05). Partial budget method was used to estimate the net gain or loss between the two breeds. The average annual revenue was 2304.14 MYR (566.13 USD) for Swamp buffaloes and 4531.50 MYR (1113.39 USD) for Murrah crossbred buffaloes. The average annual cost saving was 340.02 MYR (83.54 USD) for Swamp and 215.75 MYR (53.01 USD) for Murrah crossbred buffaloes. On the other hand, annual added cost was 84.95 MYR (20.87 USD) for Swamp and 96.76 MYR (23.77 USD) for Murrah crossbred buffaloes. Therefore, the annual net benefit was 2559.21 MYR (628.80 USD) for Swamp and 4650.49 MYR (1142.63 USD) for Murrah crossbred buffaloes. As a conclusion, this study had shown that the higher average daily weight gain contributes to better cost savings, as shown by the crossbred buffaloes.

<p>The current study aims to assess the effect from crude glycerin inclusion (0, 7, 14, and 21% dry matter) in the diet of slaughtered lamb on their development, nutrient consumption, biometrical measures, diet economic viability and carcass features. Thirty two (32) non-castrated male Texel lambs were used in the study, they presented mean initial weight 15.9 ± 4.1 kilos and were distributed in casual outlining. They were fed with four treatments, with 8 repetitions. Animals were slaughtered when they reached approximately 35 kilos. The mean total weight gain was 20.72 kilos and mean daily weight gain was 260 grams. No changes resulted from glycerin use. The carcass performance was similar among treatments (P&gt;0.05) and the cold carcass performance (CCP) was 44.68%. There were no effects (P&gt;0.05) on the loin eye area (LEA) and on fat thickness (FT); they showed averages of 13.66 cm2 and 0.84 mm, respectively. Nutrition cost per animal during the whole confinement period varied between R$82.60 (eighty-two Reais and forty-eight cents) to R$92.48. The smallest nutrition amount consisted of 21% crude glycerin. The gross profit ranged from R$30.75 to R$ 34.01 per animal, for feed without glycerin and 21% glycerin, respectively. Animal development was not impacted by glycerin introduction, even with decrease on dry and organic mass consumption. The result showed that crude glycerin inclusion might be used in lambs’ diet. Whenever there are big amounts of feed involved in the process, the 21% crude glycerin addition may be an interesting cost reduction. Seventy eight percent (78%) glycerol crude glycerin to replace corn-based feed in confined lambs’ diet appeared to be nutritionally and economically viable.</p><p><strong> </strong></p>

Objectives: To determine the effectiveness of Kangaroo Mother Care in subgroups of LBW babies-Preterm AGA, Preterm SGA and Term SGA, To assess any differences in benefits of KMC in relation to duration in the subgroups, To assess weight gain difference in NICU and at home at first follow up visit and up to 40 weeks of follow up to Preterm AGA, Preterm SGA and till gain of 2500g in Term SGA babies. Study design: Prospective observational study. Setting: NICU in a large teaching institute, department of pediatrics, Mahatma Gandhi Memorial Hospital, North Telangana. Subjects and Methods: 240 neonates with birth weight <2500g, hemodynamically stable. Intervention: The subjects are classified into three subgroups-based on gestational age (by new Ballard’s score) and by weight (Lubchenco’ s charts) into Preterm Appropriate for gestational age (PT AGA) (102), Preterm Small for Gestational Age (PT SGA) (88) and Term Small for Gestational age (T SGA) (50). Further categorized into <=32 wks,33-34wks,35- 36wks,>=37wks.KMC was given to all subgroups at hospital and home with mean duration of 9+2hrs at hospital and 5+2hrs at home. Outcome Measures: Growth measured by average daily weight gain, mean weight gain, (weight was measured by electronic weighing scale (seca), head circumference (measured by non-stretchable and non-metallic tape) and total length (measured by infant meter) in follow up to 40 weeks of corrected gestational age in Preterm and up to gain of 2500g in Term SGA were assessed with KMC. Results: Better weight gain was noticed in all the 3 subgroups of LBW neonates with KMC at hospital and home. In spite of lower duration of KMC at home PT AGA (33-34 weeks) subgroup has the highest weight gain (24.5+5.5g/day, p=0.003), highest head circumference gain (0.70+0.5cm/week, p=0.002), highest length gain (0.90+0.6cm/week, p <0.008). The time taken to reach full feeds and the time to reach initiation of direct breastfeeds were comparable in all subgroups but attained much earlier in PT AGA (33-34wks) and PT AGA (35-36wks). Duration of hospital stay is least in PT AGA with mean of 12.68 ± 6.37 days.KMC significantly reduced the incidence of apnea in all subgroups of LBW babies. All babies were on exclusive breastfeeds at the end of the study (98%). Conclusion: We conclude by this present study that KMC improves growth in all sub groups of LBW infants. KMC has significantly reduced the incidence of co mortifies like apnea, hypothermia, hypoglycemia in all the subgroups of LBW babies. KMC is cost effective, easily accessible and acceptable not only to mothers but also by majority of the family members

