Intensive System

The growth of 81 indigenous Arbia goat kids reared in an intensive system in Setif in northeastern Algeria was observed between birth and 70 days of age. The kids were dam-raised during the first month and then provided with 150 g/head/day of a total mixed ration and oat hay. The kids’ live weights were assessed at fasting and at different ages: 0, 10, 21, 30, 42, 60, and 70 days. The average daily gains (ADG) were also calculated. Growth results were presented for all kids by sex and litter size. The average birth weight was W0 = 2.53±0.19 kg, while the average weight at 70 days was W70 = 10.1±1.54 kg, which correspond to an overall daily weight gain of ADG0-70 = 108±21 g/day. The study showed that birth weight was affected by litter size, while growth after birth was mainly affected by sex. Birth weights were similar between males and females, but males grew faster (p<0.001) after birth. Single kids were heavier (p<0.05) than twins at 70 days of age, which is the consequence of a heavier birth weight and a faster growth rate in the first 10 days after birth (ADG0-10). After 10 days, litter size did not affect ADG. Compared to other indigenous populations, Arbia goat kids demonstrated valuable growth potential for meat production.

<p>The aim of this study was to evaluate and compare the performance of Brangus calves at weaning under grazing conditions, and determine the influence of the sex on its performance. This study was conducted in the Cartago municipality (Colombia), in a herd dedicated to the production of beef with Brangus breed. The data were analyzed by ANOVA with a 95% significance using the statistical software InfoStat 2015. Full records of second lactation cows that were served by the same bull were evaluated to reduce the error factor. The variables evaluated were: weight at birth, weight at weaning, meat production index and average daily gain (ADG). The following model of age at weaning was considered as a covariate: Yij=u+Ti+BXij+Eij. The weight at birth was 33.22±1.86 and 31.88±0.89 kg for males and females respectively, weight at weaning was 246.00±51.69 and 225.81±21.78 kg respectively, rate of production was 0.64±0.12 and 0.62±0.05% respectively, ADG was 890±280; 850±100 grams/day respectively, and age at weaning of 251.78±44.01 and 228.19±16.30 days respectively. Only statistical significant difference for weight at birth (p=0.0286) was observed. In conclusion, both males and females Brangus showed differences in birth weight; however, differences in meat production levels are not significant since these reach at weaning similar weight, meat production index and average weight gain. In this sense, the productive trend may be similar at post-weaning stage, being feasible to employ both males and females interchangeably for the production of beef; additionally, the heifers can arrive faster at age for bull service.</p>

Abstract. A study was conducted to find out the effect of birth weight and sex on growth rate of piglets in pre-weaning period. A total of 466 piglets from 48 litters of multiparous sows (Landrace) were involved in the experiment. Using a clustering approach piglets were assigned into three birth weight groups (Heavy (H), Intermediate (I), Light (L)). For the analysis of growth performance, pigs were weighed every 7 days until weaning at 28 days of age and average daily gain (ADG) was calculated. During lactation, body weight of L piglets was 5.5-fold increased, whereas the increase in I and H piglets were only 4.7-fold and 3.4-fold, respectively. Piglets of L group were significantly lighter at all studied ages compared to piglets of I and H group. The highest ADG was noted in the second week for all three groups; thereafter it decreased in H and L piglets (24% and 17%, respectively). The average birth weight of piglets was positively and significantly correlated with body weight at days 7, 14, 21 and 28. Sex did not affect significantly the ADG of the investigated animals during the four weeks of lactation. The present results indicate that neither milk production after the second week of lactation nor consumption of creep feed are sufficient enough to cover nutrition needs of fast growing piglets. There’s still a lack of optimization of nutrition in pre-weaning period especially for heavier piglets with their higher growth potential.

<span style="font-size: small;"><span style="font-size: 13px; line-height: 14px;">Thi study evaluated the effect of female body weight at conception (FWC), season of mating (SM), type of mating (TM) and litter size at birth (LSB) on the litter performance in a heterogeneous Nigerian population of rabbits. Data on 116 litters from 10 bucks and 48 does across three parities were analysed. Reproductive traits evaluated included LSB, number born alive (NBA), litter sizes and weights at 7, 14 and 21 d post-kindling, pre-weaning survival rate (SR) and daily weight gain of kits from kindling to weaning (DWG). A fi xed linear model that included FWC (light and heavy does), TM (homospermic and heterospermic matings), LSB classes (low, medium and large) and SM (rainy or dry) was used. Results showed that heavier does at concenption showed higher performance for LSB and NBA (P&lt;0.05) than lighter does. Average weight of kits at kindling and at 28 d, as well as kit SR and DWG, were signifi cantly higher in low-sized litters, when compared with intermediate- and large-sized litters (P&lt;0.05). LSB, NBA and litter size at weaning were higher in litters produced by heterospermically mated does compared with homospermically mated does. Season of mating affected LSB and NBA (P&lt;0.05), being signifi cantly larger the litters in the rainy season.</span></span>

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.