In several species, nuclear transfer causes a high frequency of fetal loss, high birth weight, malformations, and neonatal death. This study investigates the fetal development of porcine embryos produced by handmade cloning (HMC) and compares the piglets with littermates produced by traditional cloning (TC). HMC embryos were produced from one fetal cell line, LYxD (Landrace/Yorkshire x Duroc) and TC from another (LYDxLYD). For transfer, 11 sows were weaned, and at cycle stage Day 4 after heat, they were anesthetized in lateral recumbence. Through an abdominal incision 40–60 Days 5–7 embryos (69% HMC + 31% TC) were transferred to the upper uterine horn. The tip of the uterine horn was punctured with a blunt 18G needle and a temporary catheter introduced to absorb the blood before inserting an insemination catheter (J-IUIC-351341 Insemi-Cath; Cook Ireland Ltd., Limerick, Ireland) 5–6 cm into the horn and releasing the embryos. Pregnancy was examined by ultrasonography every second week to Day 100. Caesarian sections were performed at Day 115, 24 h after injection of PGF2 (175 �g Estrumate�; Pitman-Moore Ltd., Harefield, UK). The piglets were fed with 15 mL kg-1/3 h colostrum through a stomach tube for the first 12–24 h, until they were left with their dam. Body weight, blood values (oxygen tension, and glucose and hemoglobin concentrations), and body temperature were recorded at birth, 24 h, and 3 weeks of age. The data were analyzed by Fisher's Exact test and are given as LS means � SEM values with a significance level of P &lt; 0.05. The pregnancy rate was 6/11 (55%), with 2 pregnancies developing to term, 2 ongoing (Day 100 and Day 60), and 2 lost (about Day 35). So far, the litter sizes were 3 (1 TC, 2 HMC) and 10 (2 TC, 8 HMC) live piglets, respectively. The mean birth weight of the TC offspring (1045 � 135 g) was lower than that of the HMC piglets (1614 � 177 g) and that of normal piglets on the farm (1520 � 240 g; P &lt; 0.05). One of the HMC piglets of the first litter was rather oversized (2690 g) and another showed rigid flexure of a carpal joint. All other piglets appeared normal on gross morphology and behavior. Blood values were similar for HMC and TC piglets, but the body temperature at Day 0 (36.3 � 0.2 vs. 35.1 � 1.1�C; P &lt; 0.05) and the daily weight gain during the first week (129 � 21 vs. 74 � 13 g; P = 0.06) tended to be higher for the HMC piglets. After 24 hrs, the mean blood glucose concentration was higher in the HMC than in the TC piglets (6.09 � 0.74 vs. 3.67 � 0.19 mmol L-1) and similar to farm piglets of the same age (6.93 � 0.44 mmol L-1), but the difference was not significant after 3 weeks. These preliminary results demonstrate for the first time that HMC in pigs can result in an acceptable pregnancy rate, birth rate, and litter size. The minor differences in birth weight, weight gain, and blood glucose observed between HMC and TC offspring may be explained by the different cell lines used for the 2 methods, and are under current investigation.

Abstract Objectives of this study were to evaluate birth weight (BW), weaning weight (WW), and average daily weight gain (ADG) of female calves carrying the SLICK1 allele, i.e., the slick gene. Holstein cows in four dairy farms located in central California were inseminated with semen from two heterozygous slick Holstein sires to produce slick and non-slick calves. Calves were born during the cool season (November 2019-March 2020). BW was recorded for 125 calves in four farms within 24 h of birth; WW was recorded for 92 calves in three farms within one week of weaning. Weaning age was recorded at day of weighing. ADG was calculated as the weight difference between birth and weaning divided by days of age at weaning. Only female calves were used in the analysis. Statistical analyses were performed using the GLIMMIX procedure of SAS version 9.4. The model for BW included the effects of genotype, farm, sire, and the interaction between genotype and farm. The model for WW and ADG included the effects of BW, genotype, farm, weaning age, sire, and interaction between genotype and farm. Significant effects were considered as those with P &lt; 0.05. There was no difference in BW or WW between genotypes (BW: slick=40.1 ± 0.7 vs non-slick=39.7 ± 0.6 kg; P = 0.7 and WW: slick=82.5 ± 2.8 vs non-slick=80.9 ± 2.8 kg; P = 0.6). The mean age at weaning was 64.8 ± 0.4 and was similar for both genotype groups (P = 0.8). As a result, ADG was similar between genotypes (P = 0.7). There was a main effect of farm on BW, WW and ADG. Results indicate that slick heifer calves born in the cool season perform similarly to non-slick calves in regards to birth weight, average daily weight gain, and weaning weight.

The aim of this work was to analyze the growth abilities of bull and heifer calves (n = 190) of the Charolais breed calved in one herd from 2006 to 2011. The evaluation was carried out during the period of calf raising, focusing to the effects of sex, parity and the mating method on live birth weight (BLW) and the live weight at 120 (LW120), 210 (LW210) and 365 (LW365) days of life, as well as the average daily weight gain reached by the age of 120 (G120), 210 (G210), and 365 (G365) days. Statistical analysis was carried out with the use of the SAS 9.3 program. The effect of sex on the live weight and average daily weight gain was statistically significant on the level of P < 0.01 always in favour of the bull calves (BLW +3.05 kg, LW120 +29.35 kg, LW210 +36.98 kg, and LW365 +117.23 kg). The lowest live birth weight was detected in the calves of primiparous cows (BLW = 45.46 kg; P < 0.01). The higher parity, the higher live birth weight was determined, with maximum values in cows from the fourth calving. The trends were similar in live weight at 120, 210 and 365 days of age, when significance level was P < 0.05. The parity effect on the average daily weight gain (G120, G210 a G365) was statistically insignificant (P > 0.05). The effect of embryo transfer (ET) and other commonly used reproduction methods (insemination and natural mating, AI/PP) was evaluated as well as. The calves born after embryo transfer showed a significantly (P < 0.01) higher the live birth weight as well as weight at different ages (BLW +5.85 kg, LW120 +18.15 kg, LW210 +22.94 kg and LW365 +35.43 kg), and G120 only (+100 g×day−1; P < 0.05). These results pointed the suitability of using the biotechnological reproduction methods, especially in relation to the total weight of the reared and fattened animals.