A complete diallel using three inbred strains of mice (C3H/He, C57BL/6J and SWR/J) was made to examine preweaning growth of young, the weight of mammary glands of mothers and the relationship between them. Litter sizes were standardized to either six or eight at birth.The differences between strain-of-dam, strain-of-sire and litter size groups in average body weight of full sibs at 12 days were not significant. The difference between litter size groups in weight of dried-defatted mammary gland of mothers 12 days after delivery (DDMW) was significant. When average birth weight was fixed, the partial correlation between DDMW and 12-day weight, calculated within litter size and mating class, was +0.54. Heterosis in average birth weight and 12-day weight was observed. Relationships between preweaning growth criteria are discussed.

Object Children younger than 1 year of age are unique in their physiology and comorbidities. Reports in the literature suggest that the risk factors for shunt infection may be different in this population compared with older children. Importantly, these infants often have other congenital malformations requiring various surgical interventions, which impose an additional risk of infection. Methods In the 3-year period between 2008 and 2010, 270 patients underwent initial CSF shunt placement during the 1st year of life. Clinical characteristics, hospital course, and shunt infections were prospectively recorded in the practice and hospital electronic medical record. Special attention was given to types and timing of other invasive procedures and their relationship with shunt infection. Results The average gestational age was 33.6 weeks, and the average birth weight was 2333 g. The average weight at the time of shunt insertion was 4281 g. Prior to shunt insertion, 120 patients underwent 148 surgical procedures, including ventricular access device insertion (n = 63), myelomeningocele closure (n = 37), and cardiac procedures (n = 11), among others. In the 12-month period after shunt insertion, 121 of the 270 patients underwent 135 surgical procedures, which included 79 CSF shunt revisions. Shunt infection occurred in 22 patients, and organisms were identified in 20 cases. Univariate analysis showed that of the very prematurely born infants (gestational age < 30 weeks), those who underwent preshunt cardiac surgery and any surgical procedures within 30 days after the shunt insertion were at a greater risk of shunt infection. In multivariate analysis, preshunt cardiac surgery and surgical procedures within 30 days postshunt placement were significant risk factors independent of gestational age, birth weight, and history of shunt revisions. Conclusions The results of this study suggest that surgical procedures within 30 days after shunt insertion and preshunt cardiac surgery are associated with a greater risk of shunt infection in children in whom these devices were inserted during the 1st year of life.

Abstract The red-rumped agouti (Dasyprocta leporina) produces precocial young and is the most hunted and farmed game species in several Neotropical countries. An understanding of the reproductive biology, including the relationship between litter size and teat functionality is crucial for conservation management of this animal. In precocial mammals, as the red-rumped agouti, maintaining maternal contact to learn foraging patterns may be more important than the energy demands and nutritional constraints during lactation and suckling may not play important roles when compared to altricial mammals. Therefore, in this study we evaluated the relationship between mammary functionality with litter size, litter birth weight, and parturition number in captive red-rumped agouti. Functionality was assessed by manual palpation of teats from un-sedated females (N=43). We compared the average birth weight of all newborns, male newborns and female newborns among agoutis with different litter sizes and different parturitions by one way ANOVA’s, while Pearson’s Chi-squared tests were used to detect relationships between teat functionality, litter size, and parturition number. Parturition number had no effect on the mean birth weight of all young (F0.822, P > 0.05), male young (F0.80, P > 0.05) or female young (F0.66, P > 0.05) in the litters. We found (i) no significant correlations (P > 0.05) between teat functionality and litter size and (ii) no significant correlations (P > 0.05) between teat functionality and parturition number. This suggests that whilst all teat pairs were functional, functionality was a poor indicator of litter size; suggesting that female agouti young may not have a high dependency on maternal nutrition; an possible evolutionary strategy resulting in large wild populations; hence its popularity as a game species.

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.

Correction: On 29th April 2015 the page numbers of this article were changed from 167-173 to 169-175An investigation was conducted to determine the comparative growth study of supermale tilapia and monosex tilapia in earthen mini ponds from May-July 2012. Four treatments were considered having two replicates. For supermale tilapia treatments were named as ST1 and ST2 and for monosex tilapia were MT1 and MT2. All the fish were of same age group having mean body weight of 1.4 g. Feeding frequency in all the treatments were two times a day. Fish were fed diet at a rate of 30% of their body weight for the first thirty days that was gradually reduced to 15% for the next thirty days and 5% till the termination of the experiment. Final weight, weight gain, average daily weight gain, % weight gain and production of supermale tilapia were significantly (p<0.05) higher than those of monosex tilapia. But SGR (% day), FCR and survival rate of supermale tilapia were not significantly (p>0.05) varied. However, the result of the present study showed that the best weight gain of 124.85 g was observed in ST1 after 90 days culture period. Average weight gain (g) were 1.39, 1.16, 1.14 and 1.05, SGR (per day) were 2.17, 2.09, 2.08 and 2.04%, FCR were 2.98, 2.65, 2.84 and 2.57, survival rate were 96, 94.50, 95 and 91% and fish production were 5053.92, 8926.10, 4108.07 and 7821.41 kg/ha in ST1, ST2, MT1 and MT2 respectively. The present research findings suggested that supermale tilapia has significantly high growth potential compare to monosex tilapia under mini ponds culture condition.Res. Agric., Livest.
